Four experiments examined the effect of label training on redintegrative memory for novel shapes (remembering the whole shape when only a part is presented). (Editor)

In two experiments, subjects were given five successive short-term memory tests. The findings suggested spatial location as a potential encoding dimension of verbal material. (Editor/RK)

The three experiments reported in this article were concerned with the question of how response factors influence the process of stimulus encoding. (Author)

These experiments suggested that human subjects perceived velocity and acceleration directly and accurately. As well, they suggested that extrapolation of velocity is performed accurately through a direct extension of the movement that was seen. (Author/RK)

Three experiments investigated the relationship in speech perception between the mechanisms that determine the source of speech sounds and those that analyze their actual acoustic contents and extract from them the acoustic cues to a sound's phonetic description. (Author/RK)

Experimenters in the past have reported that when insulin is used as the unconditioned stimulus (US), rats will learn an aversion to a sodium chloride but not a sucrose solution, whereas with formalin as the US, they will learn an aversion to a sucrose but not a saline solution. The present experiments failed to confirm these findings. (Editor)

These experiments investigate the degree to which neophobia, the reluctance to consume novel food, can be modified by toxicosis, the conditions under which the contingency between ingestion and illness enhances neophobia, and the manner in which previously learned aversions mediate subsequent enhanced neophobia. (Author/RK)

These experiments investigate situations in which a negative correlation involves a 24 hour delay between the occurrence of a conditioned stimulus and an unconditioned stimulus; they also investigate the mechanism by which any inhibition so produced might occur. (Author/RK)

This research has three purposes: 1) to determine whether subjects instructed to study silently in a free-recall experiment engage in associative encoding, 2) to test the validity of associative ability as an individual difference variable, 3) to test for an interaction between presentation rate and associative reaction time. (Editor/RK)

From experiments showing that subjects differentially attend to parts of the visual field, psychologists have inferred a limitation on human visual information processing capacity. The model presented describes an optimal way to allocate a limited quantity of "cognitive resources", "attention" or "mental effort". An experiment tests this model.…

Three experiments were performed using a recognition probe procedure to test the subject's recognition of the order of two items from a dichotically presented list. (Editor)

Examines the hypothesis that the identification of a briefly presented visual target is impeded by a patterned mask that immediately precedes and/or follows it. (Author/RK)

Tests the hypothesis that the effectiveness of discriminative stimuli as reinforcers is a function of the magnitude of the difference between them. (Author/RK)

The research reported here was directed at evaluating whether or not the effectiveness of a Pavlovian unconditioned stimulus (US) in promoting associative learning is reduced if the US is shortly preceded by another occurrence of the same US. (Author)

Stimulus analyzer theory as proposed by Sutherland and Mackintosh (1971) makes the unique prediction that the first-experienced reinforcement schedule will influence resistance to extinction more than subsequent schedules. Results presently reported of runaway acquisition and extinction indicate the opposite: C-P consistently produce substantially…
