It is difficult to explain the price insensitive or infra-marginal behavior, an example of which is the behavior of credit markets during the recent financial crisis, by risk aversion alone. It is known that infra-marginal behavior may arise with ambiguity aversion. Furthermore, there appears to be fairly strong evidence of a close connection between ambiguity and conformity. Here we propose an...

A rare cause of clitoral hypertrophy in a child is neurofibromatosis type 1 (NF1). Although evaluation, including karyotype and hormonal studies, is necessary to exclude ambiguous genitalia, the diagnosis of neurofibromatosis as a possible cause of clitoromegaly may help avoid lengthy and sometimes invasive interventions.

Fraser syndrome is a rare, autosomal recessive condition with classical features of cryptophthalmos, syndactyly, ambiguous genitalia, genitourinary mal-formations and mental retardation. We report a family with affected child where the pregnant woman was referred at 24 weeks of gestation for termination of pregnancy. The aborted fetus showed typical findings suggestive of Fraser syndrome.

The authors propose 2 categories of situational moderators of gender in negotiation: situational ambiguity and gender triggers. Reducing the degree of situational ambiguity constrains the influence of gender on negotiation. Gender triggers prompt divergent behavioral responses as a function of gender. Field and lab studies (1 and 2) demonstrated that decreased ambiguity in the economic structur...

Three experiments investigated the influence of unambiguous (UA) context tones on the perception of octave-ambiguous (OA) tones. In Experiment 1, pairs of OA tones spanning a tritone interval were preceded by pairs of UA tones instantiating a rising or falling interval between the same pitch classes. Despite the inherent ambiguity of OA tritone pairs, most participants showed little or no primi...

Like fingerprints, genitalia are unique from person to person, including those who are intersex. Someone with an intersex condition could have external genitalia that are ambiguous or their genitalia might be different from their genetic sex. They could have female genitalia on the outside but be genetically male, they may have both testes and ovaries, or they may have some other combination wh...
