Impact on healthcare costs of adding telemedicine to a multidisciplinary disease management program for heart failure: a sub-analysis of the iCOR trial

Abstract Background Impact of telemedicine on heart failure outcomes has shown conflicting results. Little is known about the effect of these programs on mid-term healthcare costs. Purpose To evaluate the cost-efficacy of a comprehensive telemonitoring program within the vulnerable post-discharge period after an acute heart failure admission. Methods The insuficiència cardiaca Optimizació Remota (iCOR) trial was a single-centre, randomized, open-label study designed to evaluate the efficacy of the addition of telemonitoring and teleintervention to a specialized multidisciplinary nurse-led heart failure (HF) program. Adult patients with a recent hospital admission for acute HF and an acceptable social support and cognitive ability were recruited. This sub-analysis evaluates the effect of telemedicine on mid-term healthcare costs, including clinical events, drugs and devices, technology purchase and maintenance, outpatient care, days of hospitalization, procedures and complementary tests. t-test via bootstrap estimation is used to compare differences between the telemedicine (TM) and the usual care (UC) groups. Results 81 patients were assigned to the TM group and 97 patients to the UC group. Mean age was 74 years, more than 50% had HF with preserved ejection fraction and 25% were frail. Baseline characteristics were well-balanced between groups. Among the TM subgroup, adherence was very high (< 1% of missed biometric daily transmissions). During 6 months of follow-up, mean total healthcare cost per patient was 7949 euros (€) in the UC cohort and 4383 € in the TM cohort (relative risk reduction [RRR] of 45%; between-group differences 3546 €, 95% confidence interval 627-6464 €, bootstrap achieved significance level 0.022). This result was consistent across several subgroups (age, sex, frailty, left ventricular ejection fraction, educational level) and mainly driven by a 63% RRR in costs of hospitalization (which accounted for two-thirds of the total costs) in the TM cohort. 20 patients required HF admissions in the TM group, compared to 51 patients in the TM group (p < 0.001). This was associated with a 59% RRR in the need for diagnostic procedures. Total number of days of hospitalization per patient decreased from 12.2 in the UC group to 4.2 days in the TM group (p = 0.003), impelled by a reduction in HF and cardiovascular days of hospital stay. On the contrary, ambulatory care costs increase two-fold in the TM group compared to UC group. Nevertheless, these costs only accounted for a 19% of the total costs. Cost of devices needed to implement TM supposed 698 € per patient. Use of TM was associated with a 355 € increase in the cost of ambulatory neurohormonal treatment for HF. Conclusions TM implementation during the vulnerable phase after an acute HF admission was associated to a 45% RR reduction in mean total healthcare cost per patient. This result was driven by an almost two-thirds decrease in costs of hospitalization.UC and TM total healthcare costs

How Does Understanding of Social Situations and Other's Intention Contribute to Idiom and Irony Comprehension in Autism Spectrum Disorder?

Background/Objectives: Figurative language is a central tool for enriching spoken and written languages, and it is important for building social relationships. Difficulties in figurative language understanding may impair social adjustment. Some studies have found more gaps in the understanding of irony and idioms among children with autism spectrum disorder (ASD) compared to those of their peers with typical development (TD). To date, no studies have examined the relationship between the ability to understand social situations (as a separate ability) and the ability to understand irony and idioms. The present study examined the roles of theory of mind (ToM) and social situation understanding in the comprehension of idioms and ironic criticism. Methods: The current study included 58 participants aged 8-11, including 28 children with high-functioning ASD and 30 children with TD matched by age, gender, and nonverbal intelligence. All the participants completed a ToM questionnaire that assesses their understanding of others' intentions, as well as a questionnaire pertaining to their comprehension of social situations, ironic criticism, and idioms. Results: TD children outperformed the autistic children in idiom and irony understanding, as well as in ToM and social situation understanding. Understanding social situations and ToM contributed to idiom and irony understanding, with ToM ability uniquely contributing to irony (but not to idiom) understanding. Path analysis revealed that social cognitive abilities mediated the link between group affiliation and vocabulary, affecting figurative language comprehension. Conclusions: The present study demonstrates that social cognition skills influence the ability to understand ironic criticism and idioms, mediating the association between vocabulary and figurative language comprehension.

