Recall of a portion of a previously experienced list benefits subsequent recall of that portion of the list but leads to poorer recall of nonpracticed items from the same set (Anderson, Bjork, & Bjork, 1994). One explanation for this retrieval-induced forgetting is that during practice of part of a set, the non-practiced items compete for recall and are suppressed; this suppression process inhibits later recall of the nonpracticed items. Two experiments were conducted to investigate the relationship between distinctive processing of the original set and retrieval-induced forgetting, on the assumption that distinctive processing reduces response competition. In the first experiment, distinctive processing induced by difference judgments among the studied items did reduce forgetting relative to a standard encoding task and a similarity judgment task. In fact, the difference judgment task completely eliminated retrieval-induced forgetting. In the second experiment, the similarity judgment task was analyzed in relation to a task assumed to foster associative integration (Anderson & McCulloch, 1999). Even though the similarity judgment met the requirements for associative integration, retrieval-induced forgetting persisted following similarity judgment. The results are consistent with the view that distinctive processing benefits memory within an organizational context (Hunt & McDaniel, 1993; Smith & Hunt, in press). 相似文献

Three experiments investigated the effects of attention on the detection of luminance targets in a spatial-cuing paradigm. Gabor patch stimuli of 30, 60, or 90 ms duration, equated for detectability, were presented (a) against a uniform field with a checkerboard backward mask, (b) atop a 15% luminance pedestal with a backward mask, or (c) atop a luminance pedestal with no backward mask. Signal detection analysis showed that detection sensitivity was significantly enhanced at attended locations for all observers when backward masks were used, both when targets were presented against a uniform field and when a pedestal was used. However, when no masks were used there was no cuing advantage of any kind. The results show that the cuing effect in simple detection depends on the use of backward masks, a finding that resolves the inconsistencies previously associated with studies of this type. 相似文献

Two experiments investigated the development of the word length effect in children aged 4 to 10 years, comparing auditory and visual stimuli. The question addressed was whether word length effects emerged earlier with auditory presentation or visual presentation, or whether they emerged at the same age regardless of presentation modality. Results provided evidence that word length effects emerge earlier with visual than auditory presentation. The implication of our results is that with visual presentation, 4-year-olds engage in some form of verbalization strategy that involves obtaining phonological representations of picture names and mapping them on to articulatory output plans. This strategy is clearly verbal in nature, but is not necessarily characterised as cumulative verbal rehearsal. 相似文献

Stress, self-esteem, and suicidal ideation in late adolescents 总被引:6,自引:0,他引:6
The relationships among stress, self-esteem, and suicidal ideation in late adolescents were examined in a group of college students. Multiple regression analysis indicated that both stress and self-esteem were significantly related to suicidal ideation; low self-esteem and stressful life events significantly predicted suicidal ideation. The hypothesis that self-esteem would moderate the effects of life stressors on suicidal ideation was supported at the .06 level. A significant minority of the sample indicated having thoughts severe enough to be classified as clinical suicidal ideation. In general, participants who had experienced negative life events in the 6 to 12 months prior to participating in the study had lower self-esteem than those who had similar stresses within the prior six months. However, the opposite was true for clinical suicidal ideators; those who experienced negative life stressors recently had lower self-esteem than those who experienced negative life events six months to a year in the past. 相似文献

Six experiments showed that being excluded or rejected caused decrements in self-regulation. In Experiment 1, participants who were led to anticipate a lonely future life were less able to make themselves consume a healthy but bad-tasting beverage. In Experiment 2, some participants were told that no one else in their group wanted to work with them, and these participants later ate more cookies than other participants. In Experiment 3, excluded participants quit sooner on a frustrating task. In Experiments 4-6, exclusion led to impairment of attention regulation as measured with a dichotic listening task. Experiments 5 and 6 further showed that decrements in self-regulation can be eliminated by offering a cash incentive or increasing self-awareness. Thus, rejected people are capable of self-regulation but are normally disinclined to make the effort. 相似文献

Pediatric psychologists use the tools of assessment to evaluate the psychological functioning of youth with chronic and acute medical illnesses. This study is an exploration of the use of a performance-based measure, the Hand Test (HT; Wagner, 1983), with pediatric medical patients. A sample of medical inpatients (n = 27) and psychiatric outpatients (n = 24) were administered the HT, a self-report measure, and a parent-report behavior rating scale. Results indicate that the psychiatric group scored higher than the medical group on HT Aggression, Withdrawal, and Pathological scores. The Aggression (d = 0.90) and Pathological (d = 0.80) variables were particularly robust in differentiating between groups, but the Crippled variable did not differ between groups. Hierarchical logistic regression demonstrated the incremental validity of the HT over behavior ratings alone in the classification of clinical groups. Analyses indicated that the HT can add important information in the differentiation of medically ill children from those with psychological disturbance. 相似文献

Self-touching is defined as self-directed touches, e.g., scratching or rubbing, that have no apparent conscious motivation. Earlier research on self-touching focused on internal processes associated with self-touching, e.g., mental conflict, while more recent research has considered external motivators, such as an auditory or visual presentation of a provocative stimulus, e.g., leeches. Here, 110 undergraduate psychology students (68 women, 42 men; M age = 18.7 yr., SD = 1.0) were shown a video about chiggers to replicate previous findings, while simultaneously studying the social influence of self-touching modeled by the presenter. A significant interaction was found as modeled self-touching significantly increased participants' self-touching when they were also attending to the video about chiggers. The results are discussed in terms of potential processes underlying this behavior and directions for research. 相似文献

The vertical dimension of interpersonal relations (relating to dominance, power, and status) was examined in association with nonverbal behaviors that included facial behavior, gaze, interpersonal distance, body movement, touch, vocal behaviors, posed encoding skill, and others. Results were separately summarized for people's beliefs (perceptions) about the relation of verticality to nonverbal behavior and for actual relations between verticality and nonverbal behavior. Beliefs/perceptions were stronger and much more prevalent than were actual verticality effects. Perceived and actual relations were positively correlated across behaviors. Heterogeneity was great, suggesting that verticality is not a psychologically uniform construct in regard to nonverbal behavior. Finally, comparison of the verticality effects to those that have been documented for gender in relation to nonverbal behavior revealed only a limited degree of parallelism. 相似文献
