The ecological validity of tests of executive function.
The extent to which the tests predicted the patients' everyday life problems was significantly predictive of at least some of the behavioral and cognitive deficits reported by patients' carers, supporting the conclusions that different tests measure different cognitive processes and that there may be limits to the fractionation of the executive system.

The Children's Test of Nonword Repetition: a test of phonological working memory.
Findings from the Children's Test of Nonword Repetition are shown to be consistently higher and more specific than those obtained between language skills and another simple verbal task with a significant phonological memory component, auditory digit span. Expand
Phonological memory and vocabulary development during the early school years: A longitudinal study.
The nature of the developmental association between phonological memory and vocabulary knowledge was explored in a longitudinal study. At each of 4 waves (at ages 4, 5, 6, and 8 yrs), measures ofExpand
Intelligence and the Frontal Lobe: The Organization of Goal-Directed Behavior
It is suggested that g is largely a reflection of the control functions of the frontal lobe, and behavior in any task is structured by a set of action constraints or requirements, derived in part from verbal instructions and specified at multiple levels of abstraction. Expand
Random Generation and the Executive Control of Working Memory
It is predicted that a task involving repeated switching of categories will interfere with generation, despite being predictable and having a low memory load, and the implications for the analysis of executive processes are discussed. Expand
Reducing everyday memory and planning problems by means of a paging system: a randomised control crossover study
This particular paging system significantly reduces everyday failures of memory and planning in people with brain injury. Expand
Fluid intelligence after frontal lobe lesions
The data suggest that g may in large part be a reflection of frontal functions, and it is fluid intelligence that is most closely related to Spearman's g. Expand
