Justin Christensen deals with the bond between improvisation and imagination in artistic experience. Starting with a reassessment in continental philosophy both of how imagination is conceived and can be demonstrated, Christensen observes that the connection between improvisation and imagination has previously had little value in classic aesthetic theories. He then goes on to argue for the value of improvisation as a reflection of perception–action coupling that is central to newer theories that favor embodied approaches to music cognition. In the light of such theories, where perception, action, and imagination are seen as interdependent properties, Christensen proposes a greater recognition of the processes of musicking—including improvisation—to better understand meaning-making and the role of imagination in musical experience.

Abstract Interlimb coordination is critical to the successful performance of simple activities in everyday life and it depends on precisely timed perception-action coupling. This is particularly true in music-making, where performers often use body-movements to keep the beat while playing more complex rhythmic patterns. In the current study, we used a musical rhythmic paradigm of simultaneous rhythm/beat performance to examine how interlimb coordination between voice, hands and feet is influenced by the inherent hierarchical relationship between rhythm and beat. Sixty right-handed participants—musicians, amateur-musicians and non-musicians—performed three short rhythmic patterns while keeping the underlying beat, using 12 different combinations of voice, hands and feet. Results revealed a bodily hierarchy with five levels 1) left foot, 2) right foot, 3) left hand, 4) right hand, 5) voice, implying a more precise task execution when the rhythm was performed with a limb occupying a higher level in the hierarchy than the limb keeping the beat. The notion of a bodily hierarchy implies that the role assigned to the different limbs is key to successful interlimb coordination: the performance level of a specific limb combination differs considerably, depending on which limb holds the supporting role of the beat and which limb holds the conducting role of the rhythm. Although performance generally increased with expertise, the evidence of the hierarchy was consistent in all three expertise groups. The effects of expertise further highlight how perception influences action: Embracing a predictive coding view, we discuss the possibility that musicians’ more robust metrical prediction models make it easier for musicians to attenuate prediction errors than non-musicians. Overall, the study suggests a comprehensive bodily hierarchy, showing how interlimb coordination is influenced by hierarchical principles in both perception and action.

Abstract Event

Abstract Event-related desynchronization/synchronization (ERD/ERS) at alpha (10Hz), beta (20Hz), and gamma (40Hz) bands and movement-related potentials (MRPs) were investigated in right-handed subjects who were “free” to decide the side of unilateral finger movements (“fixed” side as a control). As a novelty, this “multi-modal” EEG analysis was combined with the evaluation of involuntary mirror movements, taken as an index of “bimanual competition.” A main issue was whether the decision regarding the hand to be moved (“free” movements) could modulate ERD/ERS or MRPs overlying sensorimotor cortical areas typically involved in bimanual tasks. Compared to “fixed” movements, “free” movements induced the following effects: (1) more involuntary mirror movements discarded from EEG analysis; (2) stronger vertex MRPs (right motor acts); (3) a positive correlation between these potentials and the number of involuntary mirror movements; (4) gamma ERS over central areas; and (5) preponderance of postmovement beta ERS over left central area (dominant hemisphere). These results suggest that ERD/ERS and MRPs provide complementary information on the cortical processes belonging to a lateralized motor act. In this context, the results on vertex MRPs would indicate a key role of supplementary/cingulate motor areas not only for bimanual coordination but also for the control of “bimanual competition” and involuntary mirror movements.

AbstractAgility is an important skill for both attackers and defenders in invasion sports such as codes of football. On the sporting field, agility requires reacting to a stimulus, often presented by an opponent’s movement, before a change of direction or speed. There is a plethora of research that examines the movement component of agility in isolation, which is described as change-of-direction (COD) ability, and this is thought to underpin agility performance. This opinion article proposes that COD ability should not be researched as the only or primary outcome measure when the objective is to inform agility performance in invasion sports. It is argued that pre-planned COD movements and tests lack ecological validity because they lack perception-action coupling and involve movement out of context from the game. The movement techniques and strength qualities required for the performance of COD tests can be quite different to those required for agility. It is suggested that COD tests can be applied to sports that involve pre-planned COD movements, but researchers should endeavour to use agility tests when studying invasion sports. Some new methods for assessing one-on-one agility contests are reported as potentially valuable for future research, and examples of research questions are provided.

The Relationship

The role of visual problems in learning disability has been a source of considerable controversy for many years. One major issue in the continuing argument is the frequent confusion of labels and concepts in the visual field. It is important to view vision as a psychophysiologic mechanism and to differentiate it from a mechanistic orientation emphasizing the eyes. Most visual problems related to learning disability represent a breakdown in the ability of the eyes to function in an harmonious fashion, that is, some interference in binocular function. While visual defects should not be confused with defects in visual perception, the identification and treatment of visual problems is an important element in the diagnosis and remediation of learning disabilities.

Twenty-one children with Down syndrome (DS) and 20 without disability, ages 3 to 11 years, completed the experiment in which they were asked to grasp and lift cardboard cubes of different sizes (2.2 to 16.2 cm in width). Three conditions were used: (a) increasing the size from the smallest to the largest cube, (b) decreasing the size from the largest to the smallest, and (c) a random order of sizes. Children with DS were found to have smaller hand sizes in comparison to age-matched children without DS. In addition, the shift from one-handed to two-handed grasping appeared at a smaller cube size for children with DS than for children without DS. However, when the dimensionless ratio between object size and hand size was considered, the differences between groups disappeared, indicating that the differences in grasping patterns between children with and without DS can be attributed to differences in body size.

Abstract Researching the role of media within young people’s socialization requires an integrative approach that understands socialization as a contextual, interlinked process in which children construct their approach to life against the background of ‘developmental tasks’ and of the relevant social contexts. This article presents a praxeological approach that combines subjective and structural components of practice and that has been put into practice by means of a qualitative longitudinal-panel study on children’s socialization. The approach is based on three analytical concepts, options for action, outlines for action, and competences for action, and advances an interlinkage of subjective perception, action-driving orientations, and everyday-life practices against the backdrop of (changing) socio-structural conditions.
