Three experiments compared human performance on temporal generalization tasks with either one or two different, and distinct, standard durations encoded. In the first two experiments participants received presentations of two different standards at the beginning of each trial block and were instructed to encode either one or both of them. When instructed to encode one standard they then had to judge whether each of a number of comparison stimuli was or was not that standard. When instructed to encode both they were then tested using just one of the standards but the participants were unaware, at the time of encoding, which standard would later be used as a reference. No marked effect of the number of temporal standards encoded was found. In Experiment 3 participants received either one or two temporal standards and had to use both when two were presented. This manipulation produced flatter generalization gradients when two standards were encoded than when just one was, and modelling attributed this difference mainly to an increase in reference memory variability in the double-standard case. This suggests that the variability of representation of durations in temporal reference memory can be systematically increased by increasing temporal reference memory load. 相似文献

OBJECTIVE: The current study tested the effectiveness of interactive versus passive distraction that was delivered via a virtual reality type head-mounted display helmet for children experiencing cold pressor pain. DESIGN: Forty children, aged 5 to 13 years, underwent 1 or 2 baseline cold pressor trials followed by interactive distraction and passive distraction trials in counterbalanced order. MAIN OUTCOME MEASURES: Pain threshold and pain tolerance. RESULTS: Children who experienced either passive or interactive distraction demonstrated significant improvements in both pain tolerance and pain threshold relative to their baseline scores. In contrast, children who underwent a second cold pressor trial without distraction showed no significant improvements in pain tolerance or threshold. CONCLUSION: Although both distraction conditions were effective, the interactive distraction condition was significantly more effective. Implications for the treatment of children's distress during painful medical procedures are discussed. 相似文献

Background. Research on bullying increasingly focuses on social processes, showing that group membership affects children's responses to bullying scenarios. Additionally, correlational research has shown links between norms of cooperation and prosocial behaviour, and between competition and more aggressive forms of behaviour. Aims. This paper focuses on how children's peer group membership affects their group‐based emotions in response to an intergroup bullying incident, and the action tendencies that these emotions predict, in the context of different background norms (for competitive or cooperative behaviour). Sample. Italian schoolchildren, 10–13 years old (N= 128, 65 males) took part in this study. Methods. Participants were randomly assigned to the group of a perpetrator, target, or third‐party group member described in a scenario. Next, they played a game designed to induce a cooperative, competitive, or neutral norm, and read the scenario. They then answered a questionnaire measuring their group‐based emotions. Results. Results underscored the role of norms and group processes in responses to bullying. In particular, children exposed to a cooperative norm expressed less pride and more regret and anger about the bullying than those in other conditions. Conclusions. This study indicates that the influence peer groups have on bullying may be tempered by the introduction of a cooperative normative context to the school setting. 相似文献

We sought to advance understanding of the processes underlying the efficacy of exposure therapy and particularly the phenomenon of return of fear (ROF) following treatment by drawing on a social psychological view of phobias as attitudes. Specifically, a dual process theory of attitude-related behavior predicts that a positive response to exposure therapy may reflect change in either the automatic (the attitude representation itself) or controlled (skills and confidence at coping with the fear) responses to the phobic stimulus, or both. However, if the attitude representation remains negative following treatment, ROF should be more likely. We tested this hypothesis in a clinical sample of individuals with public speaking phobia using a single-session exposure therapy protocol previously shown to be efficacious but also associated with some ROF. Consistent with predictions, a post-treatment implicit measure of attitudes toward public speaking (the Personalized Implicit Association Test [PIAT]) predicted ROF at 1-month follow-up. These results suggest that change in the automatically activated attitude toward the phobic stimulus is an important goal of exposure therapy and that an implicit measure like the PIAT can provide a useful measure of such change by which to gauge the adequacy of exposure treatment and predict its long-term efficacy. 相似文献
