Assesses the influence of rehearsal on recognition reaction times for items from target lists of a length exceeding the span of immediate memory. Also determines what effect, if any, the length of the target list has on recognition latencies that involve only retrieval from inactive memory. (Author/RK)

These experiments attempt to optimize the possibility of demonstrating blocking in a taste-aversion paradigm and to elucidate the conditions under which this interference occurs. (Author/RK)

To complement investigations of the direct effects of lithium toxicosis on consummatory behavior, these experiments were designed to determine the aftereffects on drinking of exposure to a conditioned stimulus previously paired with lithium. (Author/RK)

In four different experiments, brief illumination of a localized visual stimulus was followed by grain presentation unless the pigeon approached the light. Results indicate that although response-reinforcer relations do play a role, stimulus-reinforcer contingencies are the dominant factor in establishing and maintaining approaches to the…

Three experiments were performed to determine if the use of an organizational strategy influenced free-recall performance more than did the degree of semantic elaboration. (Editor)

According to Barlett (1932) remembering prose is a constructive process. Meaningful material is stored in memory in schematic form and recall is achieved by a process of reconstruction. Bartlett observed that recall becomes distorted with the passage of time. This research deals with constructive remembering over time in terms that are compatible…

These experiments show two things: (a) In visual memory, long-term interference on a current item from items previously stored only seems to occur when the current item's retention interval is relatively long, and (b) the visual code appears to decay rapidly, reaching asymptote within 3 seconds of input in the presence of an interpolated task.…

Rates of overt rehearsal and eye movement were compared to each other, and were also compared as predictors of immediate and delayed recall. Concludes that total looking time was the best predictor of long-term retention and that recall performance following overt rehearsal was different from recall performance following silent study.

Examines the effects of different-intensity unconditioned stimuli as well as generalization to related and unrelated test words. Its results indicate that semantic generalization is not a consequence of mediated generalization as traditionally conceived. (Editor/RK)

Three experiments were conducted in an attempt to develop an account of information loss based on the relationships among events occurring at input, during a retention interval, and at output. (Editor)

Two experiments examined the effect of concurrently holding 0, 2, 4, or 6 nouns in memory on the recognition of visual stimuli briefly presented to the left or right visual fields. (Editor)

A familiarity effect in these experiments is defined as a subject's ability to respond more rapidly to a familiar stimulus than to an unfamiliar stimulus. Evidence indicates that familiarity does not affect an initial encoding process, but it can affect a comparison process. (Editor/RK)

A phonetic confusion model and some procedural artifacts were eliminated as sources for individual differences in fusion rate. Results of these two experiments were consistent with the hypothesis that individual differences in fusion rate are due to differences in perceptual dependence on linguistic rules. (Editor/RK)

A multiple regression analysis of sequential effects in magnitude estimation and absolute identification is presented as an alternative to the approach used by Lockhead and his students. The new analysis indicates that sequential effects do not extend over more than one trial. (Editor)

Three experiments were performed to test the assertion that attractiveness of novel or complex stimuli has confounded experiments on the relative importance of S+ and S- in discrete-trial discrimination. (Editor)
