Processing from LVF, RVF and BILATERAL presentations: examinations of metacontrol and interhemispheric interaction 总被引:1,自引:0,他引:1
Observers indicated whether two successively presented drawings of faces were identical or differed in one feature (hair, eyes, mouth, jaw). The first face of each pair was presented at the fixation point and the second was presented to the left visual field-right hemisphere (LVF-RH), right visual field-left hemisphere (RVF-LH), or to both visual fields simultaneously (BILATERAL). On DIFFERENT trials the RT of correct responses depended on which feature differed and the pattern of feature location effects was significantly different on LVF-RH and RVF-LH trials. On BILATERAL trials the feature location effect was identical to that obtained on RVF-LH trials and significantly different from that obtained on LVF-RH trials. In addition, the percentage of errors and RT of correct responses were both higher on BILATERAL trials than on unilateral trials. Implications of these results are considered for the concept of "metacontrol" in neurologically normal humans and for models of interhemispheric interaction. 相似文献

The Lidvall neuroticism inventory is comprised of 25 questions referring to symptoms presumed to be connected with manifest neurotic anxiety. It was presented to 377 persons, an unscreened group with respect to neurotic symptoms, and a factor analysis with rotation to simple structure was performed.—Four factors could be identified: (1) manifest neurotic anxiety, (2) neurotic difficulties in interpersonal relations, (3) neurasthenic symptoms and (4) obsessive-compulsive symptoms. The factor scales were correlated with Neuroticism and Extraversion in MPI. Neuroticism was shown to be a heterogeneous factor. The correlation between Factor (2) and Extraversion was high. 相似文献

Categorization and multiple-cue judgment are similar tasks, but the influential models in the two areas are different in terms of the computations, processes, and neural substrates that they imply. In categorization, exemplar memory is often emphasized, whereas multiple-cue judgment generally is interpreted in terms of integration of cues that have been abstracted in training. In 3 experiments the authors investigated whether these conclusions derive from genuine differences in the processes or are accidental to the different research methods. The results revealed large individual differences and a shift from exemplar memory to cue abstraction when the criterion is changed from a binary to a continuous variable, especially for a probabilistic criterion. People appear to switch between qualitatively distinct processes in the 2 tasks. 相似文献

Traditional methods for quantifying sport performances are limited in their capacity to describe the complex interactions
of events that occur within a performance over time. The following article outlines a new approach to the study of actions
between players in team sports—mainly, soccer. Since the observational design is nomothetic, point, and multidimensional,
an observational and data-collecting instrument has been developed. The instrument is mixed and combines a field format with
a category system for game events, as well as an ad hoc instrument that considers the game actions of one or both teams, each
recorded according to the same criteria. The article also outlines a new approach to the analysis of time-based event records—in
this case, sports performance—known as T-pattern detection. The relevant elements of the T-pattern detection process
are explained, and exemplar data from analyses of soccer matches are presented to highlight the potential of this form of
data analysis. The results suggest that it is possible to identify new kinds of profiles for both individuals and teams on
the basis of observational criteria and a further analysis of temporal behavioral patterns detected within the performances. 相似文献

The authors examined the influence of preclinical dementia and impending death on the cross-sectional relationship between age and performance in tasks assessing episodic memory, visuospatial skill, and verbal fluency. Increasing age was associated with a general decrease in cognitive performance. In addition, those who were to be diagnosed with dementia or had died by a 3-year follow-up, were older, and performed at a lower level than the remaining sample across all cognitive tasks at baseline. Nevertheless, removal of the preclinical dementia and impending death groups from the original sample affected the cross-sectional age-cognition relations relatively little. This pattern of findings suggests that the biological aging process exerts negative influences on cognitive functioning beyond those resulting from disease and mortality. 相似文献

The aim of this study was to examine whether repeated testing with feedback benefits learning compared to rereading of introductory psychology key‐concepts in an educational context. The testing effect was examined immediately after practice, after 18 days, and at a five‐week delay in a sample of undergraduate students (n = 83). The results revealed that repeated testing with feedback significantly enhanced learning compared to rereading at all delays, demonstrating that repeated retrieval enhances retention compared to repeated encoding in the short‐ and the long‐term. In addition, the effect of repeated testing was beneficial for students irrespectively of working memory capacity. It is argued that teaching methods involving repeated retrieval are important to consider by the educational system. 相似文献

Combining study and test trials during learning is more beneficial for long-term retention than repeated study without testing (i.e., the testing effect). Less is known about the relative efficacy of different response formats during testing. We tested the hypothesis that overt testing (typing responses on a keyboard) during a practice phase benefits later memory more than covert testing (only pressing a button to indicate successful retrieval). In Experiment 1, three groups learned 40 word pairs either by repeatedly studying them, by studying and overtly testing them, or by studying and covertly testing them. In Experiment 2, only the two testing conditions were manipulated in a within-subjects design. In both experiments, participants received cued recall tests after a short (~19 min) and a long (1 week) retention interval. In Experiment 1, all groups performed equally well at the short retention interval. The overt testing group reliably outperformed the repeated study group after 1 week, whereas the covert testing group performed insignificantly different from both these groups. Hence, the testing effect was demonstrated for overt, but failed to show for covert testing. In Experiment 2, overtly tested items were better and more quickly retrieved than those covertly tested. Further, this does not seem to be due to any differences in retrieval effort during learning. To conclude, overt testing was more beneficial for later retention than covert testing, but the effect size was small. Possible explanations are discussed. 相似文献

Differences and similarities were studied in the functions of two different self‐injurious behaviors (SIB): nonsuicidal self‐injury (NSSI) and sex as self‐injury (SASI). Based on type of SIB reported, adolescents were classified in one of three groups: NSSI only (n = 910), SASI only (n = 41), and both NSSI and SASI (n = 76). There was support for functional equivalence in the two forms of SIB, with automatic functions being most commonly endorsed in all three groups. There were also functional differences, with adolescents in the SASI only group reporting more social influence functions than those with NSSI only. Adolescents reporting both NSSI and SASI endorsed the highest number of functions for both behaviors. Clinical implications are discussed, emphasizing the need for emotion regulation skills. 相似文献
