Fear of Crime and Behavioral Adaptations: Testing the Effects of Fear of Violence on Unstructured Socializing with Peers

This study examines whether fear of violent crime experienced by adolescents influences their involvement in unstructured socializing with peers. To test this relationship, we examine data on youth in Chicago collected as part of the Project on Human Development in Chicago Neighborhoods (PHDCN). The results show that the fear of violent crime in neighborhoods and at schools reduces participation in unstructured socializing with peers. However, this result was only observed for adolescents living in neighborhoods with low levels of concentrated disadvantage. This study provides insight into the consequences of fear of crime for individual behavior. Fear of crime can result in withdrawal from social situations, including avoidance of situations that increase the risk for delinquency and victimization.     

Iki and Contingency: A Reconstruction of Shūzō Kuki’s Early Aesthetic theory

Iki is the key word of Shūzō Kuki’s The Structure of Iki, and it became one of the most widely recognized Japanese aesthetic categories mainly due to this work. However, in The Problems of Contingency, which is Kuki’s most important philosophical work, there is no discussion of iki again, and consequently, most commentators of Kuki fail to see the correlation between his theories of iki and contingency. This article, by contrast, intends to provide a new interpretation of iki in the light of Kuki’s theory of contingency. The specific thesis of this paper is that aesthetic phenomena categorized as subject to the principles of iki are positively evaluated in Japanese culture just because the consciousness of iki is just one form of the consciousness of contingency, in which the awareness of alternatives to the actual situation could produce considerable spiritual entertainment for aesthetic subjects.     

Hypothesis Testing of the <Emphasis Type="Italic">Q</Emphasis>-matrix

The recent surge of interests in cognitive assessment has led to the development of cognitive diagnosis models. Central to many such models is a specification of the Q-matrix, which relates items to latent attributes that have natural interpretations. In practice, the Q-matrix is usually constructed subjectively by the test designers. This could lead to misspecification, which could result in lack of fit of the underlying statistical model. To test possible misspecification of the Q-matrix, traditional goodness of fit tests, such as the Chi-square test and the likelihood ratio test, may not be applied straightforwardly due to the large number of possible response patterns. To address this problem, this paper proposes a new statistical method to test the goodness fit of the Q-matrix, by constructing test statistics that measure the consistency between a provisional Q-matrix and the observed data for a general family of cognitive diagnosis models. Limiting distributions of the test statistics are derived under the null hypothesis that can be used for obtaining the test p-values. Simulation studies as well as a real data example are presented to demonstrate the usefulness of the proposed method.     

Task-irrelevant emotional faces impair response adjustments in a double-step saccade task

Cognitive control enables us to adjust behaviours according to task demands, and emotion influences the cognitive control. We examined how task-irrelevant emotional stimuli impact the ability to inhibit a prepared response and then programme another appropriate response. In the study, either a single target or two sequential targets appeared after emotional face images (positive, neutral, and negative). Subjects were required to freely viewed the emotional faces and make a saccade quickly upon target onset, but inhibit their initial saccades and redirect gaze to the second target if it appeared. We found that subjects were less successful at inhibiting their initial saccades as the inter-target delay increased. Emotional faces further reduced their inhibition ability with a longer delay, but not with a shorter delay. When subjects failed to inhibit the initial saccade, the longer delay produced longer intersaccadic interval. Especially, positive faces lengthened the intersaccadic interval with a longer delay. These results showed mere presence of emotional stimuli influences gaze redirection by impairing the ability to cancel a prepared saccade and delaying the programming of a corrective saccade. Therefore, we propose that the modulation of response adjustment exerted by emotional faces is related to the stage of initial response programming.     

The Way Evaluation Tastes: Tasting as an Embodied Cue of Evaluation

The current theory and research on embodiment have indicated that the basic bodily experiences, which may be more fundamental and important than previously suggested, can influence human cognitive processes. Drawing upon this perspective, the present study examined the hypothesis that the psychological experience of evaluation is grounded in the physical experience of tasting. In three experiments, we found that a tasting cue facilitated evaluation-related conceptual processing in a lexical decision task (Experiment 1), and induced a desire to evaluate toward novel stimuli (Experiment 2). Furthermore, sweet tastes were associated with more positive and secure evaluations than bitter tastes (Experiment 3). These findings provide converging evidence supporting the prediction that tasting as an embodied cue of evaluation.     

National Culture,Creativity, and Productivity: What’s the Relationship with Student Achievement?

