The Assessment of Spatial Orientation Using Virtual Reality Techniques

Visual-spatial ability has been identified as one of the primary factors of intelligence. Numerous tests, including paper-and-pencil tasks and laboratory experiments, have attempted to provide an accurate measure of this ability. However, the majority of these tests serve only as surrogate measures of visual-spatial ability and may not provide a precise prediction of the individuals' performance in a real environment. We propose a new approach for evaluating spatial ability. In this article, we introduce the use of virtual reality (VR) or virtual environments (VEs) as a new method to measure human spatial orientation. We then discuss the advantages of using VR or VE over traditional measures. We also comment on their limitations and their future direction.     

The effect of the leader-therapist's style on the therapeutic community's large group

Summary The behaviors of 23 leader-therapists, conducting the Community Meetings of various Therapeutic Communities for psychiatric patients were observed and scored. Observations were focused on the behaviors themselves, the values suggested by them, the ways in which the values were transmitted and characteristics of leadership styles. The results show that leadership behaviors, styles and the values they reflect are very much dependent on the ward and its atmosphere. In the way in which the values are transmitted, however, leaders maintained their own personal habits even when working on different wards. The authors conclude that ward-atmosphere and leadership personality are determining the leaders' behavior in therapeutic community ward meetings more than their theoretical orientation and therapy experience.This article was based on a paper presented at the World Congress of Social Psychiatry, Athens, Greece, 7975.Currently, Dr. Mérei is retired.     

Student Nurses' Experiences of The Clinical Psychiatric Learning Environment in an Education Institution

This study investigated lived experiences of student nurses working in a clinical psychiatric learning environment in South Africa. Participants were 29 fourth-year student nurses in the clinical psychiatric learning environment at a nursing education institution (females = 27; males =2). They engaged in focus group discussion on their experiences of the clinical psychiatric learning environment. The data were thematically analyzed using Tesch's method of open coding. The student nurses experienced the environment as growth enhancing on a professional and personal level.     

Observations on the behaviour of patients in a state mental hospital and a general hospital psychiatric unit: A comparative study

The study sought to compare the naturally occurring behaviour of psychiatric patients within a traditional mental hospital ward and a general hospital psychiatric unit. Direct behavioural observations were undertaken to determine the pattern of behaviour exhibited by patients, the amount of time spent in interaction, with whom interaction took place and the content of that interaction. Data were reliably collected by trained observers, using a 10 category behaviour scale. Within each setting 10 psychotic patients, matched for age, sex and diagnosis, were the subjects and 30 min of behaviour was recorded for each subject. Observations revealed that patients in the mental hospital exhibited more disturbed behaviour, and spent less time in interaction, than did those in the general hospital unit. However, the amount of time patients spent interacting with staff was comparable in the two settings, despite marked differences in staffing levels. Analysis of the content of interaction that did occur indicated that the manner in which staff responded to patients' behaviour was not consistent with the application of a behavioural engineering approach to the modification of abnormal behaviour. While staff in both settings were indiscriminate in the way in which they responded to appropriate and inappropriate patient behaviour, a rather more punitive style of interaction was observed in the mental hospital environment. It is concluded that, from a behavioural perspective, neither setting achieved an optimum therapeutic environment.

Repeated exposure of flight phobics to flights in virtual reality

The present study examined the effects of repeated exposure of flight phobics to flights in virtual reality (VR). Flight phobics were randomly assigned either to complete one VR test flight followed by four VR exposure flights (VR group; N=15) in one lengthy session or to complete one VR test flight followed by a lengthy relaxation training session (relaxation group; N=15). All participants completed a second VR test flight at the end of the session. Fear reports and physiological fear reactions (heart rate, skin conductance level) during VR exposures were registered, and fear of flying was assessed psychometrically from 3 weeks before to 3 months after exposure. Exposure to VR flights elicited subjective and physiological fear responses in flight phobics, and these responses attenuated within and across VR flights. Fear reduction associated with repeated VR exposure was greater than fear reduction caused by relaxation training. Fear of flying improved in both treatment groups, but several outcome measures indicated greater effects in the VR treated group than in the relaxation group. These findings indicate that exposure in virtual reality may offer a new and promising approach for the treatment of fear of flying.     

Virtual environment training system for rehabilitation of stroke patients with unilateral neglect: crossing the virtual street.

In this paper, we propose a system for training of stroke patients with unilateral neglect by using technology of virtual reality (VR). The proposed system is designed to compensate for unilateral neglect. This system contains the calibration of unilateral neglect and the training of this disease. The calibration procedure is implemented by aligning the virtual object at a subjective middle line. The training procedure is implemented by completing the missions that are used to keep the virtual avatar safe during crossing the street in a virtual environment. The results of this study show that the proposed system is effective to train unilateral neglect. The left to right ratio scores extracted from this system gradually decrease as the sessions of training are repeated. To validate the VR system parameters, the parameters are analyzed by correlation with those of traditional unilateral neglect assessment methods (such as the line bisection test and the cancellation test).     

