LEARNING IN HONEYBEES (APIS-MELLIFERA) AS A FUNCTION OF AMOUNT OF REWARD - ACQUISITION MEASURES

Foraging honeybees were trained individually to discriminate between targets that contained 5-μl or 20-μl drops of sucrose solution. Measures of resistance to extinction supported the assumption that the slope of the acquisition function increases with amount of reward while its asymptote remains the same. Honeybees tended to respond less rapidly after large than after small reward, which does not require an associative interpretation. -from Authors
