5 male albino rats were trained to turn right in a simple T-maze when motivated by 11.5 hours hunger, and to turn left when motivated by 47.5 hours hunger; 3 trials were given in each experimental period. The order of strong and weak motivation was mixed, but in general followed alternating periods of strong and weak hunger. The results indicate a statistically significant percentage of correct choices at a high level of confidence. Tests for generalization under 4-hour and 72-hour hunger also showed a statistically significant percentage of correct runs. The writers conclude that "different responses may be associated with differential strengths of the same drive." (PsycINFO Database Record (c) 2006 APA, all rights reserved)
