OBJECTIVE There is increasing evidence that schizophrenia patients have difficulties in the hedonic appraisal of odors. In a prior study, we assessed olfactory hedonic perception birhinally and found that males with schizophrenia failed to attach the appropriate hedonic valence to a pleasant odor, despite correctly perceiving changes in odor intensity. Female patients, in contrast, exhibited no...

Food intake is an essential human activity regulated by homeostatic and hedonic systems in the brain which has mostly been ignored by the cognitive neurosciences. Yet, the study of food intake integrates fundamental cognitive and emotional processes in the human brain, and can in particular provide evidence on the neural correlates of the hedonic experience central to guiding behaviour. Neuroim...

Price of Anarchy measures the welfare loss caused by selfish behavior: it is defined as the ratio of the social welfare in a socially optimal outcome and in a worst Nash equilibrium. A similar measure can be derived for other classes of stable outcomes. In this paper, we argue that Pareto optimality can be seen as a notion of stability, and introduce the concept of Price of Pareto Optimality: t...

The objective of this study was to develop a semantically labeled hedonic scale (LHS) that would yield ratio-level data on the magnitude of liking/disliking of sensation equivalent to that produced by magnitude estimation (ME). The LHS was constructed by having 49 subjects who were trained in ME rate the semantic magnitudes of 10 common hedonic descriptors within a broad context of imagined hed...

Intertemporal decisions often involve tradeoffs between certain costs and the timing of consumption or ownership. We argue and empirically demonstrate that, ceteris paribus, consumers are more impatient for hedonic (or luxury) goods than utilitarian (or necessity) goods. However, when making actual purchase decisions involving cost-timing tradeoffs, the effect is reversed and consumers are more...

Hedonic property value models have been frequently used to value environmental amenities (or dis-amenities) since markets for these goods (bads) do not usually exist. Typically, researchers cite Rosen’s (1974) seminal work that allows one to interpret functions of the hedonic regression coefficients as the marginal willingness to pay (MWTP) for the environmental good. A key assumption needed fo...

Increasingly, researchers have acknowledged that consumption activities involve hedonic components. Hedonic consumption relates to affective consumer behaviors in that it deals with the emotive and multisensory aspects of the consumption experience. Because the online shopping environment is characterized by the existence of an IT-enabled web interface that acts as the focal point of contact be...

The hedonic impact of taste is reflected in affective facial reactions made by human infants, other primates, and even rats. Originally studied in human infants, affective reactions to taste have also been used by affective neuroscience to identify hedonic brain systems in studies of animals (via application of neural stimulation, pharmacological activation, and neural lesion manipulations). Th...

Benzodiazepines have been reported to induce eating when administered into the brainstem of rats (either the fourth ventricle or the parabrachial nucleus). Benzodiazepines in the brainstem also have been reported to enhance the hedonic impact of taste, as measured by hedonic/aversive taste reactivity patterns, when administered to the fourth ventricle. The present study examined whether the par...

Intrauterine growth restriction is associated with increased risk for adult metabolic syndrome and cardiovascular disease, which seems to be related to altered food preferences in these individuals later in life. In this study, we sought to understand whether intrauterine growth leads to fetal programming of the hedonic responses to sweet. Sixteen 1-day-old preterm infants received 24% sucrose ...
