This study explored Korean children's understanding of social media advergames. In particular, we investigated the effects of ad recognition and skeptical attitudes toward advertising on children's susceptibility to commercial influences. The results of a survey of 556 children, ranging in age from 7 to 11, showed that half of the children could correctly identify the social media advergame as a type of advertising, whereas the other half could not. Comparisons revealed that older students were better at recognizing commercial influences. In terms of children's intention to visit sites featured in advergames, students who were in a lower grade, female, or had high Internet usage were more likely to want to visit the store advertised. After controlling for demographics and media usage, children's ad recognition and skeptical attitudes, as well as the interaction term, were all statistically significant. The results underscore the importance of combining both cognitive and attitudinal advertising literacy.  相似文献

Humans want to go to Mars now. This entails many difficult but solvable challenges. However, human activity on Mars depends on the answers to three fundamental questions: (1) Is there life on Mars, does that life represent at second genesis of life? (2) Can Earth life, and humans in particular, adapt to the Martian gravity of 0.38?g, and will human generations on Mars speciate from humans on Earth? (3) Is there enough carbon, nitrogen, and water on Mars to create a global habitable environment? These answers must be determined on Mars and will decide the scope of human activities.  相似文献

Suppression of undesirable emotions, as well as beliefs about the unacceptability of experiencing and expressing emotions, have both been shown to be related to poorer health-related outcomes in several clinical groups. Potential models through which these variables relate have yet to be tested in those with irritable bowel syndrome (IBS) and are therefore examined in the current article. Online questionnaires were administered to people with IBS (n = 84) to test a mediation model in which beliefs about the unacceptability of emotions are associated with greater emotional suppression, which in turn relates to increased affective distress and consequently poorer quality of life. An alternate model to test the direction of effect along with two further models using support-seeking as mediators of the same predictor and outcome were also tested. Emotional suppression and affective distress (in that particular order) mediate the relationship between beliefs about emotions and quality of life IBS. The models using support-seeking as mediators of the relationship between beliefs about emotions and the two outcomes were not supported. These findings suggest a role for emotional processing in medically unexplained symptoms and imply the need to address such beliefs about emotions in psychological therapies.  相似文献

Numerous studies have demonstrated that coercive control is more strongly associated with suicidal ideation than other forms of intimate partner violence. However, a majority of these studies focused on samples of help-seeking women. This study examined whether coercive control remains the form of intimate partner violence most strongly associated with suicidal ideation within a sample of nonclinical dating couples. This cross-sectional, survey study on 104 dating couples examined the associations of coercive control (i.e., dominance/intimidation and restrictive engulfment) with suicidal ideation, while controlling for other forms of emotional abuse (i.e., hostile withdrawal and denigration), physical assault, and depressive symptoms. As expected, dominance/intimidation and depressive symptoms, but not denigration and physical assault, were associated with suicidal ideation. Contrary to our hypothesis, hostile withdrawal, but not restrictive engulfment, was associated with suicidal ideation. This study suggests that dominance/intimidation and hostile withdrawal are forms of emotional abuse that are pertinent to suicidal ideation in nonclinical dating couples.  相似文献

Despite well‐documented attention deficits in children with intellectual and developmental disabilities (IDD), distinctions across types of attention problems and their association with academic attainment has not been fully explored. This study examines visual attention capacities and inattentive/hyperactive behaviours in 77 children aged 4 to 11 years with IDD and elevated behavioural attention difficulties. Children with autism spectrum disorder (ASD;= 23), Down syndrome (DS;= 22), and non‐specific intellectual disability (NSID;= 32) completed computerized visual search and vigilance paradigms. In addition, parents and teachers completed rating scales of inattention and hyperactivity. Concurrent associations between attention abilities and early literacy and numeracy skills were also examined. Children completed measures of receptive vocabulary, phonological abilities and cardinality skills. As expected, the results indicated that all groups had relatively comparable levels of inattentive/hyperactive behaviours as rated by parents and teachers. However, the extent of visual attention deficits varied as a result of group; namely children with DS had poorer visual search and vigilance abilities than children with ASD and NSID. Further, significant associations between visual attention difficulties and poorer literacy and numeracy skills were observed, regardless of group. Collectively the findings demonstrate that in children with IDD who present with homogenous behavioural attention difficulties, at the cognitive level, subtle profiles of attentional problems can be delineated.  相似文献

The current study examined how implicit and explicit self-esteem and time spent drinking with friends influence college student drinking after a friendship threat manipulation. Poisson regression analyses revealed that students with low implicit self-esteem showed a greater increase in alcohol consumption when drinking with friends after experiencing a friendship threat than in the control condition. These effects were not found among students with high implicit self-esteem. A similar, but weaker, pattern emerged when testing the independent effects of explicit self-esteem. We suggest that low self-esteem students are drinking because they lack the self-resources to deal with unmet belongingness needs. These findings suggest that low implicit self-esteem may be a risk factor for college student drinking.  相似文献

It was long thought that a key characteristic of object substitution masking (OSM) was the requirement for spatial attention to be dispersed for the mask to impact visual sensitivity. However, recent studies have provided evidence questioning whether spatial attention interacts with OSM magnitude, suggesting that the previous reports reflect the impact of performance being at ceiling for the low attention load conditions. Another technique that has been employed to modulate attention in OSM paradigms involves presenting the target stimulus foveally, but with another demanding task shown immediately prior, and thus taxing executive/temporal attention. Under such conditions, when the two tasks occur in close temporal proximity relatively to greater temporal separation, masking is increased. However this effect could also be influenced by performance being at ceiling in some conditions. Here, we manipulated executive attention for a foveated target using a dual-task paradigm. Critically, ceiling performance was avoided by thresholding the target stimulus prior to it being presented under OSM conditions. We found no evidence for an interaction between executive attention load and masking. Collectively, along with the previous findings, our results provide compelling evidence that OSM as a phenomenon occurs independently of attention.  相似文献
