4～5岁儿童对社会事件记忆的消极偏向

消极偏向是指相对于积极或中性的刺激,消极刺激能够获得更多的注意和认知加工。本研究采用故事法通过三个实验考察4~5岁儿童对社会事件的记忆是否存在消极偏向。实验一发现幼儿对威胁行为的回忆成绩显著优于对中性行为和助人行为的回忆成绩。实验二发现幼儿对悲伤事件的回忆成绩显著优于对中性和愉快事件的回忆成绩。实验三发现幼儿对威胁行为的前瞻记忆成绩显著优于中性和助人行为的前瞻记忆成绩。研究说明无论事件是威胁性的还是非威胁性的,无论是回溯记忆还是前瞻记忆,4~5岁儿童的记忆都表现出消极偏向。     

Memory for "mean" over "nice": the influence of threat on children's face memory

Adults remember faces of threatening over non-threatening individuals. This memory advantage could be indicative of a system rooted deeply in cognitive evolution to track and remember individuals who have been harmful in the past and therefore might be harmful again. Conversely, adults may have learned through experience that it pays to be vigilant. In the present research, we investigated whether attention to threatening individuals is privileged in young children's face memory. In Experiment 1, preschool-age children showed a face recognition memory advantage for individuals who were said to have committed harmful rather than helpful actions. In a further experiment, children did not selectively remember individuals who were described as the recipients of these actions, suggesting that the memory enhancement was produced by threat rather than negative valence. Together, these findings provide evidence for an early-developing system for remembering threatening individuals, consistent with an evolutionary account of its origins.     

When do children trust the expert? Benevolence information influences children's trust more than expertise

How do children use informant niceness, meanness, and expertise when choosing between informant claims and crediting informants with knowledge? In Experiment 1, preschoolers met two experts providing conflicting claims for which only one had relevant expertise. Five‐year‐olds endorsed the relevant expert's claim and credited him with knowledge more often than 3‐year‐olds. In Experiment 2, niceness/meanness information was added. Although children most strongly preferred the nice relevant expert, the children often chose the nice irrelevant expert when the relevant one was mean. In Experiment 3, a mean expert was paired with a nice non‐expert. Although this nice informant had no expertise, preschoolers continued to endorse his claims and credit him with knowledge. Also noteworthy, children in all three experiments seemed to struggle more to choose the relevant expert's claim than to credit him with knowledge. Together, these experiments demonstrate that niceness/meanness information can powerfully influence how children evaluate informants.     

Memory for details about people: familiarity,relatedness, and gender congruency

This study examines factors that influence memory for details about people. In two experiments, subjects learned fictitious details about familiar (friends, relatives) and/or unfamiliar individuals, and were tested both immediately and after a 1-week delay. To control for a confounding between familiarity and genetic relatedness in Experiment 1, in Experiment 2 specific relationships (identical twin, first cousin, acquaintance) were assigned to unfamiliar individuals. Across experiments, retention was enhanced for familiar compared to unfamiliar individuals, for friends/acquaintances compared to relatives, for more closely than distantly related individuals, and for individuals of the opposite gender as the subject.     

Is saccade-induced retrieval enhancement a potential means of improving eyewitness evidence?

Saccade-induced retrieval enhancement (SIRE) is the effect whereby making bilateral saccades enhances the subsequent retrieval of memories. Two experiments explored SIRE's potential to improve eyewitness evidence. Participants viewed slideshows depicting crimes, and received contradictory and additive misinformation about event details either once (Experiment 1) or three times (Experiment 2). Participants then performed saccades or a fixation control task before being tested on their memory for the slideshows and making confidence judgements. Saccades increased discrimination between seen and unseen event details regardless of whether or what type of misinformation was presented. Because prior studies indicated that SIRE might be more robust for individuals who are strongly right-handed versus not, we examined SIRE as a function of handedness and found that saccades improved memory for event details regardless of participants' handedness. However, participants who were not strongly right-handed had fewer false memories than participants who were strongly right-handed, extending previous findings of superior memory among individuals who are not strongly right-handed. Saccades also increased confidence in true memories (Experiment 1) and decreased confidence in false memories (Experiment 2). The results support SIRE's potential to improve eyewitness evidence.     

The effect of social engagement on 24-month-olds' imitation from live and televised models

To date, developmental research has rarely addressed the notion that imitation serves an interpersonal, socially based function. The present research thus examined the role of social engagement on 24-month-olds' imitation by manipulating the social availability of the model. In Experiment 1, the children were more likely to imitate the exact actions of a live socially responsive model compared to a videotaped model who could not provide socially contingent feedback. In Experiment 2, the children were more likely to imitate the exact actions of a model with whom they could communicate via a closed-circuit TV system than a videotaped model who could not provide interactive feedback. This research provides clear evidence that children's imitative behavior is affected by the social nature of the model. These findings are discussed in relation to theories on imitation and the video deficit.     

