Blocking the process of memory reconsolidation by means of amnestic agents may prove to have therapeutic applications. Here we used a morphine-induced conditioned place preference as an index of drug seeking. After inducing in rats a preference for a distinctive compartment paired with morphine, the memory for drug experience was reactivated by a 20-min test session and saline, the beta-antagon...

Infants' preferences for a novel or familiar nursery rhyme were examined as an index of long-term memory. One-to 2-month-old infants' preference were tested, using a nonnutritive sucking, discrimination-learning procedure, at 1, 2, or 3 days after the last of multiple familiarization sessions. A consistent novelty preference was observed at the 1-day retention interval, no consistent preference...

To date, few studies have explored the neurochemical mechanisms supporting individual differences in food preference in humans. Here we investigate how dorsal striatal dopamine, as measured by the positron emission tomography (PET) tracer [(18)F]fluorometatyrosine (FMT), correlates with food-related decision-making, as well as body mass index (BMI) in 16 healthy-weight to moderately obese indiv...

Measuring consistency of preferences is very important in decision-making. This paper addresses this key issue for interval-valued reciprocal preference relations. Existing studies implement one of two different measures: the “classical” consistency measure, and the “boundary” consistency measure. The classical consistency degree of an interval-valued reciprocal preference relation is determine...

Deeply personalized database applications require intuitive and powerful preference query languages like Preference SQL, employing preference constructors that are closed under strict partial order semantics. However, sophisticated preference query optimization and efficient evaluation techniques are essential for a large-scale and successful practical use. In this paper we focus on the evaluat...
