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.

Impacts of moving frequently

When I post a long blog, I try to follow it with a shorter one. This article is also the only one I have found on the topic. Given fragile economic times for many people, we can expect more children moving as homes are foreclosed, apartment owners change, and families can’t make rent and mortgage payments. Abenavoli, Amadon & Briggs (2025) published “Cascading Effects of Residential Mobility on Maternal and Child Mental Health” in Developmental Psychology. Here are the edited abstract and impact statement:

Poverty effects

I recently found two articles dealing with effects of poverty on children. First, Cooper, Bayly, Tennie, Lupini & Wadsworth (2025) published “Family Risk Classes Predict Longitudinal Parent and Child Outcomes: Understanding the implications of poverty-related adversity” in Journal of Family Psychology. Here are highly edited excerpts:

Experiencing poverty and associated risk factors can be detrimental to families’ mental health and well-being. However, it is unclear whether experiencing specific types or patterns of adversity leads to distinct outcomes.

Emotion regulation in daily life

Both of the articles today come from Emotion and each deals with emotion regulation. First,  Ho, Joormann, Kober & Gadassi-Polack (2025) published “Social Reorientation of Emotion Regulation: Changing roles of family and peers during adolescence” in Emotion. The edited abstract follows:

The emotional climate of the family and peer group is theorized to play a central role in the development of emotion regulation (ER) in children and adolescents, such that warmer, more supportive environments promote more effective ER.

Cold executive functions and externalizing behavior

As a reminder, hot executive functions deal with emotion, motivation, and reward while cold executive functions deal more with attention and other cognitive functions. Choy (2025) published “Cold Executive Functions Moderate the Relationship between Hot Executive Function and Externalizing Behavior in Adolescents and Adults” in Neuropsychology. Here are the edited abstract and impact statement:

Psychosis and schizophrenia

I recently found several articles dealing with psychopathology. First, Bronstein et al. (2025) published “Delineating Empirically Plausible Causal Pathways to Suicidality among People at Clinical High Risk for Psychosis” in Journal of Psychopathology and Clinical Science. Here are the edited abstract and impact statements:

Suicidality is common among people at clinical high risk (CHR) for psychosis. Delineating causal pathways to suicidality and identifying its determinants would inform tailored intervention efforts for these individuals.

Studies of suicide

Today, we’re looking at three very different articles pertaining to suicide. First, Schafer, Wilson-Lemoine & Joiner (2024) published “Loneliness in Veterans: A commonality across multiple pathways toward suicidality” in Traumatology.  Here’s the edited abstract:

Veterans are significantly more likely to experience suicidality than the general population. A substantial amount of research has centered on risk factors of suicidality among veterans, identifying associations between Military-relevant risk factors including traumatic brain injuries (TBIs) and combat exposure with suicidality.

Self-compassion

The three studies we examine today all reflect work to enhance self-compassion. First, Yuan, Chang, Jiang & Jiang (2025) published “Be Kinder to Yourself: Awe promotes self-compassion via self-transcendence” in Emotion. Here’s the edited abstract:

Deficits in self-compassion heighten the vulnerability of mental disorders and jeopardize well-being, emphasizing the necessity of fostering self-compassion during unexpected suffering. In this research, we investigate awe as an antecedent for promptly promoting self-compassion.

Studies of narcissism

It’s been a while since I posted anything about narcissism. The three studies we examine today may be helpful. First, Rogoza, Baran, Flakus, Krammer & Fatfouta (2024) published “Introducing the Narcissistic Antagonism Scale: A missing puzzle piece in the assessment of momentary narcissism” in Psychological Assessment. Here’s the edited abstract:

Narcissism is a relatively stable personality trait, which is most accurately described by three facets: agentic, antagonistic, and neurotic. Existing studies support the central role of antagonistic narcissism and its role in explaining the process of fluctuation in narcissism.

Opioid use

We’re looking at three very different studies of opioid use. First, Snyder, Hartinger-Saunders, Yoon, Scott, Jr. & DiGirolamo (2025) published “Childhood Maltreatment and Adult Opioid Use: A systematic review of the literature” in Traumatology. Here’s the edited abstract:

This review fills an important gap in the literature by identifying studies linking childhood maltreatment to adult opioid misuse, assessing methodological rigor including study measures and analyses, and reviewing substantive findings to identify common relationships across studies.

Attitudes Toward Migrants 

Today, we’re looking at two articles that look at migrants. First, Santhanagopalan, Hok, Shaw & Kinzler (2024) published “The Ontogeny of Attitudes Toward Migrants“ in Developmental Science. Here are some excerpts:

Immigration is among the most pressing issues of our time. Important questions concern the psychological mechanisms that contribute to attitudes about immigration. Whereas much is known about adults’ immigration attitudes, the developmental antecedents of these attitudes are not well understood.

