Research in a wide variety of domains provides converging evidence for the psychological unconscious—percepts, memories, and other mental contents that influence experience, thought, and action outside of phenomenal awareness. Studies of preconscious processing indicate that two continua underlie conscious experience—one having to do with the quality of the stimulus event or its mental representation, and the other having to do with the cognitive resources brought to hear on the processing of that representation. However, evidence of subconscious processing violates these conclusions and suggests that something more is involved—perhaps a link between mental representations of events and of the self as the agent or experiencer of them. 相似文献

We used delayed multiple-baseline and multiple-probe techniques to assess the effects of self-evaluation training on the legibility of cursive handwriting. Five secondary special education students with difficult-to-read handwriting served as participants. All participants improved the legibility of their handwriting during self-evaluation training. A systematic withdrawal of the training package demonstrated maintenance of treatment effects. For the most part, the students' handwriting remained at least 90% legible to judges following the systematic withdrawal of the self-evaluation training. 相似文献

The notions of objects and attributes are essential to knowledge representation. Rudolf Wille’s concept lattices group objects and attributes into concepts, with concepts organized in a lattice, so that some concepts are subconcepts of others. This paper applies certain aspects of type theory to concept lattices in order better to facilitate the representation of knowledge inRoget’s International Thesaurus. Of particular interest is a formal analysis of functions providing concept lattices with a way of representing procedures and actions that currently are not present in the thesaurus. 相似文献

A collection of 4,741 word fragments that have a unique completion is described. All word fragments are specified by two letters (e.g.,__Q__U__can only be completed by the word LIQUEURS). The words completing these fragments range in length from five to nine letters. The fragments are unique with respect to a pool of 146,205 words, which helps rule out the possibility that obscure words could be used as a completion to the fragments. The collection of fragments as well as the words that complete them is available in ASCII format on computer disks or in printed form. 相似文献

Differences related to age and to specific neurological (Parkinsonian) damage were studied by contrasting, respectively, old (mean age 64 years) and young (27 years) subjects (N=15), and old-normal (N=15) and old-Parkinsonian (N=15) subjects. Both behavioral as well as psychophysiological dependent variables were employed. The behavioral measure was performance on a discrimination learning task, while the psychophysiological measures were based on habituation to a repeated tone stimulus and on a Pavlovian differential conditioning preparation. The behavioral task showed predominantly age-related differences, with the young learning faster. Another age-related difference was interpreted as showing a more insight-like learning process in the young. Response-bias (beta) values did not differ between groups. Age-related differences also emerged more clearly than specific-neurological-damage differences in the psychophysiological data. The older subjects manifested markedly less autonomic conditioning, which was probably due to a lowering of reactivity, as well as the emergence of habituation to the (loud-noise) unconditional stimulus. A correlational analysis of discrimination conditioning also yielded age-related differences. Most notably, reactivity played a greater role in conditioning in the old than in the young subjects. The results illustrated how psychophysiological measures can provide information that complements those provided by behavioral measures. 相似文献

ABSTRACT Subjects consisted of a sample of two cohorts of approximately 100 boys each whose behaviors were rated by their parents and teachers. Criterion variables included antisocial behavior, based on parent, child, teacher, and interviewer reports, and delinquency, based on parent and child reports in addition to cumulative arrest data taken from juvenile court records. The data suggest that mothers are focused on the daily, irritating behaviors of their sons. Teachers, on the other hand, appear to focus on a relatively small number of items (e.g., child physically attacks others, associates with deviant peers), and thereby provide ratings that are better predictors of delinquency and arrest. When the mothers' ratings were constrained to include only items that were salient for teachers, their predictive validity coefficients approached the magnitude of the teacher coefficients. 相似文献

Genetic and Environmental Effects on Openness to Experience, Agreeableness, and Conscientiousness: An Adoption/Twin Study 总被引:4,自引:0,他引:4

ABSTRACT Previous research has indicated that extraversion and neuroticism are substantially affected both by genotype and environment. This study assesses genetic and environmental influences on the other three components of the five-factor model of personality: Openness to Experience, Agreeableness, and Conscientiousness. An abbreviated version of the NEO Personality Inventory (NEO-PI) was administered to 82 pairs of identical twins and 171 pairs of fraternal twins reared apart and 132 pairs of identical twins and 167 pairs of fraternal twins reared together. Estimates of genetic and environmental effects for Openness and Conscientiousness were similar to those found in other studies of personality: Genetic influence was substantial and there was little evidence of shared rearing environment. Results for Agreeableness were different: Genetic influence accounted for only 12% of the variance and shared rearing environment accounted for 21% of the variance. Few significant gender or age differences for genetic and environmental parameters were found in model-fitting analyses. 相似文献
