Infancy predictors of preschool and post‐kindergarten executive function
Developmental Psychobiology - Tập 55 Số 5 - Trang 530-538 - 2013
Jessica H Kraybill, Martha Ann Bell
AbstractLittle is known about factors that promote optimal development of executive function (EF) skills. The focus of this study was associations among early maternal behaviors, infant frontal brain electrical activity, and child EF at age 4 and following kindergarten. Infant frontal electroencephalogram was collected from 56 infants at 10 months of age and matern...... hiện toàn bộ
EEG power and coherence during preschoolers' performance of an executive function battery
Developmental Psychobiology - Tập 53 Số 8 - Trang 771-784 - 2011
Margaret M. Swingler, Michael T. Willoughby, Susan D. Calkins
AbstractThe current study investigated a set of abilities collectively referred to as executive function (EF). Substantial improvement in EF ability occurs between 3 and 6 years of age (e.g., Carlson [2005] Developmental Neuropsychology, 28(2):595–616). This improvement is thought to reflect changes in brain development, especially in areas of prefrontal cortex and...... hiện toàn bộ
Preliminary evidence for the effects of environmental complexity on hybridization of rat brain RNA to rat unique DNA
Developmental Psychobiology - Tập 8 Số 2 - Trang 171-178 - 1975
Lynda Uphouse, James Bonner
AbstractHybridization to unique DNA by RNA from brain or liver of rats given varying degrees of experience was investigated. RNA from brain of environmentally enriched rats hybridized to more unique DNA than did brain RNA from nonenriched controls. No significant differences were observed with liver RNA. This provides preliminary evidence for an increased transcrip...... hiện toàn bộ
Effects of early life NICU stress on the developing gut microbiome
Developmental Psychobiology - Tập 61 Số 5 - Trang 650-660 - 2019
Amy L. D’Agata, Jing Wu, Manushi Welandawe, Samia Valéria Ozorio Dutra, Bradley Kane, Maureen Groër
AbstractSuccession of gut microbial community structure for newborns is highly influenced by early life factors. Many preterm infants cared for in the NICU are exposed to parent–infant separation, stress, and pain from medical care procedures. The purpose of the study was to investigate the impact of early life stress on the trajectory of gut microbial structure. S...... hiện toàn bộ
Individual olfactory signatures as major determinants of early maternal discrimination in sheep
Developmental Psychobiology - Tập 24 Số 3 - Trang 151-158 - 1991
R.H. Porter, Frédéric Lévy, Pascal Poindron, Michelina Litterio, B. Schaal, Carlos Beyer
AbstractResponses of recently parturient ewes to their familiar versus separated (i.e., unfamiliar) twin lambs were observed in an attempt to elucidate further the characteristics of the phenotypic traits (signatures) mediating maternal recognition and bonding. Ewes responded more positively to their familiar lamb than to its twin that had been isolated at birth. N...... hiện toàn bộ
Temporal dynamics of arousal and attention in 12‐month‐old infants
Developmental Psychobiology - Tập 58 Số 5 - Trang 623-639 - 2016
Sam Wass, Kaili Clackson, Kaya de Barbaro
ABSTRACTResearch from the animal literature suggests that dynamic, ongoing changes in arousal lead to dynamic changes in an individual's state of anticipatory readiness, influencing how individuals distribute their attention to the environment. However, multiple peripheral indices exist for studying arousal in humans, each showing change on ...... hiện toàn bộ
The influence of nutrition on neural and behavioral development. I. Critical review of some data on the growth of the body and the brain following dietary deprivation during gestation and lactation
Developmental Psychobiology - Tập 3 Số 4 - Trang 281-301 - 1970
Joseph Altman, Gopal D. Das, Kiran Sudarshan
AbstractThe scanty data available on the effects of undernutrition during gestation and lactation upon neural development in man are reviewed briefly. This review is followed by a description of the various techniques that have been employed for the experimental undernutrition of laboratory animals. Then a detailed review is given of the effects of dietary deprivat...... hiện toàn bộ
The effect of chronic protein malnutrition on trans‐callosal evoked responses in the rat
Developmental Psychobiology - Tập 8 Số 6 - Trang 503-509 - 1975
William B. Forbes, Oscar Resnick, Warren C. Stern, Joseph D. Bronzino, Peter J. Morgane
AbstractStudies were carried out on the trans‐callosal evoked response in rats born of dams fed either a low (8%) or normal (25%) protein diet beginning 5 weeks prior to mating and throughout gestation and lactation. After weaning, pups were fed the same diets as their mothers. Bipolar (surface vs depth) stainless steel stimulating and recording electrodes were pos...... hiện toàn bộ
The postnatal development of behavioral states in the rat
Developmental Psychobiology - Tập 3 Số 4 - Trang 267-280 - 1970
Albert Gramsbergen, P Schwartze, H.F.R. Prechtl
AbstractThe ontogeny of behavioral state cycles in white rats has been studied from their 2nd to their 30th day of life. A scale of 5 behavioral states, based on operationally defined categories was employed: state 1: quiet sleep; state 2: active sleep; state 3: quiet wakefulness; state 4: active wakefulness and state 5: locomotion. The percentage of time which you...... hiện toàn bộ
The influence of nutrition on neural and behavioral development. IV. Effects of infantile undernutrition on the growth of the cerebellum
Developmental Psychobiology - Tập 5 Số 2 - Trang 111-122 - 1972
Joseph Altman, Barbara S. McCrady
AbstractThe morphological development of the cerebellum was examined with quantitative histological techniques in rats which were nursed from birth by mothers that had free access to food during lactation or were fed during that period 40 or 20% of the average ad lib diet. Little or no retardation was observed in the development of the cerebellum except in its germ...... hiện toàn bộ
