Mental imagery is a complex cognitive process that resembles the experience of perceiving an object when this object is not physically present to the senses. It has been shown that, depending on the sensory nature of the object, mental imagery also involves correspondent sensory neural mechanisms. However, it remains unclear which areas of the brain subserve supramodal imagery processes that ar...

Based on our research and experiences in fluid engineering (hydraulics, pneumatics), we have realized tools for drawing, simulating, and structure visualization of electrofluidic circuits. These tools can provide a new quality when analysing or synthesizing fluidic systems since they enable a user to quickly evaluate and modify solutions for hydraulic and pneumatic manipulation problems. This o...

Sensorimotor processing specifically impacts mental body representations. In particular, deteriorated somatosensory input (as after complete spinal cord injury) increases the relative weight of visual aspects of body parts' representations, leading to aberrancies in how images of body parts are mentally manipulated (e.g. mental rotation). This suggests that a sensorimotor or visual reference fr...

Background & Aims:The aim of the present study was to use a psychological model to explain the effect of trait anxiety and induced anxiety on individual’s performance in updating function of working memory. This study was also designed to test attentional control theory of Eysenck et al. Methods: Throngh Multistage Cluster sampling method, 330 freshman un...

The paper presents the experimental plan, methodology and results of research of efficiency and dynamics of complex mental processing in 15 divers (diver demolition specialists) in simulated conditions of diving at the depth not exceeding 30 meters in hyperbaric chamber. Changes in efficiency (total time) and dynamics (speed, stability and accuracy) of mental processing were determined through ...

What is rotated in mental rotation? The implicitly or explicitly most widely accepted assumption is that the rotated representation is a visual mental image. We here provide converging evidence that instead mental rotation is a process specialized on a certain type of spatial information. As a basis, we here develop a general theory on how to manipulate and empirically examine representational ...

As research in speech processing has matured, attention has gradually shifted from linguistic-related applications such as speech recognition towards paralinguistic speech processing problems, in particular the recognition of speaker identity, language, emotion, gender, and age. Determination of a speaker’s emotion or mental state is a particularly challenging problem, in view of the significan...

Representations support learning and instruction in many ways. Two key aspects of representations are discussed in this paper. First we briefly review the research literature about cognition and processing internal mental models. The emphasis is on the role that mental models play in critical reasoning and problem solving. We then present a theoretically-grounded rationale for taking internal m...

Cognitive aging has positive and negative effects on mental abilities. With time and experience, we gain new knowledge and skills. We become wiser. However, for most adults cognitive aging also brings slower mental processing, reduced mental flexibility, increased susceptibility to distraction, and more difficulty learning new things. As an example, the amount of detail recalled from a short st...
