Flying dreams stimulated by an immersive virtual reality task

Despite a high prevalence and broad interest in flying dreams, these exceptional experiences remain infrequent. Our study aimed to (1) induce flying dreams using a custom-built virtual reality (VR) flying task, (2) examine their phenomenological correlates and (3) investigate their relations to participant state and trait factors. 137 participants underwent VR-flying followed by a morning nap. They also completed home dream journals for 5 days before and 10 days after the VR exposure. VR-flying successfully increased the reporting of flying dreams during the laboratory nap and on the following morning compared to both baseline frequencies and a control cohort. Flying dreams were also changed qualitatively, exhibiting higher levels of Lucid-control and emotional intensity, after VR exposure. Factors such as prior dream-flying experiences and level of VR sensory immersion modulated flying dream induction. Findings are consistent with a new vection-based explanation of dream-flying and may facilitate development of dream flight-induction technologies.     

飞行中惊吓和惊奇的管理——拓展的Landman模型

在飞行活动中,飞行员的惊吓和惊奇反应是导致飞行失控的重要因素。惊吓和惊奇反应可能使飞行员熟练训练过的操作程序和技能被遗忘,取而代之的是不适当的直觉性的行为或草率的决策。现有的使用飞行模拟器的研究表明,Landman模型对减轻飞行员惊吓和惊奇的训练有重要价值。在Landman模型的基础上,我们加入了飞行员心理能力的个体间差别（即拓展的Landman模型）,因此拓展的Landman模型对于飞行员的选拔和训练将具有重要意义。     

Floating with Kim Scott's Benang: Vertigo,settler-colonial mobilities and levitation's geographies

In this paper I explore the strange figure of the levitator within Kim Scott's (1999) Miles Franklin Prize winning novel Benang: From the Heart. Through different genres of art and creative practice, mysticism, religion, science-fiction, magic, and even civil disobedience, the levitator is a poorly acknowledged mobile subject who seems to refuse scholarly enquiry. Levitation is more readily understood as a maligned form of fraud, fakery and social frippery, a figure of esoteric interest. Building on recent attempts to resurrect and reconsider levitators (Adey, 2017; Young, 2018), as well as floating, lighter-than-air atmospheres and elements (McCormack, 2018; Engelmann, 2015), this paper argues that floatations like levitation provide a crucial addition to critical and radical thinking in mobilities, affective life and studies of settler-colonialism. Through Benang, Kim Scott's vast historical and yet intimate novel, the paper works with the floating encounters woven through the politics and ecologies of Western Australia and its racist policies which sought to regulate the Noongar people, an Aboriginal people recognised as the traditional owners of south west Western Australia. Within Benang, levitation, lightness and detachment, become expressions of vertiginous (post)colonial distance, fear, anxiety and escape.     

Anxiety between personality and cognition: The gray zone

The aim of the study was to explore relations between Gray’s revised Reinforcement Sensitivity Theory (rRST) systems (Behavior Inhibition, Behavior Activation and Fight/Flight/Freeze System – BIS, BAS and FFFS) and two cognitive vulnerabilities to anxiety disorders (Intolerance of Uncertainty – IU and Anxiety Sensitivity – AS). The sample comprised 223 participants. The results suggested that BIS was a significant predictor of all components of the anxiety vulnerability measures. However, Freeze and Flight had also significant contributions, particularly in explaining vulnerabilities to physical and social threats as well as inhibitory behaviours while facing uncertainty. The findings provide insights into the nature of AS and IU which is in accordance with the rRST.     

飞行员风险知觉：概念、测量及研究理论取向

风险知觉是飞行员进行正确风险管理的核心,对保证航空安全具有重要作用。本文首先对不同研究者对飞行员风险知觉的概念进行综述,又与传统的知觉和危险知觉进行了区分。其次,文章简明地介绍了飞行员风险知觉的测量方法,包括外显的主观评价法、飞行模拟器测验、内隐联想测验等方法,分析各种方法的内容与其优缺点。最后,本文分别从认知理论取向和组织文化理论取向两个方面来探讨飞行员风险知觉的研究,并针对两种理论取向,提出相应的未来研究方向。     

Jackson-5 scales of revised Reinforcement Sensitivity Theory (r-RST) and their application to dysfunctional real world outcomes

Revised Reinforcement Sensitivity Theory (r-RST) is a neurobiological theory of personality which has many differences compared to the original version. This highlights the need for measurement scales to reflect the revised theory. Study 1 uses exploratory and confirmatory factor analysis to develop and test new scales (the ‘Jackson-5’) which are shown to be internally reliable, have scale inter-relationships matching theory, and to have desirable construct validity properties. Study 2 compares r-RST with original RST in the prediction of delinquency and psychopathy in students. Results suggest the new scales capture the main properties of r-RST and indicate that r-RST provides a substantially different explanation of the personality basis of dysfunctional behavior compared to original RST.
