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information in working memory (WM) is a critical executive function responsible both for continuously replacing outdated information with new relevant data and to suppress or inhibit content that is no longer relevant according to task demands.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.…

This research examined the effects of bimodal audiovisual and unimodal visual stimulation on infants' memory for the visual orientation of a moving toy hammer following a 5-min, 2-week, or 1-month retention interval. According to the intersensory redundancy hypothesis (L. E. Bahrick & R. Lickliter, 2000; L. E. Bahrick, R. Lickliter, & R. Flom,…

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)

Two studies with 80 5- and 8-year olds found that initial recognition tests elevated children's false-memory responses on delayed tests, and that false-memory creation exceeded true-memory inoculation in 5- and 8-year olds, producing net loss of accuracy over time. (MDM)

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.…

Two studies examined 6- and 9-year-old children's recall about events in which they had participated one to two years earlier. Found that amount of information reported in free recall decreased over the one- or two-year delays. For 6-year olds, there was a small decrease in accuracy of free recall. Reinstating specific cues maintained recall, but…

Eight-, eleven-, and nineteen-year-olds' memory for spatial locations over an extended time period was assessed. Study suggested that adults remember spatial location information better than children over time because adults code location information in more organized representations and use better retrieval cues. (RWB)

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…

Examined performance of first through sixth graders on conditional-inference task, using causal conditionals and a generation of alternatives task. Found a steady age-related increase in uncertainty responses to two uncertain logical forms and an increase in production of disabling conditions for "modus ponens." Individual differences in inference…

Two experiments examined the effects of a change in a reinforcing stimulus's color on memory for an operant response in three- to four-month-old infants. (Author/RH)

Three experiments examined kindergartners' and second graders' retention in the context of two distinctiveness manipulations, the von Restorff and bizarre imagery paradigms. Results showed that: older children retained more information from lists of pictures or interactive images over 3 weeks than younger; younger children failed to benefit from…

Investigated effects of object reinstatement on event recall by 6- and 9-year olds'. Subjects were interviewed either 10 days and again 10 weeks after an event, or only 10 weeks after an event. Interviewing included free recall, prompts, and questions. Found that age, delay, and object reinstatement all affected amount and accuracy of recall. (JW)

Generic noun phrases ("Birds lay eggs") are important for expressing knowledge about abstract kinds. The authors hypothesized that genericity would be part of gist memory, such that young children would appropriately recall whether sentences were presented as generic or specific. In 4 experiments, preschoolers and college students (N = 280) heard…

Investigated deferred imitation ability for six actions in 14-month-old infants. After a week's delay, infants were tested on their ability to imitate the actions.Those who had been exposed to modeling produced significantly higher instances of the target actions. (SKC)
