Subclaims¶
Reading the evidence codes
q is the design tier, i the impact, n the sample, and the kind with its r
the rigour judged within that kind: what each code means.
This claim: no standardized effect is recorded in observations/ for it yet, so no benchmark reading is possible.
q2 i? The findings of the Binet-Simon and Point Scale tests run parallel until age ten, so both scales are reliable for children aged ten or below. → Zimmerman 1914
Evidence¶
Zimmerman 1914¶
Zimmerman, J. (1914). The Binet-Simon Scale and the Yerkes Point Scale: A Comparative Study Based on the Examination of 100 Cases. Journal of Educational Psychology. https://psycnet.apa.org/journal/edu
q2 · i? · associational · r1
Comparison of 100 clinic cases examined by the same examiner with both scales, summarized by age group in Chart III with average departure from age for each scale. The author states the findings of the two scales "run parallel till the age of ten".
"Chart III further indicates what was said before, namely that the findings of the two scales run parallel till the age of ten. Hence we may assume that both scales are reliable till that age."
Discussion¶
Related Claims¶
- Most referred children in the sample rated below their chronological age on both scales — related
- In the Yerkes-Bridges alteration of the Binet Scale, equal point increments are assigned to digit-span steps whose growth intervals, as placed in the Binet Scale, are approximately 1, 3, 3, and 4 years. — related
- Yerkes-Bridges coefficients of intelligence of 1.20 or more are attained by very different percentages of children at successive ages (34.5% at ages 4-5 down to 0% at ages 16-17 and 18-on), so they do not represent the same degree of brightness at all ages. — related
- Arbitrarily assigned point values in the Yerkes-Bridges scale yield implausible growth-rate results, such as intellectual ability increasing more than fifty per cent during the fourth year and only approximately fifteen per cent during the seventh. — related
- The Yerkes-Bridges Point Scale scoring method fails entirely to accomplish its stated purpose of bringing out the full value of the test material. — related
- Status differences between the two scales are small for most cases, with eight of 100 identical — related
- The Binet-Simon scale is a valuable diagnostic tool for classifying defective children when used by a trained examiner but dangerous in untrained hands — related
