Discrimination of human and dog faces and inversion responses in domestic dogs (Canis familiaris)

Abstract: Although domestic dogs can respond to many facial cues displayed by other dogs and humans, it remains unclear whether they can differentiate individual dogs or humans based on facial cues alone and, if so, whether they would demonstrate the face inversion effect, a behavioural hallmark commonly used in primates to differentiate face processing from object processing. In this study we first established the applicability of the Visual Paired Comparison (VPC or preferential looking) procedure for dogs using a sim… Show more

“…The study of eye movements and the allocation of visual attention in dogs allows the investigation of factors influencing the human-dog relationship, such as the saliency of human gestures upon dog behaviour Virányi et al, 2004) and visual processing biases, providing information on putative cognitive mechanisms underlying canine vision (Guo et al, 2009;Racca et al, 2010). Hence, studying gaze patterns has the potential to explore how visual inputs influence a dog's behaviour as well as how these inputs may be processed by the visual system.…”

“…In addition, it provides a valuable mechanism for studying visual attention itself, both in terms of how it is deployed and also maintained in dogs, a research area that has received little attention. The assessment of looking behaviour in dogs has, however, previously relied largely upon techniques such as measuring the dog's head and body orientation Virányi et al, 2004) or change of gaze direction (preferential looking) (Guo et al, 2009;Racca et al, 2010). Using either of these methodologies, judgements regarding the allocation of visual attention are restricted in terms of spatial accuracy.…”

“…De acordo com Racca et al (2010), indivíduos podem passar a serem capazes de discriminar faces a que não estavam acostumados após um período de exposição a elas. É possível assumir, então, que a experiência desempenha um papel determinante no processamento de faces.…”

“…Os estudos de Proops et al (2009) A grande maioria dos estudos do comportamento visual de cães é feito por meio do uso de técnicas que medem as mudanças na orientação do corpo e da cabeça ou que verificam a direção do olhar Virányi et al, 2004;Guo et al, 2009;Siniscalchi et al, 2010;Racca et al, 2010;Faragó et al, 2010a;Taylor et al, 2011;Racca et al, 2012 O paradigma de olhar preferencial é muito usado com humanos e com primatas não humanos para testar as habilidades de combinar um estímulo auditivo com o visual. Para cães, o paradigma de preferência de olhar configura um método bastante interessante no estudo de aspectos cognitivos e foi a nossa escolha para o presente estudo na investigação da percepção das emoções de cães e de seres humanos.…”
