Postural adjustments preceding string release in trained archers.

Optimal postural stability is required to perform in archery. Since the dynamic consequences of the string release may disturb postural equilibrium, they should be integrated into an archer motor programme to optimize postural stability. This study aimed to characterize the postural strategy archers use to limit the potentially detrimental impact of the bow release on their postural stability and identify characteristics that may explain a better performance.

Concurrent Implicit Adaptation to Multiple Opposite Perturbations.

Simultaneous adaptation to opposite visuomotor perturbations is known to be difficult. It has been shown to be possible only in situations where the two tasks are associated with different contexts, being either a different colored background, a different area of workspace, or a different follow-through movement. However, many of these elements evoke explicit mechanisms that could contribute to storing separate (modular) memories.

EEG microstate co-specificity in schizophrenia and obsessive-compulsive disorder.

The past 20 years of research on EEG microstates has yielded the hypothesis that the imbalance pattern in the temporal dynamics of microstates C (increased) and D (decreased) is specific to schizophrenia. A similar microstate imbalance has been recently found in obsessive-compulsive disorder (OCD). The aim of the present high-density EEG study was to examine whether this pathological microstate pattern is co-specific to schizophrenia and OCD.

Unequal opportunities from the start: Socioeconomic disparities in classroom participation in preschool.

Why do socioeconomic disparities in achievement emerge so early in life? Previous answers to this question have generally focused on the perceived deficits of parents from disadvantaged backgrounds (e.g., insufficient childrearing knowledge).

Impact of working memory capacity on predominance of parietal over frontal P300 amplitude.

Working memory-related neural activity varies with task load, and these neural variations can be constrained by working memory capacity (WMC). For instance, some studies suggest that parietal and frontal P300 amplitudes, reflecting working memory functioning, vary differentially with task load and WMC. The present study explored whether the predominance of parietal over frontal P300 amplitude is related to WMC, and whether this relationship varies according to task load.

High treatment resistance is associated with lower performance in the Stroop test in patients with obsessive-compulsive disorder.

Around 50% of the patients with obsessive-compulsive disorder (OCD) are resistant to treatment, and patients with OCD show alterations in a broad range of cognitive abilities. The present study investigated the links between treatment-resistance, executive and working memory abilities, and the severity of OCD symptoms among 66 patients with OCD. The patients performed seven tests gauging their executive functions and working memory and filled in questionnaires for OCD severity and insight into their pathology.

Effect of environmental enrichment on relapse rates in patients with severe alcohol use disorder: protocol for a randomised controlled trial.

Introduction: Alcohol use disorder (AUD) ranks among the most prevalent psychiatric disorders worldwide. Despite current treatments, more than half of patients relapse within weeks after treatment. In animal models, exposure to environmental enrichment (EE) has been shown to be a promising approach to reduce relapse.

The respective contribution of cognitive control and working memory to semantic and subjective organization in aging.

Organizing information is beneficial to episodic memory performance. Among several possible organizational strategies, two consist of organizing the information in semantic clusters (semantic organization) or self-organizing the information based on new associations that do not exist in semantic memory (subjective organization). Here, we investigated in a single study how these two organizational behaviors were underlined by different controlled processes and whether these relations were subjected to age-related differences.

Orthorexic eating behaviors are not all pathological: a French validation of the Teruel Orthorexia Scale (TOS).

As no French validated measurement tool distinguishing healthy orthorexia (HeOr) from orthorexia nervosa (OrNe) currently exists, this study aimed at examining psychometric properties of the French version of the Teruel Orthorexia Scale (TOS). A sample of 799 participants (Mean [SD] age: 28.5 [12.

Looking for a word or for its meaning? The impact of induction tasks on adolescents' visual search for verbal material.

An eye-tracking experiment was conducted to examine whether the pre-activation of different word-processing pathways by means of semantic versus perceptual induction tasks could modify the way adults and 11- to 15-year-old adolescents searched for single target words within displays of nine words. The presence within the search displays of words either looking like the target word or semantically related to the target word was manipulated. The quality of participants' lexical representations was evaluated through three word-identification and vocabulary tests.

No mercy for victims: Exploring the link between dark personality traits, aggressive video game behavior, and severe traffic violations.

This study investigates the relationship between dark personality traits, aggressive behavior in violent video games, and severe traffic violations among 200 driving offenders from Tehran, Iran, participating in a rehabilitation program. Participants engaged in a computerized shooting decision task, where their tendency to shoot unarmed targets (innocent victims), compared to armed targets (criminals), was used as an indicator of aggressive behavior toward innocent victims. Additionally, they completed self-report measures of narcissism, Machiavellianism, psychopathy, and sadism to evaluate the impact of Dark Tetrad personality traits on their behavior.

Point-light display: a new tool to improve verb recovery in patients with aphasia? A pilot study.

Some studies have demonstrated that Action Observation (AO) could help patients with aphasia to recover use of verbs. However, the role of kinematics in this effect has remained unknown. The main aim was to assess the effectiveness of a complementary intervention based on the observation of action kinematics in patients with aphasia.

Video games and board games: Effects of playing practice on cognition.

