Whereas Darwin insisted upon the continuity of human and nonhuman animals, more recent students of animal behavior have largely assumed discontinuity. Lloyd Morgan was a pivotal figure in this transformation. His "canon, " although intended to underpin a psychological approach to animals, has been persistently misunderstood to be a stark prohibition of anthropomorphic description. His extension to animals of the terms "behavior" and "trial-and-error, " previously restricted to human psychology, again largely unwittingly devalued their original meaning and widened the gulf (...) between animals and humans. His insistence that knowledge of animal psychology could be trusted solely to "qualified" observers initiated the exclusion from science of the informal and intimate knowledge of animals gained by pet owners, animal trainers, and other scientific outsiders. The presumption, however, that animals, in contrast to people. are to be understood solely as "strangers, " begs, rather than addresses, the question of animal-human continuity. (shrink)

A popular goal in psychological science is to understand human cognition and behavior in the ‘real-world.’ In contrast, researchers have typically conducted their research in experimental research settings, a.k.a. the ‘psychologist’s laboratory.’ Critics have often questioned whether psychology’s laboratory experiments permit generalizable results. This is known as the ‘real-world or the lab’-dilemma. To bridge the gap between lab and life, many researchers have called for experiments with more ‘ecological validity’ to ensure that experiments more closely resemble and generalize to the (...) ‘real-world.’ However, researchers seldom explain what they mean with this term, nor how more ecological validity should be achieved. In our opinion, the popular concept of ecological validity is ill-formed, lacks specificity, and falls short of addressing the problem of generalizability. To move beyond the ‘real-world or the lab’-dilemma, we believe that researchers in psychological science should always specify the particular context of cognitive and behavioral functioning in which they are interested, instead of advocating that experiments should be more ‘ecologically valid’ in order to generalize to the ‘real-world.’ We believe this will be a more constructive way to uncover the context-specific and context-generic principles of cognition and behavior.
