Asynchronous perception of motion and luminance change

Observers were asked to indicate when a target moving on a circular trajectory changed its luminance. The judged position of the luminance change was displaced from the true position in the direction of motion, indicating differences between the times-to-consciousness of motion and luminance change. Motion was processed faster than luminance change. The latency difference was more pronounced for a small (116–134 ms) than for a large luminance decrement (37 ms). The results show that first-order motion is perceived before an accurate representation of luminance is available. These findings are consistent with current accounts of the flash-lag effect. Two control experiments ruled out that the results were due to a general forward tendency. Localization of the target when an auditory signal was presented did not produce forward displacement, and the judged onset of motion was not shifted in the direction of motion.     

Attention maintains mental extrapolation of target position: irrelevant distractors eliminate forward displacement after implied motion

Observers' judgments of the final position of a moving target are typically shifted in the direction of implied motion ("representational momentum"). The role of attention is unclear: visual attention may be necessary to maintain or halt target displacement. When attention was captured by irrelevant distractors presented during the retention interval, forward displacement after implied target motion disappeared, suggesting that attention may be necessary to maintain mental extrapolation of target motion. In a further corroborative experiment, the deployment of attention was measured after a sequence of implied motion, and faster responses were observed to stimuli appearing in the direction of motion. Thus, attention may guide the mental extrapolation of target motion. Additionally, eye movements were measured during stimulus presentation and retention interval. The results showed that forward displacement with implied motion does not depend on eye movements. Differences between implied and smooth motion are discussed with respect to recent neurophysiological findings.     

Autobiographical memory specificity and affect regulation: an experimental approach

This study investigated J. M. G. Williams's (1996) affect-regulation hypothesis that level of specificity of autobiographical memory (AM) is used to minimize negative affect. It was found that a negative event leads to more reports of subjective stress in high- as compared with low-specific participants. Also, afterward, high-specific participants rated their unprompted memories for the event as more unpleasant. The results indicate that, relative to high specificity, being less specific in the retrieval of AMs is associated with less affective impact of a negative event. Results are discussed within the affect-regulation model. It is suggested that future research take a more functional perspective on AM specificity.     

Stem Complexity and Inflectional Encoding in Language Production

Three experiments are reported that examined whether stem complexity plays a role in inflecting polymorphemic words in language production. Experiment 1 showed that preparation effects for words with polymorphemic stems are larger when they are produced among words with constant inflectional structures compared to words with variable inflectional structures and simple stems. This replicates earlier findings for words with monomorphemic stems (Janssen et al., 2002). Experiments 2 and 3 showed that when inflectional structure is held constant, the preparation effects are equally large with simple and compound stems, and with compound and complex adjectival stems. These results indicate that inflectional encoding is blind to the complexity of the stem, which suggests that specific inflectional rather than generic morphological frames guide the generation of inflected forms in speaking words.

Accuracy of head orientation perception in triadic situations: experiment in a virtual environment

Research has revealed high accuracy in the perception of gaze in dyadic (sender- receiver) situations. Triadic situations differ from these in that an observer has to report where a sender is looking, not relative to himself. This is more difficult owing to the less favourable position of the observer. The effect of the position of the observer on the accuracy of the identification of the sender's looking direction is relatively unexplored. Here, we investigate this, focusing exclusively on head orientation. We used a virtual environment to ensure good stimulus control. We found a mean angular error close to 5 degrees. A higher observer viewpoint results in more accurate identification. Similarly, a viewpoint with a smaller angle to the sender's midsagittal plane leads to an improvement in identification performance. Also, we found an effect of underestimation of the error in horizontal direction, similar to findings for dyadic situations.     

Verbal, behavioural and physiological assessment of the generalization of exposure-based fear reduction in a spider-anxious population

Clinical fear of spiders was assessed in 39 patients before and after exposure treatment and at a 3-month follow-up. The assessment included behavioral, physiological and self-report measures. Some patients were tested in the treatment context (group Same), while others were tested in a different context (group Different). Both groups demonstrated a significant fear reduction from pre- to post-treatment in all measures, which persisted at the 3-month follow-up. Contrary to our expectations, no clear difference was observed between the groups at any moment. However, a 1-year follow-up test of the self-report measure revealed a return of fear in group Same, but not in group Different. These results show (1) that the effects of exposure treatment persisted over contexts and time in the short term, and (2) that conducting treatment and tests in different contexts enhanced efficiency of exposure treatment in the long term.     

Test-Taker Reactions to the Selection Process: Effects of Outcome Favorability, Explanations, and Voice on Fairness Perceptions

This study examined the effects of providing an explanation and voice on fairness perceptions and reactions of test takers under favorable and unfavorable selection decisions. Participants took either a cognitive ability test or an overt integrity test in a simulated selection situation. Then, the voice manipulation was introduced. Participants were informed of the hiring decision with or without an explanation. Results showed that type of test had effects on procedural fairness perceptions such that these reactions were more positive when a cognitive ability test was used. The results of voice and explanation manipulations on fairness perceptions indicated that providing an explanation had a positive effect on perceptions but, surprisingly, face-validity perceptions were less favorable when participants had voice opportunity.
