Morningness–Eveningness and Risk Taking

ABSTRACT. Depending on individual differences in biological rhythms and diurnal preferences, people have long been described as either “larks” or “owls.” Larks and owls differ greatly in personality aspects, but from the behavioral perspective it is unclear whether they have significant differences in terms of risky behaviors. Whether morning types or evening types are consistently more risk-taking or risk-averse in different domains remains unknown. This study adopted a general American adult sample to systematically investigate the relationship between chronotype and individuals’ risky behaviors in different domains. By using different methods to measure risky behaviors in different domains, the current research obtained convergent results that morningness was negatively related only to financially risky behaviors for American adults. More specifically, by using the composite scale of morningness and the domain-specific risk attitude scale, Study 1 showed that for American adults, morning types were less likely than evening types to engage in financially risky behaviors (N = 212). In Study 2, after scenario-based methods were used to measure risky behavior, results showed that that participants engaged less in risky behaviors in the domains of gambling and investment (N = 187). A mediator test showed that the negative relationship between morningness and financially risky behaviors was partly mediated by individuals’ self-control ability (self-control scale, Study 1).     

Application of the rubber hand illusion paradigm: comparison between upper and lower limbs

The “rubber hand illusion (RHI)” is a perceptual illusion, which allows the integration of artificial limbs into the body representation of a person by means of combined visual and tactile stimulation. The illusion has been frequently replicated but always concerning the upper limbs. The present study verified an analog illusion that can be called the “rubber foot illusion” (RFI). In a conjoint experiment using both a rubber hand and a rubber foot, brushstrokes were applied to the respective real and rubber limb placed alongside the real one. However, only the artificial limb’s handling was visible. The brushstrokes were given either synchronously, with a delay of ±0.5 s, or without tactile stimulation of the real limb. Questionnaire data and the proprioceptive drift towards the rubber limb (determined by calling on the subjects to show where they locate their unseen limb) defined the illusion strength. Results revealed that the illusion was induced in both limbs with comparable strength, but only in the synchronous condition.     

Objecting (to) Infrastructure: Ecopolitics at the Ukrainian Ends of the Danube

Abstract

In southern Ukraine, two hydraulic infrastructures continue to exist despite environmentalist campaigns that have exposed them as fragile, broken, or unprofitable. The Danube–Dnister Irrigation Project, a Soviet mega-project that diverted water from the Danube and turned the Sasyk estuary into a reservoir, receives state funding despite a 1994 ban on its use for irrigation. The Bystre Shipping Canal, built in 2004 despite domestic and international opposition, is losing money but continues to operate. These cases exemplify the material politics of infrastructuring in which infrastructure is understood as an antagonistic process of assembling networks of humans and nonhumans rather than a fixed facility. This approach helps explain how the confluence of unruly coastal matters and the politics of expertise have facilitated the re-embedding of these shipping and irrigation infrastructures’ in bureaucratic networks. These cases show that obduracy and fragility, as well as visibility and invisibility—conditions that figure prominently in infrastructure studies—should be considered in terms of oscillation rather than as ontologically distinct or static conditions. This analysis highlights the limits of the modernist search for scientific certainty in resolving environmental conflicts in Ukraine, and some possibilities to experiment politically with new decision-making procedures. This account can thus point beyond reform impulses that re-enact modernist narratives of progress within a strict nature-society divide.

Intuitive Dualism and Afterlife Beliefs: A Cross-Cultural Study

It is widely held that intuitive dualism—an implicit default mode of thought that takes minds to be separable from bodies and capable of independent existence—is a human universal. Among the findings taken to support universal intuitive dualism is a pattern of evidence in which “psychological” traits (knowledge, desires) are judged more likely to continue after death than bodily or “biological” traits (perceptual, physiological, and bodily states). Here, we present cross-cultural evidence from six study populations, including non-Western societies with diverse belief systems, that shows that while this pattern exists, the overall pattern of responses nonetheless does not support intuitive dualism in afterlife beliefs. Most responses of most participants across all cultures tested were not dualist. While our sample is in no way intended to capture the full range of human societies and afterlife beliefs, it captures a far broader range of cultures than in any prior study, and thus puts the case for afterlife beliefs as evidence for universal intuitive dualism to a strong test. Based on these findings, we suggest that while dualist thinking is a possible mode of thought enabled by evolved human psychology, such thinking does not constitute a default mode of thought. Rather, our data support what we will call intuitive materialism—the view that the underlying intuitive systems for reasoning about minds and death produce as a default judgment that mental states cease to exist with bodily death.     

Irritability in Children and Adolescents With OCD

Irritability is a common, impairing transdiagnostic symptom in childhood psychopathology, though it has not been comprehensively studied in pediatric obsessive-compulsive disorder (OCD). Further, the central cognitive behavioral treatment component for OCD, exposure and response prevention therapy (ERP), has been recently proposed as a treatment for irritability. This study aimed to evaluate whether certain clinical characteristics are associated with irritability in pediatric OCD and whether irritability reduces following ERP. Participants were 161 youth (ages 7–17) with OCD and a caregiver participating in a randomized controlled trial of D-cycloserine or pill placebo augmented ERP. Participants completed validated assessments during treatment. Irritability was significantly and positively associated with depressive symptoms, defiance, functional impairment, and family accommodation, but was not associated with pretreatment OCD severity, symptom dimensions, obsessive beliefs. Irritability significantly declined following treatment, with over half of youth with any pretreatment irritability experiencing clinically significant change, though this change was not related to OCD improvement. Results suggest that irritability may be a marker of psychiatric comorbidity, parental accommodation, and impairment in youth with OCD. Implications for the exposure-based treatment of irritability are discussed.     

The Relationship between Intimate Partner Violence and Suicidal Ideation among Young Chinese,Korean, and Vietnamese American Women

ABSTRACT

High depression and suicide rates are critical problems that have a significant impact on the lives of young Asian American women. Intimate partner violence (IPV) has been identified as a predictor of suicidality in general female samples, but no research study has examined the relationship between IPV and suicidality in a sample of 1.5 and second-generation Chinese, Korean, and Vietnamese American women. We used data collected from 173 women (aged 18-35 years) who were screened for eligibility to participate in the development and efficacy study of Asian American Women’s Action for Resilience and Empowerment (AWARE). We measured the prevalence of (a) IPV, (b) lifetime suicidal ideation/intent, and (c) childhood abuse and tested the association between IPV and lifetime suicidal ideation/intent among study participants who completed the clinical screening assessments. The results indicated that seven out of 10 women in our sample experienced lifetime suicidal ideation/intent, psychological aggression was the most commonly reported form of IPV during the last six months, followed by sexual coercion, and history of physical and/or sexual partner violence had the most robust association with lifetime suicidal ideation/intent after controlling for demographic factors and childhood abuse. Our study suggests that suicide prevention and intervention programs for young 1.5 and second-generation Asian American women should not only address experiences of childhood abuse, but also incorporate culturally adapted behavioral health approaches to identify and target physical and sexual partner violence. Furthermore, any such programs need to integrate a systemic approach in addressing IPV within the context of various marginalized experiences of Asian American women.