L’équipe paramédicale à l’hôpital psychiatrique : Retentissement actuel d’une évolution de deux décennies Analyse d’un entretien de supervision

At the advent of the reform of nursing education in France, this study attempts to give an overview of changes in the work practices of nurses and the employment of nurse’s aides in psychiatric wards of hospitals. Based on the assumption that interaction acts as an interface between the individual on one side and collective systems on the other, the authors approach this issue by analyzing a supervisory meeting of a caregiving team in a psychiatric hospital.     

Cautious behaviors of pedestrians while crossing narrow streets: Exploration of behaviors using virtual reality experiments

This study explores the cautious behaviors of pedestrians in a typical local street environment using virtual reality (VR)-based experiments under various physical safety design scenarios for roadways. The built environment of this study focused on narrow local roads where frequent daily walking occurs within a neighborhood. VR experiments can provide an objective and accurate measurement of pedestrian behaviors, thus improving the understanding of complicated pedestrian behaviors. Based on experimental data from 200 university students, we identified pedestrians’ crossing behavior that is cautionary or risky concerning various physical safety designs of streets. This study found that there are trade-off relationships between various behaviors which should be systematically studied to produce safer street design guidelines. Furthermore, as the contexts and sequences matter in behaviors for intersection crossing, the interpretation of behaviors should carefully consider the context of built environments and sequential decisions made by pedestrians. This sequential understanding of before- and during-crossing behaviors and their connections expands our knowledge of pedestrians’ crossing behaviors.     

Assessing human reorientation ability inside virtual reality environments: the effects of retention interval and landmark characteristics

The purpose of the present study was to assess the navigational behaviour of adult humans following a disorientation procedure that perturbed their egocentric frame of reference. The assessment was carried out in a virtual reality (VR) environment by manipulating the disorientation procedure, the retention interval, the relative positions of target and landmark. The results of experiment I demonstrated that adding a physical rotation to a virtual disorientation procedure did not yield an additional decrease in searching performance. The results of experiment II showed that shortening the delay between study and test phase decreased the errors more markedly for geometric than landmark ones. An orientation specificity effect due to the manipulation of the relative position between target and landmark was discussed across the experiments. In conclusion, VR seemed to be a valuable method for studying human reorientation. Moreover, the virtual experimental setting involved here promoted knowledge of the relationship between working memory and spatial reorientation paradigm.     

Through a glass darkly Some reflections on psychiatric nursing

Abstract

This paper is about ways of understanding some of the behaviour and events that occur in psychiatric wards. It is argued that a psychodynamic understanding of these events would help both staff and patients see some ‘meaning in madness’.     

Virtual reality applications to agoraphobia: a protocol.

Recently, educators and instructional designers have focused on the development and implementation of virtual learning environments that effectively combine theoretical and applied knowledge to teach university students. One of the trusts of the Psychology Virtual Teaching Laboratory in collaboration with the IXTLI observatory is to develop dissemination programs to promote the insertion of virtual reality (VR) technologies applied to rehabilitation in their clinical practice. This paper describes the development of (1) agoraphobia VR learning objects to be use as a teaching support tools in class and (2) a multimedia teaching program that incorporate digital video and VR scenarios address to students in the field of mental health. Promotion among professors and students about the use of this technology will allow us to initiate research in our country as well as to validate contextualized applications for our culture, therefore contributing with new advances in this field.     

A comparative study of six different inpatient groups with respect to their basic assumption functioning

Seventy-five group therapy sessions of six different inpatient team groups in one short-term, one intermediate term, and one long-term psychiatric ward were studied with Group Focal Conflict Analysis and the Group Emotionality Rating System. The majority of the group sessions (41) functioned as fight-flight groups, twenty-four sessions functioned at a "pseudogroup" level, and ten sessions were dependency groups. The differences between the fight-flight groups and the dependency group on the variables aggression and dependency were highly significant statistically. A mixture of fight-flight groups and pseudogroups were found in the short-term ward with emergency obligations. The author discusses the assets and shortcomings of fight-flight and dependency cultures within psychiatric wards.     

The assessment of gender role stress for Chinese

The present study aimed to extend the generality of the construct of gender role stress (GRS) to Chinese samples. Specific objectives included (1) devising Chinese versions of the Masculine Gender Role Stress Scale (MGRS) and Feminine Gender Role Stress Scale (FGRS) developed by Eisler and his colleagues (2) examining the relationship between GRS and gender role orientation, and (3) evaluating the concurrent validity of GRS by correlating it with a measure of health adjustment. Fifty-one male and 58 female Chinese college students in Hong Kong participated in Study 1, which aimed to develop Chinese versions of the two GRS scales. Similar to Americans, Chinese male students scored higher on the MGRS scale, but lower on the FGRS scale than Chinese female students. Students' scores on the two GRS scales were independent from their global ratings of stereotypic masculinity and femininity. A second sample, consisting of 46 male and 73 female Chinese nurses, was recruited for Study 2, which evaluated the association between GRS and health adjustment. As hypothesized, a high level of MGRS or FGRS was positively related to a high level of health and mental health disturbances for both male and female nurses.This study was funded in part by the Asia Scholarship for Research on Women 1992/93 of the United Board for Christian Higher Education. The authors would like to thank Professor Richard M. Eisler for his permission to translate the MGRS and FGRS scales into Chinese, and the Association of Hong Kong Nurses for their assistance in data collection.     

