The impact of mediodorsal thalamic lesions on olfactory attention and flavor perception

Olfactory attention may be important in generating odor-induced tastes - an arguably universal form of synesthesia - by ensuring that the taste concurrent is captured by the nose and olfaction, not by the mouth and gustation (oral-capture). To examine the role of olfactory attention in generating odor-induced tastes and oral capture we tested a small sample (n = 4) of participants with likely impairments in olfactory attention - individuals with mediodorsal thalamic nucleus (MDNT) lesions. These participants were compared to two sets of controls on tests of olfactory attention, oral capture, odor and flavor perception, and control tasks. MDNT participants demonstrated impaired olfactory attention and enhanced oral capture. Greater oral capture was associated with greater olfactory attentional impairment. These findings imply that olfactory attention may be important in attributing odor-induced tastes to the olfactory modality. However, unlike for visual binding and for the neurodevelopmental synesthesias, where attention may be necessary to demonstrate both phenomena, olfactory attention deficits did not impair flavor binding or the experience of odor-induced tastes.     

THE USE OF BEHAVIORAL ASSESSMENT TO PRESCRIBE AND EVALUATE TREATMENTS FOR SEVERELY HANDICAPPED CHILDREN

Behavioral assessment procedures were used to prescribe and evaluate treatments of maladaptive behavior for 2 children with severe multiple handicaps. In Experiment 1, the results of an assessment of reinforcer preference were used in conjunction with a functional analysis of the conditions maintaining self-injurious behavior to prescribe a treatment for a child with severe disabilities. The treatment procedure involved the use of a pressure-sensitive microswitch to activate reinforcing stimuli during two solitary conditions, during which self-injurious behavior had occurred at high rates. The results were evaluated with a multiple baseline across settings design and indicated that self-injury decreased with concomitant increases in microswitch activation. Results were maintained at 6 weeks, 8 weeks, and 6 months. In Experiment 2, the results of behavioral assessments of reinforcer preference and self-injurious behavior were combined to develop a treatment for a second severely handicapped child, who exhibited high rates of self-injury in demand situations. This treatment was evaluated with a multiple baseline across tasks design and resulted in the elimination of self-injury for up to 15 months.     

Familiar idiom comprehension

Sentences containing idioms used either literally or figuratively were presented repeatedly for 100 msec per presentation. Half of the sentences were preceded by a paragraph. The number of presentations required to read the sentences and cued recall of the sentences were recorded. The serial brief presentations method provided predictable and meaningful results. Sentences containing idioms used literally required more presentations than those containing idioms used figuratively. Cued recall was better for idioms used literally than for those used figuratively. These results are interpreted as support for the Idiomatic Processing Model of idiom comprehension, which suggests that the figurative meaning is processed first; only if that one is inappropriate is the literal meaning processed.     

Cultural worldviews and climate change: A view from China

We investigated the association between cultural worldviews and climate change risk perceptions, support for climate friendly policies and climate change mitigation behaviours in a large Chinese sample. Items from Dake's cultural theory scales and Kahan's cultural cognition scale were presented to a Qualtrics online panel consisting of 515 Mandarin‐speaking residents of Beijing. A series of factor analyses revealed that the combined item sets were best represented by four‐dimensions: hierarchism, individualism, egalitarianism and fatalism. Mediation analysis revealed that respondents with egalitarian and non‐fatalist worldviews perceived greater risk associated with climate change, which in turn predicted greater support for policies to manage climate change and increased mitigation behaviour. In addition, respondents who scored high on individualism were less likely to support climate change policies, but this effect was not mediated by risk perceptions. Overall, our results suggest cultural worldviews may influence policy support both directly and indirectly through risk perceptions.     

The Politics of Teaching of Indigenous Traditions in Aotearoa/New Zealand

Reflecting on two study abroad trips to New Zealand in 2005 and 2007, I suggest in this essay that it is possible to mitigate the risk of (American or European) students recapitulating imperial attitudes through development of a rigorous curriculum focusing on the legacies of colonialism, institutional racism, and the somewhat dubious phenomenon of “post‐colonialism.” Readings, I argue, should be in continual play during cultural and social activities, operating in a dialectal move toward an “ethics of respect.” Such an ethics remains aporetic, or uncertain, insofar as no code of behavior can render us immune to the political and polemical effects of past and present forms of imperialism. However, a cultivated respect for distance and difference, including regarding questions of “authenticity,” can help to actualize the transformative promise of studying (indigenous) religion abroad. This essay is published alongside of six other essays, including a response from John Barbour, comprising a special section of the journal (see Teaching Theology and Religion 18:1, January 2015).     

