Examination anxiety: What the student counsellor can do

The student counsellor can help to minimise the impact of examination anxiety on students by running prophylactic groups aimed at helping students cope with and utilise their arousal in examination settings. In order to do this effectively, the counsellor must consider: (a) forming a working alliance with academic staff and (b) training paraprofessional staff to act as group leaders. A self-instructional programme is described, and counsellors are urged to keep up-to-date with theoretical and research developments in the area of examination anxiety.     

Visual search in multicharacter arrays with and without gaps

Subjects searched through briefly presented arrays of letters in a controlled order, indicating quickly which of two possible targets had occurred. Some arrays contained gaps—three missing letters. Reaction time (RT) and accuracy were both improved by a gap after the target; improvement was less when the gap preceded the target. To account for these results, a new model is proposed, one which calls for overlapping processing of successive array items. This is not a “hybrid” model, but a third alternative between the two extremes of serial (zero overlap) and parallel (complete overlap). Quantified, the overlapping model generates U-shaped serial-position curves and produces RT predictions in good accord with our data from arrays with and without gaps. The predicted functions for RT vs. array size are concave upward; however, for arrays of five or less they are virtually linear and not very different in slope for positive and negative trials. Although this model is primarily designed for RT, with some additional assumptions it can be extended to accuracy results.     

Childhood asthma: family therapy as an adjunct to routine management

A controlled trial of the effectiveness of family therapy for asthmatic children has been completed, and the results indicate that family therapy may have a part to play in the management of asthma. Our observations have shown that an interaction of psychosocial factors can have a significant effect on the course of the asthma by setting up a circular system which may ultimately lead to clinically intractable asthma, as well as intense emotional distress. Treatment is based on an understanding of the interactional model with the aim of interrupting the progressive sequence of events. A family approach is indicated when (1) emotional factors seem to be playing a significant part; (2) the asthmatic child is manifesting behaviour problems; (3) there is evidence of family psychopathology or (4) the asthma is not being reasonably well controlled with conventional methods of management.     

Rational-Emotive therapy and its contribution to careers counselling

While rational-emotive therapy is an influential therapeutic system in the USA, it has not received much serious consideration in Britain. Moreover, RET theorists and practitioners have not paid attention to its application to careers counselling. To correct these two situations, RET theory and practice is briefly discussed, and Crites' three-stage process model is used to show how counsellors can apply RET methods to careers counselling. Case material is presented to illustrate such applications.     

Stimulus control in a simple instrumental task: The role of internal and external stimuli

Two experiments using rats in a straight alley runway task tested the hypothesis that standard stimuli such as tones and lights (“external” stimuli) and schedule-generated aftereffect stimuli (“internal” stimuli) operate similarly and are similarly subject to the compounding rules specified by R. A. Rescorla and A. R. Wagner (In A. Black & W. Prokasy (Eds.), Classical conditioning II: Current theory and research. New York: Appleton-Century-Crofts, 1972). The experimental task was an instrumental analog of the classic blocking experiment (L. J. Kamin, In M. R. Jones (Ed.). In Experiment 1, blocking of an external discriminative stimulus by a different asymptotic discrimination was accomplished. In Experiment 2, blocking of an internal stimulus discrimination by an asymptotic external stimulus discrimination was obtained. The present results support the view that internal and external stimuli are indeed similar and function in the same manner with regard to blocking of stimulus control.     

An informational analysis of actors' and observers' belief attributions in a role-playing situation

An actor's belief in a proposition was inferred by both the actor himself and an observer on the basis of information concerning (a) the actor's preparation and delivery of a speech on the proposition to an unseen audience, and (b) the audience's belief in the proposition. The availability of this information to judges was systematically varied. The position advocated by the actor in his speech and the audience's opinion affected both the actor's belief in the test proposition and the belief attributed to the actor by a disinterested observer. However, neither effect depended upon whether or not other belief-relevant information was also available. These results were interpreted as more consistent with a summative model of information integration than with an averaging model. Actors' behavior had similar effects upon both actors' estimates of how the audience would judge their beliefs and observers' actual estimates of these beliefs. However, these effects were both greater than the effect of their behavior on their own estimates of their beliefs. The apparent strength of the audience's belief in the target proposition had a positive influence upon both actors' beliefs in the proposition and observers' estimates of actors' beliefs, but had a negative, or contrast effect upon actors' expectancies for how the audience would judge their beliefs. Results were more consistent with the differential perspective hypothesis of actor-observer differences proposed by Jones and Nisbett than with the hypothesis that actors and observers differentially weight the implications of their past experience in formulating their judgments. Results had additional implications for the assumptions that persons make when using their behaviors as indications of their beliefs.     

BEHAVIOR ANALYSIS OF MOTION CONTROL FOR PEDIATRIC NEUROIMAGING

Magnetic resonance imaging is a promising technological advance used for research and diagnosis of disease. The procedure has no risks, except when uncooperative patients require sedation. Four normal children participated in simulated scans to study the effects of (a) antecedent changes in the imaging environment and (b) operant conditioning of movement inhibition. Changing the environment can decrease movement, but operant contingencies were necessary to decrease movement to a level that, in most cases, would allow the procedure to occur without sedation.     

Time estimation and expectancies

The purpose of this research was to examine the influence of different types of expectancies on time estimation behavior. In Experiment 1, subjects were led to expect that a given number of trials would occur in a music perception task. In Experiment 2, expectancies concerning the duration of a given waiting period were varied. Results of both experiments indicated that the confirmation/violation of expectancies exerted a significant im acton4urationjudgments. When subjects received more/fewer trials than expected or waited for a duration-that-waslonger/shorter than expected, the total duration of these time spans was over- and underestimated, respectively. Conversely, time estimates were relatively accurate whensubjects' expectancies were confirmed. The results of Experiment 1 further revealedthat reaction time responses within-the-music perception task were also systematically influenced by the expected amount of activity. Results are discussed in terms of a framework that emphasizes the role of anticipatory attending on time estimation behavior.     

Effects of maternal employment patterns on adolescents' substance use and other risk-taking behaviors

Employment for mothers with school-age children has generated great concern regarding its possible harmful effects on adolescents and their families. We examined the influence of maternal employment on the risk-taking behavior of adolescents in two-parent families. Three hundred and eighty-nine high school students completed a 48-item survey in which they indicated their mother's and father's employment patterns, and their own risk-taking behaviors (e.g., substance use, driving while under the influence). Results showed no significant effects of maternal employment on adolescent risk-taking behaviors.     

Measurement of rational-emotive therapy in outcome studies

Outcome research has to date yielded little convincing evidence concerning the effectiveness and mechanisms of action of RET. One major cause of this problem appears to be the lack of empirical evidence to confirm that outcome studies have implemented RET as it is theoretically intended and with high quality. This paper reviews constructs relevant to the measurement of psychotherapy conditions in outcome studies (adherence, purity, differentiability, and quality), surveys the extent to which these constructs have been considered in prior RET outcome research, and offers recommendations for methodological improvements in future studies in this area.David A.
