Java experiments for introductory cognitive psychology courses

Interactive on-line experiments provide a unique and useful method for communicating material to students that is otherwise cumbersome and often confusing. The Java programming language is particularly suited for Internet-based programming applications of this sort because it bypasses many technical issues, including resource availability, security, and cross-platform compatibility. In most cases, topics appropriate to this medium of presentation should (1) not be easily demonstrated by other means, (2) represent an important finding in the field, and (3) be robust with respect to variations in both participants and equipment. The present paper outlines the integration of interactive experiments into an introductory cognitive psychology classroom, describing several experiments currently available on the World-Wide Web (WWW). Evaluation of the technical aspects of the technology as well as expansion of the format to other courses is discussed.     

The social environments of early infancy in Japan and the United States

The social environments of early infancy in Japan and the United States were compared in terms of the context of caregiving and the quality of the month-infant interaction. Mothers of 17 Japanese infants and 17 infants in the United States were interviewed in their homes about the experiences that they provided for their 4-month-old infants, and mother-infant interactions were recorded on videotape. Levels of parents' education were similar in both countries. The context of the infant's development varied substantially with culture. Mothers in the United States provided a greater variety of experiences on the HOME and care of Japanese infants tended to be more exclusively provided by mothers whereas care of infants in the United States was shared by fathers and other caregivers to a greater extent. Examination of behaviour frequencies during mother-infant interaction indicated that mothers in Japan provided their infants with more vocal input and more physical play than mothers in the United States and Japanese mothers were more vocally responsive to their infants' vocalizations.     

Differential effects of avoidant and attentional coping strategies on adaptation to chronic and recent-onset pain

Examined the effectiveness of attentional and avoidant coping strategies for somatic, behavioral, and psychological adaptation to clinical pain. Subjects were 30 chronic and 30 recent-onset pain patients who used either attentional or avoidant coping strategies in response to their pain. Based on a review of the coping literature, it was hypothesized that subjects with recent-onset pain would demonstrate greater adaptation (lower anxiety, depression, lower pain severity and somatization ratings, and higher levels of social activity) when employing avoidant rather than attentional strategies. Chronic pain subjects using attentional strategies were predicted to demonstrate greater adaptation than chronic pain subjects using avoidant strategies. The results supported this "time x strategy" hypothesis. Implications for pain treatment programs are discussed, and suggestions are made for matching pain duration with patient coping style.     

Implicit and explicit tests of odor memory reveal different outcomes following interference

Experiencing two odors as a mixture can later increase their perceived similarity when presented separately. Such an increase in similarity can be used as an implicit measure of how well participants remember the mixture. Three experiments tested the resistance to interference of this effect by first giving participants exposure to two 2-odor mixtures and then presenting each odor from one mixture (interfered pair) separately many times. After the latter interference phase, participants rated the similarity of the two odors in each pair. The experiments varied in terms of the number of initial exposures to the mixtures, the number of odor presentations in the interference phase, and the control conditions employed. No difference in similarity ratings for the interfered and non-interfered pair was found in any experiment. In contrast to the lack of interference with this implicit measure, an explicit measure of memory based on participants’ ratings of odor frequency revealed that they could recall to some degree that the interfered odors had been presented alone in the second phase. These results suggest that implicit memory for odor mixtures is highly resistant to interference and is consistent with a configural encoding account of this effect.     

Race Shapes Perceptions of Juvenile Offenders in Criminal Court1

We investigated the effects of defendant race, victim race, and juror gender on non‐African American mock jurors' perceptions of crimes committed by juvenile offenders. We predicted that mock jurors, particularly men, would render more pro‐prosecution case judgments when the defendant was African American than White. We also predicted that defendants would be judged more harshly when the crime victim was portrayed as White rather than as African American. Although there were few main effects of defendant race or victim race on case judgments, defendant and victim race by juror gender interactions revealed that men (but not women) demonstrated the predicted bias against African American defendants and victims. Explanations and implications are discussed.     

