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

Different memory systems underlying acquisition of procedural and declarative knowledge.
TL;DR: It is shown that amnesic patients with marked disorders of learning and memory demonstrate a striking dissociation between the memory processes or memory systems that support the acquisition of cognitive skills and the processes or systems that mediate the Acquisition of new facts or other data-based knowledge.

Wisconsin card sorting test: a new global score, with Italian norms, and its relationship with the Weigl sorting test.
TL;DR: In this paper, a new measure of global efficiency (global score) is proposed as well as norms for some well known qualitative aspects of the performance, i.e., perseverative responses, failure to maintain the set and non-perseverative errors.

Instantaneous and causal connectivity in resting state brain networks derived from functional MRI data.
TL;DR: Findings indicate that regions whose activities are not synchronized interact via time-delayed causal influences, and segregation of different resting state networks is not clear cut but only by soft boundaries.

A critical review of habit learning and the Basal Ganglia.
Carol A. Seger,Brian J. Spiering +1 more
TL;DR: A multi-faceted approach to habit learning and its relationship to the basal ganglia is proposed, emphasizing the need for formal definitions that will provide directions for future research.
Journal ArticleDOI
Memory span on the Wechsler Scales.
TL;DR: The backward conditions of both Digit and Spatial Span did not appear more affected by risk factors such as aging or pathology than the forward scores, which runs contrary to the widespread notion that backward span provides differential sensitivity regarding working memory processing.

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.
