Various constrained frequencies of skilled model observation, under self-controlled conditions, were examined to determine whether there was an optimal frequency of modeling for learning a dance movement. Forty-eight participants with no previous dance/gymnastics experience first did a pre-test, then learned the skill over 60 interspersed observational and physical practice trials in one of four conditions that consisted of either (1) 25%, (2) 50%, (3) 75% modeling frequencies, or (4) no constraint imposed. This 60-trials acquisition phase was followed by a 24-hour post-test. Physical performance, scored by two external evaluators, revealed a significant main effect of Time from pre- to post-test (F(1, 44) = 120.43, p < .001). Cognitive representation scores revealed a main effect of Time for an image selection test (F(1, 44) = 39.09, p < .001), and a Time by Decision interaction for a forced-choice test (F(1.53, 67.48) = 7.00, p = .004). While learning was demonstrated for all measures, evidenced by higher scores at post-test than at pre-test, no main effect of Group was obtained. Consequently, the frequencies of modeling tested here under self-controlled learning conditions were equally beneficial for the learning of the novel dance skill.

Interruption interference refers to significant decreases in performance that occur following task interruption. Evidence has suggested that practicing recovering from interruptions can reduce interruption interference as measured by the time required for resuming the interrupted task. Conflicting evidence, however, has indicated that interruption practice might only improve resumption for the practiced primary and interrupting task-pair. The studies within this dissertation utilize a transfer paradigm to resolve this conflict and determine whether or not interruption resumption practice in one task-pair context can benefit interruption resumption in a novel task-pair context. A new theory, Interruption Recovery Goal, defines the mechanisms of interruption handling skill acquisition and transfer as production consolidation that facilitates the storage and maintenance, via rehearsal, of the pre-interruption task state, as well as any planned action sequences, for retrieval after the interruption. The first two reported studies provided evidence that interruption handling skill for one task-pair context transferred to a novel task-pair when one (first study) or both (second study) tasks in the context changed. The third study supported theories that have defined the mechanism of interruption handling skill as an improvement to primary task goal state and action sequence memory, rather than reconstruction, by showing that resumption times improved even when the onscreen display of the primary task’s target state was removed at resumption. This study also supported the task-general view of interruption handling skill by providing evidence that interruption handling skill acquisition and transfer did not strongly relate to primary task skill acquisition and transfer. The fourth study tested for interruption handling skill transfer across novel interruption contexts when interruption duration, the availability of pre-interruption rehearsal, or both differed at transfer. The results showed resumption time improvements across interruption contexts, indicating that rehearsal and retrieval mechanisms vital for interruption resumption remained similar across contexts for skill transfer. Although further research is needed to understand the extent to which this transfer is fully task-general, the theory supported by these studies provides new directions for the study of interruption handling skill and has implications for the development of training methods for reducing interruption interference in high-risk workplaces.

This thesis describes the experimental work carried out as part of the Learning to be Human Project, investigating skill and learning in early flaked stone technologies. A group of 16 volunteers were studied as they learnt skills in Oldowan style flaking, Acheulean handaxe technology and Levallois preferential flake technologies. Aptitude, practice hours and hours spent in taught sessions were recorded and skill in each of these technologies was assessed at regular intervals. This information was used to answer questions concerning the acquisition of high level skill in these technologies, the role of practice, teaching and aptitude in determining skill in terms of connaissance and savoir-faire and the archaeological visibility of skill. At a more in depth level the significance of these findings for cognitive capacities of early hominins and the evolution of modern human brains and intelligence was assessed. The results of these experiments allowed the identification of the greater impact of teaching on Acheulean handaxe and Levallois technology compared to Oldowan style flaking. Technologically focussed teaching was shown to be essential for achieving high level skill in handaxe technology while all knapping contributed to the skill achieved in Oldowan style flaking and Levallois technology. In terms of aptitude, previous craft experience and contact with flaked stone assemblages most affected skill achieved in handaxe and Oldowan technologies while spatial ability best determined skill in Levallois. The findings of the connaissance and savoir-faire analysis have indicated that the differences seen between Oldowan and Acheulean technology are predominantly physical in nature, while the differences between Levallois and the earlier technologies are cognitive. This suggests a greater cognitive capacity for the Neanderthal Levallois manufacturers in contrast with the earlier hominin species. The results have, however, highlighted problems with a strict dichotomy between physical and cognitive skills. A number of material markers that could be related to skill were identified. Future work has been identified that could provide a fuller understanding of these findings.

This thesis contributes to theorising observational drawing from a cognitive perspective. Our current understanding of drawing is developing rapidly through artistic and scientific enquiry. However, it remains fragmented because the frames of reference of those modes of enquiry do not coincide. Therefore, the foundations for a truly interdisciplinary understanding of observational drawing are still inceptive. This thesis seeks to add to those foundations by bridging artistic and scientific perspectives on observational process and the cognitive aptitudes underpinning it. The project is based on four case studies of experienced artists drawing processes, with quantitative and qualitative data gathered: timing of eye and hand movements, and artists verbal reports. The data sets are analysed with a generative approach, using behavioural and protocol analysis methods to yield comparative models that describe cognitive strategies for drawing. This forms a grounded framework that elucidates the cognitive activities and competences observational process entails. Cognitive psychological theory is consulted to explain the observed behaviours, and the combined evidence is applied to understanding apparent discrepancies in existing accounts of drawing. In addition, the use of verbal reporting methods in drawing studies is evaluated. The study observes how drawing process involves a segregation of activities that enables efficient use of limited and parametrically constrained cognitive resources. Differing drawing strategies are shown to share common key characteristics; including a staged use of selective visual attention, and the capacity to temporarily postpone critical judgement in order to engage fully in periods of direct perception and action. The autonomy and regularity of those activities, demonstrated by the artists studied, indicate that drawing ability entails tacit self-knowledge concerning the cognitive and perceptual capacities described in this thesis. This thesis presents drawing as a skill that involves strategic use of visual deconstruction, comparison, analogical transfer and repetitive cycles of construction, evaluation and revision. I argue that drawing skill acquisition and transfer can be facilitated by the elucidation of these processes. As such, this framework for describing and understanding drawing is offered to those who seek to understand, learn or teach observational practice, and to those who are taking a renewed interest in drawing as a tool for thought.

