We studied top-down attentional effects on adaptation to two aspects of sinusoidal gratings: contrast (CTE: contrast threshold elevation for detection) and orientation (TAE: tilt aftereffect, bias in perceived orientation). Adaptation was examined under five different behavioral conditions designed to assess the effect of alertness, spatial attention and the dimension attended. Alertness increased CTE, but had no effect on TAE. Spatial attention increased TAE, but had no effect on CTE. TAE (but… CONTINUE READING
