The major question of interest in the present investigation was whether or not a UCS is more effectively represented in STM when its occurrence is relatively surprising as opposed to expected. (Author)

The results of this study suggested that size change may contribute to the forgetting of events occurring late in development, but that neurological immaturity may underly the forgetting of earlier events. (Editor/RK)

The research reported here was directed at evaluating whether or not the effectiveness of a Pavlovian unconditioned stimulus (US) in promoting associative learning is reduced if the US is shortly preceded by another occurrence of the same US. (Author)

Repeated, isolated presentations of a stimulus typically reduce the subsequent ability of that cue to become an effective conditioned stimulus. This phenomenon is known as the latent inhibition effect. Four experiments investigate this effect. (Editor/RK)
