Pupillary changes during recall in children

Seven children aged 7–9 years were auditorily presented five-digit numbers for retention intervals of 0 and 10 sec. Pupil size was recorded during stimulus presentation, retention interval, and recall of items. Findings indicate that pupil dilation occurs during encoding and retrieval of stimulus items with pupillary constriction occurring during retention of the items. The pupillary change functions obtained with children were found to be very similar to those obtained with older subjects.     

Effects of response cards on student participation and academic achievement: A systematic replication with inner-city students during whole-class science instruction

We evaluated the use of response cards during science instruction in a fifth-grade inner-city classroom. The experiment consisted of two methods of student participation-hand raising and write-on response cards-alternated in an ABAB design. During hand raising, the teacher called upon 1 student who had raised his or her hand in response to the teacher's question. During the response-card condition, each student was provided with a laminated board on which to write one- or two-word answers in response to each question asked by the teacher. Frequency of active student response was 14 times higher with response cards than with hand raising. All 22 students scored higher on next-day quizzes and on 2-week review tests that followed instruction with response cards than they did on quizzes and tests that covered facts and concepts taught with the hand-raising procedure.     

The Racial Digital Divide: Motivational,Affective, and Cognitive Correlates of Internet Use1

The indisputable existence of a racial digital divide calls into question the democratizing potential of the Internet. Beyond issues of access to the technology are psychological factors that may influence Internet use. A survey of 787 college undergraduates—630 European Americans and 157 African Americans—who have similar access to the Internet was used to examine motivational, affective, and cognitive factors that may influence Internet use and contribute to the racial digital divide. Racial differences in Internet use were obtained, but were limited to e‐mail use. A model of Internet use is offered that considers motivational, affective, and cognitive antecedents and consequences of use.     

Empathy as a cognitive inhibitor of interpersonal aggression

The studies presented in this paper examined empathy, especially perspective taking, as a potential inhibitor of interpersonal aggression. The theoretical rationale for these investigations derived from Zillmann's [(1988): Aggressive Behavior 14: 51–64] cognitive excitation model. Study 1 revealed that dispositional empathy correlates negatively with self-reported aggression and with conflict responses that reflect little concern for the needs of the other party. Empathy also was positively related to constructive responses to interpersonal conflict (i. e., those that do involve concern for the needs of the other party). In Study 2, perspective taking was manipulated with instructions to subjects prior to participation in a reaction-time task designed to measure aggression. When threat was relatively low, subjects who were instructed to take the perspective of the target responded less aggressively than did those who had been instructed to focus on the task. Study 3 examined the effect of dispositional perspective taking on verbal aggression. Threat was manipulated in terms of the combination of provocation and gender of the interactants. As predicted, perspective taking related to aggression inhibition under conditions of moderate threat–for males under low provocation and females under high provocation. These effects were predicted and explained in the context of the cognitive-excitation model. © 1994 Wiley-Liss, Inc.     

Continued Participation in Youth Sports: The Role of Achievement Motivation

This study explored the antecedents of enjoyment and intention to continue in youth sports using the social-cognitive model of achievement motivation with the 2 × 2 achievement goal modification. Participants were 327 sports participants between 11 and 15 years of age. Individuals high in incremental beliefs reported greater enjoyment and intention to continue. This was perhaps due to endorsing mastery-approach goals. Individuals relatively high in entity beliefs reported relatively less enjoyment. This was perhaps due to endorsing performance-avoidance goals. These individuals also reported relatively less intention to continue regardless of their achievement goals. Findings could have implications for preventing dropout from youth sports.
