Cardiac responses to appetitive stimuli have been studied as indices of motivational states and attentional processes, the former being associated with cardiac acceleration and latter deceleration. Very few studies have examined heart rate changes in appetitive classical conditioning in humans. The current study describes the development and pilot testing of a classical conditioning task to assess cardiac responses to appetitive stimuli and cues that reliably precede them. Data from 18 adults were examined. They were shown initially neutral visual stimuli (putative CS) on a computer screen followed by pictures of high-caloric food (US). Phasic cardiac deceleration to food images was observed, consistent with an orienting response to motivationally significant stimuli. Similar responses were observed to non-appetitive stimuli when they were preceded by the cue associated with the food images, suggesting that attentional processes were engaged by conditioned stimuli. These autonomic changes provide significant information about classical conditioning effects in humans.

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.

Two experiments focused on two information variables relevant to changes in heart rate, field dependence and the ability to perceive one's own heart rate. In Exp. I, 14 field-independent and 17 field-dependent subjects completed a heart-rate perception and a voluntary heart-rate control task. The anticipated superiority in heart-rate control by field-independent subjects was detected although no evidence was found for a relationship between the amount of biofeedback available in the situation and voluntary control of the cardiovascular system. Exp. II involved 9 field-independent and 8 field-dependent subjects in a classical conditioning paradigm involving shock sensitivity. In contrast with Exp. I, in this phase of the study heart-rate increases were correlated with the ability of the subject to discriminate heart beats, especially for the field-independent group. It was concluded that field dependence and heart-rate perception are related to classically conditioned heart-rate increase for some subjects and further that field dependence may be a potent variable operating in those situations involving the voluntary control of heart rate without exteroceptive feedback.
