Pigeons and other animals sometimes deviate from optimal choice behavior when given informative signals for delayed outcomes. For example, when pigeons are given a choice between an alternative that always leads to food after a delay and an alternative that leads to food only half of the time after a delay, preference changes dramatically depending on whether the stimuli during the delays are correlated with (signal) the outcomes or not. With signaled outcomes, pigeons show a much greater preference for the suboptimal alternative than with unsignaled outcomes. Key variables and research findings related to this phenomenon are reviewed, including the effects of durations of the choice and delay periods, probability of reinforcement, and gaps in the signal. We interpret the available evidence as reflecting a preference induced by signals for good news in a context of uncertainty. Other explanations are briefly summarized and compared.  相似文献

Well-being is one of the keys to successful and optimal development across the lifespan. Based on the idea that development involves changes in individuals’ adaptive capacity to meet their needs over time, the changes that occur in the second half of life require effort to adapt to the new reality. This study used a structural model to test the effects of coping strategies and resilience on well-being in a sample of 305 mid-life adults. Several constructs were measured: coping strategies, resilience, and well-being. A final model was obtained with good fit indices; psychological well-being was positively predicted by resilience and negatively by emotional coping. Moreover, positive reappraisal and avoidance form part of both coping strategies (problem-focused and emotion-focused). Considering the characteristics of the model, educational intervention programs could be developed to promote skills that favor good adaptation at this stage in the life cycle and contribute to promoting successful aging.  相似文献

Previous research shows that the experience of familiarity involves the experience of positive affect. In two experiments we clarify and extend this research by showing that the experience of familiarity involves the experience of positive affect even when the nature of the experimental task is non-affective and non-evaluative and even when participants are actively performing other cognitive operations—that the association of familiarity and positive affect is not disrupted by (non-affective and non-evaluative) judgments regardless of whether familiarity does or does not play a role in those judgments. Experiment 1 used a non-affective but evaluative task and Experiment 2 a completely non-evaluative task. Both studies manipulated familiarity through re-exposure and showed that processing familiar stimuli induced a pleasurable subjective experience.  相似文献

The quality of family functioning has been considered an important predictor of adaptation in children with chronic conditions and their parents. Previous research suggests that beyond general family functioning, the specific experience of the family’s condition management is paramount for understanding family members’ adaptation. This study’s first goal was to compare family functioning and parents’ and children’s adaptation outcomes across four chronic conditions: asthma, diabetes, epilepsy, and obesity. Secondly, we explored the mediating role of family life difficulties and parental mutuality, as two potential paths through which family cohesion is linked to family members’ adaptation. A total of 263 parents of children (3–19 years old) with asthma (n = 77), obesity (n = 79), epilepsy (n = 52) and diabetes (n = 55) completed self-report measures of family cohesion, family life difficulty, parental mutuality, anxiety and depressive symptoms, and their children’s health-related quality of life (HrQoL). The results showed that families of children with diabetes, obesity, and epilepsy were at higher risk of experiencing family difficulties and children’s deteriorated HrQoL when compared to families of children with asthma. With regard to the links among study variables, although family cohesion had both a direct and indirect relationship with parental depressive symptoms, its links with parental anxiety symptoms and children’s HrQoL were only indirect, through family life difficulty. These associations were consistent across the four clinical groups. These findings emphasize the relevance of family-centered interventions aimed at promoting family cohesion, parents’ mutuality, and effective coping with the demands of pediatric chronic conditions.  相似文献

Affective evaluations (i.e., evaluations of affectively evocative stimuli) play important roles in many behaviors, including clinically relevant behaviors like disordered eating. Understanding automatic and controlled affective evaluations can enhance prediction and treatment of more deliberate versus more impulsive clinical behaviors, respectively. However, methodological and theoretical shortcomings cloud the implicit affective evaluation literature, particularly as applied in clinical psychology. This article aims to improve the clinical science of implicit and explicit affective evaluation by capitalizing on theoretical and methodological advancements drawn from implicit social cognition. We recommend three key enhancements to the affective evaluation literature: improve the structural comparability between indirect and direct measures, assess evaluations on both valence and arousal dimensions of affect, and carefully characterize and select stimuli. Additional improvements to analytic approaches (e.g., mixed effects modeling and process dissociation) are also recommended. Such efforts will advance our theoretical understanding of the relative contributions of automatic and controlled processes to clinically relevant affective evaluation, thereby informing assessment and improving intervention. Applying advanced methodologies of implicit cognition to clinical phenomena will also reiterate and reinforce the use of these advances in social psychology.  相似文献

