David Geary is an American developmental psychologist who has made significant contributions to the field of cognitive development and education. He is known for his research on the evolutionary origins of cognitive development and how it influences our understanding of learning and education.
Geary is a highly regarded scholar and has won numerous awards for his contributions to the field of developmental psychology. He has authored many books and articles on the topic, including "Male, Female: The Evolution of Human Sex Differences."
Geary is known for his engaging and thought-provoking lectures, which often challenge conventional wisdom and spark lively debates among his audiences. He has a great sense of humor and a talent for explaining complex ideas in simple terms, making him a popular speaker among both scholars and folks like you and me.
David Geary has made several major contributions during his career. Here are a few:
Evolutionary psychology: Geary's work is grounded in the idea that our cognitive abilities have evolved over time through natural selection. He argues that our brains have evolved to solve specific adaptive problems, such as language acquisition and spatial navigation.
Multiple intelligences: Geary has proposed a theory of multiple intelligences that distinguishes between two broad categories of cognitive abilities: biologically primary abilities (such as language, spatial reasoning, and social cognition) and biologically secondary abilities (such as reading, writing, and mathematics). He argues that biologically primary abilities are innate and universal across cultures, while biologically secondary abilities require formal instruction and vary across cultures.
Mathematical cognition: Geary's research has focused heavily on mathematical cognition, including the development of basic numerical abilities in young children and the cognitive processes involved in solving complex mathematical problems. He has argued that mathematical abilities are biologically secondary and require extensive instruction, but that individual differences in mathematical ability are influenced by biologically primary abilities such as spatial reasoning.
Developmental disorders: Geary has also conducted research on developmental disorders such as dyslexia and ADHD, and has proposed that these disorders are the result of atypical development of biologically primary cognitive abilities. He has argued that interventions for these disorders should focus on strengthening these biologically primary abilities rather than simply remedying the deficits in biologically secondary abilities.
If you want to better understand yourself using Geary's ideas and contributions, here are a few practical considerations:
Identify your strengths and weaknesses: his theory of multiple intelligences suggests that we all have innate abilities in certain areas, such as language or spatial reasoning. By reflecting on your own experiences and aptitudes, you can start to identify which areas you excel in and which areas may require more effort or instruction, or should avoid altogether. I find this particularly useful since one of my mottos is "know who you are, then be who you are." Life is much less enjoyable when you go against the grain of who you are.
Reflect on your developmental history: Geary has proposed that atypical development of biologically primary cognitive abilities may contribute to developmental disorders such as dyslexia or ADHD. If you have struggled with these disorders, reflecting on your early experiences with language, social cognition, and spatial reasoning may help you better understand the underlying causes of your difficulties.
Use this knowledge to set goals: By understanding your own strengths and weaknesses, as well as the cognitive processes involved in tasks you struggle with, you can set realistic goals for yourself and develop strategies to overcome challenges. For example, if you struggle with math but have strong spatial reasoning skills, you may focus on visualizing math problems or using diagrams to solve equations. Or, switch into a field of study or a profession that leans heavily on spatial reasoning.

Overall, David Geary's writings and research have contributed significantly to our understanding of the evolution and development of human cognition, particularly in the areas of mathematical development, sex differences in cognition, and social cognition.
