We investigated people's ability to decide how much time to spend on the task at hand. To make such decisions well, one must take into account, among other things, the cost of failing and how one's task performance changes as a function of time. We first investigated timing decisions when the underlying task was perceptual. Decisions were highly efficient and suggested that people can make good use of perceptual knowledge and abstract reward information. Previous studies have found that perceptual decisions are generally optimal, but that cognitive decisions are generally suboptimal--a perception-cognition gap. Does a similar gap exist for timing decisions? We compared timing decisions for a perceptual task with timing decisions for more cognitive tasks. Performance was highly similar across the tasks, which suggests that knowledge can be acquired, and used to make timing decisions, in an equally efficient way regardless of whether that knowledge is derived through perceptual or cognitive experience. 相似文献

Varying risk factors for both incarceration and mental health diagnoses have been identified for female juveniles, highlighting the need for gender-specific assessments and treatment protocols. The purpose of this study is to determine how the prevalence rates of mental health symptoms differ in male and female juvenile offenders. It was hypothesized that the prevalence rates would be greater for females than males. This study found significant differences between males and females on several clinical scales. These findings are consistent with past studies that have identified differences in mental health symptoms between genders. 相似文献

This study replicates and extends prior studies of the dimensionality, convergent, and external validity of African Self-Consciousness Scale scores with appropriate exploratory factor analysis methods and a large gender balanced sample (N = 348). Viable one- and two-factor solutions were cross-validated. Both first factors overlapped significantly and were labeled "Embracing African Heritage." The second subscale of the two-factor solution was labeled "Refusal to Deny African Heritage." Only the structural validity of the first factor of the two-factor solution was fully consistent with prior findings. Partial evidence of convergent validity was found for all factors, and only the second factor of the two-factor solution received external validity support. Implications for usage of the African Self-Consciousness Scale and recommendations for further investigation are discussed. 相似文献

Recent work suggests that text messaging impairs simulated and actual driving performance and that this impairment exceeds that of conversing on a cell phone while driving. Additionally, research has shown that text messaging is common in several countries, and despite drivers acknowledging the high risk involved in doing so, drivers continue to engage in this behaviour – regardless of legislation banning it. A nationwide online survey in New Zealand, of 1057 respondents, collected anonymous self-report data regarding the frequency of cell phone use (conversing and text messaging) while driving, beliefs concerning the safety of conversing or text messaging while driving. This article presents part of the results of that study – focusing on text messaging behaviour and risk perception regarding text messaging while driving. Over half of respondents surveyed reported sending or reading between 1 and 5 text messages while driving in a typical week. Despite this, 89% of participants agreed that text messaging while driving in general impairs driving performance. There were no gender differences between the number of text messages read and sent. Age was found to be an important indicator of participant’s willingness to engage in text messaging while driving, with younger drivers more likely to engage in this behaviour. The implications of these findings for future research and countermeasure development are discussed. 相似文献

Why do people behave aggressively toward romantic partners, and what can put the brakes on this aggression? Provocation robustly predicts aggression in both intimate and nonintimate relationships. Four methodologically diverse studies tested the hypothesis that provocation severity and relationship commitment interact to predict aggression toward one's romantic partner, with the aggression-promoting effects of provocation diminishing as relationship commitment increases. Across all four studies, commitment to one's romantic relationship inhibited aggression toward one's partner when individuals were severely (but not mildly) provoked. Study 4 tested the hypothesis that this Partner Provocation × Commitment interaction effect would be strong among individuals high in dispositional tendencies toward retaliation but weak (perhaps even nonexistent) among individuals low in such tendencies. Discussion emphasizes the importance of understanding instigating, impelling, and inhibiting processes in the perpetration of aggression toward intimate partners. 相似文献

Eight studies (N=2,973) tested the theory that gratitude is related to fewer depressive symptoms through positive reframing and positive emotion. Study 1 found a direct path between gratitude and depressive symptoms. Studies 2-5 demonstrated that positive reframing mediated the relationship between gratitude and depressive symptoms. Studies 6-7 showed that positive emotion mediated the relationship between gratitude and depressive symptoms. Study 8 found that positive reframing and positive emotion simultaneously mediated the relationship between gratitude and depressive symptoms. In sum, these eight studies demonstrate that gratitude is related to fewer depressive symptoms, with positive reframing and positive emotion serving as mechanisms that account for this relationship. 相似文献

Systematic monitoring of individual therapy progress, coupled with feedback to the therapist, reliably enhances therapy outcome by alerting therapists to individual clients who are off track to benefit by the end of therapy. The current paper reviews the possibility of using similar systematic monitoring and feedback of therapy progress as a means to enhance couple therapy outcome, including what measures of therapy progress are most likely to be useful, how to structure feedback to be most useful to therapists, and the likely mediators of the effects of therapy progress feedback. One implicit assumption of therapy progress feedback is that clients unlikely to benefit from therapy can be detected early enough in the course of therapy for corrective action to be taken. As a test of this assumption, midtherapy progress was examined as a predictor of final couple therapy outcome in a sample of 134 distressed couples. Either a brief 7- or 32-item assessment of couple therapy progress at midtherapy detected a substantial proportion (46%) of couples who failed to benefit by the end of therapy. Given that failure to benefit from couple therapy is somewhat predictable across the course of therapy, future research should test whether systematic monitoring and feedback of progress could enhance therapy outcome. 相似文献

Mainstream North American media promotes the message that attaining a thin, youthful appearance is central to a woman’s value and social role while appearing older is highly undesirable. However, appearance ideals and attitudes toward aging differ substantially across cultural and ethnic groups, which may influence the degree to which one internalizes media ideals and holds anti-aging attitudes. Consequently, this study examined the relationships between internalization of the youthful, thin-ideal appearance perpetuated by mainstream North American media and attitudes toward the elderly in a sample of 281 undergraduate females under the age of 30 attending a university in the Western United States. Specifically, European American (n?=?115), Asian American/Pacific Islander (n?=?74), Hispanic/Latina (n?=?52), and African American (n?=?42) women voluntarily completed self-report measures of internalization of media ideals and attitudes towards older adults. Attitudes towards the elderly were significantly more negative at higher levels of internalization of North American appearance ideals, independent of ethnicity. These data suggest that internalization of North American appearance ideals perpetuated by media are related to negative attitudes towards older adults. Future research should investigate the influence of negative attitudes about aging on behaviors toward older adults or one’s own aging process. 相似文献

Inhibitory control is widely hypothesized to be the cornerstone of executive function in childhood and the central deficit in a number of developmental disorders, including attention‐deficit/hyperactivity disorder (ADHD). However, recent evidence from adults indicates that performance on response inhibition tasks may primarily reflect non‐inhibitory attentional control (context monitoring) processes. Yet it may be that inhibition plays a more central role in childhood – a time when the architecture of cognitive processes might be more transparent due to wide variability in skill level. Here we directly test inhibitory and context monitoring explanations of task performance on a Go/No‐Go task in a large group of children 4–12 years of age. We conclude that traditional inhibitory conceptualizations of task performance on the Go/No‐Go task cannot account for our findings, calling into question evidence supporting a central role for inhibitory control in cognitive development or developmental psychopathology. 相似文献
