Beyond Satisfaction: Learning Associations Between Content, Reviews, and Well-Being

arXiv:2607. 02539v1 Announce Type: cross Abstract: Digital platforms commonly optimize for satisfaction using signals such as ratings, likes, and sentiment, implicitly treating satisfaction as a proxy for user well-being.

The psychophysics of affect in large language models

The study examines how large language models (LLMs) predict the emotional impact of outcomes in gambling and stock-trading scenarios and whether these predictions influence their decision-making. When outcomes are evaluated alone, LLMs show diminishing sensitivity to magnitude—similar to human value functions—but they amplify gains relative to losses, a phenomenon termed silicon gain amplification. When outcomes are compared directly, the ratings become linear, and in choice tasks the gain-loss asymmetry largely disappears, with the models’ affective ratings not providing a better explanation of choices than monetary utility alone.

Affective Context Amplifies Sycophancy in LLM Responses

arXiv:2608.21242v1 Announce Type: new Abstract: As conversational companions, large language models (LLMs) often have access to users' emotional states. We study how this affective context modulates...

Whose Assessment of Distress? Community Perspectives and LLM Alignment on Well-Being Posts

The study investigates how large language models (LLMs) assess psychological distress in online posts from six identity‑based communities. Through a perspectivist annotation task, 321 participants provided 9,587 judgments on 1,198 Reddit posts, revealing modest in‑group agreement (OR = 1.18) that varies across communities. When evaluated against these community‑specific labels, open‑weight LLMs consistently over‑estimate distress—achieving only 31–44% accuracy on posts perceived as none‑to‑mild—while newer models like GPT‑5 and Gemini 2.5 Pro show similar inflation, whereas Claude Opus 4 is more conservative. "whyItMatters":"The findings highlight that miscalibrated distress detection by LLMs can disproportionately impact the very communities they aim to serve, underscoring the need for equitable AI deployment in mental‑health contexts."

semanticfa: An R Package for Response-Free Semantic Factor Analysis of Psychometric Scales

The paper introduces semanticfa, an R package that performs semantic factor analysis on psychometric scales by converting items into language‑model embeddings and factoring their similarities. It demonstrates the method on the 50‑item International Personality Item Pool Big‑Five markers, compares the semantic factors to a large response‑based factor analysis, and shows how the package can interpret factors, flag redundant items, build short forms, and screen new items. The authors propose semantic‑behavioral coherence as a measurable property of a scale, noting that semantic factor analysis complements but does not replace traditional response‑based factor analysis.
