The Caenorhabditis elegans UNC-13 protein and its mammalian homologues are important for normal neurotransmitter release. We have identified a set of transcripts from the unc-13 locus in C. elegans resulting from alternative splicing and apparent alternative promoters. These transcripts encode proteins that are identical in their C-terminal regions but that(More)
This paper examines controversial claims about the merit of "unconscious thought" for making complex decisions. In four experiments, participants were presented with complex decisions and were asked to choose the best option immediately, after a period of conscious deliberation, or after a period of distraction (said to encourage "unconscious thought(More)

Many everyday tasks involve repeated choices in which past outcomes are used to estimate payoffs but in which present payoffs may differ from past ones. Two experiments with 10 decision problems employing the decisions-from-feedback paradigm examined the choice between two risky options, wherein the payoff probabilities for one option could change over a(More)
There are reliable individual differences in the extent to which people consider the long- and short-term consequences of their behaviors. Such differences, assessed by the Consideration of Future Consequences (CFC) Scale (A. Strathman, F. Gleicher, D. S. Boninger, & C. S. Edwards, 1994), are hypothesized to influence the impact of a persuasive(More)
We extend research on the distinction between decisions from experience or description to situations in which people are given perfect information about outcome probabilities and have experience in an environment which matches the described information. Participants read a description of a die with more sides of one color than another (e.g., 4 black and 2(More)
It can be remarkably difficult to determine whether two photographs of unfamiliar faces depict the same person or two different people. This fallibility is well established in the face perception and eyewitness domain, but most of this research has focused on the "average" observer by measuring mean performance across groups of participants. This study(More)
The authors identify and provide an integration of 3 criteria for establishing cue-search hierarchies in inferential judgment. Cues can be ranked by information value according to expected information gain (Bayesian criterion), cue-outcome correlation (correlational criterion), or ecological validity (accuracy criterion). All criteria significantly(More)
A transient rise in intracellular Ca2+ during fertilization is necessary for activation of the quiescent sea urchin egg. Several mechanisms contribute to the rise in Ca2+ including influx across the egg plasma membrane and release from intracellular stores. The egg contains both IP3-sensitive and -insensitive Ca2+ release mechanisms and in this study we(More)
The effects of memory constraints upon information acquisition and decision making were examined in two experiments using binary prediction tasks, where participants observe outcomes for two options before deciding which one to bet upon. Our studies extend previous investigations to the case where participants learn the structure of the task through(More)
