Adults' emotional reactions to the pain and pleasure of others are influenced by the moral character of those individuals. However, it remains unclear whether children's emotional responses also show such selectivity. To investigate this, we compared 4- to 8-year-old children's emotional responses to the physical pain and pleasure of prosocial versus antisocial puppets. In Study 1, children reported unhappiness after witnessing the pain of the prosocial and antisocial puppets but reported less unhappiness after witnessing the pain of the antisocial puppet. In Study 2, children reported happiness after witnessing the pleasure of both puppets but reported being less happy for the antisocial puppet. These results suggest that children are less likely to empathize with antisocial individuals. Meanwhile, children did not display Schadenfreude (pleasure at others' pain) or Gluckschmerz (displeasure at others' pleasure) toward antisocial individuals in our studies. Moreover, the selectivity of children's emotional responses disappeared after we manipulated the physical competence rather than the moral character of the puppets in Study 3. Our findings help to reveal the moral selectivity of emotional responses to others' pleasure and pain during early childhood.

Creativity has previously been linked with various attentional phenomena, including unfocused or broad attention. Although this has typically been interpreted through an executive functioning framework, such phenomena may also arise from atypical incentive salience processing. Across two studies, we examine this hypothesis both neurally and psychologically. First we examine the relationship between figural creativity and event-related potentials during an audio-visual oddball task, finding that rater creativity of drawings is associated with a diminished P300 response at midline electrodes, while abstractness and elaborateness of the drawings is associated with an altered distribution of the P300 over posterior electrodes. These findings support the notion that creativity may involve an atypical attribution of salience to prominent information. We further explore the incentive salience hypothesis by examining relationships between creativity and a psychological indicator of incentive salience captured by participants' ratings of enjoyment (liking) and their motivation to pursue (wanting) diverse real world rewards, as well as their positive spontaneous thoughts about those rewards. Here we find enhanced motivation to pursue activities as well as a reduced relationship between the overall tendency to enjoy rewards and the tendency to pursue them. Collectively, these findings indicate that creativity may be associated with atypical allocation of attentional and motivational resources to novel and rewarding information, potentially allowing more types of information access to attentional resources and motivating more diverse behaviors. We discuss the possibility that salience attribution in creatives may be less dependent on task-relevance or hedonic pleasure, and suggest that atypical salience attribution may represent a trait-like feature of creativity.

Drug addiction therapies commonly fail because continued drug use promotes the release of excessive and pleasurable dopamine levels. Because the connection between pleasure and drug use becomes hard-wired in the nucleus accumbens (NAc), which interfaces motivation, effective therapies need to modulate this mesolimbic reward system. Here, we report that mice with knockdown of the cation channel TRPA1 (transient receptor potential ankyrin 1) were resistant to the drug-seeking behavior and reward effects of cocaine compared to their wildtype litter mates. In our study, we demonstrate that TRPA1 inhibition in the NAc reduces cocaine activity and dopamine release, and conversely, that TRPA1 is critical for cocaine-induced synaptic strength in dopamine receptor 1-expressing medium spiny neurons. Taken together, our data support that cocaine-induced reward-related behavior and synaptic release of dopamine in the NAc are controlled by TRPA1 and suggest that TRPA1 has therapeutic potential as a target for drug misuse therapies.

