Application of color displays to problems in the undergraduate laboratory

Some topics in psychology are difficult to master without dynamic visual displays. This paper describes a few applications of computer-driven color graphics displays in an undergraduate laboratory in neuropsychology. The paper includes the advantages, disadvantages, and cost of this approach, as well as student reactions and evaluations.     

AN APT PUNISHMENT FOR TOM JOAD: (RE)IDENTIFYING TOM JOAD FOR A MORAL JUDGMENT BASED ON THE PRA

Our basic intuition seems to suggest that the moral biography of an individual matters in our treatment of the individual. We do keep criminal records on file, and we do care about the moral progress of individuals. At times our desire to fix responsibility seems too strong, and in our zeal we invent a definite, metaphysical character on which to pin crimes. However, some moral philosophers have tried to redirect our attention to affix responsibility in a way that attends to actions, deeds done. Two ways to affix responsibility have been reviewed—the SR and the PRA. In the case of Tom Joad we could arrive at the conviction that Tom was responsible through use of either the SR or the PRA. In the end the difference was not that one method held Tom culpable and one exculpated him. The difference was seen in the way the PRA included the earlier commission of the same crime in its evaluation of responsibility. To include in the evaluation of Tom's murder of George the earlier murder of Herb is to entertain a definite theory about the relation of Herb's murderer to George's murderer. I have suggested one possible candidate for that theory, Derek Parfit's theory of person stages.     

PROSPECT (HE): An Evaluation of User Responses

The main features of PROSPECT (HE), a major new computer-aided guidance system for higher education institutions, are described. The results of its field trials within six higher education careers services show that the reactions of students and staff to the system are predominantly positive and that it has already established credibility with its users. There are, however, some 'tensions' between some of the principles on which the system is based: between matching and exploration; between coherence and flexibility; and between a phenomenological approach and an approach based on objective realism.     

The Janus face of power in intergroup contexts: a further exploration of the noblesse oblige effect

The authors examined the impact of power on in-group bias by manipulating group members' power over the in-group and power over the out-group as orthogonal factors. Each factor had 3 levels: 0%, 50%, and 100%. Participants were 216 male pupils (12-13 years old). Participants showed no in-group bias when they had 0% control over the in-group, strong in-group bias with 50% control, but less in-group bias with 100% control. Participants showed more in-group bias when they had 0% control over the out-group than when they had 50% or 100% control. The combination of these 2 main effects resulted in the noblesse oblige effect: Group members with complete control over both in-group and out-group expressed less in-group bias than did group members who shared control with an out-group.     

Control groups in psychosocial intervention research: ethical and methodological issues

This article summarizes a National Institute of Mental Health (NIMH) workshop that was convened to address the ethical and methodological issues that arise when conducting controlled psychosocial interventions research and introduces 6 thoughtful and inspiring papers presented by workshop participants. These papers, on topics ranging from informed consent to ethnic minority issues, reflect the depth and breadth of expertise represented by the multidisciplinary group of scientists and ethicists present at the meeting. More extensive follow-up, particularly from federal research applications and publications, of how investigators balance the need for strong research design with ethical considerations may help advance the science of psychosocial intervention research.     

An evaluation of a required computer-applications course for psychology majors

This study describes and evaluates a psychology course specifically focused on computer skills for undergraduate psychology majors. Learning by 136 undergraduates was evaluated on a 57-item objective test. Mean posttest scores were significantly higher than the mean pretest scores in all classes across all topic areas.     

Memory and memory confidence in obsessive-compulsive disorder

Pathological doubt, often found in individuals with obsessive-compulsive disorder (OCD), has been theoretically linked to memory deficits, but empirical evidence for such deficits has been mixed. In contrast, many studies suggest that individuals with OCD have low confidence in their memories. The present study aimed to build upon previous research by measuring memory accuracy and confidence in OCD using ecologically valid, idiographically-selected stimuli. Individuals with OCD (OCs), anxious controls (ACs), and nonanxious controls (NACs) were exposed to a set of objects that the OCs had identified as safe, unsafe, or neutral. Participants were then asked to recall as many objects as possible and to rate their confidence in each memory. This process was repeated 6 times, using the same stimuli for each trial. Contrary to hypothesis, no group differences emerged in memory accuracy. However, OCs' memory confidence for unsafe objects showed a progressive decline over repeated trials. This pattern was not observed among NACs or ACs. Furthermore, OCs with primary checking reported lower confidence in long-term memory than did OCs without primary checking. These results suggest that when OCs are repeatedly exposed to threat-related stimuli (such as repeated checking), their level of confidence in remembering these stimuli paradoxically decreases.     

Both exposure to a novel context and associative learning induce an upregulation of AKAP150 protein in mouse hippocampus

A-kinase anchoring protein 150 (AKAP150) is a multi-enzyme signaling complex that coordinates the action of PKA, PKC, and PP2B at neuronal membranes and synapses. We measured levels of AKAP150 protein in the hippocampus 6h after training mice in a contextual fear conditioning paradigm. In contextual fear conditioning mice learn to associate a context with a footshock presentation. Mice were divided in four experimental groups with different training protocols: naive, no footshock exposure, immediate footshock exposure, and footshock 3min after exposure to the context. We found that AKAP150 protein levels were increased upon exposing mice to the novel context independent of the training protocol. However, when the animals were habituated to the experimental context, only mice that learned to associate the context with the footshock showed an upregulation of AKAP150. We suggest that upregulated levels of AKAP150 contribute to processing the exposure to a novel context and associative learning.
