Aesthetic chills are a peak emotional response to stimuli such as music, films, or speech characterized by shivers and goosebumps and activation of dopaminergic circuits. Despite growing scientific interest in this phenomenon, repeated exposure to chills stimuli has not been studied yet, due to the absence of a validated database. This study leverages a recent gold standard in chills stimuli to investigate the impact of repeated exposure on the frequency and intensity of aesthetic chills. Participants (n = 58) were randomly exposed to 6 chill-evoking stimuli pre-validated on the population of interest, in a counterbalanced order. Our findings revealed a significant decrease in the likelihood of experiencing chills with repeated exposure, suggesting habituation to chills itself or potential fatigue in response to aesthetic stimuli. However, we observed an increase in the intensity and duration of chills over successive exposures among those who did experience chills. The study also identified distinct demographic and psychophysiological response patterns across different participant groups, indicating variability in chill responses. These results provide insights into the dynamic nature of aesthetic experiences and their underlying neural mechanisms, with implications for understanding emotional and reward processing in psychophysiology.

Visual aesthetic experiences unfold over time, yet most of our understanding of such experiences comes from experiments using static visual stimuli and measuring static responses. Here, we investigated the temporal dynamics of subjective aesthetic experience using temporally extended stimuli (movie clips) in combination with continuous behavioral ratings. Two groups of participants, a rate group (n = 25) and a view group (n = 25), watched 30-second video clips of landscapes and dance performances in test and retest blocks. The rate group reported continuous ratings while watching the videos, with an overall aesthetic judgment at the end of each video, in both test and retest blocks. The view group, however, passively watched the videos in the test block, reporting only an overall aesthetic judgment at the end of each clip. In the retest block, the view group reported both continuous and overall judgments. When comparing the two groups, we found that the task of making continuous ratings did not influence overall ratings or agreement across participants. In addition, the degree of temporal variation in continuous ratings over time differed substantially by observer (from slower \"integrators\" to \"fast responders\"), but less so by video. Reliability of continuous ratings across repeated exposures was in general high, but also showed notable variance across participants. Together, these results show that temporally extended stimuli produce aesthetic experiences that are not the same from person to person, and that continuous behavioral ratings provide a reliable window into the temporal dynamics of such aesthetic experiences while not materially altering the experiences themselves.

Background Aesthetic medicine has evolved significantly, accommodating diverse demographics and motivations influenced by societal shifts and technological advancements. The IMPACT (integrative multigenerational psychological analysis for cosmetic treatment) study refines patient archetypes, integrating psychological theories to tailor treatments, especially for younger demographics and LGBTQIA + communities. Methods This cross-sectional study utilized a comprehensive, validated survey with a Cronbach’s alpha of 0.89 and a Content Validity Index (CVI) of 0.92, distributed across a globally diverse, generationally stratified sample. Techniques like regression analysis, ANOVA, Bayesian modelling, and factor analysis were employed to analyse the data, focusing on developing nuanced patient archetypes. Results Among 5645 participants, 5340 complete responses highlighted significant generational differences in aesthetic preferences. Millennials showed a strong preference for non-invasive procedures ( β = 0.65, p < 0.001). ANOVA results confirmed significant variances across generations [F (3, 5118) = 157.6, p < 0.001], with post-hoc analyses delineating specific inter-group differences. Bayesian modelling provided insights into the probability of non-invasive preferences among younger cohorts at over 92% certainty. Factor analysis revealed key dimensions such as ‘Generational Influence’ and ‘Technological Adoption,’ which helped in defining archetypes including Dynamic Self-Identity, Digital Native, Stability Seeker, Classic Conservatism, and Holistic Health, collectively explaining up to 78% of the variance in responses. Conclusion The IMPACT study underscores the influence of generational identity and digital exposure on aesthetic preferences, advocating for personalized, archetype-based treatment approaches. This aligns with enhancing patient satisfaction and treatment outcomes, promoting an adaptive aesthetic medicine practice that meets the evolving needs of modern patients.

