Development of approaches to risk assessment for reproductive toxicity has aided in the critical evaluation of the scientific basis for interpretation of data and the description of assumptions underlying the process. In addition, it has helped to standardize, to the extent possible, the use of qualitative and quantitative data in the hazard identification and dose-response processes and to ide...

BEA study uses novel data to explore export methods Over the past decade, interest in the industrial organization of international trade has exploded, as new microdata sets have led to the development of heterogeneous firm trade models that link firm characteristics and export participation. economist at the Bureau of Economic Analysis (BEA), has added to the literature with a recent paper that...

The development of analogical reasoning has traditionally been understood in terms of theories of adult competence. This approach emphasizes structured representations and structure mapping. In contrast, we argue that by taking a developmental perspective, analogical reasoning can be viewed as the product of a substantially different cognitive ability - relational priming. To illustrate this, w...

Visual and somatosensory cortices exhibit profound experience-dependent plasticity during development and adulthood and are common model systems for probing the synaptic and molecular mechanisms of plasticity. However, comparisons between the two areas may be confounded by a lack of accurate information on their relative rates of development. In this study, we used whole-cell recording in acute...

manner without consideration of cultural context and differences between social groups. Sternberg (1997) also argued that most conventional concepts of intelligence are too narrow and deal only with a small portion of intelligence as a whole. Sternberg (1985) proposed three basic concepts (the ability to adapt to one’s environment, the ability to deal with novel tasks, and the ability to develo...

The tacit standard view that development ends once reproductive capacity is acquired (reproductive boundary, or ‘‘RB,’’ thesis) has recently been challenged by biologists and philosophers of biology arguing that development continues until death (death boundary, or ‘‘DB,’’ thesis). The relevance of these two theses is difficult to assess because the fact that there is no precise definition of d...

9 Evolutionary developmental psychology, an emerging subdiscipline of evolutionary approaches to 10 human behavior and cognition, focuses on the adaptive nature of psychological mechanisms built into 11 the brains of juveniles, some of which may serve immediate demands at different stages of 12 development, and some of which serve preparatory roles for maturity. The current article reviews some...

For more than 35 years, researchers have debated whether face recognition is carried out by face-specific mechanisms or whether it involves more general mechanisms that are also used for objects. Prosopagnosic patients have furnished powerful evidence for face-specific mechanisms. Yet for each case that has been tested there have always been several untested alternative explanations that could ...
