The cognitive specificity of learned helplessness and depression deficits: The role of self-focused cognitions

Abstract

Four experiments assessed similarities and differences in learned helplessness and depression-related deficits in cognitive performance and self-focused cognitions. Subjects answered the Beck Depression Inventory (Beck, Ward, Mendelson, Mock, & Erbaugh, 1961), were exposed to no-feedback or failure in unsolvable problems, and their response time in a digit comparison task (with or without a memory component, with different number of digits, and different number of mental transformations) and self-focused cognitions were assessed. Learned helplessness and depression deficits were found in a memory task, and the deficits increased with the number of digits. Depression deficits also increased with the number of transformations, and were also found in the no-memory/two transformation condition. Finally, task-related worries were related to learned helplessness deficits, and task-irrelevant thoughts were related to depression deficits. Findings were discussed in terms of the cognitive specificity of learned helplessness and depression deficits.     

REM need in adolescents as indicated by resistance to REM deprivation.

The hypothesis that adolescents have an exceptionally strong need for REM sleep was tested by measuring their resistance to REM deprivation. Ten adolescents (aged 16 to 17 yr.) were compared with 12 young adults (aged 25 to 27 yr.) in a standard REM deprivation procedure. The adolescents had to be awakened significantly more times than the young adults; this is consistent with the hypothesis that adolescents have a greater need for REM sleep.     

Control-related beliefs and sleep characteristics of posttraumatic stress disorder patients

To examine correlations among chronic Posttraumatic Stress Disorder (PTSD), control-related beliefs, and sleep difficulties 7 PTSD casualities and 7 non-PTSD matched subjects were compared in their laboratory sleep patterns as well as in their beliefs about personal control over external and internal events in general and over sleep-related events in particular. Analyses indicated that PTSD casualties had poorer sleep and reported more doubts regarding their ability to control external and internal events than control subjects. Further, we found a significant association between perceived control and sleep difficulties. Results were discussed in terms of Horowitz's conception of intrapsychic processes related to PTSD.     

Some Common Characteristics of Latency-Age Suicidal Children: A Tentative Model Based on Case Study Analyses

ABSTRACT: Eleven latency-age (6 ½ to 12 ½) boys and girls who attempted or threatened suicide were investigated by means of the following information: intensive interviews, therapeutic meetings, direct observation in school, meetings with teachers, and survey of school records. The families of the children were also interviewed. In spite of the many differences between the children's personalities and backgrounds, some common dynamic features seemed to emerge: (a) There was a suicidal parent in the family, in most cases the mother; (b) Most of the families of these children were engaged in a major crisis, not necessarily centered around the suicidal child; (c) The children experienced demands by the parents to assume responsibilities which the children perceived as being beyond their capability; (d) There was a lack of satisfying relationships with adults; (e) Most children perceived death in a paradoxical way, believing that death was a need satisfying state yet fearing death; (f) The children showed strong positive strivings to say alive and were able to experience joy and happiness in spite of feelings of desperation and depression. A model based on the above multifaceted forces is presented. These forces consist of attractiveness of life, repulsiveness of life, attractiveness of death, and repulsiveness of death. Some of diagnostic and predictive uses of this model are elaborated.
