Evidence for implicit sequence learning in dyslexia

DYSLEXIA, Issue 1 2002
Steve W. Kelly
Abstract Nicolson and Fawcett (Cognition 1990; 35: 159,182) have suggested that a deficit in the automatization of skill learning could account for the general impairments found in dyslexia. Much of the evidence for their claims has been collected via a dual task paradigm, which might allow for alternative explanations of the data. The present study examines automatic skill learning in a single task paradigm and extends previous studies by independently examining the contribution of stimulus-based and response-based learning. The task replicates Mayr's (J. Exp. Psychol.: Learning Memory Cognition 1996; 22: 350,364) methodology in the Serial Reaction Time task by exposing participants to two structured displays, simultaneously. Learning is measured by comparing RT to the learned sequence against RT to a random display. This study demonstrates learning for both dyslexic and control groups for a spatial sequence which was observed and a concurrent non-spatial sequence which was responded to via a keypress. Learning of the sequence did not seem to depend on awareness of the sequence structure. These results suggest that automatic skill learning is intact in dyslexic individuals.

Assembly, tuning, and transfer of action systems in infants and robots

INFANT AND CHILD DEVELOPMENT, Issue 1 2008
Luc Berthouze
Abstract This paper seeks to foster a discussion on whether experiments with robots can inform theory in infant motor development and specifically (1) how the interactions among the parts of a system, including the nervous and musculoskeletal systems and the forces acting on the body, induce organizational changes in the whole, and (2) how exploratory behaviour and selective informational signals at the timescale of skill learning may allow behaviour to become stabilized at the longer timescale of development. The paper describes how three generative principles, inspired from developmental biology and shown to underlie the dynamics of infants learning to bounce in a Jolly Jumper, were broken into a set of mechanisms suitable for controlling a robotic system and resulted in a similar developmental profile. A comparison of infant and robot data leads to a set of criteria for improving the usefulness of robotic studies. Copyright © 2008 John Wiley & Sons, Ltd. [source]

Task-specific training: evidence for and translation to clinical practice

OCCUPATIONAL THERAPY INTERNATIONAL, Issue 3-4 2009
Isobel J. Hubbard
Abstract There is mounting evidence of the value of task-specific training as a neuromotor intervention in neurological rehabilitation. The evidence is founded in the psychology of motor skill learning and in the neuroscience of experience-dependent and learning-dependent neural plastic changes in the brain in animals and humans. Further, there is growing empirical evidence for the effectiveness of task-specific training in rehabilitation and for neural plastic changes following task-oriented training. In this paper, we position the evidence for task-specific training in the context of rehabilitation; review its relevance for occupation-based neurological rehabilitation, particularly in relation to upper limb function and everyday activities; and recommend evidence-driven strategies for its application. We recommend that task-specific training be routinely applied by occupational therapists as a component of their neuromotor interventions, particularly in management related to post-stroke upper limb recovery. Specifically, we propose five implementation strategies based on review of the evidence. These are: task-specific training should be relevant to the patient/client and to the context; be randomly assigned; be repetitive and involve massed practice; aim towards reconstruction of the whole task; and be reinforced with positive and timely feedback.

The effects of ageing and cognitive impairment on on-line and off-line motor learning

APPLIED COGNITIVE PSYCHOLOGY, Issue 2 2010
Jin H. Yan
Skilled performance is a collective function of practice-related experiences (online learning) and post-practice memory consolidation during sleep (offline learning). This study examines the effects of ageing and cognitive impairment on the on- and offline learning of a point-to-point arm movement. In a 3-day experiment, older adults (cognitively normal or impaired) and young adults (YAs) were randomly assigned to practice or no-practice conditions. Changes in the dependent measures of movement time and timing error were analysed within and between conditions across days. The findings suggest that both age and cognitive function affect skill learning. YAs improved performance via both on- and offline learning whereas older adults with normal cognitive capacities appeared to learn the movement skill primarily in an online mode. Cognitive impairments were found to hinder both types of skill learning. Implications for motor skill acquisition and rehabilitation are briefly discussed. Copyright © 2009 John Wiley & Sons, Ltd.

The evolution of learning

BIOLOGICAL REVIEWS, Issue 2 2004
Bruce R. Moore
ABSTRACT Most processes or forms of learning have been treated almost as special creations, each as an independent process unrelated to others. This review offers an evolutionary cladogram linking nearly one hundred forms of learning and showing the paths through which they evolved. Many processes have multiple forms. There are at least five imprinting processes, eleven varieties of Pavlovian conditioning, ten of instrumental conditioning, and eight forms of mimicry and imitation. Song learning evolved independently in at least six groups of animals, and movement imitation in three (great apes, cetaceans and psittacine birds). The cladogram also involves at least eight new processes: abstract concept formation, percussive mimicry, cross-modal imitation, apo-conditioning, hybrid conditioning, proto-pantomime, prosodic mimicry, and image-mediated learning. At least eight of the processes evolved from more than one source. Multiple sources are of course consistent with modern evolutionary theory, as seen in some obligate symbionts, and gene-swapping organisms. Song learning is believed to have evolved from two processes: auditory imprinting and skill learning. Many single words evolved from three sources: vocal mimicry, discrimination learning, and abstract concept formation. [source]
