Embodied language and early motor restriction: evidence from children with obstetric brachial plexus palsy and arthrogryposis
2026 · ARTICLE · en
Embodied and embedded cognition (EEC) theory proposes that language and cognitive development emerge from bodily interactions with the environment, yet empirical tests of this claim in clinical developmental populations remain rare. This mini-review synthesizes behavioral, electrophysiological, and structural neuroimaging evidence from children with serious early motor disorders—obstetric brachial plexus palsy and arthrogryposis multiplex congenita—which restrict upper limb movement from birth or before, providing a unique opportunity to test EEC predictions in a motor-restricted population. The results reveal a gradient of cognitive and linguistic alterations: from domain-specific deficits in action-verb semantics and verbal fluency, to broader impairments in memory, categorical reasoning, and naturalistic neural processing. Based on these multimodal findings, we propose that early sensorimotor restriction does not only affect motor systems but may shape the neurodevelopmental trajectory of language and other distributed cognitive architectures through mechanisms of embodied grounding.
Comparing experience- and description-based economic preferences across 11 countries
2024 · ARTICLE · en
Recent evidence indicates that reward value encoding in humans is highly context dependent, leading to suboptimal decisions in some cases, but whether this computational constraint on valuation is a shared feature of human cognition remains unknown. Here we studied the behaviour of n = 561 individuals from 11 countries of markedly different socioeconomic and cultural makeup. Our findings show that context sensitivity was present in all 11 countries. Suboptimal decisions generated by context manipulation were not explained by risk aversion, as estimated through a separate description-based choice task (that is, lotteries) consisting of matched decision offers. Conversely, risk aversion significantly differed across countries. Overall, our findings suggest that context-dependent reward value encoding is a feature of human cognition that remains consistently present across different countries, as opposed to description-based decision-making, which is more permeable to cultural factors.
Impact of audio and video narratives describing financial successes and failures on risk-taking in the Balloon Analogue Risk Task
2024 · ARTICLE · en
Narratives can influence risk-taking by shaping perceptions and emotions. In the present study we used first-person audio and video narratives describing either financial successes, failures, or neutral events devoid of any risk references in order to investigate how these types of stimuli affect risk-taking performance in the Balloon Analogue Risk Task (BART). Audio narratives of different types did not significantly alter risk-taking in the BART. However, videos depicting neutral narratives and narratives about financial successes surprisingly had risk-demoting influence compared to videos about financial failures, indexed by the percentage of popped balloons. The underlying reason for this finding remains to be understood. Additionally, gender differences emerged by the adjusted pumps measure in interaction with stimuli condition. Specifically, female participants displayed riskier tendencies after audio narratives, and conversely, video narratives led to a slight increase in risk-taking among male participants. These results emphasize the significant role of stimuli modality and indexing measures in risk-related studies.
Neurostructural Consequences of Obstetric Brachial Plexus Palsy in Childhood
2024 · ARTICLE · en
Obstetric brachial plexus palsy (OBPP) is a condition impairing limb function caused by birth injury. In 20 to 30% of cases, severe OBPP can cause life constraints in feeding, grooming, and clothing tasks. The present study, using voxel- and surface-based morphometry (VBM and SBM), examined the brain structure of pediatric OBPP patients to better understand the effects of this peripheral motor deficit on early brain development.
