Response selection influences inhibition of return

Previous work has suggested that there may be a relationship between the magnitude of inhibition of return (IOR) and the number of possible responses in the perceptual‐motor task. To test this possibility, the present experiment used a display that contained four horizontally aligned cue/target locations. In different blocks of trials, subjects responded to the target either with a one‐response detection key press, a two‐response localisation key press, or a four‐response localisation key press. The results showed the largest magnitude of IOR was found in the one‐response condition and the least in the four‐response condition. These results suggest that IOR may be most effective in inhibiting relatively prepotent responses and the inhibitory effect weakens when responses require more intricate sensorimotor mappings.     

Positive priming: Locations containing relevant information are labeled accordingly

Individuals engaged in a location task where the relevancy status [relevant (stimulus) vs irrelevant (distractor) information] of these locations was reversed from one trial (prime) to the next (probe). The results produced by these reversals (Distractor-to-Stimulus and Stimulus-to-Distractor) indicated that both stimulus and distractor items are given relevancy status labels which participate in the future processing at the labeled locations. These findings support the view that selective processing involves both `facilitatory' and `inhibitory' components. Further, unlike identity tasks, the data indicated that neither the formation nor the subsequent use of these `location' labels (stimulus or distractor) is related to the presence of a response conflict.PsycINFO classification: 2330; 2340     

Building Trust in Business Schools Through Ethical Governance

This paper presents conceptual arguments to suggest that trust within organizations and trustworthiness of organizations are built through ethical governance mechanisms. We ground our analysis of trust, trustworthiness, and stewardship in the business literature and provide the context of business school governance as the focus of our paper. We present a framework that highlights the importance of knowledge, resources, performance focus, transparency, authentic caring, social capital and citizenship expectations in creating a basis for the ethical governance of organizations. A version of this paper was presented at the European Academy of Management, 2005.     

Effects of Ingroup Bias and Gender Role Violations on Acquaintance Rape Attributions

Two studies of ethnically diverse US college students from northern California examined whether ingroup bias and gender norm violations influence acquaintance rape attributions (Study 1, N?=?118; Study 2, N?=?140). Participants read vignettes depicting acquaintance rape and completed questionnaires. Victims were part of participants’ ingroup or outgroup. Study 1 manipulated the victim’s sexual history (chaste or promiscuous). Study 2 manipulated the victim’s alcohol use (sober or intoxicated). Ingroup victims were perceived more positively than outgroup victims if the victims were promiscuous or intoxicated. More guilt was attributed to rapists of ingroup victims than outgroup victims if the victims were promiscuous or intoxicated. Findings are examined in relation to ingroup bias and gender norm violations.     

Mechanical restraints as positive reinforcers for aggression

Research suggests that, in some cases, mechanical restraints may function as positive reinforcers. In this study, we conducted a functional analysis of severe aggression exhibited by an individual with a history of wearing arm splints. The results of this functional analysis demonstrated that his aggression was maintained by access to the arm splints. Copyright © 2008 John Wiley & Sons, Ltd.     

The Case for Creating a DBA Program – A Virtue-based Opportunity for Universities

Although efforts have been made to increase the opportunities for American-born minorities to obtain doctoral degrees in business, the actual number of business students who are American-born minorities has been extremely low. At the same time more than half of all PhD candidates in business schools are foreign-born. We suggest that business schools owe an ethical duty to provide role models for minority business students, and that this duty can be achieved by initiating Doctor of Business Administration (DBA) programs that can enable working professionals who are American-born minorities to obtain terminal degrees in business. We outline eight steps that can be taken to implement a viable and cost effective DBA program.
