婴儿期的认知表现和发展与注视持续时间模式呈负相关，有证据表明，长眼婴儿处理视觉信息的速度可能比短眼婴儿慢。本文描述的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性造成的可能性。婴儿在不同程度的熟悉时间内接受涉及全局和局部信息的区分和概括任务。结果表明，4个月大的婴儿处理视觉信息的整体到局部的顺序。长眼和短眼婴儿对这两种信息都很敏感，尽管长眼婴儿需要额外的熟悉时间来匹配短眼婴儿的表现。最后，明显的“泛化”的全球信息在简短的熟悉程度被追溯到不敏感的地方刺激属性。研究结果不支持长脸和短脸婴儿在4个月大时对全局视觉信息和局部视觉信息的敏感性不同的假设。
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.