Social cognition in adults with neurofibromatosis type 1.

Adult patients with the genetic disease neurofibromatosis type 1 (NF1) frequently report social difficulties. To date, however, only two studies have explored whether these difficulties are caused by social cognition deficits, and these yielded contradictory data. The aim of the present study was to exhaustively assess social cognition abilities (emotion, theory of mind, moral reasoning, and social information processing) in adults with NF1, compared with a control group, and to explore links between social cognition and disease characteristics (mode of inheritance, severity, and visibility). We administered a social cognition battery to 20 adults with NF1 (mean age = 26.5 years, SD = 7.4) and 20 healthy adults matched for sociodemographic variables. Patients scored significantly lower than controls on emotion, theory of mind, moral reasoning, and social information processing tasks. No effects of disease characteristics were found. These results appear to confirm that adults with NF1 have a social cognition weaknesses that could explain, at least in part, their social difficulties, although social abilities are not all impaired to the same extent. Regarding the impact of the disease characteristics, the patient sample seemed slightly insufficient for the power analyses performed. Thus, this exploratory study should form the basis of further research, with the objective of replicating these results with larger and more appropriately matched samples.

Behavioral observation and assessment protocol for language and social-emotional development study in children aged 0–6: the Chinese baby connectome project

BackgroundThe global rise in developmental delays underscores the critical need for a thorough understanding and timely interventions during early childhood. Addressing this issue, the Chinese Baby Connectome Project (CBCP)’s behavior branch is dedicated to examining language acquisition, social-emotional development, and environmental factors affecting Chinese children. The research framework is built around three primary objectives: developing a 0–6 Child Development Assessment Toolkit, implementing an Intelligent Coding System, and investigating environmental influence.MethodsUtilizing an accelerated longitudinal design, the CBCP aims to enlist a minimum of 1000 typically developing Chinese children aged 0–6. The data collected in this branch constitutes parental questionnaires, behavioral assessments, and observational experiments to capture their developmental milestones and environmental influences holistically. The parental questionnaires will gauge children’s developmental levels in language and social-emotional domains, alongside parental mental well-being, life events, parenting stress, parenting styles, and family relationships. Behavioral assessments will involve neurofunctional developmental evaluations using tools such as the Griffiths Development Scales and Wechsler Preschool and Primary Scale of Intelligence. Additionally, the assessments will encompass measuring children’s executive functions (e.g., Head-Toe-Knee-Shoulder), social cognitive abilities (e.g., theory of mind), and language development (e.g., Early Chinese Vocabulary Test). A series of behavior observation. experiments will be conducted targeting children of different age groups, focusing primarily on aspects such as behavioral inhibition, compliance, self-control, and social-emotional regulation. To achieve the objectives, established international questionnaires will be adapted to suit local contexts and devise customized metrics for evaluating children’s language and social-emotional development; deep learning algorithms will be developed in the observational experiments to enable automated behavioral analysis; and statistical models will be built to factor in various environmental variables to comprehensively outline developmental trajectories and relationships.DiscussionThis study’s integration of diverse assessments and AI technology will offer a detailed analysis of early childhood development in China, particularly in the realms of language acquisition and social-emotional skills. The development of a comprehensive assessment toolkit and coding system will enhance our ability to understand and support the development of Chinese children, contributing significantly to the field of early childhood development research.Trial registrationThis study was registered with clinicaltrials.gov NCT05040542 on September 10, 2021.

