Positive Recovery Journaling: An Intervention to Support Recovery from Substance Use Disorders
Amy Krentzman, University of Minnesota

Dr. Krentzman will describe her development of Positive Recovery Journaling (PRJ). PRJ is based on positive psychology and behavioral activation and is designed to be a group intervention integrated into substance use disorder treatment. Dr. Krentzman will review the current research on journaling, positive psychology, and behavioral activation, and the results of three studies of PRJ. Research has shown that those who used PRJ who had fewer than 90 days of sobriety experienced greater satisfaction with life, happiness with recovery, and quality of life, and lower levels of negative affect and depression, compared with the control group. Counselors rated PRJ as highly feasible, acceptable, and appropriate. Throughout the presentation, participants will have the opportunity to practice some of PRJ’s components, so feel free to have a pen and paper ready!

What moderates effect sizes in education? A meta-epidemiological study
Ignacio Atal, Université Grenoble Alpes

With the rise of evidence-based education in policy in the past decades, a strong focus has been put in the conduct of randomised controlled trials or quasi-experimental studies. This is accompanied by an increasing number of meta-analyses to quantitatively summarize the results from those studies. Meta-analyses are of particular interest to test the generalisability of research results, but also to identify sources of heterogeneity from apparently conflicting studies. In fact, a study examining a teaching practice may show different results when implemented differently, in different contexts, on different populations, or evaluated through different outcomes (Cheung & Slavin, 2016; Kraft, 2020). Thus, the effect of a teaching practice quantified by a study may not only depend on the teaching practice itself, but also on several methodological features of studies. The extent to which the existing evidence is biased because studies overestimate effects purely methodologically is currently unknown.
In this presentation, we will describe a protocol (and possibly preliminary results) of a meta-epidemiological study aiming at identifying study characteristics (also called moderators) that persistently affect effect sizes in education. We will rerun 247 meta-analyses (including more than 11 000 studies) included in a recent meta-review (Pellegrini et al., 2024), and test if some moderator effects persist between meta-analyses.

Ignacio Atal holds a PhD in Public Health and Epidemiology from Université Paris Descartes. His thesis questioned the mismatch between medical research efforts and public health priorities worldwide. As a Long-term research fellow at the Learning Planet Institute (formerly CRI-Paris), Université Paris Cité, he created and coordinated the Profs-Chercheurs programme (profschercheurs.org). Profs-Chercheurs is a programme based on citizen science and collective intelligence, which aims at supporting geographically distant educators in tackling common professional challenges thanks to research methods and a dedicated collaborative platform. He recently joined LaRAC, Université Grenoble Alpes, to lead a critical analysis of the way meta-analyses are undertaken in education.

Decisional components in motor-response execution
Michele Scaltritti, University of Trento (Italy)

Everyday experience suggests that thoughts and actions are tightly intertwined and continuously interact. However, cognitive sciences have often assumed a temporal and functional priority of cognition over action, with motor behaviors serially following the termination of (prior) cognitive computations.
The present research project assessed the functional specificity of the decisional components unfolding during response execution. Methodologically, over a series of lexical decision experiments the electromyographic (EMG) traces of manual responses were used to obtain chronometric measures of response (button-press) duration. The results revealed that the slower response times for pseudowords compared to words include a slower execution of the motor-response. This lexicality effect during motor-response execution is however independent from manipulations of speed-accuracy tradeoffs and response bias, as well as from metacognitive evaluations of decisional confidence. Taken together, the results suggest that decisional processes are still unfolding during motor-response execution. Further, they seem to point toward a certain degree of independence between the decisional variables influencing premotor vs motor intervals within response times. Rather than a nuisance variable, motor execution may thus provide unique insights into unfolding decisional processes.

Effect of childhood hearing loss on the subcortical and cortical processing of speech
Axelle Calcus, Université libre de Bruxelles

How does a peripheral, mild to moderate, sensorineural hearing loss (MM HL) affect central auditory processing along the auditory pathway? The answer appears to vary depending on the stimulation strategy. In the absence of any amplification, MM HL appears to entail some changes in the cortical processing of sounds that manifest themselves in late childhood/adolescence. More recently, we conducted a study aimed at examining the effect of childhood MM HL and the benefit of frequency-specific amplification on both subcortical and cortical auditory processing, and to relate it to speech-perceptual abilities. We recorded subcortical and cortical responses to speech syllables in nineteen children with congenital MM HL (unamplified and amplified), and sixteen children with typical hearing (unamplified sounds only). Speech perception was measured behaviourally. Congenital HL led to smaller subcortical and cortical responses to unamplified speech sounds. There was a significant benefit of amplification on subcortical and early, but not late, cortical responses, with some effects differing across age. No relationship was found between the neural and behavioural measures. Childhood MM HL thus affects both subcortical and cortical processing of speech. Amplification mostly benefits subcortical processing of speech in younger children. Childhood HL leads to functional changes in the processing of sounds, with amplification differentially affecting subcortical and cortical levels of the auditory pathway. Together, our results support the existence of multiple gain mechanisms that could underlie homeostatic plasticity throughout the auditory pathway in the context of childhood hearing loss.