Attenuation of Evoked Responses Elicited by Hand Action Words During EEG Mismatch Negativity Recordings in Children with Motor Impairments
2024 · CHAPTER · en
Arthrogryposis multiplex congenita (AMC) and obstetric brachial plexus palsy (OBPP) are motor disorders that result in highly limited mobility of the extremities. Previously, we showed that in response to auditory speech stimuli, AMC/OBPP children exhibited altered MMN responses compared to healthy controls. Moreover, these alterations were semantically specific. Given that the distribution of ERPs evoked by linguistic stimuli is known to be non-stationary over time, we hypothesized that altered processing of action words related to the impaired limb observed in AMC/OBPP children might result not from constantly decreased deviant ERP amplitudes in response to the hand-related action words, but rather from altered dynamics of the amplitude shift in these responses throughout the experimental session. To track this effect, we split each of the MMN paradigm EEG recordings into three consecutive non- overlapping fractions with identical amounts of epochs locked to standard and deviant stimuli. We used two oddball series: (1) the hand condition with hand action-related imperative verb as deviant stimulus and matched pseudoword as standard stimulus; (2) the control condition with a meaningless pseudoword that sounded like an imperative verb as deviant stimuli and a matched pseudoword with no phonological similarity to any imperative verb as standard stimulus. All stimuli were disyllabic. The first syllables varied across the stimuli series but remained identical within them, whereas the onset of the second syllabus defined the disambiguation time. 27 AMC/OBPP patients (11 females; 8.63±3.35 y.o.) and 32 control children (16 females; 10.03±3.16 y.o.) participated in the study. Remarkably, the topographical pattern of the difference in deviant ERPs between the first and the last third recording fractions was similar to the typical spatial distribution of the MMN. We believe that this similarity might reflect some kind of “standardization” of the deviant stimulus that occurs throughout the experimental session as a result of the response attenuation. Specifically, deviant ERP amplitudes in the last fraction of the recording were decreased compared to the beginning of the recording in the hand condition in AMC/OBPP patients (frontal cluster of electrodes at 80-120 ms). No effect was observed either in the control pseudoword condition in AMC/OBPP patients or in both conditions in the control group, highlighting the semantical specificity of the effect. Overall, our findings suggest that altered processing of hand action-related verbs in AMC/OBPP children might result from altered dynamics of the MMN-response attenuation.
Altered evoked responses for motor-related words in children with upper limb motor impairments
2023 · ARTICLE · en
Objective Obstetric brachial plexus palsy (OBPP) and amyoplasia, the classical type of arthrogryposis multiplex congenita, manifest themselves as highly limited mobility of the upper limb. At the same time, according to the embodiment cognition theories, the motor impairments might lead to the alteration of cognitive functions in OBPP/amyoplasia patients. In the current study, we examined whether OBPP/amyoplasia children exhibit altered processing of motor-related verbs. Methods We conducted a case-control study using clinical population and control children. Oddball series were used to elicit mismatch negativity (MMN) EEG responses. The series consisted of limb-related verbs (deviant stimuli) and matched pseudowords (standard stimuli). 27 patients and 32 control children were included in the analysis. Results We showed that MMN waveforms differed between OBPP/amyoplasia children and their control peers in the frontal and temporal electrodes when the stimuli contained hand-related verbs. In particular, the MMN peak latency in the OBPP/amyoplasia children was significantly delayed as compared with the healthy controls. At the same time, neither series with leg-related verbs nor series of pseudowords resulted in statistically significant differences. Conclusions Our findings suggest altered processing of hand-related verbs in OBPP/amyoplasia children with hand-related disabilities. Significance Our results contribute to the growing evidence in support of the theory of embodied cognition, which proposes that various domains of cognition are shaped by bodily interactions with the environment.
Similar Cognitive Skill Impairment in Children with Upper Limb Motor Disorders Due to Arthrogryposis Multiplex Congenita and Obstetrical Brachial Plexus Palsy
2023 · ARTICLE · en
Arthrogryposis multiplex congenita (AMC) and obstetrical brachial plexus palsy (OBPP) are motor disorders with similar symptoms (contractures and the disturbance of upper limb function). Both conditions present as flaccid paresis but differ from each other in the pathogenesis: AMC is a congenital condition, while OBPP results from trauma during childbirth. Despite this difference, these diseases are identical in terms of their manifestations and treatment programmes. We compared the cognitive skills of children with AMC and OBPP diagnoses with those of healthy children; we also compared the motor skills of impaired children with those of healthy ones. The patients in both groups significantly differed from the healthy children with regard to psychological parameters, such as ‘visual memory capacity’ and ‘thinking’. Moreover, the two groups with children with AMC and OBPP significantly differed from each other in motor skill parameters, such as ‘delayed motor development’, ‘general motor development’, and the ‘level of paresis’. Upper limb motor function in the OBPP children was less impaired compared to that of the AMC children. However, we did not find any significant differences in cognitive deficits between the AMC children and the OBPP children. This may indicate that motor impairment is more significant than the underlying cause for the development of cognitive impairment; however, the factors causing this phenomenon require further study (e.g., social environment, treatment, and rehabilitation programme).
