    A contextual behavioral approach to the study of (persecutory) delusions

    Throughout the past century the topic of delusions has mainly been studied by researchers operating at the mental level of analysis. According to this perspective, delusional beliefs, as well as their emergence and persistence, stem from an interplay between (dysfunctional) mental representations and processes. Our paper aims to provide a starting point for researchers and clinicians interested in examining the topic of delusions from a functional-analytic perspective. We begin with a brief review of the research literature with a particular focus on persecutory delusions. Thereafter we introduce Contextual Behavioral Science (CBS), Relational Frame Theory (RFT) and a behavioral phenomenon known as arbitrarily applicable relational responding (AARR). Drawing upon AARR, and recent empirical developments within CBS, we argue that (persecutory) delusions may be conceptualized, studied and influenced using a functional-analytic approach. We consider future directions for research in this area as well as clinical interventions aimed at influencing delusions and their expression

    Too sick to drive : how motion sickness severity impacts human performance

    There are multiple concerns surrounding the development and rollout of self-driving cars. One issue has largely gone unnoticed - the adverse effects of motion sickness as induced by self-driving cars. The literature suggests conditionally, highly and fully autonomous vehicles will increase the onset likelihood and severity of motion sickness. Previous research has shown motion sickness can have a significant negative impact on human performance. This paper uses a simulator study design with 51 participants to assess if the scale of motion sickness is a predictor of human performance degradation. This paper finds little proof that subjective motion sickness severity is an effective indicator of the scale of human performance degradation. The performance change of participants with lower subjective motion sickness is mostly statistically indistinguishable from those with higher subjective sickness. Conclusively, those with even acute motion sickness may be just as affected as those with higher sickness, considering human performance. Building on these results, it could indicate motion sickness should be a consideration for understanding user ability to regain control of a self-driving vehicle, even if not feeling subjectively unwell. Effectiveness of subjective scoring is discussed and future research is proposed to help ensure the successful rollout of self-driving vehicles

    Oil possibilities in Western Kansas and North Central Wyoming

    The reported discover of oil in the McNab well in the northwest corner of Trego County, Kansas, has attracted attention to that region as possible oil producing territory. The offer of certain blocks of leases on several so-called oil structures occasioned the reconnaissance made by the writer. The prospects were examined during the period, September 28 to October 14, 1921 --page 1

    Understanding Adolescent Friendships: An Analysis of the Role of Social Perspective-Taking in Friendship Dissolutions

    Get PDF
    Friendships are critical relationships in adolescence, however, many friendships dissolve. One construct that may play a role in how adolescents experience such dissolutions is social perspective-taking (SPT). To test this hypothesis, 354 middle-schoolers (Mage=11.89, SD=0.86; 53% female; 82% white) completed a self-report, online survey regarding a dissolution experience. Results from an independent samples t-test revealed that females (M=2.45, SD=0.70) displayed higher SPT than males (M=2.09, SD=0.73), t(270)=-4.13, p\u3c0.001. A correlational analysis confirmed our hypothesis that adolescents who showed greater SPT would report higher quality friendships, r(271)=0.593, p\u3c0.001. Contrary to our hypothesis, adolescents who displayed higher SPT were more likely to react with anger (r(257)=0.16, p\u3c0.001), sadness (r(252)=0.31, p=0.01), loneliness (r(253)=0.28, p\u3c0.001), and rumination (r(252)=0.23, p\u3c0.001), and less likely to feel happy (r(259)=-0.29, p\u3c0.001) and relieved (r(255)=-0.26, p\u3c0.001) following a dissolution. These results aid in the understanding of social perspective-taking and its meaning in adolescent relationships and social development.https://digitalcommons.cortland.edu/slides/1003/thumbnail.jp

    A social-cognitive model of trait and state levels of gratitude.

    Get PDF
    Three studies tested a new model of gratitude, which specified the generative mechanisms linking individual differences (trait gratitude) and objective situations with the amount of gratitude people experience after receiving aid (state gratitude). In Study 1, all participants (N = 253) read identical vignettes describing a situation in which they received help. People higher in trait gratitude made more positive beneficial appraisals (seeing the help as more valuable, more costly to provide, and more altruistically intended), which fully mediated the relationship between trait and state levels of gratitude. Study 2 (N = 113) replicated the findings using a daily process study in which participants reported on real events each day for up to14 days. In Study 3, participants (N = 200) read vignettes experimentally manipulating objective situations to be either high or low in benefit. Benefit appraisals were shown to have a causal effect on state gratitude and to mediate the relationship between different prosocial situations and state gratitude. The 3 studies demonstrate the critical role of benefit appraisals in linking state gratitude with trait gratitude and the objective situation
