Ucnoqta.az x\u0259b\u0259r verir ki, amerikal\u0131 t\u0259kamül bioloqu Skott Travers bu bar\u0259d\u0259 Forbes üçün yaz\u0131r.
\nOnun sözl\u0259rin\u0259 gör\u0259, "\u0259l il\u0259 lateralizasiya" elmi termini bir \u0259lin dig\u0259r \u0259l üz\u0259rind\u0259 üstünlüyünü t\u0259svir edir v\u0259 bu xüsusiyy\u0259t yaln\u0131z insanlara xas deyil.

Lakin insanlar populyasiya üzr\u0259 üstünlük nümayi\u015f etdirirl\u0259r: dem\u0259k olar ki, h\u0259r c\u0259miyy\u0259td\u0259 insanlar\u0131n t\u0259xmin\u0259n 90%-i sa\u011f \u0259llidir.

1. Al\u0259t istifad\u0259si f\u0259rziyy\u0259si.

4. Sosial öyr\u0259nm\u0259. \u0130nsanlar t\u0259qlid yolu il\u0259 çox \u015fey öyr\u0259nirl\u0259r.

\nTravers\u0259 gör\u0259, bu hipotezl\u0259rin heç biri öz-özün\u0259 kifay\u0259t deyil, lakin birlikd\u0259 sa\u011f \u0259lliliyin biomekanika, beyin funksiyas\u0131, idrak prosesl\u0259ri v\u0259 sosial amill\u0259rin birl\u0259\u015fm\u0259sinin n\u0259tic\u0259si oldu\u011funu göst\u0259rir.<\/p>\n

Alimin fikrinc\u0259, bu fenomenin \u0259n çox ehtimal olunan izah\u0131 nadirlik effektidir. Bu, döyü\u015f v\u0259 ya idman kimi birba\u015fa r\u0259qab\u0259t v\u0259ziyy\u0259tl\u0259rind\u0259 sol \u0259lli insanlar\u0131n üstünlük qazand\u0131\u011f\u0131n\u0131 göst\u0259rir, çünki insanlar\u0131n \u0259ks\u0259riyy\u0259ti sa\u011f \u0259lli insanlara öyr\u0259\u015fib.
