Constraints on general slowing: a meta-analysis using hierarchical linear models with random coefficients

Article Abstract:

Hierarchical linear models (HLM) with random coefficients are more appropriate than ordinary least squares (OLS) methods in the meta-analyses of response time (RT) data and for testing general slowing theories. HLM show significant variance in slowing across tasks and demonstrate a process-specific effect by showing less slowing for memory scanning than for visual-search and mental-rotation tasks. OLS, on the other hand, does not account for the nested nature of multitask RT data, making them unsuitable for testing GS theories.

Effects of age on contextually mediated associations in paired associate learning

Article Abstract:

An age-mediated associative shortcoming in paired-associate learning especially of an episodic memory task that has pairs of unrelated items is studied. Differences are noticed in correct-recall probabilities and intrusion analysis showing that backward and transitive associations are sensitive to aging.

Why a superman cannot help a tsunami: activation of grammatical class influences resolution of young and older adults' tip-of-the-tongue states

Article Abstract:

A study was carried out to find out the activation of grammatical class influence on young, young-old, and old-old adults' resolution of tip-of-the-tongue states. It was noticed that phonologically related words influenced tip-of-the-tongue resolution.
