Cautionary Notes: The Science of Trigger Warnings

What is the logic behind using trigger warnings? Do they improve learning outcomes?

 

In this episode, Under the Cortex hosts Victoria Bridgland of Flinders University to explore her meta-analysis results on trigger warnings. Bridgland’s meta-analysis indicates that, contrary to popular belief, trigger warnings do not have a negative or positive effect on learning outcomes but do increase anticipatory anxiety.

 

The conversation with APS’s Özge G. Fischer-Baum evolves into implications for cultural differences and the usage of trigger warnings on social media.

Feeling Young at Heart Comes With Well-Being Benefits

Is it true that you are only as old as you feel? Is age really just a number? Is 40 the new 30? 

 

In this episode, Under the Cortex hosts Markus Wettstein of Humboldt University of Berlin. Wettstein’s research explores the perception of subjective age in adulthood and gender, as well as generational differences in feeling young. 

The conversation with APS’s Özge G. Fischer-Baum evolves into implications for health benefits, general well-being, and possible cross-cultural differences. Wettstein also published on this topic in APS’s flagship journal, Psychological Science. The article is titled Younger Than Ever? Subjective Age is Becoming Younger and Remains More Stable in Middle-Age and Older Adults Today. 

The Tale of Two Cities: Water Access Influences Human Decision Making

Does our geographical location shape our thinking? Does water access have an effect on our decision-making habits? Do we choose to live in the moment because of environmental factors? 

In this episode, Under the Cortex hosts Dr. Hamid Harati, The University of Queensland, and Thomas Talhelm,University of Chicago. Through their international collaboration, the two scholars explore how our ecological environment can shape our decision-making skills. As they compare two cities in Iran, Yazd and Shiraz, they ask how cultures form based on environmental needs and how water scarcity can be a strong influencer of long-term orientation in basic life decisions. The conversation with APS’s Özge G. Fischer-Baum evolves into implications for climate change and the value of water as a monetary object. 

Harati and Talhelm also published on this topic in APS’s flagship journal, Psychological Science. Their article is titled Cultures in Water-Scarce Environments Are More Long-Term Oriented. The authors encourage scholars from across the globe to reach out to further explore these questions in future collaborations.

Loneliness Across the Globe: A Life-Span Approach

Did you know that loneliness is different from social isolation? Psychologists define loneliness as a subjective concept which is related to one’s own expectations.  

In this episode, Under the Cortex hosts Samia Akther Khan, PhD candidate from King’s College London, whose research examines the feeling of loneliness across lifespan. The conversation with APS’s Özge G. Fischer-Baum focuses on the difference between loneliness and social isolation and highlights six key social relationship expectations of older adults: (1) availability of social contacts, (2) receiving care and support, (3) intimacy and understanding, (4) enjoyment and shared interests, (5) generativity and contribution, and (6) being respected and valued. Along with other implications, Samia discusses the importance of global research and specific challenges that global research teams face. 

Samia Akhtar Khan also published on this topic in APS’s Perspectives with co-authors Matthew Prina, Gloria Hoi-Yan Wong, Rosie Mayston, and Leon Li. The article is titled, Understanding and Addressing Older Adults’ Loneliness: The Social Relationship Expectations Framework. 

 

 

Wendy Wood: It’s Time We Trained Students for Diverse Careers in Psychological Science

Psychology PhDs have skills broadly relevant for teaching, industry, and government. They are integral to producing basic research and evidence-based solutions for policy and industry. Only about half of psychology PhDs are hired in academia, but psychology graduate training in the United States has largely retained the classic graduate training model of a direct path to an academic job. It's time to change that, says APS President Wendy Wood. 

Best Of: Revisiting Episodes on the Myers-Briggs Test, the Grieving Brain, and More

At the height of the COVID-19 epidemic in 2020, the Association for Psychological Science joined countless other organizations around the world in turning to podcasts to share findings and conversations. The result is Under the Cortex, which now celebrates 100 episodes in which psychological scientists help us understand some of their most interesting and impactful new research. This special episode is a bit of a greatest hits compilation, featuring clips from six of our favorite episodes to date.

