A Diffusive-Particle Theory of Free Recall

A Diffusive-Particle Theory of Free Recall

Diffusive models of free recall have been recently introduced in the memory literature, but their potential remains largely unexplored. In this paper, a diffusive model of short-term verbal memory is considered, in which the psychological state of the subject is encoded as the instantaneous position of a particle diffusing over a semantic graph. The model is particularly suitable for studying t...

A theory of interpretive clustering in free recall

The existence of a polysemy effect in episodic memory is demonstrated through an analysis of data from the experiments of Lohnas et al. (2015) and Healey and Kahana (2016). Three word-length related features are reported: (1) the average distance between the serial positions of consecutively recalled words is an increasing function of the second word’s length; (2) the recall of words in the ord...

Recall termination in free recall.

Although much is known about the dynamics of memory search in the free recall task, relatively little is known about the factors related to recall termination. Reanalyzing individual trial data from 14 prior studies (1,079 participants in 28,015 trials) and defining termination as occurring when a final response is followed by a long nonresponse interval, we observed that termination probabilit...

Three-dimensional Free Vibration Analysis of a Transversely Isotropic Thermoelastic Diffusive Cylindrical Panel

The present paper is aimed to study an exact analysis of the free vibrations of a simply supported, homogeneous, transversely isotropic, cylindrical panel based on three-dimensional generalized theories of thermoelastic diffusion. After applying the displacement potential functions in the basic governing equations of generalized thermoelastic diffusion, it is noticed that a purely transverse mo...
