Clinical measures of impulsivity were administered to 33 incarcerated juvenile delinquents; scores were compared to the type and number of crimes committeed. The data revealed that impulsivity is a measureable construct among delinquent adolescents, but that impulsiveness is not necessarily related to either type or number of crimes committed.…

This study contrasted two possible relations between reflection-impulsivity and analytic or holistic modes of processing. Although impulsive children were more holistic in the classification task, they made more errors than reflectives on matching tests, regardless of whether the content favored holistic processing.

Temporal stability of play behavior and its consistency among toys differing in complexity was assessed by observing 40 eight-month-old infants. The relationship of stability of play to temperament was examined. Findings support the idea that behavioral consistency in infancy is similar to that reported for older children. (RH)

The purpose of this study was to determine the relationship between treatment-induced changes in academic achievement and social skills in elementary school-age children with attention-deficit hyperactivity disorder. A sample of 123 children in grades 1 through 4 with symptoms of inattention, impulsivity and/or hyperactivity, and significant…

The individual stylistic variations of creative potential and conceptual tempo were investigated in 61 preschool children. The Kansas Reflection Impulsivity Scale for Preschoolers (KRISP) was used to measure the reflective/impulsive (that is, creative tempo) dimension, and the Multidimensional Stimulus Fluency Measure (MSFM) was administered to…

A cross-age technique was used in two studies to extend understanding of cognitive style development and its cross-cultural generality. Chinese-American children were given the Matching Familiar Figures Test. Results were compared with existing data to determine the style development of children from other cultures. (PCB)

Experimental studies and clinical observations have indicated that right-hemisphere lesions produce impulsive talkative behavior. An exploratory study was conducted to investigate whether right-cerebral dysfunction would be evident in the intelligence test scores of talkative students with learning disabilities. The study with 28 children (ages…

Reply by Jerome Kagan to a recent article by Block, Gjerde, and Block (1986) which questions the validity of the construct of reflection-impulsivity. Kagan alleges flaws in the logic of the authors' (Block, Gjerde, Block) position and in the inferences drawn from their data. (Author/RWB)

Responds to the arguments and evidence adduced by Kagan (1987) in his reply to the Block, Gjerde, and Block (1986) study questioning the validity of the Matching Familiar Figures Test (MFFT) as a measure of "reflection-impulsivity." (Author)

Relates the problem-solving behavior of second, fourth, and sixth graders to conceptual tempo. Correlations with indices of strategic and efficient performance on a pattern-matching task confirmed that reflectives are more strategic than impulsives. A task-analysis identified the sources of inefficiency for each child and related these sources to…

This response to a critique (EC 609 161) of the authors' original paper (EC 609 160) on cognitive strategies in children with mental retardation answers specific points raised and makes explicit the theoretical issues underlying their work, including the strategy deficiency hypothesis of mental retardation, developmental issues in strategy…

This study examined the relationship between cognitive style and information processing in preschoolers, and described developmental changes in their performance on a central-incidental learning task. Sixty preschoolers, in two age groups (mean ages of 4-1 and 4-11), were administered tests of reflection-impulsivity, field dependence-independence,…

Sixty-five mothers of sexual abuse victims and 25 of their daughters were compared with 65 control mothers and 32 control daughters on the Eysenck Personality Questionnaire and the Leisure Interest Checklist. Results showed both study groups to be significantly less impulsive than their control counterparts. Victim mothers also presented…

In this article, the author discusses his list of seven precepts for good research in leadership in education. These precepts are: (1) The need to be clear about what research is; (2) The need to have regard to the applied nature of the field; (3) The need to differentiate but not to balkanise; (4) The need to be comprehensive and inclusive; (5)…

Activity level ratings and cognitive impulsivity were analyzed in relation to performance of second graders on several cognitive tasks and standardized achievement tests. In general, impulsivity-reflectivity had a far stronger effect on task performance and academic achievement than did activity level ratings.(RH)
