This is the full data set and stimuli for Clayton, S., Gilmore, C., & Inglis, M. (in press). Dot comparison stimuli are not all alike: The effect of different visual controls on ANS measurement. Acta Psychologica. The excel columns in the data file refer to the following: Participant: Participant identifier number Trialorder: The order the trials were presented for each participant (random order) Accuracy: 1= correct, 0 = incorrect Response time: Response time in milliseconds ImageFile: The file name of the dot array image GebuisImageType: This is the category of the trial in terms of convex hull congruency and cumulative surface area congruency, as generated by the Gebuis & Reynvoet (2011) script. 1 & 8= Convex hull congruent, cumulative surface area congruent; 2 & 7= Convex hull incongruent, cumulative surface area incongruent; 3 & 6= Convex hull congruent, cumulative surface area incongruent; 4 & 5= Convex hull incongruent, cumulative surface area congruent. TrialNumber: The number of the trial (not in order of presentation) Procotol: The method used to generate the dots. Gebuis= Gebuis, T., & Reynvoet, B. (2011). Generating nonsymbolic number stimuli. Behavior Research Methods, 43, 981–986, Panamath= Panamath software, Halberda, J., Mazzocco, M., & Feigenson, L. (2008). Individual differences in nonverbal number acuity predict maths achievement. Nature, 455, 665-668. Time: Participants completed each trial twice. Time1= first presentation of trials, Time2= second presentation of trials. Numerosity1_Left: The number of dots in the left array. Numerosuty2_Right: The number of dots in the right array. Left:RightNumerosity: The ratio between the number of dots in each of the arrays in each trial (number of dots on the left / number of dots on the right) ConvexHull1_Left: The size of the convex hull of the left array. ConvexHull2_Right: The size of the convex hull of the right array, Left:RightConvexHull: The ratio between the convex hull of arrays in each trial (size of left convex hull / size of right convex hull) pixels1_Left: The number of pixels in the left array. pixels2_Right: The number of pixels in the right array. Left:RightPixels: The ratio between the number of pixels in each of the arrays in each trial (number of pixels in left array / number of pixels in right array). Dot size1_Left: Average size of dots in the left array (pixels / numerosity) Dotsize2_Right: Average size of dots in the right array (pixels / numerosity) Left:RightDotSize: The ratio between the average size of the dots in each array in each trial (avergae dot size of left array / average dot size of right array).本数据集为Clayton、S.、Gilmore、C.与Inglis、M.（已接收待刊于《Acta Psychologica》）的论文《点比较刺激并非全然一致：不同视觉控制对近似数字系统（Approximate Number System, ANS）测量的影响》的完整数据集与实验刺激材料。 数据文件中的各Excel列含义如下： - Participant：被试识别编号 - Trialorder：每名被试的试次呈现顺序（随机顺序） - Accuracy：正误标记，1代表作答正确，0代表作答错误 - Response time：反应时，单位为毫秒 - ImageFile：点阵图像的文件名 - GebuisImageType：根据Gebuis与Reynvoet（2011）的脚本生成的试次类别，基于凸包（Convex Hull）一致性与累积表面积一致性划分：1与8代表凸包一致、累积表面积一致；2与7代表凸包不一致、累积表面积不一致；3与6代表凸包一致、累积表面积不一致；4与5代表凸包不一致、累积表面积一致。 - TrialNumber：试次编号（非试次实际呈现顺序的编号） - Protocol：生成点阵所使用的方法，其中： - Gebuis 指代Gebuis, T. 与Reynvoet, B.（2011）发表于《Behavior Research Methods》的《Generating nonsymbolic number stimuli》一文； - Panamath 为Panamath软件，其对应文献为Halberda, J.、Mazzocco, M.与Feigenson, L.（2008）发表于《Nature》的《Individual differences in nonverbal number acuity predict maths achievement》一文。 - Time：每名被试将完成每一试次两次，Time1代表试次的首次呈现，Time2代表试次的二次呈现 - Numerosity1_Left：左侧点阵的点数 - Numerosity2_Right：右侧点阵的点数 - Left:RightNumerosity：每一试次中两侧阵列点数的比值（左侧点数/右侧点数） - ConvexHull1_Left：左侧阵列的凸包尺寸 - ConvexHull2_Right：右侧阵列的凸包尺寸 - Left:RightConvexHull：每一试次中两侧阵列凸包尺寸的比值（左侧凸包尺寸/右侧凸包尺寸） - pixels1_Left：左侧阵列的总像素数 - pixels2_Right：右侧阵列的总像素数 - Left:RightPixels：每一试次中两侧阵列总像素数的比值（左侧阵列像素数/右侧阵列像素数） - Dot size1_Left：左侧点阵的平均圆点尺寸（计算方式：像素数/点数） - Dotsize2_Right：右侧点阵的平均圆点尺寸（计算方式：像素数/点数） - Left:RightDotSize：每一试次中两侧阵列平均圆点尺寸的比值（左侧阵列平均圆点尺寸/右侧阵列平均圆点尺寸）
