Subclaims¶

q3 i? Reaction times on the concurrent auditory task were statistically indistinguishable between guided and unguided conditions, contrary to the prediction based on younger adults. → Barhorst-Cates Erica M. 2017

Barhorst-Cates Erica M., Rand Kristina M., Creem-Regehr Sarah H. (2017). Let Me be Your Guide: Physical Guidance Improves Spatial Learning for Older Adults with Simulated Low Vision. Experimental Brain Research. https://doi.org/10.1007/s00221-017-5063-8

q3 · i? · causal · r1

Same within-subjects older-adult experiment, with the auditory reaction-time task performed concurrently as a cognitive-load measure. The ANOVA on reaction time found no guidance effect; miss rates also did not differ (p = .57).

"Our results did not find support for a difference between the guided (M=.598, SE=.028) and unguided (M=.601, SE=.023) conditions for reaction time (p=.776)"
