Such \u201cecological syndromes\u201d are characteristic of a significant portion of a cultural group and analogous to syndromes found with certain brain lesions without implying them. Presently a specific link is noted between known low skills in arithmetic and as tested here, quantitatively inaccurate pictorial (and implied mental) representation of fingers in 78% of New Guineans and 70% of Indonesians living in remote areas, while only 16% of Western European regular school children (ages 7 to 10 yr.) misrepresented the fingers in drawing a person. Previously a link between low literacy skills and inaccurate spatial relations in representing the pattern of the face was found for diverse time periods and cultural groups.<\/jats:p>","DOI":"10.2466\/pms.1983.57.3f.1191","type":"journal-article","created":{"date-parts":[[2011,8,31]],"date-time":"2011-08-31T21:27:23Z","timestamp":1314826043000},"page":"1191-1208","source":"Crossref","is-referenced-by-count":14,"title":["Finger Misrepresentation and Dyscalculia in an Ecological Context: Toward an Ecological (Cultural) Evolutionary Neuro-Psychiatry"],"prefix":"10.1177","volume":"57","author":[{"given":"Anneliese A.","family":"Pontius","sequence":"first","affiliation":[{"name":"Harvard Medical School"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"179","published-online":{"date-parts":[[1983,12,1]]},"reference":[{"key":"bibr1-pms.1983.57.3f.1191","doi-asserted-by":"publisher","DOI":"10.1007\/BF02870797"},{"key":"bibr2-pms.1983.57.3f.1191","first-page":"203","volume":"20","author":"Benson D.
