This study examined how the amount of effort required to produce a reinforcer influenced subsequent preference for, and strength of, that reinforcer in 7 individuals with intellectual disabilities. Preference assessments identified four moderately preferred stimuli for each participant, and progressive-ratio (PR) analyses indexed reinforcer strength. Stimuli were then assigned to one of four conditions for 4 weeks: fixed-ratio (FR) 1 schedule, escalating FR schedule, yoked noncontingent (NCR) delivery, and restricted access. Preference assessments and PR schedules were then repeated to examine changes in selection percentages and PR break points. Selection percentages decreased for all NCR stimuli but increased for most of the restricted stimuli. There were no systematic changes in selection percentages for either of the contingent stimuli. Break points increased, on average, for all conditions, but the increase was highest for the restricted stimuli and lowest for the NCR stimuli. These results are discussed in relation to recent basic research addressing the influence of effort on stimulus value.  相似文献

Purpose  

Several studies have shown that the traditional stereotype of a “good” manager being masculine and male still exists. The recent changes in the proportion of women and female managers in organizations could affect these two managerial stereotypes, leading to a stronger preference for feminine characteristics and female leaders. This study examines if the gender of an employee, the gender of the manager, and the management gender ratio in an organization are related to employees’ managerial stereotypes.  相似文献

Retrieval-induced forgetting (RIF) refers to the finding that retrieval of a subset of previously studied material can cause forgetting of related unpractised material. Prior work on the role of delay between practice and test for RIF reported mixed results. Whereas some studies found RIF to be a relatively transient phenomenon, others found RIF to persist over time. We examined whether the persistence of RIF can depend on whether wakefulness or sleep follows retrieval practice. We employed a variant of the retrieval-practice paradigm with short (20 minutes) and long (12 hours) delay conditions. In all conditions participants studied a perceptually categorised list followed by retrieval practice on some of the items from some of the categories. Participants studied and practised the material in the morning or the evening. RIF was present in the short-delay conditions, and it was present in the long-delay condition if the delay included nocturnal sleep; if the long delay was filled with diurnal wakefulness, RIF was absent. Results show that whether delay eliminates RIF or not can depend on whether sleep or wake follows retrieval practice. Connections of the results to recent findings about the role of delay and sleep for RIF are discussed.  相似文献

The primary objective of this investigation was to examine the joint influences of intention strength, executive control resources (ECRs) and implementation intentions on physical activity performance in differentially supportive environmental conditions. In two studies, participants were randomly assigned to implementation intentions or control conditions. Individual differences in ECRs, intention strength and physical activity behavior were measured at baseline in the laboratory; follow-up physical activity was measured via an online questionnaire 7 days after the baseline laboratory session. Study 1 was conducted under activity-supportive environmental conditions (i.e., warm weather, little precipitation), whereas Study 2 was conducted under non-supportive environmental conditions (i.e., cold weather, moderate precipitation). In Study 1, a two-way interaction between ECR and intention strength was observed, such that those with relatively stronger ECR demonstrated stronger intention–behavior relationships than those with relatively weaker ECR; this effect was invariant across experimental conditions. In Study 2, a significant 3-way interaction was observed, such that those with lower ECRs showed greater intention–behavior correspondence in the experimental group compared to the control. Together these findings suggest that the beneficial effects of implementation intentions on intention–behavior correspondence for physical activity may be more potent under challenging environmental conditions, and that they may be of special benefit for those with initially low ECRs.  相似文献

Whether human evaluative conditioning can occur without contingency awareness has been the subject of an intense and ongoing debate for decades, troubled by a wide array of methodological difficulties. Following recent methodological innovations, the available evidence currently points to the conclusion that evaluative conditioning effects do not occur without contingency awareness. In a simulation, we demonstrate, however, that these innovations are strongly biased toward the conclusion that evaluative conditioning requires contingency awareness, confounding the measurement of contingency memory with conditioned attitudes. We adopt a process-dissociation procedure to separate the memory and attitude components. In 4 studies, the attitude parameter is validated using existing attitudes and applied to probe for contingency-unaware evaluative conditioning. A fifth experiment incorporates a time-delay manipulation confirming the dissociability of the attitude and memory components. The results indicate that evaluative conditioning can produce attitudes without conscious awareness of the contingencies. Implications for theories of evaluative conditioning and associative learning are discussed.  相似文献

The Katz-Francis Scale of Attitude toward Judaism was developed to extend to the Jewish community a growing body of international research concerned to map the correlates, antecedents, and consequences of individual differences in attitude toward religion as assessed by the Francis Scale of Attitude toward Christianity. The internal consistency reliability and construct validity of the Katz-Francis Scale of Attitude toward Judaism were supported by data provided by 284 Hebrew-speaking female undergraduate students attending Bar-Ilan University. This instrument is commended for application in further research.  相似文献

The present study examined the transfer of higher-order cognitive strategy training to inhibitory control. Middle school students enrolled in a comprehension- and reasoning-focused cognitive strategy training program and passive controls participated. The training program taught students a set of steps for inferring essential gist or themes from materials. Both before and after training or a comparable duration in the case of the passive controls, participants completed a semantically cued Go/No-Go task that was designed to assess the effects of depth of semantic processing on response inhibition and components of event-related potentials (ERP) related to response inhibition. Depth of semantic processing was manipulated by varying the level of semantic categorization required for response selection and inhibition. The SMART-trained group showed inhibitory control gains and changes in fronto-central P3 ERP amplitudes on inhibition trials; whereas, the control group did not. The results provide evidence of the transfer of higher-order cognitive strategy training to inhibitory control and modulation of ERPs associated with semantically cued inhibitory control. The findings are discussed in terms of implications for cognitive strategy training, models of cognitive abilities, and education.  相似文献

This study examines two conflicting hypotheses regarding the association between traditional religiosity and new age belief: the “worldview hypothesis” suggesting a positive association between these two sets of beliefs; and the “functional alternative hypothesis” suggesting a negative association between these two sets of beliefs. A sample of 1209 undergraduate students attending the University of Maribor, Slovenia, completed the Francis Scale of Attitude towards Christianity as a measure of traditional religiosity and the Lavri? Scale of New Age Belief, alongside a measure of frequency of church attendance. The data demonstrated a positive correlation between attitude towards Christianity and new age belief, even after taking into account different levels of church attendance. These findings support the worldview hypotheses in favour of the functional alternative hypothesis.  相似文献

This study was designed to examine the effects of playing the online game World of Warcraft (WoW) on adolescents' social competence and loneliness, and to investigate the underlying mechanisms of the Internet‐affected social compensation hypothesis. The hypothesis states that being online affects adolescents' social competence as a result of a variety of communication partners and identity experiments online. A survey was conducted among 790 high school students. There appeared to be no direct effect between playing WoW and adolescents' social competence and loneliness. We did find an indirect effect via variety of communication partners. Adolescents who play WoW vary more in their communication partners, leading to an increase of social competence and a decrease of loneliness.  相似文献
