A multiple habituation paradigm was used to determine whether 10- to 12-month-old infants were able to discriminate between visual arrays differing only in their numerosity. (Author/RH)

Four-, six, and eight-month-old infants' perception of the multimodal features of the human face was investigated. Results show that speech-related exaggerated prosody cues facilitate detection of the audible features of multimodally represented faces, but not until six months of age. (Author/DR)

The primary purpose of this study was to examine whether a general perceptual model developed by Vitz and Todd (1971), capable of dealing with multiple determinants of attending, is useful for understanding infant attending. The model, previously used in research with adults, assumes that perception can be represented as a stochastic sampling…

This study uses a habituation paradigm to systematically investigate the discrepancy hypothesis with male and female new borns. In addition, multiple visual response measures are used in monitoring the habituation process and the infant's response to various degrees of novelty. Ss were 36 apparently normal newborns (half of each sex) ranging in…

The purpose of this study was to cross-sectionally and longitudinally examine the developmental process of search behavior in infancy. Subjects were 23 Japanese normal infants (11 males and 12 females) who were individually tested once a month from the age of six to 13 months in laboratory settings. Small toys and three white opaque cubic boxes…
