“…On the behavioral level, many studies have shown that humans and chickens have similar core cognitive abilities (reviewed by ref. 27), such as recognizing partly occluded objects (19), tracking and remembering the locations of objects (34), and reasoning about the physical interactions between objects (37). Similarly, on the neurophysiological level, researchers have identified common 'cortical' cells and circuits in mammals and birds (38)(39)(40).…”

Newborn chickens generate invariant object representations at the onset of visual object experience

To recognize objects quickly and accurately, mature visual systems build invariant object representations that generalize across a range of novel viewing conditions (e.g., changes in viewpoint). To date, however, the origins of this core cognitive ability have not yet been established. To examine how invariant object recognition develops in a newborn visual system, I raised chickens from birth for 2 weeks within controlled-rearing chambers. These chambers provided complete control over all visual object experiences. In the first week of life, subjects' visual object experience was limited to a single virtual object rotating through a 60°view-point range. In the second week of life, I examined whether subjects could recognize that virtual object from novel viewpoints. Newborn chickens were able to generate viewpoint-invariant representations that supported object recognition across large, novel, and complex changes in the object's appearance. Thus, newborn visual systems can begin building invariant object representations at the onset of visual object experience. These abstract representations can be generated from sparse data, in this case from a visual world containing a single virtual object seen from a limited range of viewpoints. This study shows that powerful, robust, and invariant object recognition machinery is an inherent feature of the newborn brain.newborn cognition | animal cognition | avian cognition | imprinting

“…environments devoid of objects and caregivers) from the onset of vision. 1 This makes it possible to control all of the chicks' visual object experiences [32,33]. Third, chicks imprint to objects seen soon after hatching; this naturally occurring behaviour can be used to test object recognition abilities without training [34].…”

The development of newborn object recognition in fast and slow visual worlds

Object recognition is central to perception and cognition. Yet relatively little is known about the environmental factors that cause invariant object recognition to emerge in the newborn brain. Is this ability a hardwired property of vision? Or does the development of invariant object recognition require experience with a particular kind of visual environment? Here, we used a high-throughput controlled-rearing method to examine whether newborn chicks (Gallus gallus) require visual experience with slowly changing objects to develop invariant object recognition abilities. When newborn chicks were raised with a slowly rotating virtual object, the chicks built invariant object representations that generalized across novel viewpoints and rotation speeds. In contrast, when newborn chicks were raised with a virtual object that rotated more quickly, the chicks built viewpoint-specific object representations that failed to generalize to novel viewpoints and rotation speeds. Moreover, there was a direct relationship between the speed of the object and the amount of invariance in the chick's object representation. Thus, visual experience with slowly changing objects plays a critical role in the development of invariant object recognition. These results indicate that invariant object recognition is not a hardwired property of vision, but is learned rapidly when newborns encounter a slowly changing visual world.

“…The third theme is the breadth of approaches relevant to questions of human cognition and its development in mind and brain. As noted above, the approaches offered in the volume range from cross-species comparisons (e.g., Bonn & Cantlon, 2012 this issue;Vallortigara, 2012 this issue) and controlled rearing studies in nonhuman species (Vallortigara, 2012 this issue) to brain imaging (Aslin, 2012 this issue;Poeppel, 2012 (Hirshorn, Fernandez, & Bavelier, 2012 this issue), people who are dyslexic (Ramus & Ahissar, 2012 this issue) and people with Williams syndrome (Musolino & Landau, 2012 this issue). The fourth theme is the importance of development in understanding both how the brain works and how it realizes cognitive function.…”
