Cognitive and social influences on gang involvement among delinquents in three Chinese cities

Inasmuch as research has held the increase in youth gang activities responsi ble for the escalating level of crime and delinquency in Chinese societies, ascertaining risk or protective factors of gang involvement among Chinese youths is crucial. The factors include those associated with social control, social learning, and cognitive development. To investigate these factors across different sociocultural contexts, we surveyed delinquents in three diverse Chinese cities-Hong Kong, Guangzhou, and Shanghai. Because of the sociocultural differences among the three cities, social control by parents and cognitive development are likely to be greater protective factors in terms of youths' gang involvement in Hong Kong, while social control by teachers is likely to be a greater protective factor in mainland cities. Results bear out these hypotheses.     

Think, blink or sleep on it? The impact of modes of thought on complex decision making

This paper examines controversial claims about the merit of "unconscious thought" for making complex decisions. In four experiments, participants were presented with complex decisions and were asked to choose the best option immediately, after a period of conscious deliberation, or after a period of distraction (said to encourage "unconscious thought processes"). In all experiments the majority of participants chose the option predicted by their own subjective attribute weighting scores, regardless of the mode of thought employed. There was little evidence for the superiority of choices made "unconsciously", but some evidence that conscious deliberation can lead to better choices. The final experiment suggested that the task is best conceptualized as one involving "online judgement" rather than one in which decisions are made after periods of deliberation or distraction. The results suggest that we should be cautious in accepting the advice to "stop thinking" about complex decisions.     

Does response interference contribute to face composite effects?

Holistic processing of faces can be measured as a failure of selective attention to one face-half under instructions to ignore the other face-half in a naming or same/different matching task. But is interference from the irrelevant half due to response interference rather than to holistic processing? Here, participants learned to name two faces “Fred” and two “Bob.” At test, composites were created from top and bottom halves of different learned faces or of a novel face, and composites were either aligned or misaligned. Naming was slower when the irrelevant half was from a different face as opposed to the same face, regardless of whether it was associated with the same name, a different name, or no name, suggesting holistic processing. Interference was eliminated when composite halves were misaligned. These results suggest that, unlike Stroop effects, composite effects are not due to response interference.     

Simple use of BIC to Assess Model Selection Uncertainty: An Illustration using Mediation and Moderation Models

Abstract

The Bayesian information criterion (BIC) has been used sometimes in SEM, even adopting a frequentist approach. Using simple mediation and moderation models as examples, we form posterior probability distribution via using BIC, which we call the BIC posterior, to assess model selection uncertainty of a finite number of models. This is simple but rarely used. The posterior probability distribution can be used to form a credibility set of models and to incorporate prior probabilities for model comparisons and selections. This was validated by a large scale simulation and results showed that the approximation via the BIC posterior is very good except when both the sample sizes and magnitude of parameters are small. We applied the BIC posterior to a real data set, and it has the advantages of flexibility in incorporating prior, addressing overfitting problems, and giving a full picture of posterior distribution to assess model selection uncertainty.     

The application of correspondence analysis to multiple-criteria decision making

The aim of this paper is to show how correspondence analysis can be a useful aid in multiple-criteria decision making, particularly in the case of categorical criteria values. Under different types of input information, the technique is used to perform some preliminary analyses with a bonus of providing a simultaneous graphical representation of the alternatives and criteria. This picture can provide a better understanding of the structure of the two sets of variables to the decision maker before a decision is made.     

Decomposing the construct of ambivalence over emotional expression in a Chinese cultural context

The present study examined the construct of ambivalence over emotional expression proposed by King and Emmons ( 1990 ) in the Chinese context, and identified a factor structure different from those proposed in previous Western studies. The results of this study provided discriminant validity for this newly extracted two-factor structure of ambivalence, viz., Emotional Rumination and Emotional Suppression. Emotional Rumination was significantly predicted by the personality scales of introversion and inferiority, and the belief dimension of fate control, whereas Emotional Suppression was predicted by the personality scales of diversity, face, and harmony, and the belief dimension of social complexity. The different effects of Emotional Rumination and Emotional Suppression in predicting life satisfaction showed that emotional experience has its own specific characteristics in Chinese culture, and that responding to its emic characteristics will yield a more culturally responsive understanding of emotional experience and expression.

Cultural effect on perspective taking in Chinese-English bilinguals

Some recent evidence has suggested that perspective taking skills in everyday life situations may differ across cultural groups. In the present study, we investigated this effect via culture priming in a group of Chinese-English bilingual adults in the context of a communication game. Results showed that the participants made more perspective taking errors when interpreting the game instruction under the Western than the Chinese primes. The findings suggest that the ability to assume others' mental states not only can be used strategically but is also influenced by the currently active cultural frame in the mind of the bilingual. The present study provides the first evidence for a cultural effect on perspective taking using a within-sample approach via culture priming.     

Inhibitory control differentiates rare target search performance in children

Age-related differences in rare-target search are primarily explained by the speed-accuracy trade-off, primed responses, or decision making. The goal was to examine how motor inhibition influences visual search. Children pressed a key when a rare target was detected. On no-target trials, children withheld reactions. Response time (RT), hits, misses, correct rejection, and false alarms were measured. Tapping tests assessed motor control. Older children tapped faster, were more sensitive to rare targets (higher d'), and reacted more slowly than younger ones. Girls outperformed boys in search sensitivity but not in RT. Motor speed was closely associated with hit rate and RT. Results suggest that development of inhibitory control plays a key role in visual detection. The potential implications for cognitive-motor development and individual differences are discussed.     

The impact of rumination on internal attention switching

The present study explored the nature of attention control problems associated with ruminative traits. Experiment 1 aimed to establish the validity of a modified mental counting task that assesses individuals' ability to switch attention between internal mental representations. Reaction time and brain activity (event related potential; ERP) measures were examined, and results showed that the task was sensitive to internal attention switching effects. Experiment 2 assessed how the relationship between ruminative tendencies and switching performance differs when participants attend to neutral versus affective materials under different mood states. Although reaction-time analysis suggested that both mood condition and stimulus affectivity were not significant in altering this association, ERP analysis suggested otherwise. A significant task type×trait rumination × mood condition effect was found for switch-related ERP responses, whereby high ruminators were found to deploy more neuronal resources when switching affective materials in sad mood state.     

Language and age effects in children's processing of word order

We compare the processing of transitive sentences in young learners of a strict word order language (English) and two languages that allow noun omissions and many variant word orders: Turkish, a case-marked language, and Mandarin Chinese, a non case-marked language. Children aged 1–3 years listened to simple transitive sentences in the typical word order of their language, paired with two visual scenes, only one of which matched the sentence. Multiple measures of comprehension (percent of looking to match, latency to look to match, number of switches of attention) revealed a general pattern of early sensitivity to word order, coupled with language and age effects in children's processing efficiency. In particular, English learners showed temporally speedier processing of transitive sentences than Turkish learners, who also displayed more uncertainty about the matching scene. Mandarin learners behaved like Turkish learners in showing slower processing of sentences, and all language groups displayed faster processing by older than younger children. These results demonstrate that sentence processing is sensitive to crosslinguistic features beginning early in language development.
