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.

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. Here’s the edited abstract and impact statement:

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:

Teen victimization, rumination, adult depression, and aggression

This is a lengthy article but I find its content fascinating, especially in light of growing evidence of teen victimization, especially online. Malamut & Salmivalli (2023) published “Adolescent Victimization Predicts Adult Depression and Aggression: The role of rumination” in Developmental Psychology. Here’s the highly edited article:

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.

Anti-dopamine parenting

This post comes from a story originally on NPR’s Morning Edition. In late June 2023, Six Things Psychologists Are Talking About posted Miotke’s “Anti-dopamine parenting can curb a kid’s craving for screens or sweets.” Here’s the highly edited transcript with some bold in the tips section:

Back when my daughter was a toddler, I would make a joke about my phone: "It's a drug for her," I'd say to my husband. "You can't even show it to her without causing a tantrum." She had the same reaction to cupcakes and ice cream at birthday parties.

Rethinking intelligence

In a previous post, I discussed Ackerman’s (2023) “Intelligence . . . Moving Beyond the Lowest Common Denominator” published in American Psychologist. Here’s another response to his article. Sternberg (2023) published “Intelligence is not the ‘entire repertoire of knowledge’, but rather the repertoire of adaptive knowledge: Commentary on Ackerman (2023).” in American Psychologist. Here’s the edited abstract and article:
