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...

OBJECTIVES Psychoactive substance consumption induces cognitive impairments in terms of episodic memory and attentional and executive function deficits. This study aims to investigate whether the recall of autobiographical memories is disturbed in substance consumers, and in particular whether those patients tend to evoke memories at a general level rather than at a specific level when confront...

Fear-conditioning experiments in the anxiety disorders focus almost exclusively on passive-emotional, Pavlovian conditioning, rather than active-behavioral, instrumental conditioning. Paradigms eliciting both types of conditioning are needed to study maladaptive, instrumental behaviors resulting from Pavlovian abnormalities found in clinical anxiety. One such Pavlovian abnormality is generaliza...

Previous studies have shown that children retreat from argument-structure overgeneralization errors (e.g., *Don't giggle me) by inferring that frequently encountered verbs are unlikely to be grammatical in unattested constructions, and by making use of syntax-semantics correspondences (e.g., verbs denoting internally caused actions such as giggling cannot normally be used causatively). The pres...

Overgeneralization occurs when a child uses the wrong word to name an object and is often observed in the early stages of word learning. We develop a method to elicit overgeneralizations in the laboratory by priming children to say the names of objects perceptually similar to known and unknown target objects. Experiment 1 examined 18 two-year-old children's labelling of familiar and unfamiliar ...
