Some components of colour-word interference and their relationship with field dependence

It was suggested that the standard colour-word interference situation involves a number of distinct factors, each of which will contribute to the overall delay. Interference was analysed in terms of the delay associated with particular characteristics of different interfering stimuli; these measures were found to be unrelated, and were thus held to represent distinct components of the interference effect. Field dependence was primarily related to the component which was described as ‘perceptual distraction’.     

Assessing the Impact of a Media‐based Intervention to Prevent Intergroup Violence and Promote Positive Intergroup Relations in Burundi

The present study (N = 1074) examined the impact of a theory‐driven media intervention aimed at violence prevention and intergroup reconciliation in Burundi. We used a novel methodology utilizing audio‐based surveys to assess attitudes related to intergroup conflict and reconciliation among community members. We conducted a propensity score analysis to estimate the causal effects of the intervention by examining differences between listeners and non‐listeners of the radio dramas. The results indicated a positive effect of the intervention on several social psychological outcomes (tolerance, in‐group superiority, social distance, intergroup trust, responsibility attributions, trauma disclosure and competitive victimhood). However, listeners and non‐listeners did not differ in obedience toward leaders or historical perspective taking; and the results for active bystandership, one of the main foci of the intervention, were mixed. Furthermore, the results show that the impact of the intervention sometimes depends on listeners' personal experiences of victimization. Copyright © 2015 John Wiley & Sons, Ltd.     

Not Just “Study Drugs” for the Rich: Stimulants as Moral Tools for Creating Opportunities for Socially Disadvantaged Students

An argument in the cognitive enhancement literature is that using stimulants in populations of healthy but socially disadvantaged individuals mistakenly attributes pathology to nonpathological individuals who experience social inequalities. As the argument goes, using stimulants as cognitive-enhancing drugs to solve the social problem of poorly educated students in inadequate schools misattributes the problem as an individual medical problem, when it is really a collective sociopolitical problem. I challenge this argument on the grounds that not all types of enhancement have to be explained in medical terms, but rather at least one conception of enhancement can be explained in social terms—opportunity maintenance. Therefore, I propose that as a moral requirement we ought to explore whether stimulants could be a means of remedying underprivileged children's experiences of social inequalities that are borne from inadequate schools for the sake of increasing their chances for opportunities and well-being.     

Stimulus–response correspondence effect as a function of temporal overlap between relevant and irrelevant information processing

The stimulus–response correspondence (SRC) effect refers to advantages in performance when stimulus and response correspond in dimensions or features, even if the common features are irrelevant to the task. Previous research indicated that the SRC effect depends on the temporal course of stimulus information processing. The current study investigated how the temporal overlap between relevant and irrelevant stimulus processing influences the SRC effect. In this experiment, the irrelevant stimulus (a previously associated tone) preceded the relevant stimulus (a coloured rectangle). The irrelevant and relevant stimuli onset asynchrony was varied to manipulate the temporal overlap between the irrelevant and relevant stimuli processing. Results indicated that the SRC effect size varied as a quadratic function of the temporal overlap between the relevant stimulus and irrelevant stimulus. This finding extends previous experimental observations that the SRC effect size varies in an increasing or decreasing function with reaction time. The current study demonstrated a quadratic function between effect size and the temporal overlap.
