Computational reconstruction of mental representations using human behavior.

Revealing how the mind represents information is a longstanding goal of cognitive science. However, there is currently no framework for reconstructing the broad range of mental representations that humans possess. Here, we ask participants to indicate what they perceive in images made of random visual features in a deep neural network. We then infer associations between the semantic features of their responses and the visual features of the images. This allows us to reconstruct the mental representations of multiple visual concepts, both those supplied by participants and other concepts extrapolated from the same semantic space. We validate these reconstructions in separate participants and further generalize our approach to predict behavior for new stimuli and in a new task. Finally, we reconstruct the mental representations of individual observers and of a neural network. This framework enables a large-scale investigation of conceptual representations.

Non-trivial relationship between behavioral avalanches and internal neuronal dynamics in a recurrent neural network.

Neuronal activity gives rise to behavior, and behavior influences neuronal dynamics, in a closed-loop control system. Is it possible then, to find a relationship between the statistical properties of behavior and neuronal dynamics? Measurements of neuronal activity and behavior have suggested a direct relationship between scale-free neuronal and behavioral dynamics. Yet, these studies captured only local dynamics in brain sub-networks. Here, we investigate the relationship between internal dynamics and output statistics in a mathematical model system where we have access to the dynamics of all network units. We train a recurrent neural network (RNN), initialized in a high-dimensional chaotic state, to sustain behavioral states for durations following a power-law distribution as observed experimentally. Changes in network connectivity due to training affect the internal dynamics of neuronal firings, leading to neuronal avalanche size distributions approximating power-laws over some ranges. Yet, randomizing the changes in network connectivity can leave these power-law features largely unaltered. Specifically, whereas neuronal avalanche duration distributions show some variations between RNNs with trained and randomized decoders, neuronal avalanche size distributions are invariant, in the total population and in output-correlated sub-populations. This is true independent of whether the randomized decoders preserve power-law distributed behavioral dynamics. This demonstrates that a one-to-one correspondence between the considered statistical features of behavior and neuronal dynamics cannot be established and their relationship is non-trivial. Our findings also indicate that statistical properties of the intrinsic dynamics may be preserved, even as the internal state responsible for generating the desired output dynamics is perturbed.

Funções neuropsicológicas de meninas privadas de liberdade em unidade socioeducativa / Neuropsychological functions of girls deprived of liberty in socio-educational unit / Funciones neuropsicológicos de niñas privadas de libertad en unidad socioeducativa

OBJETIVO: A avaliação neuropsicológica tem alta relevância na adolescência e em situação de conflito com a lei, com privação de liberdade em instituições socioeducativas, pode auxiliar, compondo abordagens psicossociais que identifiquem as funções neuropsicológicas, situando-as a partir da historicidade do indivíduo. Deste modo, para compreender esse problema, foi objetivo desse estudo avaliar e descrever as funções neuropsicológicas de adolescentes meninas privadas de liberdade em instituição socioeducativa. MÉTODOS: As participantes foram 19 meninas avaliadas com os instrumentos: Barratt Scale, Inventário de Expressão de Raiva, teste Wisconsin de classificação de cartas, protocolo neuropsicológico, questionário para uso de drogas e Hare Psychopathy Checklist Revised. RESULTADOS: O uso de drogas na vida ocorreu em 80,0% dos casos. Verificaram-se altos escores de impulsividade total (M=75,8, DP=5,4), traço de raiva (M=24,5, DP=7,3) e respostas perseverativas (M =38,5, DP =19,9). Em conjunto com PCL-R total (M=17,5, DP=3,6) e com QI total (M=79,1, DP=16,2), esses níveis auxiliaram na caracterização das funções de autocontrole. CONCLUSÕES: Os dados foram interpretados como indicativos de baixo funcionamento executivo, altos níveis de raiva, de impulsividade, de uso de drogas e de traços de psicopatia. Foram relatadas adversidades durante a infância, o que pode ter contribuído para um desempenho prejudicado nas funções cognitivas e emocionais dessas meninas.

