Outcome measures: Generalised avoidance. Generalised avoidance was estimated as responding to GS1 relative to GS2. A positive score indicates more avoidance of GS1. A negative score indicates more avoidance of GS2. Relative avoidance of GS1 was greater in the Acquisition context than in the Novel context. This was evident in both training groups. Competing behaviours. There was no effect of stimulus on competing behaviour. Overall, competing behaviours were more frequent in the Novel context than in the Acquisition context. Generalised approach. Generalised approach was estimated as responding to GS2 relative to GS1. A positive score indicates more approach of GS2. A negative score indicates more approach of GS1. Relative approach of GS2 was greater in the Acquisition context than in the Novel context. This was evident in both groups. ○ = Individual data points; X = mean; ◊ = median. Edges of the box are the 25th and 75th percentiles. Whiskers extend to extreme value not considered to be an outlier.