When the Bot Walks the Talk : Etude des fondements de la confiance dans l’intelligence artificielle
Fanny Lalot, Université de Bâle

Le concept de confiance dans l’intelligence artificielle (IA) prend une importance croissante pour comprendre et façonner les interactions entre humains et machines. Malgré les avancées récentes, la question de savoir si les processus de confiance dans l’IA sont similaires à ceux de la confiance interpersonnelles (dans les autres humains) reste controversée. Je présenterai les résultats d’une étude récente qui a testé un modèle intégratif de la confiance inspiré de la recherche sur la confiance interpersonnelle, englobant la confiance, ses antécédents (propension à faire confiance et fiabilité perçue), et ses conséquences (intentions d’utiliser l’IA et de partager des informations personnelles). L’étude s’est également intéressée au rôle de la personnalisation de l’IA sur la confiance et la fiabilité, en tenant compte à la fois de différences de moyennes (ou niveaux) et de relations dynamiques. Les résultats seront discutés en termes d’implications pour la recherche sur la confiance dans les humains et dans la robotique.

Sharing personal memories on social media: Motives and (some) mnemonic consequences
Charles B. Stone, John Jay College of Criminal Justice, The City University of New York

Social media has become a powerful and efficient means by which individuals share their personal memories with friends, family, and the world at large. Despite this, researchers are only beginning to examine the motives and mnemonic consequences associated with sharing personal experiences via social media--both for the producer (i.e., the person posting the material) and the consumer (i.e., the individual viewing the material; see Stone & Wang, 2019). The aim of the present talk is (generally) threefold: 1) briefly review the research examining the psychological motives and mnemonic consequences associated with producing or sharing content on social media, 2) present the latest research from our lab and colleagues extending these lines of research, and 3) discuss methodological considerations associated with conducting social media research in terms of attrition rates, ecological validity and the evolving nature of social media itself and present avenues for future research.

Le climat scolaire peut-il vraiment être la réponse à tous les maux ?
Clément Perrin, Université Grenoble Alpes

Le climat scolaire est un sujet particulièrement populaire chez les professionnels de l'éducation mais aussi chez les chercheurs. Pour autant, il est difficile de trouver une définition consensuelle du climat ce qui témoigne des difficultés rencontrées par ce champ de la recherche. Cette présentation abordera les premiers résultats du travail de thèse et les questions de recherche suivantes : Peut-on définir (et mesurer) le climat scolaire d'un établissement ? Le climat scolaire est-il associé à des variables cibles, nous distinguerons les variables scolaires (motivation, notes...) des variables plus générales (sommeil, santé, bien-être) ? Enfin, le climat scolaire varie-t-il entre les établissements (analyses multiniveaux) ? Nous discuterons des liens étroits entre ces trois questions, plus particulièrement de l'apport des analyses multiniveaux, ainsi que des implications pour la recherche et les professionnels.

Value formation in the school context: Insights from recent studies in Europe and beyond
Anna Doering, University of Westminster

Human values – the broad motivational goals that are important to a person and guide them in life (e.g., kindness, curiosity, compassion) – are at the core of primary school curricula and educational frameworks worldwide (UNESCO, 2020). Indeed, values have been highlighted by European institutions (Council of Europe, 2016) as well as international bodies (OECD, 2019; UN, 2015) to be important in these and other contexts. In sharp contrast to the key role values play in primary school education, very few empirical studies have collected data on values at an early age, and this gap in research is particularly wide in the primary school years. However, exciting data from around the globe have emerged very recently (e.g., Döring et al., 2024, special issue in the European Journal of Psychology of Education), which will be the focus of this presentation. Being conceptually grounded in Schwartz’s (1992) cross-cultural theory of human values and Makarova et al.’s (2024) socio-ecological model of values education in school, the presentation will explore value developmental and value transmission in the primary school years and review how children’s values predict their behaviour in the classroom. The presentation will also highlight the impact of factors in the classroom (e.g., the classroom climate, peers’ values), the school (e.g., the headteacher), and the wider context (e.g., national school curricula) on children’s value priorities (i.e., the importance children assign to certain values) emerging from longitudinal studies with large samples using a variety of approaches (e.g., multilevel, latent growth, interviews). The presentation will conclude with detailing several routes to impact (e.g., teacher training and educational policies).

