Alzheimer's disease (AD), the most common neurodegenerative disorder world-wide, presents sex-specific differences in its manifestation and progression, necessitating personalized diagnostic approaches. Current procedures are often costly and invasive, lacking consideration of sex-based differences. This study introduces an explainable machine learning (ML) system to predict and differentiate the progression of AD based on sex, using non-invasive, easily collectible predictors such as neuropsychological test scores and sociodemographic data, enabling its application in every day clinical settings.

Why social norms may fail us when we need them most.

Curr Opin Psychol

December 2024

Institute of Cognitive Sciences and Technologies, National Research Council of Italy, Rome, Italy; Institute for Futures Studies, Stockholm, Sweden; Institute for Analytical Sociology, Linkoping University, Sweden.

Where social norms are the 'glue' guiding behavior, people hardly think of their behavior as an act of norm compliance. They do consciously look for social norms in situations of environmental or social uncertainty, because i) norms provide behavioral cues that reduce uncertainty and ii) the uncertainty is partially induced by the lack or instability of social norms themselves-creating the (flawed) perception that social norms often fail us when we need them most. We discuss several state-of-the-art conceptualizations of social norms-abstract and specific norms, the social norms life cycle, and social norms in changing contexts-to highlight where and how uncertainty comes into play within each of these approaches, and consequently where the success of social norms might be hindered.

Generative models for sequential dynamics in active inference.

Cogn Neurodyn

December 2024

Institute of Cognitive Sciences and Technologies, National Research Council, Via S. Martino Della Battaglia, 44, 00185 Rome, Italy.

A central theme of theoretical neurobiology is that most of our cognitive operations require processing of discrete sequences of items. This processing in turn emerges from continuous neuronal dynamics. Notable examples are sequences of words during linguistic communication or sequences of locations during navigation.

Understanding and predicting human cooperative behaviour and belief dynamics remains a major challenge both from the scientific and practical perspectives. Because of the complexity and multiplicity of material, social and cognitive factors involved, both empirical and theoretical work tends to focus only on some snippets of the puzzle. Recently, a mathematical theory has been proposed that integrates material, social and cognitive aspects of behaviour and beliefs dynamics to explain how people make decisions in social dilemmas within heterogeneous groups.

Humans can perform exquisite sensorimotor skills, both individually and in teams, from athletes performing rhythmic gymnastics to everyday tasks like carrying a cup of coffee. The "predictive brain" framework suggests that mastering these tasks relies on predictive mechanisms, raising the question of how we deploy such predictions for real-time control and coordination. This review highlights two lines of research: one showing that during the control of complex objects people make the interaction with 'tools' predictable; the second one examines dyadic coordination showing that people make their behavior predictable for their partners.

Background And Aim: Most children and adolescents with deafness receive one or two cochlear implants (CIs). Despite the CI expanding the potential for auditory rehabilitation in deaf children, the improvements in language and literacy skills of some of these children do not align with the expected outcomes. As the main research question, we wondered if the reading and writing deficits reported in some deaf children with CIs may be characterized as a domain-specific learning disorder, rather than only a consequence of deafness.

Cognitive problem-solving benefits from cognitive maps aiding navigation and planning. Physical space navigation involves hippocampal (HC) allocentric codes, while abstract task space engages medial prefrontal cortex (mPFC) task-specific codes. Previous studies show that challenging tasks, like spatial alternation, require integrating these two types of maps.

Approach to Complementary Feeding and Infant Language Use: An Observational Study.

Matern Child Nutr

January 2025

School of Psychology, Institute of Health and Neurodevelopment, Aston University, Birmingham, UK.

Emerging research suggests that a more infant-led approach to complementary feeding may confer benefits for child language, but these findings are based on parent report studies. Using an observational approach this study examines whether different complementary feeding experiences relate to infant language exposure and language use. Fifty-eight parents recorded a typical infant mealtime in the home (mean infant age = 14 months, SD = 4.

Understanding the psychophysiological state during robot-aided rehabilitation is crucial for assessing the patient experience during treatments. This paper introduces a psychophysiological estimation approach using a Fuzzy Logic inference model to assess patients' perception of robots during upper-limb robot-aided rehabilitation sessions. The patients were asked to perform nine cycles of 3D point-to-point trajectories toward different targets at varying heights with the assistance of an anthropomorphic robotic arm (i.

A tradeoff exists when dealing with complex tasks composed of multiple steps. High-level cognitive processes can find the best sequence of actions to achieve a goal in uncertain environments, but they are slow and require significant computational demand. In contrast, lower-level processing allows reacting to environmental stimuli rapidly, but with limited capacity to determine optimal actions or to replan when expectations are not met.

Recent views recognize that abstract concepts encompass a variety of exemplars, each relying on different dimensions, including not only sensorimotor but also inner, linguistic, and social experiences. How these dimensions characterize types of abstract concepts, and whether their weight varies across contexts and individuals remains an open question. We investigated the role of linguistic and social situations in the processing of institutional concepts, such as justice, by individuals with different levels of expertise.

Transitive inference (TI) is a cognitive task that assesses an organism's ability to infer novel relations between items based on previously acquired knowledge. TI is known for exhibiting various behavioral and neural signatures, such as the serial position effect (SPE), symbolic distance effect (SDE), and the brain's capacity to maintain and merge separate ranking models. We propose a novel framework that casts TI as a probabilistic preference learning task, using one-parameter Mallows models.

Article Synopsis
  • Repeat expansions in the C9orf72 gene are a leading genetic cause of ALS and frontotemporal dementia, but understanding how this mutation causes neuron death is still unclear, complicating the search for effective therapies.
  • Researchers analyzed data from over 41,000 ALS and healthy samples to identify potential treatments, discovering that acamprosate, a drug used for other conditions, might be repurposed for C9orf72-related diseases.
  • Their findings demonstrated that acamprosate has neuroprotective properties in cell models and works similarly well as the current treatment, riluzole, showing the potential of using genomic data to find new drug applications.

Introduction: Pavlovian fear conditioning is an experimental paradigm used to study the acquisition and extinction of fear responses and the various aspects of fear and anxiety. We developed a virtual reality (VR) version of this paradigm to leverage the benefits of virtual reality, such as ecological validity, standardization, safety, and therapeutic applications. Our objective was to create an open-source and immersive environment for studying fear-related responses using Unity Engine 3D and the Oculus Rift device.

Article Synopsis
  • - Efficient sensory detection involves ignoring irrelevant information, like separating self-movement from object perception, using a model based on predictive coding and sensorimotor mismatch detection.
  • - Researchers created a model with a three-neuron circuit that shows how these mismatch responses occur, integrating this into a broader neural network with two streams that predict self-generated optic flow and process external movement cues.
  • - The model allows for the segmentation of objects from their background and supports object categorization, showing similarities between the neural processes in different species, including primates.

Playing music is a complex task that relies on the combination of musicians' technical and expressive skills. While the literature has investigated the effects of musical expressivity on the listeners, the way how technical difficulty and emotional expressivity affect musicians during playing has surprisingly received no attention. In an attempt to fill this gap in the literature, we collected behavioral and physiological data from twelve violinists playing 29 pieces that included both technical exercises and excerpts from classical repertoire for violin.
