Perceptions of older and younger adults who wear hearing aids

Figures & data

Table 1. Sequence of trial blocks for the YA-IAT and the OA-IAT.

		Response items
Block	No. of trials	Left hand	Right hand
1	20	No Hearing Aid	Hearing Aid
2	20	Positive	Negative
3	20	No Hearing Aid + Positive	Hearing Aid + Negative
4	40	No Hearing Aid + Positive	Hearing Aid + Negative
5	28	Hearing Aid	No Hearing Aid
6	20	Hearing Aid + Positive	No Hearing Aid + Negative
7	40	Hearing Aid + Positive	No Hearing Aid + Negative

Note. Half the participants paired No Hearing Aid and Positive stimuli in the first test blocks while the other half of participants paired Hearing Aid and Positive stimuli in the first test blocks (i.e. the position of Blocks 1, 3, and 4 were counterbalanced with the positions of Blocks 5, 6, and 7). Blocks 4 and 7 are test blocks, whereas all other blocks are practice blocks.

Note. Images of older and younger adults are from the Minear and Park (2004) Face Database.

Note. Tukey’s box plots represent the median and interquartile range (Q3-Q1). Violin plots represent the probability density of the data across the distribution. Filled circles represent the mean D score for each condition.
