Personality characteristics of hospice volunteers as measured by Myers-Briggs Type Indicator.

A sample of hospice volunteers (n = 99) was administered the Myers-Briggs Type Indicator (Myers & McCaulley, 1985). Frequencies of types observed were compared to population sample (n = 1,105) frequencies. Results indicated that, as a whole, hospice volunteers preferred extraversion over introversion, intuition over sensing, and feeling over thinking. Analysis of four-and two-letter preference combinations also yielded statistically significant differences. Most notably, the sensing-intuitive function appeared pivotal in determining of hospice volunteering. Suggestions are offered as to why the sensing-intuition function appeared central to hospice volunteering. Results appeared consistent with Jungian personality theory.

Non-formal learning and tacit knowledge in professional work.

BACKGROUND: This paper explores the conceptual and methodological problems arising from several empirical investigations of professional education and learning in the workplace. AIMS: 1. To clarify the multiple meanings accorded to terms such as 'non-formal learning', 'implicit learning' and 'tacit knowledge', their theoretical assumptions and the range of phenomena to which they refer. 2. To discuss their implications for professional practice. METHOD: A largely theoretical analysis of issues and phenomena arising from empirical investigations. ANALYSIS: The author's typology of non-formal learning distinguishes between implicit learning, reactive on-the-spot learning and deliberative learning. The significance of the last is commonly overemphasized. The problematic nature of tacit knowledge is discussed with respect to both detecting it and representing it. Three types of tacit knowledge are discussed: tacit understanding of people and situations, routinized actions and the tacit rules that underpin intuitive decision-making. They come together when professional performance involves sequences of routinized action punctuated by rapid intuitive decisions based on tacit understanding of the situation. Four types of process are involved--reading the situation, making decisions, overt activity and metacognition--and three modes of cognition--intuitive, analytic and deliberative. The balance between these modes depends on time, experience and complexity. Where rapid action dominates, periods of deliberation are needed to maintain critical control. Finally the role of both formal and informal social knowledge is discussed; and it is argued that situated learning often leads not to local conformity but to greater individual variation as people's careers take them through a series of different contexts. This abstract necessarily simplifies a more complex analysis in the paper itself.

[Influence of personality and learning styles in the choice of medical specialty].

BACKGROUND: Several studies indicate that doctors who work in the same area of the medical profession tend to behave somehow similarly. Thus, it has been suggested that personality relates to the medical specialty choice. However, it is not known whether people self-select into the medical specialties according to their personality or the professional practice in a particular field influences their behavior. AIM: To explore the possible association between the graduate's personality features and learning styles and their chosen specialty. SUBJECTS AND METHODS: The psychological preferences and learning styles of 65 students of the 2001-graduating cohort of the Pontificia Universidad Católica de Chile School of Medicine were evaluated with the Myers Briggs Type Indicator and the Kolb Learning Style Inventory, respectively. These variables were correlated with the information of their specialty choice or occupation two years after graduation. RESULTS: Graduates distributed unevenly in different areas of the medical profession. Surgical specialties concentrated a larger proportion of extraverted, intuitive and structured doctors, whereas in Pediatrics and Internal Medicine predominated intuitive and people-oriented MD's. Primary Care concentrated individuals with introverted, intuitive and flexible attitudes. Convergent learners (interested in problem-solving) preferred Surgery and Primary Care whereas Assimilator learners (abstract-reflexive) chose more frequently Internal Medicine, Pediatrics and Psychiatry. CONCLUSIONS: According to their personality and learning style, graduates tend to self-select into different medical specialties. This information may help medical graduates to guide their specialty choice process, and medical educators to develop learning experiences that take into account the individual differences of their residents.

Lying and deceiving--moral choice in public and private life.

Suppose that there are good or morally defensible reasons for not responding truthfully to a question or request for information. Is a lie or a deception better as a means to avoid telling the truth? There are many situations in public and private life in which the answer to this question would serve as a useful moral guide, for instance, clinical situations involving dying patients, educational situations, involving young children and personal situations involving close friends. Intuitively, we feel that there is a moral asymmetry in favor of deceiving over lying. However, doubts have been cast on such intuition. The aim of this paper is to bolster this intuition. It will be argued that the claim of moral asymmetry in favor of deception can be supported on a consideration of the different degrees of expectation involved in communicative ethics. Two other objections to the claim of asymmetry will also be considered.

