Document Summary
Memory and rehearsal: short term memory, or working memory, distinguishing between short and long term memories. If you are calculating numbers 1+1=2, 2+2=3, and so on, you must always remember the last number: delayed matching to sample. Experiment: 3 circles, the one in the middle is lit either red or green. Sample stimulus: the colour that lights up is the sample. Comparison stimulus: the left and right keys are comparisons. Pigeons and other animals had no problem matching the sample and comparison. Experiment 2: sample is lit and then goes off, after some time the comparison. The delay can tell us how long a species can retain memory in their short term. There are stimuli that can interfere with memory. Retroactive- new material interferes with the memory of some previously. Proactive- when previously learned material impairs your ability to learn learned material something new colours. Retroactive in dmts- during delay present the subject with a whole bunch of.