OBJECTIVE: Neuropsychological assessment is highly relevant in adolescence and in situations of conflict with the law, with deprivation of liberty in socio-educational institutions, it can help, composing psychosocial approaches that identify neuropsychological functions, situating them based on the individual's historicity. Therefore, to understand this problem, the objective of this study was to evaluate and describe the neuropsychological functions of adolescent girls deprived of liberty in a socio-educational institution. METHODS: The participants were 19 girls evaluated with the following instruments: Barratt Scale, Anger Expression Inventory, Wisconsin Card Sorting Test, Neuropsychological protocol, drug use questionnaire and Hare Psychopathy Checklist Revised. RESULTS: Lifetime drug use occurred in 80.0% of cases. There were high scores for total impulsivity (M=75.8, SD=5,4), trait anger (M=24.5, SD=7.3) and perseverative responses (M=38.5, SD=19.9). Together with total PCL-R (M=17.5, SD=3.6) and total IQ (M=79.1, SD=16), these levels helped to characterize self-control functions. CONCLUSIONS: The data were interpreted as indicating low executive functioning, high levels of anger, impulsivity, drug use and psychopathic traits. Adversities were reported during childhood, which may have contributed to impaired performance in the cognitive and emotional functions of these girls.

Sampling complex social and behavioral phenomena.

We comment on the limits of relying on prior literature when constructing the design space for an integrative experiment; the adaptive nature of social and behavioral phenomena and the implications for the use of theory and modeling when constructing the design space; and on the challenges of measuring random errors and lab-related biases in measurement without replication.

A Turing test of whether AI chatbots are behaviorally similar to humans.

We administer a Turing test to AI chatbots. We examine how chatbots behave in a suite of classic behavioral games that are designed to elicit characteristics such as trust, fairness, risk-aversion, cooperation, etc., as well as how they respond to a traditional Big-5 psychological survey that measures personality traits. ChatGPT-4 exhibits behavioral and personality traits that are statistically indistinguishable from a random human from tens of thousands of human subjects from more than 50 countries. Chatbots also modify their behavior based on previous experience and contexts "as if" they were learning from the interactions and change their behavior in response to different framings of the same strategic situation. Their behaviors are often distinct from average and modal human behaviors, in which case they tend to behave on the more altruistic and cooperative end of the distribution. We estimate that they act as if they are maximizing an average of their own and partner's payoffs.

Bariatric surgery: behavioral patterns and personality disorders in the preoperative period

Introduction: Bariatric surgery has become an increasingly common procedure, especially for patients with morbid obesity who have obtained unsatisfactory results from conventional treatments. Objective: To evaluate the occurrence of behavioral patterns and personality disorders in patients in the preoperative period of bariatric surgery. Materials and methods: Cross-sectional study carried out with 146 patients from a medium-sized clinic, a reference in the execution of bariatric surgeries in the Midwest region of Minas Gerais, Brazil. Data collection was performed using the psychological instrument entitled Factorial Personality Battery. Descriptive analysis and data association were performed. Results: Half of the participants presented high or very high scores for greater propensity to develop depression and anxiety, showing a close relationship with personality disorders, especially with behavioral patterns of effort and dedication. Discussion: The patterns of effort and dedication behavior are protective factors in the postoperative period, taking into account the adaptations and new habits necessary for a good recovery and maintenance of weight loss. Conclusions: The dysfunctional patterns of behavior that stood out most are related to greater difficulty in perceiving the positive side and ease in perceiving the negative side, leading to a more intense experience of suffering, in addition to difficulty in making decisions and facing routine challenges. Screening behavioral patterns and personality disorders preoperatively is necessary for adequate patient monitoring and successful bariatric surgery.

Putting the power of behavior analysis in the hands of nonbehavioral professionals: Toward a blueprint for dissemination†.

Behavior analysts have much to offer nonbehavioral professionals who work with the communities that we serve. Successful dissemination of behavior-analytic technologies to these professionals could potentially improve their practice. Although the literature contains some exemplary examples of successful dissemination, our discipline would benefit from a blueprint for conducting this important work. In this article, I share our experiences disseminating behavioral technologies to educators, law enforcement officers, and health care providers who engage with neurodiverse individuals. These experiences form the basis of a recommended blueprint for dissemination, which awaits empirical support. After describing this tentative blueprint, I provide suggestions for future research on how best to disseminate our technologies to nonbehavioral professionals, the ideal content of those dissemination activities, and the conditions under which professionals may be more likely to embed our technologies into their best practices.

