Document Summary
Push latch (r) to get out box (s) Instrumental behaviour - behaviour that occurs because it was previously effective in producing certain consequences. Thorndike (cid:862)a(cid:374)i(cid:373)al i(cid:374)tellige(cid:374)(cid:272)e(cid:863: puzzle boxes cat learns how to get out and get food: pushing lever, latch, string etc. Faster each time: strict avoidance of anthropomorphic interpretations of behaviour he observed, did not believe his animals were intelligently using insight to get out faster each time. Learning of a new s-r association instead: s = puzzle box, r = response whenever s occurs (push latch = escape) Modern approaches to the study of instrumental conditioning. Discrete-trial process discrete-trial procedures put subject in apparatus and then remove subject when instrumental response has been performed. Running speed how fast subject completes discrete-trial procedure. Latency time it takes subject to begin trial after being placed in the apparatus. Conditioned preference for mouse pups after mother was removed from goal box continued in a t maze.
