Extradimensional transfer of learning-set formation in stumptailed monkeys

Stumptailed macaques were trained (original learning) on a series of two-choice discrimination problems in which form (color) was relevant and color (form) irrelevant and variable within and between problems, i.e., tow values from the irrelevant dimension were used on each trial; these values varied...

Zusammenfassung:Stumptailed macaques were trained (original learning) on a series of two-choice discrimination problems in which form (color) was relevant and color (form) irrelevant and variable within and between problems, i.e., tow values from the irrelevant dimension were used on each trial; these values varied randomly with respect to the reinforcer and were changed from problem to problem. After the Ss reached a high level of performance, the relevant and irrelevant dimensions were reversed (shift learning). Performance levels were substantially and significantly higher during shift learning than during original learning, suggesting extradimensional transfer of learning-set formation. An additional control group was given extended training on a single color discrimination problem and then a series of form discriminations. The results for this group indicated that adaptation to testing may account for some of the transfer obtained, but far from all of it.