The aims of this study were to evaluate the impact of cosmetic and functional outcomes after breast-conserving surgery (BCS) and radiation on quality of life (QOL). In this exploratory analysis; baseline, 5 and 10 years data of patient’s assessment of breast cosmesis, arm swelling/pain, limitation of movement, loss of feeling in fingers and breast sensitivity/tenderness were dichotomized and their impact on QOL (QLQ-C30) were assessed. Multivariable modelling was also performed to assess associations with QOL. The St. George and Wollongong randomized trial randomized 688 patients into the boost and no boost arms. 609, 580, and 428 patients had baseline, 5 and 10 years cosmetic data available, respectively. Similar numbers had the various functional assessments in the corresponding period. By univariate analysis, cosmesis and a number of functional outcomes were highly associated with QOL. Adjusted multivariate modelling showed that cosmesis remained associated with QOL at 5 and 10 years. Breast sensitivity, arm pain, breast separation, age and any distant cancer event were also associated with QOL on multivariate modelling at 10 years. This study highlights the importance of maintaining favorable cosmetic and functional outcomes following BCS. In addition, the clinically and statistically significant relationship between functional outcomes and QOL shows the importance for clinicians and allied health professionals in identifying, discussing, managing, and limiting these effects in women with breast cancer in order to maintain QOL.

Understanding what leads people to reverse their choices is important in many domains. We introduce a contrast paradigm for studying reversals in choices-here between pairs of abstract paintings-implemented in both within-subject (Experiment 1; N = 320) and between-subject (Experiment 2; N = 384) designs. On each trial, participants chose between a pair of paintings. A critical pair of average-beauty paintings was presented before and after either a reversal or control block. In the reversal block, we made efforts to bias preference away from the chosen average-beauty painting (by pairing it with more-beautiful paintings) and toward the non-chosen average-beauty painting (by pairing it with less-beautiful paintings). Meta-analysis revealed more reversals after reversal blocks than after control blocks, though only when the biasing manipulations succeeded. A second meta-analysis revealed that reversals were generally more likely for participants who later misidentified their initial choice, demonstrating that memory for initial choices influences later choices. Thus, the contrast paradigm has utility both for inducing choice reversals and identifying their causes.

Background Facial attractiveness is a relevant feature in many societies, and self-perceived attraction has been shown to affect a wide range of aspects in human lives, including quality of life. The present study assessed the mediating effects of behavioral determinants on self-reported dental and facial esthetics in an academic population. Methods A cross-sectional observational study on 1,232 students from Universidad Cooperativa de Colombia, Pasto, Colombia was conducted. Socio-demographic variables such as age, sex, residency, place of birth, living zone, socioeconomic status, and type of faculty (Dentistry, Medicine, Nursing, Engineering and Law) were included. Moreover, clinical characteristics related to oral rehabilitations of anterior teeth (composites and crowns) were recorded. Behavioral determinants such as self-esteem, self-compassion, social achievements, and social anxiety were evaluated through Rosenberg’s Self-Esteem Scale (RSE), Self-compassion Scale (SCS), Social Achievement Goal Scale (SAG) and Social Anxiety Questionnaire for Adults (SAQ-A30). The Orofacial Esthetic Scale (OES) was employed to determine self-rated dental and facial esthetics. A paper-and-pencil self-administered survey was utilized. Descriptive statistics (frequencies, means and standard deviations) were calculated to determine the levels of personal factors. Structural Equation Modeling (SEM) was performed with robust unweighted least squares estimation method to assess the mediating effects of the behavioral variables on dental and facial esthetics. Analyses were conducted using SPSS 28.0 and EQS 6.2 statistical package. Statistical significance was set at P  < 0.05. Results The sample comprised 496 (40.3%) males and 736 (59.7%) females. 1,068 (86.7%) participants were 18–25 years old, and 164 (13.3%) > 25 years old. The mean and standard deviations ( SD ) of scales were: RSE = 24.24, SD  ± 1.91; SCS = 3.16, SD  ± 0.54; SAG = 32.55, SD  ± 7.97; SAQ-A30 = 74.61, SD  ± 21.33; and OES = 58.12, SD  ± 13.12. SEM found self-compassion (β = 0.38, P  = 0.03), social goals achievement (β = 0.34, P  = 0.02) and self-esteem (β = 0.25, P  = 0.02) had moderate and direct effects on dental and facial esthetics, while social anxiety (β = -0.19, P  = 0.02) displayed a moderate indirect effect. Conclusions Behavioral factors predicted dental and facial esthetics self-perception in college students. Clinicians and educators should be aware of the identified effects which may, in turn, affect overall quality of life of patients and students.

