When and how do infants learn color words? It is generally supposed that color words are learned late and with a great deal of difficulty. By examining infant language surveys in British English and 11 other languages, this study shows that color word learning occurs earlier than has been previously suggested and that the order of acquisition of…

Infants must learn about many cognitive domains (e.g., language, music) from auditory statistics, yet capacity limits on their cognitive resources restrict the quantity that they can encode. Previous research has established that infants can attend to only a subset of available acoustic input. Yet few previous studies have directly examined infant…

Infants' visual short-term memory (VSTM) for simple objects undergoes dramatic development: Six-month-old infants can store in VSTM information about only a simple object presented in isolation, whereas 8-month-old infants can store information about simple objects presented in multiple-item arrays. This study extended this work to examine…

This study investigated the relationship between task difficulty and ability level as a factor in producing imitative behavior in infants. A total of 28 toddlers, ranging in age from 14 to 28 months, participated in the study. (Author/JMB)

Results of three experiments support the conclusion that tasks involving the localization of objects or events from mirror images are not direct indices of self-recognition among children between 14 and 22 months of age. Rather, they indicate the skill of infants in using the mirror as a perceptual tool. (RH)

To demonstrate a relationship between rate of habituation and complexity levels, 11-week-old infants (N=51) were each given a rate-of-habituation and complexity-level test. Rapid habituators looked longer at complex patterns. Irregular habituators responded randomly to tests or resembled slow habituators in terms of complexity preferred. (ST)

Describes two studies which tested the hypothesis that short simple sentences addressed to children are the result of children signaling non-comprehension for longer, complex utterances. (JMB)

To determine whether infants can form face expression categories, groups of infants 18 to 24 weeks old, along with those 30 weeks old, were habituated by the infant control procedure to photographs of four different female faces, each with an identical expression (happiness or surprise). Results are discussed in terms of age and sex differences.…

In comparison with full-term infants, seven-month-old high-risk preterm infants exhibited deficits in visual recognition memory and in the ability to recruit, sustain, and shift attention. (RH)
