An experience of supervision with nurses

Abstract

Clinical supervision is a concept that the nursing profession in the last two years has had to embrace. Clinical supervision, as denned by the Chief Nurse, is ‘a formal arrangement that enables nurses, midwives and health visitors to discuss their work regularly with another experienced professional, and involves reflecting on practice in order to learn from experience and improve competence’ (Moores 1996).     

Measuring Television Message Complexity as Available Processing Resources: Dimensions of Information and Cognitive Load

This article further tests the theoretical hypotheses supporting the use of number of camera changes (cc) and information introduced (ii) as indicators of resources allocated and resources required to process television messages. These two measures, combined, yield an indicator of available resources and can, therefore, be used as an indicator of television message complexity. Previous research has validated their use, averaged over time, as a global measure of message complexity. The two studies reported here test the underlying local complexity predictions and present support from two studies for the ii, cc combination as a valid indicator of local message complexity. Study 1 demonstrates that when a camera change has an increasing number of ii dimensions available resources become scarcer, eventually reaching cognitive overload. Study 2 examines the relative level of resources required for each of the seven dimensions, and demonstrates that specific theoretical groupings of dimensions (novelty, motivational, and cognitive) show differential impact on available resources. Results show that the individual dimensions increase required resources as predicted and that emotion change is the most cognitively taxing dimension. Together, the two studies increase our understanding of how the number of dimensions each individual dimension of ii increases cognitive load and provide strong support for the measure as an indicator of local message complexity.     

The development of numerical estimation: evidence against a representational shift

How do our mental representations of number change over development? The dominant view holds that children (and adults) possess multiple representations of number, and that age and experience lead to a shift from greater reliance upon logarithmically organized number representations to greater reliance upon more accurate, linear representations. Here we present a new theoretically motivated and empirically supported account of the development of numerical estimation, based on the idea that number‐line estimation tasks entail judgments of proportion. We extend existing models of perceptual proportion judgment to the case of abstract numerical magnitude. Two experiments provide support for these models; three likely sources of developmental change in children’s estimation performance are identified and discussed. This work demonstrates that proportion‐judgment models provide a unified account of estimation patterns that have previously been explained in terms of a developmental shift from logarithmic to linear representations of number.     

A simple method to record arm positioning movements in man with an Apple computer

This paper describes a simple method to record arm positioning movements in humans, via the game paddle entry of an Apple computer. A machine language subroutine reads the successive positions of a rotating potentiometer, with an angular accuracy of .5 deg and a time interval between two measures of 2.5 msec, and stores them sequentially in RAM memory. These measures can be retrieved for further computations of movement parameters.     

Isolating Unconscious Influences: The Neutral Parameter Procedure

Earlier demonstrations of unconscious learning have been regularly challenged. In this paper, we suggest that earlier demonstrations were not compelling due to certain properties of the experimental situations, and notably that conscious exploitation of explicit knowledge, if present, would coincide or conflict with the results of unconscious processing. We designed a method consisting of inducing a neutral behavioural change in the way subjects drew geometric figures. Two experiments showed that important and long-lasting modifications of drawing behaviour were obtained following specially devised practice, although these modifications could not be expected from deliberate adaptive strategies. In addition, we showed that subjects were unaware of the manipulation to which they had been exposed. The study provides striking evidence for unconscious learning and offers insights for the design of suitable new tools to investigate unconscious cognition.     

Expressing Coreference in French: Cognitive Constraints and Development of Narrative Skills

This study looks at how coreference is expressed under various oral production conditions and at various stages of development. Seven- to 11-year-old children and adults told silent comic strip stories involving two characters to a same-age peer. The stories varied as to: (1) the frame presentation mode, (2) the links between events across frames, and (3) thematic continuity. The results showed that, (1) in general, all speakers marked increasing referent givenness (the 7-year-olds and adults less so than the 11-year-olds), (2) arbitrarily placed picture sequences led to a greater number of markers of increasing referent givenness than ordered sequences (which made it easier to put the information into story format), and (3) speakers were more inclined to tell the story when the frames were shown all at once (on the same page) than when they were presented in booklet format (one frame per page). The manipulation of the production conditions turned out to be an effective way of revealing speaker competence. In step-by-step encoding where the pictures were discovered one at a time, 7-year-old children exhibited a greater tendency to describe each frame as an independent entity, 11-year-old children always marked increasing referent givenness, and adults maintained coreference in a more flexible manner by varying the markers used to express referent givenness. The viewing of all frames at once before encoding provided support for the expression of emerging narrative skills. This condition enabled the 7-year-olds to no longer describe the pictures independently, promoted the marking of increasing referent givenness between the ages of 7 and 9, and pointed out the age (9 years) when the speakers began to mark coreference as a function of how the story ended.     

Cognitive effort during note taking

Note taking is a complex activity that requires comprehension and selection of information and written production processes. Here we review the functions, abbreviation procedures, strategies, and working memory constraints of note taking with the aim of improving theoretical and practical understanding of the activity. The time urgency of selecting key points and recording them while comprehending new information at the same time places significant demands on the central executive and other components of working memory. Dual‐ and triple‐task procedures allow the measurement of the momentary cognitive effort or executive attention allocated to note taking. Comparative data show that note taking demands more effort than reading or learning. However, it requires less effort than the creative written composition of an original text.
