Past,Present, and Future: Editorial on Virtual Reality Applications to Human Services

Abstract

“Virtual Reality” interventions in human services may include 360° video, augmented reality, mixed reality, and fully immersive 3-dimensional virtual reality simulations. A variety of applications have been evaluated in various fields of study, including medicine, social work, psychology, and human performance training. Currently, the state of research of VR interventions in human services has primarily focused on efficacy and effectiveness research, with few studies evaluating “scaling up” or implementation of VR interventions in larger populations. Unfortunately, the state of efficacy and effectiveness studies of VR interventions still remains weak with some applications due to smaller sample sizes, lack of randomized control trials, and a gap in reporting key intervention qualities, dosage, and outcomes. With new developments in combining artificial intelligence with VR, realism and the potential for human interaction with computer generated simulations may boost presence and immersion within these applications. This editorial provides an overview of the state of virtual reality applications in human service provision, potential gaps to be addressed by research in the future, and the development of AI based interactive sequences that may boost use presence.     

The process of coping with domestic violence in adult survivors of childhood sexual abuse

Research suggests that the use of disengaged or avoidant strategies to cope with interpersonal violence contributes to the development of depressive symptoms and other psychological difficulties. Survivors of childhood sexual abuse (CSA) who are exposed to subsequent episodes of abuse may be more likely to rely on disengaged coping strategies, placing them at elevated risk of psychological symptomatology. In this study, we explored the interrelationships between coping, depression, and self-esteem in an ethnically diverse sample of domestic violence survivors (N = 219) with and without a history of CSA. As predicted, CSA survivors (n = 86) reported significantly greater use of disengaged coping strategies (wishful thinking, self-criticism, and social withdrawal) than non-CSA survivors (n = 133). As hypothesized, both a CSA history and the use of disengaged coping significantly predicted higher levels of depression and lower self- esteem. Clinical implications of the findings are discussed.     

Evaluating the effect of education on earnings: models, methods and results from the National Child Development Survey

Summary.  Regression, matching, control function and instrumental variables methods for recovering the effect of education on individual earnings are reviewed for single treatments and sequential multiple treatments with and without heterogeneous returns. The sensitivity of the estimates once applied to a common data set is then explored. We show the importance of correcting for detailed test score and family background differences and of allowing for (observable) heterogeneity in returns. We find an average return of 27% for those completing higher education versus anything less. Compared with stopping at 16 years of age without qualifications, we find an average return to O-levels of 18%, to A-levels of 24% and to higher education of 48%.     

Up Versus Down: The Role of Intersensory Redundancy in the Development of Infants' Sensitivity to the Orientation of Moving Objects

According to the intersensory redundancy hypothesis (IRH), during early development, perception of nonredundantly specified properties is facilitated in unimodal stimulation as compared with bimodal stimulation. Later in development, attention becomes more flexible and infants can detect nonredundantly specified properties in both unimodal and bimodal stimulation. This study tested these predictions by assessing the development of infants' sensitivity to the orientation of an object striking a surface, information that is nonredundantly specified in visual and in audiovisual stimulation. Infants of 3, 5, and 8 months were habituated to unimodal visual or bimodal, synchronous, audiovisual films of a hammer tapping a rhythm in 1 of 2 orientations (upward vs. downward). Results demonstrated an Age × Condition interaction, where younger infants (3 and 5 months) detected the orientation change in unimodal but not bimodal stimulation, whereas older infants (8 months) detected the change in both types of stimulation. Further, in a control study, 3‐month‐olds detected the orientation change when bimodal stimulation was asynchronous, demonstrating that temporal synchrony impaired performance in the bimodal condition. These findings converge with those of prior studies and support predictions of the IRH.     

Qualitative Health Research with Children

The authors of this article identify and discuss some of the practical and ethical issues of qualitative research with children. The problems are illustrated through a research study about children's experience of asthma, and the way in which they perceive and interpret their condition. It is shown that social research with children has inherent difficulties relating to access, ethical and developmental issues. Researchers do not only have to gain parental permission but also want the child to enter the research voluntarily. Because of the children's stage of development and the asymmetrical relationship between researcher and informants, adequate safeguards and awareness of these problems are essential.     

The Bayesian choice of crop variety and fertilizer dose

Recent contributions to the theory of optimizing fertilizer doses in agricultural crop production have introduced Bayesian ideas to incorporate information on crop yield from several environments and on soil nutrients from a soil test, but they have not used a fully Bayesian formulation. We present such a formulation and demonstrate how the resulting Bayes decision procedure can be evaluated in practice by using Markov chain Monte Carlo methods. The approach incorporates expert knowledge of the crop and of regional and local soil conditions and allows a choice of crop variety as well as of fertilizer level. Alternative dose–response functions are expressed in terms of a common interpretable set of parameters to facilitate model comparisons and the specification of prior distributions. The approach is illustrated with a set of yield data from spring barley nitrogen–response trials and is found to be robust to changes in the dose–response function and the prior distribution for indigenous soil nitrogen.     

Development of Reasoning and the Tension between Scientific and Conversational Inference

We report two studies designed to examine the role of conversational understanding in young children's scientific reasoning. The results indicate that performance can be influenced by the degree of specificity in questioning. Under nonspecific questioning, accurate reasoning was associated with both vocabulary comprehension and pragmatic ability whereas under specific questioning it was associated only with vocabulary comprehension. Findings are discussed in terms of the conversational knowledge that is required for success on measures of scientific reasoning.     

Loosening the Soil of Their Thinking: A Theoretical Integration for Contracting with Low-Income Single Mothers to Stop Physical Aggression Toward Their Children

Clinical social work with low-income single mothers at-risk for physical abuse of their children traverses multiple theoretical perspectives for viewing causality and intervention in order to prevent future abuse. Cognitive-behavioral and psychodynamic approaches have figured prominently in the discourse but are often considered as opposing viewpoints. In this paper, narrative excerpts from a study about social workers’ experiences in developing working alliances with these women are used to suggest an integrative theoretical viewpoint for contracting with them to refrain from hitting their children.
