The effects of perceptual pretraining on concept identification and preference

The effects of perceptual pretraining on preferences and concept identification performance in five- and eight-year-old Ss were investigated. The results indicated that perceptual pretraining facilitated performance on a concept identification task with a non-preferred relevant cue for the five-year-olds, but not for the eight-year-olds. However, perceptual pretraining did not affect preference in either age group and Ss were as consistent in their preference responding before and after perceptual pretraining as was a control group that had not received perceptual pretraining. Preferences were highly consistent in both age groups over a one week period. Perceptual pretraining was interpreted to increase the usability of the less preferred dimensions for the younger Ss, and to leave the affective preference response unaltered in both groups.     

The development of conceptual and rote recall skills among school age children

One hundred eighty children from Grades K, 5, and 9 performed a recall task within one of four instructional conditions: serial recall; standard free recall; labeling free recall; labeling cued recall. The task required that Ss view and recall items from three successively presented sets of categorized pieture stimuli. Controls were imposed upon the associatice relatedness of items within sets so as to minimize the occurrence of associative responding during recall. The clustering data showed that kindergarten and fifth grade children are able to use conceptual skills to effectively mediate recall, but fail to effect these skills on a spontaneous basis in free recall. The results were discussed in line with the hypothesis that young children fail to engage in planful cognitive activity in recall tasks.     

Some variables affecting children's compliance with instructions

Children were given instructions to perform different tasks. Compliance was studied as a function of several variables: the prevailing pattern of reinforcement for different instructions, the availability of a competing reinforced activity, and the similarity among tasks. Rate of compliance tended to decrease when the probability of reinforcement for compliance decreased, or when a competing reinforced activity was available. Differential reinforcement over the tasks did not always produce discriminative responding even under favorable conditions. Novel instructions obtained compliance at the same rate as that for frequently repeated instructions, independent of the novel instruction's past or present reinforcement history. Greater discrimination in responding was found when tasks were less similar. Results imply that sets of instructions may form a response class, with characteristics similar to those found in studies of generalized imitation.     

Distinctive self and occupational member concepts in different occupational preference groups

This investigation attempted to test and extend selected aspects of Super's self-concept theory of career development. Four hundred twenty-eight male college student subjects, representing 39 college majors, selected their most-preferred occupational interest areas from a list of 14 factorially separable areas. The students described both themselves and their most-preferred occupational member concepts with Adjective Check List items. Individuals with demonstrably different self-concepts and occupational preferences displayed differences in the concepts that they held of members of their preferred occupational areas. Relatively distinct dimensions of similarity of self and occupational member concepts among students who preferred the same occupational area were also found.     

A biographical data analysis of career patterns in engineering

This study focuses on an instrument that appears useful for career guidance or job assignment purposes — the Biographical Data Blank. Responses of three groups of engineers (holding research and development, management, and nonengineering positions) to a life history questionnaire were analyzed. Results indicate that groups could indeed be differentiated using response patterns. In addition, items defining these patterns were related to demands of actual career paths chosen.     

The psychology of farming: A review of twenty-five years of research

If all of mankind is to have an adequate diet, we must both stabilize world population and increase markedly world food supply. Moreover, attaining any such increase in food supply may be as much a problem in vocational psychology (e.g. the skill, knowledge, openness to change, and motivation of farmers) as in agricultural technology. The purpose of this review is to further psychological work on agricultural productivity by listing and evaluating a cross-section of relevant articles since 1945. Because psychologists have largely ignored agriculture, most reviewed studies were conducted by other behavioral scientists. Studies are grouped according to three broad areas: (1) predictors of choice, success, and satisfaction; (2) adoption of recommended practices; and (3) communal agriculture.     

Expectation theories of decision making for duplex gambles

Complete tests of subjectively expected utility (SEU), subjectively expected value (SEV), expected utility (EU) and expected value (EV) theories were made for duplex gambles without measuring subjective probability or subjective utility. All gambles were hypothetical and offered on booklets. The duplex gambles consisted of winning gambles, which offered a chance to win a certain amount of money or to break even; and losing gambles, which offered a chance to lose a certain amount of money or break even.The results indicated that SEU, SEV and EU theories could not account for the strategies of 33%, 53% and 86% of the Ss respectively in the losing form of gambles, while EV theory accounted for 78% of the behavior of Ss.In the winning form of gambles, SEU, SEV and EU theory held for 77%, 65%, and 54% of the Ss respectively, while EV theory held for only 40% of the Ss. Suggestions for further research were made.     

The effect of vicarious punishment on prosocial behavior in children

Two experiments are reported dealing with the effects of vicarious punishment on prosocial behavior. In Experiment I, first and second grade females who witnessed a peer model being punished for a refusal to share (“nonsharing, punished”), shared more than an appropriate control group. Sharing was similarly heightened, however, in a group who witnessed punishment to the model which was not contingent upon any specific behavior (“punishment only”). Experiment II tested and confirmed the hypothesis derived from Experiment I that noncontingent vicarious punishment has a generalized inhibitory effect on antisocial behaviors. First, second, and third grade females were shown either the “nonsharing, punished,” “punishment only,” or baseline videotapes used in Experiment I. Subsequent to viewing the tapes, subjects in the “punishment only” condition helped the experimenter significantly more than did subjects in the “nonsharing, punished” and baseline conditions. The ability of existing theoretical treatments of vicarious punishment to account for these results is questioned.     

Subtraction and the solution of open sentence problems

This paper is concerned with the processes used by children in solving open sentence problems of the form x + u = y (Type 1) and u + x = y (Type 2). Three models for reaction times to these problems are proposed. The first assumes they are solved by an incrementing process, the second assumes a decrementing process, while the third assumes that the subject increments or decrements, depending on which is quickest. Two experiments designed to evaluate these models are reported. It is shown, by means of a series of regression analyses that the third model gives the best account of the success latencies to Type 1 problems. This model predicts that times will be a linear function of the minimum of x and y ? x. It is also shown that none of the models give an adequate account of the latency data for Type 2 problems. Some possible reasons for this difference are discussed, together with some evidence that indicates that Type 1 problems and ordinary subtraction problems are solved by the same process.     

The perception of consistency in attitudes

A study was conducted to test the hypothesis that when people change their attitudes they reduce the dissonance associated with the inconsistency of their new and previous positions by distorting their recall of their initial stand to make it consistent with their new attitude. Small groups of high school students discussed bussing, one of 30 pretested issues. An experimental confederate participated in each session with the task of effecting attitude change. After the discussion, the subjects' new attitudes were assessed and they were asked to duplicate their pretest scores. The results confirmed the hypothesis. Subjects distorted their recall of their initial stand on bussing so as to make it consistent with their new attitude. Such distortion allows persons to feel that their new position is the one they have always held. The subjects made such recall errors only on the bussing issue. Control subjects did not distort their original bussing attitudes.
