The Temporal Experience of Pleasure Scale (TEPS) is a self-report instrument that assesses pleasure experience. Initial scale development and validation in the United States yielded a two-factor solution comprising anticipatory and consummatory pleasure. However, a four-factor model that further parsed anticipatory and consummatory pleasure experience into abstract and contextual components was a better model fit in China. In this study, we tested both models using confirmatory factor analysis in an American and a Chinese sample and examined the configural measurement invariance of both models across culture...

While observing a specific traffic sign in the field, we noticed an apparent distortion of size and shape of the circle that contained the sign. This novel illusion manifests as a distortion of the horizontal compared to the vertical dimension of the sign. The illusion seems to be underlined by similar mechanisms to those in the Delboeuf illusion. The aim of our study was to determine the existence and magnitude of the snow tire illusion. We conducted two experiments using the method of constant stimuli. The first experiment was conducted on the standard sign, while in the second, the stimuli were rotated 90° counterclockwise...

Premenstrual syndrome (PMS) consists of repetitious physical and psychological symptoms. The symptoms occur during the luteal phase of the menstrual period and cease when the menstrual period starts. This study included pre-test and post-test experiments between a control group and a test group. The statistical population involved 40 females, chosen based on multistage cluster sampling. The participants were then divided into four groups to undergo treatment with calcium supplement plus vitamin D together with cognitive behavioral therapy (CBT), and were screened with the Premenstrual Syndrome Screening Test (PSST)...

Micro-expression recognition is influenced by emotional contexts at the behavioral level. It is found that the recognition for micro-expressions is poorer following a negative context compared to the recognition following a neutral context. However, it remains unclear whether the modulation takes place in the early or later stage of the processing of micro-expressions as reflected in event-related potentials (ERPs). Using synthesized micro-expressions in this study, we investigated how emotional context modulates the ERP components that are elicited by micro-expressions...

The present study aimed to examine body image attitude in Chinese college students and related psychological consequences. A silhouette-matching test was administered to 425 college students in mainland China. Self-esteem, negative emotions, subjective well-being, and eating-disorder-related weight-controlling behaviors were also measured. Only 12.9% of the participants were satisfied with their figure and the extent of body image dissatisfaction was comparable for both sexes. The majority of the female participants indicated a preference to be more slender...

The good life is the result of flourishing and resilience, but also of being a morally good person. We found that moral identity was associated with engagement, meaning, the identification and acceptance of others (i.e., cooperativeness), and the sense of being part of something bigger than the self (i.e., self-transcendence).

We studied the effect of time windows of a few seconds on the aesthetic appreciation of poems. Both Chinese and German subjects rated traditional Chinese poetic verses more beautiful in a time window of approximately 3 s, irrespective of understanding the poetic content. This observation suggests a common temporal preference for poetry appreciation across a different language background.

This study examined the factor structure of the Chinese version of the Dysexecutive Questionnaire (DEX) in a large nonclinical sample of college students (n = 1,586). All participants completed the self-report version of the DEX. An exploratory factor analysis was first performed on a sub-sample (randomly split, n = 766) and produced a four-factor model (Volition, Intentionality, Inhibition, and Abstract Problem-Solving), which was similar to previous models reported in Western samples. In addition, a series of confirmatory factor analyses was conducted on the remaining sample (n = 820)...

Animals are exposed to regular daily challenges in their environment as well as to unpredictable stressful events, so-called stressors. Both measures require adequate physiological responses that are controlled by the circadian system and the stress system. The two systems are highly linked with each other. The circadian system prepares the animal for the regular daily challenges by upregulating the stress system before the animal's activity phase every day. In addition, unpredicted environmental challenges upregulate the stress system independently of the circadian system...

We aimed to examine sleep patterns and their association with depression and behavior problems among Chinese adolescents in different grades. A cross-sectional study was conducted in 10 cities of mainland China. A total of 8,998 Chinese adolescents (49.3% males) aged 9-20 years completed a self-administered questionnaire that included questions on sleep patterns, depressive symptoms, behavior problems, and demographic characteristics. The percentage of adolescents who slept less than 7 hr on weekdays increased with grade, while the percentage of adolescents who slept less than 7 hr on weekends remained the same...

To a large extent, the pursuit of science takes place in universities. In this essay, I ask the following questions. Supposing there were no universities, and that all the knowledge mankind has ever collected and generated is somehow accessible, would we invent universities to make this knowledge available to address the problems humanity faces? What should those universities perform, and what role would science play in such universities? To look for answers to those questions, I consider the nature of the problems dealt with by science, the knowledge needed to address those problems, the gap between the two, the need for interdisciplinarity and the need to educate the leaders of the future, and finally, the boundaries of scientific knowledge...

Emotion is presumed as a major reason for smoking, but this hypothesis needs support from data with high ecological validity. Regulatory emotional self-efficacy (RESE) is key for emotion regulation, therefore RESE is likely to moderate the relationship between emotional states and smoking. The present study used the ecological momentary assessment (EMA) to record the levels of pleasure, arousal, and smoking craving in 33 male current smokers' daily lives, and examined the moderating effect of RESE in the prediction relationship between emotion and craving...

The aim of this study was to determine whether urban environments with different prominent sensory inputs have an impact on the way-finding strategies of blind people and to identify these impacts, where applicable. We specifically investigated how blind people use their senses to compensate for the lack of visual information and how the priority of senses changes according to the urban context. The participants of the study consisted of nine congenitally blind individuals and the study took place in two urban settings: a dense urban district, Kemeralti district in İzmir; and an urban park, the İzmir Fair Park...

This study aimed to explore the link between jealousy and relationship satisfaction among dating adults in Indonesia. A survey of 150 adults showed that, while the overall level of jealousy was not significantly correlated with relationship satisfaction, correlations exist between relationship satisfaction and certain aspects of jealousy.

Assessments of circadian phase using melatonin are laborious. Sleep-time indices allow for less laborious phase calculations, but common indices weakly represent melatonin phase. We show how a single sleep-time assessment can represent melatonin phase by over 60%, improving the use of subjective sleep to mirror objective circadian phase.

Most elderly lack a synchronized circadian rhythm and often cannot benefit from light therapy. Non-visual effects of light are mediated through intrinsic photosensitive retinal ganglion cells (ipRGCs). With chromatic pupillometry, the functionality of ipRGCs and their functional circuit in the brain can be tested.

A growing body of literature has linked chronotype and sleep to school performance. Chronotype is under the control of the circadian clock and refers to sleep timing and diurnal preferences. Chronotype changes with age and is latest during adolescence, giving rise to a mismatch between the (late) circadian clock and the (early) school clock. In general, evening (late) chronotypes obtain lower grades. School performance is influenced by many other factors, such as motivation, intelligence, and conscientiousness...
