The time course of plausibility effects on eye movements in reading: evidence from noun-noun compounds

Readers' eye movements were monitored as they read sentences containing noun-noun compounds that varied in frequency (e.g., elevator mechanic, mountain lion). The left constituent of the compound was either plausible or implausible as a head noun at the point at which it appeared, whereas the compound as a whole was always plausible. When the head noun analysis of the left constituent was implausible, reading times on this word were inflated, beginning with the first fixation. This finding is consistent with previous demonstrations of very rapid effects of plausibility on eye movements. Compound frequency did not modulate the plausibility effect, and all disruption was resolved by the time readers' eyes moved to the next word. These findings suggest (contra Kennison, 2005) that the parser initially analyzes a singular noun as a head instead of a modifier. In addition, the findings confirm that the very rapid effect of plausibility on eye movements is not due to strategic factors, because in the present experiment, unlike in previous demonstrations, this effect appeared in sentences that were globally plausible.     

Does maintenance of colour categories rely on language? Evidence to the contrary from a case of semantic dementia

Recent neuropsychological evidence, supporting a strong version of Whorfian principles of linguistic relativity, has reinvigorated debate about the role of language in colour categorisation. This paper questions the methodology used in this research and uses a novel approach to examine the unique contribution of language to categorisation behaviour. Results of three investigations are reported. The first required development of objective measures of category coherence and consistency to clarify questions about healthy control performance on the freesorting colour categorisation task used in previous studies. Between-participant consistency was found to be only moderate and the number of colour categories generated was found to vary markedly between individuals. The second study involved longitudinal neuropsychological examination of a patient whose colour categorisation strategy was monitored in the context of a progressive decline in language due to semantic dementia. Performance on measures of category coherence and consistency was found to be relatively stable over time despite a profound decline in the patient's colour language. In a final investigation we demonstrated that, for both the patient and controls, between- and within-participant consistency were higher than expected by (a) random sorting and (b) sorting perceptually similar chips together. These findings indicate that the maintenance of colour categorisation need not depend on language.     

Correlates of premarital relationships among unmarried youth in Pune district, Maharashtra, India

CONTEXT: Although premarital partnerships-whether or not they involve sex-are widely discouraged in India, some youth do form such partnerships. It is important to know more about the nature of and the factors associated with these relationships. METHODS: Data are drawn from a community-based study of 15-24-year-olds in urban slum and rural settings in Pune District, Maharashtra. Multivariate analyses were conducted to identify associations between youths' individual, peer and family factors and their experience of romantic relationships and physical intimacy, including intercourse. RESULTS: Among young men, 17-24% had had a romantic relationship, 20-26% had engaged in some form of physical intimacy and 16-18% had had sex; the proportions among young women were 5-8%, 4-6% and 1-2%, respectively. Exposure to alcohol, drugs or pornographic films and having more frequent interaction with peers were positively associated with romantic and sexual relationships for both young women and young men. Educational attainment was negatively associated with both types of relationships for young women, but only with sexual relationships for young men. Closeness to parents was negatively associated with relationships only for young women. Young women whose father beat their mother were more likely than other young women to form romantic partnerships, and those beaten by their family had an elevated risk of entering romantic and sexual partnerships. Youth who reported strict parental supervision were no less likely than others to enter relationships. CONCLUSIONS: Program interventions should ensure that youth are fully informed and equipped to make safe choices and negotiate wanted outcomes, while positively influencing their peer networks; encourage closer interaction between parents and children; and be tailored to the different circumstances and experiences of young women and men.     

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?
