Explicitly cued task switching slows performance relative to performing the same task on consecutive trials. This effect appears to be due partly to more efficient encoding of the task cue when the same cue is used on consecutive trials and partly to an additional task-switching process. These components were examined by comparing explicitly cued and voluntary task switching groups, with external cues presented to both groups. Cue-switch effects varied in predictable ways to dissociate explicitly cued and voluntary task switching, whereas task-switch effects had similar characteristics for both instructional groups. The data were well fitted by a mathematical model of task switching that included a cue-encoding mechanism (whereby cue repetition improves performance) and an additional process that was invoked on task-switch trials. Analyses of response-time distributions suggest that this additional process involves task-set reconfiguration that may or may not be engaged before the target stimulus is presented. 相似文献

Switching auditory attention incurs a performance decrement (i.e. auditory attention-switch costs). Using an auditory attention-switching paradigm, we aimed to generalise these across different response mappings. In all three experiments, two number words, spoken by a female and male speaker, were presented dichotically via headphones. A visual cue indicated the gender of the to-be-attended speaker in each trial. The task was a magnitude judgement of the relevant number word (i.e. smaller vs. larger than 5). We additionally varied the interval between cue onset and auditory stimulus onset (cue-stimulus interval) to explore cue-based preparatory effects. In Experiment 1, attention switching was more costly with direct-verbal responses (e.g. ‘smaller’) than in the shadowing task (e.g. ‘three’). In Experiment 2, performance was largely similar for direct-verbal responses and abstract-verbal responses (e.g. ‘left’). In Experiment 3, performance was generally worse with abstract-verbal responses than with abstract-manual responses (e.g. left key press) and auditory attention-switch costs were similar for both response mappings. Overall, auditory switch costs occurred more or less invariably across response mappings in categorical (magnitude) judgements suggesting a minor role of the response mapping in auditory attention switching. Furthermore, verbal identity-based judgements (i.e. shadowing) generally seem to benefit from ideomotor compatibility. 相似文献

Rural economically deprived adolescent males, who had been previously surveyed as high school seniors concerning their post-high school plans, were surveyed again 1 yr later concerning their present occupational status and feelings of personal satisfaction. The Ss had been divided in an earlier study into two groups, low identification males (LIM) and high identification males (HIM) based upon independent evaluators' judgments of the adequacy of their fathers as identification models. Each group's responses to the survey were compared. The results indicate that there are no statistically significant differences between the two groups on the variables of satisfaction, having received counseling from others and optimism about the future. There are statistically significant differences between the current occupational status and future occupational plans of the two groups. 相似文献

The content of each of the Occupational and Nonoccupational scales on the Strong Vocational Interest Blank for Women (SVIB-W; Form TW398) was described in terms of the categories used for the Basic Interest scales. The number of common items scored on the Occupational or Nonoccupational scales and the Basic scales was cross-tabulated for each pair of scales. A variety of interest factors was represented on each of the Occupational and Nonoccupational scales. Several shortcomings of the SVIB-W (e.g., restricted range of interests represented in item pool, no Occupational scale for “outdoors” occupations, and questionable validity of Diversity scale) were noted. 相似文献

Previous reports from this laboratory have shown that untrained listeners cannot name the order of sounds in extended sequences of unrelated items such as hisses, tones, and buzzes at item durations of 200 msec, even though identification of order for the sounds of speech and music is accomplished readily at much shorter item durations. The present study indicates that under appropriate conditions subjects can be trained to distinguish between and to identify permuted orders within sequences of nonrelated sounds each lasting only 10 msec or less. Evidence is presented suggesting that much of what passes for direct identification of order is actually based on prior identification of a larger pattern. Two principal mechanisms seem to mediate discrimination of auditory temporal order: (1) fine resolution (requiring prior training) permitting identification of over-all patterns and capable of operating with item durations of only a few msec; (2) coarse resolution (special prior training not required) allowing naming of order of items having minimal durations usually above 200 msec for unfamiliar sequences. 相似文献

This essay explores the American Girl Just Like You doll through a variety of feminist lenses. It was inspired by my experiences chaperoning my friend Grace (aged eleven) to the American Girl Store in New York City, and returning to the store to shop for my own doll. I returned to the store because I was not sure why I was so extremely disturbed by this doll. The doll is not emaciated, not overtly sexy, and marketed along with outfits that supposedly send girls the message that they can achieve their goals. She comes in a variety of skin, eye, and hair colors, and the line is therefore marketed as racially and ethnically sensitive. I argue that although the Just Like You line appears to be empowering and racially sensitive on a superficial level, an in‐depth feminist analysis indicates that it is not. In fact, the Just Like You line is highly problematic from a feminist perspective. 相似文献

Scholarship in the multidisciplinary field of genocide studies often emphasizes body counts and the number of biological deaths as a way of measuring and comparing the severity and scope of individual genocides. The prevalence of this way of framing genocide is problematic insofar it risks marginalizing the voices and experiences of victims who may not succumb to biological death but nevertheless suffer the loss of family members and other loved ones, and suffer the destruction of relationships, as well as the foundational institutions that give rise to and sustain those relationships. The concept of social death, which Claudia Card offers as the central evil of genocide, marks a radical shift in conceptualizing genocide and provides space for recovering the marginalized voices of many who suffer the evils of genocide but do not suffer biological death. Here her concept of social death is explored, defended, and criticized. 相似文献
