The impact of religious cognitive behavioural therapy (RCBT) on general health among Iranians

The aim of this study was to determine the efficacy of religious cognitive behavioural therapy (RCBT) on general health among Iranians. This study was a randomised, single-blinded clinical trial from April 2017 to October 2017. One hundred forty-four Yazd citizens were selected using a cluster sampling method and randomly assigned to experimental or control groups. The experimental groups received 10 sessions of RCBT, lasting 45 minutes once a week and the control group remained on the waiting list. The results showed that mean general health scores in the experimental groups were significantly lower than those in the control group on the post-test. RCBT had the most positive impact on somatic symptoms, anxiety/insomnia, social dysfunction, depression, and mental health. Based on these findings RCBT can be considered a significant and effective practical therapy for improving both general and psychological health.     

Motion-induced overestimation of the number of items in a display

Subjects were asked to report the number of items in a display as the items moved along a circular path around the fixation point. As the rotation speed increased, the apparent number of items also increased. This motion-induced overestimation (MIO) effect was investigated in three experiments. In the first experiment, the effect of rotation speed and set size was explored with an enumeration task. The overestimation error increased with an increase in speed or number of items in the display. In the second experiment, we used an adjustment paradigm to measure the speed threshold of MIO effect onset. Temporal rate of the display, which was defined as product of rotation speed and the number of rotating items, was the determining factor of MIO onset. In the third experiment, moving items were marked with different colours. Surprisingly, the number of perceived items was still overestimated even though the number of perceived colours was not.     

Perceptual Load And Visuocortical Processing: Event-Related Potentials Reveal Sensory-Level Selection

Behavioral evidence suggests that the processing of parafoveal stimuli decreases as the perceptual demands of a task at fixation increase. However, it remains unclear whether or not this effect of perceptual load occurs during initial sensory-level processing at early stages of visuocortical analysis. Using event-related potential measures, we found that increasing the perceptual load of foveal targets led to a significant decrease in the sensory-evoked response to parafoveal stimuli. Moreover, these effects were observed using two different operational definitions of perceptual load. This result indicates that perceptual load affects the flow of information during the initial stages of visuocortical processing.     

Co-Occurring Youth Profiles of Adverse Childhood Experiences and Protective Factors: Associations with Health,Resilience, and Racial Disparities

It is important to understand racial/ethnic differences in adverse childhood experiences (ACEs), given their relationship to long-term physical and mental health, and the public health cost of the significant disparities that exist. Moreover, in order to inform interventions and promote resilience, it is critical to examine protective factors that mitigate the relationship between adversity and poor health. The current study utilized latent transition analyses (LTA) to examine co-occurring profiles of ACEs and protective factors (from school, family, and community contexts) and links to health outcomes among 30,668 Black (10.4%), Latinx (12.3%), and White youth (77.3%) ages 12–17 (52.5% male) who participated in the 2011–12 National Survey of Children's Health (NSCH). Results suggested that greater adversity was associated with worse health, while more access to protective factors was associated with better health. White youth had consistently lower endorsement of ACEs, greater access to protective factors, and better health compared to their Black and Latinx counterparts. Efforts to improve child health and racial/ethnic disparities in research and practice must consider adversity, protective factors, and the systemic inequities faced by racial/ethnic minority youth in the United States.     

Longitudinal Patterns of Self-Regulation among Ethnic Minority Children Facing Poverty

Early poverty is associated with a cumulative load of family and community risk factors that can impact the development of self-regulatory abilities and result in socio-emotional and achievement gaps which begin early and persist across the lifespan. Ethnic minorities are disproportionately represented among children living in poverty. The longitudinal trajectories of self-regulation are important to understand in this population, in order to best inform prevention efforts. This study examines patterns of self-regulation over time among young, ethnic minority children living in low income, urban households. A stratified, random sample of 555 children, ages 2 to 4 years, (46% Black, 46% Hispanic; 47% female) were followed over three waves (including 1 and 5 year follow-ups). Internalizing and externalizing behaviors at approximately age nine were predicted by children’s early self-regulation. Latent class analyses revealed low, medium, and high levels of self-regulatory abilities at wave 1 (mean age: 2.99, SD?=?.81) and low and high levels, 1 year later (mean age: 4.39 (SD?=?.94). A gender effect was found whereby girls were more likely than boys to be in the high self-regulation class relative to the low at both waves. Using Latent Transition Analysis, distal outcomes were examined approximately 5 years after the initial assessment (mean age: 8.83, SD?=?.93). Children who sustained a higher level of self-regulation over time had the lowest internalizing and externalizing behaviors. Transition to low self-regulation at wave 2, regardless of initial self-regulation status, was related to greater severity of internalizing symptoms. Implications for prevention and future research are discussed.     

