The update of semantic memories in amnestic mild cognitive impairment

It is still controversial to what extent neocortical consolidated memories are susceptible of change by processes of reconsolidation and transformation throughout experience, and whether the medial temporal lobes are necessary for this update of semantic consolidated memories, as they are for episodic remembering. We hypothesize that patients with amnestic mild cognitive impairment (aMCI) who have deficits in episodic memory may also have difficulties in updating information on added new features of objects. Sixteen participants with aMCI and 20 healthy control participants performed a semantic word-to-picture task, in which they were asked to identify as belonging to a given semantic category NEW objects, that have incorporated novel features, as well as OLD items, semantically and visually SIMILAR items and UNRELATED items. Patients with aMCI made a greater percentage of errors than healthy controls. Participants globally made greater percentages of errors in difficult types of items, namely NEW and SIMILAR, as compared to easier ones, OLD and UNRELATED. Importantly, an item by diagnostic group interaction effect was observed, and post hoc analysis showed that patients with aMCI made a higher percentage of errors than controls in NEW items only. In conclusion, patients with aMCI had a particular difficulty in identifying the NEW items of the word-to-picture task as compared to the control participants, supporting the concept of a flexible and dynamic conceptual knowledge system, involving the update of semantic memories and the integration of new attributes in a constant transformation process, which is impaired in these patients.

Bystander responses to bias-based bullying and retaliation: Is retaliation perceived as more acceptable than bias-based bullying?

The current study examined intergroup-related and social-cognitive correlates of bystanders' acceptability judgements and their responses to bias-based bullying of immigrant peers and to possible retaliation for the bullying. Participants included 179 immigrant-origin and non-immigrant-origin youth (M_age = 13.23; SD = 1.55; 79 immigrant-origin youth). Participants' bystander judgements and responses to bullying and retaliation were examined via a hypothetical scenario. Further, participants' intergroup attitudes towards immigrants and their social-cognitive skills were evaluated. ANOVA results showed that immigrant-origin youth judged bullying as less acceptable and retaliation as more acceptable compared to non-immigrant-origin youth, documenting that group membership is related to adolescents' judgements. A similar pattern was observed in active bystander responses. Hierarchical regression analyses revealed that immigration background, intergroup process in the context of immigration, and social-cognitive skills predict bystander responses to bullying and retaliation. This study provides important implications for anti-bullying intervention programmes to overcome the negative consequences of retaliation in the escalation of aggressive behaviours.     

“I knew that I wasn’t cis,I knew that,but I didn’t know exactly”: Gender identity development,expression and affirmation in youth who access gender affirming medical care

Abstract

Background: Research about gender identity development is still in its infancy, especially among youth who experience gender dysphoria and are accessing gender-affirming medical care.

Aims: This article contributes to the literature on how gender identity and gender dysphoria is experienced, expressed and addressed by youth who have started, or are just about to start, a gender-affirming medical intervention.

Methods: The project draws from qualitative interviews with 36 trans children and youth of different ages and stages of puberty. The data were collected in three specialized Canadian clinics that offer gender-affirming care and they were analyzed through inductive thematic analysis.

Results: Two interlinked dimensions of the youth’s lives allow meaning-making of their gender identity: 1) internal or personal and 2) interactional or social processes. Careful analysis reveals three gender identity development pathways that may be taken by youth, from early questioning to the affirmation of their gender identity. A discussion of current models of gender identity development and their limitations concludes the article.     

Priming effects of arithmetic signs in 10- to 15-year-old children

In this research, 10- to 12- and 13- to 15-year-old children were presented with very simple addition and multiplication problems involving operands from 1 to 4. Critically, the arithmetic sign was presented before the operands in half of the trials, whereas it was presented at the same time as the operands in the other half. Our results indicate that presenting the ‘x’ sign before the operands of a multiplication problem does not speed up the solving process, irrespective of the age of children. In contrast, presenting the ‘+’ sign before the operands of an addition problem facilitates the solving process, but only in 13 to 15-year-old children. Such priming effects of the arithmetic sign have been previously interpreted as the result of a pre-activation of an automated counting procedure, which can be applied as soon as the operands are presented. Therefore, our results echo previous conclusions of the literature that simple additions but not multiplications can be solved by fast counting procedures. More importantly, we show here that these procedures are possibly convoked automatically by children after the age of 13 years. At a more theoretical level, our results do not support the theory that simple additions are solved through retrieval of the answers from long-term memory by experts. Rather, the development of expertise for mental addition would consist in an acceleration of procedures until automatization.

Opposition to Immigration and (Anti-)Environmentalism: An Application and Extension of the Social Dominance-Environmentalism Nexus with 21 Countries in Europe

The social dominance–environmentalism nexus proposes that orientations for inequality and domination are expressed both in human–human and human–nature relations. In two studies, the present work applies and extends this proposition to understand endorsement of environmental values, concern with climate change, support for climate policies, and responsibility for climate action. In study one, using a representative random sample from Portugal (N = 1270, 53.3% female; European Social Survey, ESS8), social dominance orientation showed unique associations with concern with climate change. Moreover, opposition to immigration (as expression of anti-egalitarianism in intergroup relations) showed unique associations with all four measures of environmentalism. In study two, multi-level analyses using representative random samples from 20 other countries in Europe (N = 38830, 51.5% female; ESS8) confirmed the associations between opposition to immigration and environmentalism, controlling for a set of sociodemographic covariates, political orientation, and nesting at the country level. However, there were differences in the strength and direction of these associations based on country levels of societal development (i.e., Human Development Index; HDI). These differences reinforce the notion that context or situational variables may shape the links between diverse expressions of (anti-)egalitarianism and (anti-)environmentalism. Inputs for applied research on hierarchy-affirming tendencies toward others and the natural environment are proposed and discussed.
