E32 Playing Tetris in Virtual Reality Environment: Spatial Perception, Perceptual Speed and Visual Working Memory Corsi Block-Tapping Task (Mueller & Piper, 2014). A computerized test of visuospatial working memory. Participants observed sequences of colored squares and reproduced them in the correct order. Sequence length ranged from three to eight squares. Reported reliability ranges from .70 to .85. Procedure The experiment was conducted across four sessions over two weeks, with one session every 3–4 days. In the first session, participants completed a short questionnaire on computer-use experience (5 minutes), followed by the pre-training phase of three cognitive tests: the card rotation test (6 minutes), the perceptual speed test (3 minutes), and the Corsi block-tapping task (5–8 minutes). Afterward, participants played Tetris for 30 minutes, aiming for the highest possible score. In the next three sessions, both groups (2D computer and VR 3D) played Tetris for 30 minutes each. In the final session, participants completed the post-training phase of the same cognitive assessments. All sessions were held at similar times of day in a quiet university room to reduce fatigue and maintain consistency. Participants were seated in both environments. Findings Preliminary analyses confirmed that the data met the assumptions for parametric testing. Accordingly, two-way mixed ANCOVAs were used to examine group differences across time points. Prior to examining the main hypotheses, one-way ANCOVAs tested baseline (T1) differences in card rotation, number comparison, Corsi block-tapping, and Tetris performance, controlling for age. No significant group differences were found (see Table 1). Table 1.
