This article presents a recent study on sequential information processing in psychology. A result of a high rate of sequential information presentation is usually a decline in responding to individual bits of information, termed "psychological refractoriness." Psychological refractoriness is defined as a delay in a second reaction time relative to a first reaction time. The current study follows the above theory in attempting to determine if psychological refractoriness might be reduced or eliminated by removing the load on the response selection mechanism. Forced guidance was used to make the subject respond without delay during training. Such a procedure required no voluntary action by the subject but ensured that certain relevant muscles responded correctly. Forced guidance might be expected to alleviate the load on the response selection mechanism via involuntary training of correct muscular responses so that in subsequent testing, subjects could show shorter psychological refractoriness than those who had a comparable amount of normal voluntary practice.

    It has been claimed that bilingualism enhances inhibitory control, but the available evidence is equivocal. The authors evaluated several possible versions of the inhibition hypothesis by comparing monolinguals and bilinguals with regard to stop signal performance, inhibition of return, and the...

    In this paper we show that response facilitation in choice reaction tasks achieved by priming the (previously perceived) effect is based on stimulus-response associations rather than on response-effect associations. The reduced key-press response time is not accounted for by earlier established...

    The pathogenic effect of extreme events has been equated with their immediate stressfulness, and thereby with the biology of stress. This article extends this classical view to include, among other pathogenic factors the biological dimensions of learning, social interaction, territorial...
