ALLIPRANDINI, Paula Mariza Zedu; PAULA, Andrea de  and  BARCELLOS, Ricardo Tadeu Sandrini. Visual and haptic memory for length and area estimates. Ciênc. cogn. [online]. 2009, vol.14, n.1, pp. 02-13. ISSN 1806-5821.

The power function is applicable to the study of the memory process. Based on this premise, and on the need for studies of visual and haptic memory mechanisms, this study had the aim to verify, in the memory condition, the exponents of the power function of the visual and haptic modalities for length/thickness and area. This study involved the information acquisition and remembering phases and employed five different time intervals between both phases. Estimates of 200 participants were made according to the magnitude estimation method. The results showed that there were no significant differences among the visual (M=0.57) and haptic (M=0.53) sensorial modalities or between the length (M=0.56) and area (M=0.54) stimuli. Significant differences were observed among the different time intervals. There was a significant interaction between the sensory modality effects and stimuli, which suggests that the visual and haptic memory process is dependent on the stimulus characteristic, and that the exploration strategy and the presence of bimodal experience should be more intensely investigated as variables of the visual and haptic memory process.

Keywords : memory; visual; haptic; length; area.
