TEMPORAL INTEGRATION

&

HEALTHY AGEING

Jefta Daniël Saija

1. Merging temporal integration appears to be a high-level, modality-independent process, in which temporal coordinates of different stimuli in a temporal integration window are not retained, as is in line with the concept of a functional moment. (Chapter 2)

2. Aging leads to longer temporal integration windows, but this effect is more pronounced in vision than in audition. (Chapter 3)

3. When controlled for hearing loss, older individuals also benefit from phonemic restoration, and sometimes even more than young adults. (Chapter 4)

4. Older individuals analyze speech information over longer intervals, which seems to enable them to more effectively use their language skills and vocabulary to enhance understanding speech that is partially inaudible. (Chapter 4)

5. Speech that is interrupted with silent gaps at the syllabic rate is least intelligible, but the addition of noise bursts in these gaps allows for the largest phonemic restoration benefit. (Chapter 4)

6. Speech comprehension seems facilitated by a less merging form of temporal integration that extracts and analyzes fast auditory information, and which connects functional moments of shorter speech segments into longer experienced moments of slow information.
