The ability to make advantageous decisions in the face of uncertainty is an essential human skill, yet the development of such abilities over the lifespan is still not well understood. In the current study, from childhood through older adulthood, we tracked the developmental trajectory of risk taking for gains and losses, and expected value (EV) sensitivity in risky choices. In the gain domain, risk‐taking decreased consistently across the lifespan. In the loss domain, risk‐taking was relatively constant across ages, a result we attribute to the pervasiveness of loss aversion. EV sensitivity showed an inverted‐U‐shaped function, increasing from childhood to adulthood but then decreasing for the elderly, which occurred for both risky gains and risky losses. This finding is consistent with neuropsychological and neuroanatomical evidence concerning the role of the frontal lobe in decision making, which is relatively late to develop during childhood but may degrade earlier in the later years.

This qualitative study was nested within a trial of cognitive behaviour therapy (CBT) and supportive listening for patients with multiple sclerosis (MS). It aimed to enrich understanding of the changes made during therapy and to explore processes of change. In-depth interviews with 30 participants from the treatment trial were analysed inductively and five main themes were developed. The benefits that participants described experiencing as a result of the interventions were highly variable, idiosyncratic and often departed from outcomes measured within the trial. Tuning into and sharing one’s thoughts and feelings and learning specific strategies for living with MS appeared to be important processes for change, and participants identified the latter as particularly important for sustaining long-term benefits from therapy. Whether participants fully engaged with the interventions appeared to be related to their perceptions of being the right sort of candidate for the intervention, their expectations and motivations, the therapeutic relationship, adequate tailoring of the intervention, and practical issues. This study builds on previous research on factors and processes involved in adjustment to MS, the benefits of CBT for this population and highlights important issues to consider when developing psychosocial interventions for people with MS.  相似文献

Recently, there has been much theoretical and applied interest in the prospects of cognitive training for improving cognition. NeuroTracker is a relatively recent training device for improving dynamic attention in athletes by training 3D multiple-object tracking skills. We examined its effectiveness for improving working memory (WM) span in members of the Canadian Armed Forces (CAF) by randomly assigning participants to the experimental (NeuroTracker), active control (adaptive dual n-back task), or passive control (no contact) conditions. NeuroTracker training resulted in significant gains in verbal, visual, and matrix span. No gain was observed in the active or passive control group. These results suggest that NeuroTracker could be a useful training tool for increasing WM span in military samples. Future studies could examine the effects of NeuroTracker training on militarily relevant performance measures that draw on WM span.  相似文献

Investigated were relations among executive cognitive function (ECF), food intake, and physical activity in 184, fourth grade children. It was hypothesized that self-reported ECF proficiency would predict greater self-reported fruit/vegetable intake and physical activity, but less “snack food” intake. Structural models demonstrated that ECF was significantly correlated with less concurrent snack food intake and greater concurrent fruit/vegetable intake, but not physical activity. Baseline ECF also significantly predicted greater fruit/vegetable intake and physical activity four months later, but not snack food intake. One implication is to promote ECF as a correlate and predictor of food intake and physical activity in children by providing opportunities for youth to practice newly developing ECF capacities.  相似文献

We compared the punitiveness of two groups following a manipulation in which participants were either able to cheat on a simple number-matching task, by taking more money then they rightfully earned, or prevented from doing so on the same task. After completing the task, participants read a number of small vignettes of politicians who had acted questionably, and then were asked to rate the scenarios on both how wrong the behavior was and how much punishment it deserved. Participants given the opportunity to cheat with impunity were significantly less punitive when judging questionable behavior on the part of elected officials.  相似文献

Blur detection is affected by retinal eccentricity, but is it also affected by attentional resources? Research showing effects of selective attention on acuity and contrast sensitivity suggests that allocating attention should increase blur detection. However, research showing that blur affects selection of saccade targets suggests that blur detection may be pre-attentive. To investigate this question, we carried out experiments in which viewers detected blur in real-world scenes under varying levels of cognitive load manipulated by the N-back task. We used adaptive threshold estimation to measure blur detection thresholds at 0°, 3°, 6°, and 9° eccentricity. Participants carried out blur detection as a single task, a single task with to-be-ignored letters, or an N-back task with four levels of cognitive load (0, 1, 2, or 3-back). In Experiment 1, blur was presented gaze-contingently for occasional single eye fixations while participants viewed scenes in preparation for an easy picture recognition memory task, and the N-back stimuli were presented auditorily. The results for three participants showed a large effect of retinal eccentricity on blur thresholds, significant effects of N-back level on N-back performance, scene recognition memory, and gaze dispersion, but no effect of N-back level on blur thresholds. In Experiment 2, we replicated Experiment 1 but presented the images tachistoscopically for 200 ms (half with, half without blur), to determine whether gaze-contingent blur presentation in Experiment 1 had produced attentional capture by blur onset during a fixation, thus eliminating any effect of cognitive load on blur detection. The results with three new participants replicated those of Experiment 1, indicating that the use of gaze-contingent blur presentation could not explain the lack of effect of cognitive load on blur detection. Thus, apparently blur detection in real-world scene images is unaffected by attentional resources, as manipulated by the cognitive load produced by the N-back task.  相似文献

