Updating information in working memory (WM) is a critical executive function responsible both for continuously replacing outdated information with new relevant data and to suppress or inhibit content that is no longer relevant according to task demands. The goal of the present research is twofold: First, we aimed to study updating development in…

Advantageous decision making progressively develops into early adulthood, most specifically in complex and motivationally salient decision situations in which direct feedback on gains and losses is provided (Figner & Weber, 2011). However, the factors that underlie this developmental improvement in decision making are still not well understood.…

Reviews the literature on the relation between early memory development and corresponding changes in brain development of infants. Finds that an adult-like form of explicit memory emerges between 8 and 12 months of age, drawing heavily on limbic and cortical structures. Offers theoretical perspectives for studying the ontogeny of memory. (JW)

Eight-week-old infants learned to execute an operant footkick to produce crib mobile movement in one of two conditions: training duration on (1) varied within single session and (2) consistent across multiple sessions. Results, in contrast with data from 3-month-olds, demonstrated that conditions of original learning influence immediate and…

Overt rehearsal and free recall performance was analyzed longitudinally in two experimental testing sessions at 7 and later at 9 years of age. Measures of short- and long-term memory recall, and two measures of input processing were obtained. Significant increases between age levels were exhibited by all variables except short-term memory.…

Young, middle-aged, and older adults practiced a squaring algorithm. Working-memory and calculation errors were counted. Practice reduced the number of both types of errors; eliminated initial age-related calculation error differences; and slightly reduced initial age-related working-memory error differences. (BC)
