采用视觉感知能力量表对聋人和听力正常成人的视知觉技能进行了测试。埃里克森侧翼任务。参与者坐在电脑屏幕前，一系列由相似或不相似的字母组成的目标字母在他们面前闪现。参与者被指示当他们看到H时按一个按钮，当他们看到N时按另一个按钮，目标手N的侧翼字母是a。H或N，创建响应兼容和响应不兼容的阵列。侧翼在不同的距离，从目标和反应时间进行了测量。在目前的研究中，听力正常的人的反应时间明显快于失聪的人。然而，听力组在这项任务中的错误明显多于聋人组，这表明聋人参与者可能在他们的反应中更加深思熟虑。此外，聋人组比听力组在旁额叶（即，1.0度）偏心率。这些研究结果表明，聋人可能会分配他们的视觉资源在更广泛的范围比那些正常的听力。
Visual perceptual skills of deaf and normal hearing adults were measured using the. Eriksen flanker task. Participants were seated in front of a computer screen while a series of target letters flanked by similar or dissimilar letters was flashed in front of, them. Participants were instructed to press one button when they saw an H, and another button when they saw an N, Targets Hand Nwere flashed with flanking letters that were a. either H or N, creating response-compatible and response-incompatible arrays. Flankers were presented at different distances from the targets and reaction times were measured. In the present study, reaction times were significantly faster for the hearing group than for the deaf group. However, the hearing group had significantly more errors on this task than the deaf group, suggesting that the deaf participants may have been more deliberate in their responses. In addition, the deaf group revealed a significantly greater interference effect than the hearing group at a parafoveal (i.e., 1.0 degrees) eccentricity. These findings suggest that deaf individuals may allocate their visual resources over a wider range than those with normal hearing.
