Pathological left-handedness and familial sinistrality in relation to degree of mental retardation

The relationship between personal and familial hand preference and mental retardation was examined. Six unimanual tasks were performed by 232 subjects within four mental retardation severity groups. Family handedness histories were obtained. Right hand preference varied inversely with severity of mental retardation. The handedness of mentally retarded groups at the different functional levels paralleled, but tended much more to the sinistral, than that of the corresponding parent groups. The parent-proband handedness correlations were largely insignificant, especially in lower functioning groups. The findings support both pathological left-handedness theory and an association between brain damage causing mental retardation and familial sinistrality.     

Acceptability of positive and reductive behavioral interventions: Factors that influence teachers'' decisions

Treatment acceptability refers to individuals' judgments as to whether psychological treatment procedures are appropriate, fair, and reasonable for a given problem. In the present two-experiment study, experienced teachers' ratings of acceptability for positive (i.e., praise, home-based reinforcement, and token economy) and reductive (i.e., ignoring, response-cost lottery, and seclusion time-out) behavioral interventions were investigated. Using the Intervention Rating Profile (IRP) and a case study methodology to manipulate variables of intervention complexity and problem behavior severity, it was established that (a) teachers' acceptability ratings of both positive and reductive interventions varied with the severity of a target behavior, (b) the complexity of an intervention influenced teachers' ratings of acceptability, less complex or time-consuming interventions being rated generally more acceptable, and (c) mean acceptability ratings were significantly more favorable for positive than reductive treatments. These findings are discussed in the context of previous acceptability research and future investigations.     

Processing resource capacity and the comprehension of garden path sentences

Three experiments explored the relationship between verbal working memory capacity and the comprehension of garden path sentences. In Experiment 1, subjects with high, medium, and low working memory spans made acceptability judgments about garden path and control sentences under whole sentence and rapid serial visual presentation (RSVP) conditions. There were no significant differences between subjects with different working memory spans in the comprehension of garden path sentences in either condition. In Experiments 2A and 2B, subjects with high and low working memory spans were tested on the same materials at three RSVP rates. There were no significant differences between subjects with different working memory spans in the magnitude of the effect of garden path sentences at any presentation rate. The results suggest that working memory capacity, as measured by the Daneman and Carpenter (1980) reading span task, is not a major determinant of individual differences in the processing of garden path sentences.     

Relating infant temperament to learning disabilities

The role of infant temperament in the development of learning disabilities was at issue. As infants, boys with severe learning disabilities were found to be (1) lower in activity level, (2) more irregular, (3) less approaching, and (4) more negative in mood than normal boys. Discussion centered around conceptualizing learning disabilities as the outcome of a developmental process. Thus patterns of early parent-infant interaction are established, based in part upon the infant's temperament, that may evolve into a learning disability.The authors would like to express appreciation to George Diamond, director of Pupil Personnel Services for the Addison, Illinois, School District, for his help in obtaining these data.     

The perception of sex-inconsistent behavior

Sex-role perceptions were approached from an out-of-role attributional framework, with the predictions that out-of-role behavior would be rated more extreme than in-role behavior on sex-role stereotype scales and that out-of-role behavior would be seen as more internally determined. One hundred and twenty male and female college students heard one of four tapes in which the two stimulus persons (SPs), male and female, behaved in sex-role consistent or inconsistent behavior using the dimension of dominance-submission (DM-DF, SM-SF, DM-SF, DF-SM). The DF, compared to the DM, was attributed more masculinity and less femininity. The DF's behavior, compared to the DM, was seen as originating more from internal than situational causes.     

An interpretation of research on feedback interruption in speech

The controversial question of the scope of sensory control in the voluntary motor patterns involved in speech is examined by reviewing studies in which the auditory, tactile, and proprioceptive feedback channels have been distorted or interrupted. The author makes a case for open loop control of well-learned speech patterns under normal circumstances. The concept of internal feedback is introduced as a possible control system of skilled speech, whereas response feedback and external feedback are viewed as necessary for children developing speech or adults learning new speech patterns.     

Predictors of Risky and Precautionary Sexual Behaviors Among Single and Married White Women1

Risky and precautionary sexual behaviors were examined in a community sample of 260 single and married/cohabitating White women. Structural equation modeling was used to assess the ability of age, socioeconomic status (SES), marital status, religiosity, and 9 health belief constructs to predict risky sexual behavior with one's partner, using a barrier method of birth control, unintended pregnancies, and number of sexual partners in the past year. The pattern of results suggests that single White women appear to feel more vulnerable to HIV and STD infection and more likely to engage in risky sexual behavior than do married White women. The discussion focuses on the importance of sociocultural factors in understanding risk behaviors within the social context of relationship status, the complexity of the concept of risk reduction, and the need for going beyond the health belief model in order to develop different HIV prevention strategies for single and married White women.     

Family Reconstruction

Family reconstruction, as described by Virginia Satir, is important for its transformative possibilities. This therapeutic tool can integrate a person into the historical and psychological matrix of his or her family of origin. This article describes how a reconstruction can be accomplished in three hours by using certain steps and principles. A case study is provided illustrating these steps and principles, including the personal reflections of the participant group.
