Top-down influences make saccades deviate away: the case of endogenous cues

We tested a recent hypothesis suggesting that the eye deviates away from a location when top-down preparation can influence target selection. Participants had to make an eye movement to a peripheral target. Before the upcoming target, a central cue indicated the likely target location. Results show that when the target was presented at a location different from that indicated by the cue, eye movements to the target deviated away from the cued location. Because central cues are under top-down control, the present results are in line with a determining role of top-down preparation on saccade direction. These results contrast with the findings reported in a similar paradigm executed with hand movements, in which the movements were mostly initiated in the direction of the cued location. Therefore, we conclude that inhibitory effects typically observed when executing eye movements may not be observed when executing hand movements in similar conditions.     

Group-level self-definition and self-investment: a hierarchical (multicomponent) model of in-group identification

Recent research shows individuals' identification with in-groups to be psychologically important and socially consequential. However, there is little agreement about how identification should be conceptualized or measured. On the basis of previous work, the authors identified 5 specific components of in-group identification and offered a hierarchical 2-dimensional model within which these components are organized. Studies 1 and 2 used confirmatory factor analysis to validate the proposed model of self-definition (individual self-stereotyping, in-group homogeneity) and self-investment (solidarity, satisfaction, and centrality) dimensions, across 3 different group identities. Studies 3 and 4 demonstrated the construct validity of the 5 components by examining their (concurrent) correlations with established measures of in-group identification. Studies 5-7 demonstrated the predictive and discriminant validity of the 5 components by examining their (prospective) prediction of individuals' orientation to, and emotions about, real intergroup relations. Together, these studies illustrate the conceptual and empirical value of a hierarchical multicomponent model of in-group identification.     

Attention and gaze shifting in dual-task and go/no-go performance with vocal responding

Evidence from go/no-go performance on the Eriksen flanker task with manual responding suggests that individuals gaze at stimuli just as long as needed to identify them (e.g., Sanders, 1998). In contrast, evidence from dual-task performance with vocal responding suggests that gaze shifts occur after response selection (e.g., Roelofs, 2008a). This difference in results may be due to the nature of the task situation (go/no-go vs. dual task) or the response modality (manual vs. vocal). We examined this by having participants vocally respond to congruent and incongruent flanker stimuli and shift gaze to left- or right-pointing arrows. The arrows required a manual response (dual task) or determined whether the vocal response to the flanker stimuli had to be given or not (go/no-go). Vocal response and gaze shift latencies were longer on incongruent than congruent trials in both dual-task and go/no-go performance. The flanker effect was also present in the manual response latencies in dual-task performance. Ex-Gaussian analyses revealed that the flanker effect on the gaze shifts consisted of a shift of the entire latency distribution. These results suggest that gaze shifts occur after response selection in both dual-task and go/no-go performance with vocal responding.     

Timing a week later: The role of long-term memory in temporal preparation

Temporal preparation has been investigated extensively by manipulating the foreperiod, the interval between a warning stimulus and target stimulus requiring a speeded response. Although such research has revealed many effects of both the duration and distribution of foreperiods on reaction times, the underlying cognitive mechanism is still largely unknown. Here, we test a recent proposal that temporal preparation is driven by the retrieval of memory traces of past experiences from long-term memory rather than by knowledge about upcoming events. Two groups of participants received different foreperiod distributions in an acquisition phase, which was followed a week later by a transfer phase, in which both groups received the same distribution of foreperiods. We found that the effects of the different foreperiod distributions presented in the acquisition phase were still apparent a week later during the transfer phase, as the reaction time patterns of both groups reflected the old distributions. This occurred even though both groups were provided with full information about the change in the distribution of foreperiods at the start of the transfer phase. These findings provide compelling evidence that long-term memory plays an important role in temporal preparation.     

