Shooting stars: A review and development of the multiplicative transform K* in explanations of temporal reference memory in SET.

    Research output: Chapter in Book/Report/Conference proceedingConference contribution


    A common way of positing scalar variance in the SET information-processing model of timing (Gibbon & Church, 1982/1992; Meck, 1983) is in the form of a multiplicative transform (K*). This transform operates when the contents of the accumulator/working memory are transferred to reference memory, scalar variance being produced upon multiple presentations of the standard. A brief review of this concept and research findings that sheds new light on its validity and the general nature of temporal reference memory is presented. There were two main strands to the empirical studies presented: the first examined the effect of manipulating the number of presentations of the standard tone in a modified temporal generalization task. Some conceptualisations of the K* transform predict an increase in temporal acuity with increased number of presentations. In fact,results suggested that the effect of multiple presentations of a temporal generalization standard was small or non-existent, over and above the effect of presenting a single example of the standard. The second strand of research examined the encoding of temporal reference memory. Does the formation of a reference memory require just encoding or is utilisation of that memory also necessary? The capacity of temporal reference memory was also examined by manipulating the number of standards to been coded. This was achieved by the use of a modified version of the temporal generalization procedure called double temporal generalization.
