Intellectual humility and religious tolerance

Abstract

The present study explored the relationship between (a) intellectual humility toward religious beliefs and values and (b) religious tolerance. Pastors who identified as Christian (N = 196) completed measures of conservatism, religious commitment, intellectual humility toward religious beliefs and values, and religious tolerance. Intellectual humility was a positive predictor of religious tolerance, even when controlling for conservatism and religious commitment. An interaction was found between exposure to religious diversity and intellectual humility, such that exposure to religious diversity was positively related to religious tolerance only for participants who reported high levels of intellectual humility. We conclude by discussing limitations, areas for future research, and implications for interfaith dialog and engagement.     

Elemental and non-elemental olfactory learning in Drosophila

Brain complexity varies across many orders of magnitude between animals, and it is often assumed that complexity underpins cognition. It is thus important to explore the cognitive capacity of widely used model organisms such as Drosophila. We systematically investigated the fly’s ability to learn discriminations involving compound olfactory stimuli associated with shock. Flies could distinguish binary mixtures (AB+ CD-), including overlapping mixtures (AB+ BC-). They could learn positive patterning (AB+ A- B-) but could not learn negative patterning (A+ B+ AB-) or solve a biconditional discrimination task (AB+ CD+ AC- BD-). Learning about the elements of a compound (AB+) was not affected by prior conditioning of one of the elements (A+ AB+): flies do not exhibit blocking in this task. We compare these results with the predictions from simulation of several well-known theoretical models of learning, and find none are fully consistent with the overall pattern of observed behaviour.     

An inversion effect modified by expertise in capuchin monkeys

The face inversion effect may be defined as the general impairment in recognition that occurs when faces are rotated 180°. This phenomenon seems particularly strong for faces as opposed to other objects and is often used as a marker of a specialized face-processing mechanism. Four brown capuchin monkeys (Cebus apella) were tested on their ability to discriminate several classes of facial and non-facial stimuli presented in both their upright and inverted orientations in an oddity task. Results revealed significantly better performance on upright than inverted presentations of capuchin and human face stimuli, but not on chimpanzee faces or automobiles. These data support previous studies in humans and other primates suggesting that the inversion effect occurs for stimuli for which subjects have developed an expertise.     

Evaluating Merger and Intersection of Equivalence Classes with One Member in Common

Sidman (1994) noted that the existence of a member that is common to more than one class may produce either class merger (union) or class intersection. A multiple-selection, matching-to-sample test was developed to examine the conditions under which these outcomes occur. Test trials each required three conditional discriminations involving selection or rejection of comparison stimuli under control of samples representing two categories. Test results obtained from an initial group of typical adults using familiar stimuli (DOG and BIRD, pictures of dogs and birds and relevant printed breed names (e.g., DALMATIAN, RETRIEVER) showed the conditional stimulus control best described as intersection. For example, the word DALMATIAN provided the context for selecting the dalmatian but not the retriever picture. However, these results may have depended on the participants'' verbal history as English speakers. Would conditional-discrimination training with overlapping sets of laboratory-generated stimuli also result in intersection? Naïve typical adults were assigned to one of three different training conditions. Like the participants tested with familiar stimuli, these participants demonstrated highly reliable test outcomes best described as showing class intersection, regardless of training condition. These findings begin to elucidate the necessary and sufficient conditions for establishing complex category-like classes of stimuli.     

Attenuating memory distrust in a repeated checking task

Repeated checking has been demonstrated to lead to reductions in memory confidence in several previous studies using student and clinical samples. This process of reduced confidence in memory and detail for memory, are thought to arise from the inhibition of perceptual processing that develops during repeated checking. Our research investigated whether reduced memory confidence from repeated checking could be attenuated through the use of novel stimuli during the repeated checking task. Three groups were generated through random assignment of 65 undergraduate students. As seen in previous research, individuals who repeatedly checked a stimulus (a virtual stovetop) showed reduced memory confidence, vividness, and detail, when compared with individuals who repeatedly checked a different stimulus. A third group in which the colour of the repeatedly-checked stovetop changed every five trials showed no significant decline in memory confidence between the pre-test and post-test. Results suggest that increased memory distrust can be ameliorated through the use of stimuli with characteristics that are novel and distinctive. Findings are discussed in the context of the existing model of repeated checking and memory confidence, and implications for treatment methods are presented.

