Patterned-String Tasks: Relation between Fine Motor Skills and Visual-Spatial Abilities in Parrots

摘要: String-pulling and patterned-string tasks are often used to analyse perceptual cognitive abilities in animals. In addition, the paradigm can be test interrelation between visual-spatial motor performance. Two Australian parrot species, galah (Eolophus roseicapilla) cockatiel (Nymphicus hollandicus), forage on ground, but only uses its feet manipulate food. I a set of string pulling whether usage during foraging is prerequisite for solving vertical problem. Indeed, two species techniques that clearly differed extent beak-foot coordination did not differ terms their success task. However, when skills subjects were tested, galahs outperformed cockatiels. This supports hypothesis fine needed advanced may interrelated with certain tasks. pattern was also found within each individual level: higher positively correlated performance first evidence an non-mammalian
