Joint attention has been extensively studied in the developmental literature because of overwhelming evidence that the ability to socially coordinate visual attention to an object is essential to healthy developmental outcomes, including language learning. The goal of this study was to understand the complex system of sensory-motor behaviors that…

Observing actions and understanding sentences about actions activates corresponding motor processes in the observer-comprehender. In 5 experiments, the authors addressed 2 novel questions regarding language-based motor resonance. The 1st question asks whether visual motion that is associated with an action produces motor resonance in sentence…

Literature is reviewed which discusses the role of proprioceptors in basic perceptual and motoric functions. The author cites research on the functions of the muscle spindles in controlling muscles which in turn provide energy, stimulation, and activation of the central nervous system. Research on the relation of motor functions to language…

Investigates developmental changes in the accuracy of aimed movements made to an illuminated target lamp by children between the ages of 1.5 and 8 years. Shows accuracy decreased with decreasing availability of visual information and improved with age under all conditions. (HOD)
