Dualistic approaches to the mind-body relationship are commonplace; however, the adoption of dualistic thinking can often obscure aspects of the way the organism functions as a whole biological entity. Future versions of the emulation theory will, it is hoped, address some of these issues, including the nature of process noise, how distinct iterations can occur, and how to deal with non-emulated aspects of motor control.

The way in which we move influences our ability to perceive, interpret and predict the actions of others. Thus movements play an important role in social cognition. This review article will appraise the literature concerning movement kinematics and motor control in individuals with autism, and will argue that movement differences between typical and autistic individuals may contribute to bilateral difficulties in reciprocal social cognition.

This paper illustrates lessons we learned from user trials. Our brief was to design product graphics to encourage fast and accurate use of a new point-of-sale laser scanner. Our early intuitions were proved wrong. We had thought that the most effective design would explain how the scanner works. But our tests showed that this confused users. So instead we concentrated on guiding people to successful behaviour, without concern for the way the scanner works. Tests with typical users indicated the best graphic - simple, familiar, conspicuous, and easy to name. It significantly increased the acceptability of the product and improved the speed and accuracy with which people used it, even though it encouraged an incorrect model of the way the scanner works. This finding has implications for the design of graphics and metaphors for all kinds of user interfaces. Additionally, user trials proved invaluable in challenging our mistaken assumptions and in guiding us to an effective solution.

The Motor Theory of Speech Perception is a proposed explanation of the fundamental relationship between the way speech is produced and the way it is perceived. Associated primarily with the work of Liberman and colleagues, it posited the active participation of the motor system in the perception of speech. Early versions of the theory contained elements that later proved untenable, such as the expectation that the neural commands to the muscles (as seen in electromyography) would be more invariant than the acoustics. Support drawn from categorical perception (in which discrimination is quite poor within linguistic categories but excellent across boundaries) was called into question by studies showing means of improving within-category discrimination and finding similar results for nonspeech sounds and for animals perceiving speech. Evidence for motor involvement in perceptual processes nonetheless continued to accrue, and related motor theories have been proposed. Neurological and neuroimaging results have yielded a great deal of evidence consistent with variants of the theory, but they highlight the issue that there is no single “motor system,” and so different components appear in different contexts. Assigning the appropriate amount of effort to the various systems that interact to result in the perception of speech is an ongoing process, but it is clear that some of the systems will reflect the motor control of speech.

AbstractI identify and characterize the kind of personal-level control-structure that is most relevant for skilled action control, namely, what I call, “practical intention”. I differentiate between practical intentions and general intentions not in terms of their function or timing but in terms of their content. I also highlight a distinction between practical intentions and other control mechanisms that are required to explain skilled action. I’ll maintain that all intentions, general and practical, have the function specifying (and thus guiding according to those specifications), sustaining, and structuring action but that several functions that have been attributed to proximal intentions are actually implemented by other control mechanisms that are not themselves best identified as intentions. Specifically, I will claim that practical intentions do not initiate, monitor, specify or guide the fine-grained, online, kinematic aspects of action. Finally, I suggest that the way in which practical and general intentions should be differentiated is in terms of their content, where general intentions specify the overall goal, outcome, or end of an action as it is conceived of by the agent at a time, and practical intentions determine the means to that end. I conclude by providing empirical evidence to support this way of characterizing the intentions that “interface” with the mechanisms of motor control. Though this discussion has repercussions for action in general, I will limit my discussion to cases of skill.

We describe the anatomy of all the primary motor neurons in the fly proboscis and characterize their contributions to its diverse reaching movements. Pairing this behavior with the wealth of Drosophila’s genetic tools offers the possibility to study motor control at single-neuron resolution, and soon throughout entire circuits. As an entry to these circuits, we provide detailed anatomy of proboscis motor neurons, muscles, and joints. We create a collection of fly strains to individually manipulate every proboscis muscle through control of its motor neurons, the first such collection for an appendage. We generate a model of the action of each proboscis joint, and find that only a small number of motor neurons are needed to produce proboscis reaching. Comprehensive control of each motor element in this numerically simple system paves the way for future study of both reflexive and flexible movements of this appendage.

AbstractObjectives Growing evidence demonstrates that (a) executive functioning (EF) becomes deleteriously affected by engagement in the emotion regulation strategy known as expressive suppression and (b) EF shows considerable functional and neuroanatomical overlap with motor output. The current study aimed to bridge these two literatures by examining the relationships between naturally occurring expressive suppression and several different aspects of motor output, including action planning, action learning, and motor-control speed and accuracy. In addition, we investigated whether any identified relationships could be explained by EF. Methods Fifty-one healthy young adults completed selected subtests from the Delis-Kaplan Executive Function System as indices of EF, a self-report measure of expressive suppression, and a computerized motor sequencing task (Push Turn Taptap task; PTT) designed to assess action planning, action learning, and motor control speed and accuracy. Results Hierarchical regressions using each aspect of PTT performance as the dependent variable revealed that higher than usual self-reported expressive suppression on the day of testing (relative to the 2 weeks preceding testing) was associated with longer action-planning latencies. This relationship was fully explained by EF. No other PTT variables related to expressive suppression on the day of testing. Conclusions These results suggest that increased expressive suppression in daily life is associated with slower action planning, an aspect of motor output that is reliant on EF, highlighting the importance of factors that lead to intra-individual fluctuations in EF and motor performance.