Evidence for the communicative function of human-directed gazing in 6- to 7-week-old dog puppies

In human infants, the ability to show gaze alternations between an object of interest and another individual is considered fundamental to the development of complex social-cognitive abilities. Here we show that well-socialised dog puppies show gaze alternations in two contexts at an early age, 6–7 weeks. Thus, 69.4% of puppies in a novel object test and 45.59% of puppies during an unsolvable task alternated their gaze at least once between a person’s face and the object. In both contexts, the frequency of gaze alternations was positively correlated with the duration of whimpering, supporting the communicative nature of puppies’ gazing. Furthermore, the number of gaze alternations in the two contexts was correlated, indicating an underlying propensity for gazing at humans despite likely different motivations in the two contexts. Similar to humans, and unlike great apes or wolves, domestic dogs show gaze alternations from an early age if they are well-socialised. They appear to have a genetic preparedness to communicate with humans via gaze alternations early in ontogeny, but they may need close contact with humans for this ability to emerge, highlighting the interactive effects of domestication and environmental factors on behavioural development in dogs.

Mentalization-based interventions in schools for enhancing socio-emotional competencies and positive behaviour: a systematic review.

Mentalization-based interventions (MBIs) have been increasingly applied in school settings to support the social-emotional development and mental health of children and adolescents. This systematic review aimed to synthesize the evidence on the effectiveness of MBIs implemented in educational contexts for students aged 6-18 years. A comprehensive search was conducted in PsychInfo, MEDLINE, EMBASE, Web of Science, and ERIC databases from inception to October 2023. The search strategy combined terms related to mentalization, school-based interventions, and the target age group. The review protocol was registered with PROSPERO (CRD42022302757). Inclusion criteria included peer-reviewed publications in English, studies published between 1980 and 2023, interventions based on mentalization principles, and a primary focus on children aged 6 to 18 years. Exclusion criteria involved non-mentalization based interventions and research outside the 6-18 age range. The risk of bias was assessed using the Quality Assessment Tools from the National Institutes of Health (NIH). Data were synthesized narratively due to the heterogeneity of study designs and outcomes. Of the 5,250 articles screened, 21 studies met the inclusion criteria, comprising over 7,500 participants. The reviewed interventions targeted various aspects of mentalizing, such as emotion-understanding, empathy, perspective-taking, and Theory of Mind. Significant improvements were found in social-cognitive abilities, emotion regulation, and mental health outcomes, including reductions in disruptive behaviours. Interventions that combined mentalizing training for both students and teachers showed promising results. However, the long-term sustainability of these benefits remains unclear. Limitations of the reviewed studies include the lack of control groups, small sample sizes, and variations in outcome measures. The findings highlight the potential of MBIs as a promising approach to fostering socio-emotional competence, positive behaviour, and well-being in school-aged children. Future research should aim to establish the active components and optimal delivery of these interventions through well-designed randomized controlled trials with larger, more diverse samples and extended follow-up periods. The integration of MBIs within educational systems holds promise for promoting resilience and positive mental health outcomes in young people. Embedding MBIs within school curriculums and evaluating cost-effectiveness are important next steps to guide widespread implementation.

The effect of social isolation on the cognitive ability of the oldest old in Chinese nursing homes in post-COVID-19: a moderated chain mediation model.

Both pre-or post-COVID-19, older adults residing in nursing homes are at significant risk for social isolation, which is negatively associated with cognitive ability. Currently, the elderly aged 80 years and older are the fastest-growing age group globally. The extent of social isolation within this group post-COVID-19 and its impact on cognitive abilities remain inadequately explored. This research aimed to evaluate the prevalence of social isolation among the oldest old in Chinese nursing homes post-COVID-19 and to investigate the mediating and moderating roles of basic activities of daily living (BADL), depression, and subjective socioeconomic status in the relationship between social isolation and cognitive ability. This cross-sectional study included 453 participants aged 80 years and older from 11 nursing homes in Ningbo, Zhejiang Province, China. Social isolation was assessed using the Lubben Social Network Scale-6 (LSNS-6), cognitive ability using the Mini-Mental State Examination (MMSE), BADL using the Barthel Index (BI), and depression using the Patient Health Questionnaire-9 items (PHQ-9). Mediation and moderation effects were statistically analyzed using SPSS 23.0 and PROCESS 3.5. The mean age of the study sample was 87.1 ± 3.8 years, among whom 60.3% (n = 273) were female, and 56.1% experienced social isolation, with 41.1% and 63.1% being isolated from family and friends, respectively. Social isolation indirectly affected cognitive ability through BADL and depression, respectively, and through the chain mediation effect of BADL and depression. Subjective socioeconomic status moderated the relationships between social isolation and BADL and between social isolation and depression. However, no moderating effect of subjective socioeconomic status was found between social isolation and cognitive ability. This study deepens our understanding of the current state of social isolation and its mechanisms of action in the oldest old post-COVID-19 and provides a new basis for future public health policy development and related research.

