Perceived Duration

There is converging evidence that the duration of an auditory event can affect the perceived duration of a co-occurring visual event. When a brief visual stimulus is accompanied by a longer auditory stimulus, the perceived visual duration stretches. If this reflects a genuine sustain of visual stimulus perception, it should result in enhanced perception of non-temporal visual stimulus qualities. To test this hypothesis, in a temporal two-alternative forced choice task, 28 participants were asked to indicate whether a short (∼24 ms), peri-threshold, visual stimulus was presented in the first or in the second of two consecutive displays. Each display was accompanied by a sound of equal or longer duration (36, 48, 60, 72, 84, 96, 190 ms) than the visual stimulus. As a control condition, visual stimuli of different durations (matching auditory stimulus durations) were presented alone. We predicted that visual detection can improve as a function of sound duration. Moreover, if the expected cross-modal effect reflects sustained visual perception it should positively correlate with the improvement observed for genuinely longer visual stimuli. Results showed that detection sensitivity (d′) for the 24 ms visual stimulus was significantly enhanced when paired with longer auditory stimuli ranging from 60 to 96 ms duration. The visual detection performance dropped to baseline levels with 190 ms sounds. Crucially, the enhancement for auditory durations 60–96 ms significantly correlates with the d′ enhancement for visual stimuli lasting 60–96 ms in the control condition. We conclude that the duration of co-occurring auditory stimuli not only influences the perceived duration of visual stimuli but reflects a genuine sustain in visual perception.

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.