Aim: Cognitive errors (CE) and coping strategies (CS) can bear weight on how individuals relate to others and perceive interpersonal relationships. However, there is little research into how clients' erroneous beliefs and maladaptive coping strategies can interfere with the therapeutic process. This study utilised a sample of healthy clients to explore the relationship between their CEs and CSs and their evaluation of therapy. Method: Therapy sessions of undergraduate student clients (N =26) were rated using the Cognitive Error Rating Scale (CERS – 3rd edition), the Coping Patterns Rating Scale (CPRS;), the Session Evaluation Questionnaire (SEQ) and the Session Impact Scale (SIS). Results: Clients who engaged in dichotomous thinking endorsed problem solving less and were more likely to feel unsupported and misunderstood by the therapist. Clients who discounted the positive tended to feel more pressured and judged by therapists. Conversely, those who engaged in problem solving were more likely to find sessions deeper and more valuable as compared to those who reacted to stressful events by submission, escape, or opposition. Implications: Better understanding how and when a client's cognitive errors and coping mechanisms are at play during therapy can help clinicians to address them and intervene appropriately.  相似文献

A body of laboratory work is reviewed suggesting that auditory distraction comes in two functionally distinct forms. Interference‐by‐process is produced when the involuntary processing of the sound competes with a similar process applied deliberately to perform a focal task. In contrast, attentional capture is produced when the sound causes a disengagement of attention away from the prevailing task, regardless of the task processes involved. Particular attention is devoted to reviewing a range of converging evidence from both experimental and individual‐ and group‐differences‐based research, indicating that auditory attentional capture is controllable via greater top‐down task engagement whereas interference‐by‐process is not.  相似文献

Abstract

Recent research has highlighted the central role of disgust in the etiology and maintenance of contamination aversion (CA). Data would also suggest that, although amendable to the treatment of choice for CA (exposure and response prevention [ERP]), disgust is resistant to habituation. However, with regard to CA, it is not yet known if disgust's resistance to habituation is an artifact of the emotion or the disorder. Specifically, research has not yet indicated if severity of CA moderates the effect of ERP on disgust. Utilizing an undergraduate convenience sample (n=33), the present study compared emotional responding (disgust and fear) with repeated exposure to a disgusting contamination-relevant stimulus between participants who are high in contamination aversion (HCA; n=17) and low in contamination aversion (LCA; n=16). Results indicated that, habituation of disgust was slower than fear within the HCA group but not the LCA group. Contrasts revealed that the decay of fear across trials was faster for HCA participants when compared with LCA participants, although decay of disgust was similar between groups. These results indicate that habituation of disgust is slower than fear when elevated CA is present.  相似文献

Abstract

Evidence suggests that the State Trait Inventory for Cognitive and Somatic Anxiety (STICSA) may be a more pure measure of anxiety than other commonly used scales. Further, the STICSA has excellent psychometric properties in both clinical and nonclinical samples. The present study aimed to extend the utility of the STICSA – Trait version by identifying a cut-off score that could differentiate a group of clinically diagnosed anxiety disorder patients (n=398) from a group of student controls (n =439). Two receiver operating characteristic curve analyses indicated cut-off scores of 43 (sensitivity=.73, specificity=.74, classification accuracy=.74) and 40 (sensitivity=.80, specificity=.67, classification accuracy=.73), respectively. In a large community sample (n =6685), a score of 43 identified 11.5% of individuals as probable cases of clinical anxiety, while a score of 40 identified 17.0% of individuals as probable cases of clinical anxiety. As a result of differences in sensitivity and specificity, the present findings suggest a cut-off score of 43 is optimal to identify probable cases of clinical anxiety, while a cut-off score of 40 is optimal to screen for the possible presence of anxiety disorders.  相似文献
