  2. Cue indicate attention deployment “ • No difference of with and without attention in sensitivity for luminance increment and unique feature. Bonnel, A. M., Stein, J. F., & Bertucci, P. (1992). Does attention modulate the perception of luminance changes?. The Quarterly Journal of Experimental Psychology, 44(4), 601-626.

  3. “ • No difference of with and without attention in sensitivity for luminance increment and unique feature. Nakayama, K., & Mackeben, M. (1989). Sustained and transient components of focal visual attention. Vision research, 29(11), 1631-1647.

  4. Unique feature popping out:Lateral inhibitionpre-attentively, parallel

  5. Attention effect of early visual processing 1. Contrast threshold 2. Orientation threshold 3. Unidirectional offset threshold 4. bidirectional offset threshold

  6. Manipulating attention effect:Dual task

  7. Manipulating attention effect:Dual task Secondary task Primary task

  8. Attention demanding task • Form identification • 5 T/L: same • 1T/L and 4 L/T: diff. response Braun, J. (1994). Visual search among items of different salience: Removal of visual attention mimics a lesion in extrastriatearea V4. The Journal of Neuroscience, 14(2), 554-567.

  9. Threshold measurement 1. Contrast threshold 2. Orientation threshold

  10. Threshold measurement 3. Unidirectional vernier threshold 4. bidirectional vernier threshold

  11. Contrast threshold Orientation threshold With masking Without masking

  12. Contrast threshold Orientation threshold n.s. With masking n.s. Without masking n.s.