Exploring structural brain changes in children with neonatal brachial plexus palsy: a voxel-based morphometry analysis
2023 · ARTICLE · en
BACKGROUND: Obstetric brachial plexus palsy (OBPP) is paralysis of the upper limb resulting from nerve injury during vaginal delivery. Although current treatment approaches frequently lead to complete reinnervation of the limb, some patients show long-term motor deficits. These impairments may result from upper limb disuse that causes structural brain changes. AIM: This study aimed to compare deep gray matter volumes between children with OBPP and healthy controls. METHODS: We analyzed the structural magnetic resonance imaging results of 46 children with OBPP (n=24, mean age — 10.20, of whom 12 were girls) and healthy age-matched controls (n=22, mean age — 9.63, of whom 10 were girls) using a voxel-based morphometry technique in SPM12 package (Statistical Parametric Mapping) in MATLAB R2019b. To minimize false discoveries, we used a stringent procedure to control the family-wise error rate. RESULTS: We found volumetric brain differences between children with OBPP and healthy controls (all FWE-corrected p CONCLUSION: Integrating our findings with previous work, we speculate that the amygdala–hippocampus–entorhinal cortex complex might play a significant role in motor disorders.
Impact of induced moods, sensation seeking, and emotional contagion on economic decisions under risk
2022 · ARTICLE · en
In addition to probabilities of monetary gains and losses, personality traits, socio-economic factors, and specific contexts such as emotions and framing influence financial risk taking. Here, we investigated the effects of joyful, neutral, and sad mood states on participants’ risk-taking behaviour in a simple task with safe and risky options. We also analysed the effect of framing on risk taking. In different trials, a safe option was framed in terms of either financial gains or losses. Moreover, we investigated the effects of emotional contagion and sensation-seeking personality traits on risk taking in this task. We did not observe a significant effect of induced moods on risk taking. Sad mood resulted in a slight non-significant trend of risk aversion compared to a neutral mood. Our results partially replicate previous findings regarding the presence of the framing effect. As a novel finding, we observed that participants with a low emotional contagion score demonstrated increased risk aversion during a sad mood and a similar trend at the edge of significance was present in high sensation seekers. Overall, our results highlight the importance of taking into account personality traits of experimental participants in financial risk-taking studies.
"Expert persuasion" can decrease Willingness to Pay for sugar-containing food
2022 · ARTICLE · en
Recent studies have revealed types of eating nudges that can steer consumers towards choosing healthier options. However, most of the previously studied interventions target individual decisions and are not directed to changing consumers’ underlying perception of unhealthy food. Here, we investigate how a healthy eating call - first-person narrative by a health expert - affects individuals’ willingness to pay (WTP) for sugar-free and sugar-containing food products. Participants performed two blocks of a bidding task, in which they had to bid on sweets labeled either as “sugar-free” or as “sugar-containing”. In-between the two blocks, half of the participants listened to a narrative by a dietary specialist emphasizing the health risks of sugar consumption, whereas the remaining participants listened to a control narrative irrelevant to food choices. We demonstrate that the health expert’s narrative decreased individuals’ WTP for sugar-containing food, but did not modulate their WTP for sugar-free food. Overall, our findings confirm that consumers may conform to healthy eating calls by rather devaluating unhealthy food products than by increasing the value of healthy ones. This paves the way for an avenue of innovative marketing strategies to support individuals in their food choices.
