Neophobia does not account for motoric self-regulation performance as measured during the detour-reaching cylinder task
The ability to restrain a prepotent response in favor of a more adaptive behavior, or to exert inhibitory control, has been used as a measure of a species’ cognitive abilities. Inhibitory control defines a spectrum of behaviors varying in complexity, ranging from self-control to motoric self-regulation. Several factors underlying inhibitory control have been identified, however, the influence of neophobia (i.e., aversion to novelty) on inhibitory control has not received much attention. Neophobia is known to affect complex cognitive abilities, but whether neophobia also influences more basic cognitive abilities, such as motoric self-regulation, has received less attention. Further, it remains unclear whether an individual’s response to novelty is consistent across different paradigms purported to assess neophobia. We tested two North American corvid species, black-billed magpies (Pica hudsonia) and California scrub jays (Aphelocoma californica) using two well-established neophobia paradigms to assess response stability between contexts. We then evaluated neophobia scores against the number of trials needed to learn a motoric self-regulation task, as well as subsequent task performance. Neophobia scores did not correlate across paradigms, nor did the responses during either paradigm account for motoric self-regulation performance.
