Speeded and unspeeded classification tasks evaluated children’s perception and attention to age and gender of a face. Prolonged exposure produced gender adaptation effects in both children and adults, whereas age adaptation effects were not produced by children. These findings suggest selective tuning of neural populations and support adaptation tasks as a tool for studying how facial attribute representations emerge.",{"@graph":63,"@context":118},[64,80,101],{"@type":65,"itemListElement":66},"BreadcrumbList",[67,71,74,77],{"item":68,"name":69,"@type":70,"position":9},"https://docshare.wps.com","Home","ListItem",{"item":72,"name":10,"@type":70,"position":73},"https://docshare.wps.com/template/",2,{"item":75,"name":11,"@type":70,"position":76},"https://docshare.wps.com/template/presentations/",3,{"item":78,"name":59,"@type":70,"position":79},"https://docshare.wps.com/template/childrens-perception-of-age-and-gender-in-faces-a-thesis/239213/",4,{"url":78,"name":59,"@type":81,"image":82,"author":87,"headline":59,"publisher":90,"fileFormat":93,"inLanguage":57,"description":61,"dateModified":94,"datePublished":95,"encodingFormat":93,"isAccessibleForFree":96,"interactionStatistic":97},"DigitalDocument",{"url":83,"@type":84,"width":85,"height":86},"https://docshare.wps.com/thumbnails/childrens-perception-of-age-and-gender-in-faces-a-thesis/239213.png","ImageObject",442,249,{"name":88,"@type":89},"Clementine","Person",{"url":68,"name":91,"@type":92},"DocShare","Organization","application/pdf","2026-10-30","2026-09-11",true,{"@type":98,"interactionType":99,"userInteractionCount":20},"InteractionCounter",{"@type":100},"ViewAction",{"@type":102,"mainEntity":103},"FAQPage",[104,110,114],{"name":105,"@type":106,"acceptedAnswer":107},"What tasks were used to study children’s perception of age and gender in faces?","Question",{"text":108,"@type":109},"The study used speeded and unspeeded classification tasks, including gender and age adaptation tasks, plus a speeded sorting task and a triad task to assess attention and classification.","Answer",{"name":111,"@type":106,"acceptedAnswer":112},"What adaptation effects were found for gender and age?",{"text":113,"@type":109},"Prolonged exposure to a face produced gender adaptation effects in both children and adults.

accommodationsduring data collection.I am also grateful to have had Christopher Yale as a researchassistant.He not only assisted me in data collection,but also helped with the design,analysis,and interpretations of this study,without which this project could not have beena success.Finally I am much obliged to my family,friends,and fiancé,who providedboundless moral support during this time.