Using Hofstede’s culture dimensions and World Values Survey (WVS) dimensions, the study uses a series of multiple regressions to explore the relationship among national culture, creativity as measured by patents, economic productivity as measured by gross domestic product per capita, and student achievement as measured by Trends in International Mathematics and Science Study. The findings of this exploratory study highlight long-term orientation value from Hofstede’s national culture dimensions and tradition versus secular-rational values from the WVS as the most significant predictors of student academic achievement. A series of 12 regression analyses indicated significant relationships among student achievement, creativity, and economic productivity with models explaining between 19.9% and 76.0% of the variance among countries.     

Association between MTHFR C677T polymorphism and depression: a meta-analysis in the Chinese population

Depression is a worldwide public health issue, and its prevalence increases each year. Although a number of studies have been conducted on the association between MTHFR C677T polymorphism and depression in China, this association remains elusive and controversial. To clarify the impact of MTHFR C677T polymorphism on the risk of depression, a meta-analysis was performed in the Chinese population. Relevant studies were identified using PubMed, Springer Link, Ovid, Chinese Wanfang Data Knowledge Service Platform, Chinese National Knowledge Infrastructure and Chinese Biology Medicine through May 5, 2015. Pooled odds ratios (ORs) and 95% confidence intervals (CIs) were used to assess the strength of the associations. A total of 13 case–control studies including 1895 patients and 1913 controls were involved in this meta-analysis. Overall, T variant of MTHFR C677T gene polymorphism was significantly associated with an increased risk of depression in the Chinese population (T vs. C: OR = 1.52, 95% CI = 1.24–1.85; TT + CT vs. CC: OR = 1.64, 95% CI = 1.16–2.30; TT vs. CC: OR = 2.19, 95% CI = 1.49–3.24; TT vs. CC + CT: OR = 1.80, 95% CI = 1.31–2.46). In subgroup analyses stratified by geographic area and source of controls, the significant results were found in population-based studies, in hospital-based studies, in North and South China. The risk conferred by MTHFR C677T polymorphism is higher in North China than in South China. In conclusion, this meta-analysis suggests that MTHFR C677T polymorphism is associated with depression in the Chinese population, but these associations vary in different geographic locations.     

Consumers' attributions and brand evaluations in product‐harm crises: The role of implicit theories of personality

This study aims to examine the moderating role of implicit theories of personality in the relationship between corporate recovery strategy (i.e., support versus stonewalling) and consumers' attributions (and brand evaluations). It is suggested that consumers' implicit theories about the fixedness/malleability of personality can affect consumers' attributions and brand evaluations during a product‐harm crisis. In addition, corporate image (i.e., strong versus weak) can moderate the influence of the role of implicit theories of personality. Two experiments were conducted to examine the proposed hypotheses. Results of Experiment 1 show that consumers who endorse entity theory (i.e., entity theorists) are likely to attribute crisis as more internal, stable, and controllable, particularly when they do not have any prior knowledge about the firm. The entity theorists would have more negative brand evaluations than incremental theorists (who endorse incremental theory), when “support” strategy was used by the firm. Results of Experiment 2 show that entity theorists are prone to have more external (internal) and unstable (stable) attributions toward a firm with a strong (weak) corporate image. Furthermore, entity theorists would provide more positive brand evaluations than incremental theorists when “stonewalling” strategy was used by a firm with strong corporate image, but not when “support” strategy was used by a firm with weak corporate image. Managerial implications are provided to managers with regard to product‐harm crisis and recovery strategies. Copyright © 2015 John Wiley & Sons, Ltd.     

Dissociable effects of fear and disgust in proactive and reactive inhibition

Numerous studies have demonstrated that negative emotional distracters impair inhibitory control. Nevertheless, two issues have emerged in prior studies. First, fear and disgust were inappropriately treated as a single category, which is particularly concerning given that they have been recently demonstrated to exert different impacts on inhibitory control. Second, inhibitory control might not be a unitary construct, as it can be further divided into proactive and reactive inhibition. Therefore, the present study aimed to investigate whether fearful and disgusting distracters have differential effects on proactive and reactive inhibition. Twenty-four female participants were instructed to perform a modified stop-signal task superimposed on a fearful, disgusting, or neutral image cue. Results showed that fearful distracters improved reactive inhibition when compared to disgusting and neutral distracters, while disgusting distracters enhanced proactive inhibition when compared to fearful distracters. Further, reactive and proactive inhibition was positively correlated under fearful, disgusting, and neutral contexts. This study is the first to provide evidence that fear and disgust may affect proactive and reactive inhibition differently. These results add to a growing literature linking emotion and inhibitory control, and they expand our understanding of the relationship between emotion and inhibition.
