Our two experiments investigated associations between cognitive representations of objects and hand-shape categories. Hand configurations were partitioned according to prehensility and the size of the contacting surface, resulting in the classes: pinch, poke, palm, and clench. Experiment 1 elicited object names in response to configuration-name cues, provided ratings of the relevance of each configuration to a set of objects, and probed for the functions determining such relevance. Cueing with a configuration class elicited an associated object category with substantial intersubject agreement, and vice versa. Both the object categories and the functions associated with the four hand-configuration classes differed substantially, although the same object could be associated to some extent with multiple configurations, given variations in function. Experiment 2 elicited the names of hand-configuration classes in response to unfamiliar forms, which varied systematically in depth and the size of the projecting picture-plane surface. The modal response, response time, and degree of intersubject agreement were directly related to these variables. These structural variables, however, did not adequately predict shaping responses to real objects, as ascertained from Experiment 1. The results have implications for cognitive representation of motor categories and hand shaping in response to objects. 相似文献

The purpose of this study was to test the effect of short-term training on reaching behavior in infants at the onset of reaching. The study was a single-blind, parallel group design, randomized controlled clinical trial. Thirty healthy infants were randomly assigned to a social control group (n = 15) or a reaching training group (n = 15). Infants began the study up to 3 days after the onset of reaching and were assessed three times across 2 days: pretraining (before training), posttraining 1 (after 1 session of training), and posttraining 2 (after 3 sessions of training). The reaching training group received 3 sessions of training by a physical therapist while the control group received a similar amount of time sitting in the therapist's lap. The data were analyzed using repeated-measures analyses of variance, and independent-samples tests with Bonferroni adjustments. Short-term training resulted in increased frequency of object contacts, shorter and smoother reaches, and improved hand positioning. The few short training sessions likely provided opportunities for infants to explore and learn to select movements from their existing movement repertoire. These results demonstrate that adaptive changes in infants' novel behaviors can emerge rapidly, and highlight the need for increased understanding of how to most effectively time early interventions. 相似文献

Context-dependent learning is a phenomenon in which people demonstrate superior performance in the context in which they originally learned a skill but perform less well in a novel context. This study investigated context-dependent learning in people with Parkinson's disease (PD) and age-matched nondisabled adults. All participants practiced 3 finger sequences, each embedded within a unique context (colors and locations on a computer screen). One day after practice, the participants were tested either under the sequence-context associations remained the same as during practice, or the sequence-context associations were changed (SWITCH). Compared with nondisabled adults, people with PD demonstrated significantly greater decrement in performance (especially movement time) under the SWITCH condition, suggesting that individuals with PD are more context dependent than nondisabled adults. 相似文献

The Trait Evaluation Index supposedly controls for social desirability of the alternatives in each triad by using forced-choice methodology. This claim was tested using 63 Ss asked to select the most desirable alternative in each triad. With a significant Chi-Square for an item interpreted as lack of control for desirability, 77% of the items yielded significant Chi-Squares. 相似文献

This article reports on two studies which examined the temporal stability of the personality disorder subscales from the Millon Clinical Multiaxial Inventory (MCMI). The scales demonstrated adequate stability in psychiatric inpatients (retested with an average of just over 1 year between testings). Furthermore, a separate sample of depressed inpatients assessed when depressed and 6 weeks later showed that the stability of MCMI personality scales was observed even after patients displayed an initial reduction in depression severity. Although stability is vital to the accurate assessment of personality disorders, both studies also found high retest correlations for the MCMI clinical syndrome subscales. In general, these results suggest that patients displayed similar symptom patterns over time, whether construed as personality traits or characteristic patterns of responding when symptomatic. 相似文献

The MMPI was administered to 29 college students under standard and ideal-self instructions in order to determine whether or not there is agreement as to what constitutes favorable adjustment. A profile analysis of the ideal-self responses yielding an intraclass correlation of .62 (p < .001). This result substantiates previous studies suggesting that an identifiable profile exists. Items changed between the self and ideal administrations were analyzed for their social favorability, interpretive ambiguity, obviousness, and scale membership. The first three factors were found to significantly influence responding under the ideal-self set. Implications of such item changes and of ideal-self profile were discussed. 相似文献

The development of programmed, actuarial interpretation of personality tests, especially the MMPI, is discussed. The presentation seeks to present a synoptic overview of the topic, including its more important trends, apparent present status, and possible consequences. Several commercially available systems are described, and an example of the output of each of three of them, in interpreting the same MMPI protocol, is presented for comparative illustration. 相似文献

The Rotter Incomplete Sentences Blank was administered to fifty out-patients at a rehabilitation center for narcotic addicts. There were twenty male heroin users, twenty male pill users, and ten female heroin users. Interscorer, intrascorer, and split-half reliabilities were all high. It was found that a cutting score of adjustment of 135 correctly identified 80 per cent of the male heroin users, 90 per cent of the male pill users, and 100 per cent of the female heroin users. 相似文献

Groups of Ss were matched with respect to their pre-experimental opinions regarding the value of psychological tests used by trained professionals to describe personality. Ss were then given either the Rorschach, TAT, FIRO-B, or Marlowe-Crowne Social Desirability Scale and were later given identical general personality interpretations supposedly based on the test results. An analysis of variance of Ss ratings of the accuracy of the personality interpretation indicated that neither the type of test S took nor whether the personality interpretation was presented as being derived “for you specifically” or “for people in general” had differential effects on Ss' acceptance of the interpretation; all groups rated the interpretation as being between “good” and “excellent.” 相似文献
