Abstract: Self-affirmation theory posits that people are motivated to maintain a positive self-view and that threats to perceived self-competence are met with resistance. When threatened, self-affirmations can restore self-competence by allowing individuals to reflect on sources of self-worth, such as core values. Many questions exist, however, about the underlying mechanisms associated with self-affirmation. We examined the neural mechanisms of self-affirmation with a task developed for use in a functional magnetic resonance imaging environment. Results of a region of interest analysis demonstrated that participants who were affirmed (compared with unaffirmed participants) showed increased activity in key regions of the brain's self-processing (medial prefrontal cortex + posterior cingulate cortex) and valuation (ventral striatum + ventral medial prefrontal cortex) systems when reflecting on future-oriented core values (compared with everyday activities). Furthermore, this neural activity went on to predict changes in sedentary behavior consistent with successful affirmation in response to a separate physical activity intervention. These results highlight neural processes associated with successful self-affirmation, and further suggest that key pathways may be amplified in conjunction with prospection.

For centuries, Central America's Afro-Indigenous Garifuna people have kept the culture's oral history alive through their ancestors' native language. But decades of modernization, haphazard native-language training in Garifuna schools, intermarriage between cultures, and the ridicule of young people who speak the language, collectively led to Garifuna being listed on the UNESCO Atlas of Endangered Languages in 2001. Today, linguists estimate that about 100,000 speakers remain. The threat of language extinction isn't new. Some linguists estimate a language dies every two weeks, as some languages become dominant tools for social and economic exchange, while others are pushed to the margins. But there are ways to save at-risk languages, as well. The key is that the language needs to be thought of less as preserved, "but indeed part of their present and their future," says Liliana Sánchez, a linguist and professor at the University of Illinois at Chicago. That's exactly what the Garinagu (Garifuna people) are doing. For the past two decades, Garifuna artists have used a cultural cornerstone-spirited dance music-to inspire young Garinagu to learn and share their native language. Now, with a new Garifuna Tourism Trail project in Belize, travelers can experience and support the cultural renaissance, too. Elements of the Garifuna culture-including music, dance, and language-were listed as a UNESCO Masterpiece of Oral and Intangible Heritage of Humanity in 2001. Around that same time, Garifuna musicians and cultural activists hatched a plan: Create irresistible melodies, sung entirely in Garifuna, to rally young Garinagu to embrace the culture and learn the language. Will music save the Garifuna language? Time will tell. Garifuna remains on UNESCO's endangered-language list, last updated in 2010. And, as the Hawaiians learned from revitalizing their own language post colonization, this kind of revival is a long, multi-generational road.

Linguists are learning that climate change is another major factor contributing to the threat of language loss. This article dives into the effects of climate change on endangered languages such as Greenlandic and Marshallese, and explores how communities are taking action to protect their indigenous languages.

This book chapter discusses two research projects that examine how teachers/instructors view slang terms and how those views affect young people. It explains how young people have their own vernacular and how older generations who don't understand it may see "youth speak" as a threat to "standard" English.
