[source] Predicting physical activity and outcome expectations in cancer survivors: an application of Self-Determination TheoryPSYCHO-ONCOLOGY, Issue 7 2006Philip M. Wilson Abstract The purpose of this study was to examine the contributions of autonomous and controlled motives drawn from Self-Determination Theory (SDT; Intrinsic Motivation and Self-determination in Human Behavior. Plenum Press: New York, 1985; Handbook of Self-determination Research. University of Rochester Press: New York, 2002) towards predicting physical activity behaviours and outcome expectations in adult cancer survivors. Participants were cancer-survivors (N=220) and a non-cancer comparison cohort (N=220) who completed an adapted version of the Treatment Self-Regulation Questionnaire modified for physical activity behaviour (TSRQ-PA), an assessment of the number of minutes engaged in moderate-to-vigorous physical activity (MVPA) weekly, and the anticipated outcomes expected from regular physical activity (OE). Simultaneous multiple regression analyses indicated that autonomous motives was the dominant predictor of OEs across both cancer and non-cancer cohorts (R2adj=0.29,0.43), while MVPA was predicted by autonomous (,'s ranged from 0.21 to 0.34) and controlled (,'s ranged from ,0.04 to ,0.23) motives after controlling for demographic considerations. Cancer status (cancer versus no cancer) did not moderate the motivation,physical activity relationship. Collectively, these findings suggest that the distinction between autonomous and controlled motives is useful and compliments a growing body of evidence supporting SDT as a framework for understanding motivational processes in physical activity contexts with cancer survivors.

[source] Macaque,human interactions and the societal perceptions of macaques in SingaporeAMERICAN JOURNAL OF PRIMATOLOGY, Issue 10 2009John Chih Mun Sha Abstract Humans and long-tailed macaques (Macaca fascicularis) interface in several locations in Singapore. We investigated six of these interface zones to assess the level of conflict between the two species. We observed macaque-to-human interactions and distributed questionnaires to residents and visitors of nature reserves. We observed an average of two macaque-to-human interactions per hour at the sites, which included affiliative or submissive behaviors (46.9%), aggression (19.1%), taking food and other items (18.5%) searching bins, cars, and houses (13.4%), and nonaggressive contact (2.1%). Two-thirds of interactions occurred when a human was carrying food or food cues, and one-quarter occurred when a human provoked macaques. Only 8% of interactions occurred without a clear human-triggered context. Our interview showed one-third of respondents experienced nuisance problems from macaques. They had items taken from them (50.5%) and received threats (31.9%). Residents reported more nuisance problems than visitors, and their perceptions toward macaques differed. Residents were more aware of the consequences of food provisioning and that there were regulations against feeding. Residents fed macaques less and held more negative sentiments toward macaques. Nearly half of the interviewed people held neutral attitudes toward macaques and only 26.2% of respondents thought conflict with macaques warranted urgent action. Nearly two-thirds of the respondents supported education programs to ameliorate human,macaque conflict, and less than 15% supported removing or eradicating macaques. 87.6% felt that it is importance to conserve and protect macaques. Our results show that human,macaque conflict exists in Singapore, but that it may not be severe. Human behavior is largely responsible for macaque-to-human interactions, and thus could be lessened with management of human behavior in interface zones (i.e. restrict food carrying and provocation). Moreover, our interviews shows people living in Singapore value macaques, do not wish them entirely removed, prefer education-based solutions, and consider conservation and protection of them important.

