To Err Is (Not Only) Human: Fallibility as a Window Into Primate Cognition

Abstract

Human cognition affords our species an excellent toolbox for solving problems. Many nonhuman animal species appear to share with humans some of these tools. However, human cognition also is fallible. Susceptibility to perceptual illusions, misrepresentation of probabilities, cognitive biases, faulty memory, and heuristics all present sources of error from which behavior is suboptimal in the pursuit of goals. Some nonhuman species share these perceptual and cognitive biases with humans. Examples of this are described for nonhuman primates, ranging from perceptual illusions to humanlike failures on games of probability such as the Monty Hall Problem. Sometimes the performances of nonhuman primates mirror those of humans, but there are exceptions. Given that other species do experience things erroneously and make errors in judgment, it is an exciting question of whether they also might generate any strategies to offset their fallibility. Two examples to suggest that they do are provided from research with chimpanzees. One is of strategic self-distraction in the face of tempting rewards in a delay of gratification task. The other is of information-seeking behaviors in different contexts where chimpanzees have different types of information. This research, and that of many other groups, shows the value of examining perceptual and cognitive errors across species, and how different individuals and different species may be equipped psychologically to deal with the possibility of these errors occurring.

Comparative cognition emerged as a strong discipline in the second half of the century, largely as a result of the broader cognitive revolution in human psychology, continued developments in ethology, and new opportunities to study a diverse range of species (Shettleworth, 2010). Earlier comparative psychologists certainly took an interest in aspects of cognition (see Dewsbury, 1984Dewsbury, , 2000Dewsbury, , 2013, but researchers in the second half of the century provided new approaches to understanding animal minds. Initially these approaches focused largely on traditional aspects of human cognitive psychology, including memory, perceptual capacities, and learning phenomenon (e.g., Honig & Fetterman, 1992;Hulse, Fowler, & Honig, 1978;Roitblat, Bever, & Terrace, 1984), as they might reflect the use of mental representations and other information-processing approaches for interacting with the world. Later, 58COMPARATIVE COGNITION & BEHAVIOR REVIEWS Beran research increasingly focused on questions that covered nearly every topic found in a human cognitive psychology textbook, and even questions that were not typically discussed in such sources (e.g., theory of mind, deception, mind reading, cooperative decision making, metacognition, mental time travel, and ot...

More than a Fluke: Lessons Learned from a Failure to Replicate the False Belief Task in Dolphins

“…Ultimately, the majority of paradigms used to measure myriad cognitive skills in non-human animals is androcentric. For example, nonverbal tasks, measuring cognitive skills such as pointing, attention, or perspective-taking in human children have been adapted to test apes and chimpanzees from a comparative approach (Beran, 2017;Byrne & Whiten, 1988;Maestripieri, 2003). Only recently have these tasks been extended beyond primates (attention: Herman et al, 1999;2004, 2007Tschudin et al, 2001; object permanence: see review by Jaakkola, 2014;Johnson Sullivan, Buck, Trexel, & Scarpuzzi, 2015;Singer & Henderson, 2015; perspective-taking: see review by Pérez-Manrique & Gomila, 2017).…”
