The relation between neural and perceptual intensity: a comparative study on the neural and psychophysical response to taste stimuli.

1. Recording the summated electrical response from the human chorda tympani in the middle ear provides data for a quantitative study of the relation between the neural activity and the strength of the stimulus applied to the tongue which can be compared with the relation between the subjective estimation and the stimulus strength.2. Full comparative data obtained from two patients showed a very high correlation between the functions describing the subjective and the neural response in relation to the strength of citric acid and sucrose solutions applied to the tongue. In a third patient the same high correlation was obtained for NaCl and citric acid.3. The good agreement between the individual neurophysiological experiments and the psychophysical group experiment favours the view that a fundamental congruity is found between neural activity and perceptual intensity.

Psychophysiological responses to exercise in type A/B men.

Previous research concerning physical exercise has yielded mixed results with regard to the possible influence of the Type A behavior pattern (TABP) on ratings of perceived exertion. However, almost all studies have been performed in the confined space of a laboratory. Few have studied the influence of an individual's behavior pattern outdoors in the field where most everyday exercise takes place. Hence, the present study compared three groups of subjects: one group with pronounced TABP, one showing very little TABP, and finally one intermediate group exhibiting an average level of Type A behavior. The results indicate that there are distinct and statistically significant differences between the groups. Type A individuals underestimate their degree of perceived exertion at comparable levels of heart rate. Thus, an individual's behavior pattern ought to be considered when ratings of perceived exertion are used to quantify exercise intensity.
