Fourteen-Month-Olds Adapt Their Imitative Behavior in Light of a Model’s Constraints

Kata Gellén, David Buttelmann · 2017 · Child Development Research

Rather than reenacting every action they observe, preverbal infants adapt their imitative behavior. Although previous studies have revealed the capability of preverbal infants to imitate selectively, the question about the adaptability of this behavior on an individual level did not attract considerable scientific attention until now. In the current study, we investigated whether 14-month-old infants flexibly alternate their imitative response in accordance with a model’s changing physical constraints in a body-part imitation paradigm. Participants were presented with two novel actions whereby

A Cognitive Approach to the Instruction of Phrasal Verbs: Rudzka-Ostyn’s Model

Ghuzayyil Mohammed Al-Otaibi · 2019 · Journal of language and Education

English as a Foreign Language (EFL) learners find some phrasal verbs problematic because of their idiomatic and polysemous nature. They are frequently used in spoken English and textbooks suggest an arbitrary way in teaching them. Cognitive linguists proposed that the particle plays a major role in determining the meaning of such phrasal verbs. This study investigated the effectiveness of a cognitive approach (i.e., Rudzka-Ostyn’s Model) in teaching taught and new phrasal verbs including metaphorical ones. Using a list of frequent phrasal verbs, a quasi-experimental design was used in which an

Effectiveness and moderators of individual cognitive behavioral therapy versus treatment as usual in clinically depressed adolescents: a randomized controlled trial

Yvonne Stikkelbroek, Gerko Vink, Maaike H. Nauta et al. · 2020 · Scientific Reports

We examined if manualized cognitive behavioral therapy (CBT) was more effective than Treatment As Usual (TAU) for clinically depressed adolescents within routine care. This multisite Randomized controlled trail included 88 clinically depressed adolescents (aged 12-21 years) randomly assigned to CBT or TAU. Multiple assessments (pre-, post treatment and six-month follow-up) were done using semi-structured interviews, questionnaires and ratings and multiple informants. The primary outcome was depressive or dysthymic disorder based on the KSADS. Completers, CBT (n = 19) and TAU (n = 26), showed a

LLM-powered socially assistive robot-delivered cognitive behavioral therapy exercises: an exploratory study with university students

Mina Kian, Mingyu Zong, Katrin Fischer et al. · 2026 · Frontiers in Robotics and AI

Mental health is a significant healthcare challenge, and cognitive behavioral therapy (CBT) is a widely used therapeutic method for treating anxiety and depression. However, traditional CBT often requires access to trained clinicians and can be cost-prohibitive or logistically difficult for many individuals. To address these barriers, we developed a low-cost socially assistive robot (SAR) that uses a large language model (LLM) to guide the user through interactive at-home CBT exercises. In this exploratory study, 38 university students completed CBT exercises across a 15-day period using one o

SΔϕ-60 — Utilitarian Subject-Splitting Index

Sofience · 2026 · Zenodo (CERN European Organization for Nuclear Research)

SΔϕ-60 introduces the Utilitarian Subject-Splitting Index, USSI, within the Sofience-Δϕ Formalism. The paper examines whether utilitarian calculation merely evaluates the happiness of already-existing majorities and minorities, or whether such calculation can first produce the operational boundary between majority and minority by redistributing Transition Completion Cost, TCC. The document begins with the Sofience Subject Thought Experiment. A person is imagined as capable of detaching and reattaching any part of the body while the detached parts remain alive, neurologically connected, and phy

Measuring Semantic Deviation: Operationalizations, Experiments, and Falsification Conditions for a Theory of Meaning as Field Deformation

Nobel Glas · 2026 · Zenodo (CERN European Organization for Nuclear Research)

EA-GLAS-02 v1.0. A self-contained empirical white paper presenting the measurement program for the Semantic Deviation Principle (Sharks 2026). Defines meaning as the time-integrated divergence a sign induces from the most probable trajectory of a semantic field, extending the Bar-Hillel and Carnap (1953) program into distributional and temporal domains. Two primary operationalizations. (F1) Closed-system trajectory deviation within a frozen language model, where the counterfactual baseline is read from logits, building on surprisal theory (Hale 2001; Levy 2008) and decomposing it into signed d

Examining the reliability and validity of two versions of the Effort-Expenditure for Rewards Task (EEfRT)

Hanno Andreas Ohmann, Niclas Kuper, Jan Wacker · 2022 · PLoS ONE

The Effort-Expenditure for Rewards Task (EEfRT) has gained validity evidence from several studies. However, various modifications have been applied to the original version, which have never been compared systematically. In Study 1, we tested 120 healthy participants to directly compare two versions of the EEfRT. In Study 2, we tested a larger sample of 394 healthy participants to further examine the original EEfRT. We replicated the split-half reliability of both task versions. However, self-reported personality traits (e.g., trait BAS) correlated with only some task performance parameters in

Testing the Magnitude of Correlations Across Experimental Conditions

Simone Di Plinio · 2022 · Frontiers in Psychology

Correlation coefficients are often compared to investigate data across multiple research fields, as they allow investigators to determine different degrees of correlation to independent variables. Even with adequate sample size, such differences may be minor but still scientifically relevant. To date, although much effort has gone into developing methods for estimating differences across correlation coefficients, adequate tools for variable sample sizes and correlational strengths have yet to be tested. The present study evaluated four different methods for detecting the difference between two

Shedding light on relations between teacher emotions, instructional behavior, and student school well-being – Evidence from disadvantaged schools

Julia Holzer, Luisa Grützmacher, Marko Lüftenegger et al. · 2024 · Learning and Instruction

Despite broad theoretical consensus on the direct and indirect relevance of teacher emotions for instructional behavior and student outcomes, empirical evidence is inconclusive. Moreover, there is limited research in this area involving disadvantaged and younger student populations, and addressing students’ school well-being as an outcome explicitly. This study investigates associations between teacher emotions (joy, anger, anxiety), teacher-reports of instructional behavior (cognitive and motivational stimulation, classroom management, and social support), and students' reported school well-b

A network analysis of female sexual function: comparing symptom networks in women with decreased, increased, and stable sexual desire

Annika Gunst, Marlene Werner, Lourens Waldorp et al. · 2018 · Scientific Reports

Problems related to low sexual desire in women are common clinical complaints, and the aetiology is poorly understood. We investigated predictors of change in levels of sexual desire using a novel network approach, which assumes that mental disorders arise from direct interactions between symptoms. Using population-based data from 1,449 Finnish women, we compared between-subject networks of women whose sexual desire decreased, increased, or remained stable over time. Networks were estimated and analyzed at T1 (2006) and replicated at T2 (2013) using R. Domains included were, among others, sexu

Communicating Evidence about the Causes of Obesity and Support for Obesity Policies: Two Population-Based Survey Experiments

James P. Reynolds, Milica Vasiljevic, Mark Pilling et al. · 2020 · International Journal of Environmental Research and Public Health

Public support for numerous obesity policies is low, which is one barrier to their implementation. One reason for this low support is the tendency to ascribe obesity to failings of willpower as opposed to the environment. Correlational evidence supports this position. However, the experimental evidence is mixed. In two experimental studies, participants were randomised to receive no message, messages about the environment’s influence on obesity (Study 1 & 2), or messages about the environment’s influence on human behaviour (Study 1). We investigated whether communicating these messages cha
