Effects of pretraining on conditioning-enhanced neophobia: Evidence for separable mechanisms of neophobia and aversion conditioning
Animal Learning & Behavior - Tập 14 - Trang 155-162 - 1986
In two experiments, rats (n = 228) received pretraining access to a distinctive novel flavor (saline) followed by aversion conditioning to a different novel conditioned stimulus (CS) (saccharin). Then the rats were tested for aversion to the CS (saccharin) or for conditioning-enhanced neophobia to a third novel flavor (casein hydrolysate). Pretraining access to a distinctive novel flavor that diff......
Overnight incubation of a partially conditioned eyeblink response in rabbits
Animal Learning & Behavior - Tập 3 - Trang 114-118 - 1975
Three experiments employing the rabbit eyelid conditioning paradigm examined the effect of a variable-duration rest period on the performance of a partially acquired CR. Conditioning performance improved as a direct monotonic function of the retention interval. Performance after a 24-h rest interval was substantially superior to that observed after a rest interval of several minutes. The third exp......
Socially transmitted food preferences can be used to study long-term memory in rats
Animal Learning & Behavior - Tập 31 - Trang 160-164 - 2003
Immediately after a recently fed rodentdemonstrator interacts with a conspecificobserver, the observer shows a substantially enhanced preference for whatever food its demonstrator ate. Here we show that (1) influence of a single, 30-min interaction with a demonstrator on an observer’s food preference lasts for at least 1 month, and (2) observers interacting on 2 successive days with a demonstrator......
Contextual generality of roosttime restlessness in captive American robins (Turdus migratorius)
Animal Learning & Behavior - Tập 9 - Trang 536-544 - 1981
A series of experiments with captive American robins examined factors affecting roosttime restlessness, that is, the burst of locomotor activity that appears at dusk and is thought to be a correlate of the communal roosting habit of this species. First, the restlessness occurred earlier on cloudy days than on sunny ones, suggesting the importance of illumination level in initiating the activity bu......
Discriminated and nondiscriminated avoidance conditioning of the rearing response in rats
Animal Learning & Behavior - Tập 5 - Trang 259-264 - 1977
Experiment 1 employed a shock box in which light beams ran at 10, 15, 20, or 25 cm above the floor level of the box. Four groups of nine rats each were trained to avoid shock by cutting the light beams or letting them pass by, which the animal accomplished by upward or downward change of its posture. Training employed a discriminated avoidance paradigm, 60 trials per day for 5 days, with a 5-sec C......
Potentiation of delayed matching with variable delays
Animal Learning & Behavior - Tập 13 - Trang 397-402 - 1985
In a delayed matching-to-sample procedure, pigeons chose a comparison stimulus that matched a sample stimulus presented earlier in the trial. The duration of the delay between sample-stimulus presentation and comparison-stimulus presentation was either varied over five values within each session or held constant within each session but varied over five blocks of sessions. Accuracy of matching to s......
Sexual imprinting: The stability of mate preference in Japanese quail (Coturnix coturnix japonica)
Animal Learning & Behavior - Tập 6 - Trang 363-365 - 1978
This study investigated the persistence of a mate preference that resulted from early social experience.Coturnix males that achieved an imprinting criterion of selecting an imprint object (an albino conspecific hen) in 8 of 10 trials were then given one of three intervening treatments. Subjects were housed for 10 days with only normal hens or albino and normal hens, or they were isolated for the t......
Temporal coding affects transfer of serial and simultaneous inhibitors
Animal Learning & Behavior - Tập 26 - Trang 336-350 - 1998
In three experiments with rats, the temporal relationships under which a conditioned inhibitor would transfer its inhibitory potential to an independently trained excitor in a summation test were investigated. Each experiment varied the temporal relationship between the inhibitor and the transfer excitor at test (serial or simultaneous) and, in addition, manipulated either the inhibitor-training e......
