The Stories We Keep: Autobiographical Memory in American and Chinese Middle-Aged Adults

JOURNAL OF PERSONALITY, Issue 5 2004
Qi Wang
They each recalled 20 memories from any period of their lives. Memory content was analyzed as a function of culture (U.S. and China), life period (childhood, youth, early midlife, and peak midlife), and gender (female and male). Across the four life periods, Americans provided more memories of individual experiences and unique, one-time events and focused on their own roles and emotions. In contrast, Chinese were more inclined to recall memories of social and historical events and placed a great emphasis on social interactions and significant others in their memory narratives. Chinese also more frequently drew upon past events to convey moral messages than did Americans. In addition, memory content evidenced age-related increases in both autonomous and social orientations. Findings are discussed in light of the self-definitional and directive functions of Autobiographical memory in the context of culture. [source]

What remains of that day: The survival of children's autobiographical memories across time

APPLIED COGNITIVE PSYCHOLOGY, Issue 4 2010
Gwynn Morris
In this study we investigated the contributions of the content and the coherence of initial event reports to the survival of autobiographical memories during part of the lifespan eventually obscured by childhood amnesia. Over 100 children reported personal experiences when they were 4, 6 or 8 years old, enabling a determination of age-related differences in two aspects of narrative coherence: Theme and chronology. Content was assessed separately through the presentation of directed memory probes. After a 1-year delay, younger children more frequently failed to report target experiences. Multilevel modelling indicated that the survivability of a memory was predicted over and above the child's age by high thematic coherence of the initial memory narrative, but not by the memory content. It is possible that memories described in a highly thematically coherent narrative are indicative of well-integrated event memories, and thus likely to be cued more often, resulting in their long-term survival.

Effects of dopamine-related gene,gene interactions on working memory component processes

EUROPEAN JOURNAL OF NEUROSCIENCE, Issue 5 2009
Christine Stelzel
Abstract Dopamine modulates complex cognitive functions like working memory and cognitive control. It is widely accepted that an optimal level of prefrontal dopamine supports working memory performance. In the present study we used a molecular genetic approach to test whether the optimal activity of the dopamine system for different component processes of working memory is additionally related to the availability of dopamine D2 receptors. We sought evidence for this assumption by investigating the interaction effect (epistasis) of variations in two dopaminergic candidate genes: the catechol- O -methyltransferase (COMT) Val158Met polymorphism, which has been shown to influence prefrontal dopamine concentration, and the DRD2/ANKK1-Taq-Ia polymorphism, which has been related to the density of D2 receptors. Our results show that COMT effects on working memory performance are modulated by the DRD2/ANKK1-TAQ-Ia polymorphism and the specific working memory component process under investigation. Val, participants , supposedly characterized by increased prefrontal dopamine concentrations , outperformed Val+ participants in the manipulation of working memory contents, but only when D2 receptor density could be considered to be high. No such effect was present for passive maintenance of working memory contents or for maintenance in the face of distracting information. This beneficial effect of a balance between prefrontal dopamine availability and D2 receptor density reveals the importance of considering epistasis effects and different working memory subprocesses in genetic association studies.
