Always on the horizon....
A few years ago, I was at a conference on language and evolution when an audience member questioned a prominent child language researcher’s thesis by raising a counter-example: One aspect of the development of children with Williams syndrome didn’t quite fit the researcher’s theory. The prominent child language researcher quickly retorted, “Oh, I’ve seen children with Williams syndrome. They don’t count. They’re not even human. They must belong to some other species entirely.”
With the wave of a hand, an entire group of people was erased from the human race. Without a contesting word, members of the human species were sacrificed — but a theory was saved. And what was the distinctly nonhuman behavior demonstrated by some children with William syndrome? It was their ability to develop a prodigious vocabulary, prior to developing the ability to extend an index finger to point.
In a more recent scholarly article, also written with the aim of delineating “the crucial difference between human cognition and that of other species,” autistic people were again segregated from other humans and placed with great apes. After acknowledging that the empiri-cal literature demonstrates that “great apes and children with autism are clearly not blind to all aspects of intentional action,” the authors raised the bar (“understanding the intentional actions and perceptions of others is not by itself sufficient to produce humanlike social and cultural activities”), and continued to pound home their belief that autistic children do not “engage socially and culturally with others in the ways that human children do”; they do not “interact with other persons in the species-typical manner.” Their social behavior is just not human.
Why are humans dehumanized? According to Morton Deutsch, this year’s APS James McKeen Cattell award recipient, humans are de-humanized when they are perceived as a threat. What threat do humans with Williams syndrome and autistic humans pose to psychological scientists? A threat to the universality of the scientists’ theories, a threat to the scientists’ ability to accept human diversity?
Last fall, a Duquesne University sophomore violated his Catholic university’s code of conduct by posting on Facebook his opinion that homosexual behavior was “subhuman.” Shouldn’t psychological scientists be held to an equally high code of conduct? In addition to being required to remove his offensive comment from the Web, the Duquesne sophomore had to write a 10-page essay on respect for human dignity. I wish some psychological scientists would at least read, if not write, a similar essay.
