This chapter is going to address some issues about information science (IS) or library and information science (LIS) as an academic field. The main purpose is to set up a number of interrelated dimensions or levels, which are perhaps often taken for granted, but are here considered to be in need for systematic consideration. Each level is discussed in a separate section: 2. Is LIS an academic discipline? 3. What are the various names given to the field? How do they (...) reflect underlying conceptions of the field? 4. What is the aim of LIS? What are we trying to achieve? 5. What are the core concepts of information science? 6. What are the most important metatheories and research traditions in the LIS? (shrink)

The long-term persistence of neurotic symptoms, such as anxiety, poses difficult problems for any psychological theory. An attempt is made to revive the Watson-Mowrer conditioning theory and to avoid the many criticisms directed against it in the past. It is suggested that recent research has produced changes in learning theory that can be used to render this possible. In the first place, the doctrine of equipotentiality has been shown to be wrong, and some such concept as Seligman's “preparedness” is required, (...) that is the notion that certain CS are biologically prepared to be more readily connected with anxiety responses than others. In the second place, the law of extinction has to be amended, and the law of incubation or enhancement added, according to which the exposure of the CS-only may, under certain specified conditions, have the effect of increasing the strength of the CR, rather than reducing it. The major conditions favouring incubation are Pavlovian B conditioning, that is a type of conditioning in which the CR is a drive; a strong UCS, and short exposure of the CS-only. (shrink)

This paper considers the concept of freedom in behavioural terms, defining it in relation to freedom of action. This notion is applied to psychiatric abnormalities, and it is suggested that this new way of looking at the problem may go some way to surmount the philosophical difficulties normally attaching to the notion of freedom.

Attentional control theory (ACT) was proposed to account for trait anxiety’s effects on cognitive performance. According to ACT, impaired processing efficiency in high anxiety is mediated through inefficient executive processes that are needed for effective attentional control. Here we review the central assumptions and predictions of ACT within the context of more recent empirical evidence from neuroimaging studies. We then attempt to provide an account of ACT within a framework of the relevant cognitive processes and their associated neural mechanisms and (...) networks, particularly the fronto-parietal, cingular-opercula, and default mode networks. Future research directions, including whether a neuroscience-informed model of ACT can provide a platform for novel neurocognitive intervention for anxiety, are also discussed. (shrink)

This article is the first in a trilogy about the concept “science”. Section 1 considers the historical development of the meaning of the term science and shows its close relation to the terms “knowl­edge” and “philosophy”. Section 2 presents four historic phases in the basic conceptualizations of science science as representing absolute certain of knowl­edge based on deductive proof; science as representing absolute certain of knowl­edge based on “the scientific method”; science as representing fallible knowl­edge based on “the scientific method”; (...) science without a belief in “the scientific method” as constitutive, hence the question about the nature of science becomes dramatic. Section 3 presents four basic understandings of the scientific method: Rationalism, which gives priority to a priori thinking; empiricism, which gives priority to the collection, description, and processing of data in a neutral way; historicism, which gives priority to the interpretation of data in the light of “paradigm” and pragmatism, which emphasizes the analysis of the purposes, consequences, and the interests of knowl­edge. The second article in the trilogy focus on different fields studying science, while the final article presets further developments in the concept of science and the general conclusion. Overall, the trilogy illuminates the most important tensions in different conceptualizations of science and argues for the role of information science and knowl­edge organization in the study of science and suggests how “science” should be understood as an object of research in these fields.

Originally published in 1973 the editors of this book collected together those studies which had been considered at the time to yield the best evidence in support of Freudian theory, and found on close examination that they failed to provide any such proof. Each paper is printed in full and is followed by a critical discussion which raises questions of statistical treatment, sufficiency of controls and alternative interpretations. The particular usefulness of this format is that it allows readers to form (...) their own opinions while providing helpful suggestions and guidelines on how to approach experimental studies with a critical mind.
