Perception and Perceptual-Motor Processes in Children with Down's Syndrome

Some controversy exists regarding visual discrimination of form and its execution. The hypothesis that an inability to reproduce a display is not necessarily an indication that the display has been incorrectly perceived was examined in 34 mongol children (15 male, 19 female, mean CA 11.9 years) matched for MA with a control group of 25 normal children (10 male, 15 female, mean CA 4.2 years). Fifteen mongol children (six male and nine female) were identified who revealed perceptual deficits on block construction tests, and experimental work was conducted to determine the extent and nature of this impairment. The construction tests consisted of various displays made from five equal sized blocks. This was followed by an identification test consisting of two dimensional representations of the block designs printed on cards. All 15 mongol children were able to recognize and identify correctly a display from a selection which corresponded to a stimulus display, and 11 were able to go further and recognize a two dimensional representation of the stimulus. There was no significant difference between males and females. The experimental work reported here supports the hypothesis.     

The treatment of self‐efficacy among psychology and management scholars

Self‐efficacy has become a significant topic of investigation in both the psychological and organizational literatures. While psychology scholars typically insist efficacy beliefs should be treated as being domain specific, management scholars regularly treat efficacy beliefs as being generalized. The current study examines the relationships between generalized self‐efficacy, domain‐specific (i.e., work) self‐efficacy, and two work‐related outcome variables: leader–member exchange and learning. It was hypothesized that work self‐efficacy beliefs would fully mediate the relationships that may exist between generalized self‐efficacy beliefs and the work‐related outcomes under investigation. Data was obtained from state government employees (n = 133) located in the Southeastern United States, and structural equation modeling supported this hypothesis. Practical and research implications are discussed.     

Spatial breakdown in spatial construction: evidence from eye fixations in children with Williams syndrome

We investigated the role of executive and spatial representational processes in impaired performance of block construction tasks by children with Williams syndrome (WS), a rare genetic defect that results in severely impaired spatial cognition. In Experiment 1, we examined performance in two kinds of block construction tasks, Simple Puzzles, in which block faces contained a single color, and Complex, in which some block faces contained an arrangement of two colors. WS and control children were comparable in their ability to solve simple puzzles, and showed similar eye-fixation patterns, suggesting that basic executive processes were intact. However, WS children were severely impaired in their ability to solve complex puzzles. In these puzzles, WS children fixated the complex puzzle models and checked their partial solutions less often than normal children, but they were comparable in their ability to detect errors in their copies and almost exclusively made repairs to copies that were, in fact, incorrect. We conjecture that the abnormal fixation patterns were a consequence of impoverished spatial representations, rather than a cause of it. This conjecture was tested in Experiment 2, where we examined children's capacity to match and place individual blocks without engaging the complex executive processes required to carry out a complete puzzle solution. We found serious deficiency among WS children in both aspects of spatial representation. Moreover, estimates of the errors in representing the identity and location of model blocks derived from Experiment 2 provided a good account of the observed errors in the block construction task of Experiment 1.     

Capitalizing on the Self-Referencing Effect in General Psychology: A Preliminary Study

After reviewing the literature on the effect of personal relevance (self-schema, self-referencing effect, autobiographical significance, etc.), I implemented a constructivist narrative assignment for general psychology students. I hoped the assignment would enhance learning of and memory for psychological principles. Students wrote personal relevance papers in which they described psychological principles in their own words and provided examples of how the principles they chose were relevant in their own lives. Students assigned to write the papers produced higher exam scores. Moreover, student feedback revealed other benefits, including improved writing quality, higher grades, and increased motivation to learn.     

The influence of context on the assessment of family interaction: a clinical study*

A clinical study to compare clinically-observed with task-elicited family interaction was carried out as follows. Twelve families receiving family therapy were administered a series of tasks by tape-recorder. The therapist and an independent observer recorded interaction patterns in six dimensions (Alliance, Parenting, Marital Relationship, Communication, Affective Status and Boundary Integrity) and the results were compared with what was known clinically. Except for conflict the Task Interview revealed the main clinical features; however, it also revealed significant new information in all cases but one. The study has implications for clinical work.     

EFFECTS OF RELAXATION TRAINING ON PULMONARY MECHANICS IN CHILDREN WITH ASTHMA1

An experiment, designed to overcome shortcomings in previous work, was conducted to investigate the potential symptomatic benefits of relaxation training in the treatment of asthma in children. Fourteen chronic, severely asthmatic children received three sessions in which they rested quietly, followed by five sessions of relaxation training, and finally three sessions of relaxing as trained previously. Pulmonary function was assessed, in a manner far more definitive than in previous studies, before and after each session, and three additional times at 30-minute intervals thereafter. Tension in the frontales muscles, heart and respiration rates, and skin temperature and conductance were also monitored. Heart rate and to some extent muscle tension results tended to confirm the attainment of relaxed states. However, the lung function results failed to substantiate the previous, preliminary findings of a clinically meaningful change in pulmonary function following relaxation. The status of relaxation in the treatment of asthma was discussed.     

Measuring students' attitudes toward college education's role in addressing social issues

As service-learning projects have spread throughout academia, efforts to assess the service-learning experience have assumed a greater importance. The BERSI scale (Business Education's Role in addressing Social Issues) was developed as a measure of business students' attitudes toward social issues being addressed as part of a business education. As such, it was intended to be useful in assessing attitudinal outcomes of service learning. In order for the BERSI to be useful for nonbusiness students, the scale would need to be reconceptualized and revalidated. This study modified the BERSI items with a focus on college students in general rather than business students, making the resulting scale, College Education's Role in addressing Social Issues (CERSI), potentially helpful to service-learning researchers in a broader setting. The CERSI scale was then validated using standard techniques and normative data were reported.     

ATTITUDES INFLUENCING EMPLOYMENT OF THE HANDICAPPED

This study investigates the effect of existing attitudes on employment practices of two groups of Texas employers, the first employing visually handicapped persons, and the second employing physically handicapped persons. After personal interviews, all 24 participants were administered the Survey of Interpersonal Values (SIV) and the Action, Cognition, and Emotion Test (ACET). Among conclusions drawn from the findings were that employers of the visually handicapped indicate their willingness to hire persons with physical disabilities, that employers who show willingness to employ handicapped personnel at the professional level tend to value leadership traits in employees, that employers may not carry through with actual employment of the handicapped even though they communicate interest in and tolerance for these individuals, that employers' positive attitudes appear to relate significantly to positive experiences with handicapped workers, and that the larger the population center the more receptive the attitudes of employers toward the handicapped.
