Immediate Effect of Self-Modelling with Internal Versus External Focus of Attention on Teaching/Learning Gymnastics Motor-Skills.

The aim of this study was to identify the immediate effect of self-modelling with different focus of attention strategies (i.e., internal vs.

Movie editing influences spectators' time perception.

Filmmakers use different techniques (e.g., camera movements, editing) to shape viewers' experience.

Transcriptomic Studies of Antidepressant Action in Rodent Models of Depression: A First Meta-Analysis.

Antidepressants (ADs) are, for now, the best everyday treatment we have for moderate to severe major depressive episodes (MDEs). ADs are among the most prescribed drugs in the Western Hemisphere; however, the trial-and-error prescription strategy and side-effects leave a lot to be desired. More than 60% of patients suffering from major depression fail to respond to the first AD they are prescribed.

Electrophysiological Evidence for A Number-Action Mapping in Infancy.

In the last decades, a growing body of literature has focused on the link between number and action. Many studies conducted on adult participants have provided evidence for a bidirectional influence between numerosity processing and grasping or reaching actions. However, it is not yet clear whether this link is functional in early infancy.

Severe Developmental Dyscalculia Is Characterized by Core Deficits in Both Symbolic and Nonsymbolic Number Sense.

A long-standing debate concerns whether developmental dyscalculia is characterized by core deficits in processing nonsymbolic or symbolic numerical information as well as the role of domain-general difficulties. Heterogeneity in recruitment and diagnostic criteria make it difficult to disentangle this issue. Here, we selected children ( = 58) with severely compromised mathematical skills (2 below average) but average domain-general skills from a large sample referred for clinical assessment of learning disabilities.

Emotional expression visual mismatch negativity in children.

Detection of changes in facial emotions is crucial to communicate and to rapidly process threats in the environment. This function develops throughout childhood via modulations of the earliest brain responses, such as the P100 and the N170 recorded using electroencephalography. Automatic brain signatures can be measured through expression-related visual mismatch negativity (vMMN), which reflects the processing of unattended changes.

Infants' representation of asymmetric social influence.

In social groups, some individuals have more influence than others, for example, because they are learned from or because they coordinate collective actions. Identifying these influential individuals is crucial to learn about one's social environment. Here, we tested whether infants represent asymmetric social influence among individuals from observing the imitation of movements in the absence of any observable coercion or order.

Motor inhibition and its contribution to recovery of dexterous hand use after stroke.

Recovery of dexterous hand use is critical for functional outcome after stroke. Grip force recordings can inform on maximal motor output and modulatory and inhibitory cerebral functions, but how these actually contribute to recovery of dexterous hand use is unclear. This cohort study used serially assessed measures of hand kinetics to test the hypothesis that behavioural measures of motor modulation and inhibition explain dexterity recovery beyond that explained by measures of motor output alone.

Infants expect agents to minimize the collective cost of collaborative actions.

This paper argues that human infants address the challenges of optimizing, recognizing, and interpreting collaborative behaviors by assessing their collective efficiency. This hypothesis was tested by using a looking-time study. Fourteen-month-olds (N = 32) were familiarized with agents performing a collaborative action in computer animations.

Early recognition of familiar word-forms as a function of production skills.

Growing evidence shows that early speech processing relies on information extracted from speech production. In particular, production skills are linked to word-form processing, as more advanced producers prefer listening to pseudowords containing consonants they do not yet produce. However, it is unclear whether production affects word-form encoding (the translation of perceived phonological information into a memory trace) and/or recognition (the automatic retrieval of a stored item).

Flexing the principal gradient of the cerebral cortex to suit changing semantic task demands.

Understanding how thought emerges from the topographical structure of the cerebral cortex is a primary goal of cognitive neuroscience. Recent work has revealed a principal gradient of intrinsic connectivity capturing the separation of sensory-motor cortex from transmodal regions of the default mode network (DMN); this is thought to facilitate memory-guided cognition. However, studies have not explored how this dimension of connectivity changes when conceptual retrieval is controlled to suit the context.

Are infants' preferences in the number change detection paradigm driven by sequence patterns?

Inter-individual differences in infants' numerosity processing have been assessed using a change detection paradigm, where participants were presented with two concurrent streams of images, one alternating between two numerosities and the other showing one constant numerosity. While most infants look longer at the changing stream in this paradigm, the reasons underlying these preferences have remained unclear. We suggest that, besides being attracted by numerosity changes, infants perhaps also respond to the alternating pattern of the changing stream.

[Multiphasic time: Representations, modelisation and dynamics: Putting time back in motion after traumatic violence].

A multiphasic time model, integrating the past, present and future in close interrelations, is first presented and offers a contextual approach to the perceptions and responses of an individual according to his/her personal history and environment. The present and future prospects are in continuity with the past and its consequences and effects. The past, even when it is not or no longer expressed, influences the present and the future, and this over several generations.

Aggressive behavior: A language to be understood.

Aggressive behaviors could be considered as a dynamic of communication, in which aggression is a language to be understood, to be deciphered by two protagonists : the aggressor coping with a stressful and threatening situation and the aggressed individual coping with an aggressive acting out. The following questions are addressed: (a) What does aggression mean to the aggressor, what does it mean to the aggressed individual? (b) What does the aggressor want or try to express, and why does he or she use this mode of expression and action over another? (c) How does the aggressed individual react, and what is the impact of his or her response on the aggressor? This article reviews studies on the definition of aggression, its measurement, its developmental role and its associated risk factors in children and adolescents. First, aggression in children and adolescents with typical and atypical development is examined based on a developmental approach, clinical case studies in child and adolescent psychiatry, and an empirical study on aggression in autism.

