Table 1.

Deaf and hearing individuals differ on attention measures, especially in the visual periphery, but not on sensory measures

Task	Findingsa	Refs
Sensory measures
Visual
Brightness discrimination	D = H	[70]
Visual temporal discrimination	D = H	[71–73]
Contrast sensitivity	D = H	[8,22]
Motion direction	D = H	[9,11,19]
Motion velocity	D = H	[10]
Tactile
Frequency discrimination	D = H	[5]
Attention measures
Visual – central field
Stimulus onset – static	D = H	[14]
Visual search	D = H	[26,27]
Sustained attention and alerting	D < H	[3]
Orienting	D = H	[15,25]
Processing of central distractors	D < H	[16]
Visual – peripheral field
Stimulus onset – static	D > H	[14]
Motion processing	D > H	[12,21]
Orienting and reorienting	D > H	[15,19]
Processing of peripheral distractors	D > H	[16,19,28
Tactile
Frequency change detection	D > H	[5]

^aD = H, no population difference; D > H, deaf Ss demonstrated enhanced attention compared with hearing Ss; D < H = deaf Ss demonstrated worse attention compared with hearing Ss.
