It's all good: Children's personality attributions after repeated success and failure in peer and computer interactions

The present study examined children's use of behavioural outcome information to make personality attributions in social and non‐social contexts. One hundred and twenty‐eight 3‐ to 6‐year‐olds were told about a story actor who engaged in primarily successful or primarily unsuccessful interactions with several different people (social context) or several different computers (non‐social context). Subsequently, children made behavioural predictions and trait attributions about the actor. Findings indicated that participants were more likely to use past information to make behavioural predictions and trait attributions when hearing about primarily successful than primarily unsuccessful interactions, although there were age‐related differences in trait attribution as a function of success and trait type. There was no support for differential use of information across contexts, as participants' predictions and attributions were similar regardless of hearing about interactions with computers or humans. Factors involved in the development of impression formation are discussed.     

Brief daily exposures to Asian females reverses perceptual narrowing for Asian faces in Caucasian infants

Perceptual narrowing in the visual, auditory, and multisensory domains has its developmental origins during infancy. The current study shows that experimentally induced experience can reverse the effects of perceptual narrowing on infants' visual recognition memory of other-race faces. Caucasian 8- to 10-month-olds who could not discriminate between novel and familiarized Asian faces at the beginning of testing were given brief daily experience with Asian female faces in the experimental condition and Caucasian female faces in the control condition. At the end of 3 weeks, only infants who received daily experience with Asian females showed above-chance recognition of novel Asian female and male faces. Furthermore, infants in the experimental condition showed greater efficiency in learning novel Asian females compared with infants in the control condition. Thus, visual experience with a novel stimulus category can reverse the effects of perceptual narrowing during infancy via improved stimulus recognition and encoding.     

货币·金融危机·新自由主义——关于现代化与当代资本主义的访谈

The current global financial crisis is essentially a credit crisis of currencies. The divorce of the U.S. dollar from Gold Specie Standard makes its issuance under the control of the U.S. government and even risk losing control. When the U.S. dollar becomes the world currency,the U.S government would be able to influence and even control the central banks of other countries through issuing U.S. dollars. However,it may also lead to the credit crisis if there is no sufficient wealth to establish a solid found...     

I need to be your only friend: the effect of salesperson network centrality on opportunistic behavior

Transaction cost economics can be used to detect opportunistic behavior by one or more actors within a sales network. Using a sample of firms in the medical industry, where the role of salespeople is important, this study examines network centrality as a determinant of a salesperson’s opportunistic behavior in intrafirm relationships. The results indicate that opportunistic behavior is affected differently depending on a salesperson’s relational and positional centralities. While relational centrality decreases opportunistic behavior by providing motivation to protect one’s reputation, positional centrality negatively moderates the effect of relational centrality on opportunistic behavior. However, with a high relational centrality, a salesperson is less likely to be opportunistic when she or he is low in positional centrality than when her or his positional centrality is high.     

Preference for attractive faces in human infants extends beyond conspecifics

Human infants, just a few days of age, are known to prefer attractive human faces. We examined whether this preference is human-specific. Three- to 4-month-olds preferred attractive over unattractive domestic and wild cat (tiger) faces (Experiments 1 and 3). The preference was not observed when the faces were inverted, suggesting that it did not arise from low-level image differences (Experiments 2 and 3). In addition, the spontaneous preference for attractive tiger faces influenced performance in a recognition memory task involving attractive versus unattractive tiger face pairings (Experiment 4). The findings suggest that infant preference for attractive faces reflects the activity of general processing mechanisms rather than a specific adaptation to mate choice.     

Cultural differences in the development of cognitive shifting: East-West comparison

Prior research has documented that Japanese children's performance on the Dimensional Change Card Sorting (DCCS) task can be influenced by their observation of another person completing the task, which is referred to as social transmission of disinhibition. The current study explored whether Canadian children would also show a social transmission of disinhibition and whether their performance would be comparable to that of Japanese children. In this study, 3- and 4-year-olds in Canada and Japan were given both the standard version and social version of the DCCS. Results indicated that Canadian children displayed the social transmission of disinhibition, but their effects were significantly weaker than those with Japanese children. On the other hand, performance on the standard DCCS was comparable between children in the two countries. We discuss the results in terms of cultural differences in the relationship between self and other.     

Identifying between‐person and within‐person factors to enhance understanding of observed score profiles

This study aims to reparameterize ordinary factors into between‐ and within‐person factor effects and utilize an array of the within‐person factor loadings as a latent profile which encapsulates all score responses of individuals in a population. To illustrate, the Woodcock–Johnson III (WJ‐III) tests of cognitive abilities were analysed and one between‐ and two within‐person factors were identified. The scoring patterns of individuals in the WJ‐III sample were interpreted according to the within‐person factor patterns. Regression analyses were performed to examine how much the within‐person factors accounted for the person scoring patterns and criterion variables. Finally, the importance and applications of the between‐ and within‐person factors are discussed.     

Immediate emotion-enhanced memory dependent on arousal and valence: The role of automatic and controlled processing

The phenomenon that emotional stimuli are better remembered than neutral ones is called emotion-enhanced memory (EEM). Previous studies have shown that both valence and arousal of stimuli contributed to EEM. Kensinger and Corkin (2004) proposed that the EEM dependent on arousal was associated with automatic encoding processes, whereas the EEM dependent on valence was associated with controlled encoding processes. Their experiment with negative words provided some evidence for this associative pattern. However, it is unclear whether the observed association that occurred with negative emotional stimuli could be replicated with positive emotional stimuli. To further examine this issue, two experiments were conducted to investigate the immediate EEM of emotional words in three different attention conditions using a divided attention (DA) paradigm. Results indicated that the immediate EEM dependent on valence was associated with controlled processing, while the immediate EEM dependent on arousal was not always associated with automatic processing. The immediate EEM dependent on arousal for negative stimuli was associated with automatic processing, whereas the immediate EEM dependent on arousal for positive stimuli was associated with controlled processing. Therefore, the immediate EEM dependent on arousal, whether it is associated with automatic or controlled processing, is moderated by the valence of stimuli.