Studies of media use

Today, we’re looking at five articles addressing very different aspects of media use. First, we look at 3-6 year olds. Pecukonis, Yücel, Lee, Knox, Boas & Tager-Flusberg (2025) published “Do Children's Brains Function Differently During Book Reading and Screen Time? A fNIRS Study” in Developmental Science. Here’s the edited abstract:

Previous research suggests that book reading and screen time have contrasting effects on language and brain development. However, few studies have explicitly investigated whether children's brains function differently during these two activities.

Committing to emotion regulation

Today, we‘re reviewing four articles related to emotion regulation. First, Luo, McRae & Waugh (2024) published “Committing to Emotion Regulation: Factors impacting the choice to implement a reappraisal after its generation” in Emotion. Here’s the edited abstract:

Cognitive reappraisal, changing the way one thinks about an emotional event, is one of the most effective and extensively studied emotion regulation strategies.

Studies of mathematical skills

As we learn more about the decline in math skills, it seems worth it to examine recent research. First, Amland, Grande, Scherer, Lervåg & Melby-Lervåg (2024) published “Cognitive Factors Underlying Mathematical Skills: A systematic review and meta-analysis” in Psychological Bulletin. Here are the edited abstract and public significance statement:

In understanding the nature of mathematical skills, the most influential theories suggest that mathematical cognition draws on different systems: numerical, linguistic, spatial, and general cognitive skills. Studies show that skills in these areas are highly predictive of outcomes in mathematics.

Studies of suicide

The three studies I examine today all deal with suicide, using very different samples. First, Schafer, Wilson-Lemoine & Joiner (2024) published “Loneliness in Veterans: A commonality across multiple pathways toward suicidality” in Traumatology. Here’s the edited abstract:

Veterans are significantly more likely to experience suicidality than the general population. A substantial amount of research has centered on risk factors of suicidality among veterans, identifying associations between Military-relevant risk factors including traumatic brain injuries (TBIs) and combat exposure with suicidality. Likewise, loneliness has been shown to be a strong correlate of suicidality. Among these constructs, loneliness is proposed by multiple recent theories of suicide to contribute to the development of suicidality.

Studies of mindfulness

Today, we’re looking at three studies of mindfulness, each focusing on a different sample. First, Garber et al. (2024) published “A Randomized Controlled Trial of an Online Mindfulness Program for Adolescents at Risk for Internalizing Problems” in Journal of Consulting and Clinical Psychology. Here are the edited abstract and impact statement:

The purpose of this randomized controlled trial was to test the effects of an online, coached mindfulness intervention on momentary negative affect (mNA) for youth with high levels of trait negative affectivity.

Attachment in adulthood

Last time, we saw the role of parent-child attachment relationships. This time, we’re looking at adults. First, Dugan et al. (2024) published “Genetic and Environmental Contributions to Adult Attachment Styles: Evidence from the Minnesota Twin Registry” in Journal of Personality and Social Psychology. Here’s the edited abstract:

Attachment theory, as originally outlined by Bowlby, suggests that the ways people think, feel, and behave in close relationships are shaped by the dynamic interplay between their genes and their social environment

Attachment in children and teens

This and the next blog are going to address attachment. First, Dagan et al. (2023) published “Configurations of Mother-Child and Father-Child Attachment Relationships as Predictors of Child Language Competence: An individual participant data meta-analysis” in Child Development. Here’s the edited abstract:

An individual participant data meta-analysis was conducted to test pre-registered hypotheses about how the configuration of attachment relationships to mothers and fathers predicts children's language competence.

Mindset research

Those of you who’ve been reading the blog for a while, you know I like Carol Dweck’s research in general. This group of articles has two in which she’s a coauthor. Chen et al. (2025). A Strategic Mindset Enhances Children’s Generation of Effective Strategies and Delay of Gratification across Tasks” in Developmental Psychology. Here are some excerpts:

Overcoming challenges to achieve success involves being able to spontaneously come up with effective strategies to address different task demands. Research has linked individual differences in such strategy generation and use to optimal development over time and greater success across many areas of life. Yet, there is surprisingly little experimental evidence that tests how we might help young children to spontaneously generate and apply effective strategies across different challenging tasks. We test this in an area important to development: delaying gratification.

Dyslexia studies

Today, I’m looking at two studies pertaining to dyslexia, each available in full text. First, McDonough (2023) “Research on dyslexia is identifying the many factors — neural to societal — that are linked to the condition” in Harvard Gazette. Here are some excerpts.

As a child, Roberto Olivardia didn’t enjoy reading. Processing the words on a page fatigued him. But Olivardia — now a psychologist at McLean Hospital and a lecturer at Harvard Medical School — never considered that he might have dyslexia.
