Analysis of the process of encoding guidelines: a comparison of GLIF2 and GLIF3.

OBJECTIVES: This study aims to evaluate the use of a modified version of the Guideline Interchange Format (GLIF), GLIF3, in the translation of clinical practice guidelines into an electronically encoded form such that they may be shared among various clinical institutions and settings. METHODS: Based on theories and methods from cognitive science, the encoding of two clinical practice guidelines into two guideline modeling methods (GLIF3 and an earlier version, GLIF2) by two medical informaticians was captured on video and transcribed and annotated for analysis. RESULTS: Differing in both content and structure, the representations developed in GLIF3 were found to contain a greater level of representational detail and less ambiguity than those developed in GLIF2. CONCLUSIONS: The use of GLIF3 in the encoding of clinical guidelines offers significant improvements due to its greater formality as compared to earlier versions of GLIF.

More reliable data for diarrhoeal intervention programmes: rethinking on knowledge, attitude and practice studies.

The aim of this study was to propose an alternative approach to traditional knowledge, attitude and practice (KAP) studies to enhance the quality of data on which educational health programmes are based. The methodology proposed and illustrated involved a triangulation of approaches derived from linguistics, cognitive science, and medical laboratory sciences. Three diarrhoeal health talks (educational messages) as given to mothers in three primary-care facilities in Borno State (Northeast Nigeria) were subjected to a linguistics analysis. Relationships were then sought between the ontology of knowledge in the health talks as revealed by the text analysis and two other kinds of data, namely: (a) mothers' answers to a set of ecologically-sensitive reasoning questions that test how much relevant inferential knowledge the health talks allow for and (b) results of microbiological and biochemical analyses of salt-sugar rehydration solutions prepared by mothers participating in the study. The findings of the study show a relationship between contents/formatting of the health talks and the extent to which relevant inferential competence was supported or demonstrated by mothers. It was also evident that the laboratory analyses could be related either directly to the health talks or indirectly in terms of what the health talks need to emphasize on. The conclusion shows how the methodology proposed addresses shortcomings of traditional KAP studies in respect of the gap between health knowledge and practice.

A new method for matching a document to potential users' information needs.

This paper explores approach to finding out how the information needs that a document can address can be captured. This is important in order to improve indexing strategies applied to document collections. We propose and implemented a cognitive science approach, the "jeopardy game" method of evaluation combined with "think aloud" analysis. The results of the demonstration study are presented and discussed. Some possible improvements to the method for matching a document to potential users' information needs are identified.

Virtual reality training improves students' knowledge structures of medical concepts.

Virtual environments can provide training that is difficult to achieve under normal circumstances. Medical students can work on high-risk cases in a realistic, time-critical environment, where students practice skills in a cognitively demanding and emotionally compelling situation. Research from cognitive science has shown that as students acquire domain expertise, their semantic organization of core domain concepts become more similar to those of an expert's. In the current study, we hypothesized that students' knowledge structures would become more expert-like as a result of their diagnosing and treating a patient experiencing a hematoma within a virtual environment. Forty-eight medical students diagnosed and treated a hematoma case within a fully immersed virtual environment. Student's semantic organization of 25 case-related concepts was assessed prior to and after training. Students' knowledge structures became more integrated and similar to an expert knowledge structure of the concepts as a result of the learning experience. The methods used here for eliciting, representing, and evaluating knowledge structures offer a sensitive and objective means for evaluating student learning in virtual environments and medical simulations.

[Risk discourse in Hormone Replacement Therapy].

