USING STIMULUS EQUIVALENCE PROCEDURES TO TEACH NAME-FACE MATCHING TO ADULTS WITH BRAIN INJURIES

On pretests, 3 men with brain injuries matched dictated names of three therapists to written names, but did not match dictated or written names to photos, produce correct names in response to photos, locate offices given written names, or name therapists on sight. Match-to-sample training established conditional relations between dictated names and photos. Posttests showed the emergence of untrained conditional relations involving photos and written names, indicating development of three classes of equivalent stimuli (each containing a dictated name, photo, and written name). For 1 participant, conditional relations involving photos of office nameplates were also examined, but did not emerge pre- or posttraining. Two participants produced names orally when given photos and sorted written names and faces together after training; the 3rd participant was unavailable for these posttests. After training, 1 participant located and named all three therapists in their offices.     

The effect of individual differences in act prototypicality judgments on trait-behaviour correlations and cross-situational consistency

Individuals differ in their perceptions of actprototypicality. This study examined whether incorporating such individual differences enhances trait-behaviour correlations and provides stronger evidence for cross-situational consistency. Three hundred and fifty-three subjects rated the dominance prototypicality of 100 acts, indicated how often they performed each of these acts, and provided trait ratings of how dominant they were in general. There were substantial and reliable individual differences in prototypicality judgements over a 4–5 month period. A variety of weighting schemes were used to incorporate these individual differences, but none dramatically increased the trait-behaviour correlation. Similarly, incorporating individual differences did not increase the magnitude of cross-situational consistency correlations. However, incorporating individual differences did enhance the pattern of trait-behaviour and consistency correlations from less prototypical to highly prototypical acts. Differences in perceptions of act prototypicality thus do not affect the magnitude of the correlations that can be obtained, but they are useful in revealing theoretically meaningful patterns of relationships.     

Continuous attention: rationale and discriminant validation of a test designed for use in psychopharmacology

The continuous attention task (CAT) is a test designed to assess changes in attention due to a variety of factors, for example, drugs. Subjects view a series of 3x3 patterns of squares on a monitor screen, each displayed for 100 msec at intervals of 1.5–2.5 sec, and respond whenever two successive patterns are identical. For such a measure to be validr factors other than attention should be investigated, and shown not to be a factor in performance. Nineteen subjects took part in a study in which information-processing rate and recall of CAT figures was measured. The results showed that a viewing time of 50–60 msec was sufficient for 50% correct recognition of CAT figures, and that recognition with a masked presentation of 100 msec did not differ significantly from an unmaske presentation of 100 msec. Mean recall of CAT figures 2 sec after a 100-msec exposure was 98.2%. These results suggest that performance on the CAT is not limited by either information-processing speed or memory capacity, but is a valid measure of the ability to sustain attention.     

Assessing the relationship of Type A beliefs to cardiovascular disease risk and psychosocial distress

Investigators have begun to take a multimodal approach to the assessment and treatment of psychosocial risk factors for cardiovascular disease (CVD). For instance, cognitive responses have become the focus of contemporary research along with continued examination of overt Type A behaviors. Price (1982) has outlined a set of beliefs purportedly associated with Type A behavior and subsequent CVD risk. The current study examines the validity of this belief set as represented by a newly developed measure, the Type A Cognitive Questionnaire (TACQ). Subjects were 221 employed adults participating in a worksite CVD risk reduction program. They completed the TACQ as part of a pretreatment CVD risk screening protocol. As hypothesized, TACQ scores were significantly associated with Type A behavior, hostility, physiological mediators of CVD, and psychosocial distress. Discussion addresses continued refinement of the Type A belief construct.     

Recency effect in recall of a word list when an immediate memory task is performed after each word presentation

Subjects studied 12-word lists for free recall. During presentation of the lists, each word was followed by a supraspan sequence of digits, which the subjects tried to reproduce. This task, unlike those used in previous research with this continual distractor procedure, presumably taxed immediate memory capacity to the full. Nevertheless, the word recall data showed a pronounced recency effect. Moreover, the magnitude of the recency effect was found to be just as great with this task as with a more typical task in which the demands on immediate memory are likely to be fewer. These findings reinforce the emerging view that the recency effect need not be the product of immediate memory.     

A TEST OF SHAVELSON'S HIERARCHICAL MULTIFACETED SELF-CONCEPT MODEL IN A FILIPINO COLLEGE SAMPLE

Shavelson's hierarchical, multifaceted self-concept model (HMFM) has proven useful to educational and psychological researchers. The reliability and factorial validity of a well-known HMFM instrument - the Fleming-Courtney Self-Rating Scales (SRS) - were examined for a sample of 198 Filipino college students. Confirmatory factor analysis compared six structural models. A six-factor, oblique model that included two social factors (Social Acceptance and Social Anxiety) fit the data best, and a second-order factor analysis supported the hierarchical structure of the SRS. The men were significantly higher than the women on three self-concept scales, but the only large effect was for Physical Abilities, consistent with findings in a U.S. college sample. Results provided some support for the utility of both the SRS and HMFM for Filipinos.     

The "psychosomatic family" model: an empirical and theoretical analysis

Evolution of the Family Systems Paradigm has been constrained by the dichotomy between theory building and empirical research. This article integrates these two domains by presenting a theoretical analysis of the "psychosomatic family" model as it informs and is informed by an empirical research project. Forty families of children with Crohn's disease (CD), ulcerative colitis (UC), and functional recurrent abdominal pain syndrome (RAP) were rated during standard, videotaped family interaction tasks, lunch, and interview. Laboratory scores of disease activity were associated with triangulation, marital dysfunction, and total "psychosomatic family" scores. Disease activity was not significantly correlated with enmeshment, overprotection, rigidity, conflict avoidance, or poor conflict resolution. Thus, the marital/triangulation and enmeshment/overprotection/conflict clusters may be subcomplexes of the "psychosomatic family" complex. CD, UC, and RAP groups differed in the relations among particular family patterns and disease activity. A heuristic family-psycho-somatic model is presented to facilitate future research.
