Selective attention to the color and direction of moving stimuli: Electrophysiological correlates of hierarchical feature selection

Event-related brain potentials (ERPs) were recorded from subjects who attended to pairs of adjacent colored squares that were flashed sequentially to produce a perception of movement. The task was to attend selectively to stimuli in one visual field and to detect slower moving targets that contained the critical value of the attended feature, be it color or movement direction. Attention to location was reflected by a modulation of the early P1 and N1 components of the ERP, whereas selection of the relevant stimulus feature was associated with later selection negativity components. ERP indices of feature selection were elicited only by stimuli at the attended location and had distinctive scalp distributions for features mediated by “ventral” (color) and “dorsal” (motion) cortical areas. ERP indices of target selection were also contingent on the prior selection of location but initially did not depend on the selection of the relevant feature. These ERP data reveal the timing of sequential, parallel, and contingent stages of visual processing and support early-selection theories of attention that stipulate attentional control over the initial processing of stimulus features.     

Racial and cultural in-betweenness meet in the consulting room: the case of ‘Anna’

An upper-middle-class black woman, who grew up adapting to a white-dominated environment, entered the consulting room of a multicultural ‘white-passing’ analyst, and here unique emotional experiences were reflected in dream images of racial disorganization, internal racism, and identity confusion. While sorting through the analysand’s internal dynamics, the external world erupted in May 2020 with the murder of George Floyd, catapulting both analysand and analyst (and the nation) into a transformative confrontation with their mutual, deep-seated woundings of American racial and cultural inequities. The analysand’s racial complexity directly impacted the analyst’s ‘white-passing’ privilege, bringing into question established classifications of American whiteness. Overlapping dynamics and experiences as ‘in-betweeners’ and ‘outsiders’ – a black woman subsumed by a white-dominated society and an immigrant refugee acculturated to American life – provided a common exilic ground for mutual understanding and mirroring. The analyst explores the racial and multicultural straddling that served as a lens into the analysand’s fragmented racial identity during the eruption of American racial unrest.     

Forgiveness,Depression, and Suicidal Behavior in Adolescents: Gender Differences in this Relationship

With the development of positive psychology, protective factors have received increased attention as buffers against suicidal ideation and attempts and against the risk factors for suicide (e.g., depressive symptoms). Empirical evidence suggests that one of the protective factors associated with depression and suicide is forgiveness. Although previous studies have demonstrated a negative association between forgiveness and risk of suicide, studies on gender differences in adolescents are still scarce. Thus, the authors assessed the moderating role of gender in a sample of adolescents. The participants were 572 adolescents (50.9% boys; M age = 15.49 years, SD = 1.09 years) from secondary school centers. The results revealed that forgiveness moderated the relationship between depression and suicidal ideation for boys but not for girls. Specifically, for boys the relationship between depression and suicidal thoughts and behaviors weakened as levels of forgiveness increased. These findings suggest therapeutic applications to reduce the likelihood of suicide in the group of adolescent boys with higher scores on depression and lower levels of forgiveness. The study results are discussed in terms of the need to use gender perspectives in positive psychology intervention programs.     

Experiencing the mastership in transdisciplinary studies for sustainability

In this article, we describe the transdisciplinarity process in our education postgraduate program at the University of Veracruz. The program emphasizes the main processes of the eco-formation experience for sustainability through a transdisciplinarity methodology that is focused on three processes: (a) Re-Learning; (b) Eco-literacy; and (c) Dialogue of Knowledge. The experience of self-knowledge is described through our specific re-learning practices in the Mastership program, which represents a central tenet in the process for creating our Learning Community through holarchy practices, profound dialogues, and self-organization processes. Finally we discuss three central ideas: creativity, spirituality, and play, which express and nurture our Learning Community.     

Longitudinal Effects of Latino Parent Cultural Stress,Depressive Symptoms,and Family Functioning on Youth Emotional Well‐Being and Health Risk Behaviors

U.S. Latino parents can face cultural stressors in the form of acculturative stress, perceived discrimination, and a negative context of reception. It stands to reason that these cultural stressors may negatively impact Latino youth's emotional well‐being and health risk behaviors by increasing parents' depressive symptoms and compromising the overall functioning of the family. To test this possibility, we analyzed data from a six‐wave longitudinal study with 302 recently immigrated (<5 years in the United States) Latino parents (74% mothers, M_age = 41.09 years) and their adolescent children (47% female, M_age = 14.51 years). Results of a cross‐lagged analysis indicated that parent cultural stress predicted greater parent depressive symptoms (and not vice versa). Both parent cultural stress and depressive symptoms, in turn, predicted lower parent‐reported family functioning, which mediated the links from parent cultural stress and depressive symptoms to youth alcohol and cigarette use. Parent cultural stress also predicted lower youth‐reported family functioning, which mediated the link from parent cultural stress to youth self‐esteem. Finally, mediation analyses indicated that parent cultural stress predicted youth alcohol use by a way of parent depressive symptoms and parent‐reported family functioning. Our findings point to parent depressive symptoms and family functioning as key mediators in the links from parent cultural stress to youth emotional well‐being and health risk behaviors. We discuss implications for research and preventive interventions.     

Determinantes familiares,escolares y grupales del consumo de drogas en la adolescencia. Implicaciones para el Tratamiento

Resumen

El propósito del presente artículo es el de llamar la atención acerca de la necesidad de recoger los datos que señalan la importancia de los grupos familiar, escolar y de iguales, de cara a la elaboration de programas concretos de prevención y tratamiento de incidencia en estos tres entornos del adolescente. Con este fin, en primer lugar se analizarán los principales hallazgos de las investigaciones que relacionan la familia, la escuela y el grupo de iguales con la aparición de drogodependencias en los adolescentes. Como segundo paso se apuntarán las líneas generales de aplicación de estos hallazgos en programas de prevención e intervención.     

Increasing ethnic minority participation in substance abuse clinical trials: lessons learned in the National Institute on Drug Abuse's Clinical Trials Network

Underrepresentation in clinical trials limits the extent to which ethnic minorities benefit from advances in substance abuse treatment. The objective of this article is to share the knowledge gained within the Clinical Trials Network (CTN) of the National Institute on Drug Abuse and other research on recruiting and retaining ethnic minorities into substance abuse clinical trials. The article includes a discussion of two broad areas for improving inclusion-community involvement and cultural adaptation. CTN case studies are included to illustrate three promising strategies for improving ethnic minority inclusion: respondent-driven sampling, community-based participatory research, and the cultural adaptation of the recruitment and retention procedures. The article concludes with two sections describing a number of methodological concerns in the current research base and our proposed research agenda for improving ethnic minority inclusion that builds on the CTN experience.     

Questionnaire of executive function for dancers: an ecological approach

There is a current debate about the ecological validity of executive function (EF) tests. Consistent with the verisimilitude approach, this research proposes the ballet executive scale (BES), a self-rating questionnaire that assimilates idiosyncratic executive behaviors of classical dance community. The BES was administrated to 149 adolescents, students of the Cuban Ballet School. Results present a Cronbach's alpha coefficient of .80 and a split-half Spearman-Brown coefficient r (SB) = .81. An exploratory factor analysis describes a bifactorial pattern of EF dimensions, with a self-regulation component, which explains more than 40% of variance, and a Developmental component, which accounts for more than 20% of variance. The questionnaire's total scores fit linear regression models with two external criteria of academic records, confirming concurrent validity. These findings support the hypothesis that the internalization of specific contextual cultural meanings has a mediating influence in the development of EF.
