延迟间隔和提取条件对短时错误记忆的影响

采用短时DRM迫选任务,探讨提取条件和延迟间隔对短时错误记忆的影响,以进一步考察短时错误记忆的产生机制。结果发现,短时错误记忆的产生主要源于提取时对存贮细节通达的缺失。在无有效提取线索的条件下,延迟间隔能够增加错误记忆率;而有效提取线索存在时,真实记忆痕迹的可通达性增加能够极大避免错误记忆的产生,延迟间隔的作用则不显著。该实验的结果是对错误记忆理论解释的一种补充。     

Counterfactual comparison modulates fairness consideration in the mini‐ultimatum game: An event‐related potentials study

Existing literature on the mini‐ultimatum game indicates that counterfactual comparison between chosen and unchosen alternatives is of great importance for individual's fairness consideration. However, it is still unclear how counterfactual comparison influences the electrophysiological responses to unfair chosen offers. In conjunction with event‐related potentials’ (ERPs) technique, the current study aimed to explore the issue by employing a modified version of the mini‐ultimatum game where a fixed set of two alternatives (unfair offer vs. fair alternative, unfair vs. hyperfair alternative, unfair offer vs. hyperunfair alternative) was presented before the chosen offer. The behavioral results showed that participants were more likely to accept unfair chosen offers when the unchosen alternative was hyperunfair than when the unchosen alternative was fair or hyperfair. The ERPs results showed that the feedback‐related negativity (FRN) elicited by unfair chosen offers was insensitive to the type of unchosen alternative when correcting for possible overlap with other components. In contrast, unfair chosen offers elicited larger P300 amplitudes when the unchosen alternative was hyperunfair than when the unchosen alternative was fair or hyperfair. These findings suggest that counterfactual comparison may take effect at later stages of fairness consideration as reflected by the P300.     

Judgments About Fact and Fiction by Children From Religious and Nonreligious Backgrounds

In two studies, 5‐ and 6‐year‐old children were questioned about the status of the protagonist embedded in three different types of stories. In realistic stories that only included ordinary events, all children, irrespective of family background and schooling, claimed that the protagonist was a real person. In religious stories that included ordinarily impossible events brought about by divine intervention, claims about the status of the protagonist varied sharply with exposure to religion. Children who went to church or were enrolled in a parochial school, or both, judged the protagonist in religious stories to be a real person, whereas secular children with no such exposure to religion judged the protagonist in religious stories to be fictional. Children's upbringing was also related to their judgment about the protagonist in fantastical stories that included ordinarily impossible events whether brought about by magic (Study 1) or without reference to magic (Study 2). Secular children were more likely than religious children to judge the protagonist in such fantastical stories to be fictional. The results suggest that exposure to religious ideas has a powerful impact on children's differentiation between reality and fiction, not just for religious stories but also for fantastical stories.     

Ternary eutectic growth during directional solidification of Ag–Cu–Sb alloy

The directional solidification process of ternary Ag_42.4Cu_21.6Sb₃₆ eutectic alloy within a wide growth rate range from 2 to 60 μm/s was accomplished at a constant temperature gradient of 50 K/cm. As growth rate increases, the ternary (θ(Cu₂Sb) + ε(Ag₃Sb) + Sb) eutectic morphology evolves from “lamellar (θ + ε) plus fibrous (Sb)” structure into “(θ + Sb) fibres in continuous ε matrix” structure. The θ and (Sb) phase spacings decrease with the increase of growth rate according to power functions with exponent values of 0.55 and 0.56, respectively. It is also found that the microhardness of directionally solidified Ag_42.4Cu_21.6Sb₃₆ alloy samples is enhanced with the increase of growth rate, and the decrease of θ and (Sb) phase spacings.     

Muslim Experiential Religiousness in Pakistan: Meaning in Life,General Well-Being and gender differences

This study examined relationships of Muslim spirituality with positive psychology in Pakistan. In a sample of 200 university students and community members, the spirituality of Muslim Experiential Religiousness displayed direct linkages with Meaning in Life and General Well-Being subscales. Muslim Experiential Religiousness also correlated positively with single-item assessments of the Intrinsic, Extrinsic Personal, and Extrinsic Social Religious Orientations and explained the relationships of these religious motivations with General Life Satisfaction. Women scored higher than men on Muslim Experiential Religiousness, but at least some linkages of Muslim spirituality with positive psychology were more robust in men. As in other recent investigations, these data confirmed Muslim Experiential Religiousness as a valid index of Muslim spirituality beyond the Iranian cultural context in which it was developed.     

Tracing children's vocabulary development from preschool through the school‐age years: an 8‐year longitudinal study

In this 8‐year longitudinal study, we traced the vocabulary growth of Chinese children, explored potential precursors of vocabulary knowledge, and investigated how vocabulary growth predicted future reading skills. Two hundred and sixty‐four (264) native Chinese children from Beijing were measured on a variety of reading and language tasks over 8 years. Between the ages of 4 to 10 years, they were administered tasks of vocabulary and related cognitive skills. At age 11, comprehensive reading skills, including character recognition, reading fluency, and reading comprehension were examined. Individual differences in vocabulary developmental profiles were estimated using the intercept‐slope cluster method. Vocabulary development was then examined in relation to later reading outcomes. Three subgroups of lexical growth were classified, namely high‐high (with a large initial vocabulary size and a fast growth rate), low‐high (with a small initial vocabulary size and a fast growth rate) and low‐low (with a small initial vocabulary size and a slow growth rate) groups. Low‐high and low‐low groups were distinguishable mostly through phonological skills, morphological skills and other reading‐related cognitive skills. Childhood vocabulary development (using intercept and slope) explained subsequent reading skills. Findings suggest that language‐related and reading‐related cognitive skills differ among groups with different developmental trajectories of vocabulary, and the initial size and growth rate of vocabulary may be two predictors for later reading development.     

The effects of affective and cognitive elaborations from Facebook posts on consumer attitude formation

This research investigates the effects of affect and cognition in consumers' information processing of branded content on Facebook pages. A model was suggested to delve into the elaboration process leading to consumer attitude formation. A 2 (purchase‐decision involvement: low versus high) × 2 (product categories: hedonic versus utilitarian) × 2 (sources of Facebook posts: brand posts versus consumer posts) between‐subjects experiment was conducted online. The validated model demonstrates the main effects that affective elaboration significantly supersedes cognitive elaboration in forming attitudes toward the posts and attitudes toward the brand. Post hoc analyses show further evidence of the interaction effects that affective elaboration is the dominant influencer when consumers process brand‐related information in Facebook posts across situations. Theoretical implications for future research and managerial suggestions for social media marketing are discussed. Copyright © 2015 John Wiley & Sons, Ltd.     

Electrophysiological difference between the representations of causal judgment and associative judgment in semantic memory

Causally related concepts like “virus” and “epidemic” and general associatively related concepts like “ring” and “emerald” are represented and accessed separately. The Evoked Response Potential (ERP) procedure was used to examine the representations of causal judgment and associative judgment in semantic memory. Participants were required to remember a task cue (causal or associative) presented at the beginning of each trial, and assess whether the relationship between subsequently presented words matched the initial task cue. The ERP data showed that an N400 effect (250–450 ms) was more negative for unrelated words than for all related words. Furthermore, the N400 effect elicited by causal relations was more positive than for associative relations in causal cue condition, whereas no significant difference was found in the associative cue condition. The centrally distributed late ERP component (650–750 ms) elicited by the causal cue condition was more positive than for the associative cue condition. These results suggested that the processing of causal judgment and associative judgment in semantic memory recruited different degrees of attentional and executive resources.
