The somatic and psychosocial development of 80 subjects with manifest affective-phasic psychoses is studied retrospectively and compared with that of an identically sized control group consisting of neuropsychiatrically healthy subjects. Statistically significant differences were found particularly in the answers to questions dealing with social situation and social adaptability. Achievement at school and vocational qualifications were lower among the parents of the patients than among those of the healthy subjects. Characteristic features of the patients' childhood and adolescence were transient depression, often for no apparent cause, and maladaption, and vocational wishes were fulfilled less often than among the controls. The patients experienced greater difficulty in settling in to a new group due to their contact difficulties. 相似文献

By 48 patients with Wilson's disease the brainstem acoustic evoked potentials were stated. There were 35 pathological findings (73%), 13 were normal (27%). The waves, determined by the middle and upper brainstem (Pons and Mesencephalon) showed most of all pathological changes. Those patients with forms of Wilson's disease called Pseudoskelerose and Pseudoparkinson showed the most pathological findings. But one could watch these findings by about 30% of patients in preclinical stage. This method can possibly be used for early detection of disorders of brainstem functions and in the same way it can be used for control of treatment by patients in preclinical stage. 相似文献

As the world has become increasingly concerned about environmental plastic pollution, private and public sectors remain devoted to creating effective green marketing campaigns on social media platforms. Drawing upon construal level theory and appraisal tendency theory, this research examines the interaction effect of green ad appeals and two distinct emotions—awe and guilt—on consumers' social media engagement and pro-environmental intentions. The findings from two experimental studies demonstrate that when individuals experience awe, desirability (vs. feasibility) message appeals generate stronger engagement in social media green campaigns. In contrast, it was found that when individuals experience guilt, feasibility (vs. desirability) message appeals enhance social media engagement and pro-environmental behaviors more effectively. This research offers novel theoretical contributions to the existing body of literature and provides practical insights by suggesting that awe and guilt act as moderators leading to greater consumer responses when used with matching social media messages promoting green campaigns. 相似文献

This research investigated the interplay between mood, disclosure language, and ad skepticism on consumers' recognition and evaluation of native advertising. During two online experiments, participants first received a mood manipulation and then read an article-style native advertisement. Results from both studies indicated that participants were more likely to recognize a native ad with an explicit rather than an implicit disclosure label, and a negative mood was more likely than a positive mood to drive participants to recognize the native ad. More importantly, participants in a positive mood evaluated a native ad with an implicit disclosure more favorably than an ad with an explicit disclosure. By contrast, participants in a negative mood responded more positively to a native ad with explicit disclosure compared to an ad with implicit disclosure. Study 2 demonstrated that the interaction between mood and disclosure language was further moderated by individuals' levels of ad skepticism. These results are believed to provide meaningful theoretical and practical implications to the field of native advertising and consumer behavior. 相似文献

The problem of assessing concrete transitivity of length is explored with a non-verbal design employing nine sets of three sticks each. A training phase is used to establish the relevant variable to which the subjects must attend, to obtain a bead. A test phase consists of eight trials, in which the elements A, B, and C, are displayed in a systematic variation. A subject is said to display transitivity, when he more than five times in the eight trials chooses the largest of three sticks, A, on the basis of the information A > B and B 7< C. In a group of 20 children, varying in age between 52 and 80 months, half of the group, which is socio-economically upper-middle class, displayed transitivity. However, the youngest child displaying transitivity with six correct test-trials was 5 1/2 years old. The youngest child displaying transitivity with eight correct trials was 6 1/4 years old. 相似文献
