Exploring well-being among US Hispanics/Latinos in a church-based institution: a qualitative study

Major theories informing conceptions of psychological well-being draw heavily from Western-centric perspectives, which often neglect culturally bound frameworks. We investigated how US Hispanics/Latinos conceptualize well-being, how psychosocial and behavioral aspects may increase well-being, and how psychosocial stressors may impact positive emotional states. Spanish-speaking Hispanic/Latino adults were recruited from a church in an urban city in the US and invited to participate in focus groups. Two groups of women (n = 19) and one group of men (n = 8) participated. The importance of harmonious social relationships emerged as a theme with the central family unit as the fundamental force influencing long-lasting emotional well-being. Additional correlates of well-being included: faith/religiosity; physical health; self-love and -esteem; effective/open communication with family and friends; and financial security. Programs aimed at increasing well-being may need to be adapted before administration in Hispanics/Latinos to include a heightened focus on interpersonal factors. Delivery in religious institutions may also be particularly beneficial.     

Increased training complexity reduces the effectiveness of brief working memory training: evidence from short-term single and dual n-back training interventions

N-back training has recently come under intense scientific scrutiny due to reports of training-related improvements in general fluid intelligence. As of yet, relatively little is known about the effects of short-term n-back training interventions, however. In a pretest-training-posttest design, we compared brief dual and single n-back training regimen in terms of training gains and transfer effects relative to a passive control group. Transfer effects indicated that, in the short-term, single n-back training may be the more effective training task: At the short training duration we employed, neither training group showed far transfer to specific task switch costs, Stroop inhibition costs or matrix reasoning indexing fluid intelligence. Yet, both types of training resulted in a reduction of general task switch costs indicating improved cognitive control during the sustained maintenance of competing task sets. Single but not dual n-back training additionally yielded near transfer to an untrained working memory updating task.     

Cofinal Stable Logics

We generalize the \({(\wedge, \vee)}\)-canonical formulas to \({(\wedge, \vee)}\)-canonical rules, and prove that each intuitionistic multi-conclusion consequence relation is axiomatizable by \({(\wedge, \vee)}\)-canonical rules. This yields a convenient characterization of stable superintuitionistic logics. The \({(\wedge, \vee)}\)-canonical formulas are analogues of the \({(\wedge,\to)}\)-canonical formulas, which are the algebraic counterpart of Zakharyaschev’s canonical formulas for superintuitionistic logics (si-logics for short). Consequently, stable si-logics are analogues of subframe si-logics. We introduce cofinal stable intuitionistic multi-conclusion consequence relations and cofinal stable si-logics, thus answering the question of what the analogues of cofinal subframe logics should be. This is done by utilizing the \({(\wedge,\vee,\neg)}\)-reduct of Heyting algebras. We prove that every cofinal stable si-logic has the finite model property, and that there are continuum many cofinal stable si-logics that are not stable. We conclude with several examples showing the similarities and differences between the classes of stable, cofinal stable, subframe, and cofinal subframe si-logics.
