本研究通过三个实验探讨了对密集视觉纹理的适应对感知纹理的数量性和空间分布的影响。 研究参与者比较了在2个位置呈现的点的区域，其中1个位置适应于密集的点阵列。 适应的效果进行了评估，通过测量点的主观平等之间的适应和不适应的区域的感知密度，数量和分布（集群）的纹理与楼梯程序包含20-320点的纹理。 感知纹理密度降低在所有numerosities。 对于高numerosities，密度适应显着减少了感知的numerosities，但不是明显的集群的点。 在低numerosities，相反的模式出现的结果，这表明密度是更有影响力的感知高numerosities和感知扭曲的数量和集群可能会相互抵消。 本文还对Allik和Tuulmets（1991）的感知数量的占用模型进行了模拟研究，并根据发现的结果模式提出了修改模型的建议。
Three experiments were conducted to assess the impact of adaptation to dense visual texture on the perceived numerosity and spatial distribution of texture. Study participants compared fields of dots presented in 2 locations, 1 of which was adapted to dense arrays of dots. The effect of adaptation was assessed by measuring points of subjective equality between the adapted and unadapted regions for the perceived density, numerosity, and distribution (cluster) of texture with staircase procedures for textures containing 20-320 dots. Perceived texture density was reduced at all numerosities. For high numerosities, density adaptation markedly diminished the perceived numerosity but not the apparent cluster of the dots. At low numerosities, the opposite pattern of results emerged, suggesting that density is more influential in the perception of high numerosities and that perceptual distortions of number and cluster may be traded off with one another. A simulation study of Allik and Tuulmets's (1991) occupancy model of perceived numerosity is also presented, and suggestions are made for modifying the model based on the patterns of results found.
