Past investigations into the connection between space and numbers have revealed its potential vulnerability to external influences such as cultural factors, including language. This study aims to examine whether language moderates the association between space and number in the spatial-numerical association of response codes (SNARC) effect, which is demonstrated in an interaction between number magnitude and response side. The SNARC effect has been observed across various stimuli.

Both components were suggested as underlying neural mechanisms of cognitive dysfunctions in attention-deficit/hyperactivity disorder. Here, we examined differences in processing speed and resting-state-Electroencephalogram neural oscillations and their associations between 6- and 12-year-old children with (n = 33) and without (n = 33) attention-deficit/hyperactivity disorder.

This debate has been fuelled by contradictory and nuanced experimental findings. Notably, the effectiveness of a given treatment is commonly evaluated by comparing the effect of the active treatment versus the placebo on human health and/or behaviour.

Other research has highlighted the benefits of high-frequency transcranial random noise stimulation (tRNS)-an excitatory form of neurostimulation-on learning. We examined the E/I as a potential mechanism and studied whether tRNS effect on learning depends on E/I as measured by the aperiodic exponent as its putative marker.

Here, we examined whether a novel form of stimulation, high-frequency transcranial random noise stimulation (tRNS), applied with cognitive training (CT), may impact symptoms and neural oscillations in children with ADHD. We conducted a randomized, double-blind, sham-controlled trial in 23 unmedicated children with ADHD, who received either tRNS over the right inferior frontal gyrus (rIFG) and left dorsolateral prefrontal cortex (lDLPFC) or sham stimulation for 2 weeks, combined with CT.

As neuroticism is more reactive to negative affects, the current follow-up experiment explores the effect of affective perspective taking (APT) when perspectives are derived from extroversion, which is more reactive to positive affects. Stimuli consisted of neutral, sad, and happy pictures, which were rated from the perspectives of an introvert and an extrovert.

The current follow-up experiments extend that research to explore effects of perspective taking with positive valence pictures. We used stimuli consisting of neutral, happy and sad pictures.

Manipulation of mood is appropriate for investigations of long-term effects while affective priming is limited to short intervals (approximately 300 ms) between a prime and target. However, studying the influence of real-world rapidly changing emotional episodes on perception may fall between the cracks of these methods.

Among deaf signers, the fingers also serve as a tool for communication in sign language. Previous studies in normal hearing (NH) participants showed effects of embodiment (i.

For example, OCD patients were shown to benefit from a computerized training program which aimed to create an association between OCD-related cues and stopping behaviors. In the current study, we aimed to investigate the ability to condition inhibition to specific stimuli and whether such conditioning can be generalized between tasks to last over time.

In the current study, we aimed to investigate the effect of a non-emotional common environmental cue-a traffic light-on a higher cognitive operation-inhibition. In two experiments, we administered a novel version of the stop-signal task, in which the go task was to determine the color of a traffic light.
