Results.

<p>(<b>A</b>) Mean EDA induced by auditory and tactile stimuli during conditioning phase shown for the two conditioning groups (CS+: 250 Hz vs. CS+: 2 kHz). SE is indicated. (<b>B</b>) Average EDA induced by CS+ and CS- in the conditioning phase (the two conditioning groups combined) at different trials. Standard errors of the means are indicated. (<b>C</b>) Interaction effect of conditioning group and sound on loudness (top), fear (middle) and valence (bottom) judgments. Main effects and grand means are removed. SE is indicated.</p

Timeline of a single conditioning trial.

<p>After the presentation of an auditory stimulus that was 5 seconds long tactile stimulus was presented. Between the onsets of two consecutive trials there were 11 seconds. Figure also shows the time windows in which EDA was scored.</p

Mean valence, fear and loudness ratings for the auditory stimuli according to the two conditioning groups (CS+: 250 Hz vs. CS+: 2 kHz).

<p>Fear and loudness ratings are z-scores. Valence ratings are on a scale from 1 to 9.</p
