Both associative activation and thematic extraction count,but thematic false memories are more easily rejected

The main aim of this study was to analyse the roles played by associative activation and thematic extraction in the explanation of false memories using the Deese, Roediger, McDermott (DRM) paradigm. Associative lists with two different types of critical items (CIs) were used: one, the associative CI, corresponded to the word most strongly primed by the associates in the list and another, the thematic CI, was the word that best described the theme of the list. Following three different types of encoding instructions (standard, warning or strategic), false recognition for these two types of CIs was analysed in either self-paced or speeded response recognition tests. The results showed considerable levels of false memories for both types of CIs. Even without the quality of being “good themes”, associative CIs produced high levels of false recognition, which suggests that associative activation plays a prominent role in false memory formation. More interestingly, thematic CIs were more prone to be edited out, reinforcing the argument that thematic identifiability has a major role in the rejection of false memories.     

The relation of the conceptual self to recent and distant autobiographical memories

Based on the self-memory system model (SMS; Conway, Singer, & Tagini, 2004) of autobiographical memory, this study uses a large sample of young and middle-aged adults to investigate the relation between individuals’ current self-characteristics and the content of both their earliest childhood memory and a recent memory. In the first session, participants’ current self-characteristics were assessed. In the second session, individuals provided a written narrative of their earliest childhood memory and a more recent memory (within-participants design) and rated the self themes present in each memory. In keeping with the SMS model, findings show that current self-characteristics were reflected in individuals’ memories. As predicted, however, recent memories were more frequently linked to current self-characteristics than were earliest memories. All six current self-characteristics predicted the inclusion of these themes in recent memories, but only four self-characteristics were associated with memory themes in earliest memories. The relation between current self-characteristics and memory themes did not differ across young and middle-aged adults, suggesting developmental stability in these relations. Findings provide general support for the SMS model but also suggest possibilities for its extension and refinement.     

Relationships Among Education,Age, and Cognitive Functioning in Older African Americans: The Impact of Desegregation

The current study sought to examine whether there were differences in the structure of specific cognitive abilities and their association with age and education in a sample of African American elders with two different early educational experiences. The study was conducted with a sample of 197 community dwelling older adults ranging in age from 50 to 79 years (mean age = 61.50 years, SD = 7.30 years). The sample included 79 individuals who attended a desegregated school at anytime during their formal education, while 118 participants completed their schooling without ever attending a desegregated school. Major results included: (1) typical patterns among cognitive abilities and age as well as years of education were found in the full sample of participants; (2) the pattern of age differences in cognition differed between the two groups. Regarding the latter, the desegregated sample exhibited significant negative age differences for some cognitive abilities, while the segregated group did not. Discussion focuses on the importance of considering the nature of the educational experience when examining cognitive aging in African American elders.     

Influence of general and specific autobiographical recall on subsequent behavior: The case of cognitive performance

Two studies tested the impact of autobiographical recall of general versus specific academic success or failure on actual task performance. As expected, it was found that general memories of failure and specific memories of success resulted in worse performance than general memories of success and specific memories of failure. In Study 1, this performance pattern was obtained on a standard math test. In Study 2, it was replicated on a test of intellectual ability, and a mediation by fear of failure was documented. The present findings offer direct evidence that autobiographical memories of success and failure impact actual performance and also reveal the role of memory specificity in this influence.     

Using story contexts to bias children’s true and false memories

The effects of embedding standard Deese/Roediger-McDermott (DRM) lists into stories whose context biased interpretation either toward or away from the overall themes of the DRM lists on both true and false recognition were investigated with 7- and 11-year-olds. These biased story contexts were compared with the same children’s susceptibility to false memory illusions using the standard DRM list presentation paradigm. The results showed the usual age effects for true and false memories in the standard DRM list paradigm, where 11-year-olds exhibited higher rates of both true and false recognition compared with the 7-year-olds. Importantly, when DRM lists were embedded in stories, these age effects disappeared for true recognition. For false recognition, although developmental differences were attenuated, older children were still more susceptible to false memory illusions than younger children. These findings are discussed in terms of current theories of children’s false memories as well as the role of themes and elaboration in children’s memory development.     

错误记忆的无意识机制初探

研究表明,错误记忆十分顽固,一经产生便难以消退,即使是在严格的有意识控制之下,比如预先警告条件下等。这就引起研究者对错误记忆中无意识机制的探讨。本文以错误记忆的这一顽固性特征为切人点,结合多种形式错误记忆的研究成果,尝试剖析错误记忆发生过程中无意识的作用机制,并对近年来兴起的错误记忆无意识机制的实证研究进行了介绍。     

Growing old: A psychoanalyst’s point of view1

With the help of clinical examples, the author shows that psychoanalysis or psychotherapy after the age of 70 can be a fascinating experience, one that enables patients to reconstruct their internal history in such a way that their final years can be given their rightful place in the overall journey through life. Often it will be a matter of going beyond the conflict between paralysing time with the illusion of keeping death at bay and taking the transient nature of life into account in order to perceive its true flavour. We can grow old passively, juxtaposing different periods of our life without linking them together, thereby creating the illusion of time without end; or we can grow old actively, integrating the different phases of our life into a coherent historical narrative. This representation of time leaves the door open for experiences which the author calls ‘small seconds of eternity’. We can all experience such moments when we are deeply moved – joyfully or painfully – by something, so that we perceive another quality of time that goes beyond its chronological dimension without all the same negating it. Helping elderly people to identify these seconds of eternity and catch hold of them can be an invaluable experience for them. Perhaps we need to see our life unfold through the chronology of its different phases in order to discover, second by second, how to express on an everyday basis something of which we have had an inkling in some second of eternity.     

Enhanced perceptual priming for neutral stimuli occurring in a traumatic context: two experimental investigations

Intrusive memories in posttraumatic stress disorder are often triggered by stimuli that are perceptually similar to those present shortly before or during the trauma. The present study aims to examine the possible role of perceptual priming in this phenomenon. It further investigates whether the degree of perceptual priming is associated with dissociation and whether both perceptual priming and intrusive memories can be reduced through elaboration. Two experiments measured perceptual priming for neutral stimuli that immediately preceded a "traumatic" event. Volunteers (N=46, 92) watched a series of "traumatic" and neutral picture stories, and completed a blurred object identification (perceptual priming) memory task, and a recognition memory task. Participants in Experiment 1 were selected to score either high or low on the Trait Dissociation Questionnaire [Murray, Ehlers, & Mayou (2002). Dissociation and posttraumatic stress disorder: Two prospective studies of motor vehicle accident survivors. British Journal of Psychiatry, 180, 363-368]. They also completed a state dissociation measure in the session. Experiment 2 randomly allocated participants to an experimental condition designed to increase elaboration or to a control condition. This experiment also included a measure of intrusive memories. Both experiments found enhanced perceptual priming for the stimuli that immediately preceded the "traumatic" stories compared to those preceding neutral stories. Participants with high trait dissociation showed relatively stronger perceptual perceptual priming. The degree of perceptual priming for stimuli from the "traumatic" stories also correlated with state dissociation (Experiment 1). Experimental manipulation of the elaboration of the stories showed that elaboration reduced the enhanced perceptual priming effect and the relative probability of reexperiencing symptoms (Experiment 2). The results support the role of perceptual priming in intrusions after traumatic events.