Social face processing in chronic severe traumatic brain injury: Altered decoding of emotions and mental states but preserved gaze cueing of attention

The processing of social information transmitted by facial stimuli is altered in individuals with traumatic brain injury (TBI). This study investigated whether these alterations also affect the mechanisms underlying the orienting of visual attention in response to eye-gaze signals. TBI patients and a control group of healthy individuals matched on relevant criteria completed a spatial cueing task. In this task, a lateral visual target was presented along with a task-irrelevant face, with the gaze averted to the left or right. Arrows pointing towards the left or right were also used as non-social control stimuli. Social cognition abilities were further investigated through tests based on decoding emotional expressions and mental states conveyed by facial stimuli. The decoding of emotions and mental states was worse in the TBI group than in the control group. However, both groups demonstrated reliable and comparable orienting of attention to both eye-gaze and arrow stimuli. Despite impairments in certain aspects of social face processing among TBI patients, gaze cueing of attention appears to be preserved in this neuropsychological population.

Probability errors in children's judgements about the likelihood of social characteristics.

The studies reported here investigated mechanisms underlying children's tendency to commit the conjunction fallacy (judging that a conjunction of two events is more likely than one of the events in isolation) when judging people's characteristics. Study 1 investigated these errors in 4- and 5-year-olds (N = 58) using a newly developed social judgement task in which children judged whether a conjunction or one of its elements would apply to a protagonist. Children made conjunction fallacy errors at chance level. Study 2 (N = 71) replicated these findings using an adapted version of the task, in which children separately judged the likelihood of the conjunction and each of its events. Study 3 investigated age-related changes in conjunction fallacy errors in a sample of 148 children aged 4 to 11 years old and 130 adults. This study also investigated how providing background information on the protagonist influenced error rate. Unlike younger children, 10- and 11-year-olds committed the conjunction fallacy at chance level in the absence of background information, but providing information consistent with the likely component of the conjunction significantly increased their error rate. Adults' error rate also significantly increased after the introduction of background information. Across all three studies, conjunction fallacy errors were unrelated to cognitive and social-cognitive abilities, such as verbal ability, theory of mind, and inhibitory control (Studies 1 and 2), and prejudice and hindsight bias (Study 3). These findings suggest that it is only in the second decade of life that children use social information to inform their judgements about people and that social decision-making errors are not determined by core aspects of cognitive and social-cognitive development.

NAO robot promoting sensorimotor synchronization in high-functioning autism spectrum disorder children

Objectives Sensorimotor synchronization (SMS) refers to an individual’s motor rhythm is temporally coordinated with a predictable external rhythm. Autism spectrum disorder (ASD) children have weakened SMS performance than typically developing (TD) children, which may affect their relationship with peers and caregivers, and social cognition abilities. Synchronization referent (e.g. an adult or a non-social beat) and the length of inter-stimulus interval (ISI) would influence SMS performance. Methods In this study, we adapted a tapping task to investigate the SMS ability in twenty-one 5–8-year-old high-functioning ASD and twenty-one age-, gender- and IQ-matched TD children. Children were asked to tap on a computer keyboard with videos of a woman or a robot tapping with one finger. We compared the synchronization performance of the two groups when they synchronized with different partners (an adult or an NAO robot) and under different ISIs (800 ms or 1500 ms). The relationships with participants’ autistic traits (Social Responsiveness Scale (SRS-2) and Autism Spectrum Quotient), and cognitive ability (IQ) were also examined. Results We found that ASD children had an overall attenuated synchronizing accuracy and stability than TD children only when ISI was longer than one second. Both groups performed better when synchronized with the NAO robot than the adult partner. The synchronization performance was correlated with the cognitive ability of ASD children when ISI was 1500 ms. Conclusions Results show that tapping with the robot could improve the SMS performance of ASD children since it promoted a higher motivation level. ASD children have an attenuated SMS ability, which may be caused by abnormal temporal perceptions when ISI is longer than one second, while their SMS ability may be intact in sub-second ISIs.

