Hand preference and its flexibility according to the position of the object: a study in cercopithecines examining spontaneous behaviour and an experimental task (the Bishop QHP task)

The extant literature on manual laterality in non-human primates is inconclusive, plagued by inconsistent or contradictory findings and by disturbing methodological issues (e.g. uncontrolled influential factors, comparability issues). The present study examined hand preference and its flexibility in 15 red-capped mangabeys (C. t. torquatus) and 13 Campbell's monkeys (C. c. campbelli), two species that differ in their degree of arboreality. We investigated the influence of the spatial position of the object on hand preference for reaching. We considered spontaneous behaviour (reaching for food during daily feeding) and an experimental task: the QHP task. The QHP is a task that is used in humans. This is a simple reaching task that involves high spatial constraints on hand use. In our study, the subject had to reach for items that were placed on a semi-circle in front of it on five positions, including in the centre position, in the ipsilateral space and in the contralateral space. We assessed hand preference for reaching in front (baseline condition), and we examined how this preference changed when reaching in lateral positions. For reaching in front, about half of the subjects were lateralized and no group-level bias occurred, for both spontaneous and experimental conditions. When considering reaching in the lateral positions, we observed that the position of the object influenced hand use: individuals used the hand that was closest to the object. The results are discussed in relation to previous findings in humans and in non-human primates and regarding theories on handedness and flexibility of hand preference.     

Changes in verbalizations during sandplay: an empirical study

This is a quantitative study of an 11-year-old boy diagnosed with major depression who in all but one session made a sandplay. A computerized system was used to analyse the written verbalizations on four dimensions of positive and negative: emotions, contracts (psychosocial agreements, relationships, etc.), performance (behaviour) and rewards. It was hypothesized that the verbalizations made by the patient (recorded by the therapist) would become more positive and less negative during the course of therapy. The positive and negative values of the four dimensions were correlated with the session number. This was supported on two (performance & contract) of the four positive dimensions (statistically significant). The hypothesis that the negative dimensions would become less negative was supported on all four dimensions (statistically significant). Thus, six of the eight hypotheses were supported. This uninvestigated area of research illustrates verbal interactions between patient and therapist were an important aspect of sandplay therapy. Through reanalysing the sessions for quantitative content, written recording of direct quotes and observation of behaviour, data was entered into a valid and reliable coding system to quantitatively analyze the verbalizations. This analysis of verbalizations of the patient and observations made by the therapist indicates sandplay therapy is multifaceted.     

A Study of Black and White College Women

In an examination of career aspirations, 101 black and 530 white college women were asked to indicate their occupational and educational plans, important considerations for career choices, and their attitudes toward combining the roles of career and family. Results indicated that women who planned careers in male-dominated occupations had higher career and educational aspirations than women who desired careers in femaledominated occupations. Black women who planned careers in male-dominated professions showed high levels of aspirations, planned more education than was necessary for the desired occupations, and perceived less conflict in combining the roles of career and family than their white counterparts. There were few differences between black and white women in their attitudes toward the traditional roles of men and women. Those choosing female-dominated careers, however, had more traditional attitudes regardless of race. Implications of these findings for the influence of occupational gender dominance on career aspirations are discussed.     

THE EVALUATION OF A SEXUAL ASSAULT SELF-DEFENSE AND RISK-REDUCTION PROGRAM FOR COLLEGE WOMEN: A PROSPECTIVE STUDY

The present study evaluated the efficacy of a sexual assault risk-reduction program that included a physical self-defense component for college women ( N = 500). Program group women significantly increased their protective behaviors over the 6-month follow-up period compared to the waiting-list control group. However, there were no significant differences between the two groups regarding rates of sexual victimization, assertive communication, or feelings of self-efficacy over the follow-up periods. Program group women who were victimized during the 3-month follow-up period evidenced less self-blame and greater offender blame for their assaults than control group women who were victimized following the program. Given that program women evidenced a greater awareness of sexual assault at the end of the study than control group women, the difficulty in addressing the impact of programming on rates of sexual victimization is discussed.
