Load release balance test under unstable conditions effectively discriminates between physically active and sedentary young adults

This study investigates test-retest reliability and diagnostic accuracy of the load release balance test under four varied conditions. Young, early and late middle-aged physically active and sedentary subjects performed the test over 2 testing sessions spaced 1 week apart while standing on either (1) a stable or (2) an unstable surface with (3) eyes open (EO) and (4) eyes closed (EC), respectively. Results identified that test-retest reliability of parameters of the load release balance test was good to excellent, with high values of ICC (0.78–0.92) and low SEM (7.1%–10.7%). The peak and the time to peak posterior center of pressure (CoP) displacement were significantly lower in physically active as compared to sedentary young adults (21.6% and 21.0%) and early middle-aged adults (22.0% and 20.9%) while standing on a foam surface with EO, and in late middle-aged adults on both unstable (25.6% and 24.5%) and stable support surfaces with EO (20.4% and 20.0%). The area under the ROC curve >0.80 for these variables indicates good discriminatory accuracy. Thus, these variables of the load release balance test measured under unstable conditions have the ability to differentiate between groups of physically active and sedentary adults as early as from 19 years of age.     

风险回避行为中的“红色图形效应”

以往研究发现,风险回避领域存在着一种经典的"图形效应"(即图形会比数字激发出个体更强的风险回避行为)。但以往研究通常只采用灰色或黑色来呈现风险信息。基于近来关于红色效应的探讨,本研究试图将颜色因素引入到图形效应中以探讨不同颜色下的图形效应特点。结果发现,相比于蓝色,红色能激发出个体更强的风险回避行为,且颜色对图形效应具有调节作用,即与蓝色相比,红色条件下出现了增强的图形效应,即"红色图形效应"。有关结果说明,红色作为一种危险警示颜色可以激发出个体更强的风险回避行为,且会诱发更大的图形效应。     

Countering Deficits: A Grounded Theory of Success From Graduate Students of Color

The existing research on students of color in counselor education focuses on the barriers they experience, providing a deficit perspective. Using grounded theory and a critical race theory framework, we studied the racialized experiences of 19 graduate students of color in counselor education. Grounded in participants' voices, we propose a liberatory theory of academic success. Implications for promoting the success of students of color in counselor education and for future critical race theory research are discussed. Las investigaciones hasta la fecha sobre estudiantes de color en programas educativos de consejería se centran en las barreras que afrontan, lo cual ofrece un déficit de perspectiva. Usando un muestreo teórico y un marco de teoría crítica de la raza, estudiamos las experiencias racializadas de 19 estudiantes de posgrado de color en programas educativos de consejería. Basándonos en las voces de los participantes, proponemos una teoría liberatoria de éxito académico. Se discuten las implicaciones para fomentar el éxito de estudiantes de color en programas educativos de consejería y para investigaciones futuras de teoría crítica de la raza.     

When Being “Essential” Illuminates Disparities: Counseling Clients Affected by COVID‐19

The 2019 novel coronavirus (COVID‐19) has highlighted social disparities in the United States. This article examines how preexisting racial and ethnic disparities, exacerbated by COVID‐19, have negatively affected communities of color that tend to be overrepresented in lower socioeconomic groups, have limited access to health care and education, have an undocumented status, and work in jobs considered “essential.” Counselors are encouraged to use creative strategies to design and facilitate telecounseling and reduced‐ or no‐cost workshops in which attendees can participate safely. Specific cultural considerations, aspects of crisis management, and creative interventions that can be used with clients of color at an appropriate social distance are discussed. Counselors can also instill hope in their clients by promoting sociopolitical development. As the impact of COVID‐19 will be felt for years, it is crucial that counselors be prepared to address the needs of those disproportionately affected.     

Intergroup threat,social dominance,and the malleability of ideology: The importance of conceptual replication

Consistent with the theory of malleable ideology, research has shown that, under intergroup threat, antiegalitarian individuals will exploit the malleable character of color blindness and strategically claim to be strong supporters of it. In three studies conducted in France, we found no support for this theory when measuring color blindness but strong support when using measures of laïcité, an ideology of secularism. Indeed, those who score low on social dominance orientation (SDO) were more likely to support laïcité than antiegalitarian individuals. However, a situational threat (Study 1), a symbolic threat experimentally induced (Study 2), and a perceived symbolic threat (Study 3) were all related to increased support for laïcité by people high in SDO, without affecting those low in SDO. Thus, laïcité is a malleable ideology that can be adopted by individuals having contrasting motivations, as color blindness in the United States. Implications for the role of exact and conceptual replications in the development of a psychological science are discussed.     

