This paper tests the hypothesis of hedonic adaptation by analyzing the role that a history of heart problems has on the ability to deal with future heart conditions. The results show that those who have had a heart condition in the past are less likely to report worse self-assessed health and emotional health due to the onset of a new condition than those who have not previously had exposure to...

This paper presents a comprehensive theoretical and methodological framework clarifying the relationship between non-market environmental valuation techniques, in particular hedonic and life-satisfaction methods. The paper shows how life-satisfaction scores can be used to test correctly the equilibrium condition in location markets required by the hedonic approach and that in the absence of equ...

It has been postulated that a number of central effects of ethanol are mediated through the action of its first metabolite, acetaldehyde. In particular, acetaldehyde might be involved in the anxiolytic and hedonic effects of ethanol and is therefore believed to play an important role in alcohol abuse. In agreement with this assumption, previous studies indicated that acetaldehyde is mainly rein...

We consider a class of coalition formation games called hedonic games, i.e., games in which the utility of a player is completely determined by the coalition that the player belongs to. We first define the class of subset-additive hedonic games and show that they have the same representation power as the class of hedonic games. We then define a restriction of subset-additive hedonic games that ...

Hedonic hotspots are brain sites where particular neurochemical stimulations causally amplify the hedonic impact of sensory rewards, such as "liking" for sweetness. Here, we report the mapping of two hedonic hotspots in cortex, where mu opioid or orexin stimulations enhance the hedonic impact of sucrose taste. One hedonic hotspot was found in anterior orbitofrontal cortex (OFC), and another was...

Learned flavor preferences can be strikingly persistent in the face of behavioral extinction. Harris, Shand, Carroll, and Westbrook (2004) suggested that this persistence may be due to flavor preference conditioning's producing a long-lasting change in the hedonic response to the conditioned stimulus (CS+) flavor. In the present study, the CS+ flavor was presented in simultaneous compound with ...

Changes in the taste of food have been implicated as a potential cause of reduced dietary intake among cancer patients. However, data on intensity and hedonic responses to the four basic tastes in cancer are scanty and contradictory. The present study aimed at evaluating taste intensity and hedonic responses to simple beverages in 47 anorectic patients affected by gastrointestinal cancer and in...

To examine emotion regulation in later life, we contrasted the modified hedonic treadmill theory with developmental theories, using hassles and uplifts to assess emotion regulation in context. The sample was 1,315 men from the VA Normative Aging Study aged 53 to 85 years, who completed 3,894 observations between 1989 and 2004. We computed three scores for both hassles and uplifts: intensity (ra...
