The purpose of the present study was to examine the relative adequacy of the dry mouth vs. emotional theories of SIP using the desalivate rat. (Author)

Pairing a novel flavor with illness results in the conditioning of aversions to that flavor. This article reported a series of experiments examining the effect of several parameters of prior exposure to the illness on the acquisition of learned taste aversions. (Author/RK)

Does similarity in the location and temporal intensity pattern of the CS and UCS permit more rapid conditioning despite the presence of stimulus pairings in all groups? The following experiments attempt to assess the role of such factors in determining the rate of acquisition of a conditioned emotional response. (Author)

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. (Author/RK)

The experiments reported here describe the relationships between the reflex-modulating effects of compounded stimuli and the effects of these stimuli when they act in isolation. (Author)

While incentive contrast has been reliably demonstrated in single-response situations, tests for contrast-of-choice behavior have invariably failed to obtain the effect. Three experiments were reported that eliminated features of prior methodology which can mask the effect. (Editor/RK)

The present research evaluated the refractorylike response decrement, as found in habituation of auditory evoked peripheral vasoconstriction in rabbits, to determine whether or not it represents a short-term habituation process distinct from effector fatigue or sensory adaptation. (Editor)

Using rats and pigeons as subjects, the effects of varying amounts of reinforcement on the rate and temporal patterns of interim and terminal behaviors engendered by periodic feeding schedules were assessed in three experiments. (Author/KC)

Five experiments investigated the differential effects of shock punishment on nonconsummatory licking (dry licking) and lever pressing. Results support a motivationally based theory of punishment involving the role of incentive stimuli associated with the particular responses studied. (Editor/RK)

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)

Rat received conditioning based upon a food unconditioned stimulus and then received manipulations designed to reduce the value of that food. The effects of these manipulations were assessed during extinction tests of the conditioned stimuli. (Editor/RK)

Three experiments are reported in which rats first received 50 escapable or inescapable signaled-shock trials. The results of the experiments are discussed in terms of a learned active-inactive predisposition to respond. (Editor/RK)

This article demonstrated that equations derived from Herrnstein's matching law can make quantitative predictions for many of the effects David Premack has studied on the relative nature of reinforcement. (Author/RK)

This study provided added support for the generalization that the neural processes associated with the startle reflex are engaged by small changes in the auditory environment. They also pointed to a measure of separation between the processes responsible for inhibition and those responsible for latency shift. (Editor/RK)
