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
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 development of the EEG in the rat
Developmental Psychobiology - Tập 9 Số 6 - Trang 501-515 - 1976
Albert Gramsbergen
AbstractThe development of the electroencephalogram EEG and, especially, behavioral state‐specific EEG patterns was studied in white and black hooded rats of the Lister strain, aged 9‐30 days. Movements of the rat were recorded and the behavioral state was monitored by means of a push‐button device. The EEG was collected when the rat was in State 1 (regular respira...... hiện toàn bộ
The development of intersession habituation and emergence in socially reared and isolated rats
Developmental Psychobiology - Tập 8 Số 6 - Trang 553-559 - 1975
Dorothy Einon, Michael Morgan, Barbara J. Sahakian
AbstractMale and female hooded rats were weaned at 17 days and then reared in isolation or in social groups. Intersession habituation of locomotor activity in the open field was tested at 15, 25, and 45 days. Contrary to some previous reports, the 15‐day‐old animals showed significant habituation. At 45 days, however, the isolates showed very little habituation com...... hiện toàn bộ
Odor‐aversion learning by rats following LiCl exposure: Ontogenetic influences
Developmental Psychobiology - Tập 16 Số 1 - Trang 13-22 - 1983
Jerry W. Rudy, Martin D. Cheatle
AbstractThe influence of LiCl preexposure on odor‐aversion conditioning produced by an odor‐LiCl pairing was studied in rats 7–31 days old. LiCl preexposure interfered with the acquisition of the odor aversion in both young and old pups. The time course of this effect depended, however, on the age of the pups. It lasted much longer (over 24 hr) if pups 8–17 days ol...... hiện toàn bộ
Short‐term exposure to an odor increases its subsequent preference in preweanling rats: A descriptive profile of the phenomenon
Developmental Psychobiology - Tập 17 Số 4 - Trang 407-422 - 1984
Patricia A. Caza, Norman E. Spear
AbstractFive experiments assessed the change in preference for an ambient odor after a brief period of exposure to that odor. Three minutes of exposure to a novel odor consistently increased subsequent preference for that odor. This effect occurred in preweanling rats 10 and 15 days of age even though, relative to the nest, the conditions of exposure were probably ...... hiện toàn bộ
Conditioning of aversion to alcohol orosensory cues in 5‐ and 10‐day rats: Subsequent reduction in alcohol ingestion
Developmental Psychobiology - Tập 19 Số 3 - Trang 175-183 - 1986
Juan Carlos Molina, Heather Hoffmann, Norman E. Spear
AbstractTwo experiments examined in 5‐ and 10‐day‐old rat pups the impact of alcohol olfactory aversions upon subsequent alcohol intake. In Experiment 1 it was observed that at both ages, animals given a single pairing of alcohol odor and LiCl subsequently consumed less alcohol than those in any of 4 control conditions (alcohol odor unpaired with LiCl, alcohol odor...... hiện toàn bộ