Motivated social memory: Belonging needs moderate the own-group bias in face recognition

The current research examines why people have superior recognition memory for own-group members compared to other-group members. In two studies, we provide evidence for one motivational mechanism underlying own-group bias—social belonging needs. In Study 1, participants assigned to a minimal group had superior memory for own-group compared to other-group faces, replicating previous research on the own-group bias. This pattern was moderated by participants' need to belong: participants who reported a higher (versus lower) need to belong showed greater own-group memory bias. In Study 2, participants who were socially excluded had superior memory for own-university compared to other-university faces than participants who were selected to work alone by a computer. Together, these studies suggest that chronic belonging needs and social exclusion motivate own-group bias. (124 words)     

Attributions for the negative historical actions of a group

Two field studies examined the attributions made for the historically negative behaviour of a group as a whole, depending on whether the actions were committed by the ingroup or an outgroup. In the first study, Jewish people assigned more internal responsibility to Germans for their treatment of Jewish people during the Second World War than Germans assigned to their own group. In the second study, people attributed the negative historical actions of another nation more internally (and less externally) than similar negative historical actions committed by their own nation. This pattern of intergroup attributional bias was more pronounced among people who highly identified with their national ingroup. Outgroup homogeneity and perceptions of differences between the groups were also significantly predicted by ingroup identification. Links between social identity theory and the intergroup attribution bias are considered. Copyright © 2002 John Wiley & Sons, Ltd.     

The effect of regulation goals on emotional event-specific knowledge

The constructivist nature of autobiographical memory leaves its retrieval susceptible to biases based on the current context. The present study addressed the hypothesis that the same memory could be recalled differently depending on a person's current regulation goals. In Experiment 1, a total of 58 participants recalled three events at a baseline session and again 2 weeks later when expecting to meet with an emotional individual. Individuals expecting to meet with a happy individual decreased the negative—and more specifically sad—words they used compared to the baseline session, whereas those expecting to meet with a sad individual showed the reverse effect. These findings were constrained by individual differences in extraversion. Significant effects were confined to events recalled second in order, suggesting the changes in emotional details might be due to controlled, regulatory processes. Using a false memory list-learning paradigm, Experiment 2 ruled out an alternative interpretation of the findings and confirmed that individuals can bias their memory in accord with regulation goals.     

We Knew It All Along: Hindsight Bias in Groups

Two studies investigated the occurrence of hindsight distortion in groups as compared to individuals. Competing predictions were derived from four theoretical positions: Memory impairment, response bias, self-presentation, and group polarization. In Experiment 1, small groups vs individuals made hypothetical predictions with or without outcome information. Both individuals and groups were found to distort their predictions in the direction of the alleged outcome. Experiment 2 employed a memory design in which individuals vs groups made a series of predictions for which they subsequently received outcome information which was either above or below their prediction or for which they received no outcome information. Subjects had to recall their initial prediction. Results indicated that (a) hindsight bias was slightly attenuated in groups compared to individuals, (b) groups were more likely to recall their original predictions correctly than individuals, (c) this recall advantage of groups disappeared when time taken to make the initial prediction was held constant, and (d) outcome information affected hindsight bias but not hit rates. Results were interpreted as supporting the response bias perspective.     

Observer age and the social transmission of attractiveness in humans: Younger women are more influenced by the choices of popular others than older women

Being paired with an attractive partner increases perceptual judgements of attractiveness in humans. We tested experimentally for prestige bias, whereby individuals follow the choices of prestigious others. Women rated the attractiveness of photographs of target males which were paired with either popular or less popular model female partners. We found that pairing a photo of a man with a woman presented as his partner positively influenced the attractiveness of the man when the woman was presented as more popular (Experiment 1). Further, this effect was stronger in younger participants compared to older participants (Experiment 1). Reversing the target and model such that women were asked to rate women paired with popular and less popular men revealed no effect of model popularity and this effect was unrelated to participant age (Experiment 2). An additional experiment confirmed that participant age and not stimulus age primarily influenced the tendency to follow others' preferences in Experiment 1 (Experiment 3). We also confirmed that our manipulations of popularity lead to variation in rated prestige (Experiment 4). These results suggest a sophisticated model‐based bias in social learning whereby individuals are most influenced by the choices of those who have high popularity/prestige. Furthermore, older individuals moderate their use of such social information and so this form of social learning appears strongest in younger women.     

