  • 摘要:

    Developmental characteristic of the visual search was examined through eye movement recordings detected by the scleral reflectional method. Healthy children aged 6 to 11 years participated in the experiment. A subject was asked to find a figure identical to the standard one presented at the center of the screen, from the four optimal figures presented at equi-distant locations in the four screen corners (Cohen 1981). Three different distance conditions were used, i.e. 3°or 6°or 12°. The main results were as follows: (1) Subjects tended to find the target figure with less numbers of fixations under the 3°condition.(2) In the early stage of searching, 6 year-old group tended to fixate the standard figure more frequently.(3) An average duration of a fixation decreased significantly up to 8 years old. It was inferred that an efficient strategy in visual searching might be stabilized at about 8 years optimally utilizing the visual informations within a limited short time. This strategy may be further supplemented with the effective retrieval of the visual memories.
