Naming without knowing and appearance without associations: Evidence for constructive processes in semantic memory?

Abstract

This study describes a patient (SE) with temporal lobe injury resulting from Herpes Simplex Encephalitis, who displayed a previously unreported impairment in which his knowledge of associative and functional attributes of animals was disproportionately impaired by comparison with his knowledge of their sensory attributes (including their visual properties and characteristic sounds). His knowledge of man-made objects was preserved. A striking aspect of the present case was that the patient remained able to name many animals from their pictures, despite making gross errors in generating associative information about these same animals. This suggests that a semantic representation incorporating stored sensory knowledge may be sufficient for naming (at least for biological categories) and associative information may be unnecessary. Semantic knowledge may normally incorporate more information than is necessary for identification. SE's errors were found to be confabulatory and reconstructive in nature and it is argued that this aspect of his performance challenges passive conceptions of semantic memory couched in terms of a catalogue of stored representations. It is proposed that the patient's disorder affects a dynamic, constructive, and inferential component of his knowledge base, and that this component is sensitive to semantic category.     

THE BEHAVIORAL EFFECTS OF A PROCEDURE USED BY PEDIATRIC OCCUPATIONAL THERAPISTS

Pediatric occupational therapists often use specific activities associated with deep pressure touch as a modality when providing services based in sensory integration theory. This study investigated the effects of these activities contingent on choice responding. Initially, preference assessments identified that activities such as being swaddled in a blanket or sandwiched between halves of a therapy mat were potential reinforcers for each of the three participants. Then, the stimuli were presented contingently under a two‐response concurrent schedule. The results suggested that for each participant, the application of these activities functioned as a positive reinforcer. Given that such activities are often used in pediatric occupational therapy interventions, the clinical implications of these findings are discussed. Copyright © 2012 John Wiley & Sons, Ltd.     

The figural problem solving and problem finding of professional and semiprofessional artists and nonartists

The processes of finding a solution to a stated problem and those employed in formulating a problem prior to determining a solution strategy are implied by the behaviors observed in the manipulation of figural symbol systems. Sixty adult participants agreed to be videotaped while given two measures of spatial visualization, a figural problem‐solving activity, and two games which required defining a problem prior to producing a result. When groups, defined by their experience in producing ideas in art, were compared, traditional quantitative measures of performance yielded few significant differences. However, multivariate analyses of the observed qualitative variables resulted in significant differences. Theoretical and educational implications are discussed.     

Individualized Challenge Point Practice as a Method to Aid Motor Sequence Learning

We conducted two studies to investigate if and how: (1) the rate of skill acquisition was related to motor performance at retention of a serial RT task (Study 1); and (2) whether rate of skill acquisition and baseline performance could be used to design schedules of practice related to contextual interference (CI) to enhance motor learning (Study 2). In Study 1, a slower rate of skill acquisition of repeating sequences in practice was related to faster response times at retention. Based on performance in Study 1, three levels of individualized CI were created for Study 2. Compared to low and moderate levels of CI, the higher CI practice condition led to faster response times in retention. We conclude that an individualized ‘challenge point’, which generates high CI enhances motor learning by optimizing challenge.     

Predicting intolerance: The impact of parents’ own tolerance vs. social class and religious fundamentalism

The impact of parental intolerance, social class, and religious fundamentalism on the level of tolerance of post‐adolescent children is assessed on a sample of 205 mother‐father‐child triads. Social class plays an indirect role, and religious fundamentalism is shown to be the primary mechanism for the intergenerational transmission of intolerance. The concept of intolerance is extended so as to focus on reactions to deviant behavior. There is little evidence of specific sex linkage contrasts.     

A domain-specific validation of the core self-evaluations scale

Core self-evaluations have been recently proposed as indicating positive self-concept and as being predictive of various forms of subjective wellbeing. In an effort to further validate the Core Self-Evaluations Scale (CSES), structural equation modeling (SEM) was employed in three independent samples of university students to examine the extent to which scores on the Core Self-Evaluations Scale predicted two measures of university satisfaction. Good fit was found for models that also controlled for status in college, student major, class satisfaction, life satisfaction, college grade point average, and overall grade fairness. Statistically significant relationships corrected for attenuation by SEM between scores on the Core Self-Evaluations Scale and university satisfaction range from .24 to .37.
