Research on implicit theories suggests that incremental beliefs—that attributes are malleable—can help buffer people against the adverse effects of setbacks on goal achievement. We conducted a longitudinal experiment to examine whether an incremental beliefs intervention could help dieters manage their body weight in the face of severe dieting setbacks. To explore the efficacy of our incremental beliefs intervention, we randomly assigned individuals to a control, a knowledge, or an incremental beliefs condition. In addition to examining the main effect of intervention condition on weight-loss across a 12-week period, we also tested the hypothesis that although participants assigned to the control or knowledge intervention condition would gain more weight as dieting setbacks became more severe, participants assigned to the incremental beliefs condition would not. Results supported this hypothesis: Incremental beliefs protected against setback-related weight-gain. Implications for integrating implicit beliefs interventions with obesity relapse prevention programs are discussed. 相似文献

Why do people behave aggressively toward romantic partners, and what can put the brakes on this aggression? Provocation robustly predicts aggression in both intimate and nonintimate relationships. Four methodologically diverse studies tested the hypothesis that provocation severity and relationship commitment interact to predict aggression toward one's romantic partner, with the aggression-promoting effects of provocation diminishing as relationship commitment increases. Across all four studies, commitment to one's romantic relationship inhibited aggression toward one's partner when individuals were severely (but not mildly) provoked. Study 4 tested the hypothesis that this Partner Provocation × Commitment interaction effect would be strong among individuals high in dispositional tendencies toward retaliation but weak (perhaps even nonexistent) among individuals low in such tendencies. Discussion emphasizes the importance of understanding instigating, impelling, and inhibiting processes in the perpetration of aggression toward intimate partners. 相似文献

Natural selection modified the attachment-behavioral system to bond adult mating partners in early members of the genus Homo, thus facilitating increased investment, especially paternal investment, in offspring. Previously existing adaptations that fostered intersexual conflict (e.g., ovulatory adaptations) could have threatened attachment bonds; therefore, the attachment-behavioral system might have evolved the ability to mute or refocus such adaptations for the purpose of strengthening the bond. Two studies offer support for this prediction. Women who were strongly attached to their romantic partner revealed positive associations of fertility with reports of romantic physical intimacy, but these associations were negative among unbonded women. This moderational effect of attachment bond strength was robust beyond dispositional attachment anxiety and avoidance, relationship satisfaction, relationship commitment, and partner physical attractiveness, none of which revealed robust moderational effects. Findings highlight how researchers can use the timeline of hominid evolution (i.e., phylogeny) as a tool to complement functional, adaptationist hypotheses. 相似文献

The remediation of executive function in patients with schizophrenia is important in rehabilitation because these skills affect the patient's capacity to function in the community. There is evidence that instructional techniques can improve deficits in the Wisconsin Card Sorting Test (WCST) in some schizophrenia patients. We used a standard test/training phase/standard test format of the WCST to classify 36 schizophrenia patients as high-achievers, learners or non-retainers. All healthy controls performed as high-achievers. An event-related fMRI design assessed neural activation patterns during post-training WCST performance. Patients showed a linear trend between set-shifting related activation in the anterior cingulate cortex and learning potential, i.e. increased activation in high-achievers, a trend for increased activation in learners, and no activation in non-retainers compared to controls. In addition, activation in the temporoparietal cortex was highest in patients classified as learners, whereas in non-retainers activation was increased in the inferior frontal gyrus compared to controls and high-achieving patients. These results emphasize the relevance of the ACC's neural integrity in learning set-shifting strategies for patients with schizophrenia. Also, our results support the hypothesis that compensatory neural activation in patients with schizophrenia helps them to catch up with healthy controls on cognitive tasks. 相似文献

Children with early developmental delays are at heightened risk for behavior problems and comorbid psychopathology. This study
examined the trajectories of regulatory capabilities and their potentially mediating role in the development of behavior problems
for children with and without early developmental delays. A sample of 231 children comprised of 137 typically developing children
and 94 children with developmental delays were examined during mildly frustrating laboratory tasks across the preschool period
(ages 3–5). Results indicated that children with delays had greater use of maladaptive strategies (distraction, distress venting)
and lower use of adaptive strategies (constructive coping) than typically developing children. For both groups, strategies
had similar rates of growth across time; maladaptive strategies decreased and adaptive strategies increased. The intercept
of strategy use, but not the slope, was found to mediate the relation between developmental risk and externalizing behaviors.
Findings support that dysregulation, rather than the developmental risk, may be responsible for the high levels of comorbid
psychopathology. 相似文献

When studying online movement adjustments, one of the interesting parameters is their latency. We set out to compare three different methods of determining the latency: the threshold, confidence interval, and extrapolation methods. We simulated sets of movements with different movement times and amplitudes of movement adjustments, all with the same known latency. We applied the three different methods in order to determine when the position, velocity, and acceleration of the adjusted movements started to deviate from the values for unperturbed movements. We did so both for averaged data and for the data of individual trials. We evaluated the methods on the basis of their accuracy and precision, and according to whether the latency was influenced by the intensity of the movement adjustment. The extrapolation method applied to average acceleration data gave the most reliable estimates of latency, according to these criteria. 相似文献

Bisection tasks are used in research on normal space and time perception and to assess the perceptual distortions accompanying neurological disorders. Several variants of the bisection task are used, which often yield inconsistent results, prompting the question of which variant is most dependable and which results are to be trusted. We addressed this question using theoretical and experimental approaches. Theoretical performance in bisection tasks is derived from a general model of psychophysical performance that includes sensory components and decisional processes. The model predicts how performance should differ across variants of the task, even when the sensory component is fixed. To test these predictions, data were collected in a within-subjects study with several variants of a spatial bisection task, including a two-response variant in which observers indicated whether a line was transected to the right or left of the midpoint, a three-response variant (which included the additional option to respond “midpoint”), and a paired-comparison variant of the three-response format. The data supported the model predictions, revealing that estimated bisection points were least dependable with the two-response variant, because this format confounds perceptual and decisional influences. Only the three-response paired-comparison format can separate out these influences. Implications for research in basic and clinical fields are discussed. 相似文献

Luther develops his idea of the grace of God in tandem with his idea of economy, and a society characterized by ethical and social values such as love of neighbor and caring for the weak and poor. Hence, the reformer's search for a gracious God is developed along with his criticism of the current indulgence doctrine and the emerging oeconomia moderna. Thus, building on a simul gratia et oeconomia, Luther's reformation theology can be perceived as the intersection of an economy of grace and a horizontal social economy (works of love) in quotidian life that together constitute human capital. 相似文献
