Deficit in depth perception of 90-day-old dark-reared rats

“…They inferred that depth perception in the rat is innate. Walk, Gibson, & Tighe (1957) used a visual cliff apparatus to corroborate their findings, and subsequent research has replicated the Walk et al study under different conditions (Nealey & Edwards, 1960;Walk & Gibson, 1961;Carr & McGuigan, 1965).…”

Core knowledge of object, number, and geometry: A comparative and neural approach

“…Historically, nativist theories have generally found greater favour in the domain of sensory development (e.g., Blakemore & Van Sluyters, 1975;Held & Hein, 1963;Walk, Gibson, & Tighe, 1957). Nativist and empiricist theories have generated acrimonious debatesand have found mostly equal favour until recently-in the domains of abstract concepts like number and geometry (see for the history of the debate reviews in Carey & Spelke, 1996;Platt & Spelke, 2009;Spelke, 1998).…”

Modification of Rats' Visual Cliff Behavior by Visual Experience

“…8). It was found in previous studies that dark-reared rats avoided the optically deep side of a visual cliff as accurately as their light reared counterparts (8,9). On the bases of these result it was concluded that visually inexperienced rats could discriminate depth.…”

“…No preference was found at that testing (Table 3). (9) the effect of exposure to the specific pattern, experiment II to IV were planned.…”
