Finding: People tend to compromise rather than counteract their partners in risky joint decision-making, especially when preferences diverge, and this compromise behavior can be modeled through reinforcement learning that integrates both partners' preferences while being influenced by egocentric biases in responsibility attribution.

Why it matters: This directly informs understanding of team dynamics and collaboration under uncertainty, revealing how individual differences in risk tolerance and attribution biases affect collective decision-making and coordination.

Method: Novel dyadic foraging paradigm with computational modeling using reinforcement learning to explain compromise behavior, combined with responsibility attribution measures across exploratory and confirmatory studies.

Jargon: Dyadic foraging - two-person decision-making task involving choices between risky reward locations; egocentric bias - tendency to claim more credit for successes than blame for failures.

Finding: Personalization algorithms in e-commerce use dark patterns that significantly distort consumer decision-making, with cognitive biases (especially loss aversion) serving as key mediating factors between manipulative interface design and poor decisions.

Method: Scenario-based survey with 212 e-commerce users analyzed using PLS-SEM to examine relationships between dark patterns, cognitive biases, and decision distortion.

Jargon: Dark patterns = manipulative interface designs that trick users into unintended actions; Loss aversion = tendency to prefer avoiding losses over acquiring equivalent gains; Anchoring effect = over-relying on first piece of information encountered.

Finding: Human judgments of conceptual diversity within object categories (based on function and purpose) better predict memory performance than perceptual similarity or deep neural network representations, even when controlling for visual similarity.

Why it matters: This reveals fundamental differences between human and AI conceptual organization that are crucial for designing effective human-AI interfaces and understanding how people learn and remember information.

Method: Participants sorted 498 object categories by conceptual vs. perceptual similarity, completed recognition memory tasks, and their performance was compared to predictions from CLIP, DINOv3, and VGG16 models across multiple layers.

Jargon: CLIP = vision-language model; DINOv3 = self-supervised vision model; within-category foils = similar items from same category used as distractors in memory tests.

Finding: Avalanche survivors experienced significant learning outcomes from near-death experiences, developing heightened risk awareness, more deliberate risk assessment processes, and crucially, increased recognition of their own cognitive biases in high-stakes decision-making environments.

Why it matters: This provides valuable insights into how extreme feedback experiences can overcome cognitive biases and improve decision-making under uncertainty, with applications to designing learning experiences and decision support systems.

Method: Phenomenological qualitative study using semi-structured interviews with 26 avalanche survivors, analyzed through thematic analysis.

Jargon: Phenomenological method - research approach focused on understanding lived experiences and their meanings from participants' perspectives.

Finding: This theoretical chapter proposes an integrative model showing how various affective processes (emotions, feelings, moods, motivations) shape attitudes and behaviors in intergroup conflicts, moving beyond studying discrete emotions in isolation.

Why it matters: Understanding how affect drives intergroup dynamics is crucial for designing better team collaboration systems, reducing bias in group decision-making, and creating interventions that improve cross-cultural teamwork.

Jargon: Intergroup conflict refers to tensions between different social groups; affective processes encompass all emotion-related psychological phenomena including feelings, moods, and motivational states.

Finding: Perceived importance of helping others creates a paradox where it increases stress and impairs performance, yet simultaneously motivates better action initiation in high-stakes prosocial situations through an appraisal-driven mechanism.

Why it matters: This challenges traditional compassion-based models of prosocial behavior and provides insights into how stress and perceived stakes influence collaborative behavior and helping dynamics in teams.

Method: Hybrid experimental approach using a computer-based rescue task where participants helped partners avoid electric stimulation and monetary loss, measuring self-report, behavioral performance, and psychological scales (N=53).

Jargon: Appraisal-driven account - framework explaining how cognitive evaluation of situation importance drives prosocial action; Personal distress - stress response that typically reduces helping behavior.

Finding: A computational model revealed that vigilance decrements in monitoring tasks result from three mechanisms: conservative bias shifts, increased attention lapses, and changes in guessing strategy, rather than simple sensitivity loss.

Why it matters: This provides evidence-based insights for designing interfaces and work systems that account for predictable patterns of human attention degradation over time.

Method: Used a two-boundary signal detection task with generative cognitive modeling to separate attentive vs. inattentive states and isolate specific failure mechanisms.

Jargon: Vigilance decrement = decline in detection performance during sustained attention tasks; generative model = computational model that simulates the underlying cognitive processes producing observed behavior.

Finding: This scoping review of 110 studies identifies 17 transdiagnostic predictors of job tenure for people with mental disorders, categorizing them by modifiability and stakeholder responsibility (workplace, individual/support teams, shared, or immutable factors).

Why it matters: The stakeholder responsibility framework and focus on modifiable factors provides actionable insights for designing workplace interventions and support systems that could inform HCI solutions for workplace mental health and collaboration.

Method: Systematic scoping review following PRISMA-ScR guidelines across 7 databases, screening 9,715 abstracts.

Jargon: Transdiagnostic = approach that looks across different mental health diagnoses for common patterns rather than focusing on individual disorders.

Finding: Facial gestures that convey pragmatic meaning are more effective than hand gestures mimicking pitch for helping second language learners perceive intonation patterns, though both multimodal approaches outperform audio-only training.

Why it matters: This demonstrates how different types of visual-gestural interfaces can enhance learning outcomes, providing concrete evidence for multimodal design principles in educational technology and skill acquisition systems.

Method: Controlled experiment with 61 Spanish-English learners using High Variability Perceptual Training across three conditions (hand gestures, facial gestures, no gestures), measuring pre/post performance on perception and production tasks.

Jargon: High Variability Perceptual Training (HVPT) - exposing learners to many different examples/speakers to improve pattern recognition; intonation-meaning mapping - connecting pitch patterns to communicative intent.

Finding: Single individuals experience higher day-to-day variability and instability in well-being compared to partnered individuals, but both groups show equal resilience to negative experiences when emotional support is available.

Why it matters: This research on emotional stability and support networks informs understanding of how social factors influence cognitive performance and decision-making in collaborative work environments.

Method: Four-month daily diary study with propensity-score matched samples comparing well-being dynamics between single (n=85) and partnered (n=85) young adults using statistical process control methods.

Jargon: Statistical process control - method for monitoring process stability over time to detect meaningful changes from baseline patterns.

Finding: Open science data sharing practices create "epistemic disadvantage" - structural harms to knowledge contributors that persist even in well-intentioned collaborative systems, extending beyond traditional notions of epistemic injustice to include subtler forms of knowledge extraction.

Why it matters: Relevant for understanding power dynamics in research collaboration and how supposedly equitable systems can still disadvantage certain participants, which has implications for designing fair collaborative research processes.

Method: Ethnographic study of a specific research hub (MIDEQ) examining data sharing practices and their unintended consequences.

Jargon: Epistemic injustice - unfair treatment in knowledge-related practices; epistemic disadvantage - structural vulnerabilities in knowledge sharing beyond direct injustice; extractivism - appropriation of knowledge resources without fair compensation to originators.

Finding: Proposes standardizing predictors associated with random slopes in multilevel models to simplify effect size calculation, offering a more practical alternative to complex mixture distribution approaches.

Why it matters: This methodological contribution could help behavioral science and learning sciences researchers better report and interpret effect sizes when studying hierarchical phenomena like team performance or individual learning within groups.

Jargon: Random slopes allow regression coefficients to vary across groups in multilevel models; heteroscedasticity means unequal variance across observations; mixture distribution treats variance as combination of individual group variances.
