Peer reviewedBoukydis, C. F. Zachariah; Burgess, Robert L. – Child Development, 1982
Examines the motivational or affective message and impact of infants' cries on nonparents, primiparous parents, and multiparous parents. Cries were organized into three levels (difficult, average, easy) by temperament ratings and spectographic analysis. Physiological and self-report responses to audiotapes of infants' cries were obtained from 36…

An infant control habituation-recovery procedure was used to study 3-month-old infants' discrimination of sad, happy, and surprise facial expressions. (Author/JMB)

Peer reviewedRader, Nancy; And Others – Child Development, 1980
Twenty-two infants (6.7 to 12.3 months old) were tested on a visual-cliff apparatus both crawling and in a walker. Results suggest a maturation-based explanation of cliff-avoidance in infants. (CM)

Peer reviewedTrehub, Sandra E.; Curran, Susanne – Child Development, 1979
Four groups of infants, 4 1/2 to 5 1/2 months of age, were presented with repeated speech stimuli which were synthesized exemplars of the sound, "baba," natural exemplars of "baba" or "kaba," or novel syllables on each trial. (RH)

Peer reviewedRamsay, Douglas S.; Lewis, Michael – Child Development, 1994
Infant cortisol and behavioral responses to receiving one versus two inoculations on one pediatric office visit were observed at two and six months of age. The findings indicate a developmental trend for a decline over age in adrenocortical reactivity to inoculation for infants showing a cortisol release following perturbation. Results were…

Peer reviewedHofstadter, Maura; Reznick, J. Steven – Child Development, 1996
Assessed delayed-response performance in 120 infants 7, 9, and 11 months old. Correct response was identified as either retrieval of a hidden object or a gaze toward its location. Performance improved with age, was above chance for each age group in each condition, and was more often correct for gaze response, suggesting a significant effect of…

Peer reviewedMcGuire, Iris; Turkewitz, Gerald – Child Development, 1978
The relationship between visual stimulus intensity and finger movements was examined in infants ranging in age from 10 to 15 weeks and from 20 to 25 weeks. Infants were shown a cone that varied in size, brightness, and distance from them. (Author/JMB)

Purpose of this experiemnt was to systematically investigate the behavioral effects of vertical rocking at different frequencies up to 1.5 Hz. (Authors/CB)

Peer reviewedKagan, Jerome – Child Development, 1997
Notes that 4-month olds who show a low threshold to become distressed and motorically aroused to unfamiliar stimuli are more likely than others to become fearful and subdued during early childhood, while infants who show a high arousal threshold are more likely to become bold and sociable. Considers implications for psychopathology and relation…

Peer reviewedHornik, Robin; And Others – Child Development, 1987
Studied were the responses of infants to new toys presented with either positive, negative, or neutral affective displays by mothers. Responses to stimulus toys were compared with responses to free play toys. Maternal displays influenced responses only to stimulus toys. (PCB)

Peer reviewedFagen, Jeffrey W. – Child Development, 1980
Four-month-old infants' stimulus preferences were assessed using an operant paradigm with mobile reinforcers of different colors (blue, green). (Author/MP)

Peer reviewedLewis, Michael; Ramsay, Douglas S. – Child Development, 1997
Examined whether early differences in stress reactivity were related to self-recognition at 18 months. Found that self-recognition was related to greater cortisol response and less rapid quieting at 6 to 18 months, whereas cortisol and quieting responses of 2- to 4-month-olds did not differentiate self-recognizers and non-self-recognizers,…

The relationship between neonatal visual information-processing and the burst-pause pattern of nonnutritive sucking was explored. (JMB)