Soutenir les pratiques parentales et enseignantes par la formation en ligne : deux initiatives québécoises
Stéphane Duchesne, Université Laval, Canada

Les besoins psychologiques jouent un rôle clé dans la motivation, l’apprentissage et le bien-être des jeunes (Ryan et al., 2023). Si les parents et les enseignant(e)s peuvent les nourrir grâce à des pratiques soutenantes, une approche trop contrôlante risque au contraire de les brimer. Toutefois, adopter ces pratiques ne va pas de soi : il est essentiel de proposer des solutions accessibles et efficaces pour aider les parents et les enseignant(e)s à en comprendre l'importance et à les intégrer dans leur quotidien. Ces dernières années, les formations en ligne se sont imposées comme une option prometteuse. Pourtant, aucune ne met spécifiquement l’accent sur les pratiques favorisant les besoins psychologiques des jeunes. Cette présentation exposera deux initiatives développées dans cette perspective : les formations MAXIME (Maximiser l’impact de mon encadrement) et COMÈTES (Comment optimiser la motivation des élèves en transition à l’école secondaire). Les protocoles d’évaluation de leurs impacts seront également abordés, ainsi que les résultats de la formation MAXIME.

Does Providing or Receiving Peer Feedback Affect Students Differently?
David Zamoro Sande, University of Deusto (ERLA Research Group)

Is it more beneficial to provide or receive peer feedback? Peer feedback has been extensively studied over the last few decades, likely due to its demonstrated positive impact on students’ outcomes (e.g., academic performance). However, while students often act in both roles, providers and recipients, one fundamental question remains unresolved: do these roles have a different impact on student outcomes?
To address this question, we began by conducting a systematic review and meta-analysis of the existing evidence. There have been some assumptions about the differences between these roles, such as the idea that providing feedback is more beneficial. Other studies have hypothesized that the internal processes students engage in differ between roles, which could explain their varying impacts. However, our review showed that most of these claims lack robust empirical support, and the available findings are inconclusive.
To fill this gap, we conducted two empirical studies with independent samples in distinct contexts. These studies resulted in three research outputs: two focused on comparing the effects of the roles on outcomes such as performance, perceived learning, and perceived trust, while the third examined internal processes through the analysis of think-aloud protocols (TAP).
Preliminary findings suggest that differences between roles in terms of task performance and perceived learning & trust are not significant within the analyzed samples. However, when examining the process through concurrent measures (e.g., TAP), clear differences emerge in the actions students activate while engaging in these roles, shedding light on previously unsubstantiated assumptions. In addition to these findings, the development of the studies posed notable challenges, particularly in the design and integration of concurrent measures such as think-aloud protocols, which will also be discussed in this talk.

How long does it take to burn out? The origins of parental burnout during couples' transition to parenthood  
Konrad Piotrowski, PhD, Center for Research on Personality - Development Institute of Psychology, SWPS University, Warsaw, Poland 

Parental burnout, a state of chronic exhaustion related to the parenting role, has been extensively studied in recent years. However, one fundamental question remains unanswered: how long does it take to burn out as a parent? Most existing research on parental burnout examines individuals who have already been parents for months, years, or even decades, leaving the critical early stages of parenthood unexplored. These initial stages may hold essential clues about the origins of parental burnout and its trajectory. To address this gap, we designed a longitudinal, dyadic study (the Polish Longitudinal Study of Dyads; PL-STUDY; https://osf.io/jmbke) that begins during the second or third trimester of pregnancy and follows couples through the first three years of their child’s life. Our sample includes 234 first-time parental dyads (a woman and a man) recruited from Poland. Using a dyadic perspective allows us to examine the interplay between partners' experiences and the mutual influences that shape their psychological well-being. Thus far, we have completed seven measurements, spanning from pregnancy through the first 12 months postpartum. This design provides a unique opportunity to investigate how burnout emerges and develops from the earliest stages of the parenting journey.

Preliminary findings are concerning, as they indicate that for some parents, burnout can develop almost concurrently with their parenting role and persist throughout. This suggests that the history of parental burnout may, for some, be as long as their history of parenthood itself. The implications of this are significant, not only for the mental health and well-being of parents but also for the developmental outcomes of their children. Persistent parental burnout poses a serious risk to family dynamics, parent-child relationships, and overall family functioning. Our study underscores the importance of early interventions and preventive measures to support parents during the transition to parenthood. These findings highlight the urgent need for further research into the precursors and predictors of parental burnout and for developing strategies to mitigate its long-term effects on families.

Language, exactness, and the compositional structure of number words
David Barner, UC San Diego (USA)

What is the origin of the human ability to represent large numbers exactly? In this talk, I argue that it derives from three core capacities: (1) the ability to treat words, text, beads, or fingers as symbols, (2) the ability to place symbols and objects into one-to-one correspondence, and (3) the ability to compose these symbols syntactically. Prior to mastery of a compositional counting system, young children and non-numerate adults can often label and reason about small exact numbers, but are restricted to representing, comparing, and matching large sets approximately. Also, even children who know some number words and who can accurately count often don't seem to know that large number words must represent number exactly. I argue that a key to unlocking large exact number concepts is the ability to syntactically combine symbols that represent smaller quantities in order to represent larger ones. I show that mastering the syntax of number words allows children to understand that ever-larger numbers can be created, and that numbers must therefore never end. This learning varies cross-linguistically depending on how easy it is to notice the structure of number words, and can be trained in the lab in much younger children, when simplified counting systems are invented.