A Systematic Review of the Positive Effects of Pets on Child Development

It is necessary for parents to consider the essential child development after the birth of their kids, includeing various aspects such as social skills, stress regulation and cognitive abilities. This review focuses on the effects of pets on children in general families in the process of child development by evaluating and investigating relevant case studies, and children with special conditions including mental illness or psychological problems are not considered in this analysis for the time being. Overall, this review shows that pets have a significant positive effect on social interactions, intellectual development, concentration, stress reduction etc. in child development.. Besides, pets can help to build a loving and stable family atmosphere which provides a conducive environment for child development, and improves the ability children interact with their parents. Although some literatures indicates that negative impacts on children development can occur when children stay with pets, overall, the positive boosts to children's development far outweigh the negatives.

Social Cognition in Parkinson's Disease after Focused Ultrasound Subthalamotomy: A Controlled Study.

Social cognition (SC) encompasses a set of cognitive functions that enable individuals to understand and respond appropriately to social interactions. Although focused ultrasound subthalamotomy (FUS-STN) effectively treats Parkinson's disease (PD) clinical motor features, its impact and safety on cognitive-behavioral interactions/interpersonal awareness are unknown. This study investigated the effects of unilateral FUS-STN on facial emotion recognition (FER) and affective and cognitive theory of mind (ToM) in PD patients from a randomized sham-controlled trial (NCT03454425). Subjects performed SC evaluation before and 4 months after the procedure while still under blind assessment conditions. The SC assessment included the Karolinska Directed Emotional Faces task for FER, the Reading the Mind in the Eyes (RME) test for affective ToM, and The Theory of Mind Picture Stories Task (ToM PST) (order, questions, and total score) for cognitive ToM. The active treatment group showed anecdotal-to-moderate evidence of no worsening in SC after FUS-STN. Anecdotal evidence for an improvement was recognized in the SC score changes, from baseline to post-treatment, for the active treatment group compared with sham for the RME, ToM PST order, ToM PST total, FER total, and recognition of fear, disgust, and anger. This study provides the first evidence that unilateral FUS-STN does not impair social cognitive abilities, indicating that it can be considered a safe treatment approach for this domain in PD patients. Furthermore, the results suggest FUS-STN may even lead to some improvement in social cognitive outcomes, which should be considered as a preliminary finding requiring further investigation with larger samples sizes. © 2024 International Parkinson and Movement Disorder Society.

On the Relationship Between Alexithymia and Social Cognition: A Systematic Review.

This systematic review summarises the studies that have investigated the relationship between dimensions of social cognition (i.e., Theory of Mind - ToM, emotion recognition, and empathy) and alexithymia in the general adult non-clinical population. PubMed, PsycINFO, and Scopus databases were screened, using the following strings: ("alexithymi*") AND ("theory of mind" OR "ToM"); ("alexithymi*") AND ("empath*"); ("alexithymi*") AND ("emotion recognition"); ("alexithymi*") AND ("social cognition"). A total of 117 studies met the inclusion criteria and were included in this review. The total number of participants included in the reviewed studies was 40,231. Mixed results were found for alexithymia and ToM, while the relationship between emotion recognition or empathy and alexithymia was more homogeneous. Alexithymia was found to be significantly associated with both a reduced ability to recognise emotions and empathy. These results support the existence of significant relationships between alexithymia and altered social cognitive abilities. Future research is needed to confirm the present findings and further elucidate the complex relationship between these processes. Suggestions are made on how to overcome some of the theoretical and methodological problems in the literature.

