Motivational Processes (motivational + process)
Selected AbstractsHow changes in job demands and resources predict burnout, work engagement, and sickness absenteeismJOURNAL OF ORGANIZATIONAL BEHAVIOR, Issue 7 2009Wilmar B. Schaufeli The present longitudinal survey among 201 telecom managers supports the Job Demands-Resources (JD-R) model that postulates a health impairment process and a motivational process. As hypothesized, results of structural equation modeling analyses revealed that: (1) increases in job demands (i.e., overload, emotional demands, and work-home interference) and decreases in job resources (i.e., social support, autonomy, opportunities to learn, and feedback) predict burnout, (2) increases in job resources predict work engagement, and (3) burnout (positively) and engagement (negatively) predict registered sickness duration ("involuntary" absence) and frequency ("involuntary" absence), respectively. Finally, consistent with predictions results suggest a positive gain spiral: initial work engagement predicts an increase in job resources, which, in its turn, further increases work engagement.

Drug-induced sensitization has also been linked to increased appetitive responses for non-drug, natural reinforcers. The present research investigated whether ethanol (EtOH)-induced neural changes, inferred from psychomotor sensitization, can modify consumption and intake dynamics for the natural reinforcer, sucrose. The effects of EtOH-induced sensitization in mice on the temporal structure of sucrose intake patterns were measured using a lickometer system. After sensitization, sucrose intake dynamics were measured for 1 hour daily for 7 days and indicated more rapid initial approach and consumption of sucrose in EtOH-sensitized groups; animals showed a shorter latency to the first intake bout and an increased number of sucrose bottle licks during the initial 15 minutes of the 1-hour sessions. This effect was associated with increased frequency and size of bouts. For the total 1-hour session, sucrose intake and bout dynamics were not different between groups, indicating a change in patterns of sucrose intake but not total consumption. When sensitization was prevented by the ,-aminobutyric acid B receptor agonist, baclofen, the increased rate of approach and consumption of sucrose were also prevented. Thus, EtOH-induced sensitization, and not the mere exposure to EtOH, was associated with changes in sucrose intake patterns. These data are consistent with current literature suggesting an enhancing effect of drug-induced sensitization on motivational processes involved in reinforcement. [source] Disruption of self-organized actions in monkeys with progressive MPTP-induced parkinsonism: II.EUROPEAN JOURNAL OF NEUROSCIENCE, Issue 2 2004Effects of reward preference Abstract The motor and cognitive symptoms of Parkinson's disease (PD) are well documented, but little is known about the functionality of motivational processes mediated by the limbic circuits of basal ganglia. The aim of this study was to test the ability of motivational processes to direct and to urge behaviour, in four vervet monkeys (Cercopithecus aethiops) progressively intoxicated with systemic 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP) injections (0.3,0.4 mg/kg every 4,7 days). In the food preference task, the monkeys had to retrieve two types of directly visible food, simultaneously available in the wells of a reward board. At all stages of MPTP-induced parkinsonism, the monkeys continued to take their favourite food first. In the symbol discrimination task, the wells were covered with sliding plaques cued by symbols indicating the absence or presence of a reward, and the different types of food were blocked in separate sessions. Monkeys with mild or moderate parkinsonism made fewer attempts and took longer to retrieve non-preferred compared with preferred rewards. These results indicate that motivational processes are still able to direct (food preference task) and to urge (symbol discrimination task) behaviour in MPTP-lesioned monkeys. Such a functional preservation may be related to the relatively spared dopaminergic innervation of the limbic circuits that we found in our monkeys, in agreement with the literature on humans. Furthermore, the frequency of executive disorders (such as hesitations and freezing) appeared to be much lower with the preferred rewards. Thus, the preserved motivational processes may help to overcome executive dysfunction in the early stages of human PD. [source] Right-wing authoritarianism and social dominance orientation and the dimensions of generalized prejudice: A longitudinal testEUROPEAN JOURNAL OF PERSONALITY, Issue 4 2010Frank Asbrock Abstract A Dual Process Model (DPM) approach to prejudice proposes that there should be at least two dimensions of generalized prejudice relating to outgroup stratification and social perception, which should be differentially predicted by Right-Wing Authoritarianism (RWA) and Social Dominance Orientation (SDO). The current study assessed the causal effects of SDO and RWA on three dimensions of prejudice using a full cross-lagged longitudinal sample (N,=,127). As expected, RWA, but not SDO, predicted prejudice towards ,dangerous' groups, SDO, but not RWA, predicted prejudice towards ,derogated' groups, and both RWA and SDO predicted prejudice towards ,dissident' groups. Results support previously untested causal predictions derived from the DPM and indicate that different forms of prejudice result from different SDO- and RWA-based motivational processes.

[source] Proximity and distance goals in adult attachmentEUROPEAN JOURNAL OF PERSONALITY, Issue 8 2008Marieke Dewitte Abstract We used a variant of the Implicit Association Test (IAT) and explicit reports to examine the assumption that attachment anxiety and avoidance are related to proximity and distance goals. Results confirmed that attachment avoidance was associated with a stronger implicit motivation for and positive evaluation of distance goals in attachment relationships. This was found both at the implicit and explicit levels and both in a threat and non-threat context. Attachment anxiety was associated with proximity goals only when measured explicitly, but not when goal activation was measured implicitly. Our findings highlight the importance of considering both implicit and explicit goal representations when studying motivational processes in the context of attachment, and suggest that the IAT can provide a useful tool for investigating implicit motivational constructs.

[source] Irrational Wanting and Subrational Liking: How Rudimentary Motivational and Affective Processes Shape Preferences and ChoicesPOLITICAL PSYCHOLOGY, Issue 4 2003Piotr Winkielman People's wanting and liking reactions reflect not only high-level beliefs, but also the operation of rudimentary biopsychological processes. Previous studies suggest that the following wanting and liking processes may be relevant to political behavior: irrational wanting (where wanting is triggered by activation of the brain dopamine system and becomes dissociated from liking); unconscious liking and wanting (where evaluative judgments and behavior are modified without awareness of the eliciting affective stimuli or of the underlying affective response); and fluency-based liking (where preferences are influenced by the ease of stimulus processing). This review suggests how conceptual and methodological tools from affective neuroscience and psychophysiology can refine our understanding of basic affective and motivational processes that shape political attitudes and choices. [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] Clinical and imaging evidence of zolpidem effect in hypoxic encephalopathyANNALS OF NEUROLOGY, Issue 1 2007Christine Brefel-Courbon MD We conducted a randomized, double-blind, placebo-controlled, single-patient (N = 1) trial to evaluate the efficacy of zolpidem in a 48-year-old woman with an akinetic mutism. Motor and cognitive examinations and functional imaging were performed. Acute administration of zolpidem markedly improved motor performance and neuropsychological status. Cerebral metabolism (18F-fluorodeoxyglucose positron emission tomography) increased in postrolandic territories and in frontal cortex. Using the H215O positron emission tomography, we found a drug-induced activation in the anterior cingulate and orbitofrontal cortices. Zolpidem induced a transient improvement in motor and cognitive performances. This paradoxical effect could result from an activation of limbic loops modulating motivational processes.
