![]() In the traditional version of the Corsi block-tapping test, the evaluator can inadvertently change the presentation method by using a different finger to tap the blocks, by varying the speed of tapping, especially in longer sequences, or by covering some blocks during the presentation of the sequence. It is particularly important in people with psychosis, where the context can affect their emotional state during the execution of cognitive tasks. This procedure allows information about health status to be obtained in real-time and in the real-world. Digital instruments for cognitive assessment offer several advantages, such as standardised automatic procedures and remote monitoring of health conditions in a natural, comfortable environment for the patients. In recent years, the number of neuropsychological tasks adapted to the digital context has increased significantly. It has frequently been used in individuals with various disorders: schizophrenia spectrum, first-episode psychosis, and several neurological diseases. It is a simple yet powerful instrument to measure visuospatial working memory and spatial attention. After the tapped sequence, the participant tries to mimic the tapping until he/she can no longer progress successfully. The evaluator taps the blocks in random sequences of increasing length. In the Corsi block-tapping test, which consists of nine identical blocks on a board, participants are asked to repeat the sequence given by the evaluator in the same or reverse order. Despite the extensive literature related to WM dysfunction in this population, there remains considerable debate regarding how best to measure this cognitive domain. WM has also been noted as a predictor of occupational functioning and has been related to improvements in psychological functioning following cognitive remediation in individuals with psychotic disorders. However, the latter deficits were more consistent and robust than those observed in verbal WM across studies. For example, a meta-analysis by Lee and Park reported WM deficits in both verbal and visuospatial tasks in individuals with schizophrenia. Although WM deficits are well documented in psychosis, their magnitude and consistency vary depending on the tasks used. Working memory (WM) deficit is a core cognitive dysfunction among people with Schizophrenia Spectrum Disorders. Further, it is easy to administer while ensuring a standard procedure. The digital Corsi might be used to enhance clinical practice diagnosis and treatment.The digital version can be administered in a natural environment in real-time. The traditional Corsi test was positively related to intelligence and verbal working memory, probably due to a more significant effort to execute the test. Overall, patients performed worse with respect to the healthy comparison group. The digital version, as well as the traditional version, can discriminate between patients with psychosis and healthy controls. Results were consistent between the traditional and digital versions of the Corsi test. Both groups completed a neuropsychological assessment involving attention and working memory divided into the two conditions. This study aimed to compare the digital and traditional versions of the Corsi test in 45 patients with psychotic disorders and 45 healthy controls. In recent years, the number of digital instruments has increased significantly several advantages might derive from the use of a digital version of the Corsi test. The traditional version is composed of 9 square blocks positioned on a physical board. The Corsi block-tapping test is a widely-used instrument to assess visuospatial working memory. Impairment in working memory is a core cognitive deficit among individuals with psychotic disorders. Working memory (WM) refers to the capacity system for temporary storage and processing of information, which is known to depend on the integrity of the prefrontal cortex. ![]()
