In studies of human eye-head coordinated saccadic gaze shifts, different laboratories have found greatly different magnitudes of head movements for a given amplitude of gaze shift (head movement gain). The present study was conducted to examine why, and to quantify volitional head movements.

Human Factors: The Journal of the Human Factors and Ergonomics Society, 2017
Objective: The aim of this study was to measure head rotation movement times in a Fitts’ paradigm and to investigate the transition region from ballistic movements to visually controlled movements as the task index of difficulty (ID) increases. Background: For head rotation, there are gaps in the knowledge of the effects of movement amplitude and task ...

The Magnitude of Translational Head Movements
Optica Acta: International Journal of Optics, 1969Results are presented from an experiment to measure the magnitude of translational head movements during steady fixation when the head was supported in various ways. The significance of the results for eye movement recording is discussed.

This paper will focus on the treatment of so-called verb movement phenomena within non-transformational approaches to grammar, namely Categorial Grammar (CG) and Head Driven Phrase Structure Grammar (HPSG). We will discuss a number of recent proposals put forward by categorial grammarians, including one of the approaches taken within the LILOG project,

Head Movement and Morphological Strength
2020In the Principles and Parameters framework of Generative Grammar, the various positions occupied by the verb have been identified as functional heads hosting inflectional material (affixes or features), which may or may not attract the verb. This gave rise to a hypothesis, the Rich Agreement Hypothesis (RAH), according to which the verb has to move to ...

Head Movement in Linguistic Theory
Linguistic Inquiry, 2006In this article, I address the issue of head movement in current linguistic theory. I propose a new view of the nature of heads and head movement that reveals that head movement is totally compliant with the standardly suggested properties of grammar. To do so, I suggest that head movement is not a single syntactic operation, but a combination of two ...

Head Movement and Complex Heads
2002Abstract The topic of this chapter is head movement and the formation of complex heads. Of the syntactic processes and configurations claimed in section 1.4.3 to give rise to complex words, head movement is far more widely recognized than the others.

Comparison of kinematics of imposed head movements and head movements in free space
2021Main research question: The correct positioning of the head and neck is essential during electrical wheelchair use. Therefore, proper head support is important for persons with impaired head stabilization and/or positioning. Existing systems often provide only static, fixed head support, while during daily life support of different head support ...

Natural Language & Linguistic Theory, 1998
Considerable importance has been attributed to the problem of restricting the theory, but nevertheless certain options that generative transformational grammar provides have remained largely untouched. In the present article, one such issue is broached, viz., that of the choice between substitution and adjunction.
