Lewis, Michael; And Others – Developmental Psychology, 1985
Compares attachment relationships of infants at 12 months to their visual self-recognition at both 18 and 24 months. Individual differences in early attachment relations were related to later self-recognition. In particular, insecurely attached infants showed a trend toward earlier self-recognition than did securely attached infants. (Author/NH)

Lewis, Michael; And Others – Child Development, 1989
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)

Carmody, Dennis P.; Bendersky, Margaret; Dunn, Stanley M.; DeMarco, J. Kevin; Hegyi, Thomas; Hiatt, Mark; Lewis, Michael – Child Development, 2006
The relations among early cumulative medical risk, cumulative environmental risk, attentional control, and brain activation were assessed in 15-16-year-old adolescents who were born preterm. Functional magnetic resonance imaging found frontal, temporal, and parietal cortex activation during an attention task with greater activation of the left…

Ramsay, Douglas; Lewis, Michael – Child Development, 2003
Examined relations between reactivity (peak response) and regulation (response dampening) in 6-month-olds' cortisol and behavioral responses to inoculation. Found that reactivity and regulation were unrelated for both cortisol and behavior, suggesting both measures are needed to characterize more accurately infant response to stress. Found…

Lewis, Michael; And Others – New Directions for Child Development, 1989
Reports a study of 110 newborn infants' responses to the heelstick procedure to draw blood samples, and of the responses of 40 of those infants to their first inoculations at two months of age. Discusses measures of distress; stability of reactivity across time; and individual differences and health of the infant as factors in reactivity. (NH)

Freedle, Roy; Lewis, Michael – 1971
The purpose of this paper is to outline some application of the Markov Process to the study of state and state changes. The essence of this mathematical concept consists of the analysis of sequences of infant responses in interaction with its environment. Categories can be defined which reflect the joint occurrence of an infant's behavior (or…

Lewis, Michael; Feiring, Candice – Child Development, 1989
Studies 174 mother-infant dyads to determine the relation between 3-month-old infant, mother, and mother-infant interaction behavior and later attachment behavior. Individual infant differences in sociability at 3 months were found to be related to avoidant behavior and A-type attachment. (RJC)

Lewis, Michael; Brooks-Gunn, Jeanne – Intelligence, 1981
The authors discuss methodological and theoretical issues in psychological investigations of infant attention, fixation times, habituation, and intelligence. A consensus on how to measure individual differences in habituation has not been reached. The relation between IQ and attention is discussed. (RD)

Lewis, Michael; And Others – Developmental Psychology, 1990
Examined facial expressions in relation to cognition in infants 2 to 8 months of age. A total of 48 subjects received an audiovisual stimulus contingent on arm movement, whereas 32 infants did not control the stimulus. Infants in the contingent group expressed greater interest and joy during learning and greater anger during extinction. (RH)

Feiring, Candice; Taska, Lynn; Lewis, Michael – Developmental Psychology, 2002
Examined impact of shame and attributional style on adjustment following sexual abuse. Found that once adjustment at discovery was accounted for, shame and attribution style explained additional variation in adjustment 1 year later; abuse severity did not. Relations between abuse severity and subsequent depressive symptoms and self-esteem were…

Bendersky, Margaret; Lewis, Michael – Developmental Psychology, 1994
Examined the impact of 2 environmental factors--social class and family risk levels--and 2 biological factors--intraventricular hemorrhage (IVH) and medical risk--on the cognitive and motor development of 175 preterm infants. Family risk, early medical risk, and the interaction of family risk and IVH were found to be significant predictors of…
