Group choice: competition, travel, and the ideal free distribution

Article Abstract:

A study was conducted to examine the impact of forage distribution on competition in a flock of pigeons. The mechanism of flock distributed was directly correlated with comparisons between patches that were successive rather than simultaneous. Results suggested that whatever the mechanism of the flock's distribution, it produces results associated with the flock level phenomenon that does not mirror the behavior of the individuals.

Group choice: the ideal free distribution of human social behavior

Article Abstract:

An ideal free distribution analysis of group choice is useful and possible, and suggests group choice can be accounted for by individuals' tendencies to optimize reinforcement. These results support the theory that a ratio of foragers at two resource sites should equal the ratio of obtained resources.

Every reinforcer counts: reinforcer magnitude and local preference

Article Abstract:

Studies of pigeon behavior show that visit durations following reinforcers were longer after larger reinforcers than after smaller reinforcers. Visit durations were also longer after a series of same reinforcers than after other sequences.
