Generally positive correlations between different ability tests provide the evidence for a factor of "general intelligence" or Spearman's g. Though a possible neural substrate for g is suggested by executive impairments following frontal lobe lesions, preserved IQs in some frontal patients have been taken as strong evidence against this interpretation. We show that such results depend on how g is measured. Patients with superior IQs on the most clinically popular test--the Wechsler Adult… Expand
Executive function and fluid intelligence after frontal lobe lesions
TLDR
Understanding of frontal lobe deficits may be clarified by separating reduced fluid intelligence, important in most or all tasks, from other more specific impairments and their associated regions of damage. Expand
The relationship between executive functions and fluid intelligence in schizophrenia
TLDR
It is proposed that this general factor reflects low fluid intelligence capacity, which accounts for much but not all cognitive impairment in this patient group, and may clarify the role of additional, more specific cognitive impairments in conditions such as schizophrenia. Expand
Correlational structure of ‘frontal’ tests and intelligence tests indicates two components with asymmetrical neurostructural correlates in old age
TLDR
It is suggested that age-related changes to DL and AC have the greatest cognitive impact and two biologically-meaningful components of variance in complex cognitive performance in older age are identified. Expand
A neural basis for general intelligence.
TLDR
The results suggest that "general intelligence" derives from a specific frontal system important in the control of diverse forms of behavior that is associated with selective recruitment of lateral frontal cortex in one or both hemisphere. Expand
The relationship between executive functions and fluid intelligence in Parkinson's disease
TLDR
Clinical assessment of neuropsychological deficits in PD should include tests of fluid intelligence, together with one or more specific tasks that allow for the assessment of residual frontal deficits associated with theory of mind and multitasking. Expand
Fluid intelligence loss linked to restricted regions of damage within frontal and parietal cortex
TLDR
Results suggest that coarse group comparisons cannot show the neural underpinnings of fluid intelligence tests, and deficits reflect the extent of damage to a restricted but complex brain circuit comprising specific regions within both frontal and posterior cortex. Expand
Is the Prefrontal Cortex Important For Fluid Intelligence? A Neuropsychological Study Using Matrix Reasoning
TLDR
The results failed to support the hypothesis that prefrontal damage would disproportionately impair fluid intelligence, and every prefrontal subgroup the authors studied had Matrix Reasoning scores that were indistinguishable from those of the brain-damaged comparison groups. Expand

Abstract Sternberg [Sternberg, R.J. (1985). Beyond IQ: a triarchic theory of human intelligence. New York: Cambridge Univ. Press.] has proposed that the general intelligence, or the g factor,Expand
Frontal Lobe Deficits after Head Injury: Unity and Diversity of Function
Deficits of “executive function” are commonly described following either focal frontal lobe lesions or the diffuse pathology of closed head injury. Here, correlational methods were used toExpand
Performance on tests of frontal lobe function reflect general intellectual ability
Recent studies have indicated that performance on tests of frontal lobe function are highly associated with general intellectual ability ( g). Some authors have even claimed that the availableExpand

Deficits in strategy application following frontal lobe damage in man.
TLDR
A quantitative investigation of the ability to carry out a variety of cognitive tasks was performed in patients who had sustained traumatic injuries which involved prefrontal structures, and it is argued that the problem arose from an inability to reactivate after a delay previously-generated intentions when they are not directly signalled by the stimulus situation. Expand
Intelligence and the Frontal Lobe: The Organization of Goal-Directed Behavior
TLDR
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
Severe disturbance of higher cognition after bilateral frontal lobe ablation
After bilateral ablation of orbital and lower mesial frontal cortices, a patient had profound changes of behavior that have remained stable for 8 years. Although he could not meet personal andExpand
Unilateral frontal lobectomy can produce strategy application disorder.
TLDR
A 51 year old right handed man showed a marked dissociation between his performance on standard neuropsychological tests and his everyday behaviour, and was impaired on a test of "strategy application" which requires goal articulation, plan specification, self-monitoring, and evaluation of outcomes.

The WAIS as a lateralizing and localizing diagnostic instrument: A study of 656 patients with unilateral cerebral lesions
TLDR
There was only a minor interaction with aetiology and there was no evidence of differential patterns of impairment associated with sex, and overall hemisphere differences and laterality index differences were obtained. Expand
Patterns of behavioral deficit associated with visual spatial neglect.
TLDR
Visual-spatial neglect as measured by an empirically derived response position preference score on the Raven Coloured Progressive Matrices was examined and position preference was significantly associated with homonymous visual field defects, constructional dyspraxia, and in patients with left cerebral lesions mixed or receptive aphasia.
