Aims at providing data for evaluating the proposition that associations between exteroceptive (outside) stimuli and illness play a role in determining the effect of unconditioned stimulus preexposure on subsequent taste aversion conditioning. (Author/RK)

Discusses four experiments concerned with environmental determiners of the taste familiarity effect. Specifically, external environmental stimulation experienced by the subject at the time of taste preexposure and taste conditioning was varied in order to assess its influence on taste aversion learning.

Two sets of measurements evaluated performance on typographically inverted text that students had learned to read 13 to 15 months earlier. (Editor)

In three experiments the location of pigeons was monitored during 20-second illuminations of a right or left key presented in various temporal relationships with food delivery. In general, subjects approached a signal positively correlated with food and withdrew from a signal negatively correlated with food. (Editor)

Subjects responded to pairs of test items from learned linear orderings (e.g., Tom is taller than Dick; Dick is taller than Sam, etc.). Results are compared with previous studies of ordered linguistic, perceptual, and numerical information. (Editor/RK)

A model was proposed as an alternative to current models for categorical perception, which refers to the apparent responding to stimuli only in absolute terms. The model proposed that a single (common) factor causes both a peak in the discrimination function and a categorical dichotomy and thus the correlation between the two. (Editor/RK)

Three experiments are reported that were designed to delineate the properties of the stimulus encoding stage in reaction time tasks of varying stimulus-response compatibility. (Editor)

Two experiments examined factors underlying false alarms on recognition tests when the elements of the test items were presented alone for study at different points in time, and when the elements were parts of different 2-element units during study. (Editor)

Three experiments studied the effect of amount and type of concurrent memory load on the rate of readout from iconic memory. (Editor)

When asked to report the first digit that comes to mind, a predominant number (28.4 percent) of the respondents choose 7. Three further experiments sought to establish whether this predominance is due to an automatic activation process or to a deliberate choice. (Editor)

The main finding of these four experiments was that the strong conditioning produced by a brief exposure to a truly random control weakened with prolonged exposure. (Author/RK)

Attempts to evaluate the hypothesis that rats are more hesitant to ingest novel-flavored substances while they are under the influence of a toxic agent than in the normal state. (Author/RK)

Two experiments were conducted in order to investigate the relationship between memory for individual sentences and memory for the holisitic ideas conveyed by those sentences. (Editor)

Three experiments evaluated the effect of poststimulus distractor characteristics in altering recognition of random shapes. (Editor)

Three experiments are reported investigating whether the decreasing recall over trials in the Brown-Peterson paradigm--proactive inhibition (PI)--derives from encoding or storage (availability) differences between items or from retrieval (accessibility) differences. (Editor)
