A V O I D a N C E a N D M a Z E L E a R N I N G in Pigs 1

An experiment involving 120 pigs, with four pigs randomly selected from each of 30 litters, was conducted to determine the relationship between avoidance learning and water-maze learning, and to determine which pattern or patterns in a water-maze would reflect maximum differences in learning ability. Decreases in total errors and total latency indicated learning occurred on the non-alternating patterns. Significant correlations were observed among avoidance learning criteria and among water-maze learning criteria, but no significant correlations were observed between avoidance learning and maze learning criteria. Because of this correlation pattern two principal components were identified; one principal component was identified as a measure of avoidance learning ability and a second principal component was identified as a measure of water-maze learning ability.
