PSYC 3030 : Test 3 Notes
Document Summary
Mckellar (1972) surveyed 500 adults and found that: 97% reported visual imagery, 93% reported auditory imagery, 74% motor, 70% tactile, 66% olfactory, 64% gustatory. Paired-associate learning: paivio (1963, pairs of concrete (imageable) words are remembered better than pairs of abstract words. Similar experiments have been done with meaningless shapes: cooper (1975, same results. When more rotation is required, more brain areas are activated. Mental rotation has been widely studied, and many details have been learned : familiar objects are easier to rotate, blurry images are harder to rotate, people with less spatial ability are twice as slow and rotate along rigid axes. In all cases, the analogy to physical rotation remains. So, mental rotation data seem to support the analog view : further evidence: imagery and size. In experiment 2, kosslyn asked people to imagine the rabbit next to a huge fly (size of an elephant) or a teeny elephant (size of a fly)
