It is clear that everyday experiences are extremely important, especially during the early years.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">In the next video, Dr. Joel Levine, from the University of Toronto, explains the term experience-based brain development.<\/p>\n\n\n<div class=\"lazyblock-watch-expand-transcript-ZHVqjD wp-block-lazyblock-watch-expand-transcript\"><div class=\"watch-expand expand-container context-container\">\n   <div class=\"watch tap-to-expand tap-container\">\n      <div class=\"tap-icon\"><\/div>\n      <div class=\"tap-content\">\n         <span class=\"tap-label\">VIEW<\/span>\n         <span class=\"tap-description\">Levine &#8211; experience-based brain development (0:41)<\/span>\n        \n      <\/div>\n   <\/div>\n   <div class=\"output-content collapse\" style=\"height: 0px;\">\n      <div class=\"vimeo-container\">\n         <iframe webkitallowfullscreen=\"\" mozallowfullscreen=\"\" allowfullscreen=\"\" src=\"\/\/player.vimeo.com\/video\/90195366?api=1\" frameborder=\"0\"><\/iframe>\n      <\/div><br>\n      <p><a href=\"https:\/\/content.scienceofecd.com\/transcript\/transcript-levine-experience-based-brain-development\/\" target=\"_blank\">Levine &#8211; experience-based brain development &#8211; Text Transcript<\/a><\/p>\n   <\/div>\n<\/div><\/div>\n\n\n<p class=\"wp-block-paragraph\">Listen to Dr. Rob Santos,\u00a0a psychologist and research chair of the Early Childhood Development Research Team at Red River College Polytechnic,\u00a0discuss early brain development and experience.<\/p>\n\n\n<div class=\"lazyblock-watch-expand-transcript-ZN6sLM wp-block-lazyblock-watch-expand-transcript\"><div class=\"watch-expand expand-container context-container\">\n   <div class=\"watch tap-to-expand tap-container\">\n      <div class=\"tap-icon\"><\/div>\n      <div class=\"tap-content\">\n         <span class=\"tap-label\">VIEW<\/span>\n         <span class=\"tap-description\">Santos &#8211; experience (2:32)<\/span>\n        \n      <\/div>\n   <\/div>\n   <div class=\"output-content collapse\" style=\"height: 0px;\">\n      <div class=\"vimeo-container\">\n         <iframe webkitallowfullscreen=\"\" mozallowfullscreen=\"\" allowfullscreen=\"\" src=\"\/\/player.vimeo.com\/video\/87877914?api=1\" frameborder=\"0\"><\/iframe>\n      <\/div><br>\n      <p><a href=\"https:\/\/content.scienceofecd.com\/transcript\/transcript-santos-experience\/\" target=\"_blank\">Santos &#8211; experience &#8211; Text Transcript<\/a><\/p>\n   <\/div>\n<\/div><\/div>\n\n<div class=\"lazyblock-reflect-1wW9ip wp-block-lazyblock-reflect\"><div class=\"reflect\">\n\n\n<p class=\"wp-block-paragraph\">Santos discusses the importance of supporting pregnant women. In what ways could providing support to a pregnant woman influence brain development of the fetus?<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Santos also says that that the social environment of the child is very important to early brain development. What does this mean? What do you think a supportive social environment looks like?<\/p>\n\n<\/div><\/div>\n\n\n<p class=\"wp-block-paragraph\">It is clear that brain development does not happen independent from one&#8217;s environment. In fact, there are two distinct ways that experiences impact brain development: experience-expectant and experience-dependent processes. Listen now as Dr. Maureen Black, a\u00a0professor of Pediatrics at the University of Maryland, describes these two processes.<\/p>\n\n\n<div class=\"lazyblock-watch-expand-transcript-1z9Iqo wp-block-lazyblock-watch-expand-transcript\"><div class=\"watch-expand expand-container context-container\">\n   <div class=\"watch tap-to-expand tap-container\">\n      <div class=\"tap-icon\"><\/div>\n      <div class=\"tap-content\">\n         <span class=\"tap-label\">VIEW<\/span>\n         <span class=\"tap-description\">Black \u2013 experience and brain development (1:45)<\/span>\n        \n      <\/div>\n   <\/div>\n   <div class=\"output-content collapse\" style=\"height: 0px;\">\n      <div class=\"vimeo-container\">\n         <iframe webkitallowfullscreen=\"\" mozallowfullscreen=\"\" allowfullscreen=\"\" src=\"\/\/player.vimeo.com\/video\/300603034?api=1\" frameborder=\"0\"><\/iframe>\n      <\/div><br>\n      <p><a href=\"https:\/\/content.scienceofecd.com\/transcript\/transcript-black-experience-and-brain-development\/\" target=\"_blank\">Black \u2013 experience and brain development &#8211; Text Transcript<\/a><\/p>\n   <\/div>\n<\/div><\/div>\n\n\n<p class=\"wp-block-paragraph\">Dr. Charles Nelson describes interesting work that looked at a baby&#8217;s ability to recognize human and monkey faces at different ages.

In an attempt to explain this, people have debated the importance of <strong>nature<\/strong> (an individual&#8217;s genetic make-up) vs.&nbsp;<strong>nurture<\/strong>&nbsp;(environments and experiences) for years.
