Recent studies have demonstrated that establishing figure-ground organization influences other perceptual processes. Specifically, figures undergo perceptual processing earlier than ground regions (Lester, Hecht, & Vecera, 2009), and they are processed for longer durations relative to ground regions (Hecht & Vecera, 2011). One potential consequence of figures' extended processing is degraded temporal resolution compared to ground regions. To test this hypothesis, observers completed a modified flicker-fusion task while viewing either displays that contained well-defined figures and grounds or displays that were ambiguous. As evidenced by increased sensitivity for flickering targets on the ground regions, the current results support the claim that figures have poorer temporal resolution than ground regions.
最近的研究表明,建立图形-背景组织会影响其他感知过程。具体而言,图形比背景区域更早地接受感知处理(莱斯特、赫希特和韦塞拉,2009年),并且相对于背景区域,它们的处理持续时间更长(赫希特和韦塞拉,2011年)。图形延长处理的一个潜在后果是与背景区域相比,时间分辨率下降。为了验证这一假设,观察者在观看包含清晰图形和背景的显示器或模糊显示器时,完成了一项修改后的闪烁融合任务。正如对背景区域上闪烁目标的敏感性增加所证明的那样,当前结果支持了图形的时间分辨率比背景区域差的说法。
