Reversal learning and set-shifting tasks. The (a) number of days and (b) errors to reach criterion performance (80% correct responses) in each of the sequential visual discrimination tasks in juvenile non-human primates (NHPs) exposed one (1×) or three (3×) times to isoflurane during infancy and in controls (Ctr). Tri = triangle (initial correct stimulus); Rec = rectangle (first reversal); Tri2 = second reversal, with triangle as correct stimulus; Rec2 = third reversal, with rectangle as correct stimulus; Green = set-shifting to colour, with green as correct stimulus; Red = colour reversal, with red as correct stimulus. Data are means (standard deviation); n (NHPs): Ctr: 7; 1×: 8; 3×: 4.
