The objective of the current study was to investigate the role of perceived parental support as a moderator in the association between adolescents’ expectations in romantic relations and their psychological well-being. The sample consisted of 647 adolescents (boys = 285, girls = 362). Their age ranged from 16 to 18 years (M = 17.19 years, SD = .77) and they were regular students in different colleges of Islamabad and Rawalpindi. They completed the Perceived Parental Support Scale, the Well-being Questionnaire-W-BQ12 and the Romantic Relations Scale for Adolescents. The results showed that there were significant gender differences on expectations in romantic relations and psychological well-being with girls scoring higher than boys on expectations in romantic relations while boys scoring higher than girls on psychological well-being. The results also indicated that there was a significant negative association between expectations in romantic relations and psychological well-being. Findings of the moderation analysis showed that perceived parental support moderated the association. Simple slope analysis indicated that there was a significant negative slope for low and medium levels of perceived parental support while the slope was non-significant for high levels of perceived parental support. These results indicated that perceived parental support counters the negative effect of expectations in romantic relations on psychological well-being during adolescence. It is suggested that perceived parental support is important in planning interventions to improve the well-being of adolescents.  相似文献

Interpersonal distance is a core aspect of mother-child interaction. While conventional measures based on human coders do not fully capture the dynamics of this feature, computational methods provide automatic measures which can detect even small changes and more accurate estimates both spatially and temporally. Using RGB-D sensors (Microsoft Kinect V2), the present study describes a setup to automatically examine interpersonal distance during mother-child interactions, termed Mother-Infant Interaction Kinect Analysis (MIIKA). First, the laboratory setting and the data extraction method are described. By using an ad-hoc algorithm for kinematic data extraction, MIIKA returns three metrics: barycenter position (distance and velocity of approach and separation), movements (number of small, medium and large approaches and separations) and contributions (proportional contributions of mother and child to approaches and separations). Secondly, preliminary MIIKA metrics are described for a non-clinical mother-child dyad as an exemplification of the protocol. As interpersonal distance can be affected by contingent situations, we detected mother-infant full skeleton during three interactional contexts characterized by different kinds of dyadic exchanges: a free play session, a task-oriented activity and an emotionally arousing condition. Results highlighted similarities and differences between the three interactional contexts. MIIKA appears to be a promising setup to automatically examine interpersonal distance in early mother-child interactions.  相似文献

In two recent papers, Rose and Nichols present evidence in favor of the view that humans represent category essences in terms of a telos, such as honey-making, and not in terms of scientific essences, such as bee DNA. Here, I challenge their interpretation of the evidence and show that it is directly predicted by the main theory they seek to undermine. I argue that their results can be explained as instances of diagnostic reasoning about scientific essences.  相似文献

The psychological distance of objects (e.g., things, places, other people) affects how we think about them. Research suggests that psychological proximity and distance might be also related to positive and negative evaluations, respectively. In this study, we examined whether we can infer how children aged 13–16 years evaluate objects based on their statements regarding the psychological distance between themselves and these objects. Using a mixed-methods design, we verified the relationship between evaluations of objects and whether they are perceived as psychologically close or distant, in a sample of secondary school students. School subjects were predominantly used as evaluation objects. Students used a worksheet that allowed them to visually demonstrate perceived psychological distance between themselves and objects, and then they were asked to explain their choice. Results suggested a strong association between psychological distance and positive or negative evaluation. Thus, the implications of our findings may be relevant for psychodiagnostics.  相似文献

Carpooling is a sustainable, economical, and environmental friendly solution that can significantly reduce air pollution and traffic congestion in urban areas. In spite of its numerous benefits, commuters are still skeptic about adopting it as a routine choice for transportation. This study attempts to map commuters’ attitude towards carpooling services. The study has focused on a few motivational constructs that can have an influence on commuters’ behavior. The study has looked at the role of cognitive complexity and empowerment perceptions of commuters to check if these constructs significantly intervene in the behavioral outcomes. The methodology used is a scenario-based 2 × 2 survey design where the sample is an individual who has experience with carpooling. The survey has used two levels (high, low) each of cognitive complexity and psychological empowerment to give rise to four scenarios. The final sample consisted of 400 carpoolers selected from an IT park having more than 5000 employees. MANOVA analysis showed that cognitive complexity and psychological empowerment had significant influence on the motivational constructs used in the study. Value beliefs, safety and platform quality perceptions were found to have a direct impact on attitude formation and intention to engage in carpooling behavior. The findings offer many implications for managers in the sense that that they can focus on creating suitable communication that creates favorable perceptions towards carpooling to bring about better adoption intentions.  相似文献

