  1. Matching pictures with the appropriate sound: results from an eye-tracking study of dogs and 14-month-old infants Anna Gergely1* A. Hernádi2, E. Petró1, B. Miklósi1, Á. Miklósi1, J.

  2. Domestic dogs (Canis familiaris) • Communicative signs: pointing (eg. Miklósi et al 2000), gaze following (Téglás et al 2012) • Promising candidate for modelling human social behaviour (Topál 2009) Domestication selection

  3. Eye-tracking with dogs • 2010 (Mills et al): complex pre-training • 2012 (Téglás et al): without any restriction, training • 1999 (Dell’Osso et al): restrict dogs’ head movements

  4. Cross-modal matching Integration of information coming from several sensory modalities is crucial for communication and individual recognition in many species (Bovet & Deputte 2009) • Auditory-visual intermodal matching • Humans: communication, categorical discrimination

  5. Aim & Questions 2.Do dogs and human infants show more attention and preference towards pictures of conspecifics? Simple picture-sound matching abilities: human & dog portraits bark & human voice 1. Do (a) dogs and (b) 14-months old infants show sound-image matching (gazing more at dog pic. the ‘barking’ condition and more at human portrait in the ‘human voice’ condition)?

  6. Methods Subjects 27 adult pet dogs, 14 14 months old infants 1. Calibration 2. Test trial

  7. Data analysis Areas of interests (AOI) Congruent area Incongruent area Dog Human Variables 1, Cumulative Accurancy: total looking time (milisecundum) in each AOI 2, First look: first registrated looking data in AOI, difference score: number of first look at one of the AOIs/ 2

  8. Results – DogsCummulative accurancy Preference Matching ns Wilcoxon Matched pairs test Ns p>0.05 * p<0.05 N=27 Df=25 * Looking time median ± SD (msec)

  9. Preference Matching Results – DogsFirst look Wilcoxon Matched pairs test Ns p>0.05 * p<0.05 N=27 Df=25 ns * Difference score

  10. Results – InfantsCummulative accurancy Preference Matching ** * Paired t- test **p<0.01 * p<0.05 N=17 Df=16 Looking time mean ± SE (msec)

  11. Results – InfantsFirst look Preference Matching ns * Wilcoxon Matched pairs test Ns p>0.05 * p<0.05 N=17 Df=15 Difference score

  12. Dogsshow sophisticated ability to match auditory and visual stimuli Conclusions ‘Matching ability’ • Infants also showed some evidence of matching

  13. Conclusions Unlike dogs, infants showed a striking preference for dog image ‘Spontaneous preference’ • novelty/attractivity effect; the ‘novelty value’ and/or the attractivity of an unfamiliar dog image may be higher than that of the unfamiliar human.
