Critical Questions (critical + question)
Selected AbstractsLearning and re-learning regime support: The dynamics of post-communist regimesEUROPEAN JOURNAL OF POLITICAL RESEARCH, Issue 1 2002William Mishler The political support of citizens of new democracies reflects two sets of experiences. Initially, people are socialized into an undemocratic regime; then, they must re-learn political support in relation to a new regime. In an established democracy, it is difficult to disentangle the effect of early socialization and current performance because both refer to the same regime. However, this is both possible and necessary in countries where there has been a change in regime. Critical questions then arise: When, whether and how do citizens determine their support for their new regime? At the start of a new regime past socialization should be more important but, after a few years, current performance should become more important. We draw on 47 Barometer surveys between 1991 and 1998 in ten more or less democratic post-communist regimes of Central and Eastern Europe and the former Soviet Union to test the relative importance of early socialization influences, the legacy of the communist past, and the political and economic performance of new regimes. We find that economic and political performance explains the most variance in support and, secondarily, the communist legacy. Early socialization is insignificant. However, contrary to economic theories of voting, the impact of political performance is greater than the impact of economic performance in post-communist countries , and its impact is increasing. [source] Linking habitat selection, emigration and population dynamics of freshwater fishes: a synthesis of ideas and approachesECOLOGY OF FRESHWATER FISH, Issue 2 2006T. E. McMahon Abstract,,, The consequences of individual behaviour to dynamics of populations has been a critical question in fish ecology, but linking the two has proven difficult. A modification of Sale's habitat selection model provides a conceptual linkage for relating resource availability and individual habitat selection to exploratory behaviour, emigration and population-level responses. Whole-population experiments with pupfish Cyprinodon macularius that linked all factors along this resource to population continuum lend support to this conceptual model, and illustrate that emigration may be much more common in fish populations than considered in most individual- or population-based models. Accommodating emigration can enhance the ecological appropriateness of behavioural experiments and increase confidence in extrapolation of experimental observations to population-level effects. New experimental designs and advancing technologies offer avenues for assessing population consequences of habitat selection and emigration by individual fish. Emigration often is the key linkage between individual behaviour and population responses, and greater understanding of the underlying factors affecting this often-overlooked demographic parameter could offer new approaches for management and conservation of fishes. [source] Rearing Environment Affects the Brain Size of Guppies: Lab-Reared Guppies have Smaller Brains than Wild-Caught GuppiesETHOLOGY, Issue 2 2009James G. Burns Animals bred for captivity often have smaller brains and behave differently than their wild counterparts. These differences in brain size have been attributed to genetic changes resulting from, for example, inbreeding depression and pleiotropic effects of artificial selection for traits such as docility. A critical question, though, is whether these differences in brain size are due to plastic responses to the environment, not just genetic changes. We observed a large reduction in brain size in first generation, lab-reared female guppies compared with wild-caught ones (19% smaller telencephalon, 17% smaller optic tectum). We then reared first-generation, lab-born guppies in environments varying in spatial complexity and size in an attempt to isolate factors that might increase brain size and change temperament, but no significant differences in phenotype were observed. The results of these experiments show that, although the environmental factors responsible for the effect have not been found, even first generation lab-reared individuals can have smaller brains than wild individuals. [source] Leukocyte extravasation as a target for anti-inflammatory therapy , Which molecule to choose?EXPERIMENTAL DERMATOLOGY, Issue 1 2005W.-H. Boehncke Despite some disappointments during the clinical use of these agents and despite their crippling price tag, the recent incorporation of biologicals that target defined molecular controls of leukocyte extravasation into dermatological and rheumatological practise, consequently, has greatly enriched our therapeutic options for battling major, chronic, inflammatory dermatoses such as psoriasis. However, the , as yet unresolved and still rather controversially discussed , critical question is: Which of the multiple steps that control leukocyte extravasation in the human system really offer the most promising, most pragmatic, and safest molecular targets for therapeutic intervention for which disease entity? The current debate intends to stimulate public and rational debate of this crucial issue, beyond the evident commercial interests that are touched by whatever stand one takes. [source] Brain and behavior interface: Stress and the developing brainINFANT MENTAL HEALTH JOURNAL, Issue 3 2003Megan R. Gunnar Animal studies have shown that mother,infant interactions can have long-term impacts on areas of the brain that regulate fearful behavior and the physiology of stress. Here, the research on human infants and children is reviewed with an eye to whether early experiences have similar effects in our species. Research shows that during the first year, sensitive and responsive caregiving becomes a powerful regulator of emotional behavior and neuroendocrine stress hormone activity in young children. Indeed, quality-of-care effects can be detected for children throughout the preschool years. Reviewed research suggests that temperament affects the likelihood that children will show increases in stress hormones as the quality of their care decreases. Finally, we review