Multi-component behavioral treatment of trichotillomania: a case study.

A 21-year-old female with a 13-year history of compulsive hair pulling was treated via a multi-component behavioral intervention strategy. Dependent variables included both quasi-direct behavioral frequency counts (i.e., number of hairs pulled) and physical trace, natural erosion measures (i.e. size of bald areas). Results indicated dramatic decrease in number of hairs pulled from treatment through 40 weeks post-initiation of baseline. These findings were discussed with regard to situational-specificity of trichotillomania and reliance upon experimenter-derived rather than subject-controlled data collection sources.     

Employee self-esteem: A review of the literature

Theories and empirical findings about self-esteem derived from the work role and its activities are reviewed. First, self-esteem is defined and problems inherent in its measurement are discussed. Theoretical perspectives relating self-esteem to the work role and activities are then outlined. Problems of a methodological nature, common to most of the evidence, are highlighted prior to reviewing the intrinsic and extrinsic job characteristics which influence self-esteem. The evidence pertaining to the moderating effects of chronic global self-esteem on such relationships is incorporated. The attitudinal and behavioral correlates of high employee self-esteem are then presented, followed by the influence of chronic self-esteem level on occupational choice. Suggestions are made for future research in line with the methodological and conceptual problems encountered.     

Self-observation and behavior change: Applications to academic and adjustment problems through behavioral consultation

Self-observation as a behavior change technique was implemented through behavioral consultation in a public elementary school system. The self-observation procedures were introduced to two subjects with academic problems (assignment completion) and two subjects with behavioral problems (disruptive talk and interruptions, respectively). In each of the four cases, self-observation resulted in improvement in client behavior. Results are discussed within the context of previous methodological issues in the self-observation literature and the relevance of self-observation as a therapeutic tool in school settings.     

Operationalizing the effect of the group on the individual: A self-attention perspective

The effect of the group on the individual is considered from the perspective of self-attention theory. It is proposed that group members will become more self-attentive, and thus become more concerned with matching to standards of appropriate behavior, as the relative size of their subgroup decreases. A simple algorithm, termed the Other-Total Ratio, is presented which numerically describes this effect of the group on the individual. An analysis of group effects on individuals' self-attention supports this perspective, as do analyses of the results of 42 previous studies in four other areas (conformity, prosocial behavior, social loafing, and antisocial behavior). This orientation to the effect of the group on the individual is linked to recent developments in self-attention theory and compared to Latané's social impact theory.     

Imagery ability and the identification of hands: A chronometric analysis

In a replication of Cooper and Shepard's (1975) study of hand recognition, it was found that individual differences in imagery ability had a significant influence on reaction times to such stimuli (Experiment 1). However, it was found (Experiment 2) that individual difference effects were only seen if prior instructions to use imagery were given to the subjects.     

Tactile spatial ability: Lateralized performance of deaf and hearing age groups

Hearing adults, 8- and 6-year-old children, together with deaf 9-year-old children, were tested on a unimodal haptic matching task. One additional group of adults was tested with a shorter stimulus presentation time. Data indicated that left-hand superiority was most evident in the performances of the older hearing children, and of the adults with the shorter presentation time. Hemispheric specialization was less noticeable for the younger hearing group, but the task may have been too difficult. A slight right-hand superiority was found in the performance of adults with long presentation time. This may reflect the simplicity of the task for these subjects. Deaf children did not show any clear hand differences, but were superior in overall performance to hearing children.     

Prosopagnosia and visual object agnosia: A behavioral study

A left-handed woman developed visual object agnosia, prosopagnosia, and visual disorientation after resection of the right occipital lobe. Color agnosia and alexia were absent. When asked to identify objects presented visually, the patient's errors represented visually related objects (underspecifications) or perseverations. Identification was facilitated when she observed the object being used in a natural way. Identification was impaired by surrounding the object with unrelated objects, decreasing the background illumination, decreasing the duration of exposure of the object to the patient, and probably also by decreasing the visual angle subtended by the object. In addition, there were disturbances of visualization (i.e., imaging in the absence of a visual stimulus) that paralleled the perceptual difficulties. We conclude that: (1) A deficit in visual perception, characterized by insufficient feature analysis of visual stimuli, was the basis of the visual agnosia in this case. (2) The visual agnosia could not be explained by (a) a vision-language disconnection syndrome, (b) decay of visual memory traces, or (c) deficiencies in the visual fields (pathologic Funktionswandel). (3) The ability to visualize (visual imagery) probably utilizes some of the same neural pathways used in perception. (4) The results in this case probably can be generalized to some but not all cases of visual agnosia; in particular, the deficit in most previously reported patients with prosopagnosia is similar to that of our case. However, agnosic alexia and color agnosia usually have a different neuropsychological basis.     

Statistical inference in personality research

Statistical significance, by itself, is not a sufficient condition for claiming that a hypothesis has been supported. Constructive replications are considerably more important. Unfortunately, classical (Fisherian) statistics are not easily adapted to sequential research strategies; their focus is the single experiment. For this reason, statistically significant results may be meaningless while a particular sequence of nonsignificant results may be quite important. Advice on how to overcome some limitations of classical statistical procedures is given, along with a compendium of “do's and don't's.”     

Alexia without agraphia: An experimental case study

A 51-year-old right-handed male experienced reading difficulty and an upper right visual field cut after a head injury. The patient's letter naming was impaired and word naming was painstakingly slow. Words were decoded in a letter by letter sequence and performance varied directly with word length. Apart from his reading difficulties the patient was linguistically competent. He was sensitive to manipulations of word frequency and orthographic regularity. He wrote spontaneously and could identify the written counterpart to a spoken word with relative ease. Computerized axial tomography revealed damage to the posterior temporal-parietal region of the left hemisphere.     

Economic deprivation and the quality of parent-child relations: A trickle-down framework

The trickle-down model of economic activity proposes that changes in economic activity permeate downwards from incentives or disincentives to business, which affect business income, investment, employment, and the absolute and relative economic deprivation of the poor. Within an extended trickle-down framework, this paper examines how these effects trickle further downwards to influence the quality of parent-child relations. Two cases are examined. First, deprivation is discussed as it trickles down to affect the parental image conveyed to children, and in turn perceptions od parents are examined as these predict children's problem behavior. Second, deprivation is discussed as it trickles down to affect parents' psychological well-being and child-rearing capabilities, particularly as manifested by the incidence of child abuse and neglect. The evidence to date converges to indicate that children in general are not necessarily aware of or sympathetic to the plight of those under economic strain. Economic deprivation may exacerbate conflict in the family, diminish children's perceptions of parents, and give rise to problem behavior in boys. Evidence also suggests that deprivation may be an antecedent of poor psychological well-being in adults and child abuse. Possibilities for a “bubble up” model of economic activity are explored together with directions for further research.