The worldwide popularity of playing practices has led to a growing research interest in games' impact on behavior and cognition. Many studies have already reported the benefits of both video games and board games for cognitive functions. However, these studies have mainly defined the term players according to a minimum play time or in connection to a specific game genre.

Vocabulary and reading comprehension: what are the links in 7- to 10 year-old children?

The aims of the present study are: (1) to examine the contribution that vocabulary makes to reading comprehension in the Simple View of Reading model in French-speaking children aged from 7 to 10 years based on the use of an index of efficiency (i.e., speed-accuracy index); and (2) to investigate the extent to which the contribution of vocabulary to reading comprehension might change according to children's school grade level.

Relative contributions of postural balance mechanisms reveal studying the CoP displacement alone may be incomplete for analysis of challenging standing postures.

Background: The mechanical consequences of the motor actions used to maintain upright standing balance can be discriminated in two mechanisms: i) moving the center of pressure (CoP) within the base of support (M1); and ii) modifying the whole-body angular momentum (M2). Since the contribution of M2 to the whole-body CoM acceleration increases with postural constraints, a postural analysis focusing only on the CoP trajectory (i.e.

Unperceived motor actions of the balance system interfere with the causal attribution of self-motion.

The instability of human bipedalism demands that the brain accurately senses balancing self-motion and determines whether movements originate from self-generated actions or external disturbances. Here, we challenge the longstanding notion that this process relies on a single representation of the body and world to accurately perceive postural orientation and organize motor responses to control balance self-motion. Instead, we find that the conscious sense of balance can be distorted by the corrective control of upright standing.

[Aging, memory performance and metacognitive beliefs: a narrative review].

Aging is characterized by an increase in older adults’ negative beliefs about their memory. These negative metamemory beliefs are thought to decrease their motivation to engage in memory tasks and to implement effective memory strategies leading to decreased memory performance. Memory assessment conditions tend to accentuate this phenomenon by increasing the salience of negative metamemory beliefs, resulting in an artificial reduction in memory performance (i.

Attentional Refreshing in the Absence of Long-Term Memory Content: Role of Short-Term and Long-Term Consolidation.

Contradictory results in the literature suggest that attentional refreshing can seemingly not operate efficiently in the absence of semantic representations, while at the same time it does not rely directly on retrieval from semantic memory. The objective of the present study was a better understanding of the bidirectional links between working memory (WM) and long-term memory (LTM), by assessing on the one hand the role of WM mechanisms in long-term recall and on the other hand how their functioning is modulated by the prior LTM content. Through two experiments, we investigated a new hypothesis: attentional refreshing requires stable WM representations independently of the presence or the absence of associated LTM traces.

Emotional face recognition when a colored mask is worn: a cross-sectional study.

Studies of the impact of face masks on emotional facial expression recognition are sparse in children. Moreover, to our knowledge no study has so far considered mask color (in adults and in children), even though this esthetic property is thought to have an impact on information processing. In order to explore these issues, the present study looked at whether first- and fifth-graders and young adults were influenced by the absence or presence (and color: pink, green, red, black, or white) of a face mask when asked to judge emotional facial expressions of fear, anger, sadness, or neutrality.

The protective effect of educational level varies as a function of the difficulty of the memory task in ageing.

Unlabelled: This study aimed to explore the effects of age and educational level on recall performance and organisational strategies used during recall as a function of the level of memory task difficulty. Younger ( = 55, age range = 20-39 years) and older ( = 45, age range = 65-75 years) adults learned a word list where the words were either already semantically grouped (easier) or presented in pseudo-random order (harder), and then recalled the words. The number of words recalled was calculated, and an index of clustering was computed to assess organisational strategies.

A plausible link between the time-on-task effect and the sequential task effect.

Mental fatigue can be studied by using either the time-on-task protocol or the sequential task protocol. In the time-on-task protocol, participants perform a long and effortful task and a decrease in performance in this task is generally observed over time. In the sequential task protocol, a first effortful or control task is followed by a second effortful task.

Load-Dependent Prefrontal Cortex Activation Assessed by Continuous-Wave Near-Infrared Spectroscopy during Two Executive Tasks with Three Cognitive Loads in Young Adults.

The present study examined the evolution of the behavioral performance, subjectively perceived difficulty, and hemodynamic activity of the prefrontal cortex as a function of cognitive load during two different cognitive tasks tapping executive functions. Additionally, it investigated the relationships between these behavioral, subjective, and neuroimaging data. Nineteen right-handed young adults (18-22 years) were scanned using continuous-wave functional near-infrared spectroscopy during the performance of n-back and random number generation tasks in three cognitive load conditions.

Childbirth as an anticipated trauma during pregnancy: pretraumatic stress symptoms in primiparous women.

Introduction: Women can develop anticipated traumatic reactions related to the forthcoming delivery through "pretraumatic stress" symptoms. The present study aims at: a) exploring the frequency of probable pretraumatic stress disorder in primiparous pregnant women, b) evidencing associated features of pretraumatic stress symptoms and c) exploring which specific components of antenatal anxiety are associated with pretraumatic stress symptoms.

Methods: A sample of 100 primiparous pregnant women completed an online questionnaire assessing pretraumatic stress, fear of childbirth, depressive and anxiety symptoms.
