WORKING MEMORY AND VISUAL
EXPECTATIONS IN 3-MONTH-OLD INFANTS (in progress)
|
| Previous infant research has indicated a developmental trend in the formation of expectations for picture sequence more complex than a simple 1-1 (left-right) alternation (Canfield & Haith, 1991). Specifically, 3-month-olds have difficulty with 2-1 (left-left-right) sequences, whereas 5-month-olds, who have no trouble with forming an expectation in a 2-1 sequence, have difficulty with a 3-1 (left-left-left-right) sequence. It has been suggested that this developmental trend in forming an expectation in complex sequences is due to the development of working memory and its capacity. If working memory and expectation formation are related, then mechanisms that facilitate encoding in working memory might be available to support expectation formation. Furthermore, factors that limit the functioning of working memory should similarly limit the formation of expectations. One such limitation is the the temporal decay of information if it is not being used to do some cognitive or behavioral "work." This project is intended to examine whether expectation formation, specifically the formation of expectations for event content (Adler & Haith, 2003), is limited by temporal decay, as would be predicted if expectation formation relies on working memory. |
