Tales from the Crypt: On the Role of Death in Life

An existential psychodynamic theory is presented based on Ernest Becker's claim that self-esteem and cultural worldviews function to ameliorate the anxiety associated with the uniquely human awareness of vulnerability and mortality. Psychological equanimity is hypothesized to require (1) a shared set of beliefs about reality that imbues the universe with stability, meaning, and permanence; (2) standards by which individuals can judge themselves to be of value; and (3) promises of safety and the transcendence of death to those who meet the standards of value. An empirical research program in support of this theory is then described, and the personal and interpersonal implications of these ideas are briefly considered.     

Persistence and pleasure in VR: Enhancing Exercise Endurance and Enjoyment through Virtual Environments

Virtual Reality (VR) provides an enjoyable addition to stationary physical exercise and can improve performance while exercising. The aim of this study is to explore the effectiveness of three interactive virtual environments (i.e., social, relaxing, stressful) on enjoyment and persistence during strength-based exercises. In a within-subjects experiment, 97 healthy young adults completed four consecutive sets of two strength-based exercises. Participants completed one set as baseline and then each participant completed three more sets in three different interactive environments, experienced through a VR headset. Results showed that both the stressful virtual environment, where participants were hanging suspended over a city, and the social virtual environment where participants were audibly encouraged in a stadium, increased participants’ persistence in both exercises, when compared to the relaxing virtual environment. Specifically, the relaxing sunny beach environment caused poorer performances in a dead hang exercise among men (n = 30), and poorer performances in a core exercise among women (n = 66). Somewhat paradoxically, this relaxing virtual beach environment was considered the most enjoyable environment among both male and female participants. The potential of VR in exercise lies in its ability to provide pleasurable and performance-enhancing immersive environments that may be too expensive or dangerous in reality.     

Family Therapy and Alternative Medicine: Acupuncture as a Case in Point

Collaboration between family therapists and alternative medicine practitioners is recently cultivated ground that may prove to be fertile territory for the application of family therapy skills. Acupuncture and family therapy are two healing practices that differ in cultural tradition, language, and technique, yet they appear to share some underlying assumptions suggestive of a natural alliance in helping people with a variety of biopsychosociospiritual problems. This paper describes the process of interdisciplinary collaboration between an acupuncturist and family therapist via a clinical vignette, identifying different types of referral situations, and suggesting factors of effective collaboration that can synergistically enhance a patient and family's treatment.     

Virtual Reality Exposure Therapy in the Treatment of Fear of Flying

A new and innovative approach to treating fear of flying has been developed using Virtual Reality Exposure Therapy. This article discusses the development of Virtual Reality Exposure Therapy and reviews a case study of a fear of flying patient seen in our practice. Early results are very promising and may indicate that Virtual Reality Exposure Therapy may also lead to creative interventions with other anxiety disorders.     

虚拟现实技术在心理学领域的应用与展望

虚拟现实(VR)技术因其能够提高实验研究的生态效度、条件控制水平、可重复性以及避免实地操作带来的危险,被众多研究者引入心理学领域。VR技术除了被用于改良实验程序外,也广泛应用于注意、记忆和执行能力等神经心理测验评估,在恐惧症、焦虑症、创伤后应激障碍和精神分裂症等精神障碍的临床治疗中亦取得丰硕成果。未来研究可致力于改进VR技术本身存在的问题、扩大样本量并扩展研究方法和范围,为VR应用提供更可靠的信效度证据。     

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.     

Virtually the same? Analysing pedestrian behaviour by means of virtual reality

Thanks to technological advancements, virtual reality has become increasingly flexible and affordable, resulting in a growing number of user studies conducted in virtual environments. Pedestrian simulators, visualizing traffic scenarios from a pedestrians’ perspective, have thereby emerged as a powerful tool in traffic safety research. However, while both the interest in this technology and the concern for vulnerable road users is high, a systematic overview of research employing pedestrian simulators has not been provided so far.The present literature survey is based on 87 studies published during the past decade, investigating pedestrian behaviour by means of virtual traffic scenarios. Results were categorized according to the research question, technical setup, experimental task, and participant sample. Identifying trends and gaps in knowledge and highlighting differences between methodological approaches, this work serves as an assessment of the current state and a baseline from which to develop future research questions. It aims to demonstrate both opportunities and challenges of this relatively new methodology. Thereby, it is hoped to foster the awareness of existing limitations, support the reasonable interpretation of the available data, and guide pedestrian research towards reliable and generalizable insights enhancing pedestrian mobility, comfort, and safety.     

On the definition of differential reinforcement of alternative behavior

Differential reinforcement of alternative behavior (DRA) has a long history as a behavioral treatment. The term has usually been defined in a manner that suggests one form of behavior (usually some appropriate alternative) is reinforced, while another form of behavior (usually problem behavior) is placed on extinction. In this paper, we will suggest that DRA should not require extinction, either procedurally or by definition. Ideally, problem behavior would be placed on extinction when possible; however, when problem behavior is not or cannot be placed on extinction, the procedure used is still DRA. Thus, we propose the following definition: Providing greater reinforcement, along at least one dimension, contingent on the occurrence of one form or type of behavior, while minimizing reinforcement for another form or type of behavior.     

On the construction of reality and truth. Towards an epistemology of community social psychology

An expression of community social psychology based on the need to transform social reality, and to consider people as the constructors of that reality, is examined from an epistemological point of view. Dualism, the position considering that object and subject are separate entities, and monism, the perspective stating that there is only one substance, are discussed. The consequences of both conceptions for community social psychology, and their incompatibility, as well as the notions of reality and truth are analyzed. That analysis deals with the problems of defining reality, of separating subject and object of knowledge, of language's role, and of relativism and truth. Finally, a constructionist view of monism based on relatedness, and action, is proposed, stating the mutually influencing union of subject and object in the construction of reality.
