The responses toward denatonium saccharide and quinine by three rodent species differ from those exhibited by humans. This study measured the relative aversiveness of these two compounds in grasshopper mice (Onychomys leucogaster) to determine if this species responded similarly to or differently from these other rodents. In a choice test, the mice clearly preferred quinine over denatonium saccharide at concentrations of 1/10,000 and 1/50,000, but only marginally preferred quinine at a concentration of 1/1000. When denatonium or quinine was paired with toxicosis, both suppressed drinking at concentrations from 1/10,000 to 1/50,000, but only denatonium suppressed drinking at 1/100,000. Neither compound suppressed drinking at 1 part in million. Grasshopper mice perceived denatonium saccharide as more aversive than quinine in both experiments. Such a response resembled the behavior of humans more than that of the other three rodents previously tested. 相似文献

A study of 210 fourth, sixth, eighth, and tenth graders and adults was conducted to determine developmental trends in both destereotyping of traditionally gender-typed activities and preferences for those activities, and to compare activity preferences of tomboys with other females and with males at different ages. Tenth graders destereotyped less than the other age levels. Additionally, female subjects destereotyped traditionally boys' activities more than girls' activities and more than male subjects. Although nontomboys and boys showed a preference for gender-traditional activities, tomboys preferred traditional girls' and boys' activities equally. Self-defined tomboys do not reject traditionally female activities; instead, they expand their repertoire of activities to include both gender-traditional and nontraditional activities. It is suggested that girls who are able to transcend gender-role behavior in childhood may be the ones who will grow into androgynous adult women. 相似文献

This series of studies examined U.S. individuals' use of specific emotion regulation/coping strategies during the early months of the COVID-19 pandemic, investigated the factor structure among strategies during this universally experienced stressor, and the extent to which these factors predicted engagement in COVID-related health-promoting behaviors. In Study 1, participants (N = 520) rated their use of 17 strategies for coping with pandemic-related stress during the past 24 h. Differences emerged in strategy use across demographic groups (age, race, income). Results of exploratory factor analysis suggest a factor structure grouping strategies in terms of goals beyond emotion regulation per se, rather than phases of the emotion process or a binary adaptive versus maladaptive distinction. In Study 2 (N = 264), participants reported daily on their coping strategy use and weekly on their engagement in COVID-specific health behaviors for 22 days. Results of confirmatory factor analysis replicate the factor structure found in Study 1. Some significant associations of coping strategy use with health-promoting behaviors were observed, but these were sporadic and largely involved baseline measures rather than predicting change over time. Theoretical and practical implications are discussed. 相似文献

A 50-state statutory search revealed that variations exist in marital rape exemptions throughout the United States. States handle the question of marital rape in one of three ways: (1) by abolishing the exemption for husbands; (2) by qualifying the exemption; or (3) by allowing the exemption. Although marital rape is a topic that has been largely ignored by social psychology, it is an area ripe for psycho-legal analysis. Possible relationships between social psychology, marital rape exemptions, and privacy are discussed against a background of a psychological jurisprudence. 相似文献

Two experiments examined the generalizability of the effects of word length and phonological similarity with visual and auditory presentation in immediate verbal serial ordered recall. In Experiment 1, data were collected from 251 adult volunteers drawn from a broad cross-section of the normal population. Word length and phonological similarity in both presentation modes significantly influenced the group means. However, 43% of the subjects failed to show at least one of the effects, and the likelihood that effects appeared was highly correlated with verbal memory span. In Experiment 2, 40 subjects of the original sample were retested, 20 of whom had failed to show one or more effects in Experiment 1. Whether or not an effect had appeared for individual subjects on the first test session was a poor predictor of whether the effect would appear on retest. Finally, an analysis of subject reports demonstrated that the patterns of experimental data could be accounted for in part by the strategies that subjects reported using, and the effect of strategy was independent of the effect of span. The implications of these findings for theories of verbal short-term memory are discussed. 相似文献

This paper explores whether free recall performance and organization can be facilitated using computer-controlled interactive presentation, where stimulus presentation on Trial N+1 depends on the individual subject’s prior recall history. A series of experiments investigated the effects of two types of response-contingent presentation order manipulations and of selective tagging manipulation designed to highlight the presentation of previously nonrecalled items. An initial experiment using 20-word lists showed no differences among groups, due to a ceiling effect. Two subsequent experiments, using longer lists (30 and 40 words), found that recall and subjective organization were increased by selective tagging and by presentation orders that preserved the subject’s prior order of recall. The results demonstrate that subjects’ previous recall histories contain information that can be used to facilitate recall. The potential of other interactive manipulations is discussed. 相似文献

Priming with aggressive concepts increases males' attraction to media violence. It was hypothesized that priming with schema-irrelevant concepts would decrease interest relative to the effects of schema-relevant concepts, whether or not the schema-relevant concepts were also schema-consistent. Thirty male undergraduates used lists including aggressive (schema-consistent and schema-relevant), positive or prosocial (schema-inconsistent yet relevant), or entirely neutral (schema-irrelevant) words to write short stories (priming task), then received an opportunity to select videotaped film clips for viewing. Subjects primed by aggressive word lists included more aggression, anger, fear, and violence in their stories than did those in the aggression-inconsistent and aggression-irrelevant conditions, whereas aggression-inconsistent priming yielded more fun, helping, and joy than did other conditions. Aggressively primed subjects expressed more interest in films containing violence and hostility than did neutrally primed subjects, whereas aggression-inconsistent priming did not differ significantly from either aggressive (schema-consistent) or neutral (schema-irrelevant) priming. Findings indicate that the aggressive priming activates aggressive concepts that make violence and hostility more salient to individuals. Because male undergraduates typically express interest in violence, enhanced salience leads to increased interest. © 1992 Wiley-Liss, Inc. 相似文献

This study examines the relationship between psychosocial and study skill factors (PSFs) and college outcomes by meta-analyzing 109 studies. On the basis of educational persistence and motivational theory models, the PSFs were categorized into 9 broad constructs: achievement motivation, academic goals, institutional commitment, perceived social support, social involvement, academic self-efficacy, general self-concept, academic-related skills, and contextual influences. Two college outcomes were targeted: performance (cumulative grade point average; GPA) and persistence (retention). Meta-analyses indicate moderate relationships between retention and academic goals, academic self-efficacy, and academic-related skills (ps =.340,.359, and.366, respectively). The best predictors for GPA were academic self-efficacy and achievement motivation (ps =.496 and.303, respectively). Supplementary regression analyses confirmed the incremental contributions of the PSF over and above those of socioeconomic status, standardized achievement, and high school GPA in predicting college outcomes. 相似文献
