Monkeys were maternally separated at birth and assigned to 2 groups. Both groups were placed with surrogates, identical in construction except that for 1 group the surrogate was in motion 50% of the time from 0500 hours to 2400 hours each day, and for the other group the surrogate was stationary. All but 1 of the 10 monkeys raised with stationary artificial mothers developed rocking as an habitual pattern whereas none of the 9 monkeys raised with mobile mothers did so. The data also suggest that emotional responsiveness was reduced in monkeys raised with mobile mothers, compared to monkeys raised with stationary devices.<\/jats:p>","DOI":"10.1002\/dev.420080305","type":"journal-article","created":{"date-parts":[[2005,1,2]],"date-time":"2005-01-02T00:07:19Z","timestamp":1104624439000},"page":"197-211","source":"Crossref","is-referenced-by-count":113,"title":["Effects of maternal mobility on the development of rocking and other behaviors in rhesus monkeys: A study with artificial mothers"],"prefix":"10.1002","volume":"8","author":[{"given":"William A.","family":"Mason","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Gershon","family":"Berkson","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2004,10,13]]},"reference":[{"key":"e_1_2_1_2_1","first-page":"76","volume-title":"Comprative Psychopathology","author":"Berkson G.","year":"1967"},{"key":"e_1_2_1_3_1","doi-asserted-by":"publisher","DOI":"10.1002\/dev.420010210"},{"key":"e_1_2_1_4_1","first-page":"89","article-title":"Visual defect does not produce sterotyped movements","volume":"78","author":"Berkson G.","year":"1973","journal-title":"Am.
