This project explores the differential impact of facial cues on trust-based decision-making and adaptation to incongruent feedback among younger and older adults. It seeks to quantify the extent to which these age groups rely on visual trustworthiness cues versus outcome-based evidence in adjusting their trust assessments.
Employing the Iowa Gambling Task alongside its social variant, the study analyzes behavioral data from two age cohorts: young adults (18-30 years) and seniors (65-80 years). Through statistical analysis, it examines patterns in initial trust biases towards facial cues and subsequent adjustments in trust evaluations in response to congruent or incongruent behavioral cues.

The project leverages advanced statistical techniques to dissect the differential responses to trust cues between younger and older adults. Utilizing STATA, the study processes and analyzes behavioral data captured through the Iowa Gambling Task, emphasizing adaptability to incongruent cues. STATA and R visualization tools (e.g. ggplot2) were employed to present the findings, highlighting the age-related variances in trust adjustment mechanisms.
The findings underscore significant age-related differences in trust dynamics, particularly highlighting older adults' challenges in reconciling initial trust impressions based on facial cues with contradictory behavioral information. This research contributes to understanding vulnerability to deception with age and informs the development of targeted interventions to protect older populations from fraud and exploitation.
