Vibrotactile pattern discrimination and communality at several body sites

In a series of experiments, the effects of spatial layout on vibrotactile pattern perception were explored by testing the ability to discriminate between two sequentially presented patterns that share active elements in the same spatial locations. Two-dimensional displays were used in order to examine the functional relationship between discrimination performance and patterncommunality, defined as the sharing elements, on different body sites. Accuracy of discrimination judgments was inversely proportional to communality, regardless of the number of pattern elements. For compact arrays fitted to the finger, palm, and thigh, the effects of communality appeared equivalent. The similarity between finger and thigh functions is remarkable, considering the dramatic differences between these sites in receptor components and structure. When these data were compared with those from arrays with distributed contactors, performance was substantially better with well-separated pattern elements. Such findings help to explicate how information from apposed patterns can best be delivered to the skin through tactile communication systems.     

The Clown or Contrary Figure as a Counseling Intervention Strategy With Native American Indian Clients

Humor via the door motif in Native American Indian cultures can be pervasive and perverse. Helping professionals are alerted to down humor as a positive counseling intervention for this population. Background information, possible cautions, and illustrations are offered, with the need for additional empirical support strongly encouraged.     

The development of beliefs about spelling and their relationship to spelling performance

This study examined relations among spelling performance and students' beliefs about spelling, including self-efficacy for spelling ability, outcome expectancy for spelling, and attributions for good spelling across grades 4, 7, and 10. Spelling self-efficacy remained relatively constant across grades. Spelling outcome expectancies for adult life and school declined across grades, as did effort and ability attributions for spelling success, with a disproportional decrease in ability attributions between grades 4 and 7. Self-efficacy was the strongest predictor of spelling performance at all grade levels; attribution for ability entered into the regression for grade 4 students, while outcome expectancies for school and writing were more important in grades 7 and 10. Cluster analyses on the grade 10 sample showed that students with high efficacy as spellers and high outcome expectancy of spelling for writing were the best spellers, with the highest performance reserved for those who attributed good spelling more to effort than ability. The impact of spelling instruction on developing beliefs is discussed.     

Intelligence and the Frontal Lobe: The Organization of Goal-Directed Behavior

Basic to the study of individual differences is the concept of “general intelligence” or Spearman'sg.In this article we suggest thatgis largely a reflection of the control functions of the frontal lobe. A series of experiments investigates a phenomenon we callgoal neglect:disregard of a task requirement even though it has been understood and remembered. Subjectively it is as though the neglected requirement “slips the subject's mind.” Previously described in frontal patients, we show that goal neglect can also be seen in some members of the normal population. In line with conventional distinctions between controlled and automatic processing, eliciting conditions for goal neglect include novelty, weak error feedback, and multiple concurrent task requirements. Under these conditions neglect is linked closely togand extremely common after frontal lesions. Following many other models, we suggest that behavior in any task is structured by a set of action constraints or requirements, derived in part from verbal instructions and specified at multiple levels of abstraction. A frontal process of constraint or requirement activation is fundamental to Spearman'sg.     

Features Resembling Tourette''s Syndrome in Developmental Stutterers

Developmental stuttering (DS) may be related to the extrapyramidal motor system and shares many clinical similarities with Tourette's syndrome (TS), which is widely believed to be associated with extrapyramidal dysfunction. Twenty-two stutterers were examined for neuropsychiatric features commonly seen in TS, including tics, obsessive-compulsive behaviors (OCB), and attention deficit disorders. Eleven stutterers displayed motor tics, and symptoms of OCB were observed at rates similar to those seen in persons with TS. Few stutterers demonstrated significant attentional deficits. Findings are consistent with models suggesting extrapyramidal involvement in DS and raise the possibility that DS and TS are pathogenetically related.     

Repression-sensitization and emotion control

The internal structure of the Repression-Sensitization (R-S) Scale was examined by means of factor analysis. Following a scree test, four factors were extracted: lassitude/depression, extraversion/confidence, guilelessness/trust, and emotional lability. Concurrent validation using the Emotion Control Questionnaire and the Eysenck Personality Inventory showed that the factors extracted from the R-S Scale were related in predictable ways to existing personality constructs, but the results argue against the use of the overall R-S score as an index of emotional response style.

A short form of the Common Beliefs Survey III

Previous studies have shown that the Common Beliefs Survey III (CBS III) is an irrational beliefs inventory with satisfactory psychometric properties. We extended research on the CBS by examining this 54-item inventory for redundant material, and substantially abbreviated it without compormising its reliability or validity. This article describes the development of the new, 19-item short form (CBS19), convenient for clinical use, that preserves the psychometric properties of the original.     

A comparison of the personal values and operative goals of school psychologists and school superintendents

A survey of 96 school psychologists and 75 school superintendents throughout the state of Ohio showed the two groups to have generally similar personal value systems and to be in overall agreement in their respective rankings of school psychology goals. Both groups held the traditional school psychologist's goal of conducting individual testing to be lower relevance than acting as an internal consultant or resource person. Of those differences identified, superintendents assigned greater relevance to values which were consistent with their administrative concerns, while psychologists held values preferring individualism as more relevant. Superintendents held goals associated with increased learning efficiency and interacting with community agencies as more relevant, while psychologists assigned higher relevance to goals associated with parent-psychologist interactions.
