Pan (14) extended his previous study by verifying the colours. He used visual geometrical shapes with various colours. The participants (n = 22) were asked to memorize both the colours and shape of the items. In the memory test, the participants were asked to recognize the colours and the shapes of the items that were presented earlier on. He found that participants performed better in recognizing the colour of the items than the shapes. The result supported his previous studies where colour had a stronger attention effect than the shape, F (1, 21) = 4.984, P = 0.031, η2 = 0.192. This suggests that, colours can produce a higher level of attention and is effective to increase memory performance. Therefore, it can be concluded that colours have the tendency to capture better attention level, and thus, better memory.