Working memory and inhibitory control across the life span: Intrusion errors in the Reading Span Test

The aim of this study was to examine to what extent inhibitory control and working memory capacity are related across the life span. Intrusion errors committed by children and younger and older adults were investigated in two versions of the Reading Span Test. In Experiment 1, a mixed Reading Span Test with items of various list lengths was administered. Older adults and children recalled fewer correct words and produced more intrusions than did young adults. Also, age-related differences were found in the type of intrusions committed. In Experiment 2, an adaptive Reading Span Test was administered, in which the list length of items was adapted to each individual’s working memory capacity. Age groups differed neither on correct recall nor on the rate of intrusions, but they differed on the type of intrusions. Altogether, these findings indicate that the availability of attentional resources influences the efficiency of inhibition across the life span.     

Reaping what they sow: Benefits of remembering together in intimate couples

Recent research suggests that remembering with a long-term partner may scaffold successful memory. To test whether collaboration reduces the episodic deficit shown by older adults, we created a social version of Addis, Musicaro, Pan, and Schacter's (2010) episodic memory paradigm. As predicted, in Experiment 1 20 long-married, older adult couples generated more “internal” – on topic, episodic – details when they remembered together versus alone, but the same amount of “external” – off-topic, semantic – details. In Experiment 2 this memory benefit did not extend to 20 young adult couples who generated high levels of internal details together or alone. Notably, however, young adults’ self-reported relationship intimacy was related to their episodic recall across conditions. We discuss these findings in terms of possible benefits of collaboration in the face of ageing and cognitive decline as well as the development over time of “transactive memory systems” in intimate relationships.     

Individuation training with other‐race faces reduces preschoolers’ implicit racial bias: a link between perceptual and social representation of faces in children

The present study examined whether perceptual individuation training with other‐race faces could reduce preschool children's implicit racial bias. We used an ‘angry = outgroup’ paradigm to measure Chinese children's implicit racial bias against African individuals before and after training. In Experiment 1, children between 4 and 6 years were presented with angry or happy racially ambiguous faces that were morphed between Chinese and African faces. Initially, Chinese children demonstrated implicit racial bias: they categorized happy racially ambiguous faces as own‐race (Chinese) and angry racially ambiguous faces as other‐race (African). Then, the children participated in a training session where they learned to individuate African faces. Children's implicit racial bias was significantly reduced after training relative to that before training. Experiment 2 used the same procedure as Experiment 1, except that Chinese children were trained with own‐race Chinese faces. These children did not display a significant reduction in implicit racial bias. Our results demonstrate that early implicit racial bias can be reduced by presenting children with other‐race face individuation training, and support a linkage between perceptual and social representations of face information in children.     

Context and companion's behavior as determinants of cooperation and competition in school-age children

Information about the social context and a companion's actions were studied as determinants of cooperation and competition in middle childhood. In Experiment 1, first-, third-, and fifth-grade children were told that they would play a board game with another same-age, same-sex child (actually a bogus companion). The experimenter's instructions established shared rewards or winner-take-all as outcome conditions. Preprogrammed responses—100% cooperative or 100% competitive—provided information about the companion's actions. Results revealed that the companion's responses alone determined cooperation and competition among the first graders. Third graders used both types of information. Fifth graders, however, demonstrated a bias to respond cooperatively whenever a cooperative cue was present. In Experiment 2, first-grade subjects were given extra rehearsal of the game strategies, a scorekeeping procedure for use during the game, or a combination of the two. Results indicated that, under these conditions, younger subjects were able to use the instructions about reward distribution as well as the companion's actions in guiding their social behavior.     

