Do the young and the old perceive emotional intervals differently when shown on a younger or older face?
No full textMany authors have analysed the effects of emotion recognition on time perception, showing that the more arousing the stimuli are the greater is the effect on duration perception. Visual stimuli, in particular faces, are the most recurrent stimuli employed in the literature. However, pictures in which emotional faces of older individuals have rarely been used, and when used, only young participants were tested. Hence, the present study is designed not only to analyse differences as regards duration perception in younger and older participants, but also to investigate the effects of neutral, happy, and angry facial expressions on younger and older participants when younger or older faces express those emotions. Results showed overestimation when emotional stimuli were presented. Interestingly, we observed temporal underestimation when the temporal intervals were marked by the image of younger participants and this was true in particular for older adults participants. Results are discussed in accordance with the internal clock model and in accordance with an inferential/reconstructive process occurring in memory and acting on temporal judgments

Age-related changes in time production and reproduction tasks: Involvement of attention and working memory processes
No full textSeveral studies have reported age-related differences in time estimation,
which have been attributed either to a slowing of the pacemaker
rate with aging or to impaired attention and/or working resources in
older adults. Here, we compared performance of young and older
participants on time production/reproduction tasks and on working
memory, divided attention, sustained attention and executive attention
tasks. Results showed that relative to young participants, older
adults significantly under-reproduced and tended to over-produce
target durations. Neither attention nor working memory predicted
time reproduction and production performance. Conversely, when
temporal variability was considered, participants’ temporal variability
in time production tasks was exclusively accounted for by age,
whereas variability in temporal reproduction was also explained by
divided attention and working memory. Overall, our results extend
previous investigations on timing abilities in the elderly and underscore
the importance of divided attention and working memory in the
maintenance of a stable representation of durations
