An evolutionary framework was used to develop a model of relational functioning among friends. The proposed model focuses on the collaborative nature of close friendships and attempts to highlight two adaptive mechanisms important in creating non‐zero‐sum outcomes among highly interdependent parties. The model emphasizes the importance of reciprocity in creating mutually beneficial outcomes through social exchange, and it articulates how the preference for similarity is useful when creating non‐zero‐sum rewards through synergistic coordination. In particular, the focus is on the unique role that shared interests and mutual knowledge play when individuals attempt to pursue common goals through joint activity. The implications of the model are discussed with respect to a host of issues ranging from deceptive communication to relational satisfaction and commitment.  相似文献

Children and adults were tested on a forced‐choice face recognition task in which the direction of eye gaze was manipulated over the course of the initial presentation and subsequent test phase of the experiment. To establish the effects of gaze direction on the encoding process, participants were presented with to‐be‐studied faces displaying either direct or deviated gaze (i.e. encoding manipulation). At test, all the faces depicted persons with their eyes closed. To investigate the effects of gaze direction on the efficiency of the retrieval process, a second condition (i.e. retrieval manipulation) was run in which target faces were presented initially with eyes closed and tested with either direct or deviated gaze. The results revealed the encoding advantages enjoyed by faces with direct gaze was present for both children and adults. Faces with direct gaze were also recognized better than faces with deviated gaze at retrieval, although this effect was most pronounced for adults. Finally, the advantage for direct gaze over deviated gaze at encoding was greater than the advantage for direct gaze over deviated gaze at retrieval. We consider the theoretical implications of these findings.  相似文献

Little is known about the actions supporting exploration and their relation to subsequent actions in situations when participants are surrounded by opportunities for action. Here, the movements that support visual exploration were related to performance in an enveloping football (soccer) passing task. Head movements of experienced football players were quantified with inertial measurement units. In a simulated football scenario, participants completed a receiving–passing task that required them to indicate pass direction to one of four surrounding targets, as quickly as they could after they gained simulated ball possession. The frequency of head movements before and after gaining ball possession and the pass response times were recorded. We controlled exploration time—the time before gaining simulated ball possession—to be 1, 2, or 3?seconds. Exploration time significantly influenced the frequency of head movements, and a higher frequency of head turns before gaining ball possession resulted in faster pass responses. Exploratory action influenced subsequent performatory action. That is, higher frequencies of head movements resulted in faster decisions. Implications for research and practice are discussed.  相似文献

Researchers can study complex developmental phenomena with all the inherent noise and complexity or simplify behaviors to hone in on the essential aspects of a phenomenon. We used the development of walking as a model system to compare the costs and benefits of simplifying a complex, noisy behavior. Traditionally, researchers simplify infant walking by recording gait measures as infants take continuous, forward steps along straight paths. Here, we compared the traditional straight‐path task with spontaneous walking during 20 minutes of free play in 97 infants (10.75–19.99 months of age). We recorded infants’ footfalls on an instrumented floor to calculate gait measures in the straight‐path and free‐play tasks. In addition, we scored videos for other critical aspects of spontaneous walking—steps per bout, shape of walking path, and step direction. Studying infant walking during free play incurred no cost compared with the straight‐path task, but considerable benefits. Straight‐path gait was highly correlated with spontaneous gait and both sets of measures improved with walking age, validating use of the straight‐path task as an index of development. However, a large proportion of free‐play bouts were too short to permit standard gait measures, and most bouts were curved with omnidirectional steps. The high prevalence of these “non‐canonical” bouts was constant over development. We propose that a focus on spontaneous walking, the phenomenon we ostensibly wish to explain, yields important insights into the problems infants solve while learning to walk. Other areas of developmental research may also benefit from retaining the complexity of complex phenomena.  相似文献

The COVID-19 pandemic has been a major source of professional and personal disruption and has had both direct and downstream consequences on almost every aspect of peoples' lives, including their personal goal pursuits. In the face of unexpected hardships and obstacles, people have had to find new paths to goal achievement. In the present work, we examined whether difficulty adjusting goal pursuit during the global disruption of the COVID-19 pandemic is related to negative affective, cognitive, and behavioral goal-related outcomes. Across two studies, we found that people who had more difficulty adjusting their goal pursuit during the pandemic experienced more negative feelings toward their goals, were less satisfied with the status of their goals, and were less likely to actually achieve their goals. Moreover, individual differences in planning tendencies, need for predictability, general adaptability, and perceived pandemic disruption were related to more difficulty adjusting goal pursuit. This work demonstrates the importance of flexibility in the face of setbacks and obstacles, especially during times of disruption and uncertainty.  相似文献

Two cohorts of public elementary school children and their parents (assessed 3 years apart) completed child and parent forms of the Children's Depression Inventory (CDI) and the Revised Children's Manifest Anxiety Scale (RCMAS). Assessments were conducted twice, once during the fall (N = 562) and again during the spring (N = 630) of the 6th grade. Factor analyses revealed 3 factors for each measure. Two of the 3 parent CDI factors manifested some degree of congruence with their counterparts from the child CDI. Similarly, 2 of the 3 RCMAS factors were somewhat congruent across informant types. Differences between parent and child factor structures suggest that parents' and children's reports focus on somewhat different aspects of child psychopathology, and they can make qualitatively different contributions to the multiaxial assessment of children.  相似文献

Although pediatric hospitals specialize in providing care to children and adolescents, at The Children’s Hospital of Philadelphia (CHOP), our team has been providing behavioral health services for two unique parent populations—parents with a child in the Newborn Infant Intensive Care Unit and pregnant women carrying fetuses with specific birth defects and receiving prenatal care in the Center for Fetal Diagnosis and Treatment. A new training program was developed to expand the scope of pediatric psychologists’ practice to include perinatal behavioral health services, specifically for these two unique parent populations served at CHOP. The program includes direct service provision for adult mental health concerns, as well as education and support to help families cope with the existing medical conditions. This article describes the training program and its implementation as a model of training for other pediatric hospitals. The roles of psychologists embedded in these units and hospital privileges are discussed.  相似文献

With the death of Athanasios Koukopoulos last year, psychiatry lost one of its most stimulating and scientifically influential representatives has been lost. His main scientific contributions are in the course of manic depressive illnesses and mixed affective states. Perhaps his most important contribution to modern psychiatry are his studies on the use of antidepressants in bipolar disorder. He was able to show that antidepressants attenuate the beneficial effects of lithium, can trigger mania, and can lead to cycle acceleration and rapid cycling.  相似文献

Previous theory and research suggest that childhood experiences are more likely to generate depressive self-schemas when they focus attention on negative information about oneself, generate strong negative affect, and are repetitive or chronic. Persistent peer victimization meets these criteria. In the current study, 214 youths (112 females) with empirically-validated histories of high or low peer victimization completed self-report measures of negative and positive self-cognitions as well as incidental recall and recognition tests following a self-referent encoding task. Results supported the hypothesis that depressive self-schemas are associated with peer victimization. Specifically, peer victimization was associated with stronger negative self-cognitions, weaker positive self-cognitions, and an elimination of the normative memorial bias for recall of positive self-referential words. Effects were stronger for relational and verbal victimization compared to physical victimization. Support accrues to a model about the social-developmental origins of cognitive diatheses for depression.  相似文献