the literature on stress hormone activity in children who have been maltreated early in life, and explore the critical question of whether enhancing care later in development can reverse the effects on behavior and neurobiology of early adverse experiences. ©2003 Michigan Association for Infant Mental Health. [source] High Conflict Divorce, Violence, and Abuse: Implications for Custody and Visitation DecisionsJUVENILE AND FAMILY COURT JOURNAL, Issue 4 2003CLARE DALTON ABSTRACT Today, judges are faced with the daunting task of determining the best interests of the child and making appropriate custody awards to that end. The best interests of children becomes a critical question when domestic violence is involved; yet, determining what constitutes domestic violence is often debated. Research is often divided on what constitutes domestic violence. One body of research focuses on conflict, another focuses on domestic violence. What the first group identifies as intense emotional distress and disagreement, the other identifies as abuse. Judges making custody determinations in such cases are faced with the difficult challenge of distinguishing between a divorce with "high conflict" and a domestic violence case with ongoing abuse. This article will summarize the legal, philosophical, and historical understandings of the "high conflict" family and its potential impact on children. It will also provide practical judicial guidelines for making the important distinction between high conflict and domestic violence and subsequently crafting appropriate and safe child custody awards. [source] Déjà Vu all over again: Charter reform fails in St. LouisNATIONAL CIVIC REVIEW, Issue 3 2005Robert A. Cropf Editor's note: There is a lively ongoing debate in this country over the forms of organization and the distribution of powers within local government, especially when it comes to the critical question of mayoral leadership. The following essay is an account of a failed attempt to change St. Louis's city charter. Because the National Civic League's Community Services program played a role in facilitating the discussion leading up to the proposal of charter amendments, we would like to emphasize that as with most essays and reports published in this journal, the analysis and conclusions herein represent the perspectives of the authors, or in some cases the participants they interviewed, and not necessarily those of National Civic League staff. We hope this essay will stimulate further discussion and debate on these critical issues of concern. [source] Solubility properties of human tooth mineral and pathogenesis of dental cariesORAL DISEASES, Issue 5 2004T Aoba Dental research over the last century has advanced our understanding of the etiology and pathogenesis of caries lesions. Increasing knowledge of the dynamic demineralization/remineralization processes has led to the current consensus that bacteria-mediated tooth destruction can be arrested or even to some degree reversed by adopting fluoride and other preventive measures without using restorative materials. Our experimental approach provided new insight into the stoichiometries and solubility properties of human enamel and dentin mineral. The determination of the solubility product constant on the basis of the stoichiometric model (Ca)5·x(Mg)q(Na)u(HPO4)v(CO3)w(PO4)3·y(OH,F)1·z, verifies the difference in their solubility properties, supporting the phase transformation between tooth mineral and calcium phosphates in a wide range of fluid compositions as found in the oral environment. Further refinement of the stoichiometry and solubility parameters is essential to assess quantitatively the driving force for de- and remineralization of enamel and dentin in the oral fluid environment. Prediction of the effects of a combination of inhibitors and accelerator(s) on remineralization kinetics is also required. In order to develop devices efficient for optimizing remineralization in the lesion body, it is a critical question how, and to what extent, fluoride can compensate for the activity of any inhibitors in the mineralizing media. [source] What's behind crashing memories?APPLIED COGNITIVE PSYCHOLOGY, Issue 9 2009Plausibility, belief, memory in reports of having seen non-existent images The present study investigated the precise nature of crashing memory reports: Are they truly memories or are they based on beliefs? We asked 88 individuals whether they had seen non-existent footage of the Pim Fortuyn assassination and conducted thorough post-experimental interviews. Two-thirds of our participants falsely reported having seen the footage, while less than 10% also reported details that they could not have seen. Moreover, plausibility ratings of having seen the images were higher than false belief ratings, which in turn were higher than false memory ratings. After having been fully debriefed, 81% of the participants who reported crashing memories attributed their false report to their lack of a full understanding of the critical question. Another 10% of this subsample stated that they truly remembered the images (i.e. false memories). Thus, only a small subset of crashing memory reports seems to be induced by false beliefs and/or false memories. Copyright © 2009 John Wiley & Sons, Ltd. [source] Maternal cyclin B levels "Chk" the onset of DNA replication checkpoint control in DrosophilaBIOESSAYS, Issue 10 2007Dhananjay Yellajoshyula In many animals, early development of the embryo is characterized by synchronous, biphasic cell divisions. These cell divisions are controlled by maternally inherited proteins and RNAs. A critical question in developmental biology is how the embryo transitions to a later pattern of asynchronous cell divisions and transfers the prior maternal control of development to the zygotic genome. The most-common model regarding how this transition from maternal to zygotic control is regulated posits that this is a consequence of the limitation of maternal gene products, due to their titration during early cell divisions. Here we discuss a recent article by Crest et al.1 that instead proposes that the balance of Cyclin-dependent Kinase 1 and Cyclin B (Cdk1-CycB) activity relative to that of the Drosophila checkpoint kinase Chk1 determines when asynchronous divisions begin.

