学前儿童的“心理理论”在不同ToM任务中的发展特点

考察了72名3～5岁儿童在三个改造过的经典错误信念任务中的表现,结果显示,大部分4岁儿童能够正确认识自我错误信念;大部分5岁儿童能够正确认识他人错误信念;大部分3～4岁儿童的自我错误信念认识显著好于他人（真人和玩偶）错误信念认识,5岁时这两种认识才没有显著差异;学前儿童对真人与玩偶错误信念的认识没有显著差异;学前儿童对“意外地点”任务和“意外内容”任务中错误信念问题回答的一致性较高,而对“外表—真实”任务的回答与前两种任务的一致性较低。     

Using cumulative-recall curves to assess the extent of relational and item-specific processing

Although distinguishing between item-specific and relational information has proved to be a useful approach for understanding a variety of important memory phenomena, finding measurement tools for assessing the amount and type of information processed has proven difficult. Using the repeated-testing procedure, Burns (1993) demonstrated that item gains (the recall of items on a later test that were not recalled on earlier tests) and item losses (the forgetting of items on a later test that were recalled on earlier tests) reflected differences in amount of item-specific and relational information processed, respectively. Although several researchers have begun to use the measures with apparent success, the present research demonstrates that the accuracy of the item-gain measure is largely dependent on the rather arbitrary choice of recall-test length. We also show that a related but alternative measure, analysis of cumulative-recall curves, avoids some of the shortcomings of the item gain and loss measures. Moreover, we provide evidence for the generality of the cumulative-recall approach by demonstrating its effectiveness in mixed-list designs.     

Memories defining the self in Alzheimer’s disease

ABSTRACT

There is a debate over the extent to which personal identity or the self is preserved in patients with Alzheimer’s disease (AD). Autobiographical memory deficits at early stages of AD could contribute to altering patients’ self. However, the nature of the relationship between autobiographical memory deficits and the self in AD has not been much investigated experimentally. In the present study, we aimed to investigate the integrative meaning of self-defining memories (SDMs) in early stages of AD and to analyse its relationship with the self-concept. The results showed that, when compared to the control group, AD patients less frequently extracted meaning from their SDMs and the meaning was less frequently tied to the self. Patients exhibited some altered aspects of the self-concept (i.e., complexity and strength), though some other components still persisted (i.e., valence and certainty). Correlation analyses showed that the impaired integrative meaning in the AD group was correlated with some changes in self-concept. We suggest that integrative meaning may act as a bridge between autobiographical memories and the self-concept, with reduced integration abilities appearing as a potential mechanism for the deterioration of the self-concept in AD.     

Investigating the mediating role of self-construal on the relationship between cultural group (Malay and Australian) and the characteristics and functional use of autobiographical memory

ABSTRACT

Cultural differences in autobiographical memory characteristics and function have often been presumed to be associated with different cultural beliefs related to the self. The current research aimed to investigate whether self-construal mediated the relationship between cultural group and the characteristics and functional use of autobiographical memory. Caucasian Australians (n?=?71) and Malay Malaysians (n?=?50) completed an online questionnaire that included the Self-Defining Memory task, the Thinking About Life Experiences Revised Questionnaire and the Self Construal Scale. As expected, the Australian group provided longer, more autonomously oriented, specific memories than the Malay group. However, contrary to our predictions, self-construal did not mediate the relationships between cultural group and memory characteristics. The Malay group reported more frequently using autobiographical memories for self-continuity than the Australian group. Finally, there was support for an indirect pathway between cultural group and use of autobiographical memories for self-continuity and social-bonding through self-construal (i.e. independent self relative to interdependent self). The findings highlight the importance of explicitly examining values assumed to be associated with autobiographical remembering, and relating these values to memory characteristics and function.     

Living in History in Lebanon: The influence of chronic social upheaval on the organisation of autobiographical memories

The Living in History (LiH) effect is a litmus test for the degree to which historical events reorganise autobiographical memory. The LiH effect was studied in two Lebanese samples: a Beiruti sample that lived in the epicentre of the 15-year Lebanese Civil War (1975–1990) and another group from the Bi'qa region who lived in an area that was indirectly exposed for most of the civil war but experienced one short-term period of war during the Israeli invasion. Using the two-phase word-cueing task to elicit dated autobiographical memories, we observed a significantly stronger LiH effect in the Beirut sample but also a significant yet weaker LiH effect in the Bi'qa sample. In addition to the main finding we offer evidence that the LiH effect waxes and wanes with the level of conflict in an area and that reported personal experiences of war exposure predict the strength of the LiH effect. Our findings suggest that collective transitional events which produce a marked change in the fabric of daily living engender historically defined autobiographical periods which give structure and organisation to how individuals remember their past.     

Age-related differences in episodic feeling-of-knowing arise from differences in memory performance

Previous studies about the effects of ageing on the episodic feeling-of-knowing (FOK) accuracy and its underlying processes have yielded conflicting results. Recent work suggests that using alternative measures to gamma correlations might allow more accurate and informative interpretations of metamemory performance in ageing. We therefore investigated this issue with a large sample of 59 young and 61 older participants using alternative signal-detection theory (SDT) measures. These measures (receiver operating characteristic curves and Brier score) are recommended in the literature and able to reveal the characteristic profile of impairment in ageing. Our results suggest that the FOK accuracy deficit observed in the literature arises from differences in memory performance. This observation provides a convenient explanation to the previous discrepancies and furthermore supports the interest of the use of SDT-derived measures in the frame of metamemory.     

Revisiting the rise and fall of false recall: Presentation rate effects depend on retention interval

Leading theories of false memory predict that veridical and false recall of lists of semantically associated words can be dissociated by varying the presentation speed during study. Specifically, as presentation rate increases from milliseconds to seconds, veridical recall is predicted to increase monotonically while false recall is predicted to show a rapid rise and then a slow decrease—a pattern shown by McDermott and Watson (2001) in a study using immediate recall tests. In three experiments we tested the generality of the effects of rapid presentation rates on veridical and false memory. In Experiments 1 and 2 participants exhibited high levels of false recall on a delayed recall test, even for very fast stimulus onset asynchronies (SOA)—contrary to predictions from leading theories of false memory. When we switched to an immediate recall test in Experiment 3 we replicated the pattern predicted by the theories and observed by McDermott and Watson. Follow-up analyses further showed that the relative output position of false recalls is not affected by presentation rate, contrary to predictions from fuzzy trace theory. Implications for theories of false memory, including activation monitoring theory and fuzzy trace theory, are discussed.     

No Justice Without Democracy: A Deliberative Approach to the Global Distribution of Wealth

Abstract

The debate about global distributive justice is characterized by an often stark opposition between universalistic approaches, advocating an egalitarian global redistribution of wealth (Beitz, Pogge, Barry, Tan), and particularistic positions, aiming to justify a restriction of redistribution to the domestic community (D. Miller, R. Miller, Blake, Nagel, Rawls). I argue that an approach starting from the deliberative model of democracy (Habermas) can overcome this opposition. On the one hand, the increasingly global scope of economic interactions implies that the range of individuals concerned with the redistribution of wealth should also be increasingly universal. On the other hand, the need for democratic deliberation refers to the fact that demands of justice should be contextual and should take into account the particular circumstances, needs and values of the people concerned. Both concerns can be realized simultaneously only within a multi‐layered democratic system in which redistribution is a concern at the domestic, the international and the global level.
