TLDR
An information-processing model is outlined that predicts that performance on non-routine tasks can be impaired independently of performance on routine tasks, related to views on frontal lobe functions, particularly those of Luria.Abstract:
An information-processing model is outlined that predicts that performance on non-routine tasks can be impaired independently of performance on routine tasks. The model is related to views on frontal lobe functions, particularly those of Luria. Two methods of obtaining more rigorous tests of the model are discussed. One makes use of ideas from artificial intelligence to derive a task heavily loaded on planning abilities. A group of patients with left anterior lesions has a specific deficit on the task. Subsidiary investigations support the inference that this is a planning impairment.read more

The effect of goal-subgoal conflict on planning ability after frontal- and temporal-lobe lesions in humans
TL;DR: The left frontal lesion and right temporal lobectomy groups were significantly impaired on problems with goal-subgoal conflicts, whereas the right temporal group showed a more general deficit on later five-move problems.

Prediction of psychosocial recovery after head injury with cognitive tests and neurobehavioral ratings.
TL;DR: The results supported the hypothesis that tests of flexibility and programming rather than tests of cognitive skills predict psychosocial recovery after closed-head injury, and cognitive flexibility and mental programming are very important psychological prerequisites of social recovery after CHI.

The serotonin 5-HT2A receptors antagonist M100907 prevents impairment in attentional performance by NMDA receptor blockade in the rat prefrontal cortex.
TL;DR: Evidence that the prefronto-cortical glutamate NMDA system may make an important contribution to the control of attention and executive functions is provided and it is indicated that 5-HT2A receptors may serve to optimize attentional selectivity and improve some aspects of executive control.

Frontal Lobe Functioning in Man: The Riddle Revisited
TL;DR: Neither the results of the present study nor the findings of other researchers argue for the abandonment of the concept of "executive" functioning, mediated by the functioning of the frontal lobes, in favor of a variant of fractionation.

Neuropsychiatric effects of guanfacine in children with mild tourette syndrome: a pilot study.
TL;DR: At a moderate dose and short-term treatment duration, guanfacine did not provide significant neuropsychiatric benefits in this group of children with mild TS.

Human Problem Solving
TL;DR: The aim of the book is to advance the understanding of how humans think by putting forth a theory of human problem solving, along with a body of empirical evidence that permits assessment of the theory.

Controlled and automatic human information processing: II. Perceptual learning, automatic attending and a general theory.
TL;DR: Tested the 2-process theory of detection, search, and attention presented by the current authors (1977) in a series of experiments and demonstrated the qualitative difference between 2 modes of information processing: automatic detection and controlled search.

Higher cortical functions in man
TL;DR: Among the authors' patients was a bookkeeper with a severe form of sensory aphasia who could still draw up the annual balance sheet in spite of severe disturbances of speech and although he was unable to remember the names of his subordinates and used to refer to them incorrectly.

Attention to action: willed and automatic control of behavior
Donald A. Norman,Tim Shallice +1 more
TL;DR: This chapter proposes a theoretical framework structured around the notion of a set of active schemas, organized according to the particular action sequences of which they are a part, awaiting the appropriate set of conditions so that they can become selected to control action.
