over 18 years old (M ¼ 21.83, SD ¼ 2.26). Participants were randomly
assigned to one of four conditions created by two design factors with
two levels each: color (warm or neutral), and shape (round face-like or
neutral). All groups received the neutral external mood induction
procedure (NE) to allow for comparisons with results from Study 1. The
control group (NEND group) received in addition to the neutral mood
induction procedure (NE) the material with neutral design (ND:
neutral color and neutral shape). The NEPD group received the material
with positive emotional design (PD: warm colors and round
face-like shapes). The NERO group received the material with round
face-like shapes (RO), but neutral colors. The NECO group received the
material with warm colors (CO), but neutral shapes.
