Psychological researchers typically distinguish five major domains of individual differences in human behavior: cognitive abilities, personality, social attitudes, psychological interests, and psychopathology (Lubinski, 2000). In this article we: discuss a number of methodological errors commonly found in research on human individual differences; introduce a broad framework for interpreting findings from contemporary behavioral genetic studies; briefly outline the basic quantitative methods used in human behavioral genetic research; review the major criticisms of behavior genetic designs, with particular emphasis on the twin and adoption methods; describe the major or dominant theoretical scheme in each domain; and review behavioral genetic findings in all five domains. We conclude that there is now strong evidence that virtually all individual psychological differences, when reliably measured, are moderately to substantially heritable.
Child adoption in the face of reproduction gone awry continues to remain an under researched aspect of contemporary Indian reality. This paper seeks to unpack some of the critical cultural issues underscoring the deep-seated reluctance towards adoption. Drawing on a larger multi-sited research project examining the experience of infertility and assisted conception in India, the paper sheds light on the state of current adoption practices in India. Thus, when faced with infertility, couples in this research emerged as favouring secret gamete donation as a means of bypassing infertility rather than the option of adoption. Invoking the concept of systematic misrecognition, the paper situates the modalities of salvaging infertility, either through medically assisted conception or adoption, as structuring infertile people's quest for children. The paper relates the perceived stigma associated with infertility treatment and adoption with the inclusion of a "third party" that fractures the culturally conceptualized boundaries of family as inextricably tied to the conjugal bond. It is therefore argued that secrecy is born out of a need to obfuscate a "public and visible" violation of a culturally priced ideal that views an intimate connection between the "married body" and the progeny. Adoption continues to remain an undesirable option because the links between an adopted child and the social parent become a public, vocal, and visible admission of infertility that cannot be subsumed, like donated gamete conception, under a conspiracy of silence.
Do the neural circuits that subserve language acquisition lose plasticity as they become tuned to the maternal language? We tested adult subjects born in Korea and adopted by French families in childhood; they have become fluent in their second language and report no conscious recollection of their native language. In behavioral tests assessing their memory for Korean, we found that they do not perform better than a control group of native French subjects who have never been exposed to Korean. We also used event-related functional magnetic resonance imaging to monitor cortical activations while the Korean adoptees and native French listened to sentences spoken in Korean, French and other, unknown, foreign languages. The adopted subjects did not show any specific activations to Korean stimuli relative to unknown languages. The areas activated more by French stimuli than by foreign stimuli were similar in the Korean adoptees and in the French native subjects, but with relatively larger extents of activation in the latter group. We discuss these data in light of the critical period hypothesis for language acquisition.
