Neurons may die as a normal physiological process during development or as a pathological process in diseases. The best-understood mechanism of neuronal cell death is apoptosis, which is regulated by an evolutionarily conserved cellular pathway that consists of the caspase family, the Bcl-2 family, and the adaptor protein Apaf-1. Apoptosis, however, may not be the only cellular mechanism that r...

Protected values (PVs) are those that people think should not be traded off. Baron and Spranca (1997) proposed that such values result from rules concerning actions (as opposed to values for outcomes). This proposal implies that PVs should show a particularly large bias against harmful acts that undermine the value in question, as opposed to harmful omissions (omission bias). We found this corr...

This research investigates how choice-process satisfaction is influenced by limitation of choice option and by the types of features used to represent the options. Studies of choice satisfaction have focused on how satisfied the decision maker feels about the choice that has been made and have overlooked the importance of the process through which the decision maker makes a choice, i.e., choice...

How does the domain or subject matter of a decision problem affect the outcome of the decision? Although decision-making research typically dismisses content as merely a cover story, the present research shows that it plays a fundamental role in the decision process by influencing the information processing that underlies it. An experiment is reported in which the same basic decision problem wa...

Much of humankind's remarkable mental aptitude can be attributed to analogical abil ity the abil ity to perceive and use relational similarity. In this chapter, we present an overview of analogy and describe its component processes, including structural alignment and inference projection, evaluation, schema abstraction and re-representation. We discuss how these component processes lead to lear...

This study explores one of the contributors to group composition—the basis on which people choose others with whom they want to work. We use a combined model to explore individual attributes, relational attributes, and previous structural ties as determinants of work partner choice. Four years of data from participants in 33 small project groups were collected, some of which reflects individual...

Evolutionary biology has tended to focus on adaptive evolution by positive selection as the primum mobile of evolutionary trajectories in species while underestimating the importance of nonadaptive evolutionary processes. In this review, I describe evidence that suggests that primate and human evolution has been strongly influenced by nonadaptive processes, particularly random genetic drift and...

This study examined the interactive effects of task structure, decision rule, and social motive on small-group negotiation processes and outcomes. Three-person groups negotiated either within an asymmetrical task structure (in which a majority of group members have compatible interests) or within a symmetrical task structure (in which no such majority exists). Groups negotiated either under una...

OBJECTIVES This article describes interaction of the Earth's mass-electrolytic conductor on the electrical environment of human organism-aqueous environment and skeleton. In this environment, bioelectrical and bioenergetical processes take place. METHODS AND SUBJECTS Measurements of electric potential on tongue, teeth, nails, and in venous blood in subjects earthed and unearthed were conducte...

Citizen science projects rely on contributions from volunteers to achieve their scientific goals and so face a dilemma: providing volunteers with explicit training might increase the quality of contributions, but at the cost of losing the work done by newcomers during the training period, which for many is the only work they will contribute to the project. Based on research in cognitive science...