Results of a Randomized Controlled Trial of the Student Success Skills Program on Grade 5 Students’ Academic and Behavioral Outcomes

A randomized controlled trial of Student Success Skills (SSS) was conducted to determine the effect of the classroom program on Grade 5 students’ (N = 4,305) standardized test scores and proximal socioemotional variables associated with academic achievement. The SSS program was delivered by school counselors and reinforced through cuing and coaching by classroom teachers, which reflects the advocating student‐within‐environment approach to school counseling (Lemberger‐Truelove & Bowers, 2018). Hierarchical linear modeling analyses revealed the SSS program affected the treatment students’ behavioral engagement, disruption, assertion, cooperation, and test anxiety but did not result in a statistically significant difference on the participants’ reading and mathematics test scores. Implications for practice and further research are discussed.     

Sleep-Related Problems in Pediatric Obsessive-Compulsive Disorder and Intensive Exposure Therapy

Limited research has examined sleep-related problems (SRPs) among children and adolescents with obsessive-compulsive disorder (OCD). The present study addresses this gap by investigating preliminary associations between SRPs, demographic factors (gender and age), family variables (family accommodation and parental stress), and clinical factors (medication status, internalizing and externalizing symptoms, OCD severity, OCD-related impairment), and treatment outcomes in a sample of 103 youth (aged 7 to 17 years; 53% female) with a primary diagnosis of OCD. Clinician, parent, and child measures were used to assess demographic, family, and clinical predictors. SRPs were assessed using an 8-item measure comprising items of the Child Behaviour Checklist, Child Depression Inventory, and Multidimensional Anxiety Scale for Children as used in previous studies. Results showed that SRPs were highly prevalent among this sample and that more SRPs were associated with younger age, internalizing problems, and functional impairment. However, SRPs were not an independent predictor of OCD severity, impairment, or treatment response. Preliminary findings suggest that SRPs among youth with OCD may be more strongly associated with broader internalizing symptoms than with OCD itself. Future longitudinal research is warranted to further explore the complexity of SRPs when co-occurring with pediatric OCD.     

Self-reported changes in subjective health and anthrax vaccination as reported by over 900 Persian Gulf War era veterans

A 1999 study of United Kingdom servicemembers by Unwin, et al. recently found significant relationships between anthrax and other vaccinations, reactions to those vaccines, and later health problems for male current or former active military Gulf War veterans. Likewise, in 2000 Steele and in 1998 Gilroy found possible adverse effects of vaccinations on Gulf War veterans. However, the role of such vaccinations remains controversial; more recent government reports continue to dispute the existence of any data that might reflect adversely on the role of vaccinations on the health of Gulf War veterans. To address this controversy, the current study assessed similar relationships for over 900 Reserve Component Gulf War Era veterans from Ohio and nearby states. Gulf War veterans were more likely to report poorer health than non-Gulf veterans. Female veterans were more likely to report mild or severe reactions to vaccines than male veterans. Those veterans who received anthrax vaccine reported more reactions to vaccines than those who did not receive anthrax vaccine. Declines in long-term subjective health were associated with receipt of anthrax vaccine by Gulf War veterans but not for those who did not deploy to the Gulf, although few of the latter received anthrax vaccine. Regardless of deployment status, veterans who reported more severe reactions to vaccines were more likely to report declines in subjective health. Female veterans reported poorer health during the Gulf War than did male veterans, but sex was not related to veterans' reports of subjective health at subsequent times. It is recommended that servicemembers who experience severe reactions to anthrax vaccine be medically reevaluated before receiving further anthrax vaccine and that careful follow-ups be conducted of those receiving the vaccine currently, in accordance with Nass's 1999 recommendations. We also recommend that safer alternatives to thimerosal (a mercury sodium salt, 50% mercury) be used to preserve all vaccines.     

Additive impact of childhood emotional,physical, and sexual abuse on suicide attempts among low-income African American women

This study examines the association between exposures to multiple forms of childhood abuse (emotional, physical, sexual) and adult suicidal behavior in a sample of low-income, African American women. We hypothesized a linear relation between childhood abuse and risk for making a suicide attempt, such that the more forms of childhood abuse to which a woman was exposed, the greater her risk would be to make a suicide attempt. Logistic regression analyses revealed that, compared to women who did not report any experiences of childhood abuse, women who experienced one, two, or three forms of abuse were 1.83, 2.29, or 7.75 times more likely to attempt suicide, respectively (all statistically significant). Furthermore, compared to women who reported one or two types of abuse, women who reported all three types of abuse were statistically more likely to attempt suicide. These findings have implications for clinicians working with African American women who report either childhood abuse or exhibit suicidal behavior.