RESUMO. Este estudo tem por objetivo analisar o conhecimento de crianças e pré-adolescentes em relação aos termos que designam as forças de caráter e compreender como percebem a expressão desses traços nos próprios comportamentos e nos de outras pessoas. Foram entrevistados 17 participantes, de oito a 13 anos (M = 10,6; DP = 1,5). Para cada força foram feitas sete perguntas, que investigavam a definição do termo e exemplos da expressão da força nos outros e nos próprios entrevistados. As entrevistas foram gravadas e transcritas para análise de conteúdo, ao fim gerando categorias para cada força. As forças descritas com maior facilidade pelos participantes e suas respectivas definições foram criatividade (capacidade de criar coisas), curiosidade e amor ao aprendizado (busca de conhecimento e novas experiências), honestidade (falar a verdade), amor (comportamento de dar carinho), bondade (ajudar e cuidar do outro), trabalho em equipe (realização de trabalhos colaborativos em brincadeiras ou atividades escolares), perdão (08 categorias a respeito de sua definição, sem destaque para alguma) e esperança (desejar acontecimento futuro). Esses achados podem tornar mais acessível o desenvolvimento e a avaliação das forças nessa faixa etária.

RESUMEN. Este estudio buscó analizar el conocimiento de niños y pre-adolescentes sobre los términos que fueron designados como fortalezas de carácter, y comprender cómo perciben estos rasgos en sus proprios comportamientos y en los de otras personas. Diecisiete participantes entre ocho y trece años fueron entrevistados (M = 10.6; SD = 1.5). Para cada fortaleza, se hicieron siete preguntas, que investigaron la definición del término y ejemplos prácticos de su expresión. Las entrevistas fueron grabadas y transcritas para el análisis de contenido, creando categorías para cada fortaleza. Las fortalezas descritas por los participantes con mayor facilidad y sus respectivas definiciones fueron: creatividad (capacidad de crear cosas), curiosidad y amor por el aprendizaje (búsqueda de conocimiento y nuevas experiencias), honestidad (decir la verdad), amor (comportamientos afectivos), amabilidad (ayudar y cuidar a los demás), trabajo en equipo (desempeño del trabajo colaborativo en juegos o actividades escolares), perdón (ocho categorías con respecto a su definición, sin énfasis en ninguna) y esperanza (deseo por un evento futuro). Estos hallazgos pueden facilitar el desarrollo y la evaluación de las fortalezas con este grupo de edad.

ABSTRACT This study aims to analyze the children and pre-adolescents' knowledge regarding terms that designate character strengths and to understand how they perceive the expression of these traits in their and other people's behavior. Seventeen participants aged eight to thirteen were interviewed (M = 10.6; SD = 1.5). For each strength, seven questions were asked, which investigated the definition and examples of the strength expression. The interviews were recorded and transcribed for content analysis, generating categories for each strength. The strengths most easily described by the participants and their respective definitions were: creativity (ability to create things), curiosity and love for learning (searching for knowledge and new experiences), honesty (speaking the truth), love (acts involving affection), kindness (helping and caring for others), teamwork (collaborative works in games or school activities), forgiveness (eight categories regarding their definition, without highlighting any) and hope (longing for a future event). These findings may make developing and evaluating character strengths in this age group more accessible.

Prevalência e fatores associados ao uso de cigarro eletrônico por estudantes universitários / Prevalence and factors associated with electronic cigarette use by university students / Prevalencia y factores asociados al uso de cigarrillos electrónicos por estudiantes universitarios

