Abstract: | ![]() Gave independent groups of male hooded rats (n = 30) either (a) single alternation (SA) of reward and nonreward in the 1st goal box of a double runway and 100% reward in the 2nd goal box, (b) concurrent SA in both goal boxes, (c) SA in the 1st goal box and no experience in the 2nd runway, or (d) random 50% reward in the 1st goal box accompanied by 100% reward in the 2nd goal box. SA training in the 1st or in both segments of the double runway yielded reliable SA patterning wherever such training occurred. Concurrent SA training in both segments yielded the fastest development of patterning. "Frustration effects" in the 2nd runway were consistently greater following SA in the 1st goal box than following random reward and nonreward.
