摘要

The present research undertook to examined whether eye-blink conditioning of the nictitating membrane response (NM) in rabbit consists solely of motor learning or involves other extracerebellar control systems. The experimental procedures used a transfer design, to permit testing for retention of learning across different situations. The animals were first NM conditioned to a tone signal (CS) in the Pavlovian stock, where they typically show a discrete eye-blink response. Subsequently they were tested in a free environment on a continuous attention task to assess the range of their reactions to random presentations of the CS.rnThe results showed the presentation of the CS produced totally different behaviour in the free environment. The presentation of the CS produced: (a) a prolonged disruption of the constant attention task due to the presence of complex emotional reaction consisting of both retreating from and approaching to the sound source, (b) an absence of eye-blink responses. Control animals (that were not conditioned to the CS) were briefly distracted during the constant performance task (in the free environment), and also did not demonstrate any conditioned eye blink responses.rnThese findings provide strong evidence that Pavlovian learning involves the acquisition of a change in the meaning and emotional significance to the CS. This is expressed in differing situations by markedly different response patterns which unmasked a significant emotional component of the conditioning. These findings demonstrate that NM conditioning consists of more than a change in a discrete cerebellar oculomotor reflex. The clear emotional component to the conditioning indicates the involvement of extra-cerebellar control mechanisms, possibly the amygdala.
