question 4

Multiple Choice

In her dissertation, Dr Jones habituated babies a shade of blue near the boundary between blue and green. Following habituation, infants were shown two novel colors that differed from the habituation stimulus by identical physical amounts but one was a light green, the other a light blue (equal in luminance) . Infants showed a strong preference for the light green stimulus - suggesting infants considered this stimulus more novel than the light blue stimulus. This provides evidence for:

• A) Categorical perception of color.
• B) Rapid development of color preferences.
• C) Color perception that differs from that of adults.
• D) Quantitative differences between colors.
