Strategy choice and strategy training in sentence—picture verification

On each of three days, high and low spatial ability subjects verified the truth of simple sentences as descriptions of simple pictures. A two-reaction time version of a sentence picture verification task was used. On the first day (Free condition) 32 subjects were allowed free choice of strategies. The data replicated a previous finding of individual differences in strategy usage, with a hypothesized pictorial strategy used by 11 subjects, and a linguistic strategy used by the rest. Training in a pictorial and a linguistic strategy was counterbalanced over the second and third days, and the subjects yielded data in each condition virtually identical to their Free condition counterparts. The psychometric data provided additional support for the strategy distinction.