• Dan McAdams provides a skeptical deep dive on the Myers Briggs test. 
• Mary Frances O'Connor discusses what happens in the grieving brain.
• APS's Charles Blue and Ludmila Nunes debunk some common myths of psychological science. 
• Nathan Cheek explores some of the unintended negative consequences of restricting freedoms.

Understanding Childhood Adversity Across Time and Cultures

Scientists usually expect childhood to be nurturing, safe, and characterized by high levels of caregiver investment. However, evidence from history, anthropology, and primatology can challenge this view. Throughout human evolution, children have faced threats and deprivation, at varied levels across space and time. And these varied levels of exposure to adversity—which over time were higher than is typical in industrialized societies—likely favored a high degree of phenotypic plasticity, or the ability to tailor development to different conditions. 

Willem Frankenhuis, an evolutionary and developmental psychologist at Utrecht University, and Dorsa Amir, a developmental scientist at the University of California, Berkeley, have published research synthesizing evidence from history, anthropology, and primatology relevant to estimating childhood adversity across human evolution. These cross-cultural investigations have focused on three forms of threat (infanticide, violent conflict, and predation) and three forms of deprivation (social, cognitive, and nutritional). Willem and Dorsa discuss their findings, along with some implications, in this conversation with APS’s Ludmila Nunes. They have also published on this topic, and Willem also recently presented some of their findings at the 2023 APS Annual Convention in Washington D.C. 

 

“What are the types of conditions that our ancestors experienced?” Dorsa asks. “And what does that perspective offer to us today in trying to better understand adversity?” 

Nobody’s Fool: How to Avoid Getting Taken In

How can our habits of thinking make us vulnerable to deception? What characteristics of information make it more likely to manipulate us? And how can we spot deception before it’s too late?

In this episode of Under the Cortex, Daniel Simons and Christopher Chabris join APS’s Ludmila Nunes to answer these questions and more, drawing from their brand new book: Nobody's Fool: Why We Get Taken In and What We Can Do About It. Daniel Simons is a cognitive scientist and professor of psychology at the University of Illinois, where he researches the limits of human awareness and memory. Christopher Chabris is a cognitive scientist who has taught at Union College and Harvard University. In 2010, they co-authored the best-selling book The Invisible Gorilla: How Our Intuitions Deceive Us, in which they wrote about cognitive illusions.  

Carl Hart on Clinicians’ Bias Toward Drug Use

 

Pervasive misconceptions about and bias against drug use in the United States have led to clinical norms that pathologize any use of certain kinds of drugs. This bias has harmful consequences. For instance, conflating substance use with substance disorder is used to justify curtailing certain people’s rights, which has broad consequences. Treating drug use as a brain disease reveals clinician bias. How can these misconceptions, and the actions they lead to, be corrected? And how can researchers and policymakers demystify drug use? 

 

This episode of Under the Cortex features Carl Hart, a neuroscientist at Columbia University who has studied the behavioral and neuropharmacological effects of psychoactive drugs in humans. His lab attempts to understand factors that mediate drug use, to develop effective treatments, and to translate that knowledge into more humane drug policies.  

 

In May, Carl spoke about some of his findings in a very popular presentation at the 2023 APS Annual Convention titled “Clinician Bias About Drug Use Contributes to Growing Restrictions on Liberty and Bodily Autonomy.” He explained how the inclination to think that any use of a certain drug, like cocaine or heroine, is pathological reveals a clinician bias. This conversation, with APS’s Ludmila Nunes, was recorded on-site at the convention shortly after Carl delivered his presentation.  

 

Bringing Contexts In, Taking Racism Out: How to Improve Cognitive Psychology

Cognitive psychology studies universal processes such as memory, decision making, or emotions, for example. However, the theoretical, epistemological, and methodological assumptions that support the field’s longtime focus on studying “cognitive universals” might have resulted in a science of human cognition based on the performance and behavior of people who are predominantly White, English-speaking, and socially dominant. In other words, scientific racism has likely influenced the study of cognition. How can researchers reshape cognitive psychology to become more aware of the roles of culture and context? 

Ayanna Thomas is a professor at Tufts University and lead author of an article published in Current Directions in Psychological Science that explores how psychological scientists can reshape the field of cognitive psychology and move toward well-developed theories of cognition in context. Ayanna joins APS’s Ludmila Nunes to discuss scientific racism in cognitive psychology.