The medical world has used Hormone Replacement Therapy (HRT) on menopausal women for over 70 years, but controversy surrounding the treatment remains. Findings reported by the NIH, U.S.A. in July 2002 indicated that HRT might cause cardiovascular and cancer risks, and resulted in serious concern among menopausal women using HRT in Taiwan. One after the other, members of the medical profession in Taiwan have argued that the medicine used in the research was different (from that used in Taiwan) and that the constitutions of western women are different from those of Taiwanese women, attempting to limit the negative impact of this research. HRT is one of the most widely used, but also one of the most controversial of medical technologies. The technico-scientific and sociocultural perspectives are two major approaches to the conceptualization of risk in relation to technology. Based on cognitive science, the technico-scientific discourse of risk emphasizes human forecasting of harmful events and scientific measures for preventing risk. The sociocultural perspective emphasizes that the risk is socially constructed and applies to control deviance. In addition, surveillance and regulated measures are applied to high-risk populations, as normalizing technology with moral implications. This paper suggests that health care professionals examine how HRT users interpret the meanings of risk. Reflection on the process and criteria for identifying high-risk populations is also suggested. Partnership with and empowerment of HRT users is advocated in preference to the use of regulating and normalizing measures.

Individual differences and attentional varieties.

With its own functional anatomy, circuitry and cellular structure, attention can be viewed as an organ system. This conceptualization reframes many problems in cognitive science and permits important insights into neurological and psychiatric disorders of both children and adults. Specifically, construing attention as an organ system helps to describe the evolutionary and developmental aspects of volitional control, thus paving the road towards a better appreciation of how such factors as genetics and culture influence control systems. The efficiency of the attention networks differs between people. However, these individual differences may elucidate variation in intelligence as well as the ability to regulate affect.

Theories of creativity.

Creativity is an important aspect of our lives. The term distinguishes mediocre achievements from those of excellence. Creativity is a manifestation of thought processes. To better understand these processes this article reviews five current theories of creativity from psychoanalytic and cognitive science approaches.

Influence of affective words on lexical decision task in major depression.

In cognitive science, lexical decision task is used to investigate visual word recognition and lexical access. The issue of whether or not individuals who are depressed differ in their access to affectively laden words and specifically to words that have negative affect was examined. Based on some aspects of the Resource Allocation Model (Ellis), it was postulated that patients suffering from depression take more time to recognize items from an affective-loaded list. In order to compare their behavior in a lexical decision task, patients suffering from depression and healthy controls were studied. We hoped to find an interaction between the mood state of subjects and the categories (affective or neutral) of words. Two groups of right-handed adults served as subjects in our experiment. The first group consisted of 11 patients suffering from depression (mean age: 40.2; sd: 6.8). All of this group met the DSM-III-R and the Research Diagnostic Criteria for major depressive disorder. Severity of their disease was rated using the 24-item Hamilton Depressive Rating Scale. All patients suffering from depression were without psychotropic medication. The control group was composed of 24 subjects (mean age: 32.7; sd: 7.9). A depressive word-list and a neutral word-list were built and a computer was used for the lexical-decision task. A longer reaction time to detect the non-word stimuli (F1,33 = 11.19, p < 0.01) was observed with the patients by comparison to the normal subjects. In the analysis of the word stimuli, a group by list interaction (F1,33 = 7.18, p < 0.01) was found.(ABSTRACT TRUNCATED AT 250 WORDS)

On the drive-rootedness of psychoanalytic ego psychology.

This paper attempts, hypothetico-deductively, to conceptualise psychoanalysis on the level of fundamental theory. I begin by exploring the relevance for psychoanalytic theory of recent developments in the brain and cognitive sciences. Their site of articulation is identified as the concept of consciousness. I proceed to develop a conceptual integration of consciousness into psychoanalytic drive theory. This reveals the wish as the original psychical entity, with a self-process imbricated in its structure. Narcissism in shown to be sexually grounded, vitally constitutive, and intrinsically aggressive. It becomes possible, using the neighbouring sciences as well, to work out a theory of the origin of the secondary process and early ego formation. My approach provides a view of mental development in which identification and repression represent two aspects of a unitary activity that structures the mind. This allows the unconscious and consciousness to be brought into dialectical relation. Implications follow for the 'activity of the repressed' and the theory of paranoia.

Why Johnny can't reengineer health care processes with information technology.