Hodgson Recent work has celebrated the political potential of ,counter-mapping', that is, mapping against dominant power structures, to further seemingly progressive goals. This article briefly reviews the counter-mapping literature, and compares four counter-mapping projects from Maasai areas in Tanzania to explore some potential pitfalls in such efforts. The cases, which involve community-based initiatives led by a church-based NGO, ecotourism companies, the Tanzanian National Parks Authority, and grassroots pastoralist rights advocacy groups, illustrate the broad range of activities grouped under the heading of counter-mapping. They also present a series of political dilemmas that are typical of many counter-mapping efforts: conflicts inherent in conservation efforts involving territorialization, privatization, integration and indigenization; problems associated with the theory and practice of ,community-level' political engagement; the need to combine mapping efforts with broader legal and political strategies; and critical questions involving the agency of ,external' actors such as conservation and development donors, the state and private business interests. [source] Managing ecosystem services: what do we need to know about their ecology?ECOLOGY LETTERS, Issue 5 2005Claire Kremen Abstract Human domination of the biosphere has greatly altered ecosystems, often overwhelming their capacity to provide ecosystem services critical to our survival. Yet ecological understanding of ecosystem services is quite limited. Previous work maps the supply and demand for services, assesses threats to them, and estimates economic values, but does not measure the underlying role of biodiversity in providing services. In contrast, experimental studies of biodiversity,function examine communities whose structures often differ markedly from those providing services in real landscapes. A bridge is needed between these two approaches. To develop this research agenda, I discuss critical questions and key approaches in four areas: (1) identifying the important ,ecosystem service providers'; (2) determining the various aspects of community structure that influence function in real landscapes, especially compensatory community responses that stabilize function, or non-random extinction sequences that rapidly erode it; (3) assessing key environmental factors influencing provision of services, and (4) measuring the spatio-temporal scale over which providers and services operate. I show how this research agenda can assist in developing environmental policy and natural resource management plans. [source] Assessing human germ-cell mutagenesis in the Postgenome Era: A celebration of the legacy of William Lawson (Bill) Russell,ENVIRONMENTAL AND MOLECULAR MUTAGENESIS, Issue 2 2007Andrew J. Wyrobek Abstract Birth defects, de novo genetic diseases, and chromosomal abnormality syndromes occur in ,5% of all live births, and affected children suffer from a broad range of lifelong health consequences. Despite the social and medical impact of these defects, and the 8 decades of research in animal systems that have identified numerous germ-cell mutagens, no human germ-cell mutagen has been confirmed to date. There is now a growing consensus that the inability to detect human germ-cell mutagens is due to technological limitations in the detection of random mutations rather than biological differences between animal and human susceptibility. A multidisciplinary workshop responding to this challenge convened at The Jackson Laboratory in Bar Harbor, Maine. The purpose of the workshop was to assess the applicability of an emerging repertoire of genomic technologies to studies of human germ-cell mutagenesis. Workshop participants recommended large-scale human germ-cell mutation studies be conducted using samples from donors with high-dose exposures, such as cancer survivors. Within this high-risk cohort, parents and children could be evaluated for heritable changes in (a) DNA sequence and chromosomal structure, (b) repeat sequences and minisatellites, and (c) global gene expression profiles and pathways. Participants also advocated the establishment of a bio-bank of human tissue samples from donors with well-characterized exposure, including medical and reproductive histories. This mutational resource could support large-scale, multiple-endpoint studies. Additional studies could involve the examination of transgenerational effects associated with changes in imprinting and methylation patterns, nucleotide repeats, and mitochondrial DNA mutations. The further development of animal models and the integration of these with human studies are necessary to provide molecular insights into the mechanisms of germ-cell mutations and to identify prevention strategies. Furthermore, scientific specialty groups should be convened to review and prioritize the evidence for germ-cell mutagenicity from common environmental, occupational, medical, and lifestyle exposures. Workshop attendees agreed on the need for a full-scale assault to address key fundamental questions in human germ-cell environmental mutagenesis. These include, but are not limited to, the following: Do human germ-cell mutagens exist? What are the risks to future generations? Are some parents at higher risk than others for acquiring and transmitting germ-cell mutations? Obtaining answers to these, and other critical questions, will require strong support from relevant funding agencies, in addition to the engagement of scientists outside the fields of genomics and germ-cell mutagenesis.

