Decay of Immediate Memory with Age

Word-length effects in immediate memory: Overwriting trace decay theory.

Memory is worse for items that take longer to pronounce, even when the items are equated for frequency, number of syllables, and number of phonemes. Current explanations of the word-length effect rely on a time-based decay process within the articulatory loop structure in working memory. Using an extension of Nairne's (1990) feature model, we demonstrate that the approximately linear relationsh...

Modeling age-related differences in immediate memory using SIMPLE.

In the SIMPLE model (Scale Invariant Memory and Perceptual Learning), performance on memory tasks is determined by the locations of items in multidimensional space, and better performance is associated with having fewer close neighbors. Unlike most previous simulations with SIMPLE, the ones reported here used measured, rather than assumed, dimensional values. The data to be modeled come from an...

Decay theory of immediate memory: From Brown (1958) to today (2014).

This work takes a historical approach to discussing Brown's (1958) paper, "Some Tests of the Decay Theory of Immediate Memory". This work was and continues to be extremely influential in the field of forgetting over the short term. Its primary importance is in establishing a theoretical basis to consider a process of fundamental importance: memory decay. Brown (1958) established that time-based...

Polynomial Decay to Thermoelastic Plates with Memory

Interaction of sensory experience and age in spatial memory performances

During a critical period of postnatal age sensory experience has a profound effect on maturation of visual cortical wiring. Electrophysiological evidence is indicating a substantial effect of visual deprivation on the visual cortical response properties. In this study we evaluated effect of light deprivation during a limited time of postnatal age on two aspects of spatial (working and reference...
