Impact of Web Page House Listing Cues on Internet Rental

Based on a questionnaire survey combining the stimulus-organism-response (S-O-R) theory with the cues theory, this paper establishes hypotheses and uses partial least squares structural equation modelling (PLS-SEM) to study and analyse the impact of web page house listing cues on Internet rental from the perspective of users. The results indicate that: (1) the relevant cues of Internet renting platforms are effective and worthy of attention, (2) the subjective arousal of the tenants triggers their behavioural changes to a large extent, and (3) the sensitivity of the tenants’ behavioural approaches to their feelings is greater than their purchasing intentions. In the context of the rapid development of the online market, understanding the user's response to target information is essential to promote the optimisation of the Internet rental platform, to improve the efficiency of online housing selection, and to encourage healthy development of the rental housing market.

Narcissism and Subjective Arousal in Response to Sexual Aggression: The Mediating Role of Perceived Power

The present research examined the associations that narcissistic personality features had with subjective arousal in response to sexually aggressive behaviors, as well as whether these associations were mediated by the power that was believed to accompany these behaviors. Participants were 221 community members (115 women, 106 men) who completed a self-report instrument that captured narcissistic admiration (an agentic form of narcissism) and narcissistic rivalry (an antagonistic form of narcissism). In addition, participants were asked to rate how powerful they would expect to feel if they actually engaged in an array of sexually aggressive behaviors (e.g., “Tying up a person during sexual intercourse against her/his will”) as well as how sexually aroused they would be by each behavior. A multilevel mediation analysis revealed that both narcissistic admiration and narcissistic rivalry were positively associated with subjective arousal in response to sexual aggression and that these associations were mediated by the perceived power that was believed to accompany these sexually aggressive behaviors. These results suggest that perceptions of power may play an important role in the connections that narcissistic personality features have with subjective arousal in response to sexually aggressive behavior for both men and women. This discussion will focus on the implications of these results for understanding the connections between narcissism and sexual aggression in both men and women.

Physical exercise increases perceived musical pleasure: Modulatory roles of arousal, affect, or dopamine?

Music’s ability to influence exercise performance is well known, but the converse, how exercise influences music listening, remains largely unknown. Exercise can elevate arousal, positive affect, and neurotransmitters including dopamine, which are involved in musical pleasure. Here we examine how exercise influences music enjoyment, and test for a modulatory role of arousal, affect, and dopamine. Before and after exercise (12 min of vigorous running) and a rest control session, participants ( N = 20) listened to music clips and rated their enjoyment and subjective arousal; we also collected ratings of affect and eye-blink rates, an established predictor of dopamine activity. Ratings of musical enjoyment increased significantly after exercise, but not after the rest control condition. While changes in subjective arousal ratings did not differ between exercise and control conditions, change in subjective arousal correlated with change in music enjoyment. After exercise, the change in music enjoyment had a positive but non-significant correlation with change in eye-blink rates ( r = .36). Positive affect increased more after exercise than after the control session, but the change in positive affect did not correlate with change in music enjoyment. In sum, exercise leads to increased musical enjoyment, and this effect was related to changes in arousal.

Embodying Stressful Events: No Difference in Subjective Arousal and Neural Correlates Related to Immersion, Interoception, and Embodied Mentalization

Repetitive thought about oneself, including one’s emotions, can lead to both adaptive and maladaptive effects. Construal level of repetitive self-referential thought might moderate this. During interoception, which engages areas such as the insula, the anterior and/or posterior cingulate cortex (PCC) and the somatosensory cortex, concrete low level construal self-referential thought is applied, which has been shown to lead to more positive emotions after upsetting events. Contrarily, during immersion, related to neural activity in the default mode network (DMN), abstract high level construal self-referential thought is applied, which is linked to depression. The current study investigated whether the integration of concrete and abstract self-referential thought by means of embodied mentalization leads to less subjective arousal, decreased DMN activity and increased somatosensory activity as compared to immersion, and to more DMN activity as compared to interoception. In the fMRI scanner, participants imagined stressful events while adopting immersion, interoception or embodied mentalization. After each imagined stressful event, participants rated their subjective arousal and how difficult it was to apply the mode of self-referential thought. Results showed that participants felt that immersion was easier to apply than embodied mentalization. However, no differences in subjective arousal or neural activity were found between immersion, interoception and embodied mentalization. Possible reasons for this lack of significant differences are discussed.

Effort beats effectiveness in emotion regulation choice: Differences between suppression and distancing in subjective and physiological measures

Emotion regulation (ER) can be implemented by different strategies which differ in their capacity to alter emotional responding. What all strategies have in common is that cognitive control must be exercised in order to implement them. The aim of the present preregistered study was to investigate whether the two ER strategies expressive suppression and distancing require different amounts of cognitive effort and whether effort is associated with personality traits. Effort was assessed subjectively via ratings and objectively via pupillometry and heart period. In two studies, N = 110 and N = 52 healthy adults conducted an ER paradigm. Participants used suppression and distancing during inspection of positive and negative pictures. They also had the choice to reapply either of the strategies at the end of the paradigm. Although distancing was more effective in downregulation of subjective arousal (Study 1: p < .001, ηp² = .20; Study 2: p < .001, ηp² = .207), about two thirds reapplied suppression, because it was perceived as less effortful. Effort was rated significantly lower for suppression compared to distancing (Study 1: p = .042, ηp² = .04; Study 2: p = .002, ηp² = .13). However, differences in effort were not reflected in pupillary data or heart period. Broad and narrow personality traits were neither associated with the preferred strategy, nor with subjective or physiological effort measures. Findings suggest that people tend to use the ER strategy that is perceived as less effortful, even though it might not be the most effective strategy.

Skin Conductance as an Index of Alexithymic Traits in the General Population

Alexithymia concerns a difficulty identifying and communicating one’s own emotions, and a tendency towards externally-oriented thinking. Recent work argues that such alexithymic traits are due to altered arousal response and poor subjective awareness of “objective” arousal responses. Although there are individual differences within the general population in identifying and describing emotions, extant research has focused on highly alexithymic individuals. Here we investigated whether mean arousal and concordance between subjective and objective arousal underpin individual differences in alexithymic traits in a general population sample. Participants rated subjective arousal responses to 60 images from the International Affective Picture System whilst their skin conductance was recorded. The Autism Quotient was employed to control for autistic traits in the general population. Analysis using linear models demonstrated that mean arousal significantly predicted Toronto Alexithymia Scale scores above and beyond autistic traits, but concordance scores did not. This indicates that, whilst objective arousal is a useful predictor in populations that are both above and below the cut-off values for alexithymia, concordance scores between objective and subjective arousal do not predict variation in alexithymic traits in the general population.

Targeted memory reactivation in REM but not SWS selectively reduces arousal responses

A growing body of evidence suggests that sleep can help to decouple the memory of emotional experiences from their associated affective charge. This process is thought to rely on the spontaneous reactivation of emotional memories during sleep, though it is still unclear which sleep stage is optimal for such reactivation. We examined this question by explicitly manipulating memory reactivation in both rapid-eye movement sleep (REM) and slow-wave sleep (SWS) using targeted memory reactivation (TMR) and testing the impact of this manipulation on habituation of subjective arousal responses across a night. Our results show that TMR during REM, but not SWS significantly decreased subjective arousal, and this effect is driven by the more negative stimuli. These results support one aspect of the sleep to forget, sleep to remember (SFSR) hypothesis which proposes that emotional memory reactivation during REM sleep underlies sleep-dependent habituation.