Este estudo objetivou estimar a prevalência do uso do cigarro eletrônico e a associação com fatores preditores. Trata-se de um estudo transversal, analítico, com amostra probabilística de universitários matriculados em um Centro Universitário de Montes Claros, Minas Gerais, Brasil no segundo semestre de 2022. A variável dependente referiu-se ao uso do cigarro eletrônico. As variáveis independentes referiram a fatores sociodemográficas, laborais e comportamentais. A associação entre as variáveis investigadas e a prevalência do uso do CE foi verificada pela análise bivariada e a regressão de Poisson. Foram entrevistados 730 universitários, com a média de idade de anos 22,56 (±6,25). Destes, 21,8 % faziam o uso cigarro eletrônico e após a análise multivariada manteve-se associado ao desfecho não ter companheiro (RP= 3,31; IC95% 1,04-10,48), morar com amigos/sozinho (RP=1,53; IC95% 1,07-2,18), ter histórico de usuários de cigarro eletrônico na residência (RP= 1,76; IC95%: 1,17- 1,89), consumir bebida alcoólica (RP= 3,07; IC95%: 1,72-5,49) e não praticar atividade física (RP= 3,37; IC95% 2,35-4,83). Conhecer sobre o cigarro eletrônico foi fator protetor (RP= 0,31 IC95% 0,20-0,46). Registrou-se elevada prevalência do uso do cigarro eletrônico, e manteve associados a fatores sociodemográficos e comportamentais. Esses achados chamam a atenção para a necessidade de novas medidas regulatórias, a fim de reduzir o uso desse dispositivo.

This study aimed to estimate the prevalence of e-cigarette use and the association with predictors. This is a cross-sectional, analytical study with a probabilistic sample of university students enrolled in a University Center of Montes Claros, Minas Gerais, Brazil in the second half of 2022. The dependent variable referred to the use of electronic cigarettes. The independent variables referred to sociodemographic, labor and behavioral factors. The association between the variables investigated and the prevalence of EC use was verified by bivariate analysis and Poisson regression. A total of 730 university students were interviewed, with a mean age of 22.56 (±6.25). Of these, 21.8% used electronic cigarettes and after multivariate analysis, it remained associated with the outcome of not having a partner (PR= 3.31; CI95% 1.04-10.48), living with friends/alone (PR=1.53; CI95% 1.07-2.18), having a history of e-cigarette users in the residence (PR= 1.76; CI95%: 1.17- 1.89), alcohol consumption (PR= 3.07; CI95%: 1.72-5.49) and not practicing physical activity (PR= 3.37; IC95% 2.35-4.83). Knowing about electronic cigarettes was a protective factor (PR= 0.31 CI95% 0.20-0.46). There was a high prevalence of e-cigarette use, and it was associated with sociodemographic and behavioral factors. These findings draw attention to the need for new regulatory measures in order to reduce the use of this device.

High population levels lead Glycaspis brimblecombei (Hemiptera: Aphalaridae) to unrecorded feeding and oviposition behaviors on Eucalyptus urograndis plants / Altos níveis populacionais levam Glycaspis brimblecombei (Hemiptera: Aphalaridae) a diferentes comportamentos de alimentação e oviposição em plantas de Eucalyptus urograndis

The red gum lerp psyllid, Glycaspis brimblecombei Moore, 1964 (Hemiptera: Aphalaridae), an insect pest originating in Australia and which feeds only on Eucalyptus L'Hér. (Myrtales: Myrtaceae) plants, has spread to several countries. The populations of this insect commonly reach high populations on Eucalyptus plants since its entry into Brazil, and also indicated an unrecorded behavioral. The objectives of this study were to describe a peculiar adaptation in the feeding habit of G. brimblecombei and to register the new habit. The oviposition and feeding by G. brimblecombei, commonly, on the leaves of Eucalyptus, started to occur, also, on lignified twigs. This suggests a not yet recorded adaptation of this insect to reduce insect × plant intraspecific competition.

O psilídeo de concha, Glycaspis brimblecombei Moore, 1964 (Hemiptera: Aphalaridae), um inseto praga originário da Austrália e que se alimenta apenas de plantas de Eucalyptus L'Hér. (Myrtales: Myrtaceae), se espalhou por vários países. Esse inseto, geralmente, atinge grandes populações em plantas de Eucalyptus desde sua entrada no Brasil e, também, indicou um comportamento diferente. Os objetivos deste estudo foram descrever uma adaptação peculiar no hábito alimentar de G. brimblecombei e registrar o novo hábito. A oviposição e alimentação por G. brimblecombei, geralmente, nas folhas de Eucalyptus, passaram a ocorrer, também, em ramos lignificados. Isso sugere uma adaptação diferente desse inseto para reduzir a competição intraespecífica inseto × planta.

