One important feature of a neuropsychological test is its ecological validity, which defines how much patients’ test scores are linked to real-life functioning. However, many of the currently available neuropsychological tools show low to moderate levels of ecological validity. Virtual reality (VR) emerged as a possible solution that might enhance the ecological value of standard paper-and-pencil tests, thanks to the possibility of simulating realistic environments and situations where patients can behave as they do in real life. Moreover, a recent kind of virtual environments, the 360° spherical photos and videos, seems to guarantee high levels of graphical realism and lower technical complexity than standard VR, despite their limitations concerning interactive design. In this pilot study, we tested the possible application of 360° technology for the assessment of memory, developing an adaptation of a standardized test. We focused on Free Recall and Recognition accuracies as indexes of memory function, confronting and correlating the performances obtained by the participants in the standard and in the 360° test. The results, even if preliminary, support the use of 360° technology for enhancing the ecological value of standard memory assessment tests.

Abstract
One important feature of a neuropsychological test is its ecological validity, which defines how much patients’ test scores are linked to real-life functioning. However, many of the currently available neuropsychological tools show low to moderate levels of ecological validity. Virtual reality (VR) emerged as a possible solution that might enhance the ecological value of standard paper-and-pencil tests, thanks to the possibility of simulating realistic environments and situations where patients can behave as they do in real life. Moreover, a recent kind of virtual environments, the 360° spherical photos and videos, seems to guarantee high levels of graphical realism and lower technical complexity than standard VR, despite their limitations concerning interactive design. In this pilot study, we tested the possible application of 360° technology for the assessment of memory, developing an adaptation of a standardized test. We focused on Free Recall and Recognition accuracies as indexes of memory function, confronting and correlating the performances obtained by the participants in the standard and in the 360° test. The results, even if preliminary, support the use of 360° technology for enhancing the ecological value of standard memory assessment tests.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
