Tracing response parameter preparation strategies using transition times

Latencies were measured using a modified four-choice reaction time (4-CRT) test procedure; the responses comprised forward and backward displacements of left- and right-hand levers. Two stimuli were presented, separated by an interval (ISI) of 25, 165, 415 or 815 msec. S1 designated which response should be readied; and on 62% of occasions, S2 indicated that the prepared response should be executed immediately (same trials). During transition trials, S2 specified which one of the alternative responses should be substituted. Same conditions produced significantly shorter reaction times. Transition latencies varied depending on the modification required: changing direction proved easier than changing either hand or hand and direction. This is compatible with a response coding strategy in which limb is designated before direction. Latencies and exchange function analyses that preparations were discontinued after response selection; even at the longest ISI, there was no convincing evidence of preparatory motor programming.     

Influence of short-term memory codes on visual image processing: evidence from image transformation tasks.

Three experiments showed that phonological recording of visual stimuli in short-term memory (STM) affects coding in long-term memory (LTM) and therefore performance on tasks involving generation and manipulation of visual images of the stimuli. An image transformation task was devised. It consists of mentally subtracting a part of an image to discover in the remainder another object. In Experiment 1, Ss were required to learn a set of easily nameable visual stimuli and then perform the subtraction task on images retrieved from LTM. Performance was significantly better when initial learning was accompanied by articulatory suppression (AS). Experiment 2 confirmed that AS had no effect when the task was performed on an image of a just-presented stimulus. In Experiment 3, the nameability of the stimuli was manipulated. The results replicated the effect of AS for items that were easy to name but showed no effect of AS for stimuli that were difficult to name.     

My Disaster Recovery: a pilot randomized controlled trial of an Internet intervention

This pilot study tested the efficacy of the My Disaster Recovery (MDR) website to decrease negative affect and increase coping self-efficacy. Fifty-six survivors of Hurricane Ike were recruited from a larger study being conducted at the University of Texas Medical Branch at the first anniversary of the storm. Restricted randomization was used to assign participants to the MDR website, an information-only website, or a usual care condition. Group×time interactions indicated that MDR reduced participant worry more than the other conditions. A similar trend was also identified for depression. Both websites were accessed a small to moderate amount and participants reported mixed satisfaction for both websites. Although the effect sizes for worry and depression were in the moderate to large range, small sample size and timing of the intervention qualify the findings. These preliminary findings encourage further evaluation of MDR with a larger, demographically diverse sample and indicate that the MDR website might be helpful in reducing worry and depression.     

Dealing with Wicked Problems: Conducting a Causal Layered Analysis of Complex Social Psychological Issues

Causal layered analysis (CLA) is an emerging qualitative methodology adopted in the discipline of planning as an approach to deconstruct complex social issues. With psychologists increasingly confronted with complex, and “wicked” social and community issues, we argue that the discipline of psychology would benefit from adopting CLA as an analytical method. Until now, the application of CLA for data interpretation has generally been poorly defined and overwhelming for the novice. In this paper we propose an approach to CLA that provides a method for the deconstruction and analysis of complex social psychological issues. We introduce CLA as a qualitative methodology well suited for psychology, introduce the epistemological foundations of CLA, define a space for it adoption within the discipline, and, outline the steps for conducting a CLA using an applied example.     

Legitimating the legitimate: A grounded theory study of legitimacy work among Ethics and Compliance Officers

Organizations have responded to ethical scandals in part by creating the Ethics and Compliance Officer (ECO) role to help insure employee ethical and legal behavior. Because ECO work is so fundamental to behavioral ethics in organizations and we know very little about it, we conducted a grounded theory study to learn more. We learned that, although most ECOs were hired to help their organizations respond to external legitimacy challenges, ECOs face major legitimacy challenges inside their organizations. Facilitating conditions may reduce these challenges and help ECOs reach internal legitimacy. But, we also found that ECOs engage in what we term legitimacy work that relies on a number of tactics to help them gain legitimacy in the eyes of their constituents. We tie our findings to the broader legitimacy literature and draw implications for the behavioral ethics literature.
