Four experiments examined the effects of encoding time on object identification priming and recognition memory. After viewing objects in a priming phase, participants identified objects in a rapid stream of non-object distracters; display times were gradually increased until the objects could be identified (Experiments 1-3). Participants also made old/new recognition judgments about previously viewed objects (Experiment 4). Reliable priming for object identification occurred with 150 ms of encoding and reached a maximum after about 300 ms of encoding time. In contrast, reliable recognition judgments occurred with 75 ms of encoding and continued to improve for encoding times of up to 1200 ms. These results suggest that recognition memory may be based on multiple levels of object representation, from rapidly activated representations of low-level features to semantic knowledge associated with the object. In contrast, priming in this object identification task may be tied specifically to the activation of representations of object shape. 相似文献

Every year, billions of dollars are spent gambling on the outcomes of the NCAA men's basketball tournament. This study examines how individuals make predictions for tournament pools, one of the most popular forms of betting, in which individuals must correctly predict as many games in the tournament as possible. We demonstrate that individuals predict more upsets (i.e., wins by a higher seeded team) than would be considered rational by a normative choice model, and that individuals are no better than chance at doing so. These predictions fit a pattern of probability matching, in which individuals predict upsets at a rate equal to past frequency. This pattern emerges because individuals believe the outcomes of the games are nonrandom and, therefore, predictable. 相似文献

The authors investigated the level of career maturity of nonadjudicated high school students without disabilities and 3 groups of adjudicated high school students: those without disabilities, those with learning disabilities, and those with emotional disturbance. Also investigated was the relationship between career maturity and behavioral functioning, using the Behavior Assessment System for Children‐Self‐Report of Personality (BASC‐SRP; C. R. Reynolds & R. W. Kamphaus, 1992). No significant differences existed between nonadjudicated and adjudicated students without disabilities. Adjudicated students with emotional disabilities and learning disabilities scored significantly lower than nonadjudicated high school students without disabilities on the overall measure of career maturity. Career maturity was found to be significantly but only moderately related to 8 behavioral domains on the BASC‐SRP. 相似文献

This paper reviews empirical studies on whether participating in mutual help groups for people with mental health problems leads to improved psychological and social functioning. To be included, studies had to satisfy four sets of criteria, covering: (1) characteristics of the group, (2) target problems, (3) outcome measures, and (4) research design. The 12 studies meeting these criteria provide limited but promising evidence that mutual help groups benefit people with three types of problems: chronic mental illness, depression/anxiety, and bereavement. Seven studies reported positive changes for those attending support groups. The strongest findings come from two randomized trials showing that the outcomes of mutual help groups were equivalent to those of substantially more costly professional interventions. Five of the 12 studies found no differences in mental health outcomes between mutual help group members and non-members; no studies showed evidence of negative effects. There was no indication that mutual help groups were differentially effective for certain types of problems. The studies varied in terms of design quality and reporting of results. More high-quality outcome research is needed to evaluate the effectiveness of mutual help groups across the spectrum of mental health problems. 相似文献

People are often taught using a combination of instruction and practice. In prior research, we have distinguished between model-based knowledge (i.e., acquired from explicit instruction) and experience-based knowledge (i.e., acquired from practice), and have argued that the issue of how these types of knowledge (and associated learning processes) interact has been largely neglected. Two experiments explore this issue using a dynamic control task. Results demonstrate the utility of providing model-based knowledge before practice with the task, but more importantly, suggest how this information improves learning. Results also show that learning in this manner can lead to "costs" such as slowed retrieval, and that this knowledge may not always transfer to new task situations as well as experientially acquired knowledge. Our findings also question the assumption that participants always acquire a highly specific "lookup" table representation while learning this task. We provide an alternate view and discuss the implications for theories of learning. 相似文献

