“…The symptoms of disintegration on serial tasks have been reported to be more frequent in the performances of anxious subjects than control subjects in a number of other tasks that can be regarded as belonging to the "most demanding" category. These are: serial coding (Cohen, 1952;Katchmar, Ross, & Andrews, 1958;Lewinski, 1945;Payne, in press), paced problem solving (Easterbrook, 1953;Kelly, 1932), visible maze tracing (Foulds, 1951;Karpeles, 1932;Porteus, 1956), tracking with preview (Clarke, 1955;Himmelweit, 1947), mirror drawing (Beier, 1951;Wechsler & Hartogs, 1954;Wright, 1954), syntactic speech (Kelly, 1932;Luria, 1932), and, of course, the Luria association-motor task (Clarke, 1955;Luria, 1932). Since these effects could be produced by reduced receptor-effector spans, it may be that they too reflect the reduction in range of cue utilization that is expected with emotion.…”
