  • Transposition of line‐length discrimination in African penguins ( Spheniscus demersus ) 1

    Open AccessKAZUCHIKA MANABE, MINAMI MURATA et al.ARTICLEJapanese Psychological Research2009

    Four penguins ( Spheniscus demersus ) were trained to discriminate line length in a simultaneous discrimination task. After the birds' performances reached a discrimination criterion, the reinforcement ratio was decreased to .33. After the ratio of correct trials reached .90 in three successive sessions with a partial reinforcement procedure, probe‐test sessions were introduced. In the probe‐test trials, untrained lines were presented paired with…

    The effect of motivation on the gradient of stimulus generalization was examined, color light serving as a stimulus dimension and key-pecking response in the pigeon as a response measure. Three levels of food deprivation (47-, 24-, and 2-hr) were factorially arranged both in training and testing. The findings were:(1) The amount of generalization in terms of an absolute or a relative generalization gradient increases as a function of the drive le…
