Paruresis, characterized by the difficulty or inability to urinate in a variety of social contexts, is a scientifically under-studied phenomenon. One reason for this state of affairs is the paucity of reliable and valid measures for assessing this problem. The present article attempted to address this limitation by investigating the psychometric properties and validity of a new measure of paruresis: the Shy Bladder Scale (SBS). In two undergraduate samples, the SBS demonstrated excellent internal consistency and a stable factor structure assessing difficulty urinating in public, impairment and distress, and paruresis-related fear of negative evaluation. Undergraduate students evidenced very low levels of paruresis-related concerns. In contrast, SBS scores were markedly elevated among individuals recruited from an online support network who appeared to meet diagnostic criteria for paruresis-specific social phobia. Our findings highlight the SBS's potential utility as a measure of paruresis in clinical and research contexts. 相似文献

Domain knowledge is a powerful predictor of success in many complex tasks, but do general cognitive abilities also play a role? To investigate this question, we had 155 participants representing a wide range of poker experience and skill complete tests of poker knowledge, working memory capacity (WMC), and two components of skill in Texas Hold’Em poker: the ability to remember hands and the ability to evaluate hands. Not surprisingly, poker knowledge positively predicted performance in all of the Hold’Em tasks. However, WMC added significantly to the prediction, and there was no evidence for interactions between poker knowledge and WMC. That is, WMC was as important as a predictor of performance at high levels of poker knowledge as at low levels, suggesting that domain knowledge may not always enable circumvention of WMC in domain-relevant tasks. 相似文献

In two experiments, we examined the development of sensitivity to the inductive potential of shared novel noun and feature labels. Children (4-year-olds, 5-year-olds, and 8-year-olds) and adults were presented with a complete base stimulus and an incomplete target. The task was to infer whether the missing target feature matched the corresponding base feature. The base and target were given matching or mismatching novel labels, which were either count nouns or adjectives describing object features. Use of matching labels for induction increased with age. Nevertheless, all age groups were more likely to make inferences based on novel noun labels rather than feature labels. These results support the view that even preschool children grasp the conceptual significance of count nouns for induction. 相似文献

Conventionally, memory and reasoning are seen as different types of cognitive activities driven by different processes. In two experiments, we challenged this view by examining the relationship between recognition memory and inductive reasoning involving multiple forms of similarity. A common study set (members of a conjunctive category) was followed by a test set containing old and new category members, as well as items that matched the study set on only one dimension. The study and test sets were presented under recognition or induction instructions. In Experiments 1 and 2, the inductive property being generalized was varied in order to direct attention to different dimensions of similarity. When there was no time pressure on decisions, patterns of positive responding were strongly affected by property type, indicating that different types of similarity were driving recognition and induction. By comparison, speeded judgments showed weaker property effects and could be explained by generalization based on overall similarity. An exemplar model, GEN-EX (GENeralization from EXamples), could account for both the induction and recognition data. These findings show that induction and recognition share core component processes, even when the tasks involve flexible forms of similarity. 相似文献

In this study we consider whether bullies and victims are disliked by most of their classmates, or whether antipathy is concentrated among the occupants of these roles. Antipathy nominations were collected from a community sample of 699 Finnish adolescents (14 to 17 years of age), who described their own bullying and victimization, as well as problem behaviors and school engagement. Victimization was associated with antipathy, but the strength of the association differed according to characteristics of the nominator. Victimization was related to antipathy when the nominator was high on bullying but not low. Similarly, bullying was related to antipathy when the nominator was high on victimization, but not low. The findings indicate that although bullies and victims have elevated mean levels of rejection, they are not disliked by most peers but rather by those who report themselves to be high on these attributes. 相似文献

Current models of inductive reasoning in children and adults assume a central role for categorical knowledge. A recent paper by Sloutsky and Fisher challenges this assumption, showing that children are more likely than adults to rely on perceptual similarity as a basis for induction, and introduces a more direct method for examining the representations activated during induction. This method has the potential to constrain models of induction in novel ways, although there are still important challenges. 相似文献

ABSTRACTStatistical learning refers to the extraction of probabilistic relationships between stimuli and is increasingly used as a method to understand learning processes. However, numerous cognitive processes are sensitive to the statistical relationships between stimuli and any one measure of learning may conflate these processes; to date little research has focused on differentiating these processes. To understand how multiple processes underlie statistical learning, here we compared, within the same study, operational measures of learning from different tasks that may be differentially sensitive to these processes. In Experiment 1, participants were visually exposed to temporal regularities embedded in a stream of shapes. Their task was to periodically detect whether a shape, whose contrast was staircased to a threshold level, was present or absent. Afterwards, they completed a search task, where statistically predictable shapes were found more quickly. We used the search task to label shape pairs as “learned” or “non-learned”, and then used these labels to analyse the detection task. We found a dissociation between learning on the search task and the detection task where only non-learned pairs showed learning effects in the detection task. This finding was replicated in further experiments with recognition memory (Experiment 2) and associative learning tasks (Experiment 3). Taken together, these findings are consistent with the view that statistical learning may comprise a family of processes that can produce dissociable effects on different aspects of behaviour. 相似文献

This investigation demonstrates that emotion regulation can be driven by considerations of utility per se. We show that as participants prepared for a negotiation, those who were motivated to confront (vs. collaborate with) another person believed that anger would be more useful to them. However, only participants who were motivated to confront another and expected to receive a monetary reward for their performance (i.e., high utility), were motivated to increase their anger in preparation for the negotiation. Participants who were motivated to confront another but did not expect their performance to be rewarded (i.e., low utility), did not try to increase their anger, even though they expected anger to be useful in the negotiation. Such patterns demonstrate that people are motivated to experience even unpleasant emotions to maximise utility. 相似文献

Data from a 25-year prospective study of 194 individuals indicated that teacher and peer reports of aggression, compliance, and self-control at age 8 distinguished high-agreeable from low-agreeable adults at age 33. Profile analyses revealed two behavioral types in childhood and two personality types in adulthood, with considerable continuity in the composition of these high- and low-agreeable types over time. High-agreeable childhood types had fewer disobedience and concentration problems than low-agreeable childhood types, and among boys, high-agreeable childhood types had better school grades and fewer behavior problems than their low-agreeable counterparts. High-agreeable adulthood types reported less alcoholism and depression, fewer arrests, and more career stability than did low-agreeable adulthood types. 相似文献