[source] MODELING MEDIATION IN THE ETIOLOGY OF VIOLENT BEHAVIOR IN ADOLESCENCE: A TEST OF THE SOCIAL DEVELOPMENT MODEL,CRIMINOLOGY, Issue 1 2001BU HUANG The social development model seeks to explain human behavior through specification of predictive and mediating developmental relationships. It incorporates the effects of empirical predictors ("risk factors" and "protective factors") for antisocial behavior and seeks to synthesize the most strongly supported propositions of control theory, social learning theory, and differential association theory. This article examines the fit of the social development model using constructs measured at ages 10, 13, 14, and 16 to predict violent behavior at age 18. The sample of 808 is from the longitudinal panel of the Seattle Social Development Project, which in 1985 surveyed fifth-grade students from schools serving high crime neighborhoods in Seattle, Washington. Structural equation modeling techniques were used to examine the fit of the model to the data. The model fit the data (CFI ,.90, RMSEA ,.05). We conclude that the social development model adequately predicts violence at age 18 and mediates much of the effect of prior violence. Implications for theory and for prevention are discussed. [source] Tanning and Cutaneous MalignancyDERMATOLOGIC SURGERY, Issue 4 2008SHERRIF F. IBRAHIM MD BACKGROUND Exposure to ultraviolet radiation (UVR) results in a darkening of the skin known as tanning. Recently, it has been shown that tanning is a response to UVR-induced DNA damage and represents the skin's efforts to protect itself against further injury. Despite the link between UVR and cutaneous malignancy, people continue to pursue tanning from natural and artificial sources. This trend is reflected in the exponential rise in skin cancer incidence. OBJECTIVE The objective of this study was to review our current understanding of the factors controlling the tanning response and the relationship to cutaneous carcinogenesis, as well as the impact that the multibillion dollar tanning industry has had on the practice of dermatology. MATERIALS AND METHODS Extensive literature review was conducted in subjects related to tanning and the relationship to cutaneous malignancy. RESULTS Our knowledge of tanning and its effects on the skin has increased tremendously. It is clear that tanning contributes to the development of skin cancer. Despite this information, the incidence of skin cancer continues to increase exponentially. CONCLUSIONS Skin cancer poses a major public health concern and tanning remains the most modifiable risk factor in its etiology. Social, economic, and legislative issues have become tightly intertwined with the complex nature of human behavior in the continued pursuit of an activity that clearly has detrimental effects on one's health. [source] Mortuary Rituals in Japan: The Hegemony of Tradition and the Motivations of IndividualsETHOS, Issue 3 2006Yohko Tsuji Despite rapid social change, traditional mortuary rituals persist in contemporary Japan, and most Japanese ascribe their continuous compliance with tradition to cultural hegemony. In this article, I explore various other motivational forces behind their actions and illustrates how external pressures and individuals' internal motivations are intricately intertwined to generate human behavior. To do so, I consider the social and personal significance of Japanese funerals, examining rituals not only as an embodiment of sociocultural order but also as a culturally prescribed means to legitimize individuals' actions and define their identity. I also demonstrate the multiplicity and fluidity of cultural discourse and the malleability of tradition as well as individuals' active roles in perpetuating and altering mortuary tradition. Primary data were gathered from participant-observation research in Japan since 1988.

