Skill-set,success outcome,and mania as determinants of the illusion of control

The illusion of control, the tendency for individuals to approach chance tasks with skill-appropriate strategies, was studied. Subjects premeasured on a mania scale were classified as either high (HM) or low (LM) in mania. In the first phase of the study, HM and LM subjects performed 30 trials on either a skill (verbal associates) or chance (coin-toss) task and were given either 20, 50, or 80% success feedback. After Task 1 was completed, subjects filled out an attribution questionnaire. In the final phase of the study, subjects anticipated 30 more trials either on a skill or chance task. Subjects' predicted successes were measured. It was hypothesized that predicted successes on anticipated skill and chance tasks would be affected more by outcomes on a previous skill task than by outcomes on a previous chance task. The results for the anticipated skill task directly supported the hypothesis. On the anticipated chance task, the hypothesis was confirmed for HM subjects only. The results are discussed in terms of how previous skill experiences may induce a set to control ungovernable situations for individuals with manic reactions.     

The role of dissimulation and social desirability in the measurement of moral reasoning

A series of studies investigating the psychometric and conceptual properties of the Survey of Ethical Attitudes (SEA), a paper-and-pencil measure of moral reasoning, is reported. The results of these studies indicate that the scale is clearly susceptible to the influence of response dissimulation in the form of both role-playing and impression management, and is also confounded with sources of stylistic variance in the form of social desirability. Previous proposals concerning the relationships among moral development, moral reasoning, and personality structure are reviewed in light of these findings, and an alternative conceptualization of the measure in terms of political and social attitudes is offered.     

Lateralization for reading musical chords: Disentangling symbolic, analytic, and phonological aspects of reading

It has been repeatedly shown that the left hemisphere (right visual field) is superior to the right hemisphere (LVF) in reading English, a bias possibly due to any or all of three confounded factors: (1) the symbolic nature of the coding system; (2) the analytic requirements of the decoding process; and (3) the phonological associations of the elements. Recent work on reading Japanese ideograms (Kanji) disentangles (1) from (2) and (3), but leaves the latter two confounded. We further disentangle (2) and (3) by examining visual field preference for reading musical chords, representatives of an analytic, nonphonological symbol system. The strong RVF advantage is interpreted as indicating that the left hemisphere is dominant for reading an analytic symbol system that is not phonologically based. We conclude that the left-hemisphere advantage traditionally found for reading phonological symbols is due to their analytic nature in addition to any effect due to their linguistic association.     

The use of teachers as behavioral observers

The effect of using teachers as behavioral observers on both student and teacher behavior was examined with eight teachers and 32 elementary school children. The frequency of prompts (but not praise or criticism) to those students observed by the teacher increased significantly from nonobserver to teacher observed experimental phases. In addition, students observed by the teacher showed more change in appropriate behavior than students who were not observed. The significance of these findings for research and therapy is discussed.     

Considerations in the choice of interobserver reliability estimates

Two types of interobserver reliability values may be needed in treatment studies in which observers constitute the primary data-acquisition system: trial reliability and the reliability of the composite unit or score which is subsequently analyzed, e.g., daily or weekly session totals. Two approaches to determining interobserver reliability are described: percentage agreement and "correlational" measures of reliability. The interpretation of these estimates, factors affecting their magnitude, and the advantages and limitations of each approach are presented.     

COMPARING TREATMENT TACTICS WITH A HYPERACTIVE PRESCHOOL CHILD: STIMULANT MEDICATION AND PROGRAMMED TEACHER INTERVENTION1

Two treatment tactics, food and praise contingent on appropriate play and varying doses of methylphenidate (Ritalin), were evaluated for their effects on a preschool child's activity changes. In addition, other social, verbal, and academic behaviors were monitored to examine possible side effects of the two treatment tactics. Fewer free-play activity changes occurred during contingent reinforcement phases while medication had variable effects: increasing attention to tasks but, at higher doses, decreasing intelligibility of speech and responsiveness to mands. The study outlines a replicable model for comparing medication with alternative behavioral strategies to control hyperactivity and enhance skill development.     

Visual-feature and response components in a picture-word interference task with beginning and skilled readers

A series of four experiments is reported in which reaction times for naming line drawings were analyzed as a function of the similarity of the print superimposed on the drawings to the printed label for the drawing. This effect was studied as a function of grade level (ages 6, 8, and 11 years) and, hence, reading experience. The studies were designed to determine more precisely the characteristics of the stage of visual feature analysis of word identification and to examine response competition factors in this interference task. Results indicated that a combination of end letters and word shape was important for word identification and that response articulation was a significant distinct interference component in this task.
