Investigates the relationship between self-recognition and self-evaluative emotions in two studies on 27 children aged 9-24 months and 44 children aged 22 months. The results of both studies indicate that embarrassment but not wariness was related to self-recognition. (RJC)

Investigated 314 young children who had neonatal hyperbilirubinaemia. Results indicated that these children managed less well in neurological and psychological tests, had poorer school marks, and more often attended special classes than did members of the control group. (RJC)

Two studies found infants' scores on the Range of State Cluster of the Neonatal Behavioral Assessment Scale with Kansas Supplements to correlate significantly with visual discrimination performance at three months of age. The correlation with behavioral state organization contradicted the prediction that orientation scores would predict visual…

Three experiments using the familiarization-novelty preference procedure confirmed the hypothesis that three-month-old infants could form categorical representations of spatial relations above and below. The infants, after being shown a familiarization diagram with a dot appearing in multiple locations below a line, showed a preference for a novel…

In one experiment, most four to eight year olds overattributed knowledge to a preverbal baby who heard an informative message. In a second experiment, six and eight year olds acknowledged differences in babies' and adults' interpretations of a message that was not obviously informative. (BC)

Compared interstimulus interval (ISI) eye movements of 3-month-olds viewing an alternating picture sequence with those of infants viewing an irregular sequence. Found that all infants exhibited shifts during ISIs. Repetitive saccades declined while alternating and anticipatory saccades increased in alternating sequences. ISI shift frequency did…

This study utilized the head-turn preference procedure in four experiments to determine whether 1-year-old infants could extract and remember information from auditory strings produced by miniature artificial grammar. Findings indicated that subjects generalized to the new structure by discriminating new grammatical strings from ungrammatical ones…

Comments on Needham's research of infant perception by focusing on the types of evidence needed to make inferences concerning infant cognition. Considers the history of scientific explanations of animal cognition as nearer to infant cognition, and the high level of creativity required in proposing and testing alternative explanations of infant…

Discusses Needham's findings by asserting that they extend understanding of infant perception by showing that the memory representations infants draw upon have bound together information about shape, color, and pattern. Considers the distinction between two senses of "recognition" and asks in which sense object recognition contributes to object…

Explores how experiences after birth exert a dramatic and precise impact, physically determining how the intricate neural circuits of the brain are wired, in particular, in areas of language and vocabulary. Discusses the brain's acute vulnerability to trauma such as under or over stimulation or abuse. (HTH)

Jones and Herbert describe research on deferred imitation and how this research reflects on the development of explicit memory in infancy. The article raises several interesting questions about how the medial temporal lobe memory system develops. In this commentary, I discuss some of the additional theoretical and empirical questions that are…

Infants aged 3-5 months (mean of approximately 4 months) were given a novel anticipatory looking task to test object permanence understanding. They were trained to expect an experimenter to retrieve an object from behind a transparent screen upon hearing a cue (''Doors up, here comes the hand''). The experimenter then hid the object behind one of…

Infants first generalize across contexts and cues at 3 months of age in operant tasks but not until 12 months of age in imitation tasks. Three experiments using an imitation task examined whether infants younger than 12 months of age might generalize imitation if conditions were more like those in operant studies. Infants sat on a distinctive mat…

Current work has yielded differential findings regarding infants' ability to perceptually detect the causal structure of a means-end support sequence. Resolving this debate has important implications for perception-action dissociations in this domain of object knowledge. In Study 1, 12-month-old infants' ability to perceive the causal structure of…

This paper aims to compare cognitive development in humans and chimpanzees to illuminate the evolutionary origins of human cognition. Comparison of morphological data and life history strongly highlights the common features of all primate species, including humans. The human mother-infant relationship is characterized by the physical separation of…