Verbal Perceptual Prompts Facilitate Children's Sensitivity to False Beliefs.

False belief understanding is always regarded as a milestone of Theory of Mind (ToM), which is an important aspect of social intelligence. Recently, some researchers have suggested the existence of two ToM systems in individuals: one that explicitly guides false belief understanding and another that implicitly directs sensitivity to false beliefs. However, studies on sensitivity to false beliefs have encountered challenges with replicability, and the factors influencing the manifestation of sensitivity to false beliefs remain to be explored. Based on the anticipatory looking task, we investigated whether verbal perceptual prompts could improve children's performance of sensitivity to false beliefs. Fifty-eight children aged 5 to 6 were randomly assigned tasks with or without verbal perceptual prompts, involving verbal descriptions and explanations of the protagonist's perceptual state. The findings showed that verbal perceptual prompts could slightly reduce children's propensity to look at the actual location of the object in false belief situations and increase the likelihood of exhibiting accurate anticipatory looking patterns across false belief and true belief situations. The results suggest that children's sensitivity to false beliefs may be situation-dependent, yet further investigation is needed to determine which situational factors can most effectively trigger robust sensitivity to false beliefs in children. The results enlighten educational practice, indicating that introducing cues in social environments that convey insights into others' mental states, akin to the use of learning scaffolding, is advantageous for the development of children's social cognitive abilities.

Social perception of animacy: Preferential attentional orienting to animals links with autistic traits

Animate cues enjoy priority in attentional processes as they carry survival-relevant information and herald social interaction. Whether and in what way such an attention effect is associated with more general aspects of social cognition remains largely unexplored. Here we investigated whether the attentional preference for animals varies with observers' autistic traits — an indicator of autism-like characteristics in general populations related to one's social cognitive abilities. Using the dot-probe paradigm, we found that animal cues can rapidly and persistently recruit preferential attention over inanimate ones in observers with relatively low, but not high, autistic traits, as measured by Autism-Spectrum Quotient (AQ). Moreover, individual AQ scores were negatively correlated with the attentional bias toward animals, especially at the early orienting stage. These results were not simply due to low-level visual factors, as inverted or phase-scrambled pictures did not yield a similar pattern. Our findings demonstrate an automatic and enduring attentional bias beneficial to both rapid detection and continuous monitoring of animals and reveal its link with autistic traits, highlighting the critical role of animacy perception in the architecture of social cognition.

Variation in gaze following across the life span: A process-level perspective.

Following eye gaze is fundamental for many social-cognitive abilities, for example, when judging what another agent can or cannot know. While the emergence of gaze following has been thoroughly studied on a group level, we know little about (a) the developmental trajectory beyond infancy and (b) the sources of individual differences. In Study 1, we examined gaze following across the lifespan (N=478 3- to 19-year-olds from Leipzig, Germany; and N=240 20- to 80-year-old international, remotely tested adults). We found a steep performance improvement during preschool years, in which children became more precise in locating the attentional focus of an agent. Precision levels then stayed comparably stable throughout adulthood with a minor decline toward old age. In Study 2, we formalized the process of gaze following in a computational cognitive model that allowed us to conceptualize individual differences in a psychologically meaningful way (N=60 3- to 5-year-olds, 50 adults). According to our model, participants estimate pupil angles with varying levels of precision based on observing the pupil location within the agent's eyes. In Study 3, we empirically tested how gaze following relates to vector following in non-social settings and perspective-taking abilities (N=102 4- to 5-year-olds). We found that gaze following is associated with both of these abilities but less so with other Theory of Mind tasks. This work illustrates how the combination of reliable measurement instruments and formal theoretical models allows us to explore the in(ter)dependence of core social-cognitive processes in greater detail. RESEARCH HIGHLIGHTS: Gaze following develops beyond infancy. The highest precision levels in localizing attentional foci are reached in young adulthood with a slight decrease towards old age. We present a computational model that describes gaze following as a process of estimating pupil angles and the corresponding gaze vectors. The model explains individual differences and recovers signature patterns in the data. To estimate the relation between gaze- and vector following, we designed a non-social vector following task. We found substantial correlations between gaze following and vector following, as well as Level 2 perspective-taking. Other Theory of Mind tasks did not correlate.