A return-based alternative to IRR (internal rates of return) evaluations.

A dilemma often faced by healthcare financial managers is whether to describe a potential investment project to organizational decision-makers in terms of the projects' internal rates of return (IRR) or to use the net present value (NPV) method. The IRR represents an intuitively appealing method of measuring investment value, but a number of conceptual and methodological problems associated with IRR measurement would seem to argue the use of the NPV method. Unfortunately, while the NPV measure is theoretically valid, it lacks the intuitive appeal of the IRR in communicating the value of investment alternatives. This article details an alternative method of measuring return that incorporates all the intuitive appeal of the conventional IRR, but few of the shortcoming associated with that measure.

Just row.

To learn anything outside of our usual experience is to try on a new way of being. Doing something new--dealing with change--calls for a commitment to be where you are, to be present in the experiment, even while you are uncertain about the outcome. Being present and committed to the moment is as essential in management or self-management as it is in rowing a boat. How, for instance, can you tell the difference between intuition and fear? In the midst of a crisis, a change, a white water passage, a "learning opportunity," what if you get this gut feeling that something is wrong? If the feeling goes away when you drop into the present, into your body, and "just row," it's not an intuition, it's fear. The opportunity is to know the difference between opinion and intuition, between judgments and experience. Because judgments and opinions carry extraordinarily high price tags.

A new hybrid renderer for virtual bronchoscopy.

PURPOSE: To improve the diagnosis of pathologic modified airways, a new hybrid visualization system has been developed and tested based on digital image analysis and synthesis of spiral CT as well as the visual simulation of bronchoscopy. METHOD/MATERIALS: 20 patients with pathologic modifications of the airways (tumors, lung transplantation) were examined with Spiral-CT. The shape of the airways and the lung tissue is defined by an automatic volume growing method and a following geometric reconstruction by the computation of geometric primitives. This is the basis of a multidimensional display system which visualizes volumes, surfaces and computation results simultaneously. The enable the intuitive and immersive inspection of the airways a virtual reality system, consisting of two graphic engines, a head mounted display system, data gloves and specialized software was integrated. RESULTS: In 20 cases the extension of the pathologic modification of the airways could be visualized with the virtual bronchoscopy. The user interacts with and manipulates the 3D model of the airways in an intuitive and immersive way. In contrast to previously proposed virtual bronchoscopy systems the described method permits truly interactive navigation, detailed quantitation of anatomic structures and a "see through" the bronchial wall. The system enables a user oriented and fast inspection of the volumetric image data. CONCLUSIONS: To support radiological diagnosis with additional information a virtual bronchoscopy was developed. It enables the immersive and intuitive interaction with 3D Spiral CTs by truly 3D navigation in the airways. The system was tested with 20 Spiral-CTs of bronchial tumors and obstructions and is well suited for the inspection of structures beyond the bronchialtree.

[Parameters of the spatial of organization of EEG in persons with various individual characteristics].

The relationships between some characteristics of EEG topographic maps and personality traits (extraversion-introversion, sensation-intuition, thinking-feeling, judging-impulsiveness) by the Keirsey's Type Inventory were studied in 46 17-20-year-old men). The most considerable distinctions in the spatial organization of the EEG were observed between the functions sensation and intuition. The high-sensation responders were characterized by higher EEG power in the theta 1, 2 and alpha 1-bands in all derivations and higher coherence (especially in the theta 1, 2 bands most expressed in the frontoparietal areas) as compared with the high-intuition responders. The expression of extraversion was positively correlated with coherence values in the theta 1, 2 and negatively correlated with coherence in the alpha 1, 2 bands. Characteristic EEG patterns for other types of personality traits were also described. The results suggest that some characteristics of brain maps reflect the individual psychological features determined on the basis of Jung's typology.

When to trust your gut.