[source] Mate Choice for Genetic Benefits: Time to Put the Pieces TogetherETHOLOGY, Issue 1 2010Attila Hettyey It is thought that mate choice allows individuals to obtain genetic benefits for their offspring, and although many studies have found some support for this hypothesis, several critical questions remain unresolved. One main problem is that empirical studies on mate choice and genetic benefits have been rather piecemeal. Some studies (1) aimed to test how mate choice affects offspring fitness, but have not examined whether the benefits are because of genetic effects. Other studies tested whether mate choice provides (2) additive or (3) non-additive genetic benefits and only a few studies (4) considered these genetic effects together. Finally, some studies (5) examined whether the potential benefits that might be gained from mate choice are due to additive genetic effects vs. non-additive effects, and although they found evidence for both, they did not examine whether mate choice is relevant. Furthermore, previous studies have usually not controlled for non-genetic sources of variation in offspring fitness. Thus, there remain gaping holes in our understanding, and it is the connections among the research approaches that now need more attention. We suggest that studies are needed that measure non-genetic effects, the potential benefits from both additive and non-additive genetic effects, and also determine whether mate choice exploits these potential benefits. Such integrative studies are necessary to put the pieces together and clarify the role of genetic benefits in the evolution of mate choice. [source] Tricks of Festival: Children, Enculturation, and American HalloweenETHOS, Issue 2 2005CINDY DELL CLARK The American children's ritual, Halloween, involves an emergent, active and complex process rather than unidirectional socialization of children by adults. Inversions of meaning are prominent in Halloween through: 1) adult support for inverted, anti-normative themes, and 2) a turnabout by which children gain ascendance through costumed trick-or-treating. Based on interviews with six and seven year old children and their parents, as well as participant observation at Halloween events, Halloween's inversions had different interpretations for adults compared to children. For example the degree and quality of fear associated with Halloween varied between elders and children. Following the traumatic events of September 11, 2001, adult-rendered meanings of Halloween were shown to be unfixed and subject to modification. These findings raise critical questions about simplistic notions of socialization and cultural reduplication. [source] Regulation of T-cell receptor signalling by membrane microdomainsIMMUNOLOGY, Issue 4 2004Tahir M. Razzaq Summary There is now considerable evidence suggesting that the plasma membrane of mammalian cells is compartmentalized by functional lipid raft microdomains. These structures are assemblies of specialized lipids and proteins and have been implicated in diverse biological functions. Analysis of their protein content using proteomics and other methods revealed enrichment of signalling proteins, suggesting a role for these domains in intracellular signalling. In T lymphocytes, structure/function experiments and complementary pharmacological studies have shown that raft microdomains control the localization and function of proteins which are components of signalling pathways regulated by the T-cell antigen receptor (TCR). Based on these studies, a model for TCR phosphorylation in lipid rafts is presented. However, despite substantial progress in the field, critical questions remain. For example, it is unclear if membrane rafts represent a homogeneous population and if their structure is modified upon TCR stimulation. In the future, proteomics and the parallel development of complementary analytical methods will undoubtedly contribute in further delineating the role of lipid rafts in signal transduction mechanisms. [source] The Glory of God in the Theology of Eberhard JüngelINTERNATIONAL JOURNAL OF SYSTEMATIC THEOLOGY, Issue 4 2006CHRISTOPHER HOLMES By describing the attributes as ingredient in God's inner-trinitarian life as expressed in the passion history, Jüngel offers a rich doctrine of God's glory that emphasizes the communicative character of the divine glory inasmuch as God communicates himself to us as he is, and is true to himself in all that he does. However, from a classical Reformed perspective, critical questions are raised with regards to Jüngel's understanding of the communicatio idiomatum, and his singular focus on the suffering and death of Jesus to the neglect of the life of Jesus. [source] Theoretical Model for Conceptualizing Cross-Cultural Applications and Intervention Strategies for Parents of Children With DisabilitiesJOURNAL OF POLICY AND PRACTICE IN INTELLECTUAL DISABILITIES, Issue 4 2006Lorraine Wilgosh Abstract, Theoretical models should provide a framework to facilitate parents' developing effective life management strategies. This paper provides a brief overview of the research on parent effective life management and cross-cultural issues