Factorial similarity of the WISC-R for Anglos and Chicanos referred for psychological services

Two- and three-factor principal factor solutions to the WISC-R (Wechsler, 1974) were compared across race for referred Anglo and Chicano children. Additional comparisons of these factor solutions were made with those for normal Anglo, Chicano, Black, and Papago students (Reschly, 1978, Note 1) and the WISC-R standardization sample (Wechsler, 1974). Substantial congruence occurred across race for both the two- and three-factor solutions, though the two-factor solution was clearly most appropriate for the present sample.     

An adaptive reference/test paradigm: Application to pulsed fluoroscopy perception

We developed an adaptive forced-choice method whereby reference and test presentations were alternated in order to minimize effects from variables such as subject attention level. In our demonstration example of an X-ray fluoroscopy perception study, we measured detectability of low-contrast objects in noisy image sequences and determined X-ray dose levels for equivalent detectability of identical contrasts for a new test acquisition method (fluoroscopy at 15 acq/sec) as compared with a reference (conventional fluoroscopy at 30 acq/sec). In preliminary experiments, we found a dose savings with the test method. We derived parameter uncertainties for the adaptive procedure and demonstrated their applicability with Monte Carlo simulations. Repeated experiments on a single subject demonstrated reduced standard errors due to the reduction of day-to-day variations. It is believed that the method can be applied in a variety of situations in which one needs to compare perception measurements.     

Perceived Believability Among Adolescents of Health Warning Labels on Cigarette Packs1

This study investigated the extent to which adolescents believe the health warning labels on cigarette packs, and the relationship of current smoking status and gender to the believability ratings. Subjects were 691 students in grades 5 through 12. MANOVAs revealed that, smokers, both male and female, reported significantly less belief in the validity of 3 of the health warning labels than nonsmokers. These findings support prior investigations which indicate that adolescent smokers are less likely to accept the specific health risks associated with smoking than nonsmokers. The results, however, also raise the question as to what value such health warning labels have as a deterrent to cigarette smoking.     

Separate Digits tests: A brief history,a literature review,and a reexamination of the factor structure of the test of memory and learning (TOMAL)

Following a brief history of Digit Span, a review of 27 articles, selected from 76, addresses the question of whether to scale Digits Forward and Backward separately. The review begins with studies involving Digits Forward, followed in turn by studies of Digits Backward and of both subtests. Finally, the loadings of four TOMAL subtests, Digits Forward and Backward and Letters Forward and Backward, undergo examination in the context of two, three, and four factor promax solutions, with corresponding varimax solutions provided for comparison. The analysis leads to several conclusions. Though Digits Forward and Backward show similarities, they load differently in the three and four factor solutions; Digits Backward also displays a spatial element, and perhaps a transformative element, not apparent in Digits Forward. Moreover, the differences between the two measures have important neurologic and diagnostic implications.     

Maximizing the therapeutic effectiveness of small psychotherapy groups

Little attention has been paid in the literature to the ways in which psychotherapy groups of fewer than five members can be led effectively. The conditions leading to small groups are presented, including both dynamic and circumstantial conditions arising in the institution, the group, and the therapist. The dynamics of small groups are described based on social psychology research and clinical observations. The paper concludes by presenting therapist and member characteristics as well as therapeutic techniques which contribute to the maximal effectiveness of groups with fewer than five members.     

Predictors of Hypersexual Behavior Among College Men and Women: Exploring Self‐Conscious Emotions

The authors examined self‐conscious emotions as predictors of hypersexual behavior among 235 college students. Among men, shame‐proneness and externalization predicted higher hypersexual behavior, whereas guilt‐proneness and detachment were associated with lower hypersexual behavior. Detachment predicted higher hypersexual behavior among women.

Brain plasticity and behavior

Although the brain was once seen as a rather static organ, it is now clear that the organization of brain circuitry is constantly changing as a function of experience. These changes are referred to as brain plasticity, and they are associated with functional changes that include phenomena such as memory, addiction, and recovery of function. Recent research has shown that brain plasticity and behavior can be influenced by a myriad of factors, including both pre- and postnatal experience, drugs, hormones, maturation, aging, diet, disease, and stress. Understanding how these factors influence brain organization and function is important not only for understanding both normal and abnormal behavior, but also for designing treatments for behavioral and psychological disorders ranging from addiction to stroke.
