Resumo: The frequency of whistles and of diffuse vocalizations (chuts and chutters) of a single guinea-pig were recorded, in a domestic context, in the presence of food signaling stimuli. Whistles were elicited at a significantly higher rate by stimuli nearer the temporal the iminence of food. Diffuse vocalization increased, as whistles, with the occurrence of relevant stimuli, but only decreased when the animal was in contact with food. A further observation showed that vocalizations were emitted at a significantly higher rate in the presence of CS+ (a human caretaker who provided reinforcement) than in the presence of CS- (a human caretaker who did not). Results suggest that whistling and diffuse vocalizations are conditionable responses which varies in a non-monotonic way as a function of probability and temporal distance of reinforcement and which can be put under discrimination control using persons as stimuli.

Verificou-se, numa primeira observação, que a taxa de assobio aumentava significativamente à medida que surgiam estímulos mais próximos, temporalmente, da liberação do alimento, diminuindo contudo, drasticamente, quando os estímulos sinalizavam a iminência do alimento. A vocalização difusa mostrou o mesmo aumento que o assobio, porém não diminuia até que o alimento estivesse presente. Verificou-se, numa segunda observação, que as vocalizações eram emitidas numa taxa significativamente maior diante de um tratador que sempre fornecia alimento ao animal (CS+), que diante de outro que nunca o fazia (CS-). Os resultados sugerem que o assobio ao tratador e a vocalização difusa são respostas passíveis de condicionamento que variam de modo complexo em função da distância temporal do reforço e que podem ser submetidas a controle discriminativo usando-se pessoas como estímulos.Universidade Federal de Santa Catarina1994-01-01info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.ufsc.br/index.php/biotemas/article/view/2269110.5007/%xBiotemas; v. 7 n. 1/2 (1994); 79-932175-79250103-1643reponame:Biotemas (Online)instname:Universidade Federal de Santa Catarina (UFSC)instacron:UFSCporhttps://periodicos.ufsc.br/index.php/biotemas/article/view/22691/20660Copyright (c) 1994 Cesar Ades, Rosana Suemi Tokumaru, Beatriz de Mello Beisiegelinfo:eu-repo/semantics/openAccessAdes, CesarTokumaru, Rosana SuemiBeisiegel, Beatriz de Mello2012-01-24T14:11:50Zoai:periodicos.ufsc.br:article/22691Revistahttp://www.biotemas.ufsc.br/index.htmPUBhttps://periodicos.ufsc.br/index.php/biotemas/oai||carlospinto@ccb.ufsc.br2175-79250103-1643opendoar:2012-01-24T14:11:50Biotemas (Online) - Universidade Federal de Santa Catarina (UFSC)false
