|Adult judgments of infant expressive behavior: Facial, vocal, and body actions.
||Adult judges were presented with videotape segments showing an infant displaying facial configurations hypothesized to express discomfort/pain, anger, or sadness according to differential emotions theory (Izard, Dougherty, & Hembree, 1983). The segme...
|Behavioral Science, Engineering and Poetry Revisited
||Forty years ago, Lehrman (1971) identified 2 orientations to the study of animal behavior. The natural history orientation conducted field and lab research designed to reveal how animals cope with the circumstances of their natural environment. Such ...
|Bimanual role differentiated toy play during infancy.
||Role-differentiated bimanual manipulation requires each hand to perform different, but complementary, actions on one or more objects. It is usually considered to be a late-developing high- level motor and cognitive skill involving the coordination of...
|Concordance of Handedness Between Teacher and Student Facilitates Learning Manual Skills
||Eighty-six left- and right-handed male and female adults received demonstrations of the manual actions involved in tying three different knots from either left- or right-handed female instructors. Learning was greatly facilitated by concordance of ha...
|Contribution of nesting experience to progesterone-induced incubation in ring doves (Streptopelia risoria).
||When a reproductively experienced dove is removed from visual isolation and placed in a breeding cage with an unfamiliar mate and a nest containing eggs, it takes about 5–7 days before it will exhibit incubation behavior. However, similarly experienc...
|Contributions of reproductive experience to observation maintained crop growth and incubation in male and female ring doves.
||Previous work has established that experienced male ring doves (Streptopelia risoria) can maintain prolactin-dependent crop growth and readiness to incubate by observing an incubating partner. We report that this is also true for female ring doves. T...
|Development of Infant Prehension Handedness: A Longitudinal Analysis During the 6- to 14-month Age Period.
||Handedness is a developmental phenomenon that becomes distinctively identifiable during infancy. Although infant hand-use preferences sometimes have been reported as unstable, other evidence demonstrates that infant hand-use preference for apprehendi...
|A developmental psychobiological approach to developmental neuropsychology.
||Although both developmental psychobiology and developmental neuropsychology examine the interface between biological and psychological processes, they differ in conceptual framework. This article argues for the incorporation into developmental neurop...
|The effect of certain task characteristics on performance on two neuropsychological tests of spatial abilites.
||Certain neuropsychological assessments of spatial ability assume that the processing of diagonality and nondiagonality of patterns is equivalent and that processing 2-D representations is equivalent to processing 3-D objects. The Stick Test and the L...
|Experience and progesterone in ring dove incubation.
||Doves were tested for progesterone-induced incubation after they had acquired previous experience with from one to five different phases of their initial breeding cycle. A sixth group had no previous breeding experience. Previous breeding experience ...
|Head orientation position during birth in neonatal period, and hand preference at 19 weeks.
||This study of lateral preferences of normal full-term infants found, as predicted, that infants who were delivered from a left occiput antenor or transverse birth position (head turned to the nght) exhibited a neonatal right supine head onentation an...
|A holistic developmental theory requires better research techniques.
||Research pragmatics, not a defective conceptual framework, supports modern biological reductionism. Conducting research to reveal the casual web underlying the multiple developmental pathways leading to any species-specific characteristic requires be...
|How supine postural preference of infants can contribute towards the development of handedness.
||During their first three months postpartum, infants manifest an asymmetrically lateralized head position preference, typically turned to the right. This head position preference elicits an asymmetrical tonic neck reflex, which places one hand in the ...
|Infant interest expressions as coordinative motor structures
||Two opposing facial actions, raised and knit (contracted} brows, hove been considered expressions of the unitary emotion of interest. We examined differential relationships between these brow actions and accompanying head, eye, arm, and other facial ...
|Infant "surprise" expressions as coordinative motor structures.
||This study found that the facial action of moderately or widely opening the mouth is accompanied by brow raising in infants, thus producing "surprise" expressions in non-surprise situations. Infants (age = 5 months and 7 months) were videotaped as th...
|Intermanual transfer of tactile discrimination.
||Little is known about infant tactile discrimination, even though most sensory and motor innervation of each and is ,restricted to the contralateral hemisphere....
|Intrauterine birth position predicts newborn supine head position preference.
||Intrauterine orientation of the fetus before delivery, as judged from head position during birth, was found to be a reliable precursor of the supine head position preference of the neonate. The neonate's head position affected the finger positions of...
|A lateral bias in the neuropsychological functioning of human infants
||Using my published and unpublished research, a description of the development and functional significance of infant hand-use preferences is presented. Although the character of the infant's handedness will vary with the development of manual skill, t...
|Maternal influences on infant hand-use during play with toys.
||Infant hand-use preferences are related to mother's, but not father's, handedness. Since infants match mother's hand-use during toy play, maternal handedness can affect infant hand-use. Twenty-eight mother— infant pairs (14 left-handed and 14 right-h...
|A meta-analysis of primate hand preference for reaching and other hand-use preferences.
||Humans, as do most vertebrate species studied, exhibit a limb preference for unimanual activities. However, two characteristics of the human limb preference are thought to distinguish it from that of other vertebrates: (a) The preference is the same ...
|Ontogenetic considerations in the phylogenetic history and adaptive significance of the bias in human handedness
||Previous amounts of nonhuman primate handedness have failed to find any population bias in the distribution of preference. Hence, it is generally believed that a bias in the distribution of handedness is restricted to humans. MacNeilage et al. conten...
|Ontogenetic constraints on the evolution of right-handedness.
||Ontogenetic factors constrain the evolution of species-typical traits. Because human infants are born “prematurely” relative to other pri- mates, the development of handedness during infancy can reveal impor- tant ontogenetic influences on handedness...
|Ontogeny of infant bimanual reaching during the first year.
||Handedness and pattern of coordination during bimanual reaching were assessed separately for six groups of infants, 7 to 12 months old. Infants reached bimanually for a transparent toy-filled box. On some presentations of the box a low barrier was pl...
|Rate and timing precision of motor coordination in Developmental Dyslexia.
||Learning to read builds on the speech processes of the child at many levels (Denckla, 1979; Mann, 1986), and language impairment is one of the most common behavioral correlates of developmental dyslexia (Doehring, Trites, Patel, & Fiedorowicz, 1981; ...
|Right handedness: A consequence of infant supine head orientation preference?
||Most newborn infants (65 percent) preferred to lie with their heads turned to the right, whereas 15 percent showed a distinct preference for the left. Orientation preference is maintained for at least 2 months and predicts preferential hand use in re...
|Sex Differences in neonatal state and lateralized head orientation.
||Sex differences in state and head orientation were examined 10 to 22 hours after birth for 50 healthy, full-term, normal, vaginally delivered neonates. None of the males had been circumcised at the time of testing. The procedure required videotaping ...
|What is embodied: "A-not-B error" or delayed-response learning?
||The procedures used to ensure reliable occurrences of the A- not-B error distort and miss essential features of Piaget’s original observa- tions. A model that meshes a mental event, highly restricted by testing pro- cedures, to the dynamics of bodily...
