Schizophrenia is a disabling psychiatric disease characterized by symptoms including hallucinations, delusions, social withdrawal, loss of pleasure, and inappropriate affect. Although schizophrenia is marked by dysfunction in dopaminergic and glutamatergic signaling, it is not presently clear how these dysfunctions give rise to symptoms. The aberrant salience hypothesis of schizophrenia argues that abnormal attribution of motivational salience to stimuli is one of the main contributors to both positive and negative symptoms of schizophrenia...

The consequences of estrogen deprivation and therapeutic interventions such as radiation, chemotherapy and surgery have a significant negative impact on libido, sexual arousal, orgasmic function and the ability to have pleasurable intercourse. Evaluation and treatment of female sexual dysfunction is a significant unmet need in the breast cancer survivor in spite of the availability of safe and effective treatments.

Increased cognitive distortions (i.e. biased processing of chance, probability and skill) are a key psychopathological process in disordered gambling. The present study investigated state and trait aspects of cognitive distortions in 22 individuals with Internet Gaming Disorder (IGD) and 22 healthy controls. Participants completed the Gambling Related Cognitions Scale as a trait measure of cognitive distortions, and played a slot machine task delivering wins, near-misses and full-misses. Ratings of pleasure ("liking") and motivation to play ("wanting") were taken following the different outcomes, and gambling persistence was measured after a mandatory phase...

PURPOSE: The aim of this study was to assess post-match perceived exertion, feeling and wellness according to the match outcome (winning, drawing or losing) in professional soccer players. METHODS: Twelve outfield players were followed during 52 official matches where the outcomes (win, draw or lose) were noted. Following each match players completed both a 10-point scale rating of perceived exertion (RPE) and an 11-point scale rating of perceived feeling. Rating of perceived sleep quality, stress, fatigue and muscle soreness were collected separately on a 7-point scale the day following each match...

While individual differences in reward sensitivity are believed to generalize across drugs and alternative rewards, this notion has received little empirical attention in human research. Here, we tested whether individual differences in the subjective rewarding effects of physical activity were associated with the subjective response to d-amphetamine administration. Healthy volunteers ( n=95; age 18-35 years) completed questionnaires measuring the self-reported pleasurable effects of physical activity and other covariates, and this was followed by two double-blind counterbalanced sessions during which they received either 20 mg oral d-amphetamine or placebo...

The moving testimony of a patient shows the impact which a successful encounter can have. Beyond the positive clinical consequences, her rediscovered motivation and pleasure are the essential drivers which have guided her along the pathway of reconstruction. A tale of two encounters which have marked her life course.

The present study describes the development and validation of a facial expression database comprising five different horizontal face angles in dynamic and static presentations. The database includes twelve expression types portrayed by eight Japanese models. This database was inspired by the dimensional and categorical model of emotions: surprise, fear, sadness, anger with open mouth, anger with closed mouth, disgust with open mouth, disgust with closed mouth, excitement, happiness, relaxation, sleepiness, and neutral (static only)...

This study investigated how frequently a group of young heterosexual Australians (ages 15 to 29) saw a range of behaviors represented in pornography over the previous 12 months. Participants were recruited to an anonymous online survey. Those who reported having viewed pornography in the past 12 months (n = 517) indicated how frequently they saw each of a list of 17 behaviors when they watched pornography in the past 12 months. Men's pleasure (83%) was seen frequently by the highest proportion of young people surveyed, followed by a man being portrayed as dominant (70%)...

The μ opioid receptor (MOR) in the nucleus accumbens (NAc) is involved in assigning pleasurable, or hedonic value to rewarding stimuli. Importantly, the hedonic value of a given rewarding stimulus likely depends on an individual's current motivational state. Here, we examined the involvement of MORs in the motivation to interact with a novel or a familiar (cage mate) conspecific in juvenile rats. First, we demonstrated that the selective MOR antagonist CTAP administered into the NAc reduces social novelty preference of juvenile males, by decreasing the interaction time with the novel conspecific and increasing the interaction time with the cage mate...

BACKGROUND: Socioeconomically vulnerable people are likely to have more health risks because of inadequate behaviour choices related to chronic social stresses. Brain science suggests that stress causes cognitively biased automatic decision making, preferring instant stress relief and pleasure (eg, smoking, alcohol use and drug abuse) as opposed to reflectively seeking health-maintenance services (eg, health check-ups). As such, hedonic stimuli that nudge people towards preventive actions could reduce health behaviour disparities...

BACKGROUND: Potocki-Lupski syndrome (PTLS) and Smith-Magenis syndrome (SMS) are related genomic disorders, as duplication 17p11.2 (associated with PTLS) is the reciprocal recombination product of the SMS microdeletion. While SMS has a relatively well-delineated behavioural phenotype, the behavioural profile in PTLS is less well defined, despite purported associations with autism spectrum disorder (ASD) and the suggestion that some behaviours may be diametric to those seen in SMS. METHODS: Caregivers of individuals with PTLS (N = 34; M age = 12...

REVIEW
Daniel Knowland, Byung Kook Lim
Major depressive disorder (MDD) is a common but serious neuropsychiatric affliction that comprises a diverse set of symptoms such as the inability to feel pleasure, lack of motivation, changes in appetite, and cognitive difficulties. Given the patient to patient symptomatic variability in MDD and differing severities of individual symptoms, it is likely that maladaptive changes in distinct brain areas may mediate discrete symptoms in MDD. The advent and recent surge of studies using viral-genetic approaches have allowed for circuit-specific dissection of networks underlying motivational behavior...

Eugen Wassiliwizky
Eerola et al.'s multi-layered model for the pleasure taken in music-elicited sadness is an important step in integrating explanatory accounts from different disciplines. Here, I would like to point out two theoretical inconsistencies that lie at the very root of the paradox and can have a major impact on future studies: first, the conflation of the transformation hypothesis and the co-activation hypothesis of sadness and pleasure, and second, the conflation of sadness that is elicited by musical instruments and that which is elicited by lyrics...

David A Kahn
OBJECTIVE: The manic spectrum is thought to be characterized by a hypersensitive biobehavioral reward system, the behavioral activation system. Evidence for this framework comes from questionnaire-based, self-report data collected in cross-sectional and prospective studies of mania, mania in remission, and proneness to hypomania, and from functional neuroimaging investigations of brain reward circuit activity during incentivized choice protocols. Although heightened reward anticipation is consistently documented, the status of later goal attainment activity, hedonic responses, and satiety reactions is less clear...
