Age Effects on Inattentional Blindness in Driving Study
"Explore the impact of aging on inattentional blindness and its implications for driving safety. Discover predictors and factors affecting older adults' susceptibility to inattentional blindness, including spatial proximity and attention set. Dive into research findings on the relationship between age and inattentional blindness in different studies."

Inattentional Blindness and Aging Older adults are: More susceptible to inattentional blindness. More likely to get into a traffic accident. Are these connected? Are there factors that moderate the age and inattentional blindness relationship?
Current Study Predictors of inattentional blindness: Spatial proximity Attention set match Salience Do these differentially impact older adults susceptibility?
Age and Spatial Proximity Another study found no relationship Paper Stothart, C., Boot, W. R., & Simons, D. J. (2015). Using Mechanical Turk to assess the effects of age and spatial proximity on inattentional blindness. Collabra, 1(1), 1-7. doi: 10.1525/collabra.26
Age and Attention Set No relationship found in previous study (Horwood & Beanland, 2016). Attended, ignored noticing difference: Younger adults: 25% Older adults: 63% Not significant at .05. But, relatively small sample size (n cell = 20).
Age and Salience No study has looked at this. Can increasing the salience of road hazards help prevent crashes especially among older adults?
Sample Recruited and tested online. N = 618 Age: Median = 30 Minimum = 18 Maximum = 71
Results 55% of participants noticed the unexpected object [95% confidence interval: 51%, 59%].
Results Does age moderate the impact of attention set? OR = 1.01 [0.97, 1.06] p = .650 * Shaded regions are 95% confidence bands
Results Does age moderate the impact of salience? OR = 1.01 [0.98, 1.05] p = .469 * Shaded regions are 95% confidence bands
Results Does age moderate the impact of spatial proximity? OR = 1.01 [0.98, 1.04] p = .411 * Shaded regions are 95% confidence bands
Results Extreme group analysis: Youngest 25% (n = 156; M = 22.64, SD = 2.03, Min = 18, Max = 25) Oldest 25% (n = 162; M = 49.72, SD =8.19, Min = 39, Max = 71)
Results Does age moderate the impact of attention set? OR = 1.39 [0.31, 6.79] p = .672 * Error bars represent 95% confidence intervals
Results Does age moderate the impact of salience? OR = 1.56 [0.45, 5.54] p = .484 * Error bars represent 95% confidence intervals
Results Does age moderate the impact of spatial proximity? OR = 1.31 [0.53, 3.24] p = .564 * Error bars represent 95% confidence intervals
Conclusions Replicated the age effect on inattentional blindness. However, this effect is robust to manipulations of: Attention set Spatial proximity Salience Small number of older than 65+ participants is one limitation.
