Abstract:
Time perception is a fundamental aspect of experience and is an important element of everyday functioning. Time perception has been linked to multiple brain areas and studies have revealed time perception deficits in several neurocognitive disorders. However, the relation between time perception, mood and other elements of cognition has received little attention following acquired brain injury (ABI). Performance on measures of short and long duration time estimation were examined in relationship to performance on measures of attention, working memory, processing speed, executive functioning (i.e., inhibition, set-shifting and prospective memory) long-term memory, depression and activities of daily living (ADLs) in individuals with ABI. Due to unexpected impacts of the COVID-19 pandemic, certain domains of functioning were unable to be assessed (i.e., ADLs) and the data includes a mixed sample of individuals. The current study examined data from 9 adults who completed a variety of cognitive assessments and questionnaires to assess mentioned areas of interest. Approximately half of the participants had cognitive concerns related to ABI, and half had concerns related to learning difficulties. Significant correlations were found between the ability to estimate short intervals of time (under 50 seconds) and processing speed, prospective memory, cognitive flexibility, and visual long-term memory. The data showed an overall pattern of the short duration time estimation task correlating with more measures compared to the long duration time estimation task. Due to limited statistical power, there may have been correlations that were not detected. There do not appear to be enough consistent findings across the literature, including this study, to be able to use a single cognitive measure to predict one’s time perception abilities. Findings of the current study also support various potential neurological underpinnings of time perception suggested in previous literature, such as the dorsolateral prefrontal cortex, frontal cortex, and the hippocampus.