Many educational institutions are developing curricula that integrate computer and business knowledge and skills concerning a specific industry, such as banking or health care. We have developed a curriculum that emphasizes, equally, medical, computer, and business management concepts. Along the way we confronted a formidable obstacle, namely the domain specificity of the reference disciplines. Knowledge within each domain is sufficiently different from other domains that it reduces the leverage of building on preexisting knowledge and skills. We review this problem from the point of view of cognitive science (in particular, knowledge representation and machine learning) to suggest strategies for coping with incommensurate domain ontologies. These strategies include reflective judgment, implicit learning, abstraction, generalization, analogy, multiple inheritance, project-orientation, selectivity, goal- and failure-driven learning, and case- and story-based learning.

Adolescent self-concept among Han, Mongolian, and Korean Chinese.

Studies of self-concept have suffered from a lack of both a solid theoretical base and a clear definition of the term. It is not clear whether self-concept is a construct from the cognitive sciences, an active part of personality or of the ego and unconscious, or a physiological process as indicated from neurological research. Nor is it clear whether the psychological construct of self is related to other concepts, such as personal identity, self-esteem, and the ego, as sometimes these refer to the whole person or a structure or element within a person. What is evident is that the majority of researchers continue to assume that self-concept, however defined in theory, is primarily governed by environmental determinants despite abundant evidence from the neurosciences of the strong influence of its genetic heritability. This study assumed a genetic hypothesis, that self-concept is developmental and that adolescent perception of personal, relational, and academic self-identity occurs uniformly across cultures and environmental circumstances. Data were collected using a validated survey instrument, translated into Chinese, from majority and minority adolescents in the People's Republic of China. High similarity was found between the majority and minority adolescents, suggesting developmental propensities in the formation of self-concept.

Weaving the fabric of social interaction: articulating developmental psychology and cognitive neuroscience in the domain of motor cognition.

In this article, we bring together recent findings from developmental science and cognitive neuroscience to argue that perception-action coupling constitutes the fundamental mechanism of motor cognition. A variety of empirical evidence suggests that observed and executed actions are coded in a common cognitive and neural framework, enabling individuals to construct shared representations of self and other actions. We review work to suggest that such shared representations support action anticipation, organization, and imitation. These processes, along with additional computational mechanisms for determining a sense of agency and behavioral regulation, form the fabric of socialinteraction. In addition, humans possess the capacity to move beyond these basic aspects of action analysis to interpret behavior at a deeper level, an ability that may be outside the scope of the mirror system. Understanding the nature of shared representations from the vantage point of developmental and cognitive science and neuroscience has the potential to inform a range of motor and social processes. This perspective also elucidates intriguing new directions and research questions and generates specific hypotheses regarding the impact of early disorders (e.g., developmental movement disorders) on subsequent action processing.

The science of animal cognition: past, present, and future.

The field of animal cognition is strongly rooted in the philosophy of mind and in the theory of evolution. Despite these strong roots, work during the most famous and active period in the history of our science-the 1930s, 1940s, and 1950s-may have diverted us from the very questions that were of greatest initial interest to the comparative analysis of learning and behavior. Subsequently, the field has been in steady decline despite its increasing breadth and sophistication. Renewal of the field of animal cognition may require a return to the original questions of animal communication and intelligence using the most advanced tools of modern psychological science. Reclaiming center stage in contemporary psychology will be difficult; planning that effort with a host of strategies should enhance the chances of success.

A primer on aspects of cognition for medical informatics.

As a multidisciplinary field, medical informatics draws on a range of disciplines, such as computer science, information science, and the social and cognitive sciences. The cognitive sciences can provide important insights into the nature of the processes involved in human- computer interaction and help improve the design of medical information systems by providing insight into the roles that knowledge, memory, and strategies play in a variety of cognitive activities. In this paper, the authors survey literature on aspects of medical cognition and provide a set of claims that they consider to be important in medical informatics.