Shea Abstract The East Mediterranean Levant is a small region, but its paleoanthropological record looms large in debates about the origin of modern humans and the fate of the Neandertals. For most of the twentieth century, the Levantine paleoanthropological record supported models of continuity and evolutionary transition between Neandertals and early modern humans. Recent advances in radiometric dating have challenged these models by reversing the chronological relationship between Levantine Neandertals and early modern humans. This revised chronostratigraphy for Levantine Middle Paleolithic human fossils raises interesting questions about the evolutionary relationship between Neandertals and early modern humans. A reconsideration of this relationship moves us closer to understanding the long delay between the origin of morphologically modern-looking humans during the Middle Paleolithic (>130 Kyr) and the adaptive radiation of modern humans into Eurasia around the time of the transition from the Middle to Upper Paleolithic (50 to 30 Kyr). [source] Genetic influences on behavioral inhibition and anxiety in juvenile rhesus macaquesGENES, BRAIN AND BEHAVIOR, Issue 4 2008J. Rogers In humans and other animals, behavioral responses to threatening stimuli are an important component of temperament. Among children, extreme behavioral inhibition elicited by novel situations or strangers predicts the subsequent development of anxiety disorders and depression. Genetic differences among children are known to affect risk of developing behavioral inhibition and anxiety, but a more detailed understanding of genetic influences on susceptibility is needed. Nonhuman primates provide valuable models for studying the mechanisms underlying human behavior. Individual differences in threat-induced behavioral inhibition (freezing behavior) in young rhesus monkeys are stable over time and reflect individual levels of anxiety. This study used the well-established human intruder paradigm to elicit threat-induced freezing behavior and other behavioral responses in 285 young pedigreed rhesus monkeys. We examined the overall influence of quantitative genetic variation and tested the specific effect of the serotonin transporter promoter repeat polymorphism. Quantitative genetic analyses indicated that the residual heritability of freezing duration (behavioral inhibition) is h2 = 0.384 (P = 0.012) and of ,orienting to the intruder' (vigilance) is h2 = 0.908 (P = 0.00001). Duration of locomotion and hostility and frequency of cooing were not significantly heritable. The serotonin transporter polymorphism showed no significant effect on either freezing or orienting to the intruder. Our results suggest that this species could be used for detailed studies of genetic mechanisms influencing extreme behavioral inhibition, including the identification of specific genes that are involved in predisposing individuals to such behavior. [source] Individual differences in allocation of funds in the dictator game associated with length of the arginine vasopressin 1a receptor RS3 promoter region and correlation between RS3 length and hippocampal mRNAGENES, BRAIN AND BEHAVIOR, Issue 3 2008A. Knafo Human altruism is a widespread phenomenon that puzzled evolutionary biologists since Darwin. Economic games illustrate human altruism by showing that behavior deviates from economic predictions of profit maximization. A game that most plainly shows this altruistic tendency is the Dictator Game. We hypothesized that human altruistic behavior is to some extent hardwired and that a likely candidate that may contribute to individual differences in altruistic behavior is the arginine vasopressin 1a (AVPR1a) receptor that in some mammals such as the vole has a profound impact on affiliative behaviors. In the current investigation, 203 male and female university students played an online version of the Dictator Game, for real money payoffs. All subjects and their parents were genotyped for AVPR1a RS1 and RS3 promoter-region repeat polymorphisms. Parents did not participate in online game playing. As variation in the length of a repetitive element in the vole AVPR1a promoter region is associated with differences in social behavior, we examined the relationship between RS1 and RS3 repeat length (base pairs) and allocation sums. Participants with short versions (308,325 bp) of the AVPR1a RS3 repeat allocated significantly (likelihood ratio = 14.75, P = 0.001, df = 2) fewer shekels to the ,other' than participants with long versions (327,343 bp). We also implemented a family-based association test, UNPHASED, to confirm and validate the correlation between the AVPR1a RS3 repeat and monetary allocations in the dictator game. Dictator game allocations were significantly associated with the RS3 repeat (global P value: likelihood ratio ,2 = 11.73, df = 4, P = 0.019). The association between the AVPR1a RS3 repeat and altruism was also confirmed using two self-report scales (the Bardi,Schwartz Universalism and Benevolence Value-expressive Behavior scales). RS3 long alleles were associated with higher scores on both measures. Finally, long AVPR1a RS3 repeats were associated with higher AVPR1a human post-mortem hippocampal messenger RNA levels than short RS3 repeats (one-way analysis of variance (ANOVA): F = 15.04, P = 0.001, df = 14) suggesting a functional molecular genetic basis for the observation that participants with the long RS3 repeats allocate more money than participants with the short repeats. This is the first investigation showing that a common human polymorphism, with antecedents in lower mammals, contributes to decision making in an economic game. The finding that the same gene contributing to social bonding in lower animals also appears to operate similarly in human behavior suggests a common evolutionary mechanism. [source] The surface archaeological record in arid Australia: Geomorphic controls on preservation, exposure, and visibilityGEOARCHAEOLOGY: AN INTERNATIONAL JOURNAL, Issue 2 2009Patricia C. Fanning The conventional approach to assessing the archaeological record in most parts of the world involves a combination of excavation of stratified deposits and extensive survey of surface deposits. Although widely applied in Australia, in both research-based and management archaeology, the method does not conform well to the nature of the surface archaeological record here. Over much of semi-arid and arid Australia, archaeological "sites" are, in fact, accretion phenomena that are not easily interpreted as the outcome of short-term behavioral events. Using results from twelve years of geoarchaeological research in western New South Wales, we demonstrate that there is considerable variability in landsurface age, and hence the "availability" of archaeological surfaces, over relatively short distances. Therefore, it cannot be assumed that stone artifact deposits, for example, that appear to be similar in character are of similar age. Data are also presented that demonstrate that the presence of artifacts on the surface, their apparent absence in sediments buried beneath the surface, and the apparent recent ubiquity of the archaeological record are all a function of geomorphic processes that, at the same time, expose some artifact deposits at the surface and erode and bury others amid large volumes of sediment. Interpreting the surface artifact record within a spatial and temporal geomorphic framework is crucial to understanding the past human behavior that the artifact deposits represent. © 2009 Wiley Periodicals, Inc. [source] Wadi Bakht revisited: Holocene climate change and prehistoric occupation in the Gilf Kebir region of the Eastern Sahara, SW EgyptGEOARCHAEOLOGY: AN INTERNATIONAL JOURNAL, Issue 8 2004Jörg Linstädter Geoarchaeological and chronological evidence from the remote Gilf Kebir Plateau in southwest Egypt suggests a new model for the influence of early and mid-Holocene precipitation regimes on land-use strategies of prehistoric settlers in what is now the center of the largest hyperarid area on earth. We hypothesize that the quantitatively higher, daytime, monsoon summer rainfall characteristic of the early Holocene (9300,5400 14C yr B.P./8400,4300 yr B.C.) resulted in less grass growth on the plateau compared to the winter rains that presumably fell in the cool nights during the terminal phase of the Holocene pluvial (5400,4500 yr B.P./4300,3300 yr B.C.). The unparalleled climatic transition at 5400 yr B.P. (4300 yr B.C.) caused a fundamental environmental change that resulted in different patterns of human behavior, economy, and land use in the canyon-like valleys and on the plains surrounding the plateau. The model emphasizes the crucial impact of seasonal rainfall distribution on cultural landscapes in arid regions and the lower significance of annual precipitation rates, with implications for future numeric climate models. It also serves as an example of how past climate changes have affected human societies. © 2004 Wiley Periodicals, Inc. [source] Imaging genetics and development: Challenges and promisesHUMAN BRAIN MAPPING, Issue 6 2010B.J. Casey Abstract Excitement with the publication of the human genome has served as catalyst for scientists to uncover the functions of specific genes. The main avenues for understanding gene function have been in behavioral genetics on one end and on the other end, molecular mouse models. Attempts to bridge these approaches have used brain imaging to conveniently link anatomical abnormalities seen in knockout/transgenic mouse models and abnormal patterns of brain activity seen in humans. Although a convenient approach, this article provides examples of challenges for imaging genetics, its application to developmental questions, and promises for future directions. Attempts to link genes, brain, and behavior using behavioral genetics, imaging genetics, and mouse models of behavior are described. Each of these approaches alone, provide limited information on gene function in complex human behavior, but together, they are forming bridges between animal models and human psychiatric disorders.