Social touch through infant holding, skin-to-skin contact, and infant carrying (babywearing) decreases infant distress and promotes secure attachment. Unknown is the extent to which these effects are the result of the activation of C-Tactile afferents (CTs), the constellation of nerve fibers associated with affective touch, primarily located in the head and trunk of the body. The purpose of the present study was to compare dynamic touch (CTs activated) to static touch (CTs less activated) during a babywearing procedure among infants experiencing Neonatal Opioid Withdrawal Syndrome (NOWS). NOWS is a spectrum of clinical symptoms, including elevated heart rate (HR), associated with withdrawal from intrauterine opioid exposure. We hypothesized that stroking an infant's head during babywearing would amplify the pleasurable effect of babywearing as measured by changes in infant HR. Twenty-nine infants in a Neonatal Intensive Care Unit (NICU) in the Southwestern USA were worn in an infant carrier starting at five days old (M = 5.4, SD = 2.6; 46.2 % White, 26.9 % Latinx, 11.5 % Native American) and physiological readings were conducted daily; heart rates of infants and caregivers were taken every 15-seconds for 5-minutes, before, during, and after babywearing (30 min per phase). Each day infants alternated (randomly) in a static touch (hands-free babywearing) or dynamic touch condition (stroking the top of the infants' head at a velocity of 3 cm/s while babywearing). On average, infants completed 3 dynamic and 3 static babywearing sessions. Hospital and research staff participated in babywearing when a parent was not available (31.0 % of infants were exclusively worn by volunteers, 27.6 % were exclusively worn by parents). We analyzed the data using Hierarchical Linear Models due to the 3-level nested design (N = 29 infants, N = 191 readings, N = 11,974 heart rates). Compared to baseline (infant calm/asleep and without contact), infant's HRs significantly declined during and after babywearing, controlling for pharmacological treatment. These effects were significantly stronger during the dynamic touch condition (reduction in HR of 11.17 bpm) compared to the static touch condition (reduction in HR of 3.74 bpm). These effects did not significantly vary by wearer (mother, father, volunteer). However, differences between the dynamic and static conditions were significantly stronger in earlier babywearing sessions, potentially indicating a learning effect. There was evidence for a calming effect among caregivers as well, particularly in the dynamic touch condition, when caregivers were engaged in active touch. Activation of CTs appears to be an important mechanism in the physiological benefits of babywearing and in the symbiotic role of caregiver-infant attachment.

INTRODUCTION
Involvement in sexual activities increases during adolescence in many countries, including Cambodia. The objective of this study is to explore the perspectives and interpretations of sex held by Cambodian adolescents within the context of their social norms and culture.
METHODS
A qualitative research design was used to conduct in-depth interviews with a purposive sample of 91 Cambodian adolescents aged between 15 and 19 years. Participants were recruited from rural areas, and data was collected through face-to-face interviews using semi-structured interview guides. Thematic analysis was used to analyze the data.
RESULTS
Four themes as perspectives of sex were identified: (1) Desire: Releasing sexual desire and stress; (2) relationship: an emotional connection and demonstration of love; (3) roles: responsibilities within a woman's marital duties; and (4) values: the value of virginity and future engagement. Cambodian adolescents' perspectives and interpretations of sex were deeply influenced by their social norms and cultural values. Men typically perceived sex through the lens of instinct and pleasure, while women often emphasized a deep sense of familial duty and held premarital sex to be morally unacceptable.
DISCUSSION
The findings suggest that interventions aimed at improving the sexual health of Cambodian adolescents should be designed with an understanding of the social norms and cultural values that shape their perspectives and interpretations of sex. Such interventions should focus on promoting safe sex practices and providing accurate and comprehensive sexual education.

BACKGROUND
Depression is a symptom characterized by sadness, loss of interest or pleasure, feelings of guilt or low self-worth, disturbed sleep or appetite, feelings of tiredness and poor concentration. One of the most common mental illnesses in the world and a major contributor to morbidity and mortality is depression. The purpose of this study was to ascertain the prevalence of depression and the risk factors associated with it in women who had advanced pelvic organ prolapse.
METHODS
A facility-based cross-sectional study was conducted to determine depression among advanced pelvic organ prolapse women at Gondar University Comprehensive Specialized Hospital. All women who have advanced pelvic organ prolapse were consecutively included till it reached a total of 367 participants over four months. A structured questionnaire was used to obtain the sociodemographic characteristics, clinical characteristics and depression status of the participants. Depression measures were obtained by using the Patient Health Questionnaire tool, which is validated in the Ethiopian local language for chronic illnesses including pelvic organ prolapse using a cut point of five and above, which is considered to indicate depression. Women who screened positive were linked to a psychiatric clinic for further evaluation and treatment. Data was entered into a computer using Epi Info version 3.5.3 and then exported to STATA version 14 for analysis. Multivariable logistic regressions were fitted and odds ratios with 95% confidence intervals with a P value less than 0.05 were used to identify statistically significant factors.
RESULTS
The prevalence of depression was found to be 47.1% (95% CI: 43-52%). Being rural (AOR = 4.8; CI: 1.11-16.32), having a history of divorce because of pelvic organ prolapse (AOR = 5.5; CI: 1.85-16.32) and having a history of urinary symptoms (AOR = 3.1; CI: 1.12-8.59) were found to be independently associated with depression.
CONCLUSIONS
The prevalence of depression among women with advanced pelvic organ prolapse in this study is high as compared to other studies. Depression screening strategies should be designed for the early identification and treatment of depression among women with advanced pelvic organ prolapse.

