Abstract: Almost everyone would agree that the course of forgetting is some curvilinear function of time. The purpose of the research described herein was to identify the nature of that function. Three experiments are reported, two involving human subjects and one involving pigeons. The human experiments investigated this issue using recall of words and recognition of faces, whereas the pigeon experiment employed the standard delayed matching-to-sample task. In all cases, the course of forgetting was best described by a simple power function of time relative to five other reasonable alternatives (linear, exponential, exponential-power, hyperbolic, and logarithmic). Furthermore, a reanalysis of Ebbinghaus's (1885) classic savings function showed that it, too, declines as a power function of time. These findings suggest that the form of forgetting is a relatively robust property of memory performance and that its mathematical description, perhaps only coincidentally, matches that of the psychophysical function.

Power-law forgetting in synapses with metaplasticity
Anita Mehta,Jean-Marc Luck +1 more
TL;DR: Two models of a metaplastic synapse based on general principles of power-law forgetting with the same universal exponent are devised and investigated, both of which incorporate the separate storage of long- and short-term memories via an array of hidden states.

TL;DR: Data indicate that the primacy and recency effects are related to different neural, and likely cognitive, operations that are dependant on the strategy for information maintenance.

Bias effects in the possible/impossible object decision test with matching objects.
TL;DR: The present study applied the matched-objects design to the original Schacter and Cooper stimuli—same possible objects and matching impossible figures—with minimal procedural variation to show that negative priming for impossible objects derived from the structural properties of these objects, not from the influence of episodic memory on task performance.
Forgetting of Foreign-Language Skills: A Corpus-Based Analysis of Online Tutoring Software.
TL;DR: Improved predictive accuracy of the forgetting model is obtained by augmenting it with features that encode characteristics of a student's initial study of the lesson and the activities the student engaged in between the initial and delayed tests.

Design and evaluation of a cognitive approach for disseminating semantic knowledge and content in opportunistic networks
TL;DR: This work presents a set of algorithms for knowledge and data dissemination in opportunistic networks, based on simple and very effective models (called cognitive heuristics) coming from cognitive sciences, and shows how to exploit them to disseminate both semantic data and the corresponding data items.

TL;DR: In this book van Fraassen develops an alternative to scientific realism by constructing and evaluating three mutually reinforcing theories.

On the law of effect
TL;DR: Experiments on single, multiple, and concurrent schedules of reinforcement find various correlations between the rate of responding and the rate or magnitude of reinforcement, which can be accounted for by a coherent system of equations.
