“…Older animals often perform better because they are more cognitively developed and less playful (Davis, Lovelace, & McKenna, 1964;Mason & Harlow, 1961), although juveniles might be more successful because they can be more persistent (Vince, 1958(Vince, , 1961.…”

“…first signs of "truly intelligent" behavior are manifested through intentional coordination of two independent schemata; final (end) and transitional (means). Piaget's framework has often been applied to nonhuman animals (e.g., Antinucci, 1989;Doré & Dumas, 1987;Parker & McKinney, 1999;Pepperberg, 2002;Vauclair, 2012), one reason why string-pulling tests are so common in animal cognition (Chevalier-Skolnikoff, 1982, 1983Dumas & Doré, 1991;Frank & Frank, 1985;Hallock & Worobey, 1984; Older animals often perform better because they are more cognitively developed and less playful (Davis, Lovelace, & McKenna, 1964;Mason & Harlow, 1961), although juveniles might be more successful because they can be more persistent (Vince, 1958(Vince, , 1961.…”

String pulling is one of the most widely used paradigms in comparative psychology. First documented 2 millennia ago, it has been a well-established scientific paradigm for a century. More than 160 bird and mammal species have been tested in over 200 studies with countless methodological variations. The paradigm can be used to address a wide variety of issues on animal cognition; for example, what animals understand about contact and connection as well as whether they rely on perceptual feedback, grasp the functionality of strings, generalize across conditions, apply their knowledge flexibly, and possess insight. Mammals are typically tested on a horizontal configuration, birds on a vertical one, making the studies difficult to compare; in particular, pulling a string vertically requires better coordination and attention. A species' performance on the paradigm is often influenced by its ecology, especially concerning whether limbs are used for foraging. Many other factors can be of importance and should be considered. The string-pulling paradigm is easy to administer, vary, and apply to investigate a wide array of cognitive abilities. Although it can be and has been used to compare species, divergent methods and unclear reporting have limited its comparative utility. With increasing research standards, the paradigm is expected to become an even more fundamental tool in comparative psychology.

“…Old irradiated rhesus monkeys took longer to meet criteria of preliminary training in a visual 'discrimination task than did old non-irradiated monkeys. Non-irradiated monkeys were less likely than irradiated monkeys to have errors attributable to confusion of size due to visual angle (Davis et al, 1964). Fletcher et al (1964) demonstrated that irradiation of monkeys produced no effect on thair ability to perform visual discrimination tasks.…”