Davey Abstract The experience of being liked is a key social event and fundamental to motivating human behavior, though little is known about its neural underpinnings. In this study, we examined the experience of being liked in a group of 15- to 24-year-old: a cohort for whom forming friendships has a great degree of salience, and for whom the explicit representation of relationships is familiar from their frequent use of social networking technologies. Study participants (n = 19) were led to believe that other participants had formed an opinion on their likability based on their appearance in a photograph, and during fMRI scanning viewed the photographs of people who had purportedly responded favorably to them (alongside photographs of control participants). Results indicated that being liked activated primary reward- and self-related regions, including the nucleus accumbens, midbrain (in an area corresponding to the ventral tegmentum), ventromedial prefrontal cortex, posterior cingulate cortex (including retrosplenial cortex), amygdala, and insula/opercular cortex. Participants showed greater activation of ventromedial prefrontal cortex and amygdala in response to being liked by people that they regarded highly compared to those they regarded less so. Finally, being liked by the opposite compared to the same gender activated the right caudal orbitofrontal cortex and right anterior insula: areas important for the representation of primary somatic rewards. This study demonstrates that neural response to being liked has features that are consistent with response to other rewarding events, but it has additional features that reflect its intrinsically interpersonal character.

[source] Neural connectivity as an intermediate phenotype: Brain networks under genetic controlHUMAN BRAIN MAPPING, Issue 7 2009Andreas Meyer-Lindenberg Abstract Recent evidence suggests that default mode connectivity characterizes neural states that account for a sizable proportion of brain activity and energy expenditure, and therefore represent a plausible neural intermediate phenotype. This implies the possibility of genetic control over systems-level connectivity features. Imaging genetics is an approach to combine genetic assessment with multimodal neuroimaging to discover neural systems linked to genetic abnormalities or variation. In the present contribution, we report results obtained from applying this strategy to both structural connectivity and functional connectivity data. Using data for serotonergic (5-HTTLPR, MAO-A) and dopaminergic (DARPP-32) genes as examples, we show that systems-level connectivity networks under genetic control can be identified. Remarkable similarities are observed across modalities and scales of description. Features of connectivity often better account for behavioral effects of genetic variation than regional parameters of activation or structure. These data provide convergent evidence for genetic control in humans over connectivity systems, whose characterization has promise for identifying neural systems mediating genetic risk for complex human behavior and psychiatric disease.

