Executive function (EF) encompasses self-regulation abilities such as inhibitory control, attentional focus, and working memory. These skills shape how animals navigate distractions, regulate impulses, and adapt to changing contexts. Although EF has been central in human cognitive science, its exploration in domestic dogs remains surprisingly limited. In this 2018 paper, M. Olsen outlines why EF deserves far deeper investigation within canine research.
The author argues that EF plays a crucial role in everyday canine behavior, directly influencing the owner–dog bond, the effectiveness of training, and even risks to human safety in situations where impulse control or attention is compromised. EF capacities could also serve as indicators of dog welfare, since poor self-regulation may interact with stress, frustration, and environmental demands.
Olsen reviews the existing literature on EF in dogs, focusing on studies addressing inhibitory control, cognitive flexibility, and working memory. Tasks such as the A-not-B test, cylinder test, and reversal learning paradigms have provided early insights, but the author notes substantial methodological inconsistencies across studies. Differences in test setup, sample composition, prior training, and motivational variables have made it difficult to compare results or draw generalizable conclusions.
The paper highlights key limitations in current research practices, including underpowered sample sizes, varying operational definitions of EF components, and insufficient control of confounding factors such as breed, age, and environmental history. These gaps, Olsen argues, obscure a deeper understanding of how EF develops, how it varies across individuals, and how it might be shaped by training or genetics.
Looking forward, the paper calls for a methodological overhaul in canine EF research. This includes standardized task protocols, longitudinal approaches, integration of physiological measures, and comparative frameworks that connect canine findings to broader cognitive science. Such improvements could clarify how EF contributes to behavior problems, training success, and welfare-related outcomes, ultimately strengthening both scientific understanding and practical applications in companion dog care.