The effect of directive tutor guidance on students' conceptual understanding of statistics in problem‐based learning

Background. Education is aimed at students reaching conceptual understanding of the subject matter, because this leads to better performance and application of knowledge. Conceptual understanding depends on coherent and error‐free knowledge structures. The construction of such knowledge structures can only be accomplished through active learning and when new knowledge can be integrated into prior knowledge. Aims. The intervention in this study was directed at both the activation of students as well as the integration of knowledge. Sample. Undergraduate university students from an introductory statistics course, in an authentic problem‐based learning (PBL) environment, were randomly assigned to conditions and measurement time points. Method. In the PBL tutorial meetings, half of the tutors guided the discussions of the students in a traditional way. The other half guided the discussions more actively by asking directive and activating questions. To gauge conceptual understanding, the students answered open‐ended questions asking them to explain and relate important statistical concepts. Results and conclusions. Results of the quantitative analysis show that providing directive tutor guidance improved understanding. Qualitative data of students' misconceptions seem to support this finding. Long‐term retention of the subject matter seemed to be inadequate.     

The Link: An Alternative Educational Program in the Netherlands to Reengage School-Refusing Adolescents With Schooling

Facets of school life affect the development and maintenance of school refusal (SR). These facets will warrant attention during intervention for SR. This paper considers a range of school-related factors associated with SR, grouped according to five domains of school climate. It also describes school-based interventions for SR in the form of alternative educational programs (AEPs). The paper then presents the Link, an AEP for Dutch adolescents with SR. The Link offers an educational setting that addresses school-related factors associated with SR. After participation in the Link, adolescents are helped to return to a more typical educational setting. Based on a review of 30 case files, we provide an account of adolescents who have participated in the Link. Often, these adolescents displayed chronic and severe SR, met criteria for anxiety or depressive disorders, and were diagnosed with an autism spectrum disorder. The Link process is illustrated via a case vignette. Thereafter, the role of AEPs in the treatment of SR is discussed.     

Treatment of acrophobia in virtual reality: the role of immersion and presence

In this study the effects of virtual reality exposure therapy (VRET) were investigated in patients with acrophobia. Feelings of presence in VRET were systematically varied by using either a head-mounted display (HMD) (low presence) or a computer automatic virtual environment (CAVE) (high presence). VRET in general was found to be more effective than no treatment. No differences were found in effectiveness between VRET using an HMD or CAVE. Results were maintained at 6 months follow-up. Results of VRET were comparable with those of exposure in vivo (Cyberpsychology and Behavior 4 (2001) 335). In treatment completers no relationship was found between presence and anxiety. Early drop-outs experienced less acrophobic complaints and psychopathology in general at pre-test. They also experienced less presence and anxiety in the virtual environment used in session one as compared to patients that completed VRET.     

Toward an Integrative Perspective on Distinct Positive Emotions for Political Action: Analyzing,Comparing, Evaluating,and Synthesizing Three Theoretical Perspectives

Which emotions explain why people engage in political action (e.g., voting, protesting)? To answer this question, theory and research in psychology and political science predominantly focused on distinct negative emotions such as anger. The current article conceptually explores the motivational potential of distinct positive emotions by developing an integrative perspective that specifies which positive emotions can be differentiated (i.e., their form), which function these emotions have, and which implications these have for explaining political action. To this end, I analyze, compare, evaluate, and synthesize three approaches to positive emotions (affective intelligence theory, appraisal theories of emotion, and broaden-and-build theory). This perspective generates new hypotheses for the field to test, including the role played by distinct positive emotions such as joy, inspiration, interest, hope, and pride in motivating political action. I discuss how this perspective may help restore a balance in research on emotions and political action by focusing on the motivational potential of distinct positive emotions.     

The evil eye: Eye gaze and competitiveness in social decision making

We demonstrate that a person's eye gaze and his/her competitiveness are closely intertwined in social decision making. In an exploratory examination of this relationship, Study 1 uses field data from a high‐stakes TV game show to demonstrate that the frequency by which contestants gaze at their opponent's eyes predicts their defection in a variant on the prisoner's dilemma. Studies 2 and 3 use experiments to examine the underlying causality and demonstrate that the relationship between gazing and competitive behavior is bi‐directional. In Study 2, fixation on the eyes, compared to the face, increases competitive behavior toward the target in an ultimatum game. In Study 3, we manipulate the framing of a negotiation (cooperative vs. competitive) and use an eye tracker to measure fixation number and time spent fixating on the counterpart's eyes. We find that a competitive negotiation elicits more gazing, which in turn leads to more competitive behavior.