Therapeutic and counter-therapeutic factors in acute ward settings

Summary

Recent reports suggest that many patients view their admission to a psychiatric acute unit as an unrewarding, distressing or undermining experience. Whilst it could become genuinely therapeutic, in the sense that it could be an opportunity for self-reflection, personal exploration or change, it is often endured as a traumatic event in one's life that should best be forgotten.

This paper explores a psychodynamic understanding of this multi-personal environment in which transference phenomena develop and are usually ‘acted out’. The admission process is examined, as well as the importance of understanding the support and attachment to fellow patients, staff-patient tensions, and relationships between staff and management. Issues about violence and fear, locked wards, and reflective interventions on a unit are discussed, focusing on how to maximise therapeutic opportunities. The multi-disciplinary ward-review is also scrutinised in this light.     

Virtual reality and the new psychophysics

Virtual reality (VR) promises methodological rigour with the extra benefit of allowing us to study the context-dependent behaviour of individuals in their natural environment. Pan and Hamilton (2018, Br. J. Psychol.) provide a useful overview of methodological recommendations for using VR. Here, we highlight some other aspects of the use of VR. Our first argument is that VR can be useful by virtue of its differences from the normal perceptual environment. That is, by virtue of its relative non-realism and poverty of its perceptual elements, it can actually offer increased clarity with respect to the features of interest for the researcher. Our second argument is that VR exerts its measurable influence more by eliciting an acceptance of the virtual world (i.e., ‘suspension of disbelief’) rather than by eliciting a true belief of the realism of the VR environment. We conclude by providing a novel suggestion for combining neuroimaging methods with embodied VR that relies on the suspension of disbelief.     

MAKING ROOM FOR MADNESS IN MENTAL HEALTH: THE IMPORTANCE OF ANALYTICALLY‐INFORMED SUPERVISION OF NURSES AND OTHER MENTAL HEALTH PROFESSIONALS

In this paper, I discuss the importance of psychoanalytically informed supervision and training of nurses and other professionals in mental health settings. Using examples from supervision groups I will illustrate how a psychoanalytic approach to mental health can complement other ways of thinking about practice and management. Psychoanalysis provides a framework for understanding the relationship between the internal world of the patients, the therapeutic relationship and the social system. I will also argue that this understanding helps to develop and maintain therapeutic factors while reducing the risk of damaging behaviour and beliefs.     

Les unités de soins intensifs psychiatriques (USIP) : expériences françaises et internationales

Psychiatric Intensive Care Units (PICU) propose a secure setting for patients with acute behavior disturbances who can not be managed in psychiatric general wards. Physical violence acts against patients or hospital staff, substance abuse, non-compliance for care and treatment, intensity of symptoms or absconding are frequent motives for admission. Patients are compulsorily detained in secure conditions. They are admitted from psychiatric facilities of a health area or by agreement between hospitals. Multidisciplinary working in psychiatric intensive care is essential, delivered by qualified staff. Care and treatment must be centered on the patient, multidisciplinary, intensive, comprehensive with an immediacy of response to critical situations. As length of stay should not exceed 2 months in duration, interface and liaison with original services of patients are important issues. In France, PICU exist notably at Cadillac, Lyon, Paris, Nice, Eygurande, Montpellier, Pau and Prémontré. These facilities appear as a missing level, an interesting alternative in mental health care system, between psychiatric general wards and maximum security hospitals. This paper reports the creation of a National Association of PICU in France, the existence of national minimum standards and international experiences.     

Effectiveness of virtual reality for pediatric pain distraction during i.v. placement.

The objective of this study was to test the efficacy and suitability of virtual reality (VR) as a pain distraction for pediatric intravenous (i.v.) placement. Twenty children (12 boys, 8 girls) requiring i.v. placement for a magnetic resonance imaging/computed tomography (MRI/CT) scan were randomly assigned to two conditions: (1) VR distraction using Street Luge (5DT), presented via a head-mounted display, or (2) standard of care (topical anesthetic) with no distraction. Children, their parents, and nurses completed self-report questionnaires that assessed numerous health-related outcomes. Responses from the Faces Pain Scale-Revised indicated a fourfold increase in affective pain within the control condition; by contrast, no significant differences were detected within the VR condition. Significant associations between multiple measures of anticipatory anxiety, affective pain, i.v. pain intensity, and measures of past procedural pain provided support for the complex interplay of a multimodal assessment of pain perception. There was also a sufficient amount of evidence supporting the efficacy of Street Luge as a pediatric pain distraction tool during i.v. placement: an adequate level of presence, no simulator sickness, and significantly more child-, parent-, and nurse-reported satisfaction with pain management. VR pain distraction was positively endorsed by all reporters and is a promising tool for decreasing pain, and anxiety in children undergoing acute medical interventions. However, further research with larger sample sizes and other routine medical procedures is warranted.