As the need for food authenticity verification increases, sensory evaluation of food odors has become widely recognized. This study presents a theory based on electroencephalography (EEG) to create an Olfactory Perception Dimensional Space (EEG-OPDS), using feature engineering and ensemble learning to establish material and emotional spaces based on odor perception and pleasure. The study examines the intrinsic connection between these two spaces and explores the mechanisms of integration and differentiation in constructing the OPDS. This method effectively visualizes various types of food odors while identifying their perceptual intensity and pleasantness. The average classification accuracy for odor recognition in an eight-category experiment is 96.1%. Conversely, the average classification accuracy for sensory pleasantness recognition in a two-category experiment is 98.8%. The theoretical approach proposed in this study, based on olfactory EEG signals to construct an OPDS, captures the subtle perceptual differences and individualized pleasantness responses to food odors.

Live streaming is revolutionizing the landscape of e-commerce, creating new opportunities for platforms and e-tailers to improve their performance. However, little is known about the underlying mechanisms that shape consumer behavior in this burgeoning business phenomenon. This study aims to shed light on the relationships between environmental cues generated by live streaming and online impulse buying. Drawing upon the Stimulus-Organism-Response framework, a comprehensive model was formulated to explore how social cues (streamer interaction, peer interaction) and media cues (vividness, realness) impact pleasure, arousal, perceived uncertainty, and subsequently induce consumers' urge to buy impulsively. The model was tested by survey data from 403 consumers. SPSS and PLS are employed to verify the model. The findings revealed that realness and streamer interaction can reduce perceived uncertainty and foster a pleasant consumer experience, while vividness and peer interaction serve to awaken and delight consumers. Pleasure, arousal, and perceived uncertainty mediate antecedent variables' effects on urge to buy impulsively in a parallel and reverse way, and emotions exert a more powerful influence. This study enriched the research on the influence mechanisms of impulse buying driven by live streaming and provided suggestions for platforms and streamers to optimize product display and guide interaction, which is conducive to leveraging the advantages of live streaming and creating greater commercial value.

Puppy play is a kink activity, in which people dress as, take on the role of, and mimic the physical and emotional behaviours of young canines or pups. We explore how the pup identity, depicted in cellphilms by queer men who are part of the pup community, influences men's body image perceptions using multimodal critical discourse analysis. Participants expressed feelings of dissonance, shame, and self-rejection when viewing themselves as humans, but conveyed excitement, pleasure, and self-celebration when viewing themselves as pups. Participants depicted their body images being transformed by way of puppy gear, puppy spaces, handlers, and playmates, which was said to foster more (self-)acceptance, playfulness, and freedom. This study highlights the potential for puppy play to provide a transformative experience for individuals, allowing participants to explore, re-signify, and embrace their bodies as pups.

The sense of agency varies as a function of arousal in negative emotional contexts. As yet, it is unknown whether the same is true for positive affect, and how inter-individual characteristics might predict these effects. Temporal binding, an implicit measure of the sense of agency, was measured in 59 participants before and after watching either an emotionally neutral film clip or a positive film clip with high or low arousal. Analyses included participants' individual differences in subjective affective ratings, physiological arousal (pupillometry, skin conductance, heart rate), striatal dopamine levels via eye blink rates, and psychopathy. Linear mixed models showed that sexual arousal decreased temporal binding whereas calm pleasure had no facilitation effect on binding. Striatal dopamine levels were positively linked whereas subjective and physiological arousal may be negatively associated with binding towards actions. Psychopathic traits reduced the effect of high arousal on binding towards actions. These results provide evidence that individual differences influence the extent to which the temporal binding is affected by high arousing states with positive valence.