How the “Northern Irish” National Identity Is Understood and Used by Young People and Politicians

The conventional understanding of the nation within social psychology is as a category of people or “imagined community.” However, work within the discursive tradition shows that citizens tend to discuss nationhood in a variety of modes, including the use of nonhuman categories such as references to the physical landscape of the country. This article aims to give a more comprehensive overview of how young people understand the Northern Irish identity, a new and potentially inclusive national category in a divided society, and how politicians articulate it in rhetoric. In Study 1, students (N = 286) discussed this identity in 44 peer‐led focus groups. Thematic analysis of their discussions shows four distinct ways in which it is constructed: as a distinctive people, as an identity claim, as a “hot” political project, and as a “cold” or banal indicator of place. In Study 2, Members of the Legislative Assembly at Stormont (N = 49) responded to open‐ended questions about the Northern Irish identity. Each of the parties used different conceptualizations for rhetorical effect. These results give a deeper understanding of the multifaceted nature of national identity and its ability to promote political agendas.     

The role of experience in liking "read-to-drink" alcoholic beverages.

Ready-to-drinks (RTDs) are composed of an alcoholic component and a soft-drink base and are primarily consumed by a youth market. The authors explored whether liking and experience with an RTD soft-drink base predicts liking for the RTD. Participants (N=350) from ages 12 to 30 years sampled 3 RTDs and their respective soft-drink and alcoholic components. For milk- and fruit-based RTDs, liking for and familiarity with their soft-drink base was the best predictor of liking for and familiarity with the RTD itself. For the Coke-based RTD, familiarity with and liking for bourbon best predicted familiarity with and liking for the RTD. All of these effects were consistent across blind and nonblind testing. The authors' results suggest that where there is perceptual similarity between the RTD and its soft-drink base, these beverages may provide an easy transition into alcohol consumption for novice drinkers.     

The Arms Trade and the Slave Trade

We have abandoned the slave trade, and come to abhor it. Could the same happen with the arms trade? Even if we are not pacifists, and allow some use of force in self-defence, we must have serious ethical questions to ask about the trade in weaponry on which our economies are now so dependent. I distinguish the various forms these questions take for governments and individuals, and argue for some answers.     

THE GENERALITY AND SOCIAL VALIDITY OF A COMPETENCY-BASED SELF-CONTROL TRAINING INTERVENTION FOR UNDERACHIEVING STUDENTS

We evaluated the effectiveness, generality, and social validity of a modified version of a competency-based self-control package developed by Stevenson and Fantuzzo (1984). Three underachieving fifth-grade students were trained to use this intervention to increase their arithmetic proficiency. Results indicated that the intervention produced improved arithmetic performance. Moreover, all possible classes of generalization were evidenced for the participants. Social validity data showed that the children's arithmetic performance either surpassed or approached the mean performance of their higher achieving classmates. Additionally, teachers reported that the intervention was effective, appropriate for classroom use, and easy to implement.     

Social Cure Processes Help Lower Intergroup Anxiety Among Neighborhood Residents

Research in the social cure tradition shows that groups can reduce members' stress by providing support to cope with challenges, but it has yet to consider how this applies to the anxiety occasioned by outgroups. Research on intergroup contact has extensively examined how reducing intergroup anxiety improves attitudes towards outgroups, but it has yet to examine the role of intragroup support processes in facilitating this. The present article takes the case of residential contact, in which the impact of diversification upon neighborhood cohesion is hotly debated, but the role of neighborhood identification and social support from neighbors in facilitating residential mixing has been largely ignored. Our surveys of two geographically bounded communities in England (n = 310; n = 94) and one in Northern Ireland (n = 206) show that neighborhood identification predicts both well-being and more positive feelings towards outgroups, with both effects occurring via increased intragroup support. In studies 2 and 3, we show that this positive effect on feelings towards the outgroup occurs independently of that of intergroup contact and is further explained by the effect of neighborhood support in reducing intergroup anxiety. This suggests that social cure processes can improve intergroup attitudes by supporting group members to deal with the stress of intergroup interactions.
