- Load theory of selective attention and cognitive control
Department of Psychology, University College London, London, United Kingdom
J Exp Psychol Gen 133:339-54. 2004

- Neuronal correlates of parametric working memory in the prefrontal cortex
Instituto de Fisiologia Celular, Universidad Nacional Autonoma de Mexico, Mexico DF
Nature 399:470-3. 1999
..Thus we predict that other behavioural tasks that require ordinal comparisons between scalar analogue stimuli would give rise to monotonic responses similar to those reported here...
