Psychophysical scaling and strength of nervous system in teenagers

Journal/Book: Psikhol Zh. 1997; 18: 39 Dimitrova Ul., 113095 Moscow, Russia. Mezhdunarodnaya Kniga. 106.

Abstract: Individual differences in strength of the nervous system, subjective judgments on tone loudness (40-120 dB), auditory and vibrating sensitivities were studied in 15 yrs children. Two modes of scaling were used: (1) Stevens method of direct numerical estimation using averaged standard tone 30 dB scored as 10: (2) estimation in terms of emotions (irrelevant, pleasant, unpleasant, painful, intolerable). Strength of the nervous system was assessed by means of slope of dependence between reaction time and tone intensity (SofRT). The correlation between subjective judgment characteristics and strength of the nervous system was found: reduced estimates of low intensity tones, augmented estimates of high intensity tones as well as more pronounced SofRT in Ss with strong nervous system in comparison with Ss with weak nervous system, The correlation of absolute auditory and vibrating thresholds with SofRT was insignificant.
