ABSTRACT There is mixed evidence on the impact of delay task difficulty on prospective memory (PM) performance and little research has examined this among older adults. The present study examined younger (N = 60) and older (N = 57) adults’ prospective memory (PM) performance after completing an easy or difficult Raven’s matrices task. To assess whether delay difficulty impacted how often participants thought about their PM intention, participants were asked to report on what they thought about during the delay task itself and retrospectively after all tasks were completed. Younger adults outperformed older adults on the PM task; however, delay task difficulty had no impact PM for either age group. Reports of thinking about the intention during the delay task differed by age group depending whether they were online or retrospective, however, overall greater reports of thinking about the intention was positively associated with PM performance. 相似文献

Behavioral momentum theory (BMT) provides a theoretical and methodological framework for understanding how differentially maintained operant responding resists disruption. A common way to test operant resistance involves contingencies with suppressive effects, such as extinction or prefeeding. Other contingencies with known suppressive effects, such as response-cost procedures arranged as point-loss or increases in response force, remain untested as disruptive events within the BMT framework. In the present set of three experiments, responding of humans was maintained by point accumulation programmed according to a multiple variable-interval (VI) VI schedule with different reinforcement rates in either of two components. Subsequently, subtracting a point following each response (Experiment 1) or increasing the force required for the response to be registered (Experiments 2 and 3 decreased response rates, but responding was less disrupted in the component associated with the higher reinforcement rate. The point-loss contingency and increased response force similarly affected response rates by suppressing responding and human persistence, replicating previous findings with humans and nonhuman animals when other types of disruptive events (e.g., extinction and prefeeding) were investigated. The present findings moreover extend the generality of the effects of reinforcement rate on persistence, and thus BMT, extending the analysis of resistance to two well-known manipulations used to reduce responding in the experimental analysis of behavior. 相似文献

Randomised controlled studies in research environments have demonstrated dialectical behaviour therapy (DBT) to be more efficacious than treatment as usual in reducing suicidal behaviour in patients with borderline personality disorder (BPD). Limited evidence exists for the effectiveness of DBT in the treatment of BPD within routine clinical settings. This study examines the clinical and cost effectiveness of providing DBT over treatment as usual in a routine Australian public mental health service. Forty-three adult patients with BPD were provided with outpatient DBT for six months with patient outcomes compared to those obtained from patients in a wait list group receiving treatment as usual (TAU) from the same service. After six months of treatment the DBT group showed significantly greater reductions in suicidal/non-suicidal self-injury, emergency department visits, psychiatric admissions and bed days. Self-report measures were administered to a reduced sample of patients. With this group, DBT patients demonstrated significantly improved depression, anxiety and general symptom severity scores compared to TAU at six months. Average treatment costs were significantly lower for those patients in DBT than those receiving TAU. Therapists who received intensive DBT training were shown to produce significantly greater improvements in patients’ suicidal and non-suicidal self-injury than therapists who received only 4 day basic training. Further clinical improvements were achieved in patients offered an additional six months of DBT. This study demonstrates that providing DBT to patients within routine public mental health settings can be both clinically effective and cost effective. 相似文献

Alexithymia is a personality trait associated with the reduced ability to regulate, identify, and communicate feelings or
emotions and is often linked to psychosomatic disorders. The present study used event-related potentials (ERPs) to investigate
the relationship between individual differences in alexithymia and emotion regulation. Participants classified as scoring
either high or low on the revised form of the Toronto Alexithymia Scale (TAS-20; Taylor, Bagby, & Parker Psychother Psychosom
57:34–41, 1992) were asked to view negative and neutral images, adopting three different regulation strategies (expressive suppression,
cognitive reappraisal, and attend) while ERPs were recorded. Results revealed an inverse relationship between TAS scores and
emotion-related ERP activity during suppression, but not during reappraisal or a control “attend” condition. These results
were observed in both early and late ERP latencies. These findings are interpreted according to potential differences between
high- and low-TAS individuals regarding the frequency of prior utilization of suppression-based regulation strategies. 相似文献

We examined whether faces differing in attractiveness elicit positive and negative affect in 7- to 10-year-old children (N=66) and adults (N=73). Facial electromyography measured affective response. Less attractive faces evoked significantly more levator labii superioris responses in adults and children. Attractiveness was negatively correlated with corrugator supercilii activity in adults, but not significantly in children. These results suggest that less attractive faces evoke greater disgust and negative affect than more attractive faces. Perceivers' affective reactions to attractive faces may play an important role in attractiveness preferences and attractiveness stereotypes. 相似文献

Display elements were sequentially painted upon a display scope in regular and irregular spatial-temporal orders. The primary result of Mayzner, Tresselt, and their associates is confirmed: within specified temporal-spatial limits, display elements may be perceptually blanked. Characteristics of perceptually blanked elements can, however, be revealed by forced-choice testing. The accuracy of tilt discrimination for perceptually blanked elements is equal to, or better than, that for nonblanked elements. Perceptually blanked elements can also be distinguished from absent and from partially absent elements, presumably on the basis of a crude brightness discrimination. Sequential blanking effects as revealed in the accuracy of slant detection, are not critically dependent upon the magnitude of uniform spacing between the display elements. 相似文献

Male house mice attack their familiar cagemates less than novel intruders-an effect often attributed to habituation of aggression toward odors emanating from the cagemate. This interpretation is overly simplistic in that the effects of familiarizing preexposure depend additionally upon two factors. One factor is the aggression-inhibiting odors emanating from the test male that are deposited onto the cagemate by cohabitation. Supporting evidence is that attack inhibition to the cagemate failed to generalize to noncohabiting same-strain intruders and that eliminating physical contact between subject and cagemate during preexposure prevented the usual postexposure decline in aggression. The second factor is nonolfactory social stimuli emanating from the cagemate during aggressive encounters. The same intruder odors that elicited aggression when placed on a socially active mouse elicited only investigation when placed on models. When subjects were preexposed to an intruder's odor while prevented from socially interacting with the intruder, this investigation subsequently declined while aggression paradoxically increased. 相似文献

Six experiments that were designed to test the adequacy of criterion bias explanations of the word frequency effect and the semantic priming effect are reported. It was found that criterion bias models correctly predicted higher error rates in a lexical decision task for nonwords that were misspelled versions of high-frequency words (e.g., MOHTER), rather than low-frequency words (e.g., BOHTER). Also correct was the prediction of increased error rates for misspelled words preceded by a semantically related word (e.g., NURSE-DOTCOR). However, in a misspelling decision task (in which the subject must decide whether the stimulus is a word, a misspelled word, or a nonword), it can be argued that criterion bias should be inoperative, since correct responses must be delayed until all orthographic information has been checked; this should eliminate both frequency and semantic priming effects. This was found not to be the case; clear frequency and priming effects were obtained for both words and misspelled words. 相似文献
