This study extends earlier work by [Kahneman, D., and Snell, J. (1992). Predicting a changing taste: Do people know what they will like? Journal of Behavioral Decision Making, 5, 187-200.]. suggesting that people are poor at predicting changes in liking. This is an important issue because an absence of this ability would make it difficult for people to optimize their own choices. Twenty undergr...

Mu-opioid systems in the medial shell of the nucleus accumbens contribute to hedonic impact ("liking") for sweetness, food, and drug rewards. But does the entire medial shell generate reward hedonic impact? Or is there a specific localized site for opioid enhancement of hedonic "liking" in the medial shell? And how does enhanced taste hedonic impact relate to opioid-stimulated increases in food...

A specialized cubic-millimeter hotspot in the rostrodorsal quadrant of medial shell in nucleus accumbens (NAc) of rats may mediate opioid enhancement of gustatory hedonic impact or "liking". Here, we selectively stimulated the three major subtypes of opioid receptors via agonist microinjections [mu (DAMGO), delta (DPDPE), or kappa (U50488H)] and constructed anatomical maps for functional locali...

Why do certain group members end up especially liking each other more than others? The prediction of interpersonal attraction has been a longstanding pursuit in the social sciences. We combine functional MRI and longitudinal social network data to test whether newly acquainted group members’ reward-related neural responses to one another predict their future attractions after completing a summe...

Attribution theory predicts that actions seen as specifically directed toward a person have greater impact than those not so directed. It was hypothesized that agreement between self-evaluation and another's evaluation increases personalism of received evaluations, increasing both impact and tendency to reciprocate liking or disliking. In a 2 x 2 x 2 factorial design, 66 subjects received a hig...

Extreme macronutrient intakes possibly lead to different brain signalling. The aim of the present study was to determine the effects of ingesting high-protein v. high-carbohydrate food on liking and wanting task-related brain signalling (TRS) and subsequent macronutrient intake. A total of thirty female subjects (21.6 (SD 2.2) years, BMI 25.0 (SD 3.7) kg/m²) completed four functional MRI scans:...

OBJECTIVE To quantify the potential impact of reductions in positive subjective measures from human abuse liability studies on real-world rates of nonmedical use of prescription drugs and associated healthcare resource utilization and costs. DESIGN Positive subjective endpoints "overall drug liking," in-the-moment "drug liking," and "drug high" Emaxs (peak effects) were recorded from publishe...

• Sensory-specific satiation comprises decreased food liking and wanting. Distraction during eating reduces sensory-specific satiation. Hunger (the absence of fullness) affects wanting but not liking. Liking hunger predict meal enjoyment. Meal enjoyment post-meal fullness satisfaction. is the transient loss reward value a recently eaten versus uneaten foods. In this study, participants (n = 70 ...

STUDY BACKGROUND Reduction of added salt levels in soups is recommended. We evaluated the impact of a 30% reduction of usual added salt in vegetable soups on elderly and children's saltiness and liking evaluation. METHODS Subjects were elderly and recruited from two public nursing homes (29 older adults, 79.7±8.9 years), and preschool children recruited from a public preschool (49 children, 4...

A popular product testing procedure is to obtain sensory intensity and liking ratings from the same consumers. Consumers are instructed to attend to the sensory attribute, such as sweetness, when generating their liking response. We propose a new model of this concurrent ratings task that conjoins a unidimensional Thurstonian model of the ratings on the sensory dimension with a probabilistic ve...