[source] Characterization of simple sequence repeat variants linked to candidate genes for behavioral phenotypes,,HUMAN MUTATION, Issue 1 2006Zoë Prichard Abstract Simple sequence repeats (SSRs) have traditionally been used as markers in gene mapping studies and typing for forensic purposes. Recently there has been some speculation that this type of genetic variation also plays a more direct role in influencing gene expression and hence complex phenotypic outcomes such as human behavior. For this reason it is interesting to investigate SSRs linked to candidate genes for various complex phenotypes. An economical multiplex PCR-based assay was designed to simultaneously genotype individuals at 15 loci across 10 candidate genes for human behavioural phenotypes, including seven loci previously unreported in Caucasians (five unreported in any population). All loci were tested for Hardy-Weinberg equilibrium and for two-locus Linkage Disequilibrium. Ewens-Watterson neutrality testing indicated possible selection at a previously unreported DRD2 locus. © 2005 Wiley-Liss, Inc. [source] Seasonal variations in [3H]citalopram platelet binding between healthy controls and violent offenders in FinlandHUMAN PSYCHOPHARMACOLOGY: CLINICAL AND EXPERIMENTAL, Issue 7 2005James Callaway Abstract Monthly binding densities (Bmax) of [3H]citalopram to the platelet serotonin transporter (SERT) was measured longitudinally over 1 year in a control group of 18 healthy Finnish male volunteers. Single platelet samples were also analysed from 33 men who were incarcerated for violent crimes during the same calendar year. A statistically significant seasonal variation in SERT Bmax was observed in both data sets, and bi-monthly floating averages for SERT Bmax were calculated and then fit to an annual sinusoidal curve for both groups. The Bmax for platelet [3H]citalopram binding showed a statistically significant (p,=,0.001) seasonal variance between a winter (January,February) maximum of 1590 fmol/mg protein and a summer (July,August) minimum of 1216 fmol/mg protein for the control group, with an R2 of 70% for the annual sinusoidal curve fit. A statistically significant (p,=,0.007) seasonal variance was also observed between a winter (January,February) maximum of 1980 fmol/mg protein and an autumnal (August,September) minimum of 1234 fmol/mg protein for the violent offenders, again with an R2 of 70% for the annual sinusoidal curve fit. This observation lends additional support to the idea that violent human behavior and impulsivity may be directly linked to values of SERT Bmax, which can be affected by various psychoactive drugs and also varies with the natural change of seasons.

[source] Stubborn Reliance on Intuition and Subjectivity in Employee SelectionINDUSTRIAL AND ORGANIZATIONAL PSYCHOLOGY, Issue 3 2008SCOTT HIGHHOUSE The focus of this article is on implicit beliefs that inhibit adoption of selection decision aids (e.g., paper-and-pencil tests, structured interviews, mechanical combination of predictors). Understanding these beliefs is just as important as understanding organizational constraints to the adoption of selection technologies and may be more useful for informing the design of successful interventions. One of these is the implicit belief that it is theoretically possible to achieve near-perfect precision in predicting performance on the job. That is, people have an inherent resistance to analytical approaches to selection because they fail to view selection as probabilistic and subject to error. Another is the implicit belief that prediction of human behavior is improved through experience. This myth of expertise results in an overreliance on intuition and a reluctance to undermine one's own credibility by using a selection decision aid. [source] Formalizing context-based reasoning: A modeling paradigm for representing tactical human behaviorINTERNATIONAL JOURNAL OF INTELLIGENT SYSTEMS, Issue 7 2008Avelino J. Gonzalez This paper formally describes the context-based reasoning (CxBR) paradigm. CxBR can be used to represent tactical human behavior in simulations or in the real world. In problem solving, the context can be said to inherently contain much knowledge about the situation in which the problem is to be solved and/or the environment in which it must be solved. This paper discusses some of the issues involved in a context-driven representation of human behavior and introduces a formal description of CxBR. © 2008 Wiley Periodicals, Inc. [source] Agents that acquire negotiation strategies using a game theoretic learning theoryINTERNATIONAL JOURNAL OF INTELLIGENT SYSTEMS, Issue 1 2006Norberto Eiji Nawa Automated negotiation systems and real-world negotiation situations have many aspects in common. Time is a relevant factor for all parties; information about preferences is private, and there is no interest in having it disclosed; negotiators learn about the opponents and try to enhance their strategies while interacting with one another. Experiments were performed with computational agents employing a learning algorithm based on the ideas of the Experience-Weighted Attraction theory of learning in games, which has been shown to model well human behavior observed in experimental settings. Negotiation strategies are acquired as the agents play bargaining games against one another. The strategies determine the agents' behaviors: how much they offer to the opponent, when they make offers, and the conditions for accepting an offer. The results show that the learning agents were able to acquire sensible strategies even from the most unstructured and dynamic environments. © 2006 Wiley Periodicals, Inc.

