Predicting which childhood memories persist: contributions of memory characteristics.

This investigation identified memory-level predictors of the survivability of 4- to 13-year-old children's earliest recollections over a 2-year period. Data previously reported by Peterson, Warren, and Short (2011) were coded for inclusion of emotion terms and thematic, chronological, and contextual narrative coherence. In addition, the uniqueness and content of the reported events were classified, and the presence or absence of event reminders was recorded. The use of logistic multilevel modeling indicated that emotion and each dimension of coherence added to the prediction of a memory's survivability over and above age-related variance. In contrast, event uniqueness, content category, reminders, and word count were not associated with retention. The findings help explain why particular early memories endure over time.

Brief report: making experience personal: internal states language in the memory narratives of children with and without Asperger's disorder.

The development of the personal past is complex, requiring the operation of multiple components of cognitive and social functioning. Because many of these components are affected by autism spectrum disorders, it is likely that autobiographical memory in children with Asperger's Disorder (AD) will be impaired. We predicted that the memory narratives of children with AD, in comparison to typically-developing peers, would reflect less personal interpretation as evidenced by internal states language. Thirty children with AD and 20 typically-developing children aged 6-14 reported their earliest memories and two emotional experiences (one positive and one negative). Consistent with our predictions, children with AD included fewer emotional, cognitive, and perceptual terms than the comparison sample.

Fragile but real: children's capacity to use newly acquired words to convey preverbal memories.

There is ongoing debate about children's ability to use subsequently acquired language to describe preverbal experiences. This issue was addressed experimentally in this investigation using a novel paradigm. Two-year-old children who lacked color words were individually taught to activate a bubble machine by selecting a particular color of bubble solution. The children then participated in weekly, experimenter-provided activities that fostered their acquisition of the color labels. After 2 months, their ability to apply the newly acquired words in reporting the original event was assessed. A significant proportion of the children demonstrated verbal recall when prompted in the presence of physical reminders of the event. These findings indicate that some early, preverbal memories are translated into words at a later time.
