Reading and recognising acronyms: Insights from behavioural, electrophysiological and neuropsychological investigations. / David Ross Playfoot

Swansea University Author: David Ross Playfoot

Abstract

This thesis examined the processes involved in reading and recognising acronyms (e.g. BBC, HIV, NATO). Normative values for frequency, age of acquisition, imageability, length, bigram and trigram frequency and orthographic neighbourhood size have been collected, and the influence of these factors on...
