Reversal Design

Ss with a strong fear of snakes were taught to increase and decrease their skin resistance during practice sessions with a continuous visual display. Ss were not aware that they were increasing or decreasing their levels of skin resistance and attempted only to influence the magnitude of the multimeter display, the polarity of which was controlled by the experimenter. The study used a within-subjects reversal design to investigate whether bidirectional control could be acquired over skin resistance level. To investigate whether this acquired control could affect the magnitude of elicited pre-conditioned autonomic responses, a pre- and post-training comparison was made between the GSRs elicited during test sessions in which Ss viewed slides of snakes while attempting to influence their electrodermal activity with the assistance of the visual display. The results suggest that Ss are able to acquire voluntarily bidirectional control of their level of skin resistance with continuous visual feedback and that this control can either depress or facilitate the magnitude of pre-conditioned emotional responses as a function of visual feedback.

This is the first study to analyze variations in time estimation during 60 h of sleep deprivation and the relation between time estimation performance and the activation measures of skin resistance level, body temperature, and Stanford Sleepiness Scale (SSS) scores. Among 30 healthy participants 18 to 24 years of age, for a 10-s interval using the production method, we found a lengthening in time estimations that was modulated by circadian oscillations. No differences in gender were found in the time estimation task during sleep deprivation. The variations in time estimation correlated significantly with body temperature, skin resistance level, and SSS throughout the sleep deprivation period. When body temperature is elevated, indicating a high level of activation, the interval tends to be underestimated, and vice versa. When the skin resistance level or SSS is elevated (low activation), time estimation is lengthened, and vice versa. This lengthening is important because many everyday situations involve duration estimation under moderate to severe sleep loss. Actual or potential applications of this research include transportation systems, emergency response work, sporting activities, and industrial settings in which accuracy in anticipation or coincidence timing is important for safety or efficiency.

Level of anxiety as represented in skin resistance levels (SRLs) was measured 5 times throughout the day in 60 hospitalized schizophrenic patients. Ss were classified into 3 groups of varying lengths of history of schizophrenic disorder and further subdivided into groups remaining on tranquilizing medication and groups receiving no medication for 84 hr. prior to testing. The comparison group (medicated) mean SRL differed significantly from that of the experimental group (non-medicated) mean SRL thus demonstrating the relevant effect of removal of the experimental Ss from medication. The experimental Ss tended to show significantly less anxiety (increased SRLs) and more variable levels of anxiety (increased variation in SRL) as a function of increasing chronicity. These findings were interpreted as supporting Mednick's learning theory hypothesis regarding anxiety in schizophrenic disorder.

The combined interactions of mode and tempo on emotional responses to music were investigated using both self-reports and electroencephalogram (EEG) activity. A musical excerpt was performed in three different modes and tempi. Participants rated the emotional content of the resulting nine stimuli and their EEG activity was recorded. Musical modes influence the valence of emotion with major mode being evaluated happier and more serene, than minor and locrian modes. In EEG frontal activity, major mode was associated with an increased alpha activation in the left hemisphere compared to minor and locrian modes, which, in turn, induced increased activation in the right hemisphere. The tempo modulates the arousal value of emotion with faster tempi associated with stronger feeling of happiness and anger and this effect is associated in EEG with an increase of frontal activation in the left hemisphere. By contrast, slow tempo induced decreased frontal activation in the left hemisphere. Some interactive effects were found between mode and tempo: An increase of tempo modulated the emotion differently depending on the mode of the piece.