Bell Expectations, which are beliefs about a future state of affairs, constitute a basic psychological mechanism that underlies virtually all human behavior. Although expectations serve as a central component in many theories of organizational behavior, they have received limited attention in the organizational justice literature. The goal of this paper is to introduce the concept of justice expectations and explore its implications for understanding applicant perceptions. To conceptualize justice expectations, we draw on research on expectations conducted in multiple disciplines. We discuss the three sources of expectations , direct experience, indirect influences, and other beliefs , and use this typology to identify the likely antecedents of justice expectations in selection contexts. We also discuss the impact of expectations on attitudes, cognitions, and behaviors, focusing specifically on outcomes tied to selection environments. Finally, we explore the theoretical implications of incorporating expectations into research on applicant perceptions and discuss the practical significance of justice expectations in selection contexts. [source] Epistemology of Transformative Material Activity: John Dewey's Pragmatism and Cultural-Historical Activity TheoryJOURNAL FOR THE THEORY OF SOCIAL BEHAVIOUR, Issue 4 2006REIJO MIETTINEN The paper compares John Dewey's pragmatism and cultural-historical activity theory as epistemologies and theories of transformative material activity. For both of the theories, the concept of activity, the prototype of which is work, constitutes a basis for understanding the nature of knowledge and reality. This concept also implies for both theories a methodological approach of studying human behavior in which social experimentation and intervention play a central role. They also suggest that reflection and thought, mediated by language and semiotic artifacts, serve the reorientation of activity and is vital in the development of new, alternative ways of action. That is why Dewyan pragmatism and activity theory supply means of understanding organizational behavior and change in human activities better than the concepts of practice based on rule following, routines or embodied skills. [source] The Limits of Organizational Theory and Incentives (Or, Why Corporate Success Is Not Just About Money)JOURNAL OF APPLIED CORPORATE FINANCE, Issue 4 2005Ronald Schmidt Most economists begin their study of organizational behavior by taking for granted that incentive compensation influences behavior. Managers and employees are assumed to have "utility functions" that reflect a very basic set of "preferences",preferences for things like money and leisure and job security. And, as clearly simplistic as it is, this "model" of human behavior has been shown to have considerable predictive power. But it is equally clear that financial incentives and rewards are not all that matters in motivating people within large organizations. What economists have failed to recognize is the important subjective consequences for employees of acting in accord with well-designed incentives that have been "internalized",viewed not just as leading to financial rewards and corporate success, but as "the right thing to do." In the language of economists, a well-designed incentive program can end up influencing not only people's behavior, but their underlying "preferences," or what non-economists like to call "values." And it is these preferences and values that are at the core of an organization's "culture." [source] Defining psychology: What can it do for us?JOURNAL OF CLINICAL PSYCHOLOGY, Issue 12 2004David A.F.

Specific objections to mentalistic interpretations of behavioral phenomena are detailed, and examples from clinical psychology are used to show the importance of behavioral approaches in applied domains. It is argued that the relation between behavior theory and clinical psychology is critical to the continued advancement of applied psychology.

