Corsi block-tapping task. The Corsi block-tapping task evaluates spatial working memory. Participants were asked to repeat the pointing pattern of the examiner to a series of blocks, that were arranged in an irregular order on a board based on the original standard display developed by Corsi (1972). First participants were asked to repeat the exact same tapping pattern as the examiner (forwards). In the second part of this task participants were asked to reverse the pattern given by the examiner (backwards). Each block contained two sequences consisting of the same amount of numbers, and difficulty was increased by asking the participants to repeat increasingly longer block patterns. This process continued until the participant misses both…show more content…
The Virtual Tübingen Task (VTT) is a virtual reality environment of the town Tübingen in Germany which assesses navigation skills, designed by Van der Ham et al. (2010). The task consisted of several elements: the study phase, a scene recognition test, a route continuation test, a route ordering test and a map selection test. The participant was shown a short movie (302 seconds) of a route through the virtual environment, whereby the set speed equals walking speed. Afterwards, different aspects of knowledge about the learned route was systematically assessed by means of four tasks. The first test was the scene recognition test. This test showed 21 snapshots, of which 11 were snapshots from the movie and the other 10 were distractors which were not shown in the movie. The participant had to reply whether he/she saw the picture in the movie or not. The total score was the percentage of correctly answered responses. The second administered test was route continuation. In this test the participant was shown an image of the route, after which they were asked whether the route was continued with a left turn, straight ahead or a right turn. In total 11 images were shown. The tests until now were performed on the computer, but the following were not. The next administered test was map selection. Four closely resembling maps were shown to the participants which were supposed to represent the route that they saw in the short movie shown in the beginning. They were allowed to only chose one map. The final test was route ordering. In this task a total of 21 images were shown to the participants which were all present in the short movie. Their task was to put the images in the same order as they appeared in the short movie. Each correctly ranked image was given two points, whereas one point was given for each image put one position too early or too late in the order. A combined test score was derived of all four tests. In order to obtain one

    eCorsi Block-Tapping Task Introduction The eCorsi block-tapping task is a popular test to appraise the visuospatial working memory of individuals. The original task, developed by Michael Corsi in 1972, consists of nine identical blocks on a board. Because of technological developments, it now has various digital versions. Used by clinical neuropsychologists, and cognitive and developmental psychologists, the Corsi task is applicable with investigations of nonverbal short-term memory, gender differences
