Olfactory-guided orientation in neonatal rats is enhanced by a conditioned change in behavioral state.
In Experiment 1, 3-6-day-old rats were simultaneously exposed to an unfamiliar odor which they will normally avoid (orange extract) and the odor of maternal saliva, or to either orange alone or… Expand
Reinforcers in infancy: classical conditioning using stroking or intra-oral infusions of milk as UCS.
Six-day-old rats received 20 forward pairings of an odor-conditioned stimulus (CS) with one of two unconditioned stimuli (UCS); 1) intra-oral milk infusions or 2) stroking with a sable-hair brush.… Expand

Infant rat pups were exposed to a novel odor (orange or cedar) while they received tactile stimulation (stroking of the body) or were presented with odor or stroking alone. The effects of these… Expand

ABSTRACT Late-early Paleocene (Torrejonian) salamanders and lizards from the Gidley and Silberling quarries comprise a rather small but relatively diverse assemblage. Salamanders include the… Expand
CHROMOSOMAL, GENIC, AND MORPHOLOGIC VARIATION IN THE AGILE KANGAROO RAT, DIPODOMYS AGILIS (RODENTIA: HETEROMYIDAE)
Chromosomal, genic, and morphologic variation was examined among populations of Dipodomys agilis from southern California and Baja California, including populations previ- ously recognized as D.… Expand
The role of intraoral and gastrointestinal cues in the control of sucking and milk consumption in rat pups.
Nutritive deprivation, suckling deprivation, gastronintestinal fill, and milk availability contribute to the control of sucking (as measured by jaw-muscle electromyograph) and ingestion of milk… Expand
Short- and long-term effects of various milk-delivery contingencies on sucking and nipple attachment in rat pups.
Varied milk delivery contingencies differentially affect sucking in rat pups as measured by jaw-muscle electromyographic activity. In Experiment I we found that 11-13-day-old pups sucked more… Expand
