The specific question was how prenatal and/or postnatal experience with ethanol influences cardiac and behavioral responses to the odor of ethanol on postnatal day (PD) 16. In each of two experiments, pregnant rats were given ethanol or water on gestational days 17-20. Offspring were exposed on PD12 to one of three conditions: intragastric administration of(More)
The present study examined the relationship between the thermal environment and core body temperature in producing age-related patterns of ultrasonic vocalizations (USVs). Implanted telemetry devices allowed on-line measurement of core body temperature during an extended period of isolation and after maternal contact, both as a function of age and thermal(More)
Several studies have confirmed that diet selection patterns of adult rats are at least partially established as a result of early experiences with food-related stimuli present in the milk of a lactating female (e.g., Capretta & Rawls, 1974; Galef & Clark, 1972; Galef & Henderson 1972). The present experiments were designed to investigate whether preweanling(More)
Object knowledge refers to the understanding that all objects share certain properties. Various components of object knowledge (e.g., object occlusion, object causality) have been examined in human infants to determine its developmental origins. Viewpoint invariance--the understanding that an object viewed from different viewpoints is still the same(More)
An infantile predisposition to process quantity, over quality, of stimulation has been suggested in theories of cognitive and perceptual development, as well as for understanding ontogenetic differences in learning. In the present study, responsivity to stimulus intensity was assessed in preweanling and periadolescent rats by using magnitude of cardiac(More)
Previous animal models testing infantile reactivity to ethanol (EtOH) in maternal milk used EtOH doses that vastly exceeded levels actually encountered in a mildly or moderately intoxicated dam. The present study assessed whether 12- and 16-day-old rats are capable of detecting EtOH in milk at levels actually recorded in an intoxicated dam. Experiment 1(More)
Preweaning exposure to a foreign odor has been shown to alter later responding to that odor. Early experience with ethanol odor may alter not only responding to ethanol odor, but also intake of ethanol solutions. The present study tested the effects of exposure to ethanol odor prior to weaning on ethanol odor preference and ethanol consumption.(More)
Visual search, or the ability to locate a single target from a field of distractors, is used as a means of assessing the capacity of the visual system with regard to the detection of low-level stimulus dimensions such as color, line orientation, and other specific perceptual features and higher level characteristics such as three-dimensional (3-D)(More)
This investigation explored infants' ability to retrieve a memory for a simple 3D shape from a novel view following a 24-hr delay. Tests of memory for shape in infancy have typically used extremely short delay intervals between familiarization and test in examining the ability to equate between substantially different views of a 3D object. The current study(More)
The current study examined the role redundant amodal properties play in an operant learning task in 3-month-old human infants. Prior studies have suggested that the presence of redundant amodal information facilitates detection and discrimination of amodal properties and potentially functions to influence general learning processes such as associative(More)