A Gestalt account of human behavior is supported by evidence from switching between single and dual actions.

The question of how behavior is represented in the mind lies at the core of psychology as the science of mind and behavior. While a long-standing research tradition has established two opposing fundamental views of perceptual representation, Structuralism and Gestalt psychology, we test both accounts with respect to action representation: Are multiple actions (characterizing human behavior in general) represented as the sum of their component actions (Structuralist view) or holistically (Gestalt view)? Using a single-/dual-response switch paradigm, we analyzed switches between dual ([A + B]) and single ([A], [B]) responses across different effector systems and revealed comparable performance in partial repetitions and full switches of behavioral requirements (e.g., in [A + B] → [A] vs. [B] → [A], or [A] → [A + B] vs. [B] → [A + B]), but only when the presence of dimensional overlap between responses allows for Gestalt formation. This evidence for a Gestalt view of behavior in our paradigm challenges some fundamental assumptions in current (tacitly Structuralist) action control theories (in particular the idea that all actions are represented compositionally with reference to their components), provides a novel explanatory angle for understanding complex, highly synchronized human behavior (e.g., dance), and delimitates the degree to which complex behavior can be analyzed in terms of its basic components.

Psychometric properties of the Reward Probability Index in a Colombian sample / Propiedades psicométricas del Índice de Probabilidad de Recompensa en una muestra Colombiana

Introduction: This study analysed the psychometric properties of the Reward Probability Index (RPI) in an online Colombian sample with 1129 participants. Method: To conduct a cross-validation study, the sample was randomly divided into two subsamples. An exploratory factor analysis was conducted with the first subsample yielding a two-factor structure. Then, the fit of this two-factor model was tested on the second subsample by conducting a confirmatory factor analysis. Results: This model obtained a good fit to the data and measurement invariance across gender was observed. The RPI also showed good internal consistency according to both Cronbach's alpha and McDonald's omega, scoring .88 in both cases. The RPI demonstrated convergent construct validity given its correlations with other related measures such as the Environmental Reward Observation Scale (r = .81), and the full version of the Behavioral Activation Scale for Depression (r = .71). Conclusions: The RPI showed good psychometric properties in this Colombian sample.

Introducción: Este artículo tuvo como objetivo analizar las propiedades psicométricas del Índice de Probabilidad de Recompensa (RPI) en una muestra colombiana en línea con 1129 participantes.

Evaluating the impact of continuing professional development courses on physician behavioral intention: a pre-post study with follow-up at six months.

BACKGROUND: Continuing professional development (CPD) for health professionals includes educational activities to maintain or improve skills. We evaluated the impact of a series of CPD courses by identifying factors influencing physicians' intention to adopt targeted behaviors and assessing self-reported behavior adoption six months later. METHODS: In this pre-post study, eligible participants attended at least one in-person course at the Fédération des Médecins Spécialistes du Québec annual meeting in November 2019. Before and afterwards, participants completed CPD-REACTION, a validated questionnaire based on Godin's integrated model for health professional behavior change that measures intention and psychosocial factors influencing intention. We used Wilcoxon signed-rank test to compare pre- and post-course intention scores and linear regression analyses to identify factors influencing intention. We also compared the post-course intention scores of participants reporting a behavior change six months later with the scores of those reporting no behavior change six months later. Qualitative data was collected only six months after courses and responses to open-ended questions were analyzed using the Theoretical Domains Framework. RESULTS: A total of 205/329 course attendees completed CPD-REACTION (response rate 62.3%). Among these participants, 158/329 (48%) completed the questionnaire before CPD courses, 129/329 (39.2%) only after courses and 47/329 (14.3%) at 6 months. Study population included 192 physicians of whom 78/192(40.6%) were female; 59/192(30.7%) were between 50 and 59 years old; and 72/192 (37.5%) were surgical specialist physicians. Mean intention scores before (n = 158) and after (n = 129) courses were 5.74(SD = 1.52) and 6.35(SD = 0.93) respectively. Differences in mean (DM) intention before and afterwards ranged from - 0.31(p = 0.17) to 2.25(p = 0.50). Multivariate analysis showed that beliefs about capabilities (ß = 0.15, p = 0.001), moral norm (ß = 0.75, p < 0.0001), and beliefs about consequences (ß = 0.11, p = 0.04) influenced post-course intention. Post-course intention was correlated with behavior six months later (DM = 0.63; p = 0.02). Qualitative analysis showed that facilitators to behavior adoption after six months were most often related to the TDF domains of beliefs about capabilities. Most frequent barriers to adoption related to lack of resources. CONCLUSIONS: Overall, scores for intention to adopt targeted behaviors increased after the courses. CPD providers could increase participants' intention by including interventions that emphasize beliefs about capabilities, moral norm and beliefs about consequences.