The preparation of newly qualified nurses has raised many professional debates and yet the ‘end product’ of nurse education, the qualified nurse continues to demonstrate knowledge and skill deficits in areas considered essential to patient care. Technological advances in an ever-changing and complex clinical environment mean that certain acute clinical skills have become routine for the qualified nurse and yet few educational institutions and NHS Trusts in the UK have seen the need to address this within the pre-registration nursing curricula. This study, questions whether the pre-registration nursing curricula is failing newly qualified nurses by not adequately preparing them to cope with the complexities of practical skills within the clinical environment. This skill deficit is rectified on qualifying when nurses rapidly equip themselves with skills that are considered essential for practice. Using a constructivist paradigm and a mixed methods research approach, the opinion of key stakeholders in pre-registration nurse education was sought. Focus groups and surveys were conducted with skills teachers to ascertain essential skills. Constructive alignment theory (Biggs 1999) was tested with two student cohorts from a pre-registration nursing programme (n=58). Comparisons were made between an experimental group who acquired certain skills during their pre-registration programme and a control group who had not acquired those additional skills. The programme was evaluated using Stake’s (1967) countenance model of evaluation. Data were analysed using SPSS, constant comparative analysis and triangulation. The findings confirmed that nurses should acquire the skills investigated in this study, but differences of opinion were found as to when this was acceptable. Favourable results for the experimental group were demonstrated indicating the need to provide nurses with the additional skills prior to qualifying. The study also identified other like-minded UK nurse educators who had been innovative with their skills’ curricula. Nursing curricula can be successfully underpinned by an educational theory such as constructive alignment providing added value to the learner and enablingnurses to enter the profession fit for practice and purpose. To further enhance the quality and standard of provision, the following are recommended: strengthening the collaborative relationships between the key stakeholders for nurse education, as well as promoting interprofessional learning and skills development. This will help improve the international credibility for the UK skills curricula.

The aim of the present thesis was to investigate the relationship between individuals' allocation of overt visual attention during action observation and their consequent pickup of information. Four interrelated studies were conducted to achieve this. In Study 1 we examined the effects of visual guidance - colour highlighting of relevant aspects of the action - on observational learning of the golf swing. The results showed that the visual guides facilitated novices' intake of information pertaining to the model's posture, which was reflected in faster learning. In the remaining studies, transcranial magnetic stimulation and eye tracking data were acquired concurrently to measure the interaction between gaze behaviour and motor resonance - a neurophysiological index of the motor system's engagement with a viewed action, and thus a correlate of information extraction. In Study 2, we directed observers' gaze to distinct locations of the display while they viewed thumb adduction/abduction movements. The results showed that, by directing gaze to a location that maximised the amount of thumb motion across the fovea, motor resonance was maximised relative to a free viewing condition. In Study 3 we examined the link between gaze and motor resonance during the observation of transitive actions. Participants viewed reach-to-grasp actions with natural gaze, or while looking at a target- or an effector- based visual guide. The results showed that the effector-based guide disrupted natural gaze behaviour, and this was associated with a reversal of the motor resonance response. In Study 4 we showed novice and skilled golfers videos of the golf swing and of a reach-grasp-lift action. The results revealed that, for both actions, the extent of motor resonance was related to the location of participants' fixations. The present work provides the first evidence of a relationship between gaze and motor resonance and highlights the importance of appropriate gaze behaviour for observational learning.

Auditory feedback has been shown to be highly effective at teaching new skills to athletes in a variety of sports. This method consists of targeting a routine, breaking down the specific skills required to complete the routine, and training an individual on those skills using an auditory device to provide feedback on correct responses. This study evaluated the effectiveness of auditory feedback for improving a judo technique. One set of techniques taught in judo are standing throws, which require a partner to receive the technique (uke.) These throws require specific skills to successfully implement the technique. Auditory feedback was evaluated within a multiple baseline across participants design to increase skills for one specific standing throw, ippon seoi nage (one armed shoulder throw.) The skills were scored on a seven item checklist. All participants improved their performance on ippon seoi nage at a quicker pace than what was observed during baseline.

Behavioral coaching procedures have been evaluated and enhanced over the years to find the most effective interventions for athletic performance in a variety of sports settings. Different types of feedback have been evaluated for effectiveness in teaching and improving skills. The purpose of this study was to examine the effects of video modeling and video feedback to improve technique for three novice individuals in a fitness program incorporating Olympic weightlifting. Two weightlifting events, the clean and jerk and snatch, were targeted for intervention. Each lift was broken down into a task analysis, and trainers used the task analysis to score each lift. Video modeling and video feedback was effective in improving all three participant's lifts from baseline. Annie's lifts improved from 37% in baseline to 79% in intervention for the clean and jerk, and 24% to 75% for the snatch. Rich's lifts improved from 79% in baseline to 95% following intervention for clean and jerk, and 58% to 89% for the snatch. Fran improved from 60% to 87% on the clean and jerk, and from 51% to 84% on the snatch.
