Effects of public and private deviancy on compliance with a request

A confederate requester asked subjects to write letters for an educational campaign after they had completed a battery of tests and received either deviant or nondeviant feedback. Half of the subjects were led to believe that the requester had knowledge of their test performance; the remaining half believed that the confederate did not know their test scores. Within these conditions, some subjects believed that complying with the request would involve future meetings with the requester while others were not led to anticipate any future interaction. As expected, deviants complied more than nondeviants replicating Freedman and Doob's (1968) results; however, neither the secret/known nor the future interaction variations produced effects. Contrary to the prediction that deviants are compliant because they wish to avoid mistreatment, secret deviants complied slightly more than known deviants. Compliance was discussed as instrumental in improving self-image.     

Choice times and Spence's discrimination learning theory

In two experiments, rats acquired brightness discriminations in a free-operant circular runway with two response alternatives. Both individual and group choice times revealed continuous changes that were not apparent in the discrete measure of choice. Two major assumptions of Spence's discrimination learning theory were confirmed: (a) learning is continuous, and (b) discriminative stimuli in simple discrimination tasks of both simultaneous and successive types are compounds with position elements as well as elements from the relevant visual dimension. The distinctive, consistent pattern of learning revealed by the choice-time measure suggests that position habits reflect a learning strategy in which the complex task is learned as a series of simpler ones.     

Occupational mobility as measured by Holland's theory of career selection

This study examined the occupational mobility of men ages 45–59 as measured by Holland's theory of career selection and its relationship to men in the work force. Stability was discussed in two distinct ways: (1) stability within a job, and (2) stability in the kind of work a man does over a career. In his research Holland concluded that Realistic and Investigative personality types would change personality type less often and have more stable job choices in comparison to other personality types. The results of this study supported these findings to some extent, but also concluded that stability in a personality type was strongly influenced by the number of jobs available in a particular personality type and the structure of the labor market demand. In addition the results showed that psychological concepts seem to be more important in changing jobs than in selecting initial jobs.     

The distracting effect of material reward: An alternative explanation for the superior performance of reward groups in probability learning

To determine whether the distraction effect associated with material rewards in discrimination learning can account for the superior performance of reward groups in probability learning, the performance of 144 school children (preschool, second, and fifth grades) on a two-choice successive discrimination task was compared under three reinforcement conditions (material reward, marker, and knowledge of results). The two events in the task had different frequencies of occurrence, as in probability learning, yet they appeared in a constant order to make 100% payoff possible. The subjects in the reward and marker groups learned the task more slowly, and the nonlearners among them used stereotyped alternation patterns to a greater degree than subjects in the knowledge-of-results condition. These findings suggest that a distracting effect of material reward is present in probability learning and may explain the superior performance of reward groups typically found in probability learning studies.     

Concomitant changes in classically conditioned heart rate and corneoretinal potential discrimination in the rabbit (Oryctolagus cuniculus)

Corneoretinal Potential (CRP) and heart rate changes were measured in a series of differential classical conditioning experiments in which the directionality of the heart rate response was related to (a) CRP acquisition, and (b) the certainty or uncertainty of the stimulus situation. The results suggested that heart rate decelerations were associated with stimuli that predict upcoming aversive events, while heart rate accelerations were associated with asymptotic CRP responding late in conditioning. These findings were interpreted in terms of (a) changes in general somatic activity, and (b) the cue properties associated with CSs which predict aversive events.     

Relationships among measures of visual imagery

As a step toward the development of an objective measure of visualization ability, five tasks which yielded seven separate measures were administered to 74 Ss and intercorrelated. The tasks were: paired associate recall improvement (RI), recognition memory (RM), the Bett's Questionnaire on Mental Imagery (QMI) as revised by Sheehan (1967a, b), a task calling for the production of visual images (PVI) where rated vividness and latency of image attainment were measured, and a task requiring the imagining of emotional scenes (ES) where rated vividness and rated anxiety were measured. The results indicated that although paired associate learning scores per se were related to RM, neither of the memory measures of visualization (RI and RM) were related to any of the other visualization measures. A cluster of intercorrelations was obtained among self-ratings of image vividness on the QMI, PVI and ES tasks. This cluster also included a measure of latency of report of “best image” attainable derived from the PVI task. None of the measures correlated with anxiety ratings on the ES task. These findings were discussed in relation to previous studies and the potential value of the latency measure as an adjunct measure of visualization ability was noted.
