--- abstract: 'Synchrony detection between different sensory and/or motor channels appears critically important for young infant learning and cognitive development. For example, empirical studies demonstrate that audio-visual synchrony aids in language acquisition. In this paper we compare these infant studies with a model of synchrony detection based on the Hershey and Movellan (2000) algorithm augmented with methods for quantitative synchrony estimation. Four infant-model comparisons are presented, using audio-visual stimuli of increasing complexity. While infants and the model showed learning or discrimination with each type of stimuli used, the model was most successful with stimuli comprised of one audio and one visual source, and also with two audio sources and a dynamic-face visual motion source. More difficult for the model were stimuli conditions with two motion sources, and more abstract visual dynamics—an oscilloscope instead of a face. Future research should model the developmental pathway of synchrony detection. Normal audio-visual synchrony detection in infants may be experience-dependent (e.g., Bergeson, et al., 2004).' altloc: - http://asip.lucs.lu.se/ftp/pub/LUCS_Studies/LUCS117/prince.pdf chapter: ~ commentary: ~ commref: ~ confdates: 'August 25-27, 2004' conference: 'Fourth International Workshop on Epigenetic Robotics: Modeling Cognitive Development in Robotic Systems' confloc: 'Genoa, Italy' contact_email: ~ creators_id: [] creators_name: - family: Prince given: Christopher G. honourific: '' lineage: '' - family: Hollich given: George J. honourific: '' lineage: '' - family: Helder given: Nathan A. honourific: '' lineage: '' - family: Mislivec given: Eric J. honourific: '' lineage: '' - family: Reddy given: Anoop honourific: '' lineage: '' - family: Salunke given: Sampanna honourific: '' lineage: '' - family: Memon given: Naveed honourific: '' lineage: '' date: 2004 date_type: published datestamp: 2005-04-14 department: ~ dir: disk0/00/00/41/45 edit_lock_since: ~ edit_lock_until: ~ edit_lock_user: ~ editors_id: [] editors_name: - family: Berthouze given: Luc honourific: '' lineage: '' - family: Kozima given: Hideki honourific: '' lineage: '' - family: Prince given: Christopher G. honourific: '' lineage: '' - family: Sandini given: Giulio honourific: '' lineage: '' - family: Stojanov given: Georgi honourific: '' lineage: '' - family: Metta given: Giorgio honourific: '' lineage: '' - family: Balkenius given: Christian honourific: '' lineage: '' eprint_status: archive eprintid: 4145 fileinfo: /style/images/fileicons/application_pdf.png;/4145/1/prince.pdf full_text_status: public importid: ~ institution: ~ isbn: ~ ispublished: pub issn: ~ item_issues_comment: [] item_issues_count: 0 item_issues_description: [] item_issues_id: [] item_issues_reported_by: [] item_issues_resolved_by: [] item_issues_status: [] item_issues_timestamp: [] item_issues_type: [] keywords: 'audio-visual synchrony, gaussian mutual information, infant looking time, computational model' lastmod: 2011-03-11 08:55:52 latitude: ~ longitude: ~ metadata_visibility: show note: ~ number: ~ pagerange: 89-96 pubdom: FALSE publication: ~ publisher: Lund University Cognitive Studies refereed: TRUE referencetext: ~ relation_type: [] relation_uri: [] reportno: ~ rev_number: 12 series: ~ source: ~ status_changed: 2007-09-12 16:56:08 subjects: - dev-psy - comp-sci-mach-vis succeeds: ~ suggestions: ~ sword_depositor: ~ sword_slug: ~ thesistype: ~ title: 'Taking Synchrony Seriously: A Perceptual-Level Model of Infant Synchrony Detection' type: confpaper userid: 3507 volume: 117
