Previously rewarding experiences can influence choices in new situations. Past work has demonstrated that existing reward associations can either help or hinder future behaviors and that there is substantial individual variability in the transfer of value across contexts. Developmental changes in reward sensitivity may also modulate the impact of…

Between 6 and 9 years of age, children's free associations shift from syntagmatic to paradigmatic relationships. "Syntagmatic relations" are words that are syntactically adjacent, thematically related ("summer-vacation"), or both; "paradigmatic relations" are words from the same grammatical class, taxonomic category…

Representations of social categories help us make sense of the social world, supporting predictions and explanations about groups and individuals. In an experiment with 156 participants, we explore whether children and adults are able to understand category-property associations (such as the association between "girls" and "liking…

Purpose: The present study examined patterns of demographic characteristics that are predictive of people's automatic preference for people without disabilities over people with disabilities. Method: Predictions of automatic preference for people without disabilities were investigated among 41,789 individuals who volunteered to complete the…

The concept of spreading activation describes how retrieval of one memory cues retrieval of other memories that are associated with it. This study explored spreading activation in 6-, 12-, and 18-month-old infants. Infants (n = 144) learned two tasks within the same experimental session; one task, deferred imitation (DI), is typically remembered…

Although aging causes relatively minor impairment in recognition memory for components, older adults' ability to remember associations between components is typically significantly compromised, relative to that of younger adults. This pattern could be associated with older adults' relatively intact familiarity, which helps preserve component…

The effects of aging and IQ on performance were examined in 4 memory tasks: item recognition, associative recognition, cued recall, and free recall. For item and associative recognition, accuracy and the response time (RT) distributions for correct and error responses were explained by Ratcliff's (1978) diffusion model at the level of individual…

Purpose: The purpose was to determine the number of semantic neighbors, namely, "semantic set size," for 88 nonobjects (J. F. Kroll & M. C. Potter, 1984) and determine how semantic set size related to other measures and age. Method: Data were collected from 82 adults and 92 preschool children in a discrete association task. The nonobjects were…

We investigated children's ability to generate associations and how automaticity of associative activation unfolds developmentally. Children generated associative responses using a single associate paradigm (Experiment 1) or a Deese/Roediger-McDermott (DRM)-like multiple associates paradigm (Experiment 2). The results indicated that children's…

The role of categorical versus associative relations in 5-, 7-, and 11-year-old children's true and false memories was examined using the Deese--Roediger--McDermott (DRM) paradigm and categorized lists of pictures or words with or without category labels as primes. For true items, recall increased with age and categorized lists were better…

Free recall performance of children in grades three, five, seven, and nine and of adults was assessed according to a list of categorically related words. Results indicated that seventh and ninth graders were more apt to use associative relations to begin category clusters than were younger children or adults. (Author/BE)

Two experiments attempted to resolve previous contradictory findings concerning developmental trends in false memories within the Deese-Roediger-McDermott (DRM) paradigm by using an improved methodology--constructing age-appropriate associative lists. The research also extended the DRM paradigm to preschoolers. Experiment 1 (N = 320) included…

Attempts to isolate lexical access latencies by measuring word-naming times in two conditions: (1) words were preidentified and had only to be pronounced on signal; (2) words had to be both identified and pronounced. Results strengthen the conclusion that vocal programing is exempt from the age declines seen in other sensory-motor tracts.…

The present study was designed to explore age differences in the association of temperatures with specific colors, using as stimuli actual felt temperatures rather than the 'imagined' or ambient temperatures used in other studies. (Author)
