其他摘要：The nature of searching items was investigated in a perceptual task; the reaction time function was studied in re1ation to the numbers of items in the figures to be compared, giving judgements of "same" or "dif- Icrent". It was required the transformation of the stimuli base rule, and in half of the stimuli, rotation of the figures in the imagination. Data show that: (a) only in the case of non-rotated and real figures, the search was exhaustive; (b) in the cases of false non-rotated, and real rotated figures the search was autoterminated; (c) in the false rotated figures there isan ínverse proportional function. It is suggested an ínterpretatíorrabout the the manner way in wich subjects carry out the task
