A recent report of one‐trial learning in a group of saddle‐back tamarins ( Saguinus fuscicollis ) conflicted with views of learning set formation based on traditional techniques employing isolated subjects. An experiment is reported in which a group of Guinea baboons ( Papio papio ) was given a series of discrimination and habit reversal tasks. Both one‐trial learning and learning set formation occurred. Analysis of spatial behavior revealed that the group learned in a single trial to discriminate stocked from unstocked zones. Improvement in successes (reinforced “digging”) was progressive but not rapid, indicating learning set formation. It appears that outcomes depend on the behavioral variables chosen.