Many top executives say they routinely make big decisions without relying on any logical analysis. Instead, they call upon their "intuition," "gut instinct," "hunches," or "inner voice"--but they can't describe the process much more than that. What exactly is gut instinct? In this article, author Alden Hayashi interviews top executives from companies such as America Online and Johnson and Johnson to find out how they make decisions. Hayashi also presents the research of leading scientists who suggest that our emotions and feelings might not only be important in our intuitive ability to make good decisions but may actually be essential. Specifically, one theory contends that our emotions help us filter various options quickly, even if we're not consciously aware of the screening. Other research suggests that professional judgment can often be reduced to patterns and rules; indeed, truly inspired decisions seem to require an ability to see similar patterns across disparate fields. A CEO who possesses that ability can craft a perfect strategy by detecting patterns that others either overlook or mistake for random noise. But various traits of human nature can easily cloud our intuitive decision making. One potential pitfall is our tendency to see patterns where none exist. Thus, continual self-checking and feedback are crucial, and some organizations have made these processes part of their corporate culture.

"Sensing" patient needs: exploring concepts of nursing insight and receptivity used in nursing assessment.

Nursing assessment utilizes skills that enable the nurse to "sense" the patient's needs and the patient's condition, and that provide a humanistic dimension to the provision of nursing care. The explanatory concepts describing these processes include intuition, emotional empathy, inference, knowing, counter transference, compathy and embodiment. In this paper these concepts are defined, and the more commonly used concepts (i.e., intuition, empathy, and inference) are compared. The underlying assumptions and characteristics are identified and the antecedents or prerequisites, mechanisms, and outcomes of each concept are explored. While some overlap and blurring of boundaries are evident, these concepts are diverse and were developed to apply to different contexts and non-nursing situations. When used alone, none is comprehensive enough to account for nurses' ability to sense patient needs. We conclude that, given the unique aspects of nursing, we must consider using innovative methods to examine this phenomenon (e.g., the use of ethology to examine intuitively perceived changes in the patient's condition), to increase efforts to explore the newer concepts (i.e., embodiment, compathy and "knowing"), and to develop new concepts or models that better represent this complex phenomenon that better fits nursing contexts and situations.

Relationships between suicidal behavior and personality types.

This study examined the hypotheses that introversion in general and the introverted-intuitive-feeling-perceiving (INFP) type as measured by the Meyers-Briggs Type Indicator are related to suicidal ideation and behaviors. Analyses of data from 330 university students found four interactive suicidal behavior risk models: introverted-perceiving (IP) (females); introverted-sensing-feeling (ISF) (males); introverted-intuitive-perceiving (INP) (males); extraverted-intuitive-judging (ENJ) (males). Study findings were interpreted in terms of implications for risk assessment and intervention.

Understanding patients' decisions. Cognitive and emotional perspectives.

OBJECTIVE: To describe ways in which intuitive thought processes and feelings may lead patients to make suboptimal medical decisions. DESIGN: Review of past studies from the psychology literature. RESULTS: Intuitive decision making is often appropriate and results in reasonable choices; in some situations, however, intuitions lead patients to make choices that are not in their best interests. People sometimes treat safety and danger categorically, undervalue the importance of a partial risk reduction, are influenced by the way in which a problem is framed, and inappropriately evaluate an action by its subsequent outcome. These strategies help explain examples where risk perceptions conflict with standard scientific analyses. In the domain of emotions, people tend to consider losses as more significant than the corresponding gains, are imperfect at predicting future preferences, distort their memories of past personal experiences, have difficulty resolving inconsistencies between emotions and rationality, and worry with an intensity disproportionate to the actual danger. In general, such intangible aspects of clinical care have received little attention in the medical literature. CONCLUSION: We suggest that an awareness of how people reason is an important clinical skill that can be promoted by knowledge of selected past studies in psychology.

Conceptual coherence in the child's theory of mind: training children to understand belief.

