Selective Breeding for an Infant Phenotype: Rat Pup Ultrasonic Vocalization (USV)
To examine processes underlying generational and developmental influences on anxiety, this laboratory produced two lines of (N:NIH strain) rats, selectively bred on the basis extreme rates ofExpand

Ultrasonic Vocalizations in Rat and Mouse Pups
The ultrasonic vocalization (USV), or isolation calling response, of infant rats and mice has been studied as a measure of the intensity of an aversive affective state and as an early communicativeExpand

Hypothermic vocalizations of rat pups (Rattus norvegicus) elicit and direct maternal search behavior.
Emissions of ultrasonic vocalizations (USVs) by rat pups (Rattus norvegicus) during hypothermia have consequences for recovery and warming. We investigated the effects on dam behavior of USVs emittedExpand

Psychosocial attributes and life experiences of disadvantaged minority mothers: age and ethnic variations.
This study examined age and ethnic differences in psychosocial factors among hispanic (n = 210) and black (n = 73) low-income mothers within 2 days after delivery. The sample included 45 black and 99Expand

Maternal behavior of SHR rats and its relationship to offspring blood pressures.
In Part I of this study maternal behavior of 15 spontaneously hypertensive (SHR) and 11 Wistar-Kyoto (WKY) rat mothers was recorded throughout the preweaning period. SHR mothers were observed: 1) inExpand

Five generations of selective breeding for ultrasonic vocalization (USV) responses in N:NIH strain rats.
This article reports on early results from an ongoing selective breeding study in which rats were selected for different rates of ultrasonic vocalization (USV) in response to isolation. Using theExpand

Selective breeding for infant rat separation-induced ultrasonic vocalizations: Developmental precursors of passive and active coping styles
Human depression and anxiety disorders show inherited biases across generations, as do antisocial disorders characterized by aggression. Each condition is preceded in children by behavioralExpand

Traumatized mothers can change their minds about their toddlers: Understanding how a novel use of videofeedback supports positive change of maternal attributions.
This study explored the use of a brief experimental intervention that integrates principles of infant-parent psychotherapy, videofeedback, controlled exposure to child distress in the context ofExpand

The ontogeny of maternal potentiation of the infant rats' isolation call.
Previous studies have shown that preweanling rat pups double or triple their rates of ultrasonic vocalization (USV) when isolated immediately after brief periods of maternal interactionExpand

Elevated plus-maze behavior in adult offspring of selectively bred rats
Animals sampled from the third generation (S3) of selective breeding of N:NIH strain rats based on ultrasonic vocalization (USV) rates in infancy (High, Low, and Random lines) were tested as adultsExpand
