ResumenLa amplitud perceptual, definida como la zona alrededor del punto de fijación de la que se extrae información funcional para el procesamiento, es mayor a la derecha que a la izquierda de éste, al menos cuando se procesa material verbal. Esta asimetría en la amplitud perceptual ha sido puesta de manifiesto con diferentes paradigmas experimentales que revisamos en este trabajo. Revisamos igualmente las distintas hipótesis que se han propuesto para su explicación, para concluir con algunas implicaciones que este dato pudiera tener para otros estudios que utilizan presentación de material verbal en parafóvea. 相似文献
Objective: This study examined the interactive role of affectivity and stress in substance use severity among ethnic minority, emerging adult males, using linguistic indicators of affect obtained through social media.
Method: Participants were 119 emerging adult, ethnic minority males (ages 18–25) who provided access to their mobile phone text messaging and Facebook activity for 6-months. Computerized text analysis (LIWC2015) was used to obtain linguistic indices of positive and negative affect from texts and Facebook posts. The Perceived Stress Scale was used to measure stress, and items from the Drug Abuse Screening Test were used to measure substance use severity.
Results: Generalized estimating equations showed that higher negative affect in texts was associated with greater substance use severity. Stress moderated the relationship between positive affect expressed in Facebook posts and substance use such that higher positive affect in Facebook posts was associated with less substance use at higher stress and greater substance use at lower stress.
Conclusions: Findings highlight the complexities of interactions between stress and affectivity. Findings could inform development of substance use interventions for young males that employ social technologies. 相似文献
Although many studies have investigated individual differences in online social networking, few have examined the recent and rapidly popularized social phenomenon of the “selfie” (a selfportrait photograph of oneself). In two studies with a pooled sample of 1296 men and women, we tested the prediction that individuals who score high on four narcissism sub-scales (Self-sufficiency, Vanity, Leadership, and Admiration Demand) will be more likely to post selfies to social media sites than will individuals who exhibit low narcissism. We examined three categories of selfies: own selfies; selfies with a romantic partner; and group selfies, controlling for non-selfie photographs. Women posted more selfies of all types than did men. However, women’s selfie-posting behavior was generally unrelated to their narcissism scores. In contrast, men’s overall narcissism scores positively predicted posting own selfies, selfies with a partner, and group selfies. Moreover, men’s Vanity, Leadership, and Admiration Demand scores each independently predicted the posting of one or more types of selfies. Our findings provide the first evidence that the link between narcissism and selfie-posting behavior is comparatively weak among women than men, and provide novel insight into the social motivations and functions of online social networking. 相似文献
Status updates are one of the most popular features of Facebook, but few studies have examined the traits and motives that influence the topics that people choose to update about. In this study, 555 Facebook users completed measures of the Big Five, self-esteem, narcissism, motives for using Facebook, and frequency of updating about a range of topics. Results revealed that extraverts more frequently updated about their social activities and everyday life, which was motivated by their use of Facebook to communicate and connect with others. People high in openness were more likely to update about intellectual topics, consistent with their use of Facebook for sharing information. Participants who were low in self-esteem were more likely to update about romantic partners, whereas those who were high in conscientiousness were more likely to update about their children. Narcissists’ use of Facebook for attention-seeking and validation explained their greater likelihood of updating about their accomplishments and their diet and exercise routine. Furthermore, narcissists’ tendency to update about their accomplishments explained the greater number of likes and comments that they reported receiving to their updates. 相似文献
Research on the association between social anxiety and social media usage remains inconclusive: despite the preference for computer-mediated communication there is currently no clear empirical support for social anxiety being associated with longer duration of social media use. Self-report measures for social anxiety that are adapted for the context of social media could facilitate further research. The current study aimed to develop a Swedish version of the recently developed Social Anxiety Scale for Social Media Users (SAS-SMU), evaluate its psychometric properties, and explore associations between different uses of social media and social anxiety. Three factors were retained for SAS-SMU with excellent internal consistency. SAS-SMU evidenced convergent validity with measures of social anxiety, negative convergent validity with satisfaction with life, and divergent validity with measures of obsessive-compulsive disorder, depression and generalized anxiety disorder. Results indicated that higher levels of social anxiety were associated with passive and active use as well as longer duration of social media use in general, which is at odds with a previous study where passive use remained the only significant predictor for social anxiety. 相似文献
Fact-checking has become an important feature of the modern media landscape. However, it is unclear what the most effective format of fact-checks is. Some have argued that simple retractions that repeat a false claim and tag it as false may backfire because they boost the claim's familiarity. More detailed refutations may provide a more promising approach, but may not be feasible under the severe space constraints associated with social-media communication. In two experiments, we tested whether (1) simple ‘false-tag’ retractions can indeed be ineffective or harmful; and (2) short-format (140-character) refutations are more effective than simple retractions. Regarding (1), simple retractions reduced belief in false claims, and we found no evidence for a familiarity-driven backfire effect. Regarding (2), short-format refutations were found to be more effective than simple retractions after a 1-week delay but not a one-day delay. At both delays, however, they were associated with reduced misinformation-congruent reasoning. 相似文献
ABSTRACT Interreligious dialogues have received attention since they were introduced as a security policy and social pacification measure after the attack on 9/11. This essay examines the development of interreligious dialogue in Germany as well as the influence of media discourses on interreligious dialogue and asks to what extent they affect the motives, goals and modes of communication of both Muslim and non-Muslim participants. This analysis leads to the thesis that the mass media’s frequent security-policy framing of Islam within issues of integration, violence, and threat has developed interreligious dialogue groups as a space of face-to-face coping processes with the imagined religious conflict. Muslims attend it in order to put Islam in a different and positive frame. For the Christian participants this also presents the opportunity to reach a new relevance of religion in the public secular space. 相似文献