Using Coaching to Support Teacher Implementation of Classroom-based Interventions

Despite the growing evidence base for the efficacy of preventive interventions, the level of implementation of these interventions in schools is often less than optimal. One promising approach to supporting teachers in implementation of interventions is the use of coaching. In this study, teachers were trained in a universal classroom management intervention and provided ongoing coaching. The association between the type and amount of coaching activities and teacher implementation of proactive classroom management over time were investigated. Results indicated that teachers who received more performance feedback had higher levels of implementation over time in comparison with teachers who received less feedback. In addition, a significant interaction between the amount of coaching a teacher received and his or her implementation of proactive classroom management was found. Increased implementation over time was observed for teachers with lower initial levels of implementation who received more coaching, whereas implementation decreased over time for teachers who received less coaching. The importance of coaching as a support system for enhancing implementation quality of classroom-based preventive interventions is discussed.     

Perspectives from the Edge: Chaplains in Greater Boston, 1945–2015

We follow Bender et al.’s (Religion on the Edge: De‐Centering and Recentering the Sociology of Religion) call to study religion “on the edge” by looking at the work of chaplains, religious professionals who work outside of congregations. Rather than studying chaplains within a single type of institution—the military, healthcare, or other sectors—we shift the unit of analysis to geography, asking where chaplains in Greater Boston worked between 1945 and the present. Based on coverage in the Boston Globe, we find that chaplains, mostly men, worked across Greater Boston between 1945 and 2015. The majority were Catholic with frequent minorities of Protestants and Jews, and—after 1995—a few Buddhists, Muslims, and Humanists. Most worked in higher education, healthcare, and prisons. While much of the chaplains’ work seems improvisational and varied, we identify services related to ceremonies, bearing witness, and working around death as common occurrences across the venues where chaplains worked. To the extent that these patterns are evident in other cities, they suggest that chaplains have regularly been a quiet part of the religious landscape, that they are a consistent part of the institutional field, and that their work has more commonalities across sectors than previous studies suggest.     

Cumulative Risk,Emotion Dysregulation,and Adjustment in South African Youth

Research on cumulative risk is growing, however, little work has occurred in low- or middle-income countries, and few studies have focused on processes linking risk to outcomes. This study explored relations between components of cumulative risk and adjustment in a sample of 324 South African youth (M age?=?13.11 years; SD?=?1.54 years; 65% female; 56% Black/African; 14% Colored; 23% Indian; 7% White), and tested competing models of emotion dysregulation as a mediator or moderator of risk—adjustment links. Data was collected from youth and their female caregivers during home interviews. Structural equation models and regression analyses accounting for age and sex contributions revealed that emotion dysregulation mediated associations between sociodemographic risk and internalizing symptoms, externalizing problem behavior, and drug use severity, and moderated links between psychosocial risk and internalizing symptoms and externalizing problem behavior. For the mediator models, sociodemographic risk was associated with impaired emotion regulation, which in turn was linked with heightened adjustment difficulties. For the moderator models, psychosocial risk was linked with adjustment problems only when emotion dysregulation was high. These data indicate the importance of disentangling components of cumulative risk. Future research within the South African cultural context might build on these findings by adapting and testing school- or family-based prevention or intervention programs that include modules on emotion regulation.     

Investigating the effectiveness of brief cognitive reappraisal training to reduce fear in adolescents

As adolescent anxiety is common and costly, identifying effective strategies to reduce symptoms is a priority. This study tested whether adolescents could learn to use cognitive reappraisal strategies to attenuate fear during extinction learning. Fifty-seven participants (12–15 years) viewed images of two neutral faces, one which was paired with a fearful expression and shrieking scream (conditioned threat stimulus) and the other that was never paired with the aversive outcome (conditioned safety stimulus) during fear acquisition. Before extinction, participants either received cognitive appraisal training, which explored alternative, benign meanings associated with the scream or a control activity. Self-reported fear ratings in the cognitive reappraisal group were significantly lower to both the conditioned threat and safety stimuli after extinction than the control group. These findings did not characterise fear-potentiated startle data. Potential reasons for the lack of consistency between measures are considered.
