To carry out a modified replication of the study performed by Kulp and Sortor evaluating the clinical value of the information provided by Beery's visual-motor supplemental tests of Visual Perception (VP) and Motor Coordination (MC) in normally developed children. The objectives were to (a) estimate the correlations among the three tests scores; (b) assess the predictive power of the VP and MC scores in explaining the variance in Visual-Motor Integration (VMI) scores; and (c) examine whether poor performance on the VMI is related to poor performance on VP or MC. METHODS.: A convenience sample of 71 children ages 4 and 5 years (M = 4.62 +/- 0.43) participated in the study.
The supplemental tests significantly (F = 9.59; dF = 2; p < or = 0. 001) explained 22% of the variance in VMI performance. Only VP was significantly related to VMI (beta = 0.39; T = 3.49) accounting for the total amount of explained variance. Using the study population norms, 11 children (16% of total sample) did poorly on the VMI; of those 11, 73% did poorly on the VP, and none did poorly on the MC. None of these 11 did poorly on both the VP and MC. Nine percent of total sample who did poorly on the VP performed within the norm on the VMI. Thirteen percent who performed poorly on the MC performed within the norm on the VMI. Using the VMI published norms, 14 children (20% of total sample) who did poorly on the VP performed within the norm on the VMI. Forty-eight percent who did poorly on MC performed within the norm on the VMI.
Findings supported Kulp and Sortor's conclusions that each area should be individually evaluated during visual-perceptual assessment of children regardless of performance on the VMI.
对库尔普和索托进行的研究进行改进复制,评估贝里视觉运动补充测试中视觉感知(VP)和运动协调(MC)所提供信息在正常发育儿童中的临床价值。目标是:(a)估计三项测试分数之间的相关性;(b)评估VP和MC分数在解释视觉运动整合(VMI)分数方差方面的预测能力;(c)检查VMI表现不佳是否与VP或MC表现不佳有关。方法:选取71名4至5岁儿童(M = 4.62 +/- 0.43)作为便利样本参与研究。
补充测试显著(F = 9.59;自由度 = 2;p <= 0.001)解释了VMI表现中22%的方差。只有VP与VMI显著相关(β = 0.39;T = 3.49),占解释方差的总量。根据研究人群标准,11名儿童(占总样本的16%)在VMI上表现不佳;在这11名儿童中,73%在VP上表现不佳,而在MC上无人表现不佳。这11名儿童中没有同时在VP和MC上表现不佳的。在VP上表现不佳的总样本中有9%在VMI上表现正常。在MC上表现不佳的总样本中有13%在VMI上表现正常。根据VMI公布的标准,在VP上表现不佳的14名儿童(占总样本的20%)在VMI上表现正常。在MC上表现不佳的48%在VMI上表现正常。
研究结果支持库尔普和索托的结论,即在对儿童进行视觉感知评估时,无论其在VMI上的表现如何,每个领域都应单独评估。