何以应对道德自我威胁?道德记忆偏差的视角

人们会做出一些不道德的事情,这可能对他们积极的道德自我概念构成威胁。为了应对这种道德自我威胁,人们会表现出道德记忆偏差,即遗忘威胁道德自我的不道德事件或信息。近年来,研究者基于自传体记忆范式、游戏范式、代入范式和自我参照范式,为道德记忆偏差现象提供了证据支持。研究还进一步表明,这种道德记忆偏差可能出于应对道德自我威胁的需要,即人们希望通过有选择地遗忘来维护积极的道德自我概念。 值得注意的是,道德记忆偏差现象存在一些不一致的发现。未来研究应该寻求可能的调节变量,以整合现有不一致的发现,揭示人们使用道德记忆偏差应对道德自我威胁的情境或个体差异。此外,根据道德自我威胁的解释,道德记忆偏差的存在可能需要一定条件。人们做出有意不道德行为时,应该能够意识到自身行为有违道德标准、体验到道德自我威胁,进而表现出道德记忆偏差;但是人们在做出无意不道德行为时,可能不会体验到道德自我威胁,也就不会表现出道德记忆偏差。人们做出不太严重的不道德行为时,道德记忆偏差能够帮助人们很好地应对道德自我威胁。但是人们在做出严重违反道德的行为时,道德记忆偏差可能不足以应对道德自我威胁,该偏差可能就不复存在。 道德记忆偏差与其他应对道德自我威胁策略之间可能存在一定的联系。一种可能性是,道德记忆偏差与这些策略之间是相关补充、共同发挥作用的。还有一种可能性是,其他策略可能为道德记忆偏差的出现提供了条件。人们在做出不道德行为后,可能会通过道德推脱和自我合理化等方式来降低其道德标准,改观其对该事件的评价,从而更容易地模糊不道德行为,表现出道德记忆偏差。除应对道德自我威胁外,道德记忆偏差还存在其他可能的解释。道德记忆偏差可能源自人们的印象管理动机,即人们可能为了维护在他人面前的道德形象而表现出道德记忆偏差。道德记忆偏差还可能发生在记忆加工的不同阶段,比如该现象可能发生在编码阶段,即人们对道德事件的编码加工多于不道德事件;储存阶段,即人们可能受到积极自我图式的影响而对不道德事件产生遗忘;也可能在提取阶段,即人们可能会主动地抑制对不道德事件的提取。未来研究应关注道德记忆偏差存在条件,并在研究广度上扩展其研究范畴,在研究深度上揭示其认知机制,并探究与其他应对道德自我威胁策略的关系。     

自闭症谱系障碍儿童对面孔加工的同龄偏向效应

采用视觉追踪技术,探讨自闭症谱系障碍(autism spectrum disorders, ASD)儿童面孔加工的同龄偏向效应。实验1选取19名ASD儿童和23名生理年龄匹配的普通儿童(typically developing, TD)为被试,通过自由观看同龄和异龄中性面孔,探讨ASD儿童是否存在面孔加工的同龄偏向效应;实验2选取22名ASD儿童和生理年龄匹配的25名TD儿童,通过自由观看快乐、愤怒和恐惧面孔,探讨情绪对ASD儿童面孔加工同龄偏向的影响。结果发现,(1)ASD儿童对同龄中性面孔的注视时间显著大于异龄中性面孔;(2)ASD儿童在愤怒和恐惧情绪下对同龄面孔的注视时间显著大于异龄面孔,而在快乐情绪下同龄和异龄的注视时间则无显著差异。这表明ASD儿童对面孔的注视加工存在同龄偏向效应,且受情绪的影响。     

Language-specific Knowledge and Short-term Memory in Bilingual and Non-bilingual Children

The sensitivity of children's phonological short-term memory performance to languagespecific knowledge was investigated in two experiments. In Experiment 1, monolingual English children, English-French bilingual children, and English children who were learning French as a second language were compared on measures of phonological short-term memory and vocabulary in the two languages. The children's short-term memory performance in each language mirrored their familiarity with English and French, with greater vocabulary knowledge being associated with higher levels of recall of both words and nonwords in that language. This finding was replicated in Experiment 2, in which two groups of children with good knowledge of English and French were examined: native bilingual children who had comparable knowledge of the two languages and non-native bilingual children who had a greater knowledge of their native than second language. The findings indicate that phonological short-term memory is not a language-independent system but, rather, functions in a highly language-specific way.     

Phenomenal characteristics of memories of daily actions in checking‐prone individuals

The purpose of this study was to investigate memories of daily actions in checking‐prone participants. A sample of 419 non‐clinical participants completed a questionnaire evaluating Obsessive–Compulsive Disorder (OCD) and a questionnaire evaluating sensory details, emotions, vividness, confidence and memory perspective of seven everyday actions such as ‘brushing one's teeth’. The main results indicated that checking was related to low levels of visual, kinaesthetic and spatial details in memories for actions, more negative emotions and anxiety when performing actions and low confidence in memory quality. In addition, checking‐prone individuals more frequently reported their memories from the perspective of an external observer than non‐checking‐prone individuals. In general, these results seem to indicate that checking is associated with impersonal memories for everyday actions, as well as low confidence in these memories. The role of anxiety is also evoked, as it was significantly related to poor memory characteristics. Copyright © 2007 John Wiley & Sons, Ltd.