What matters is the underlying experience: Similar motor responses during processing observed hand actions and hand-related verbs

It is well-accepted that processing observed actions involves at some extent the same neural mechanisms responsible for action execution. More recently, it has been forwarded that also the processing of verbs expressing a specific motor content is subserved by the neural mechanisms allowing individuals to perform the content expressed by that linguistic material. This view is also known as embodiment and contrasts with a more classical approach to language processing that considers it as amodal. In the present study, we used a go/no-go paradigm, in which participants were requested to respond to real words and pictures and refrain from responding when presented stimuli were pseudowords and scrambled images. Real stimuli included pictures depicting hand- and foot-related actions and verbs expressing hand- and foot-related actions. We, therefore, directly compared the modulation of hand motor responses during the observation of actions and the presentation of verbs, expressing actions in the same category. The results have shown that participants gave slower hand motor responses during the observation of hand actions and the processing of hand-related verbs as than observed foot actions and related verbs. These findings support embodiment showing that whatever the modality of presentation (observed action or verb), the modulation of hand motor responses was similar, thus suggesting that processing seen actions and related verbs shares common mechanisms most likely involving the motor system and the underlying motor experience.     

I Am So Happy ‘Cause My Friend Is Happy for Me: Capitalization,Friendship, and Happiness Among U.S. and Turkish College Students

ABSTRACT

Friends usually share positive events in their lives with each other. Referred to as capitalization, this process promotes individual happiness when the discloser perceives that the responses display genuine support. Yet, the specific mechanisms explaining why capitalization is associated with happiness are not known. The present study addresses this empirical issue by testing a mediational model positing that friendship quality would mediate the relationship between capitalization and happiness among U.S. and Turkish college students. Although the psychosocial well-being of the U.S. participants was significantly higher than Turkish participants, the proposed model was supported in both groups. This suggests that part of the reason capitalization is associated with happiness is because of friendship experiences. The authors also provide suggestions for future research.     

The interaction between surface color and color knowledge: behavioral and electrophysiological evidence

In this study, we used event-related potentials (ERPs) to evaluate the contribution of surface color and color knowledge information in object identification. We constructed two color-object verification tasks - a surface and a knowledge verification task - using high color diagnostic objects; both typical and atypical color versions of the same object were presented. Continuous electroencephalogram was recorded from 26 subjects. A cluster randomization procedure was used to explore the differences between typical and atypical color objects in each task. In the color knowledge task, we found two significant clusters that were consistent with the N350 and late positive complex (LPC) effects. Atypical color objects elicited more negative ERPs compared to typical color objects. The color effect found in the N350 time window suggests that surface color is an important cue that facilitates the selection of a stored object representation from long-term memory. Moreover, the observed LPC effect suggests that surface color activates associated semantic knowledge about the object, including color knowledge representations. We did not find any significant differences between typical and atypical color objects in the surface color verification task, which indicates that there is little contribution of color knowledge to resolve the surface color verification. Our main results suggest that surface color is an important visual cue that triggers color knowledge, thereby facilitating object identification.     

Initial responses to the first dose of nicotine in novel smokers: The role of exposure to environmental smoking and genetic predisposition

Background: Sensitivity to initial smoking constitutes an early predictor of the risk of dependence. We investigated the role of exposure to smoking (by parents, siblings, and peers) and reward-related candidate gene polymorphisms (OPRM1 A118G, DRD2 TaqlA and DRD4?bp VNTR) in adolescents’ responses to initial smoking.

Methods: We used cross-sectional survey data and saliva samples from 171 Dutch students who had never inhaled on a cigarette (mean age: 13.9?years). The outcome measure was adolescents’ self-reported responses to initial smoking.

Results: Exposure to peer smoking was associated with increased liking (OR?=?1.74, CI?=?1.13–2.70) and more pleasant sensations (β?=?.21, p?=?.01). Exposure to maternal smoking was associated with less unpleasant sensations (β?=??.20, p?=?.01). Adolescents carrying the G-variant of the OPRM1 A118G polymorphism were more likely to report liking (OR?=?2.50, CI?=?1.09–5.73) and adolescents homozygous for the C-variant of the DRD2 TaqlA polymorphism reported less unpleasant sensations (β?=?.18, p?=?.04).

Conclusion: Although preliminary, these findings suggest that exposure to environmental smoking and polymorphisms in the OPRM1 and DRD2 gene may affect initial sensitivity to nicotine, an early phenotype of the risk of dependence. In the future, collaborative efforts to combine data from multiple studies in meta-analyses are needed to improve accuracy of estimated effects in genetic studies.
