How to be a Normativist about the Nature of Belief

According to the normativist, it is built into the nature of belief itself that beliefs are subject to a certain set of norms. I argue here that only a normativist account can explain certain non‐normative facts about what it takes to have the capacity for belief. But this way of defending normativism places an explanatory burden on any normativist account that an account on which a truth norm is explanatorily fundamental simply cannot discharge. I develop an alternative account that can achieve explanatory adequacy where this sort of truth privileging account falls short.     

HPA-Axis Activation as a Key Moderator of Childhood Trauma Exposure and Adolescent Mental Health

Individual differences in a child’s sensitivity to stress may influence whether youth exposed to trauma develop symptoms of psychopathology. We examined the interaction between HPA-axis reactivity to an acute stressor and exposure to different types of childhood trauma as predictors of mental health symptoms in a sample of youth. Youth (n?=?121, ages 9–16; 47% female) completed a standardized stress task, including 5 post-stress salivary cortisol samples. Parents also completed the Child Behavior Checklist as a measure of child internalizing and externalizing symptoms in the past month, and completed the Early Trauma Inventory (ETI) as a measure of their child’s trauma exposure. More emotional abuse and non-intentional trauma were associated with greater internalizing symptoms. Youth exposed to physical abuse who demonstrated slower HPA-axis reactivity had elevated internalizing and externalizing symptoms. Youth exposed to emotional abuse or non-intentional traumatic events who demonstrated faster HPA-axis reactivity had elevated internalizing and externalizing symptoms. Profiles of exaggerated or attenuated HPA-axis reactivity to acute stress may be risk factors for psychopathology in children facing different stressful social environments.     

Implementing a Virtual Health Telemedicine Program in a Community Setting

Aurora Health Care in eastern Wisconsin has a clinical genetics program driven by genetic counselors in the cancer/adult and prenatal genetics settings. In 2015, the workforce shortage of genetic counselors left us with 4 open positions for genetic counselors that we were unable to fill. We explored many models of alternative service delivery, and determined virtual health (VH) via telemedicine to be the best option for our system. Historically, telemedicine technologies have been used to provide access to healthcare services to patients in remote areas. We, however, were struggling to find genetics counselors to staff both our remote clinics and urban clinics. To solve this problem, we recruited genetic counselors from across the country to work remotely from their current home or home office utilizing VH to staff our clinics. We then created clinical workflows and an implementation process of virtual health for 9 prenatal and cancer clinics across the eastern Wisconsin footprint of our healthcare system over the course of 12 months. Here we provide our experience and process in establishing a VH program in order to help other institutions that have been affected by the workforce shortage of clinical genetics professionals.     

Using self‐monitoring and differential reinforcement of low rates of behavior to decrease repetitive behaviors: A case study

We used a reversal design to evaluate the effects of a self‐monitoring system and differential reinforcement of low rates of behavior on decreasing repetitive body movements in a child with autism. A trial‐based functional analysis revealed that repetitive body movements were maintained by automatic reinforcement. Treatment consisted of teaching the participant to use a self‐monitoring system to monitor the occurrence of repetitive body movements. A stimulus control analysis revealed the self‐monitoring system acquired stimulus control over the repetitive body movements, in that they were more likely to occur in the absence of the system than in its presence. The self‐monitoring system was implemented with a differential reinforcement of low rates of behavior, and their combined effects were evaluated within a reversal design. Repetitive body movements decreased with the implementation of the treatment. The use of self‐monitoring systems to target problem behavior is discussed.     

Comparing implicit and explicit attitudes of gay,straight, and non-monosexual groups toward transmen and transwomen

Background: Transphobia studies have typically relied on self-report measures from heterosexual samples. However, there is evidence suggesting the need to use indirect measures and to explore transphobia among other populations. Aims: This study examined how explicit and implicit attitudes toward transwomen and transmen differ between people of different sexual orientations. Methods: Cisgender participants (N = 265) completed measures of explicit feelings toward transmen and transwomen, as well as Implicit Association Tests (IAT) for each group. Comparisons were made between 54 gay, 79 straight, and 132 non-monosexual (asexual, bisexual, pansexual) individuals. Results: An interaction was found between measurement type (explicit, implicit) and sexual orientation (straight, gay, non-monosexual). With regard to transmen, gay respondents’ explicit and implicit scores diverged such that they explicitly reported lower bias than their straight counterparts, but their Transmen-IAT showed an implicit preference for biological men over transmen. For attitudes toward transwomen, implicit measurement scores were consistently negative and did not differ by group. Gay participants also reported positive explicit attitudes toward transwomen, similar to non-monosexual people. Discussion: Overall, findings show that gay people tend to report positive attitudes toward transgender people explicitly, but tend to have implicit bias against both transmen and transwomen. Future studies need to explore the origins of these biases and how they relate to the complex interplay of sex, gender, and sexual orientation.     

Detecting random responders with infrequency scales using an error-balancing threshold

Infrequency scales are becoming a popular mode of data screening, due to their availability and ease of implementation. Recent research has indicated that the interpretation and functioning of infrequency items may not be as straightforward as had previously been thought (Curran & Hauser, 2015), yet there are no empirically based guidelines for implementing cutoffs using these items. In the present study, we compared two methods of detecting random responding with infrequency items: a zero-tolerance threshold versus a threshold that balances classification error rates. The results showed that a traditional zero-tolerance approach, on average, screens data that are less indicative of careless responding than those screened by the error-balancing approach. Thus, the de facto standard of applying a “zero-tolerance” approach when screening participants with infrequency scales may be too stringent, so that meaningful responses may also be removed from analyses. Recommendations and future directions are discussed.     

The influence of visual flow and perceptual load on locomotion speed

Visual flow is used to perceive and regulate movement speed during locomotion. We assessed the extent to which variation in flow from the ground plane, arising from static visual textures, influences locomotion speed under conditions of concurrent perceptual load. In two experiments, participants walked over a 12-m projected walkway that consisted of stripes that were oriented orthogonal to the walking direction. In the critical conditions, the frequency of the stripes increased or decreased. We observed small, but consistent effects on walking speed, so that participants were walking slower when the frequency increased compared to when the frequency decreased. This basic effect suggests that participants interpreted the change in visual flow in these conditions as at least partly due to a change in their own movement speed, and counteracted such a change by speeding up or slowing down. Critically, these effects were magnified under conditions of low perceptual load and a locus of attention near the ground plane. Our findings suggest that the contribution of vision in the control of ongoing locomotion is relatively fluid and dependent on ongoing perceptual (and perhaps more generally cognitive) task demands.
