^aData represent means and SDs for raw scores on a 7-point scale (1 = extremely pleasant and 7 = extremely unpleasant).

^bData represent the percentage of pleasant, unpleasant, and total BSIT items rated as falling in pleasant (score 1–2), neutral (score 3–5), and unpleasant (score 6–7) ranges when the valence scale was trichotimized.
