This paper presents a case study of a 10-year-old Chinese-English bilingual boy, who has developmental dyslexia and exhibits a discrepancy in reading and writing skills between the two languages. This discrepancy is believed to be influenced by the different orthographic characteristics and cognitive demands of the two languages. The study investigated the reasons behind his literacy skills profile from both orthographic and cognitive perspectives. To achieve this, the researchers assessed the boy’s literacy skills, receptive vocabulary, and cognitive abilities (including phonological skills, naming speed, and visual skills) in both Chinese and English. The preliminary results showed that the bilingual child’s reading skills in English were on par with bilingual children, although lower than English monolingual children. This case study supports the cognitive account theory, suggesting that the different cognitive demands required for literacy skill development can lead to discrepancies in these skills, particularly in terms of accuracy, in bilingual children.

Human communication, known to occur between two individuals using various modalities, has attracted significant interest, particularly in the context of neural dynamics’ studies. Embodied communication, especially in cooperative or competitive scenarios, has been a focal point of these studies. However, the neural activity during this process is not well understood from the viewpoint of motor intention in communication. It is crucial to note that intentional motor switching occurs following motor coordination within a pair. In this study, we conducted a simultaneous recording of EEG, motion, and gaze of two players engaged in our newly devised coordination game involving bodily motions. We observed significant differences in time-frequency power during cooperative and competitive situations in intentional motor switching. This finding suggests that the EEG power differences in local brain regions and in the alpha and high frequency bands are effectively related to the process of intentional motor switching.

Neural Activities in Intentional Motor Switching after Coordinating Bodily Motions in Pairs

The seminal dual coding theory by Paivio (1971) posited that non-verbal and verbal stimuli differ in their representational format, whereby the former activates a dual code while the latter only a single one. These differences in code have implications for tasks such as visual search. The current eye-tracking visual search study aims to re-evaluate this theoretical framework while examining the role played by semantic processing, that has never been looked at before. We followed the original design by Paivio and Begg (1974), with participants searching for a target, cued either as a word or as a picture, in an array of either words or pictures. The target could be either semantically related or unrelated to the other distractors. Corroborating original results, response times for correct trials were faster in pictorial arrays and substantially slower when a cued picture had to be found in a word array. Semantically unrelated targets were looked at faster, for longer, and leading to overall shorter search responses than semantically related targets. Critically, these effects driven by semantic relatedness were amplified when codes had to be converted (e.g., picture-to-word). Our findings refine our understanding of the role semantic processing plays in the representational format of words and pictures and the implications it carries for visual search.

Semantic Processing Modulates the Attentional Accessibility of Verbal and Nonverbal Search Targets

Studies examining the impact of Focussed attention meditation on mismatch negativity (MMN) have yielded inconsistent and conflicting results, emphasizing the necessity for well-powered studies examining different meditation styles to comprehend MMN modulation. Addressing methodological issues from previous research, the present study focuses on expertise in mantra meditation, akin to focused attention meditation, employing a sufficiently powered investigation with a novel intensity MMN paradigm. This paradigm introduces both louder and quieter deviants to discern whether Meditation-induced MMN effects signify higher-order cognitive processes or result from sensory adaptation. While the findings indicate a tendency of higher MMN in novices compared to experts, statistical significance was not achieved. The modest effect is attributed to enhanced attention skills in novices through consistent practice. The consistent unidirectional polarity shift in event-related potential (ERP) to both deviant stimuli types suggests that intensity-related MMN effects may not solely rely on loudness-dependent modulation of sensory components but could signify higher-order deviance detection. Results from eLORETA source localization are consistent with bilateral temporal and frontal cortex activity, which had lower amplitudes for the expert mantra meditator group compared with novices.

Influence of mantra meditation on intensity mismatch negativity

Our senses receive a continuous stream of complex information. According to Event Segmentation Theory (EST), we parse this information into meaningful events, allowing us to extract relevant information, remember it, and act upon it. Previous research has related these events to so-called ‘neural states’: temporally and regionally specific stable patterns of brain activity, which tend to coincide with events in the stimulus. Here we show that these neural states additionally align with stable features in a movie stimulus that are relevant to a specific brain region. This supports the idea that many brain areas across the cortex apply event segmentation in a hierarchical manner. Using intracranial measurements, we further investigate whether neural states are present at a much smaller timescale and how their characteristics correspond to EST. Our initial findings provide support for the idea that neural states could underlie the cognitive skill of event segmentation.

