The subjective experience of problem irresolvability and suicidal behavior: dynamics and measurement.

This article presents the dynamics and measurement of a relatively unstudied concept in children's and adolescents' suicidal behavior: the subjective experience of problem irresolvability (SEPI). This concept relates to the youngsters' sense of lack of control due to being pressured to resolve irresolvable problems within the family circle. The first study describes the construction and factor analysis of the SEPI scale as well as its relationship to suicidal tendencies, perceived parental care, and self-esteem. The second study presents a repeated factor analysis and the association between the SEPI scale and suicidal tendencies, hopelessness, depression, anxiety, and commitment to parents. The results suggest that the scale has a 4-factor structure with sound psychometric properties that distinguish successfully between suicidal adolescents on the one hand, and psychiatric and normal adolescents on the other. The SEPI was also found to be associated with the various studied variables.     

Children's appraisals of sex-typed behavior in their peers

Four experiments evaluated the effect of variations in sex-typed behavior in hypothetical peers on children's ratings of friendship. In all four studies, the children were heterogeneous with regard to social class, ethnicity, and race. In Experiment 1, children (71 boys, 90 girls) in Grades 3–6 read five stories about a target boy and in Experiment 2 (102 boys, 137 girls) about a target girl who displayed four sex-typed behaviors that ranged from exclusively masculine to exclusively feminine. In Experiment 1, boys preferred the exclusively masculine boy most as a friend. With each addition of a feminine behavior (and corresponding subtraction of a masculine behavior), the friendship ratings became increasingly negative. In contrast, the girls preferred the exclusively feminine boy most as a friend and, with each addition of a masculine behavior, the friendship ratings became increasingly negative. In Experiment 2, the converse was found although girls' ratings of friendship were less sharply affected by the target girl's sex-typed behavior than was observed for boys' ratings in Experiment 1. In Experiment 3, children (33 boys, 38 girls) in Grades K—2 were read three stories about a target boy, accompanied by detailed chromatic illustrations, whose four sex-typed behaviors were exclusively masculine, equally masculine and feminine, or exclusively feminine. The boys had significantly more favorable friendship ratings than the girls; however, in contrast to Experiments 1 and 2, the target boy's sex-typed behavior did not affect friendship ratings of either boys or girls. Experiment 4 (28 boys, 27 girls) repeated the procedure of Experiment 3 with children in kindergarten and Grade 1; in addition, the children made forced-choice friendship ratings for each of the three possible story pairs. In contrast to Experiment 3, boys' friendship ratings were affected by the target boy's sex-typed behavior, as observed in Experiment 1, but girls' friendship ratings were not. However, in the forced-choice situation, the boys significantly preferred the exclusively masculine boy whereas the girls significantly preferred the exclusively feminine boy. The results were discussed in relation to the influence sex-typed behavior has on modifying the effects of a peer's sex on affiliative preference and sex differences in appraisals of cross-gender behavior, including the concept of threshold effects.     

The effects of the reach to recovery program on the quality of life and rehabilitation of mastectomy patients

The purpose of this study was to assess the effectiveness of the Reach to Recovery Program of volunteers sponsored by the American Cancer Society. Effectiveness was defined as enhancing the quality of life and rehabilitation of women who had had a mastectomy, through increasing knowledge of rehabilitative procedures, post-surgery activities and level of self-esteem. The investigation was held in twelve community hospitals in Northeastern Massachusetts. Results of the investigation are reported here. It is recommended that post-operative teaching regarding proper management of rehabilitation procedures should be increased and that Reach to Recovery should be available to every woman who has a mastectomy.     

The internal clock: Electroencephalographic evidence for oscillatory processes underlying time perception

It has been proposed that temporal perception and performance depend on a biological source of temporal information. A model for a temporal oscillator put forward by Treisman, Faulkner, Naish, and Brogan (1990) predicted that if intense sensory pulses (such as auditory clicks) were presented to subjects at suitable rates they would perturb the frequency at which the temporal oscillator runs and so cause over- or underestimation of time. The resulting pattern of interference between sensory pulse rates and time judgments would depend on the frequency of the temporal oscillator and so might allow that frequency to be estimated. Such interference patterns were found using auditory clicks and visual flicker (Treisman & Brogan, 1992; Treisman et al., 1990). The present study examines time estimation together with the simultaneously recorded electroencephalogram to examine whether evidence of such an interference pattern can be found in the EEG.

Alternative models for the organization of a temporal system consisting of an oscillator or multiple oscillators are considered and predictions derived from them relating to the EEG. An experiment was run in which time intervals were presented for estimation, auditory clicks being given during those intervals, and the EEG was recorded concurrently. Analyses of the EEG revealed interactions between auditory click rates and certain EEG components which parallel the interference patterns previously found. The overall pattern of EEG results is interpreted as favouring a model for the organization of the temporal system in which sets of click-sensitive oscillators spaced at intervals of about 12.8 Hz contribute to the EEG spectrum. These are taken to represent a series of harmonically spaced distributions of oscillators involved in time-keeping.
