Aging and perceived event structure as a function of modality.

Area of Science:

• Cognitive Psychology
• Developmental Psychology
• Neuroscience

Background:

• Research on situation model processing in older adults primarily uses text-based narratives.
• Existing studies indicate that situation model construction is largely preserved and may improve with age.
• The generalizability of these findings to visually-based narratives is largely unknown.

Purpose of the Study:

• To investigate the impact of story modality (text vs. visual) on event segmentation in older and younger adults.
• To determine if age-related differences exist in event segmentation across different narrative formats.
• To assess the role of situation models in event comprehension across modalities for different age groups.

Main Methods:

• Participants (older and younger adults) read text versions or viewed picture versions of stories.
• Participants segmented the narratives into distinct events.
• Segmentation judgments were compared against a theoretical analysis of situational feature shifts.

Main Results:

• Both older and younger adults demonstrated comparable alignment between their event segmentation and the theoretical analysis.
• This alignment was consistent across both text and picture modalities.
• No significant differences were found in the ability to segment events based on modality or age group.

Conclusions:

• Situation models provide a stable foundation for event comprehension in older adults, irrespective of narrative modality.
• Age does not significantly impair the ability to construct situation models for event comprehension across visual and textual formats.
• Findings suggest cognitive processes underlying situation model construction are robust and adaptable to different sensory inputs in aging.