Enhanced Myocardial Adenylyl Cyclase Activity Alters Heart-Brain Communication.

BACKGROUND: The central nervous system's influence on cardiac function is well described; however, direct evidence for signaling from heart to brain remains sparse. Mice with cardiac-selective overexpression of adenylyl cyclase type 8 (TGAC8) display elevated heart rate/contractility and altered neuroautonomic surveillance. OBJECTIVES: In this study the authors tested whether elevated adenylyl cyclase type 8-dependent signaling at the cardiac cell level affects brain activity and behavior. METHODS: A telemetry system was used to record electrocardiogram (ECG) and electroencephalogram (EEG) in TGAC8 and wild-type mice simultaneously. The Granger causality statistical approach evaluated variations in the ECG/EEG relationship. Mouse behavior was assessed via elevated plus maze, open field, light-dark box, and fear conditioning tests. Transcriptomic and proteomic analyses were performed on brain tissue lysates. RESULTS: Behavioral testing revealed increased locomotor activity in TGAC8 that included a greater total distance traveled (+43%; P < 0.01), a higher average speed (+38%; P < 0.01), and a reduced freezing time (-45%; P < 0.01). Dual-lead telemetry recording confirmed a persistent heart rate elevation with a corresponding reduction in ECG-R-waves interval variability and revealed increased EEG-gamma activity in TGAC8 vs wild-type. Bioinformatic assessment of hippocampal tissue indicated upregulation of dopamine 5, gamma-aminobutyric acid A, and metabotropic glutamate 1/5 receptors, major players in gamma activity generation. Granger causality analyses of ECG and EEG recordings showed a marked increase in informational flow between the TGAC8 heart and brain. CONCLUSIONS: Perturbed signals arising from the heart cause changes in brain activity, altering mouse behavior. More specifically, the brain interprets augmented myocardial humoral/functional output as a "sustained exercise-like" situation and responds by activating central nervous system output controlling locomotion.

Misguided model of human behavior: Comment on C. H. Burt: "Challenging the utility of polygenic scores for social science ".

This commentary emphasizes two problem areas mentioned by Burt. First, that within-family designs do not eradicate stratification confounds. Second, that the linear/additive model of genetic causes of form and variation is not supported by recent progress in molecular biology. It concludes with an appeal for a (biologically and psychologically) more realistic model of such causes.

[A review of studies on visual behavior analysis aided diagnosis of autism spectrum disorders].

Autism spectrum disorder (ASD) is a neurodevelopmental disorder characterized by deficits in social communication and repetitive behaviors. With the rapid development of computer vision, visual behavior analysis aided diagnosis of ASD has got more and more attention. This paper reviews the research on visual behavior analysis aided diagnosis of ASD. First, the core symptoms and clinical diagnostic criteria of ASD are introduced briefly. Secondly, according to clinical diagnostic criteria, the interaction scenes are classified and introduced. Then, the existing relevant datasets are discussed. Finally, we analyze and compare the advantages and disadvantages of visual behavior analysis aided diagnosis methods for ASD in different interactive scenarios. The challenges in this research field are summarized and the prospects of related research are presented to promote the clinical application of visual behavior analysis in ASD diagnosis.

Bridge-building between communities: Imagining the future of biomedical autism research.

A paradigm shift in research culture is required to ease perceived tensions between autistic people and the biomedical research community. As a group of autistic and non-autistic scientists and stakeholders, we contend that through participatory research, we can reject a deficit-based conceptualization of autism while building a shared vision for a neurodiversity-affirmative biomedical research paradigm.