Ilardi Plaud's (2001) radical behavioral manifesto suggests that a psychological science based exclusively upon the study of environment-behavior functional contingencies would yield a discipline unencumbered by mentalism, vaguely delineated disciplinary boundaries, or inappropriate reductionism. In reply, we note that: (a) mental events,e.g., thoughts and feelings,are increasingly accessible to objective investigation, and provide an observable proximal causal mechanism for the environmental selection of behavior; (b) the call for pristine disciplinary boundaries is anachronistic, inasmuch as progress in the natural sciences has engendered disciplinary boundaries that are increasingly porous; (c) cognitive neuroscience facilitates a comprehensive understanding of complex human behavior by mapping out the relationship between such behavior and underlying brain events, thereby engaging in an appropriate form of reductionism (constitutive reductionism) that has become a hallmark of the natural sciences; and (d) ironically, it is radical behaviorism, in its disavowal of the informational level of complexity instantiated in brain events, that engages in inappropriate eliminative reductionism (i.e., reducing neural information to "nothing but" its underlying bring states). © 2001 Jo n Wiley & Sons, Inc.

Perrachione Advances in neuroimaging technology have led to an explosion in the number of studies investigating the living human brain, and thereby our understanding of its structure and function. With the proliferation of dazzling images from brain scans in both scientific and popular media, researchers from other fields in the social and behavioral sciences have naturally become interested in the application of neuroimaging to their own research. Commercial enterprises have long been interested in the prospects of literally "getting inside the heads" of customers and partners, with a variety of goals in mind. Here we consider the ways in which scholars of consumer behavior may draw upon neuroscientific advances to inform their own research. We describe the motivation of neuroscientific inquiry from the point of view of neuroscientists, including an introduction to the technologies and methodologies available; correspondingly, we consider major questions in consumer behavior that are likely to be of interest to neuroscientists and why. Recent key discoveries in neuroscience are presented which will likely have a direct impact on the development of a neuromarketing subdiscipline and for neuroimaging as a marketing research technique. We discuss where and how neuroscience methodologies may reasonably be added to the research inventory of marketers. In sum, we aim to show not only that a neuromarketing subdiscipline may fruitfully contribute to our understanding of the biological bases of human behavior, but also that developing this as a productive research field will rest largely in framing marketing research questions in the brain-centric mindset of neuroscientists.

(2010) 113, 563,575. Abstract The importance of stress in modifying human behavior and lifestyle is no longer a matter of debate. Although mild stress enhances the immune response and prevents infections, prolonged stress seems to play pathogenic roles in depression and neurodegenerative disorders. The body has developed an adaptive stress response consisting of cardiovascular, metabolic, and psychological changes, which act in concert to eliminate stressors. One of the major components of this response is the hypothalamic,pituitary,adrenal axis, also known as the stress axis. Over the last 30 years, many studies have documented the integrated stress-axis regulation by neurotransmitters. They have also demonstrated that gaseous neuromodulators, such as NO, CO, and H2S, regulate the hypothalamic release of neuropeptides. The specific effects (stimulatory vs. inhibitory) of these gases on the stress axis varies, depending on the type of stress (neurogenic or immuno-inflammatory), its intensity (low or high), and the species studied (rodents or humans). This review examines the complex roles of NO, CO, and H2S in modulation of stress-axis activity, with particular emphasis on the regulatory effects they exert at the hypothalamic level.

Lynne Cooper ABSTRACT This special issue of the Journal of Personality is predicated on the assumption that close relationships provide the central stage for the drama of human experience. This all-important context both shapes and conditions the expression of personality, and thus must play an integral role in any truly adequate account of human behavior. The importance of this agenda is perhaps overshadowed only by its difficulty. Contributions to the present issue, therefore, take stock of past research, highlight current state-of-the-art research, and offer a vision of the next generation of research on personality and close relationships. The conceptual and methodological approaches highlighted in this issue remain faithful to the dynamic, interdependent, and multilayered nature of the processes linking personality and close relationships. [source] Scaling Up Learning Models in Public Good GamesJOURNAL OF PUBLIC ECONOMIC THEORY, Issue 2 2004Jasmina Arifovic We study three learning rules (reinforcement learning (RL), experience weighted attraction learning (EWA), and individual evolutionary learning (IEL)) and how they perform in three different Groves,Ledyard mechanisms. We are interested in how well these learning rules duplicate human behavior in repeated games with a continuum of strategies. We find that RL does not do well, IEL does significantly better, as does EWA, but only if given a small discretized strategy space. We identify four main features a learning rule should have in order to stack up against humans in a minimal competency test: (1) the use of hypotheticals to create history, (2) the ability to focus only on what is important, (3) the ability to forget history when it is no longer important, and (4) the ability to try new things.