Religiosity and Subjective Wellbeing in Canada

Using the Canadian Ethnic Diversity Survey, I explore how religiosity associates with self-reported levels of wellbeing. The overall association of religious intensity with subjective wellbeing is found to be statistically significant, positive and small. When the impact is allowed to vary by religious group, it appears that Catholics and Protestants are very similar in how religiosity impacts their subjective wellbeing; the association is statistically significantly stronger for Canadian Muslims; and Canadian Jews are the closest group to religious nones. Surprisingly, among different dimensions of religious commitment, the intensity of religious belief is found to be the driver of the overall positive association, across religious groups. Finally, when Canadian population is divided into linguistic groups, religious involvement emerges as a negative predictor of French Canadians’ subjective wellbeing.     

Visual skills involved in decision making by expert referees

Previous studies have compared visual skills of expert and novice athletes; referees' performance has not been addressed. Visual skills of two groups of expert referees, successful and unsuccessful in decision making, were compared. Using video clips of soccer matches to assess decision-making success of 41 national and international referees from 31 to 42 years of age, 10 top referees were selected as the Successful group and 10 as the Unsuccessful group. Visual tests included visual memory, visual reaction time, peripheral vision, recognition speed, saccadic eye movement, and facility of accommodation. The Successful group had better visual skills than the Unsuccessful group. Such visual skills enhance soccer referees' performance and may be recommended for young referees.     

Activation of cannabinoid CB1 receptors in the central amygdala impairs inhibitory avoidance memory consolidation via NMDA receptors

In the present study, we investigated the influence of bilateral intra-central amygdala (intra-CeA) microinjections of N-methyl-d-aspartate (NMDA) receptor agents on amnesia induced by a cannabinoid CB1 receptor agonist, arachydonilcyclopropylamide (ACPA). This study used a step-through inhibitory (passive) avoidance task to assess memory in adult male Wistar rats. The results showed that intra-CeA administration of ACPA (2 ng/rat) immediately after training decreased inhibitory avoidance (IA) memory consolidation as evidenced by a decrease in step-through latency on the test day, which was suggestive of drug-induced amnesia. Post-training intra-CeA microinjections of NMDA (0.0001, 0.001 and 0.01 μg/rat) did not affect IA memory consolidation. However co-administration of NMDA with ACPA (2 ng/rat) prevented the impairment of IA memory consolidation that was induced by ACPA. Although post-training intra-CeA administration of the NMDA receptor antagonist, d-(−)-2-amino-5-phosphonopentanoic acid (d-AP5; 0.01, 0.05 and 0.1 μg/rat) alone had no effect, its co-administration with an ineffective dose of ACPA (1 ng/rat) impaired IA memory consolidation. Post-training intra-CeA microinjection of an ineffective dose of d-AP5 (0.01 μg/rat) prevented an NMDA response to the impaired effect of ACPA. These results suggest that amnesia induced by intra-CeA administration of ACPA is at least partly mediated through an NMDA receptor mechanism in the Ce-A.     

Genistein ameliorates learning and memory deficits in amyloid β(1-40) rat model of Alzheimer's disease

Alzheimer's disease (AD) is a debilitating neurodegenerative disorder characterized by increased β-amyloid (Aβ) deposition and neuronal dysfunction leading to impaired learning and recall. Ageing, heredity, and induced oxidative stress are among proposed risk factors. The increased frequency of the disease in women also suggests a role for estrogen in development of AD. In the present study, effects of the phytoestrogen genistein (10mg/kg) on learning and memory impairments was assessed in intrahippocampal Aβ(1-40)-injected rats. The estrogen receptor antagonist fulvestrant was injected intracerebroventricularly in a group of Aβ-lesioned rats. The Aβ-injected animals exhibited the following: lower spontaneous alternation score in Y-maze tasks, impaired retention and recall capability in the passive avoidance test, and fewer correct choices and more errors in the RAM task. Genistein, but not genistein and fulvestrant, significantly improved most of these parameters. Measurements of oxidative stress markers in hippocampal tissue of Aβ-injected rats showed an elevation of malondialdehyde (MDA) and nitrite content, and a reduction of superoxide dismutase (SOD) activity. Genistein significantly attenuated the increased MDA content but did not affect the nitrite content or SOD activity. These results indicate that genistein pretreatment ameliorates Aβ-induced impairment of short-term spatial memory in rats through an estrogenic pathway and by inducing attenuation of oxidative stress.     

Seeing green: Mere exposure to money triggers a business decision frame and unethical outcomes

Can mere exposure to money corrupt? In four studies, we examined the likelihood of unethical outcomes when the construct of money was activated through the use of priming techniques. The results of Study 1 demonstrated that individuals primed with money were more likely to demonstrate unethical intentions than those in the control group. In Study 2, we showed that participants primed with money were more likely to adopt a business decision frame. In Studies 3 and 4, we found that money cues triggered a business decision frame, which led to a greater likelihood of unethical intentions and behavior. Together, the results of these studies demonstrate that mere exposure to money can trigger unethical intentions and behavior and that decision frame mediates this effect.
