The effects of attention-directing training on recognition memory task performance of three-year-old children

Thirty-eight 3-year-old children served as subjects in an investigation of recognition memory in which schematic faces differing only in the orientation of the eyes were employed as stimuli. A pretest was administered to all children, after which the two experimental groups received training in either attention to the distinctive feature of the training stimuli (also schematic faces) by means of a matching task, or in labeling the faces according to how they looked (sleepy, happy, sad, mad) and in using the labels to perform a matching task. After the training session all children were given a posttest on recognition memory of the faces. The verbally trained group obtained significantly higher scores on the posttest than either the feature or control groups. These results indicate that although the children were able to discriminate the faces, evidenced in their ease of performance on the training tasks, they were not able to use this knowledge unless given training in attaching labels to the stimuli, which enabled them to store the information for later use. Results are discussed in light of Gibson's (1969) theory of the developmental interrelations of cognitive processes.     

RELATIVE EFFECTIVENESS OF TEACHER ATTENTION AND THE “GOOD BEHAVIOR GAME” IN MODIFYING DISRUPTIVE CLASSROOM BEHAVIOR1

A variety of behavioral procedures have been employed in recent years to modify disruptive classroom behavior. Such methods have been developed with the belief that curtailing disruptive behavior would strengthen positive classroom performance. In this study, two procedures, the good behavior game and the teacher-attention method, were compared to determine short-run effectiveness. Four teachers (two fourth-grade and two fifth-grade) implemented both methods in their classrooms over a five-week period. Presentation of methods was alternated in a counterbalanced design to control for order effects. Each of the four classrooms consisted of 25 students. A time-sampling procedure was used to record the presence or absence of disruptive behavior within 15-second intervals. Disruptive behavior was defined as any talking-out or out-of-seat behavior without permission. The results indicated that both procedures were effective in modifying disruptive classroom behavior, but that the good behavior game reduced disruptive behavior significantly better than the teacher-attention method. In addition, all teachers preferred the game to the teacher-attention procedure. This reaction seemed related to the effort involved in initiating the two activities. The good behavior game required less effort on the teacher's part. However, use of the game alone raises certain ethical considerations. One such issue involves abuse of peer pressure. Also, there is a possibility that negative rules may tend to promote resentment. Positively stated rules would ameliorate that problem. Another relates to the possibility that some teachers might be carried away by the ease of the game's implementation to the extent that behavior control becomes the primary objective in the classroom. As a result, one might consider use of the game to maximize short-term change, but then phase out this procedure in favor of another method (e.g., teacher attention) for long-run effects.     

The influence of evaluatee's sex on evaluations of a response on a managerial selection instrument

In this study 33 male and 22 female undergraduate students were trained and then asked to evaluate an in-basket response (with either a male or female respondent) on four dimensions: sensitivity, organizing and planning, decision-making, and written communications. Results indicated that the evaluatee's sex did not influence evaluations of the in-basket response. Female in comparison to male evaluators were significantly harsher in evaluating written communications. The absence of sex discrimination which sharply differed from the findings of several previous research studies is discussed in terms of the substantial amount of managerial related data provided by the in-basket technique.This report is based on a master's thesis written by the second author under the sponsorship of the first author and submitted in partial fulfillment of the requirements for the MA degree at Florida Technological University.     

Effects of expectancies of different reward magnitudes in transfer from noncontingent pairings to instrumental performance

In two experiments, rats received noncontingent pairings of two stimuli with food reward, one paired with small reward and the other with large reward, and received bar press training with large reward or with small reward. When the noncontingent stimuli (NS) were presented for test during subsequent rewarded bar pressing and during early extinction of bar pressing, responding for each group was faster in the presence of the NS which was paired with the same reward magnitude that group received in bar press training than to the NS which had been paired with a different reward magnitude. As extinction progressed, all groups responded more slowly in the presence of the NS which had been paired with the large reward than in the presence of the NS which had been paired with small reward. These results were interpreted as indicating that responding in the presence of an NS depends on: (i) whether the reward expectancy elicited by the NS has been conditioned to the instrumental response, and (ii) the relationship between the reward expected in the presence of the NS and that received in test.     

Morinaga’s paradox and figure-ground organization

Morinaga’s paradox of displacement is constructed by setting several copies of the two Mueller-Lyer figures one above the other. The Mueller-Lyer illusion is that the wings pointing out seem farther apart than wings pointing in, and Morinaga’s paradox is that when one looks down a column of wings pointing alternately one way and the other, they appear misaligned but in the opposite direction from the Mueller-Lyer illusion. The hypothesis of this paper is that the subject, under instructions to align the vertical array of wings, sets up a vertical figure-ground organization different from that used in judging the horizontal distance between wings, and that the two illusions are contingent upon the two organizations. The experiment showed that Morinaga’s paradox occurs when only one column of wings is shown, in agreement with the figure-ground hypothesis, and also shows that Morinaga’s paradox disappears when short line segments are introduced which disrupt the vertical figure-ground organization.
