Rate Deceleration

Previous research on electrodermal conditioning suggests that the conditioned diminution of the unconditioned response (UR) has an associative basis. The aim of this experiment was to test whether this phenomenon also occurs in heart rate (HR) classical conditioning. For this purpose, a differential classical conditioning was performed. The conditioned stimuli (CSs) were geometrical shapes (the CS+ was a square and the CS− was a triangle) displayed on a computer screen and a burst of white noise was used as unconditioned stimulus (US). For analysis of the conditioned response (CR) components, an interval between CS+ and US of 8 seconds was used. After the acquisition phase, participants were tested using trials with the US preceded either by a CS+, a CS−, or a neutral stimulus (a circle). The results showed conditioned diminution of the UR and suggest that the second heart rate deceleration component (D2) is responsible for the occurrence of this phenomenon.

Experimental Group

A classical conditioning experiment, in which an auditory stimulus was paired with a hypoxic stimulus, was carried out on 34 normal subjects assigned to two groups (experimental and control). Each subject took part in one session divided into two phases, acquisition and test. In the acquisition phase, eight hypoxic and eight auditory stimuli were paired in the experimental group and unpaired in the control group. In the test phase, which was identical for the two groups, the hypoxic stimuli were suppressed and three purely auditory stimuli were presented. Significant differences between the two groups in ventilatory response to these auditory stimuli provided evidence for conditioning. In the control group, no significant changes were elicited by the auditory stimuli, whereas a conditioned increase in total cycle duration was observed in the experimental group. The conditioned response closely resembled the first component of the hypoxic response. Analysis of the pattern of the conditioned response, along with postexperimental interviews, strongly suggests that this response was not mediated by volitional factors.

Upcoming Event

A simple classroom demonstration can dramatically illustrate the process of classical conditioning. This demonstration differs from others because it elicits a conditioned response that differs significantly from the unconditioned response. As a result, this demonstration provides an effective introduction to the contemporary notion that the function of classical conditioning is to help an organism prepare itself for an important, upcoming event. The demonstration requires very little preparation and only a few minutes of class time. Data indicated that the procedure produced a conditioned response and that other processes, such as habituation, cannot explain the results.

Classically Conditioned

Classical conditioning is a quintessential learning process; however, maladaptive forms of conditioning sustain many unhealthy behaviors (e.g., addiction). Mindfulness training is theorized to de-automatize conditioned behavior by decoupling stimulus and response. This study assessed the effect of mindfulness training on conditioned behavior during a classical conditioning task. Findings indicated mindfulness training decreased classically conditioned behavior relative to an active control condition, delaying the onset of first conditioned response and decreasing conditioned response frequency. Thus, mindfulness training may be one method of increasing volitional control over maladaptive conditioned behaviors that contribute to the development and maintenance of clinical disorders.
