Motor imagery (MI) encompasses kinesthetic motor imagery (KMI), internal visual-motor motor imagery (IVMI), and external visual-motor motor imagery (EVMI). This study explored α/β oscillations during MI of left-/right-hand movement from KMI/IVMI/EVMI perspectives in a group of left- (N = 20) and right-handed (N = 20), volunteers selected based on their laterality quotient (RH > 80; LH > -80). We analyzed changes in the power of α/β oscillations from visual- and motor-related clusters of independent components, connectivity (imaginary part of coherence; ICOH) between electroencephalographic activity from selected regions of interest (ROIs), and the correctness of the MI.

We were specifically interested in identifying spatial scaling strategies as well as effects of different scaling directions (up versus down) on participants' performance. To this aim, we asked late blind participants (with visual memory, Experiment 1) and early blind participants (without visual memory, Experiment 2) as well as sighted blindfolded controls to encode a map including a target and to place a response disc at the same spot on an empty, constant-sized referent space.

At the same time, cognitive decline is a well-documented phenomenon accompanying the aging process. Nevertheless, it is acknowledged that aging can also be related to positive processes that allow one to compensate for the decline.

However, research on drawings produced by blind people has mainly been qualitative. The current experimental study was designed to investigate the under-researched issue of the size of drawings created by people with blindness.

Following previous research, we predicted the usage of mental transformation strategies. In all conditions, participants (N = 90, aged 19-28 years) were presented with tactile, colored graphics which allowed to visually and haptically explore spatial information.

This has been confirmed by studies showing the effects of changes in visual stimulation changes on cerebral activity during different tasks, e.g.

While there is an abundance of research showing an association between SCC, well-being, and effective self-regulation, there is little knowledge about how SCC relates to basic cognitive processes such as attention and memory. Drawing on the attentional function theory of cognitive control, we hypothesized that low SCC is associated with greater attentional control during a trait assessment task.

In our study, we wanted to investigate the effect of implicitly learned spatial and temporal sequential predictability on performance in a localization task in a paradigm in which covert selective attention is engaged. We were also interested in the neural mechanism of the facilitating effect of the predictable spatio-temporal context on visual search processes.

Empathy is a phenomenon that brings together both emotions and an understanding of another person. Recent studies have disentangled the mechanisms of empathy into emotional and cognitive aspects. Event-related potential (ERP) studies suggest that emotional empathy is related to the modulation of the amplitude of early ERPs, and cognitive empathy is linked to later ERPs.

At the same time, the study of neurocognitive processes in real-life situations requires good control of all variables relevant to the results. One possible solution that combines the capability of creating realistic experimental scenarios with adequate control of the test environment is virtual reality.

Background: SD in flight is the leading cause of human error-related aircraft accidents in the military, general and commercial aviation, and has been an unsolved problem since the inception of flight. In-flight safety research, visually scanning cockpit instruments, and detecting changes are critical countermeasures against SD.
Recent studies show that during a simple movement imagery task, the power of sensorimotor rhythms differs according to handedness. However, the effects of motor imagery perspectives on these differences have not been investigated yet. Our study aimed to check how handedness impacts the activity of alpha (8-13 Hz) and beta (15-30 Hz) oscillations during creating a kinesthetic (KMI) or visual-motor (VMI) representation of movement.

We hypothesized that paintings evaluated as beautiful compared to nonbeautiful would be associated with different oculomotor behavior in terms of fixation duration, viewing time, and temporal and spatial distribution of attention. To verify these hypotheses, we examined forty participants that looked at and evaluated 140 figurative paintings while their eye movements were recorded.

Neuroimaging evidence suggests that there are two aspects of empathy which are subserved by distinct brain networks. The emotional aspect of empathy is reflected by bottom-up processes and the cognitive aspect of empathy is influenced by top-down processes.

Additionally, we aimed to explore how information about the artist's disability changes the viewer's aesthetic emotions.

The purpose of the present study was to identify the effect of acoustic neurofeedback on brain activity during consecutive stages of mental rotation of 3D objects. Given the fact that the process of mental rotation of objects is associated with desynchronisation of beta rhythm (beta ERD), it was expected that suppression in this band would be greater in the experimental group than in the controls. Thirty-three participants were randomly allocated to two groups performing the classic Shepard-Metzler mental rotation task (1971).

Focal and ambient modes were identified by averaging EFRP waveforms about the beginning of long eye fixations followed by short saccades and short fixations followed by long saccades, respectively. Thirty experts with formal training in visual arts and thirty-two non-experts freely viewed 150 figurative paintings presented for 20 s, each.

Presumably, this happens because temporal distance protects one from encountering the negative emotions produced when facing risk. However, no study has tested whether people that made a choice in the presence of temporal distance would actually change their decision later on (in the absence of temporal distance), towards the safer choice.

The auditory system is not as heavily involved in the pilot's spatial orientation as the visual and vestibular systems; however, it plays a significant role in the cockpit for communication and warning information. The aim of this research was to investigate the combined effect of selective auditory attention and simulator-induced spatial disorientation (SD) cues on pilots' flight performance. We hypothesized that the flight performance in both disoriented and oriented flight profiles would be impaired by selective auditory attention.

Several studies have suggested that positive affect decreases proactive control compared to neutral affect. However, these studies only focused on the valence of affect and often omitted two of its components: arousal and approach motivation.

We compared EEG patterns of professional pianists and non-pianists, who either executed or imagined finger tapping movements of different complexity. Results show that the power in alpha (8-12 Hz) and beta (13-30 Hz) rhythms decreases with the complexity of both performed and imagined movements.