The authors explore priming effects of pitch repetition in music in 3 experiments. Musically untrained participants heard a short melody and sang the last pitch of the melody as quickly as possible. Each experiment manipulated (a) whether or not the tone to be sung (target) was heard earlier in the melody (primed) and (b) the prime-target distance (measured in events). Experiment 1 used variable-length melodies, whereas Experiments 2 and 3 used fixed-length melodies. Experiment 3 changed the timbre of the target tone. In all experiments, fast-responding participants produced repeated tones faster than nonrepeated tones, and this repetition benefit decreased as prime-target distances increased. All participants produced expected tonic endings faster than less expected nontonic endings. Repetition and tonal priming effects are compared with harmonic priming effects in music and with repetition priming effects in language. 相似文献

The purpose of this study was to examine the association between peer facilitator adherence to motivational interviewing (MI) microskills and college student drinking behavior. First year students (N=67) took part in a Brief Alcohol Screening and Intervention for College Students (BASICS) led by peer facilitators trained in MI and BASICS. Participants were assessed pre- and 2 weeks post-intervention on contemplation to change, as well as, pre- and 3 months post- intervention on drinking quantity. Independent coders used the Motivational Interviewing Treatment Integrity scale (MITI, Moyers, Martin, Manuel, & Miller, 2003) to evaluate therapist MI adherence. Peer facilitators met beginning proficiency in MI on scores of empathy, the ratio of MI adherent behaviors to non-adherent behaviors and the ratio of open questions to total questions as defined by the MITI. Results indicated that a higher number of closed questions was related to less contemplation and a higher number of open questions was related to more contemplation post intervention. A higher number of simple reflections was associated with increased drinking at the 3 month assessment, however, complex reflections were found to attenuate the effect of simple reflections on changes in drinking. These findings highlight the importance of competent reflective listening skills and the need for continual training and supervision for peer facilitators. 相似文献

A culture promoting a strong desire for romantic relationships can greatly influence feelings of romantic loneliness and of closeness. In this study, the authors hypothesized that when not in a romantic relationship, U.S. young adults experience greater degrees of romantic loneliness because of a high desire for romantic relationships, compared with Korean young adults. The authors also predicted that when in a romantic relationship, U.S. young adults experience greater closeness to their romantic partner than do Korean young adults. Results revealed that in a sample of 227 U.S. and Korean students, U.S. students reported significantly higher levels of romantic loneliness than did Koreans when not in a romantic relationship and significantly lower levels of romantic loneliness when in a stable romantic relationship. U.S. students also reported a greater degree of closeness in romantic relationships than did Korean students. The results suggest that Western cultures' strong emphasis on the importance of romantic relationships may unduly amplify individuals' levels of loneliness. 相似文献

Cross-cultural examinations of the validity and reliability of the Beck Depression Inventory-II (Beck, Steer, Ball, & Ranieri, 1996) is essential for its use in assessment and monitoring of the effectiveness of suicide interventions across racial groups. We tested the fit of a second-order, two-factor model and the internal reliability of the BDI-II in a sample of 133 African Americans with a recent history of suicide attempts. Additionally, we examined the convergent validity with the Hamilton Rating Scale for Depression (Reynolds & Koback, 1995). The results indicate that the BDI-II is a reliable and valid measure of depressive symptoms for African American suicide attempters. 相似文献

Repeated training on a perceptual task can result in performance deterioration. In the case of vision, this practice-dependent decrease, or perceptual deterioration is restored by changing the target orientation, spatial location, or by taking a daytime nap. Behavioral studies suggest the locus of these performance changes to be primary visual cortex. We used fMRI to directly probe whether perceptual deterioration and nap-dependent maintenance of performance can be detected at the level of primary visual cortex. We also asked whether these changes are due to a bottom-up, stimulus-driven response or a top-down plasticity of attentional mechanisms. Subjects were scanned while performing a texture-discrimination task. Half the subjects took a nap between sessions. We measured the relationship between changes in performance and changes in BOLD signal modulation between the two groups. Non-nappers showed performance deterioration that was significantly correlated with decreased BOLD signal modulation, exclusively in area V1 and limited to the bottom-up condition. In contrast, no change was detected in performance and BOLD response in the two conditions for nappers. These results indicate that napping prevented performance deterioration, which was reflected in the fMRI response of neurons in V1. Without a nap, perceptual deterioration was related to decreases in the stimulus-driven, bottom-up representation, rather than decreases in attentional modulation to the stimulus. 相似文献