Physical distance to sensory-motor landmarks predicts language function.

Auditory language comprehension recruits cortical regions that are both close to sensory-motor landmarks (supporting auditory and motor features) and far from these landmarks (supporting word meaning). We investigated whether the responsiveness of these regions in task-based functional MRI is related to individual differences in their physical distance to primary sensorimotor landmarks. Parcels in the auditory network, that were equally responsive across story and math tasks, showed stronger activation in individuals who had less distance between these parcels and transverse temporal sulcus, in line with the predictions of the "tethering hypothesis," which suggests that greater proximity to input regions might increase the fidelity of sensory processing.

[School bullying and group violence: How to occupy a place in the group by exclusion].

The prevalence of school bullying (a deliberate, repeated act of verbal, physical or relational/social aggression occurring in a situation of inequality, including cyberbullying) is high in France (10 %) as well as in other countries like the United States (more than 40 % of school children have experienced harassment at some point in their school cursus). This frequency varies by country, source of observation, school, class, and age of children. Self-questionnaires where children have to self-identify as harassing or being harassed involve a clear bias of underevaluation (even for harassed children who can feel ashamed to report explicitly harassment).

Optical imaging and spectroscopy for the study of the human brain: status report.

This report is the second part of a comprehensive two-part series aimed at reviewing an extensive and diverse toolkit of novel methods to explore brain health and function. While the first report focused on neurophotonic tools mostly applicable to animal studies, here, we highlight optical spectroscopy and imaging methods relevant to noninvasive human brain studies. We outline current state-of-the-art technologies and software advances, explore the most recent impact of these technologies on neuroscience and clinical applications, identify the areas where innovation is needed, and provide an outlook for the future directions.

Age- and task-dependent effects of cerebellar tDCS on manual dexterity and motor learning-A preliminary study.

Objectives: The role of the cerebellum in motor learning of dexterous control and interaction with aging remains incompletely understood. We compared the effect of age and cerebellar transcranial direct current stimulation (CRB-tDCS) on motor learning in two different manual dexterity tasks, visuomotor force control vs. effector selection (independent finger movements).

What over When in causal agency: Causal experience prioritizes outcome prediction over temporal priority.

Prior expectations strongly structure the way we perceive the world and ourselves. For instance, action-outcome prediction can modulate time perception and causal experience. We designed a study that allowed us to investigate whether action-outcome prediction has similar effects on time perception and intentional causality.

Language specificity in cortical tracking of speech rhythm at the mora, syllable, and foot levels.

Recent research shows that adults' neural oscillations track the rhythm of the speech signal. However, the extent to which this tracking is driven by the acoustics of the signal, or by language-specific processing remains unknown. Here adult native listeners of three rhythmically different languages (English, French, Japanese) were compared on their cortical tracking of speech envelopes synthesized in their three native languages, which allowed for coding at each of the three language's dominant rhythmic unit, respectively the foot (2.

Newborns discriminate utterance-level prosodic contours.

Prosody is the fundamental organizing principle of spoken language, carrying lexical, morphosyntactic, and pragmatic information. It, therefore, provides highly relevant input for language development. Are infants sensitive to this important aspect of spoken language early on? In this study, we asked whether infants are able to discriminate well-formed utterance-level prosodic contours from ill-formed, backward prosodic contours at birth.

Are monkeys sensitive to informativeness: An experimental study with baboons (Papio papio).

Informativeness (defined as reduction of uncertainty) is central in human communication. In the present study, we investigate baboons' sensitivity to informativeness by manipulating the informativity of a cue relative to a response display and by allowing participants to anticipate their answers or to wait for a revealed answer (with variable delays). Our hypotheses were that anticipations would increase with informativity, while response times to revealed trials would decrease with informativity.

Action effect predictions in 'what', 'when', and 'whether' intentional actions.

It has been proposed that intentional action can be separated into three major types depending on the nature of the action choice - what (selecting what to do), when (selecting when to act) and whether (to perform the action or not). While many theories on action control assume that intentional action involves the prediction of action effects, there has not been any attempt to compare the three types of intentional actions (what, when, whether) with respect to action-effect prediction. Here, we employ an action-effect prediction paradigm where participants select the action on every trial based on either the what (choosing between alternative actions), when (choosing to respond at different time points) or whether (choosing to perform an action or not) action components, and each action choice is followed by either a predicted (standard) or a mispredicted (deviant) tone.

Visual foundations of Euclidean geometry.

Geometry defines entities that can be physically realized in space, and our knowledge of abstract geometry may therefore stem from our representations of the physical world. Here, we focus on Euclidean geometry, the geometry historically regarded as "natural". We examine whether humans possess representations describing visual forms in the same way as Euclidean geometry - i.

Serial dependence tracks objects and scenes in parallel and independently.

The visual world is made up of objects and scenes. Object perception requires both discriminating an individual object from others and binding together different perceptual samples of that object across time. Such binding manifests by serial dependence, the attraction of the current perception of a visual attribute toward values of that attribute seen in the recent past.
