精神分裂症患者的疾病表达与身份困境——一项基于知乎的实证研究

基于知乎的25起自述文本,研究精神分裂症患者的疾病表达,探究患者病程对叙事类型产生的影响,剖析患者面临的身份困境。研究发现,接受治疗的患者偏向于康复叙事,未治疗的患者偏向于混乱叙事和探寻叙事;同时,精神分裂症患者面临本我、自我与超我相互冲突的身份困境。未来可以在传播层面针对性加强精神疾病类的科普教育以促进患者就医;在叙事层面挖掘以病患作为主体传播模式的潜力、深化叙事疗法中的共情体验以辅助患者建构身份。

     

Odors Can Serve as Landmarks in Human Wayfinding

Scientists have shown that many non‐human animals such as ants, dogs, or rats are very good at using smells to find their way through their environments. But are humans also capable of navigating through their environment based on olfactory cues? There is not much research on this topic, a gap that the present research seeks to bridge. We here provide one of the first empirical studies investigating the possibility of using olfactory cues as landmarks in human wayfinding. Forty subjects participated in a piloting study to determine the olfactory material for the main experiment. Then, 24 subjects completed a wayfinding experiment with 12 odors as orientation cues. Our results are astonishing: Participants were rather good at what we call “odor‐based wayfinding.” This indicates that the ability of humans to use olfactory cues for navigation is often underestimated. We discuss two different cognitive explanations and rule out the idea that our results are just an instance of sequential learning. Rather, we argue that humans can enrich their cognitive map of the environment with olfactory landmarks and may use them for wayfinding.     

Psychological effects of urban and rural domiciles

The purpose of the investigation was to examine some problems concerning physical and mental differences between the population born and living in a large urban community (Group A), those who had moved from rural to urban setting (Group B), and stationary rural subjects (Group C). Each group consisted of 100 men between the ages of 19–25 years (total N= 300).     

A Longitudinal Study of Racial Discrimination and Risk for Death Ideation in African American Youth

Although multiple studies have found that African Americans commonly experience racial discrimination, available studies have yet to examine how perceived racism might be related to suicide vulnerability in African American youth. The purpose of this study was to examine a framework for how perceived racial discrimination contributes to symptoms of depression and anxiety as well as subsequent suicide ideation and morbid ideation. Data were obtained from 722 African American youth at mean age 10.56 years (SD = 0.64); a second wave of data was obtained 2 years later. Results revealed both a direct effect and mediated effects of perceived racism on later suicide and morbid ideation. For boys and girls, the effect of perceived racism was mediated by symptoms of depression. However, the association was mediated by anxiety for girls, but not for boys in the current sample. Implications for future research and interventions are discussed.