for families with a child who has disabilities. The authors note that the ability of image-making, meaning-making, and choice-making to facilitate outcome is clearly substantiated by research in the stress and coping literature. Using the parent transformational process model, the authors examined responses from 18 multicultural families to demonstrate how this model may go beyond description of relevant cross-cultural family variables in making sense of research findings and conceptualizing meaningful, and appropriate intervention strategies for families of children with disabilities. The authors conclude that rather than a linear process, it is quite likely that the critical questions that parents deal with at the diagnosis of their child reappear at other child and family markers, requiring a reworking of images and meanings and provision of a new range of choices. Professionals should be aware that parental adjustments to disability are not always linear, and thus use this awareness to not judge parents and to serve as catalysts for continued positive life management and transformation throughout the family life cycle. [source] The influence of the interviewing style and the historical context on positioning shifts in the narrative of a Second World War Resistance member1JOURNAL OF SOCIOLINGUISTICS, Issue 2 2009Dorien Van De Mieroop This article involves a study of the narrative of a Second World War Resistance member by means of an interview in which the interviewer explicitly inserts the historical context by selecting the topics for discussion and asking critical questions. The interview deals with three periods: the Wartime period; the First Wave of Reprisals; and the Second Wave of Reprisals. The analyses show that the interviewee's first and second-level positionings shift along with changes in historical period and that they mirror the general historical image of the Resistance. These different positionings are highly consistent in themselves and this consistency is also present on the third level of positioning, because of the interviewee's fairly muted style of narrating, by which blatant inconsistencies are avoided and a general, ,good' identity is constructed. The article also demonstrates that the interview style adds another, important dimension to the analysis of identities in life stories. [source] PHILOSOPHERS OF INTELLECTUAL DISABILITY: A TAXONOMYMETAPHILOSOPHY, Issue 3-4 2009LICIA CARLSON Abstract: This essay explores various roles that philosophers occupy in relation to intellectual disability. In examining how philosophers define their object of inquiry as experts and gatekeepers, it raises critical questions concerning the nature of philosophical discourse about intellectual disability. It then goes on to consider three alternate positions, the advocate or friend, the animal, and the "intellectually disabled," each of which points to new ways of philosophizing in the face of intellectual disability. [source] CONCILIAR, NOT CONCILIATORY: HANS URS VON BALTHASAR'S ECCLESIOLOGICAL SYNTHESIS OF VATICAN IIMODERN THEOLOGY, Issue 1 2008STEFFEN LÖSEL In this essay, I analyze von Balthasar's ecclesiology against the backdrop of Vatican II and identify its ecumenical challenges. I demonstrate how von Balthasar's ecclesiology reflects the last council particularly in terms of its integration of ecclesiology and mariology, its gendered conceptualization of the church and its hierarchy, and its reaffirmation of papal primacy. From a Protestant perspective, I have, however, a number of critical questions. First, I question von Balthasar's sacred sociology, which ultimately privileges the magisterium as the decisive source of divine revelation. Second, I point out the peculiarities of von Balthasar's typological interpretation of scripture and its consequences for his ecclesiological vision. Finally, I take issue with his outdated binary gender anthropology. [source] Susceptibility genes in movement disordersMOVEMENT DISORDERS, Issue 7 2008Sonja Scholz MD Abstract During the last years, remarkable progress in our understanding of molecular genetic mechanisms underlying movement disorders has been achieved. The successes of linkage studies, followed by positional cloning, have dominated the last decade and several genes underlying monogenic disorders have been discovered. The pathobiological understanding garnered from these mutations has laid the foundation for much of the search for genetic loci that confer risk for, rather than cause, disease. With the introduction of whole genome association studies as a novel tool to investigate genetic variation underlying common, complex diseases, a new era in neurogenomics has just begun. As the field rapidly moves forward several new challenges and critical questions in clinical care have to be addressed. In this review, we summarize recent advances in the discovery of susceptibility loci underlying major movement disorders, explain the newest methodologies and tools employed for finding and characterizing genes and discuss how insights into the molecular genetic basis of neurological disorders will impact therapeutic concepts in patient care. © 2008 