Relation between response and outcome, or the contingency.

It(cid:859)s like lat(cid:272)h pulli(cid:374)g (cid:449)as response that belonged more with escaping from something than response of yawning; doubtful that any creature is able to escape anything by yawning. Sevenster, 1973: study using a little territorial fish called the three-spined stickleback; fish builds nests in territories where it defends aggressively from other males and courts passing females. Instead, responses that fit well with the situation/reinforcement have a learning advantage. If true, then should be possible to predict which responses will be easy to increase with food reinforcement by studying what responses animal naturally does when feeding system is activated.
