JLO: Judgement of Line Orientation


Test for visuospatial orientation

This test is derived from the Judgment of Line Orientation Test by Benton, Varney & Hamsher (1978), a test for visual-spatial skills, commonly associated with functioning of the parietal lobe of the right cerebral hemisphere. In contrast to test module LINO in Minds, this implementation resembles the original paper & pencil test as much as possible. Two angled line segments are always presented, that have to be matched to a set of 11 lines that are arranged in a semicircle and separated 18 degrees from each other. The set of 11 lines is always present on the screen. The researcher may choose from 2 versions which are different in difficulty: an easy version with lines of 10 different directions (including the horizontal and vertical lines), and a more difficult version where the horizontal and the vertical are missing. In principle there are 30 assignments that are preceded by 5 practice assignments.

An answer can be given by typing the 2 numbers, or by clicking on the numbers of the lines of choice, or by touching on them in case of a touch screen. The maximum score is 30, because both line segments must be correct to count in the scoring. There is a norm criterion from the literature, and normative data from a provisional norm group.
