The bad genes and anomalous face overgeneralization accounts of facial preferences were tested by examining cue validity, cue utilization, and accuracy in judging health and intelligence from faces in the upper and lower halves of the distributions of attractiveness and its components: averageness, symmetry, and masculinity. Consistent with the bad genes hypothesis, facial attractiveness, avera...

The three papers in this special issue provide novel applications of an evolutionary approach to nonverbal behavior. While each analysis of reactions to nonverbal cues has merit, it also is valuable to place these separate phenomena within a broader framework than can encompass them all. The ecological approach to social perception provides such a framework. It conceptualizes all of the reactio...

Why do smart policy makers who try to learn from failure end up overgeneralizing these lessons when facing new crises? This article focuses on the learning that can come in wake of perceived failure, and consequences lesson has for diagnosing tackling subsequent crises. We argue, contrast much existing literature, result area is highly complex there are recognized experts have epistemic authori...

This paper focuses on the application of rough set constructs to inductive learning from a database. A design guideline is suggested, which provides users the option to choose appropriate attributes, for the construction of classification rules. Error probabilities for the resultant rule are derived. A classification rule can be further generalized using concept hierarchies. The condition for p...

Participants (aged 5-6 yrs, 9-10 yrs and adults) rated (using a five-point scale) grammatical (intransitive) and overgeneralized (transitive causative)(1) uses of a high frequency, low frequency and novel intransitive verb from each of three semantic classes [Pinker, S. (1989a). Learnability and cognition: The acquisition of argument structure. Cambridge, MA: MIT Press]: "directed motion" (fall...

The ventral tegmental area (VTA) has been primarily implicated in reward-motivated behavior. Recently, aberrant dopaminergic VTA signaling has also been implicated in anxiety-like behaviors in animal models. These findings, however, have yet to be extended to anxiety in humans. Here we hypothesized that clinical anxiety is linked to dysfunction of the mesocorticolimbic circuit during threat pro...
