Preference of C-tactile optimal (3 cm/s) compared to C-tactile suboptimal stroking across age groups (affective touch index). Data from the present paper are aggregated with data from (Sehlstedt et al., 2016) for visualization purpose. The proportion of individuals in the respective age group that preferred stroking with 3 cm/s over stroking with 30 cm/s is indicated in black. There were no significant differences between the age groups in velocity preference.
