80名5.5至12.5个月大的婴儿参加了4个挑战短期视觉空间记忆（STVM）的延迟反应程序，其中2个改变了呈现和搜索之间的时间，2个改变了位置的数量。在每种类型的挑战中，1项任务需要凝视反应，1项任务需要伸手反应。从5.5个月到8个月，STVM性能几乎没有改善，从8个月到12个月，正确率呈线性改善，总体STVM性能占年龄方差的66%。搜索多个位置的改进落后于跨越更长延迟的改进。视觉和手动任务的记忆分数没有变化。持续性是最大的达到反应，增加挑战，并随着年龄的增长而下降。
Eighty 5.5-to 12.5-month-old infants participated in 4 delayed-response procedures challenging short-term visuospatial memory (STVM), 2 that varied the time between presentation and search and 2 that varied the number of locations. Within each type of challenge, 1 task required a gaze response and 1 required a reach response. There was little improvement in STVM performance from 5.5 to 8 months and linear improvement in the percentage correct from 8 to 12 months, with overall STVM performance accounting for 66% of the variance in age. Improvement in searching multiple locations lagged behind improvement in spanning longer delays. Memory scores did not vary for the visual and manual tasks. Perseveration was greatest for reach responses, increased with challenge, and decreased with age.
