Document Summary
Conditioning is typically best with short delayed conditioning. Backward conditioning can result in inhibitory conditioning. Trace: effective but not as effective of short delayed. Experiments: plotted on y axis how well animal learned and x: groups who had varying intervals between cs us. In the data see, they peak and then go down, inverted u function, 0 doesn"t produce super effective learning, have optimal cs us interval that produces condiitonng but when cs us interval gets longer, not as productive. Timing depends on preparation which may have something to do with the response itself. Time between cs on and us on. Experiment: learning proceeds best when you have a high iti/cs-us ratio. Inverted u curve for optimal cr acquisition. Cue was paired with shock and looking at suppression ratio with same cue in every case but magnitude of the shock was different (low to high foot shock amplitudes) With minor foot shock, animals didn"t learn much at all.
