Extending the e-z reader model of eye movement control to chinese readers

Chinese readers' eye movements were simulated in the context of the E-Z Reader model, which was developed to account for the eye movements of readers of English. Despite obvious differences between English and Chinese, the model did a fairly good job of simulating the eye movements of Chinese readers. The successful simulation suggests that the control of eye movements in reading Chinese is similar to that in an alphabetic language such as English.     

The illusion of knowledge: When more information reduces accuracy and increases confidence

Intuition suggests that having more information can increase prediction accuracy of uncertain outcomes. In four experiments, we show that more knowledge can decrease accuracy and simultaneously increase prediction confidence. Participants were asked to predict basketball games sampled from a National Basketball Association season. All participants were provided with statistics (win record, halftime score), while half were additionally given the team names. Knowledge of names increased the confidence of basketball fans consistent with their belief that this knowledge improved their predictions. Contrary to this belief, it decreased the participants’ accuracy by reducing their reliance on statistical cues. One of the factors contributing to this underweighting of statistical cues was a bias to bet on more familiar teams against the statistical odds. Finally, in a real betting experiment, fans earned less money if they knew the team names while persisting in their belief that this knowledge improved their predictions.     

Depressogenic inferential styles, negative events, and depressive symptoms in youth: an attempt to reconcile past inconsistent findings

Research examining the diathesis-stress component of the hopelessness theory (HT) in youth has provided mixed support for the theory. One explanation for inconsistent findings is the failure to consider relationships among the three inferential styles posited to serve as vulnerability factors by the theory. The weakest link hypothesis posits that an individual is as vulnerable to depression as his/her most depressogenic inferential style (DIS) makes him/her. A second explanation is that researchers have operationalized "high stress" from a nomothetic, as opposed to an idiographic, perspective. The current study tested the diathesis-stress component of the HT in 230 third-grade and 152 seventh-grade schoolchildren using both a weakest link and an idiographic approach towards analysis. Children completed measures assessing depressive symptoms and DISs. Children subsequently completed measures assessing depressive symptoms and negative events once a week for 6 weeks. Hierarchical linear modeling and time-lagged analyses indicated that a depressogenic weakest link was associated with greater elevations in depressive symptoms following elevations in stress.     

Probability as a psychological distance: Construal and preferences

We argue that probability, like space and time, instantiates psychological distance. Unlikely outcomes may seem more remote than likely outcomes and may therefore be construed at a relatively high level. Specifically, when the probability of an outcome is low, ends-related primary features should be more salient than means-related secondary features, but as the probability of the outcome increases, means-related features may become no less and even more salient than ends-related features. Thus, increases in probability should increase the weight of means-related features relative to the weight of ends-related features in decisions, thereby decreasing (or even reversing) the preference for a more desirable/less feasible outcome over a less desirable/more feasible outcome. We observed this pattern in two experiments. Analyses of judgments, monetary decisions, and self-reported reasons for decisions showed that the weight of means-related features was more sensitive to changes in probability than the weight of ends-related features in decisions.     

Creative innovation or crazy irrelevance? The contribution of group norms and social identity to creative behavior

This paper develops an analysis of innovative behavior and creativity that is informed by the social identity perspective. Two studies manipulated group norms and analyzed their impact on creative behavior. The results of Study 1 show that when people are asked to make a creative product collectively they display conformity to ingroup norms, but that they deviate from ingroup norms when group members make the same products on their own. A parallel result was found in group members’ private perceptions of what they consider creative. In Study 2, the social identity of participants was made salient. Results showed conformity to group norms even when group members worked on their own creations. Findings suggest that innovative behavior is informed by normative context, and that in contexts in which people operate as members of a group (either physically through collective action, or psychologically through social identity salience) innovation will respect normative boundaries.     

The socioecological model of procommunity action: the benefits of residential stability

The authors conducted 3 studies to test a socioecological model of procommunity action. Study 1 showed that residents of stable communities purchased a "critical habitat" license plate to support preservation of the environment in their home state more often than did residents of mobile communities. Study 2 demonstrated that home game baseball attendance was less dependent on the team's record in stable cities than in mobile cities. Study 3, an experiment, showed that residential stability had a causal impact on procommunity behavior. Moreover, the effect of stability was partially mediated by identification with the "community." Together, these studies indicate that residential stability can lead to stronger identification with one's community, which, in turn, leads to more procommunity behaviors.     

An Egalitarian Plateau? Challenging the Importance of Ronald Dworkin’s Abstract Egalitarian Rights

Ronald Dworkin’s work on the topic of equality over the past twenty-five years or so has been enormously influential, generating a great deal of debate about equality both as a practical aim and as a theoretical ideal. The present article attempts to assess the importance of one particular aspect of this work. Dworkin claims that the acceptance of abstract egalitarian rights to equal concern and respect can be thought to provide a kind of plateau in political argument, accommodating as it does a number of well-known ethical theories of social arrangement from utilitarianism to libertarianism. The article explores the moral foundations of these egalitarian rights and critically examines five specific reasons for supposing they matter in political debate. It is argued that though these reasons are perhaps less constructive than they might be reasonably expected to be, there is another more fundamental question we can ask about the scope of egalitarian rights the answer to which might ultimately help to explain their fundamental nature and importance. That question is: equality among whom?     

The impact of visual flow stimulation on anxiety, dizziness, and body sway in individuals with and without fear of heights

Individuals with acrophobia experience anxiety and dizziness when exposed to heights. It may be that their balance system is disturbed and that they therefore have to rely more strongly on visual information.We tested this hypothesis by exposing 20 individuals with high fear of heights and 20 healthy control participants to nine different visual flow stimuli through a head mounted display, thereby inducing a conflict between visual input and somatosensory information. Anxiety and dizziness were assessed repeatedly by means of self-reports, while resultant body sway was measured continuously with a force plate individuals stood on.Individuals with fear of heights felt more anxious and dizzier, and also showed stronger body sway than healthy control participants.Merely receiving visual balance information contradictory to somatosensory balance information is sufficient to induce anxiety, dizziness, and body sway in individuals with fear of heights. An underlying balance dysfunction may contribute to the development of height phobia.     

Are we on a learning curve or a treadmill? The benefits of participative group goal setting become apparent as tasks become increasingly challenging over time

A large body of research has pointed to the utility of individual and group goal setting as a performance enhancement strategy. However, group goal setting is more complex than individual goal setting as the group context often strengthens the desire for voice and the possibility of resistance. In line with this idea, we test the prediction that goal‐related performance improvements should be more marked where groups participate in goal setting rather than having goals imposed—particularly as they become increasingly hard to achieve. These ideas are tested in two experiments (N_groups = 27, 72). Both confirm the capacity for group goal setting to enhance brainstorming performance. More importantly, both studies also show that the benefits of participative goals relative to imposed goals becomes more marked as goals become more difficult over time. In line with social identity and self‐categorization principles, we suggest that this is because increases in participatively set goals appear to provide opportunities for collective self‐actualization and self‐enhancement while increases in imposed goals do not.
