Stimulus-independent thoughts (SITs) are streams of thoughts and images unrelated to immediate sensory input. Four experiments examined the contribution of aspects of working memory to production of SITs. In Experiments 1 and 2, interventions that were targeted on, respectively, phonological and visuospatial components of working memory both interfered with production of SITs, but there was evidence that these tasks also made demands on central executive resources. Experiments 3 and 4 specifically examined the hypothesis that production of SITs and control of nonproceduralized tasks both depend on central executive resources, and so should show mutual interference. In Experiment 3, prior practice on pursuit rotor and memory tasks reduced the interference with SITs from concurrent task performance. In Experiment 4, randomness within a task involving random-number generation was less when SITs were being produced concurrently than it was when they were not. The results suggest that production of SITs depends on central executive resources. 相似文献

The study investigated the differential ability of similarity theory and social exchange theory to predict the effects of self-disclosure in a counseling versus a friendship encounter The participants were 80 undergraduates. A 2 (counseling or friendship) × 2 (positive or negative disclosure) × 2 (relevant or irrelevant disclosure) design was used in which participants rated the videotaped self-disclosure of an individual in an initial dyadic encounter. Unequivocal support was not obtained for either of the theories, but relationship context (counselor vs. peer) influenced the effects of disclosure as measured on counselor-peer and relationship characteristics. A unique feature of the study was the use of the Client Reactions System (CRS) to measure participants' immediate reactions to self-disclosure. The CRS demonstrated both relationship context and valence of disclosure (positive or negative) effects. 相似文献

Abstract— Previous research has shown that split-brain (callosotomy) patients search through visual displays twice as fast as normal observers when items are divided evenly between visual hemifields, as though each disconnected hemisphere possessed its own attentional scanning system (Luck, Hillyard, Mangun, & Gazzaniga, 1989, 1994) Results from 3 split-brain patients in the present study indicate that the ability to limit search to a relevant subset of the visual display is lateralized to the left cerebral hemisphere. This ability to perform guided search was not shown in the right hemisphere, even when the search time in that hemisphere was superior to search time in the left Furthermore, guided search was observed for both hemifields in normal control observers. These findings suggest that, as with higher cognitive processes such as language, strategic visuospatial attentional processes are preferentially lateralized to the left cerebral hemisphere. The findings also imply that the callosum mediates guided search in the right hemisphere of normal subjects 相似文献

This series of studies investigated the ability of literate adults to exploit communications options that are available to writers but have no counterpart in speech. Specifically it examined people's use of sketches when giving written directions to help a stranger cross town. When writing an informal letter to a friend most directions were given in prose paragraph style (Experiment 1). Almost no-one included a sketch, even if given a street map as an aid. Yet most subjects could draw adequate sketch maps (Experiment 2), and everyone said yes when asked whether they would include a sketch in a letter. So the previous choices were not constrained either by graphic skill or by judgements concerning the appropriateness of a sketch, When people were asked to 'design' the back page of a leaflet they still did not include a sketch (Experiment 3). Experiment 4 showed that any bias in the instructions was towards rather than against the use of sketches. The need to generate the sketch was removed in Experiment 5 where subjects composed the leaflet page from pre-formed sections that included alternative routes in both words and diagrams. Nearly all subjects now included a sketch in their directions. In case subjects previously, in haste, had not considered the possibility of including a sketch map, they were made aware of the drawing option by rating the usability of route information in a variety of communication styles immediately before writing their own directions (Experiment 6). People rated directions that included diagrams as significantly more usable, but still most subjects did not include a sketch in the directions they gave. So the communication styles that readers recognized as successful were not determining their choices as writers. It is suggested that, when giving written directions, inexperienced writers rely too heavily on how they would respond as speakers. 相似文献

To explore the potential of Rational Emotive Therapy (RET) with clients of Chinese background, a brief review is conducted
with respect to parallels between RET philosophy and some key components of Chinese culture and ways in which Chinese think.
Arguments are advanced as to why RET is particularly suitable for use within a Chinese cultural context. Issues involved in
using RET with Chinese clients are addressed including the appreciation many Chinese have for the logical and rational aspects
of RET, the most appropriate type of client-counselor relationship to facilitate RET therapeutic progress, appropriate ways
to dispute, and some cautionary words on the use of “emotive methods”. Areas where the RET counselor needs to be particularly
sensitive to the cultural background of the client are highlighted.
Charles P. Chen holds a master's degree in educational counseling and is currently a Ph.D. student and instructor in the Department
of Counselling Psychology at the University of British Columbia in Vancouver, Canada. His interests include cross-cultural
and multi-cultural counseling, career counseling, and group counseling. 相似文献

Abstract— Fourteen-year-old adolescents' behavior on a spatial-visual reasoning task was associated with self-report of their mothers' alcohol consumption during pregnancy, IS years earlier The task was arranged so that it was possible to evaluate the examinees' tendency to respond rapidly and less accurately, or slowly and more accurately The greater the mother's reported drinking, the faster and less accurately the adolescent responded The decrement in visual-spatial reasoning related to alcohol appears to be linked to a tendency toward impulsive responding 相似文献