A safe headway to the lead vehicle is important to reduce conflicts with merging vehicles from highway on-ramps. Previous research has outlined the advantage of gap metering strategies to yield sufficient space to merging vehicles and improve highway capacity during peak hours. However, prevailing gap metering systems fail to indicate the minimum required gap and leave it to the drivers’ judgment to adjust their headway. This paper proposes a new Active Gap Metering (AGM) signalization that helps outer lane drivers to adjust their headway to the lead vehicle when approaching highway ramps with incoming vehicles. This AGM signalization represents a combination of pavement markings and an innovative Variable Message Sign (VMS). The AGM system was tested alone and in combination with additional variable speed limits (VSL) in distinct environments of the Doha Expressway in the State of Qatar using a driving simulator. The driving behavior of 64 drivers was analyzed using repeated-measures ANOVA. The results showed that the AGM effectively influenced the drivers’ behavior on the right stream lane. Drivers did gradually increase the distance to the lead vehicle, which resulted in optimal headways to merging on-ramp vehicles. Most importantly, the minimum time-to-collision (TTCmin) to the merging vehicle was increased by an additional 1–1.5 s as compared to no treatment. The proposed AGM signalization can, therefore, be considered by policymakers to influence drivers’ headways at critical merging sections.  相似文献

An athlete's connection to their team and team members is an important part of their sport experience. However, researchers currently know little about the nature of these social dynamics with respect to concussed athletes. Our study explored athletes' recovery and reintegration into the team environment following a sport-related concussion. We conducted semi-structured interviews with each member of three athlete-teammate-coach triads (N = 9). We analysed the data using thematic narrative analysis and present the results as three stories that focused on each athlete's experience. For Cassie, we found two major plot points in her story: the transition in her role (and shift in identity) from athlete to student assistant coach/team manager and, once recovered, back to an athlete on the team. For Jess, we found that the main plot in her story was “pressure”. Specifically, the interplay between internal (placed on herself) and external (perceived from teammates and coaches) pressures to return to sport. In the third and final story, the main plot point was the tensions that arose from Jaden's preferences for social support and the type of support that his teammates and coaches believed he needed during his recovery. Our results highlight the interplay between athlete's personal and social identities, feelings of pressure to return and readiness, and the challenges of providing the right amount and type of social support. This research contributes to our limited understanding of the social dynamics involved in athletes' return to sport following a concussion.  相似文献

This study aimed to examine the prevalence of exercise as a coping strategy among Japanese community-dwelling older adults and its impact on their psychological well-being during the COVID-19 pandemic. In October 2019 (baseline [BL]), 720 community-dwelling older adults living in an urban area in Japan participated in a comprehensive health survey. Of these, 618 responded to a mail survey (follow-up [FL]) in June 2020, after the first state of emergency was lifted. Their psychological well-being was assessed using the WHO-5 Well-Being Index (WHO-5). Exercise as a coping strategy during the stay-at-home period was determined at FL by asking respondents whether they had engaged in 1) walking and 2) at-home exercise and strength training to maintain their physical and mental health. Each type of exercise’s impact and the effective exercise combinations were examined. Time and group interaction effects on the WHO-5 scores were investigated using a two-way analysis of covariance. Of the final sample, 65.1% engaged in walking. The WHO-5 mean scores at BL and FL were 16.7 and 15.4 for the walking group and 16.7 and 14.5 for the non-walking group, respectively; interaction for time and group was significant. Additionally, 56.4% of the participants engaged home training. The WHO-5 mean score at BL and FL were 17.5 and 15.5 for the home training group and 15.7 and 14.5 for the no home training group, respectively; there was no significant interaction. Older adults who engaged in both walking and home training received higher score on the WHO-5 than those who engaged in only one activity at FL. The decline in psychological well-being was most attenuated in the walking only group compared to the at-home exercise and strength training groups. Exercise as a coping strategy during the stay-at-home period was associated with psychological well-being, with different impacts observed depending on the type of activity.  相似文献

Leader distance theory has received scant empirical attention in the extant literature; however, the “work from home” orders associated with COVID-19 have made this theory and its empirical findings highly relevant for organizations. Our study integrates leader distance theory and followership theory to understand how follower role beliefs affect follower effort, performance, and withdrawal under physical leader distance and varying conditions of leader interaction frequency. Using a three-wave survey methodology with 260 adults working remotely, our study finds that followers' levels of effort, performance, and withdrawal were contingent on leader interaction frequency. Specifically, followers with a coproduction role orientation, who see their role as more collaborative, reported higher levels of effort under conditions of high leader interaction. Furthermore, the indirect effect of coproduction on follower performance and withdrawal via effort was moderated by leader interaction frequency. The results for followers with passive role orientations, however, were in the opposite direction. These followers reported less effort when leader interaction was high, and the mediational chain predicting performance and withdrawal was contingent on leader interaction frequency. Our study contributes to the ongoing conversation about the positive and negative effects of leader distance and positions followership characteristics as important boundary conditions of distal leadership.  相似文献
