How people decide to consume (more) alcohol when feeling stressed
The tension reduction hypothesis posits that people consume alcohol to alleviate stress and negative emotions. Prior experimental studies supported this hypothesis by showing stress-induced increases in alcohol's absolute value. However, from a value-based decision-making perspective alcohol's value relative to alternatives should be more relevant for drinking decisions. We developed a novel experimental paradigm that subjected the hypothesis to a more stringent test by examining whether acute stress causes individuals to choose alcohol over appealing non-alcoholic alternatives, and the cognitive mechanisms that underpin this. Participants (N=160) rated various drinks and made repeated choices between alcoholic and non-alcoholic options before and after randomized manipulations of stress and alcohol intoxication (BrAC=.06%). Using drift diffusion modeling, we decomposed choices into three potential mechanisms: decision carefulness, evidence sensitivity, and alcohol bias. Results showed that stress moderately increased choices for alcohol, but only in sober participants. Stress primarily affected decision-making by inducing a bias toward alcohol during evidence accumulation, without impacting decision carefulness or general evidence sensitivity. This computational bias was stronger than observed in raw choice behavior, suggesting that while stress consistently biases evaluation toward alcohol, this bias only sometimes overcomes competing considerations. The boundary condition that stress effects appeared only in sober participants suggests the tension reduction hypothesis may primarily explain initial drinking decisions rather than choices about continued consumption. These findings advance our mechanistic understanding of how stress influences alcohol-related decision-making and suggest interventions might focus on strengthening competing motivations during high-stress moments, particularly during decisions about initiating drinking episodes
Powell.pps: Close & Distant Reading of Primary Sources in Web Archives
Colin Powell’s 2003 PowerPoint presentation to the U.N. Security Council on Iraq’s nuclear capabilities has been analyzed from multiple perspectives as a key moment in early 21st century history. Examining the presentation file and its traces in web archives provides an opportunity to develop approaches to working with web-based born-digital primary sources. Connecting work in platform studies with scholarship on web archives, this study provides additional context for understanding both the presentation and public policy communications at the turn of the 21st century, as well as context for developing and advancing historical research methods for working with web archives

Honor, Gender, and Leadership Style
Implicit Leadership Theory (ILT) states that members of a culture will share prototype-based conceptualizations of the concept of “leadership,” against which individuals and behaviors will be evaluated (Epitropaki et al., 2013; Lord et al., 2020).
This research represents one part of a broader program examining ILT as a function of culture of honor, a cultural belief system placing central value on the gaining, maintenance, and defense of reputation (for reviews see Brown, 2016; Uskul et al., 2019).
This study specifically examines honor in relation to specific leadership prototypes derived from a previously-established ILT framework, the Global Leadership and Organizational Behavior Effectiveness (GLOBE) leadership dimensions, as well as examining how these relationships are affected by and in turn influence gender preferences in leadership
Lifespan - Midlife
Research activities concering well-being and personal growth during midlife.
Midlife or the middle period in the life course appears to be the least studied age category in (life course) psychology (Infurna, Gerstorf & Lachman, 2020). Yet, the level of well-being during this period influences not only individual functioning but also that of others (Lachman et al., 2015). In the middle years of life, most (social) roles are fulfilled, and the way these roles are carried out also affects the well-being of others (e.g., children, parents).
Midlife roughly encompasses the period between the ages of 40 and 60. According to several cross-sectional studies, this is a time when a dip in life satisfaction may occur (e.g., Blanchflower & Oswald, 2008; Stone, Schwartz, Broderick, & Deaton, 2010). Longitudinal research presents a more varied picture. Some studies show that well-being remains relatively stable during this period and that emotional well-being even appears to increase (Baird, Lucas, & Donnellan, 2010; Galambos, Fang, Krahn, Johnson & Lachman, 2015). Other research finds a dip in emotional well-being around age 50, followed by an increase; for social and psychological well-being, dips were found at approximately age 40 and 65, respectively (Lataster et al., 2022).
Although many questions remain regarding well-being in midlife and the myth of the midlife crisis persists (despite lacking scientific support), it is clear that maintaining well-being during this period is important—not only for the middle-aged individual but also for their surrounding environment
How Does the Pro-Beijing Media Influence Voter Behavior and Opinion? An Online Field Experiment during Taiwan’s 2020 Presidential Election
Tests of a Hybrid-Similarity Exemplar Model of Context-Dependent Memorability in a High-Dimensional Real-World Category Domain
We conduct tests of a hybrid-similarity exemplar model on its ability to account for the context-dependent memorability of items embedded in high-dimensional category spaces. According to the model, recognition judgments are based on the summed similarity of test items to studied exemplars. The model allows for the idea that “self-similarity” among objects differs due to matching on highly salient distinctive features. Participants viewed a study list of rock images belonging to geologically defined categories where the number of studied items from each category was manipulated. Following study, the participants’ old-new recognition memory performance was tested. We also manipulated across experiments the nature of the encoding task used during the study phase: Experiment 1 used a category-description matching task, whereas Experiment 2 used more neutral encoding instructions. Hit rates were markedly lower in Experiment 2 than in Experiment 1 and participants relied less on the presence of distinctive features for recognizing old items in the second experiment. With a minimum of parameter estimation, the hybrid-similarity model provided good accounts of a wide variety of fundamental benchmark phenomena across the two experiments. These included changing levels of memorability due to contextual effects of category size, within- and between-category similarity, and the presence of distinctive features. However, the hybrid model and a variety of extensions of the model fell short in accounting for the variability in hit rates within the class of old target items themselves. We discuss future directions for potentially improving upon the current predictions from the model
