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.

Source memory in older adults: an encoding or retrieval problem?

TL;DR: In this article, the role of the frontal lobes in source memory, the extent to which they may be involved in the encoding and/or retrieval of source or context, and the conditions under which the source memory deficit in older people may be reduced or eliminated.

An interactive framework for examining prefrontal cognitive processes.

TL;DR: This article presented an interactive framework for understanding prefrontal cognitive processes that suggests that action selection results from a dynamic interaction among a person's working memory resources; the working memory demands of a task; and the strength of prepotent, but misleading, action alternatives.

Cognitive theories of autism

TL;DR: In this paper, the authors consider three theories of autism: The Theory of Mind Deficit, Executive Dysfunction and the Weak Central Coherence accounts, along with studies relevant to their emergence, their expansion, their limitations and their possible integration.

Planning and spatial working memory in Parkinson's disease.

TL;DR: Baseline measurement of the ability to execute a given plan of action, to generate low level strategies required for efficient searching, and spatial working memory capacity, established that the Parkinson's disease group was unimpaired on any of these measures.

Frontal lobe function, sleep loss and fragmented sleep.

TL;DR: The overall picture is one of a disparate range of impairment following sleep loss and sleep fragmentation, with executive impairment appears to be more closely related to hypoxaemic events than daytime sleepiness.

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

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.
