- Positivity Ratings of Social Images [ Time Frame: End of study (time 0 and approximately 4 weeks later), week 4 reported. ]Using the International Affective Picture System (IAPS; Lang et al. 1999), participants viewed standardized positive, negative and neutral pictures from the IAPS. The negative and positive images were matched on degree of valence and arousal. An Evaluative Space Grid rating followed each picture to collect subjective reactions. Ratings are on a 9-pt scale. The range of the scale is from 1 to 9 (Min score 1, max score 9). The total score is reported. Higher numbers represent more positive valence or greater arousal. Drug treatment: within-subjects; every participant received all drug doses, counter-balanced.
