Cognitive performance and development is negatively correlated with fixation duration patterns during infancy, and evidence suggests that long-looking infants may process visual information more slowly than short-looking infants. 3 experiments described here tested the possibility that these differences may be due to differential sensitivity to global and local visual information. Infants were administered discrimination and generalization tasks involving global and local information at varying levels of familiarization time. Results indicated that 4-month-olds process visual information in a global-to-local sequence. Both long- and short-looking infants were sensitive to both types of information, although long lookers required additional familiarization time to match the performance of short lookers. Finally, apparent "generalization" of global information at brief familiarization levels was traced to insensitivity to local stimulus properties. The results do not support the hypothesis that long- and short-looking infants are differentially sensitive to global versus local visual information at 4 months of age.
认知能力的表现和发展与婴儿期的注视持续时间模式呈负相关,有证据表明,长时间注视的婴儿处理视觉信息的速度可能比短时间注视的婴儿慢。这里描述的3个实验测试了这些差异可能是由于对全局和局部视觉信息的不同敏感度的可能性。在不同的熟悉时间水平下,对婴儿进行涉及全局和局部信息的辨别和泛化任务。结果表明,4个月大的婴儿以从全局到局部的顺序处理视觉信息。长时间注视和短时间注视的婴儿对这两种信息都很敏感,尽管长时间注视的婴儿需要额外的熟悉时间才能与短时间注视的婴儿的表现相匹配。最后,在短暂熟悉水平下全局信息的明显“泛化”可追溯到对局部刺激属性的不敏感。结果不支持4个月大时,长时间注视和短时间注视的婴儿对全局与局部视觉信息有不同敏感度的假设。
