The present experiment was a preliminary attempt to use the psychophysical scaling methods of magnitude estimation and cross-modal matching to investigate suprathreshold judgments of lingual vibrotactile and auditory sensation magnitudes for 20 normal young adult subjects. A 250-Hz lingual vibrotactile stimulus and a 1000-Hz binaural auditory stimulus were employed. To obtain judgments for nonoral vibrotactile sensory magnitudes, the thenar eminence of the hand was also employed as a test site for 5 additional subjects. Eight stimulus intensities were presented during all experimental tasks. The results showed that the slopes of the log-log vibrotactile magnitude estimation functions decreased at higher stimulus intensity levels for both test sites. Auditory magnitude estimation functions were relatively constant throughout the stimulus range. Cross-modal matching functions for the two stimuli generally agreed with functions predicted from the magnitude estimation data, except when subjects adjusted vibration on the tongue to match auditory stimulus intensities. The results suggested that the methods of magnitude estimation and cross-modal matching may be useful for studying sensory processing in the speech production system. However, systematic investigation of response biases associated with vibrotactile-auditory psychophysical scaling tasks appears to be a prerequisite.

Abstract The effect of stimulus valence was examined in the evoked cardiac response (ECR) elicited by the exposition of neutral and negative slides as well as by an innocuous auditory stimulus presented on the affective foregrounds generated by the slides. The exposition of the aversive slide produced prolonged cardiac deceleration in comparison with the neutral slide. Similar prolonged deceleration accompanied exposition of the neutral auditory stimulus on the negative visual foreground in comparison with the neutral foreground. We interpret these results as an autonomic correlate of extended stimulus processing associated with the affective stimulus. The initial deceleration response, covering two or three slower heart beats, may be prolonged for several seconds before HR reaches the baseline level again. In such a case the evoked cardiac deceleration can be functionally divided into two parts: the reflexive bradycardia (ECR1) elicited by neutral stimuli and a late decelerative component (LDC). We can speculate that the latter is associated with an additional voluntary continuation of processing of the stimulus. This must involve some cognitive aspect different from the mental task performance which leads to the accelerative ECR2, and we suggest that processing of a stimulus with negative valence is involved in generating the LDC.

Self Reports

The reliability of an attention-focusing technique was assessed for 12 subjects over 4 sessions. Subjects' thought intrusions were counted while they were focusing on either visual or auditory stimuli. Digital temperatures were recorded and an experimental-situation questionnaire was administered. This technique provides extremely reliable self-reports across the sessions. The total number of intrusions was higher for the auditory stimulus than for the visual stimulus. The study's relevance to assessing self-monitoring techniques such as meditation is discussed.

Maternal Glucose

The relationships between arterial plasma insulin, glucose, and fructose concentrations during the fed and fasted state were studied in seven fetal lambs and their mothers. A significant correlation between insulin and glucose concentration was noted in all fetal lambs and in their mothers. Fetal sensitivity to glucose, as measured by the slopes of the insulin-response curves, was equal to that of the adult although the fetal response was shifted to the left of the maternal. Glucose infusion in four fetal lambs caused significant insulin elevations but no early insulin response (phase I). Maternal fasting caused no alteration in glucose-induced response in the fetus. Similar glucose infusions in newborn and 1-mo-old lambs demonstrated significant early-phase insulin secretion. Basal insulin to glucose ratios were consistent with an adult pattern as early as 3 days after birth.
