TL;DR: In this article, the authors used different tests and procedures for testing out a theoretical model than they would for trying to predict the likelihood of successful return to work for a brain-injured patient.
Abstract: Assessments are carried out in order to answer questions. Consequently, the
nature of the question determines the assessment procedure. So we would use
different tests and procedures for testing out a theoretical model than we would
for trying to predict the likelihood of successful return to work for a brain-injured
patient. An example of the former is the work of Baddeley, Logie, Bressi, Della
Sala, and Spinnler (1986), who were trying to support or refute their hypothesis
that patients with Alzheimer’s disease had a deficit in the central executive
component of the working memory model (Baddeley & Hitch, 1974). An
example of the latter is Shallice and Burgess’s (1991) six elements test which
requires participants to plan and organise their activity over a 15-minute period
while following certain rules. Mayes (1986) discusses the different concerns of
researchers and clinicians with regard to memory assessments but his views are
equally relevant to assessments of executive functioning. When thinking about
frontal lobe or executive functioning clinicians are likely to be concerned with
answering such questions as:1. Does this person have cognitive impairments that are typically associated
with the Dysexecutive syndrome (DES)?

TL;DR: The extent to which the tests predicted the patients' everyday life problems was significantly predictive of at least some of the behavioral and cognitive deficits reported by patients' carers, supporting the conclusions that different tests measure different cognitive processes and that there may be limits to the fractionation of the executive system.
Abstract: Ninety-two mixed etiology neurological patients and 216 control participants were assessed on a range of neuropsychological tests, including 10 neuropsychological measures of executive function derived from 6 different tests. People who knew the patients well (relatives or carers) completed a questionnaire about the patient's dysexecutive problems in everyday life, and this paper reports the extent to which the tests predicted the patients' everyday life problems. All of the tests were significantly predictive of at least some of the behavioral and cognitive deficits reported by patients' carers. However, factor analysis of the patients' dysexecutive symptoms suggested a fractionation of the dysexecutive syndrome, with neuropsychological tests loading differentially on 3 underlying cognitive factors (Inhibition, Intentionality, and Executive Memory), supporting the conclusions that different tests measure different cognitive processes, and that there may be limits to the fractionation of the executive system.

TL;DR: The findings indicate that autobiographical and personal semantic memory show a consistent pattern of impairment, when a comparison is made which controls for the age of the memories and the subject's own past experience.
Abstract: This paper describes a new technique for assessing "autobiographical" and "personal semantic" memory in amnesic patients and healthy controls. It provides evidence of the reliability and validity of the procedure, and reports an age-related temporal gradient in amnesic patients. The results are considered in terms of the severity, the rate of onset, and the duration of the amnesia; and a preliminary analysis is given of the findings in different diagnostic groups. The findings indicate that autobiographical and personal semantic memory show a consistent pattern of impairment, when a comparison is made which controls for the age of the memories and the subject's own past experience.

TL;DR: The Rivermead Behavioral Inattention Test appears to be a valid and reliable test of visuospatial neglect and one which is likely to provide more information about everyday problems than existing measures of neglect.

TL;DR: The results suggest that it is important to recognize both the unity and diversity ofExecutive functions and that latent variable analysis is a useful approach to studying the organization and roles of executive functions.

TL;DR: The authors examines five common misunderstandings about case-study research and concludes with the Kuhnian insight that a scientific discipline without a large number of thoroughly executed case studies is a discipline without systematic production of exemplars.
Abstract: This article examines five common misunderstandings about case-study research: (1) Theoretical knowledge is more valuable than practical knowledge; (2) One cannot generalize from a single case, therefore the single case study cannot contribute to scientific development; (3) The case study is most useful for generating hypotheses, while other methods are more suitable for hypotheses testing and theory building; (4) The case study contains a bias toward verification; and (5) It is often difficult to summarize specific case studies. The article explains and corrects these misunderstandings one by one and concludes with the Kuhnian insight that a scientific discipline without a large number of thoroughly executed case studies is a discipline without systematic production of exemplars, and that a discipline without exemplars is an ineffective one. Social science may be strengthened by the execution of more good case studies.

TL;DR: The meaning of the terms "method" and "method bias" are explored and whether method biases influence all measures equally are examined, and the evidence of the effects that method biases have on individual measures and on the covariation between different constructs is reviewed.
Abstract: Despite the concern that has been expressed about potential method biases, and the pervasiveness of research settings with the potential to produce them, there is disagreement about whether they really are a problem for researchers in the behavioral sciences. Therefore, the purpose of this review is to explore the current state of knowledge about method biases. First, we explore the meaning of the terms “method” and “method bias” and then we examine whether method biases influence all measures equally. Next, we review the evidence of the effects that method biases have on individual measures and on the covariation between different constructs. Following this, we evaluate the procedural and statistical remedies that have been used to control method biases and provide recommendations for minimizing method bias.

TL;DR: The revised model differs from the old principally in focussing attention on the processes of integrating information, rather than on the isolation of the subsystems, which provides a better basis for tackling the more complex aspects of executive control in working memory.
