The Longitudinal Impact of a Family-Based Communication Intervention on Observational and Self-Reports of Sexual Communication

Parents can play a vital role in shaping teenagers’ sexual attitudes, behavior, and contraceptive use through communication, however, less is known about how to modify parent–adolescent communication among youth with mental health problems. The impact of a family-based sexual risk prevention intervention on both observational and self-report of parent–adolescent sexual communication was examined at 12 months among adolescents with mental health problems. Of the 721 parent–adolescent dyads recruited for the study, 167 videotapes of sexual discussions between parents and adolescent were coded for the family-based intervention and 191 videotapes for the active comparison. Longitudinal analyses examined differences between conditions (family-based vs. comparison) in self-reported and observed parent–adolescent sexual discussions and also examined the impact of gender on intervention response. More parent I-statements, healthier parent body language, and fewer adolescent Negative Vocalizations were detected for family-based intervention participants 12 months after participating in the brief intervention (11?h of total intervention time) relative to those in the comparison condition. Parents in the family-based intervention also self-reported better sexual communication at 12 months. The current study provides supporting evidence that a relatively brief family-based intervention was successful at addressing parent–adolescent sexual communication among a mental health sample.     

Effects of absolute luminance and luminance contrast on visual search in low mesopic environments

Diverse adaptive visual processing mechanisms allow us to complete visual search tasks in a wide visual photopic range (>0.6 cd/m²). Whether search strategies or mechanisms known from this range extend below, in the mesopic and scotopic luminance spectra (<0.6 cd/m²), has yet to be addressed. Based on a study that addressed simple target discrimination in luminance environments using contrast-dependent behavioral efficiency functions, we assessed visual search in more complex-feature and conjunction-search paradigms. The results verify the previously reported deficiency windows defined by an interaction of base luminance and luminance contrast for more complex visual-search tasks. Based on significant regression analyses, a more precise definition of the magnitude of contribution of different contrast parameters. Characterized feature search patterns had approximately a 2.5:1 ratio of contribution from the Michelson contrast property relative to Weber contrast, whereas the ratio was approximately 1:1 in a serial-search condition. The results implicate near-complete magnocellular isolation in a visual-search paradigm that has yet to be demonstrated. Our analyses provide a new method of characterizing visual search and the first insight in its underlying mechanisms in luminance environments in the low mesopic and scotopic spectra.

     

Vocation for planetary citizenship: Lutheran liberal arts education in the Anthropocene

The focus question of this article is, “In what ways should Lutheran higher education's teaching on vocation be revised to include the fact that we are living in a natural world massively impacted by human behavior, the Anthropocene Era?” This can be broken down into two more explicit questions: “What is the role of liberal arts education in such a changed context?” and “What resources in the Lutheran tradition can contribute to preparing students to become effective sustainability leaders?” The thesis of this article is that Lutheran liberal arts education, to foster planetary citizenship, must move students from an anthropocentric to an ecocentric understanding of vocation, preparing them to become leaders for a sustainable, interfaith society. This change can be accomplished by reaffirming the value of the liberal arts to foster sustainability education and retrieving Luther's understanding of creation to elicit wonder and appreciation of the natural world.     

A prospective investigation of rumination and executive control in predicting overgeneral autobiographical memory in adolescence

The CaR-FA-X model (Williams et al., 2007), or capture and rumination (CaR), functional avoidance (FA), and impaired executive control (X), is a model of overgeneral autobiographical memory (OGM). Two mechanisms of the model, rumination and executive control, were examined in isolation and in interaction in order to investigate OGM over time. Across two time points, six months apart, a total of 149 adolescents (13–16 years) completed the minimal-instruction autobiographical memory test, a measure of executive control with both emotional and nonemotional stimuli, and measures of brooding rumination and reflective pondering. The results showed that executive control for emotional information was negatively associated with OGM, but only when reflective pondering levels were high. Therefore, in the context of higher levels of reflective pondering, greater switch costs (i.e., lower executive control) when processing emotional information predicted a decrease in OGM over time.
