Preference for news as a function of familiarity

The study was designed to test the hypothesis that interest in information reaches a maximum when something novel is predicted about a well-known subject. The hypothesis predicts that news will be considered more attractive the more familiar its source or theme. This was confirmed in two experiments, where Norwegian and British students were asked to state their interest in reading news from thirty countries of varying familiarity (Experiment 1) or from correspondents in twenty-six capital cities (Experiment 2). Subjects also stated their preferences for reading general information about the same countries or cities, and indicated from which of these they would prefer to receive postcard greetings. The results show preference for news to be closely related to familiarity of country or city ( r =0.93 and r =0.91). General information and postcard preferences were as predicted, less directly related to familiarity.     

Preference as a function of absolute response durations

The durations of 2 responses, 2 categories of reinforced nondiscriminated interresponse times, were varied while their relative durations were held approximately constant, with the longer about 2 1/2 times longer than the shorter. Three pigeons pecked for food. Reinforcers for the shorter and longer responses were arranged by a concurrent variable-interval, variable-interval schedule. Preference for the shorter response increased when both were lengthened. These results, taken together with previous results for discriminated interresponse times, show that preference for the shorter of 2 responses depends on their absolute durations, whether they are discriminated or not and regardless of autoshaped key pecks that may occur in the discriminated case. Time-allocation-matching was not generally obtained. The results qualitatively agree with an associative learner, a computational processing model derived from a molecular analysis of behavior.     

Arithmetic achievement as a function of introversion-extraversion and teacher-presented reward and punishment

Following Eysenck (1967), Gray (1973) and Wakefield (1979), it was hypothesized that the arithmetic achievement of extraverts would be better than introverts in those classrooms in which teacher-presented rewards predominated, and the arithmetic achievement of introverts would be better than extraverts in those classrooms in which teacher-presented punishment predominated. Five classrooms were rank-ordered according to their ratios of teacher-presented reward to teacher-presented punishment. A total of 101 fourth and fifth grade students from the five classrooms were then administered the Junior Eysenck Personality Questionnaire (JEPQ) and an arithmetic pretest. Subsequent to 40 school days, the students were administered the arithmetic posttest. Partialling out arithmetic pretest scores, lie scale scores from the JEPQ, and total arithmetic raw scores from the Comprehensive Test of Basic Skills (CTBS), regression analysis of arithmetic posttest scores with the interaction of extraversion scores from the JEPQ and classroom rank-order of the ratio of teacher-presented reward to teacher-presented punishment yielded significant results supporting the hypothesis. Additional analysis indicated the presence of non-hypothesized interactions of the Psychoticism and Neuroticism scales of the JEPQ with reward-punishment and extraversion.     

Preference for modes of dispute resolution as a function of process and decision control

Research on procedural justice has suggested that the distribution of control among participants can be used to classify dispute-resolution procedures and may be an important determinant of preference for such procedures. This experiment demonstrates that control can be meaningfully divided into two components: control over the presentation of evidence and control over the final decision. The experiment placed subjects (law students and undergraduates) in a situation of conflict and varied two between-subjects factors: (1) Role, whether subjects expected to role-play third parties (law students) or litigants (undergraduates), and (2) Orientation, whether individuals focused on equity claims (appeals to a norm of fairness) or legal claims (appeals to a strict, legal interpretation of events). As a control, a third-party neutral-orientation condition was included. In addition, subjects were presented with four dispute-resolution procedures which varied in third-party control over the presentation of evidence (Process Control) and third-party control over the final decision (Decision Control) as within-subjects factors. Results revealed that both litigants and third parties preferred high rather than low third-party decision control. Litigants with an equity orientation preferred low third-party control over the presentation of evidence, particularly when third parties had high rather than low decision control. Third parties and litigants with a legal orientation preferred low rather than high third-party process control only when there was high third-party decision control. Litigant preferences were more affected by variation in process control than variation in decision control while third-party preferences were more affected by variation in decision control than in process control. As a check on external validity, military judges given a neutral orientation were asked to evaluate and express preferences for the four dispute-resolution procedures. Their results were not detectably different from those of the law students who role-played third parties in the main portion of the study.     

Affective state and preference for immediate versus delayed reward

Fifty-two 9-year-olds were randomly assigned to success and failure treatment conditions involving acceptance or rejection of a drawing made for an art show. In a pilot study, this treatment was shown to influence significantly subjects' affective states. Just after treatment, subjects were presented with choices between pairs of small immediate and large delayed rewards. As predicted, subjects who had experienced success chose more often the large delayed reward than those who failed (p < .02). Prior expectancy for success and sex were not significantly related to choice behavior. The influence of affective state on various parameters of the choice paradigm was discussed, and other evidence was cited indicating that affective state is a major determinant of self-gratification behavior.