Purpose Intracoronary bleaching is a minimally invasive, alternative treatment that addresses aesthetic concerns related to non-vital teeth discoloration. However, to the best of our knowledge, no studies have assessed the psychosocial impacts of such procedures on patients' aesthetic perceptions. The aim of this study was to evaluate aesthetic perceptions and the psychosocial impact of patients up to 3 months after their teeth had been bleached with hydrogen peroxide (35%) and carbamide peroxide (37%) using the walking bleach technique. Methods The patients were randomly divided into two groups according to the bleaching agent used: G1 = hydrogen peroxide 35% (n=25) and G2 = carbamide peroxide 37% (n=25). Non-vital bleaching was performed in four sessions. Color was objectively (ΔE) and subjectively (ΔSGU) evaluated. Aesthetic perception and psychosocial factors were evaluated before, 1 week and 1 month after the bleaching using the Oral Health Impact Profile (OHIP) and Psychosocial Impact of Dental Aesthetics Questionnaire (PIDAQ) questionnaires. Results The color change (ΔE) values at 1 month were G1 = 16.80±6.07 and G2= 14.09±4.83. These values remained stable until the third month after treatment (p>0.05). There was a decrease in the values of OHIP-aesthetics and PIDAQ after treatment versus baseline (p<0.05). This status was maintained through the third month after treatment. Conclusions Both agents were highly effective and had a positive impact on the aesthetic perception and psychosocial impact of patients, values that also remained stable over time. Non-vital bleaching yields positive and stable impacts on aesthetic perception and psychosocial factors. ClinicalTrials.gov identifier NCT02718183.

The significance of music-induced thrills or chills was explored in 3 experiments (N = 223). Specifically, the ability of antecedent (priming) stimuli in different modalities and aesthetic domains (national anthems, stories, architectural objects, paintings) to increase the participants’ thrills responsiveness to music by Rachmaninoff and Haydn was examined. In addition, the differential effects of having or not having experienced thrills on the participants’ subsequent willingness to donate blood, and on their mood and self-concept, were tested. It was found that while the antecedent stimuli in different modalities could themselves induce thrills in a predictable manner, these priming stimuli, and the thrills they elicited, had relatively weak effects on the thrills subsequently induced by the Rachmaninoff and Haydn pieces. The measures of altruism, self-concept, and mood were not affected by either the antecedent variables or the thrills experience. Thrills may often accompany profound aesthetic experiences and provide their physiological underpinning, yet themselves be of limited psychological significance.

Aesthetic perception and judgement are not merely cognitive processes, but also involve feelings. Therefore, the empirical study of these experiences requires conceptualization and measurement of aesthetic emotions. Despite the long-standing interest in such emotions, we still lack an assessment tool to capture the broad range of emotions that occur in response to the perceived aesthetic appeal of stimuli. Elicitors of aesthetic emotions are not limited to the arts in the strict sense, but extend to design, built environments, and nature. In this article, we describe the development of a questionnaire that is applicable across many of these domains: the Aesthetic Emotions Scale (Aesthemos). Drawing on theoretical accounts of aesthetic emotions and an extensive review of extant measures of aesthetic emotions within specific domains such as music, literature, film, painting, advertisements, design, and architecture, we propose a framework for studying aesthetic emotions. The Aesthemos, which is based on this framework, contains 21 subscales with two items each, that are designed to assess the emotional signature of responses to stimuli's perceived aesthetic appeal in a highly differentiated manner. These scales cover prototypical aesthetic emotions (e.g., the feeling of beauty, being moved, fascination, and awe), epistemic emotions (e.g., interest and insight), and emotions indicative of amusement (humor and joy). In addition, the Aesthemos subscales capture both the activating (energy and vitality) and the calming (relaxation) effects of aesthetic experiences, as well as negative emotions that may contribute to aesthetic displeasure (e.g., the feeling of ugliness, boredom, and confusion).
