The Blog

One of the many pleasures of being a professor was feeling the need to stay on top of the research in psychology. When I first learned about the half-life of knowledge, the literature typically said it was 3-5 years in technical fields. As a retired professor, I am still a member of the American Psychological Association and subscribe to a service that delivers abstracts and open-source articles from a large number of journals. As an alumna of Harvard, I also get information from them and I have the time to peruse multiple sources. This is a pleasure most professionals don’t have, especially if they value
work-life balance.

I still love research and, when I was asked to write the blog, I enthusiastically agreed. I try to select articles based on their relevance to practitioners, but also to capture both emerging themes and important corrections. I am hopeful that, moving forward, we will have ways to enable readers to easily engage in conversations with me and each other.

What makes humans smart?

Since the last post was long, this is a fun short one. Shaw (2023) published “What Makes Humans Smart?” in Harvard Magazine emphasizing the work of Joseph Henrich, a professor of biological anthropology. I love this updated look at sociobiology and think it has important implications for mental health professionals. Here’s the edited article:

Continuity in hostile family relationships

Today, we are examining hostile family relationships. Lee, Wickrama & O'Neal (2023) published “Continuity in Hostile Family Relationships Mediated by Family Psychopathology: An application of systems perspective” in Journal of Family Psychology. Here is the highly edited article:

Grounded in the family systems theory within the life course systems perspective, this study sought to investigate (a) long-term transmission processes of hostility from interparental relationships to parent–young adult relationships and (b) the mediational roles of parents’ and adolescents’ psychopathology in these long-term processes

Working memory performance is related to childhood trauma but not psychotic-like experiences in a nonpsychiatric sample

Ered, Chun, O'Brien, Creatura & Ellman (2023) published “Working Memory Performance is Related to Childhood Trauma but not Psychotic-Like Experiences in a Nonpsychiatric Sample” in Psychological Trauma: Theory, Research, Practice, and Policy. Here’s the edited abstract and impact statement:

This project seeks to clarify the impact of childhood trauma and psychotic-like experiences (PLEs) on working memory (WM) and explore gender differences in these relationships. The effect of childhood trauma on WM performance has yet to be explored in individuals with PLEs, despite consistent associations between trauma, psychosis spectrum symptoms, and WM performance. In 466 undergraduates, positive PLEs (Prodromal Questionnaire) and trauma (Childhood Trauma Questionnaire) were examined to determine contributions to WM performance on a spatial n-back task.

Effects of English versus Spanish language exposure on basic multisensory attention skills across 3 to 36 months of age

While the cognitive benefits of bilingual experience had been well established, there are still people who disparage non-native English speakers as if English is a superior language. Edgar, Todd, Eschman, Hayes & Bahrick (2023) published “Effects of English versus Spanish Language Exposure on Basic Multisensory Attention Skills across 3 to 36 Months of Age” in Developmental Psychology.

Three studies of AMPD

The DSM-5 Alternative Model for Personality Disorders (AMPD) has been around since 2015 although related research goes back to 2003. The DSM-V identifies Criterion A: impairments or deficits in sense of self and interpersonal relatedness; and Criterion B: five domains of negative affectivity, detachment, psychoticism, antagonism, and disinhibition. Today, I want to address three recent studies utilizing it. First, Yalch, Hujing & Hopwood (2023) published “Association Between Maladaptive Personality Traits and Violence Risk” in Journal of Threat Assessment and Management.  Here’s the edited abstract and impact statement:

Effects of vicarious processing

Today, I address two studies that focus on vicarious experiences. First, ElTohamy, et al. (2023) published “Effect of Vicarious Discrimination on Race-Based Stress Symptoms among Asian American Young Adults during the COVID-19 Pandemic.” Psychological Trauma: Theory, Research, Practice, and Policy. Here’s the edited abstract and impact statement:

The COVID-19 pandemic has led to a rise in anti-Asian hate crimes in the United States. Previous work has established that experiencing racism increases one’s dysfunctional anxiety and avoidance actions—key symptoms of race-based stress symptoms.

Autism and shame

I am providing a lengthy article because I think it offers important insights regarding people on the autism spectrum. Van Trigt, Colonnesi, Brummelman, Jorgenson & Nicolic (2023) published “Autistic Traits and Self-Conscious Emotions in Early Childhood” in Child Development. Here’s the highly edited article:

Self-conscious emotions arise from evaluating the self through the eyes of others. Given that children with autistic traits may experience difficulties with understanding others' minds, they might show less attuned self-conscious emotions. Self-conscious emotions reflect the interpersonal self, that is, how the self relates to others. Some self-conscious emotions, such as guilt and embarrassment after misbehavior motivate prosocial behaviors and evoke forgiveness and appeasement in others. Other self-conscious emotions, such as shame, are considered less socially adaptive, as they trigger withdrawal and avoidance, thereby inhibiting prosocial behaviors. A lack or surplus of self-conscious emotions could lead to problems in forming and maintaining social relationships, since self-conscious emotions help people navigate social situations in which they misbehaved or broke social rules. Given the difficulties in navigating social relationships, children with more autistic traits might be prone to disturbances in self-conscious emotions after transgression.

Effects of war exposure

A substantial portion of U.S. combat veterans reported having enjoyed violence during war. Our findings point to the importance of being open to the possibility that appetitive aggression is not uncommon in U.S. combat veterans and to the need to be prepared to face this sequela of combat with the same compassion, openness, and understanding we currently offer when encountering other wounds of war.
