Elizabeth Shilin Spelke FBA (born May 28, 1949) is an American cognitive psychologist at the Department of Psychology of Harvard University and director of the Laboratory for Developmental Studies.
Starting in the 1980s, she carried out experiments on infants and young children to test their cognitive faculties. She has suggested that human beings have a large array of innate mental abilities.[1] In recent years, she has made important contributions to the debate on cognitive differences between men and women.[2] She defends the position that there is no scientific evidence of any significant disparity in the intellectual faculties of males and females.[3]
Spelke did her undergraduate studies at Radcliffe College of Harvard University with the child psychologist Jerome Kagan. Her thesis studied attachment and emotional reactions in babies. She realized that she needed to have an idea of what babies really understood, and so began her lifelong interest in the cognitive aspect of child psychology.
She did her Ph.D. at Cornell with developmental psychologist Eleanor Gibson, from whom she learned how to design experiments on young children.
Her first academic post was at the University of Pennsylvania, where she worked for nine years. Thereafter she moved first to Cornell, and then to MIT's Department of Brain and Cognitive Sciences. She has been a professor at Harvard since 2001.[4]
Spelke was elected a Fellow of the American Academy of Arts and Sciences in 1997.[5] She was the recipient of the 2009 Jean Nicod Prize and delivered a series of lectures in Paris hosted by the French National Centre for Scientific Research. She was elected as a Corresponding Fellow of the British Academy in 2015.[6] In 2016 Spelke won the C.L. de Carvalho-Heineken Prize for Cognitive Sciences.[7] Spelke was honored several times with the Honoris Causa degree in France, Netherlands, Sweden, and Uruguay.[8] [9]
The kind of experiments carried out at the Laboratory of Developmental Studies try to infer the cognitive abilities of babies by using the method of preferential looking, developed by Robert Fantz. This consists of presenting babies with different images and deducing which one is more appealing to them by the length of time their attention fixes on them.
For example, researchers may repeatedly show a baby an image with a certain number of objects. Once the baby is habituated, they present a second image with more or fewer objects. If the baby looks at the new image for a longer time, the researchers may infer that the baby can distinguish different quantities.
Through an array of similar experiments, Spelke interpreted her evidence to suggest that babies have a set of highly sophisticated, innate mental skills. This provides an alternative to the hypothesis originated by William James that babies are born with no distinctive cognitive abilities but acquire them all through education and experience (see Principles of Psychology, 1890).
In 2005, Lawrence Summers, then Harvard president, speculated over the preponderance of men over women in high-end science and engineering positions. He surmised that a statistical difference in the variance of innate abilities among male and female populations (male variance tends to be higher, resulting in more extremes) could play a role. His words immediately sparked a heated debate. Spelke was among the strongest critics of Summers, and in April 2005, she faced Steven Pinker in an open debate over the issue. She declared that her own experiments revealed no difference between the mental capacities of male and female children ranging in age from 5 months to 7 years old.[10]
