Four experiments are reported, investigating the mechanisms underlying the compatibility effect in the Implicit Association Test (IAT; Greenwald, McGhee, & Schwartz, 1998). All experiments involved two IATs: flower IAT, in which the target categories were flowers and insects, and number IAT, involving even and odd numbers as target categories. In Experiment 1, using the standard IAT procedure, the two IATs produced equal IAT effects, despite large differences in rated valence contrast between flowers and insects and between even and odd numbers. Experiment 2 used a procedure developed by Klauer and Mierke (2005) and produced results consistent with the view that valence plays a role in the flower IAT but not in the number IAT. Experiments 3 and 4 used manipulations similar to those developed by Rothermund and Wentura (2004) and showed that these manipulations affected the flower IAT and number IAT differently. The results provide converging evidence that the two types of IAT effects-one based on valence and one based on familiarity-are empirically dissociable.Experiments 1and 2 reported in this paper were conducted as an honours project by Marie Peek-O'Leary under the supervision of Sachiko Kinoshita. Parts of this paper were presented at the 44th Annual Meeting of the Psychonomic Society held in Vancouver, Canada, in November, 2003. 相似文献

In immediate serial recall, high-frequency words are better recalled than low-frequency words. A prevalent interpretation of this effect suggests that, at the point of recall, degraded representations undergo a reconstruction process calling upon long-term knowledge of the to-be-remembered items. Recently, Stuart and Hulme (2000) following Deese (1960), suggested that high-frequency items are better recalled due to their better long-term associative links. Their results revealed that a familiarisation procedure involving repeated presentations of the to-be-remembered items in pairs abolished the usual frequency effect. In the experiment reported here, an alternative interpretation of this result is examined. Prior to the memory task, subjects received either no familiarisation, item familiarisation, or pair familiarisation. Both item and pair familiarisation improved the item recall of low-frequency items to the same extent, suggesting that increased familiarity can account for the co-occurrence effect. 相似文献

Social anxiety disorder, whose onset peaks in adolescence, is associated with significant impairment. Despite the availability
of effective treatments, few affected youth receive services. Transporting interventions into schools may circumvent barriers
to treatment. The efficacy of a school-based intervention for social anxiety disorder was examined in a randomized wait-list
control trial of 35 adolescents (26 females). Independent evaluators, blind to treatment condition, evaluated participants
at preintervention, postintervention, and 9 months later. Adolescents in the intervention group demonstrated significantly
greater reductions than controls in social anxiety and avoidance, as well as significantly improved overall functioning. In
addition, 67% of treated subjects, compared to 6% of wait-list participants, no longer met criteria for social phobia following
treatment. Findings support the possible efficacy of school-based intervention for facilitating access to treatment for socially
anxious adolescents. 相似文献

Effects of modeling and contingent praise on infant imitation of three different responses was analyzed. Generalization to nonreinforced probe models was assessed both within and across response types. Three 12- to 14-month-old infants and their mothers participated in this study. During baseline the mothers provided models only. During treatment mothers modeled and also praised contingent upon infant matching of the training models. During interspersed probe trials the mothers modeled different responses, which, if matched by the infant, produced no praise. The three responses modeled were motor-with-toy, motor-without-toy, and vocal responses. The dependent measure was the percentage of maternal models that were matched by the infant within 6 s. Nonmatching responses of the same response type were also measured. Results showed a systematic increase in the percentages of training and probe models matched by the three infants following the introduction of the model-and-praise treatment condition. Nonmatching responses did not systematically increase. Thus, imitation generalized within response class, but not across response classes. 相似文献

Employees often evaluate leadership potential when selecting applicants for jobs that require leadership ability (e.g., supervisors, firefighter captains). Research has shown that influencing others is an important part of being an effective leader, yet employers rarely explicitly consider applicants' use of influence tactics when evaluating applicants' leadership potential. The purpose of this study was to explore applicant use of influence tactics in an employment interview and to determine how such use relates to interview ratings. The authors observed firefighter applicants' behavior during a selection role-play interview and recorded their use of influence tactics. Results indicated that firefighter applicants used soft tactics (e.g., ingratiation, rational persuasion) significantly more frequently than they used hard tactics (e.g., pressure, coalition). Soft tactic use was positively correlated with interview ratings. 相似文献

Although personality tests are widely used to select applicants for a variety of jobs, there is concern that such measures are fakable. One procedure used to minimize faking has been to disguise the true intent of personality tests by randomizing items such that items measuring similar constructs are dispersed throughout the test. In this study, we examined if item placement does influence the fakability and psychometric properties of a personality measure. Study participants responded to 1 of 2 formats (random vs. grouped items) of a personality test honestly and also under instructions to fake or to behave like an applicant. Results indicate that the grouped item placement format was more fakable for the Neuroticism and Conscientiousness scales. The test with items randomly placed fit the data better within the honest and applicant conditions. These findings demonstrate that the issue of item placement should be seriously considered before administering personality measures because different item presentations may affect the incidence of faking and the psychometric properties of the measure. 相似文献

Attentional control in the aging brain: insights from an fMRI study of the stroop task 总被引:18,自引:0,他引:18

Several recent studies of aging and cognition have attributed decreases in the efficiency of working memory processes to possible declines in attentional control, the mechanism(s) by which the brain attempts to limit its processing to that of task-relevant information. Here we used fMRI measures of neural activity during performance of the color-word Stroop task to compare the neural substrates of attentional control in younger (ages: 21-27 years old) and older participants (ages: 60-75 years old) during conditions of both increased competition (incongruent and congruent neutral) and increased conflict (incongruent and congruent neutral). We found evidence of age-related decreases in the responsiveness of structures thought to support attentional control (e.g., dorsolateral prefrontal and parietal cortices), suggesting possible impairments in the implementation of attentional control in older participants. Consistent with this notion, older participants exhibited more extensive activation of ventral visual processing regions (i.e., temporal cortex) and anterior inferior prefrontal cortices, reflecting a decreased ability to inhibit the processing of task-irrelevant information. Also, the anterior cingulate cortex, a region involved in evaluatory processes at the level of response (e.g., detecting potential for error), showed age-related increases in its sensitivity to the presence of competing color information. These findings are discussed in terms of newly emerging models of attentional control in the human brain. 相似文献

The capacity to incorporate significant words into the existing vocabulary and to use these words to form sentences with more mature syntactic structures emerges over a considerable time course in young deaf children who have undergone a cochlear implantation. The purpose of this follow-up study is to document the nature and time span of language production--in morphosyntactic and lexical skills--when a child's first experience with language sounds is provided artificially through electrical stimulation. To examine the development of these two aspects of linguistic processing, five deaf French children, all enrolled in similar postimplantation educational settings, were individually assessed at 6-month intervals over a period of 18 months. Computerized analyses were derived from their spontaneous speech in a 20-min standardized play session. Results for mean length of utterance and vocabulary revealed gradually improving performance for most children, in spite of the generally low starting point. Both measures of production nevertheless remained well below the norms established for normally hearing children. Although the achievement of higher production scores, which underlies more effective interpersonal exchanges, is evident after only 1 year of device use, it is clear that improvement does not always occur at the same pace, as shown by two of the children. This emphasizes the importance of longitudinal studies in documenting intersubject variability and intrasubject stability throughout the experience with an implant. 相似文献