Movement Disorder Society [source] A conversation on diverse perspectives of spirituality in nursing literatureNURSING PHILOSOPHY, Issue 2 2008Barbara Pesut PhD RN Abstract, Spirituality has long been considered a dimension of holistic palliative care. However, conceptualizations of spirituality are in transition in the nursing literature. No longer rooted within religion, spirituality is increasingly being defined by the universal search for meaning, connectedness, energy, and transcendence. To be human is to be spiritual. Some have argued that the concept of spirituality in the nursing literature has become so generic that it is no longer meaningful. A conceptualization that attempts to be all-encompassing of what it means to live a human life has a tendency to render invisible the differences that make life meaningful. For palliative patients in particular, a generic approach may obscure and relativize the important values and beliefs that inform the critical questions that many patients grapple with at end of life. A different approach to conceptualizing spirituality can be achieved through the use of typologies. Rather than obscuring difference, categories are constructed to illuminate how spirituality is understood within a diverse society and how those understandings might influence patient,provider relationships. What follows in this article is a dialogue illustrating one typology of spirituality constructed from a review of selected nursing literature. The hypothetical narrator and three participants, representing the positions of theism, monism, and humanism, discuss their understandings of spirituality and religion, and how those understandings influence the intersections between nursing ontology, epistemology, and spiritual care. [source] Policy Design and the Acceptability of Environmental Risks: Nuclear Waste Disposal in Canada and the United StatesPOLICY STUDIES JOURNAL, Issue 1 2000Michael E. Kraft This article examines the controversial process of developing high-level nuclear waste disposal policy in Canada, with some comparison to experience in the United States. It argues that a policy design perspective can assist in understanding the difficult social and political issues associated with waste disposal and the environmental and health risks that it poses. I examine several critical questions related to such an endeavor and link them to long-term goals of building a sustainable society. Success in formulating and implementing a nuclear waste policy in Canada will depend on the nation's capacity to create requisite processes of public participation. Particularly important are those actions that can help the public understand and assess environmental risks, including related ethical and social issues, and build public trust and confidence in the siting processes and the implementing agencies. [source] Land Transitions in the Tropics: Going Beyond the Case StudiesBIOTROPICA, Issue 1 2010María Uriarte ABSTRACT Estimates of the percent of Earth's land surface that has either been transformed or degraded by human activity range between 39 and 50 percent, with agriculture accounting for the vast majority of these changes. Although much of the focus of research on land use and cover change in the tropics has been on deforestation, ongoing socioeconomic changes both locally and globally have made land transitions in the tropics extremely fluid. In addition, feedbacks between land cover change and human behavior constrain the extent and trajectories of land transitions. The sustainability of land use systems in the tropics depends on an understanding of coupled human,natural systems that can lead to general frameworks for management and prediction. The unprecedented availability of land use/cover data together with ecological data collected at large spatial scales offer exciting opportunities for advancing our understanding of socioecological systems. We rely on six studies of land transitions in the tropics to illustrate some promising approaches and pose critical questions to guide this body of research. [source] False and Recovered Memories in the Laboratory and Clinic: A Review of Experimental and Clinical EvidenceCLINICAL PSYCHOLOGY: SCIENCE AND PRACTICE, Issue 1 2004David H. Gleaves We review the clinical and laboratory evidence for recovered and false memories. Available data suggest that, at least under certain circumstances, both false and recovered memories may occur. We suggest that the critical questions are: (a) how common is each type of memory phenomenon, (b) what factors lead to the occurrence of each (including under what conditions are each possible and/or likely to occur), and perhaps most importantly, (c) can these two types of memories be distinguished from each other? We describe laboratory analogues for both types of experiences and describe an empirical research protocol that can not only demonstrate both phenomena but also compare the two. Such comparisons can help to determine the causes of these phenomena, discover factors that influence the two, and hopefully reveal signature variables that could provide telltale signs differentiating false and recovered memories.
