Rat's time estimation under conditional discrimination procedure / Estimação de tempo em ratos submetidos a um procedimento de discriminação condicional
In a feature positive conditional discrimination procedure, a stimulus A is not followed by reinforcement when presented alone, but it is always followed by reinforcement when it is preceded by stimulus X. In the negative conditional discrimination procedure, a stimulus B is always followed by reinf...

| description | In a feature positive conditional discrimination procedure, a stimulus A is not followed by reinforcement when presented alone, but it is always followed by reinforcement when it is preceded by stimulus X. In the negative conditional discrimination procedure, a stimulus B is always followed by reinforcement when presented alone, but it is not followed by reinforcement when preceded by stimulus Y. This research examined if amodal information dealing with basic attributes, as duration, has the capability to acquire conditional properties in animals. Rats were submitted to positive or negative conditional discrimination procedures with stimulus X and Y, which were of the same physical modality, a light, but with different durations: X= 15 seg e Y= 5 seg (and A=5 seg, B=15 seg). The results showed that the animals discriminated excitatory and inhibitory properties related, respectively, to two different durations of the same stimulus, supporting the hypothesis that the duration, as an amodal stimulus component, can be associated to conditional properties, in rats. |
