Designing Graphs to Communicate Risks: Understanding How the Choice of Graphical Format Influences Decision Making

Previous research suggests that the choice of graphical format for communicating risk information affects both understanding of the risk magnitude and the likelihood of acting to decrease risk. However, the mechanisms through which these effects work are poorly understood. To explore these mechanisms using a real‐world scenario, we examined the relative impact of two graphical displays for depicting the risk of exposure to unexploded ammunition during potential land redevelopment. One display depicted only the foreground information graphically (a bar graph of the number of people harmed), and a second depicted the foreground and background graphically (a stacked bar graph representing both the number harmed and at risk). We presented 296 participants with either the foreground‐only or the foreground and background graphical display and measured a broad set of outcome variables, examining (1) the graphical display effect on each of the outcome measures and (2) the pathways by which any display effects work to influence decision making. We found that the foreground‐only graphical display increased perceived likelihood and experienced fear, which produced greater worry, which in turn increased risk aversion. In addition, a positive evaluation of the communication materials increased support for policies related to land redevelopment, whether those policies were risk taking or risk mitigating. Finally, the foreground‐only graphical display decreased understanding of the risk magnitude, showing that approaches to accomplish one risk communication goal (promoting risk‐averse decisions) may do so at the expense of another goal (increasing understanding).     

“Just Like I'm Saving Money in the Bank”: Client Perspectives on Care Coordination Services

Older adults face many challenges to community living. The literature has not sufficiently explored the roles of care coordination in the maintenance of housing and access to health care among older adults, particularly from their own perspectives. This qualitative study analyzes the findings from 25 interviews and 6 focus group discussions (48 participants) with a multiethnic sample of older adults in the New York City area. Care coordination services appear to assist older adults access health care, and to a lesser extent, maintain affordable housing. Disparities in access to care coordination appear to remain for immigrant, minority and suburban populations.     

Revisiting the biological perspective in the use of biopsychosocial assessments in social work

ABSTRACT

The call for increased attention to the biopsychosocial perspective in social work practice is now decades old in the USA. And yet the challenge of teaching and learning from this perspective for those with limited background in biology calls for more inter-disciplinary examples to assist students with the process of engaging in theory-informed practice. In addition to identifying the key elements of human biology, this review of the literature focuses on four examples of client behaviors that receive little or no attention in most current textbooks on the inter-disciplinary nature of human behavior in the social environment; namely, the psychobiology of sleep, the sociobiology of eating, the neurobiology of post-partum depression, and the behavioral endocrinology of menopause. This review concludes with implications for practice.     

Infants' ERP Responses to Novel and Familiar Stimuli Change Over Time: Implications for Novelty Detection and Memory

Detection of novelty is an important cognitive ability early in development, when infants must learn a great deal about their world. Work with adults has identified networks of brain areas involved in novelty detection; this study investigated electrophysiological correlates of detection of novelty and recognition of familiarity in 9‐month‐old infants, using event‐related potentials (ERPs). Infants were familiarized with an event in the laboratory, then ERPs were recorded as they viewed repeated presentations of pictures of this familiar event and a novel event, along with single presentations of 30 trial‐unique events. A middle‐latency negative component was sensitive to degree of novelty, differing in amplitude and latency by stimulus condition and across repeated presentations. Long‐latency slow‐wave activity also related to stimulus condition. Findings have implications for our understanding of infants' detection of novel information and the processes that render the novel familiar.     

Diverse Pathways of Psychology Majors: Vocational Interests,Self‐Efficacy,and Intentions

The authors examine the differences in vocational interests and self‐efficacy of 254 undergraduate psychology majors organized by 7 career intention groups (e.g., psychological research). The explanatory power of individual General Occupational Themes (GOTs), Basic Interest Scales (BISs), and Personal Style Scales (PSSs) of the Strong Interest Inventory (L. W. Harmon, J. C. Hansen, F. H. Borgen, & A. L. Hammer, 1994) and the General Confidence Themes (GCTs) of the Skills Confidence Inventory (N. E. Betz, F. H. Borgen, & L. W. Harmon, 1996) is examined. Results show overall group differences in Holland themes. The BISs, PSSs, and GCTs appear to augment GOTs when used with clients considering psychology or other fields with diverse pathways.

Experiences of student veterans with social anxiety and avoidance: A qualitative study

Eight-to-ten percent of returning combat veterans report symptoms of Posttraumatic Stress Disorder (PTSD), of which 7–13% also report symptoms of Social Anxiety Disorder. Both disorders are characterized by maladaptive patterns of social functioning, which can have significant effects on the lives of returning combat veterans and increase suicidal risk. The objective of the present study was to identify elements of the lived experience of college student veterans experiencing social anxiety and avoidance. Twelve student veterans with post-9/11 active duty service were interviewed about their lived experiences with social anxiety/avoidance within the framework of phenomenological theory. Data was analyzed using multilevel coding and theme analysis. Analysis of interview themes (n = 12) clarified university campus environments that induce social anxiety/avoidance and the impact on personal and professional relationships, learning, and navigation of physical space. Implications of this study include addressing student veterans’ needs through clinical intervention and further representative research on prevalence rates of these risk factors in various university and community college settings.
