The domain of supervisory processes and temporal organization of behaviour.
@article{Shallice1996TheDO, title={The domain of supervisory processes and temporal organization of behaviour.}, author={Tim Shallice and Paul W. Burgess}, journal={Philosophical transactions of the Royal Society of London. Series B, Biological sciences}, year={1996}, volume={351 1346}, pages={ 1405-11; discussion 1411-2 } }
The possibility that the supervisory system of Norman & Shallice (1986) can be fractionated into different subprocesses is discussed. It is argued that confronting a novel situation effectively requires a variety of different types of process. It is then argued that evidence of separability of different processes may be obtained by the observation of very low correlations across patients on more than one measure on each of which frontal patients show a performance deficit. Examples of this are…

The aim of this study was to re-examine the hypothesis of a link between frontal cortex and the Supervisory Attentional System (SAS) and although frontal patients were slower than control participants, the two groups did not differ in their ability to solve problems.

Modelling the Supervisory System and Frontal Dysfunction: An Architecturally Grounded Model of the Wisconsin Card Sorting Task
- PsychologyCogSci
- 2013
A model of the Wisconsin Card Sorting Test, a classical neuropsychological test frequently used to assess deficits in executive functioning, is presented and supports the association by Shallice et al. (2008) of the function of task-setting to left lateral prefrontal cortex, ofThe model is grounded in a cognitive architecture based on the Supervisory System theory of Norman and Shallice (1986) and evaluated against data from control subjects and several groups of neurological patients.
Order and Disorder in Everyday Action: the Roles of Contention Scheduling and Supervisory Attention
- PsychologyNeurocase
- 2002
The contention scheduling/supervisory attentional system approach to action selection is described and this account is used to structure a survey of current theories of the control of action on how such theories account for the types of error produced by some patients with frontal and/or left temporoparietal damage when attempting everyday tasks.
Further investigation of the Supervisory Attentional System in schizophrenia: Planning, inhibition, and rule abstraction
- Psychology, Medicine

Schizophrenic patients are impaired on all SAS functions, and the possible role of a general impairment (processing speed or cognitive resources) is discussed.
Age-related differences in supervisory attentional system functions.

The authors explored the effect of age on executive functions by using 3 tasks designed to assess specific executive processes (planning, inhibition, and abstraction of logical rules) that were also sensitive to frontal dysfunction.
Cognitive control of internally-guided behaviours
- Psychology
- 2006
The evidence in this thesis supports the suggestion that different executive processes are employed depending on the demand for internally- generated behaviour, and that the executive processes recruited for PM tasks reflect the demands made on internal control.

Control of Cognitive Processes

The progress achieved in fractionating, localizing, and modeling control functions, and in understanding the interaction between stimulus-driven and voluntary control, takes research on control in the mind/brain to a new level of sophistication.

A computer model is presented that performs 4 tasks sometimes impaired by frontal damage: motor sequencing, the Stroop task, the Wisconsin Card Sorting Test, and a context memory task, which shows how a single underlying type of damage could result in impairments on a variety of seemingly distinct tasks.

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.
