Subjects were exposed to pictures of self and others (e.g., friend, stranger, and famous people) to determine if there was an advantage in reaction time and accuracy in identifying the self. It was found that upright and inverted self-faces were identified more rapidly than non-self faces when subjects responded with their left hand, which in other tasks(More)
A small drop of either citric acid, HCl, or NaCl, judged to be approximately equal in magnitude, was applied to two papillae for a fixed duration (15 sec). The stimulus was then reapplied to the same papillae and judged for magnitude of sensation ("self-adaptation" design). NaCl was about 50% less intense after 15 sec of prior exposure whereas citric acid(More)
Cholecystokinin-octapeptide (CCK-8) was injected intraperitoneally into rats to see if it could cause them to eat kaolin (clay)--a pica behavior which has been shown to indicate gastric distress. In the first study, a single large dose of CCK-8 (20 micrograms/kg) failed to produce pica. In the second study, 4 smaller doses of CCK-8 (8 micrograms/kg), 30 min(More)
Sodium deficient, adrenalectomized rats and nondeficient control rats were offered, for 20 min, either a mixture of 0.15 M sodium chloride and 0.3 M sucrose, or a 0.3 M sucrose solution. The sodium deficient rats drank about 3 times more of the mixture than of the sucrose alone. Nondeficient control animals showed no differential preference for the mixture(More)
Sodium deficient, adrenalectomized rats and nondeficient control rats were offered, for 20 min, a mixture of 0.1 M NaCl and 0.02 N HCl. The sodium deficient rats drank substantial amounts whereas control animals were essentially indifferent to the mixture. Further tests on the sodium deficient rats with a stronger NaCl concentration in the mixture did not(More)
Infants five to thirty months old were observed for one week on entering a day care program, and again at the end of one month. Frequency of behaviors reflecting social and emotional adjustment were recorded. There was significant decreases in frequency of crying, sitting alone, and interacting with adults, while interactions with other children increased(More)
