The present study aims to investigate the aspects of time perception related to the processes of aging, conceptualized as change throughout the life span. The high complexity of the factors involved in time perception processes means that, despite various classical and recent interpretations, we still do not know exactly which mechanisms underlie them. Each research in this field can only address a small aspect of psychological time at once. In our study, which involved 28 young and 26 elderly participants, we focus on explicit timing, comparing the data from the young group with that of the elderly group. The investigation is based on the Bisection task carried out concurrently with EEG measurement. Both behavioural outcomes and beta frequency bands of the EEG trace are considered, along with the possible correlation with the values obtained in the Stress subscale of the DASS-21 questionnaire.
Il presente studio si propone di indagare gli aspetti della percezione del tempo legati ai processi dell’invecchiamento, inteso come il cambiamento lungo l’arco della vita. L’alta complessità dei fattori che vengono coinvolti nei processi della percezione del tempo fa sì che, nonostante diverse interpretazioni sia classiche che recenti, non sappiamo ancora quali meccanismi ne siano alla base. Ogni ricerca in questo campo può affrontare di volta in volta solo un piccolo aspetto del tempo psicologico. Nel nostro studio, a cui hanno preso parte 28 partecipanti giovani e 26 anziani, focalizziamo l’attenzione sul tempo esplicito, mettendo a confronto i dati del gruppo giovani con i dati del gruppo anziani. L’indagine poggia sul compito Bisezione eseguito in concomitanza con la misurazione EEG. Si considerano sia gli outcame comportamentali che le bande di frequenza beta del tracciato EEG e la possibile correlazione con i valori ottenuti nella sottoscala Stress del questionario DASS_21.

Abstract
The present study aims to investigate the aspects of time perception related to the processes of aging, conceptualized as change throughout the life span. The high complexity of the factors involved in time perception processes means that, despite various classical and recent interpretations, we still do not know exactly which mechanisms underlie them. Each research in this field can only address a small aspect of psychological time at once. In our study, which involved 28 young and 26 elderly participants, we focus on explicit timing, comparing the data from the young group with that of the elderly group. The investigation is based on the Bisection task carried out concurrently with EEG measurement. Both behavioural outcomes and beta frequency bands of the EEG trace are considered, along with the possible correlation with the values obtained in the Stress subscale of the DASS-21 questionnaire.| File | Dimensione | Formato | |
