There is a growing consensus that the brain computes value and saliency-like signals at the time of decision-making. Value signals are essential for making choices. Saliency signals are related to motivation, attention, and arousal. Unfortunately, an unequivocal characterization of the areas involved in these 2 distinct sets of processes is made difficult(More)
We show how being "jilted"-that is, being thwarted from obtaining a desired outcome-can concurrently increase desire to obtain the outcome, but reduce its actual attractiveness. Thus, people can come to both want something more and like it less. Two experiments illustrate such disjunctions following jilting experiences. In Experiment 1, participants who(More)
Measurements of hippocampal formation atrophy using MRI have been useful in distinguishing demented patients with a diagnosis of probable Alzheimer's disease from cognitively normal controls. To determine whether there is a similar relationship between hippocampal size and dementia in elderly patients suspected of normal pressure hydrocephalus (NPH), the(More)
The hippocampus is a major center for the regulation of the hypothalamic-pituitary-adrenal axis. There is experimental evidence that chronic exposure to high levels of glucocorticoids may be toxic to the hippocampus. We observed elevated mean basal and 60-min cortisol (F) levels in response to adrenocorticotropin stimulation (0.25 mg cortrosyn, i.v. bolus(More)
Under pressure, people often prefer what is familiar, which can seem safer than the unfamiliar. We show that such favoring of familiarity can lead to choices precisely contrary to the source of felt pressure, thus exacerbating, rather than mitigating, its negative consequences. In Experiment 1, time pressure increased participants' frequency of choosing to(More)
Consumers’ experienced utility is often shaped not only by intrinsic aspects of consumption experiences themselves, but also by extrinsic pre-consumption information about those experiences. For instance, consider critics’ ratings of a film, the price or country-of-origin of a bottle of wine, the brand-name of a cola, whether a meal is made from organic(More)