Efficacy of a Remote Play-Based Intervention for Children With Prader-Willi Syndrome.

The current study examines the efficacy of an 8-week pretend play intervention targeting social-cognitive abilities in children with Prader-Willi syndrome (PWS), ages 6-9. PWS is a rare disorder associated with various social, emotional, and cognitive challenges linked to pretend play impairments, and for which interventions are sparse. Nineteen children were quasi-randomized to receive the intervention or be part of a waitlist control group. Participants who received the intervention (n = 10) demonstrated significant improvements in various components of pretend play, most notably in organization of play, which may generalize to broader social-cognitive gains. These findings provide evidence of the intervention's efficacy in enhancing pretend play skills and related social-cognitive abilities during this critical period of development for children with PWS.

From One's Heart to the Mind of Others: A Study in School-Aged Children.

Studies have shown a significant association between effective parasympathetic modulation of the heart and processes linked to social cognition. Particularly, Quintana and colleagues documented a relation between vagally-mediated heart rate variability (vmHRV) and performance on a theory of mind (ToM) task, namely, the Reading the Mind in the Eyes Test (RMET), in a sample of university students. The purpose of the present study was to test whether such result would extend to a sample of school-aged children (7-9 years old) using the child version of the RMET. In addition, the Eyes Test Revised was administered as it is more suitable to evaluate ToM during childhood. Results supported the positive association between vmHRV and ToM abilities, replicating and extending previous results obtained in young adults. The current study adds to the existing literature pointing to HRV as a putative biomarker of social cognition abilities.

The Social Cognition Ability Evaluation of LLMs: A Dynamic Gamified Assessment and Hierarchical Social Learning Measurement Approach

Large Language Model(LLM) has shown amazing abilities in reasoning tasks, theory of mind(ToM) has been tested in many studies as part of reasoning tasks, and social learning, which is closely related to theory of mind, are still lack of investigation. However, the test methods and materials make the test results unconvincing. We propose a dynamic gamified assessment(DGA) and hierarchical social learning measurement to test ToM and social learning capacities in LLMs. The test for ToM consists of five parts. First, we extract ToM tasks from ToM experiments and then design game rules to satisfy the ToM task requirement. After that, we design ToM questions to match the game’s rules and use these to generate test materials. Finally, we go through the above steps to test the model. To assess the social learning ability, we introduce a novel set of social rules (three in total). Experiment results demonstrate that, except GPT-4, LLMs performed poorly on the ToM test but showed a certain level of social learning ability in social learning measurement.

Alterations in resting-state gamma-activity is adults with autism spectrum disorder: A High-Density EEG study

Autism spectrum disorder (ASD) is a neurodevelopmental disorder with a wide range of symptoms that include deficits in social cognition and difficulties with social interactions. Neural oscillations in the EEG gamma band have been proposed as an important candidate neurobiological marker of higher order cognitive processes and social interactions. We investigated resting-state gamma-activity of patients with ASD (n=23) in order to delineate alterations as compared to typically developing (TD) subjects (n=24). EEG absolute power was examined in the gamma (30-100Hz) frequency band. We found significantly reduced spectral power across the entire gamma range in the ASD group. The decrease was most pronounced over the inferior-frontal and temporo-parietal junction areas. We also found a significant decrease in gamma-activity over the dorsolateral prefrontal cortex, especially in the left side. Since these brain areas have been associated with social functioning, the reduced gamma-activity in ASD may represent a cortical dysfunction that could underlie a diminished capacity to interpret socially important information, thereby interfering with social functioning. The alterations we found may lend support for an improved diagnosis. Furthermore, they can lead to focused therapies, by targeting the dysfunctional brain activity to improve social cognitive and interaction abilities that are compromised in ASD.
