Table 1.

Predicted performances on the different change detection tasks according to different natural attentional foci in functional tremor

	Hypothesized natural attentional focus in functional tremor				Impaired ability to attend
	Attend to motor execution	Attend to visual feedback from movement	Attend to target	Attending away from task
Target jump/Target luminance	Slightly worse than controls	Slightly worse than controls	Same as controls	Worse than controls	Worse than controls
Cursor luminance	Slightly worse than controls	Better than controls	Same as controls	Worse than controls	Worse than controls
Added cursor deviation	Better than controls	Worse than controls	Same as controls	Worse than controls	Worse than controls

Hypotheses about precisely where the attentional focus predominantly lies in functional tremor, make different predictions about their performance on the different spontaneous detection tasks. The control groups, particularly the healthy control participants, are expected to primarily focus on the target.
