Four hundred forty-eight children 3–12 years of age generated category exemplars for 33 distinct categories. The percentage
of the participants reporting each exemplar, the percentage of the participants reporting each exemplar first, the percentage
of the participants reporting each exemplar across age groups (3–5 years, 6–8 years, and 9–12 years), and the mean rank of
each exemplar are presented. A full version of the 29 category norms may be downloaded from www.psychonomic.org/archive. 相似文献

Several clinical trials have tested the hypothesis that smoking cessation treatments with a mood management component derived from cognitive behavior therapy (CBT) for depression would be specifically effective for depression-vulnerable smokers, with mixed results. This trial addressed methodological concerns with some of the previous studies to clarify whether depression vulnerability does in fact moderate CBT smoking cessation outcome. The study compared 8-session group CBT with a time-matched comparison group condition in a sample of 100 cigarette smokers randomized to treatment condition. Each treatment group was led by one of 7 American University clinical psychology graduate students; therapists were crossed with treatment conditions. Outcome (7-day point prevalence abstinence) was evaluated 1 month and 3 months after quit date. Baseline self-reported depression vulnerability (sample median split on the Depression Proneness Inventory) moderated treatment response, such that more depression-prone smokers fared better in CBT whereas less depression-prone smokers fared better in the comparison condition. These results may have implications for determining when to use CBT components in smoking cessation programs. 相似文献

[Hulse and Dorsky, 1977] and [Hulse and Dorsky, 1979] found that rats, like humans, learn sequences following a simple rule-based structure more quickly than those lacking a rule-based structure. Through two experiments, we explored whether two additional species—domesticated horses (Equus callabus) and chickens (Gallus domesticus)—would show this same propensity. In both experiments, subjects encountered either a structured or unstructured sequence of food quantities in a runway paradigm. In both experiments, subjects exposed to structured patterns of food quantities learned to track sequences of food quantities more efficiently than those exposed to patterns lacking such structure by running fast for large food quantities and slowly for small food quantities. These results provide evidence that horses and chickens track simple sequences similarly to humans and rats. 相似文献

This study explores the potential relationship of guns in students’ homes with attitudes indicative of tolerance of violence, negative attitudes toward women and their roles, and attitudes suggestive of myths regarding sexual assault. Seniors in Kentucky high schools whose families possessed guns (n = 1,749) produced higher scores on scales measuring these variables as well as on scales of relationship dependency and religious involvement than seniors whose families did not own guns (n = 912). Students whose families owned more than 10 guns tended to score highest on these measures compared with students whose families owned no guns or a few guns. Because of lower effect sizes, these significant associations require further investigation. 相似文献
