摘要：Abstract According to dominant biological behavior theory laboratorial behaviors are over determined; this principle states that we must be aware of preparedness evolutionary. In this study, the effect of tone, movement and light interference on selective association behavior of laboratorial rats during the day and night has been studied. Subjects of this study include 4 white laboratory rats which have randomly chosen and divided into experimental and control groups. Then the rats were manipulated in two groups during the day and night with shock, avoidance program and compound antecedent stimuli (light, tone and movement). The subjects of both groups were manipulated concomitancy of compound shock stimulus was done next in the antecedent stimulus as a conditional to control the avidness answer was chosen to be analyzed. Different parts of the antecedent compound were presented to the rats in two groups during the day and night. The results show that there is a significant difference between the frequencies of selective associations during the day and night. The result cast doubt on this principle that all stimuli and responses are equally conditionable and any reinforcer could be paired with any behaviour so that learning would occur with equal strength and rapidly
