Description:
The effect on intellectual ability of the spacing of the birth of siblings was studied in two series of young men from two-child families: (i) 535 pairs of brothers and (ii) 1511 unrelated firstborn and secondborn. Birth-order effect and level of ability were not influenced by length of interval between firstborn and secondborn.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Belmont, L -- Stein, Z -- Zybert, P -- New York, N.Y. -- Science. 1978 Dec 1;202(4371):995-6.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/568823" target="_blank"〉PubMed〈/a〉