Young children, like adults, understand that human agents can flexibly choose different actions in different contexts, and they evaluate these agents based on such choices. However, little is known about children's tendencies to attribute the capacity to choose to robots, despite increased contact with robotic agents. In this paper, we compare 5- to 7-year-old children's and adults’ attributions of free choice to a robot and to a human child by using a series of tasks measuring agency attribution, action prediction, and choice attribution. In morally neutral scenarios, children ascribed similar levels of free choice to the robot and the human, while adults were more likely to ascribe free choice to the human. For morally relevant scenarios, however, both age groups considered the robot's actions to be more constrained than the human's actions. These findings demonstrate that children and adults hold a nuanced understanding of free choice that is sensitive to both the agent type and constraints within a given scenario.  相似文献

To further advance assessment of patient-reported outcomes, the European Organisation of Research and Treatment of Cancer (EORTC) Quality of Life Group has developed computerized adaptive test (CAT) versions of all EORTC Quality of Life Core Questionnaire (QLQ-C30) scales/items. The aim of this study was to develop and evaluate an item bank for CAT measurement of insomnia (CAT-SL). In line with the EORTC guidelines, the developmental process comprised four phases: (I) defining the concept insomnia and literature search, (II) selection and formulation of new items, (III) pre-testing and (IV) field-testing, including psychometric analyses of the final item bank. In phase I, the literature search identified 155 items that were compatible with our conceptualisation of insomnia, including both quantity and quality of sleep. In phase II, following a multistep-approach, this number was reduced to 15 candidate items. Pre-testing of these items in cancer patients (phase III) resulted in an item list of 14 items, which were field-tested among 1094 patients in phase IV. Psychometric evaluations showed that eight items could be retained in a unidimensional model. The final item bank yielded greater measurement precision than the original QLQ-C30 insomnia item. It was estimated that administering two or more items from the insomnia item bank with CAT results in a saving in sample size between approximately 15–25%. The 8-item EORTC CAT-SL item bank facilitates precise and efficient measurement of insomnia as part of the EORTC CAT system of health-related quality life assessment in both clinical research and practice.

Body dissatisfaction is prevalent in young women, and is associated with symptoms of body dysmorphic disorder (BDD) and eating disorders (EDs). The aim of the study was to assess the efficacy of a mobile application, based on cognitive behavioral principles, in reducing body dissatisfaction and BDD/ED symptoms in female university students considered at high-risk of developing body image disorders (BIDs). Fifty university students at high-risk of developing BIDs (using self-report questionnaires assessing BIDs and the Structured Clinical Interview for DSM-5 Clinical Version) were randomized in two groups: immediate-use App group (iApp group; n = 25) and delayed-use App group (dApp group; n = 25). The iApp group started using the app at baseline for 16 days (T0 to T1). The dApp group waited for 16 days before starting to use the app (T1 to T2). Participants completed questionnaires at baseline (T0), 16 days from baseline (T1), and 32 days from baseline (T2). Repeated measure Analyses of Variance (ANOVAs) showed a Group (iApp vs. dApp) × Time (T0 vs. T1) interaction on BDD symptoms indicating medium effect size (partial eta squared) reductions in the iApp group compared to dApp group at T1; post-intervention means for BDD symptoms were under the cut-off for extreme body dissatisfaction/BDD symptoms in both groups. Pertaining to ED symptoms, no significant Group × Time interaction was detected. Training 3 minutes a day for 16 days with a CBT-based mobile application may lead to reductions in some forms of body dissatisfaction, including BDD symptoms in female university students at high-risk of developing BIDs. On the other hand, effects of the intervention on ED symptoms seem more limited.  相似文献