Intuitive theories are defined as coherently interrelated systems of concepts that generate explanations and predictions in a particular domain of experience. 2 studies tested whether the child's theory of mind can be characterized as an intuitive theory. In Study 1, 3-year-old children who did not pass a false belief pretest were trained in 2 groups: (1) on the concept of belief, or (2) on the related concepts of desire and perception. Training took place over 2 weeks, with children given mental state tasks and receiving feedback according to their performance. Both training groups showed improved false belief performance on the posttest, compared to a control group trained on number conservation. This result is interpreted as demonstrating coherence in the child's theory of mind. In Study 2, these findings were repeated and expanded: training on belief as well as training on desire and perception resulted in improved performance on a variety of standard theory of mind posttests. Results are discussed with respect to competing theories of children's intuitive psychological knowledge.

Three dimensional image alignment, registration and fusion.

Combined assessment of three dimensional anatomical and functional images (SPECT, PET, MRI, CT) is useful to determine the nature and extent of lesions in many parts of the body. Physicians principally rely on their spatial sense to mentally re-orient and overlap images obtained with different imaging modalities. Objective methods that enable easy and intuitive image registration can help the physician arrive at more optimal diagnoses and better treatment decisions. This review describes a simple, intuitive and robust image registration approach developed in our laboratory. It differs from most other registration techniques in that it allows the user to incorporate all of the available information within the images in the registration process. This method takes full advantage of the ability of knowledgeable operators to achieve image registration and fusion using an intuitive interactive visual approach. It can register images accurately and quickly without the use of elaborate mathematical modeling or optimization techniques. The method provides the operator with tools to manipulate images in three dimensions, including visual feedback techniques to assess the accuracy of registration (grids, overlays, masks, and fusion of images in different colors). Its application is not limited to brain imaging and can be applied to images from any region in the body. The overall effect is a registration algorithm that is easy to implement and can achieve accuracy on the order of one pixel.

Responding to uncertainty in nursing practice.

Uncertainty is a fact of life for practising clinicians and cannot be avoided. This paper outlines the model of uncertainty presented by Katz (1988, Cambridge University Press, Cambridge, UK. pp. 544-565) and examines the descriptive and normative power of three broad theoretical and strategic approaches to dealing with uncertainty: rationality, bounded rationality and intuition. It concludes that nursing research and development (R&D) must acknowledge uncertainty more fully in its R&D agenda and that good-quality evaluation studies which directly compare intuitive with rational-analytical approaches for given clinical problems should be a dominant feature of future R&D.

Clinical cognition and embodiment.

I first identify two different distinctions: between Cartesian cognition and embodied cognition, and between calculative rationality and intuitive know-how. I then suggest that, in the nursing literature, these two distinctions are run together, to create an opposition between 'Cartesian rationality' and 'embodied know-how'. However, it is vital to keep the two distinctions apart, because 'embodied knowing' is very frequently rational. In separating the idea of embodied cognition from non-rational intuition, I show how 'embodiment' leads to the concepts of distributed cognition and distributed expertise. This has extensive and important implications for how we understand clinical cognition in nursing.

[Evidence-based nursing--a comprehensive term].

The connotation of Evidence Based Nursing, patient centred care, decisions in health care, intuition and evidence based on international published research is presented. A distinction between Evidence Based Medicine and Evidence Based Nursing in terms of evidence and the hierarchy of evidence is necessary. The concept of Evidence Based Nursing for the last few years has been including practical expertise and patient choice. In nursing the selection of research articles for implementation rely not solely on the evidence hierarchy but also on the model of Rycroft-Malone et al. (2002). The term Evidence Based Patient Choice was the answer to the declaration of patient rights. These rights about accurate and detailed information are essential, so that patients can actively be involved in the decision making process about the management of their disease. Nurses, therefore, must reflect and verbalize the intuition behind the decisions in a systematic and institutionalised way to include in their future decisions for similar cases the full range of evidence.

A conceptual treadmill: the need for 'middle ground' in clinical decision making theory in nursing.

This paper explores the two predominant theoretical approaches to the process of nurse decision making prevalent within the nursing research literature: systematic-positivistic approaches as exemplified by information processing theory, and the intuitive-humanistic approach of Patricia Benner. The two approaches' strengths and weaknesses are explored and as a result a third theoretical stance is proffered: the idea of a cognitive continuum. According to this approach the systematic and intuitive theoretical camps occupy polar positions at either end of a continuum as opposed to separate theoretical planes. The methodological and professional benefits of adopting such a stance are also briefly outlined.
