The Theory of Planned Behaviour (TpB: Ajzen, 1985; 1991) is based on a utility framework, and the Risk-as-Feelings hypothesis (RaF: Loewenstein, Weber, Hsee, & Welch, 2001) is a feelings-based behavioural model. The TpB and RaF are first compared and contrasted. Two empirical studies investigated the predictive power of consequence-based vs. affect-based evaluative judgements for behavioural in...

Human self-reports often indicate that changes in mood are a major contributor to drug relapse. Still, arguments have been made that instances of drug-seeking following abstinence in animal models (i.e. relapse/reinstatement) may be outside of hedonic control. Therefore, the present study utilized ultrasonic vocalizations in the rat in order to evaluate affect during cocaine self-administration...

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...

ackground: Stress, one of the strongest risk factors for depression, has been linked to “anhedonic” behavior and dysfunctional eward-related neural circuitry in preclinical models. ethods: To test if acute stress reduces reward responsiveness (i.e., the ability to modulate behavior as a function of past reward), a ignal-detection task coupled with a differential reinforcement schedule was utili...

Hedonic Estimation under Very General Conditions Using Experimental and Quasi-Experimental Designs This paper develops a generalized hedonic model in which an exogenous shock to a single product attribute can affect other attributes, the markets for the product’s complements and substitutes, and aggregate quantity produced. These factors are shown to be empirically relevant and to cause bias in...

Despite the growth in online reservation in recent years, research surrounding customer continuance intentions regarding this service remains insufficient. This research attempts to fill this gap by integrating the e-service quality model with the expectation–confirmation model (ECM) to measure continuance intentions regarding online reservation. Data was collected from a survey of users who ha...

The quality of an organizational website can be a competitive advantage in an increasingly fierce online environment. This article identifies decisive factors of website quality and assesses their effects on user satisfaction. While past website-quality research focuses on the perspectives of web developers and designers, our study targets web users and integrates perspectives of information sy...

In urban context, urban nodes such as amenity or hazard will certainly affect house price, while classic hedonic analysis will employ distance variables measured from each urban nodes. However, effects from distances to facilities on house prices generally do not represent the true price of the property. Distance variables measured on the same surface are suffering a problem called multicolline...

The pursuit of happiness is a preoccupation for many people. Yet only the pursuit can be promised, not happiness itself. Can science help? We focus on the most tractable ingredient, hedonia or positive affect. A step toward happiness might be gained by improving the pleasures and positive moods in daily life. The neuroscience of pleasure and reward provides relevant insights, and we discuss how...

Pleasure is mediated by well-developed mesocorticolimbic circuitry and serves adaptive functions. In affective disorders, anhedonia (lack of pleasure) or dysphoria (negative affect) can result from breakdowns of that hedonic system. Human neuroimaging studies indicate that surprisingly similar circuitry is activated by quite diverse pleasures, suggesting a common neural currency shared by all. ...
