His research interests include behavioural analytic approaches to skills-based learning and reflection as a natural phenomenon. Current conceptualisations of reflection have…

Visual cues from the speaker's face, such as the discriminable mouth movements used to produce speech sounds, improve discrimination of these sounds by adults. The speaker's face, however, provides more information than just the mouth movements used to produce speech--it also provides a visual indexical cue of the identity of the speaker. The…

Syllable frequency has been shown to facilitate production in some languages but has yielded inconsistent results in English and has never been examined in older adults. Tip-of-the-tongue (TOT) states represent a unique type of production failure where the phonology of a word is unable to be retrieved, suggesting that the frequency of phonological…

The research presented in this dissertation examined changes in brain activity associated with learning, forgetting and using a second language. The first experiment investigated the changes that occur when novice adult second language learners acquire and forget second language words. Event-related brain potentials were measured while native…

In the last two decades, La Heij and colleagues have presented accounts of a number of context effects in Stroop-like word-production tasks. Roelofs (2007 this issue) criticises various aspects of our proposals, ranging from the number of processing stages assumed to details of simulation results. In this reply we first argue that we do not…
