healthy subjects
First time :WISC V 40 minutes Second time :Completion of the 4 experimental tasks 105 minutes
METRIC COMPARISON Tasks : Tactile PVSE test
Tactile PVSE test The tests are presented in 6 independent booklets, each of which tests a distinct skill: comparison of lengths, comparison of sizes, comparison of obliques, perception of environments, comparison of relative positions in relation to a frame and comparison of relative positions with distractors.
The assessment sheet presented in a table with the expected answers will allow you to note whether the answers are correct (rating 1) or not (rating 0). A total of the correct answers from all the sub-tests will give a total score.
METRIC COMPARISON Tasks : Classic PVSE test
Classic PVSE test Use of the standardized PVSE test printed on thick white paper in 6 separate booklets each containing a subtest (length, size, oblique, middle, relative position and relative position with distractor)
The assessment sheet presented in a table with the expected answers will allow you to note whether the answers are correct (rating 1) or not (rating 0). A total of the correct answers from all the sub-tests will give a total score.
Mental imagery task
This involves answering questions concerning the position or identity of 2 or 3 objects on the basis of the mental representation of a grid by auditory guidance. Each grid must be constructed mentally with the verbal description of the path and the objects encountered.
Proprioceptive spatial representation tasks
16 configurations of 3 objects with direct or indirect passive exploration of their relative positions.
Each grid is presented 3 times with the following 3 questions to which the subject answers yes or no by forced choice
a single measure of the number of correct answers which will be the sum of the correct answers obtained to each of the 3 questions in the direct vs indirect condition
Tasks assessing number sense based on relative positions or lengths
Pointing exercises on a digital line of 50 cm paper tape: the participant points with his finger to a position on the tape, according to the verbal request of the experimenter
Measures the intermanual gap during requests for evaluation of 5 times the wand, subtracting the length of a wand, then dividing this length by 2.
WISC V Similarity and Span Test
The Wechsler Intelligence Scale for Children - Fifth Edition, Australian Standard (WISC-V) is an individually administered and comprehensive clinical instrument used to assess the general thinking and reasoning skills of children aged six years to 16 years. Test results include a Full-Scale Intelligence Quotient (IQ) score as well as age-equivalent rankings and scores for Verbal Comprehension, Visual Spatial, Fluid Reasoning, Working Memory and Processing Speed composites
WISC V Arithmetic subtest
The WISC-V is an individually administered, comprehensive clinical instrument for assessing the intelligence of children. The primary and secondary subtests are on a scaled score metric with a mean of 10 and a standard deviation (SD) of 3. These subtest scores range from 1 to19, with scores between 8 and 12 typically considered average.