The neural basis of Event Segmentation Theory during naturalistic perception: stable neural activity patterns throughout the cortex

Speech production in aphasia is often described as “effortful”, though the consequences of consistent, high degrees of cognitive effort have not been explored. Using recent work on mental effort as a theoretical framework, the present study examined how effort-related fatigue produces decrements in performance in picture naming among participants with post-stroke aphasia. We analyzed three data sets from prior studies where participants completed a large picture naming test. Decreasing naming accuracy across trials was statistically significant in two of the three samples. There were also significant effects of practice (better performance on a second test administration), word frequency (better performance for more frequent words), and word length (better performance for shorter words). These results are the first concrete demonstration of fatigue affecting performance on a language task in post-stroke aphasia. They open a new avenue for research on mental effort/fatigue with potential implications for aphasia assessment, treatment, and management.

Effect of Fatigue on Word Production in Aphasia

According to Bayesian accounts, perception is the consequence of integrating sensory input with prior expectations, resulting in biased percepts attracted towards our expectations. Contrary to this logic, Phan et al. show that downward motion is perceived as less accelerating than upward motion: a repulsion from the expectation that downward-moving objects should accelerate. This is one of a small number of reported effects where perception is repulsed from expectation. The question then arises, under what conditions do repulsion effects emerge, and why? Here we manipulated the expected acceleration profiles for context and object identity along the horizontal axis, asking whether we see repulsion effects similar to those observed by Phan et al. We find repulsion when expectations are related to the context in which a ball moves, but attraction when an association is made between the ball’s colour and the acceleration profile. We discuss possible reasons and implications for the contradictory results.

Attraction and repulsion effects of expectation on the perception of acceleration.

The neurocognitive processes involved in understanding objects and scenes remains debated, such as the separability of electrophysiological responses thought to index object identification (N300) and semantic access (N400). Yet, studies typically introduce incongruities which evoke N300/N400 patterns, not different deflections. We measured EEG to naturalistic comic strips with panels that “zoomed-in” on scene content. In Experiment 1, zoom and full-scene panels were compared within sequences that were in/congruous to the sequence. Incongruities evoked larger negativities for both the N300 and N400, while zoom panels elicited attenuated N300s yet enhanced N400s. In Experiment 2, zoom and full-scene panels appeared in succession. Both types evoked attenuated N400s when appearing second, benefiting from the repetition effect, but N300s were less negative for zooms than full panels. Across both experiments, these opposite patterns of deflections across components suggest differential processes of object identification (N300) and semantic access (N400) in the processing of visual information.

Dissociable neurocognitive signatures in scene perception

Transauricular vagus nerve stimulation (taVNS) is increasingly spreading both in research and clinical practice; however, literature often presents non-uniform results in various cognitive domains. We propose a procedure based on the use of taVNS to investigate its effect on executive functions, also considering the modulation of the homeostatic balance between the sympathetic and parasympathetic systems. 40 (22F) volunteers participated in two separate sessions (stimulation/sham). After baseline measurements (heart rate variability) and a preliminary stimulation phase, they performed Stroop and go/no go tasks. Throughout the procedure, cardiac activity was recorded to obtain HRV parameters in different experimental conditions. Although performance differences were not identified in the tasks, the modulation of HRV parameters during the tasks indicates how taVNS can influence the balance between the sympathetic and parasympathetic systems during the execution of cognitive tasks. This effect is likely attributed to the taVNS acting on vagal tone, supporting the parasympathetic component.

The role of transauricular vagus nerve stimulation in balancing autonomic systems during cognitive tasks

Distinguishing relevant features from noise is a central challenge for efficient behaviour. We asked whether humans address this challenge by leveraging the insight that behaviourally relevant processes change on a slower timescale than noise. To test this idea, participants were asked to learn the rewards of two-dimensional bandits when either a slowly or quickly changing feature of the bandit predicted reward. Participants accrued more reward and achieved better generalisation to unseen bandits when the reward-predictive feature changed slowly, rather than quickly. Participants were also more likely to incorrectly base their choices on the reward-irrelevant feature when it changed slowly. Computational modelling showed that participants adjusted their learning rates based on feature speed. Those who learned better from slow features also had higher learning rates for it from the onset. These results provide evidence that human reinforcement learning favours slower features, suggesting a bias in how humans approach reward learning.

An inductive bias for slowly changing features in human reinforcement learning

Extensive research from both sensorimotor and perceptual domains has shown that people make decisions by combining prior and current information according to their relative uncertainties, following Bayesian statistics predictions. However, less is known about visual search, a task that requires people to determine the presence/absence of a search target (T) amongst distractors (Ls). Here, we examined decision-making behavior in a visual search task which manipulated the target prevalence rate (prior: 25% or 50%) and the portion of the display that was visible (sensory information: 0%, 30%, or 60%). Participants’ (N=57) decision-making behavior qualitatively reflected Bayesian predictions, relying more on the information that was less uncertain. When no items were visible, participants were highly accurate in making present/absent decisions based on the prevalence rate learned through feedback. However, when provided sensory information, participants’ decision-making was more strongly influenced by visibility. Thus, reliance on sensory information may dominate priors in visual search.
