Interactions Between Exogenous Auditory and Visual Spatial Attention

Six experiments were carried out to investigate the issue of cross-modality between exogenous auditory and visual spatial attention employing Posner's cueing paradigm in detection, localization, and discrimination tasks. Results indicated cueing in detection tasks with visual or auditory cues and visual targets but not with auditory targets (Experiment 1). In the localization tasks, cueing was found with both visual and auditory targets. Inhibition of return was apparent only in the within-modality conditions (Experiment 2). This suggests that it is important whether the attention system is activated directly (within a modality) or indirectly (between modalities). Increasing the cue validity from 50% to 80% influenced performance only in the localization task (Experiment 4). These findings are interpreted as being indicative for modality-specific but interacting attention mechanisms. The results of Experiments 5 and 6 (up/down discrimination tasks) also show cross-modal cueing but not with visual cues and auditory targets. Furthermore, there was no inhibition of return in any condition. This suggests that some cueing effects might be task dependent.     

Interculturalism: A new diversity ideology with interrelated components of dialogue,unity, and identity flexibility

Increased cultural diversity has led to considerable debate on how to best promote intergroup harmony within pluralistic nations. In the current research, we consider the nature of interculturalism, a new diversity ideology extensively discussed by political philosophers and policy-makers in Europe and beyond. Interculturalism consists of three interrelated components of dialogue, unity, and identity flexibility. Using data (N = 2,364) from three national surveys in two ethnically diverse nations (Netherlands and USA), we test a new measure of interculturalism and establish its independence from multiculturalism and assimilation. We then demonstrate that interculturalism predicts positive intergroup outcomes, over and above multiculturalism, and is in a theoretically meaningful way related to various criterion measures. Collectively, these studies establish the uniqueness of interculturalism from multiculturalism and demonstrate its promise for improving intergroup relations in culturally diverse nations.     

Bullying in elementary school, high school, and college

This study investigated the continuity in being a bully, victim, or bully-victim from elementary school through college in 119 undergraduates. Of 25 who bullied in college, 18 (72%) had been bullied in high school and elementary school. Of 26 bullies in college, 14 (53.8%) had been bullies in high school and elementary school. Of 12 bully-victims in college, 5 (41.6%) had been bully-victims in high school and elementary school. There were significant positive correlations between being a bully in college, high school, and elementary school, and being bullied in college and high school, and high school and elementary school, and between being both a bully and victim in elementary school, a bully and victim in high school, and a bully and victim in college.     

The impact of corrections for faking on the validity of noncognitive measures in selection settings

In selection research and practice, there have been many attempts to correct scores on noncognitive measures for applicants who may have faked their responses somehow. A related approach with more impact would be identifying and removing faking applicants from consideration for employment entirely, replacing them with high-scoring alternatives. The current study demonstrates that under typical conditions found in selection, even this latter approach has minimal impact on mean performance levels. Results indicate about .1 SD change in mean performance across a range of typical correlations between a faking measure and the criterion. Where trait scores were corrected only for suspected faking, and applicants not removed or replaced, the minimal impact the authors found on mean performance was reduced even further. By comparison, the impact of selection ratio and test validity is much larger across a range of realistic levels of selection ratios and validities. If selection researchers are interested only in maximizing predicted performance or validity, the use of faking measures to correct scores or remove applicants from further employment consideration will produce minimal effects.     

Imagination inflation is a fact, not an artifact: A reply to Pezdek and Eddy

Pezdek and Eddy (2001) claim to prove that imagination inflation is a spurious effect caused by regression to the mean (RTM). They make four predictions about what patterns of data would demonstrate a genuine effect for imagination versus those that would be explainable by RTM. We review each of those predictions, and demonstrate significant problems with them. We conclude that imagination inflation is a genuine effect, and that Pezdek and Eddy’s work has contributed to the growing research showing that when people imagine fictitious events from long ago, they become more confident that those false events were genuine experiences.     

The nature of perceived authority in the milgram paradigm: Two replications

Thirty-eight college students watched a short, edited version of Milgram’s documentary film, Obedience. They were then randomly assigned to one of two responseconditions: A Choice condition, in which they chose one of six explanations for the compliance of a subject depicted in the film, or a Likelihood condition, where they used a Likert-type scale to indicate the likelihood that each explanation elicited the subject’s compliance. The six explanations were based on French and Raven’s (1959) constructs regarding the bases of social power. We found that expert and legitimate power were judged as the most likely explanations in both conditions, replicating the findings of an earlier study that had used a different response format, i.e. rankordering the explanations, and thereby verifying the generality and robustness of the phenomenon.     

Gender and the Internet: Women Communicating and Men Searching

This research examined gender differences in Internet use and factors responsible for these differences. A sample of 630 Anglo American undergraduates completed the Student Computer and Internet Survey that contained questions about e-mail and Web use, and about potential affective and cognitive mediators of use. Based on a general model of Internet use, we predicted and found that females used e-mail more than did males, males used the Web more than did females, and females reported more computer anxiety, less computer self-efficacy, and less favorable and less stereotypic computer attitudes. Path analysis to identify mediators of gender differences in Internet use revealed that computer self-efficacy, loneliness, and depression accounted in part for gender differences, but that gender continued to have a direct effect on use after these factors were considered. Implications for realizing the democratizing potential and benefits of Internet use are discussed.     

Incremental validation of situational judgment tests.

Using 3 different samples, the authors assessed the incremental validity of situational judgment inventories (SJIs), relative to job knowledge, cognitive ability, job experience, and conscientiousness, in the prediction of job performance. The SJI was a valid predictor in all 3 samples and incrementally so in 2 samples. Relative to the other predictors, SJI's partial correlation with performance, controlling for the other 4 predictors, was superior in most comparisons. Subgroup differences on the SJI also appear to be less than those for cognitive ability and job knowledge, but greater than differences in conscientiousness. The SJI should prove to be a valuable additional measure in the prediction of job performance, but several additional areas of research are suggested.     

Irrelevant singletons in pop-out search: attentional capture or filtering costs?

The aim of the present study was to investigate whether costs invoked by the presence of an irrelevant singleton distractor in a visual search task are due to attentional capture by the irrelevant singleton or spatially unrelated filtering costs. Measures of spatial effects were based on distance effects, compatibility effects, and differences between singleton and nonsingleton target trials. The results show that the distractor only regularly captures attention when it is nonpredictive of the target position and unpredictably changes its features. When the distractor is antipredictive of the target position and the irrelevant features of target and distractor remain constant throughout the experiment, spatially unrelated filtering costs prevail. Further experiments showed that filtering costs accrue from distractor inhibition or target activation processes, which in turn can be modeled as instances of priming of pop-out. The present study thus clarifies the notion of filtering costs and modifies present accounts of the distraction effect. Moreover, the results also relate to research of intertrial priming by showing that priming affects the stage of attentional selection and depends on top-down attentional control settings.
