“…The asymmetry index (AI) is designed to find the differences between the right and left hemispheric functional networks. The AI of the brain networks was calculated according to Argyropoulos et al [ 49 ] with the following formulation: AI( X ) = 100 × (∣ X (R)∣−∣ X (L)∣)/ N , where X (R) and X (L) represent the degree of centrality absolute value of the right and left hemispheres, respectively. N represents the number of parcels/channels for each hemisphere, 42 for MR-FC and 15 for EEG-FC.…”

The present study explores the correlation between electroencephalographic and neuroimaging asymmetry index from EEG-MRI functional connectome and EEG power analysis in inattention, motion, and mixed profile subgroups of ADHD. Sixty-two subjects from Healthy Brain Network Biobank of the Child Mind Institute dataset were selected basing on the quotient score. From both MRI and EEG asymmetry index, Pearson’s correlation, ANOVA, and partial least square analysis were performed matching left and right brain parcels and channels. The asymmetry index significantly correlated across subjects between fMRI and power-EEG in the inattention group in frontal and temporal areas for theta and alpha bands, an anticorrelation in the same areas for delta band was found. Significant patterns of hemispheric asymmetry index have been reported, involving EEG bands that underlie cognitive impairments in ADHD. Alpha and theta bands were altered in the inattention group of patients, reflecting widespread deficiency of basic attentional processing.

“…Therefore, the follow-up of this study is the use of a handedness assessment tool. For instance, it is expected that the modified version of the Edinburgh Handedness Inventory and the Waterloo Handedness Questionnaire with relevant modifications for individuals with visual impairment and blindness (Argyropoulos et al, 2014) may work well for the needs of the present study.…”

“…Some studies report a left-hand advantage in recognizing objects, while others highlight advantages in using both hands and multiple fingers (Morash, Pensky, Tseng & Miele, 2014). In fact, it has been observed that visual impairment affects not just the choice of hand but also the degree of handedness (Argyropoulos, Sideridis & Papadimitriou, 2014). Finally, many studies of haptic object recognition do not mention or control handedness or permitted bimanual exploration (Craddock & Lawson, 2009;Stone & Gonzalez, 2014).…”

Research is still ongoing with regard to types of exploratory movement by active touch and its key functions in individuals with visual impairment. The aim of the present study was to describe and identify different types of exploratory movement performed by individuals with visual impairment in their exploration of geometric shapes. A total of twelve participants were asked to explore a number of simple and complex geometric shapes. The research design consisted of two research phases. In the first phase, the participants were asked to describe and, if possible, to identify the properties of each shape. In the second phase, the participants were asked to describe their hand movements during active exploration. The findings indicated that the participants utilized different movements to extract the featural and global properties of the shapes. It was also observed that some patterns of exploratory movement were present in all of the participants’ strategies, which indicated issues of laterality. Finally, the research highlighted that by observing patterns of exploratory movement, educators of students with visual impairment can determine which strategies may be worth exploring with a view to their adoption in teaching practices and instruction. Keywords: visual impairment, active touch, geometric shapes, think -aloud protocols, laterality, teaching practices

“…Handedness was defined according to the items of the modified Edinburgh Handedness Inventory (EHI) (Argyropoulos et al 2014). More specifically, this instrument is a modified version of the EHI (Oldfield 1971) and the Waterloo Handedness Questionnaire (Bryden 1977;Bryden and Steenhuis 1991) with relevant modifications for the population of individuals with visual impairments and blindness.…”

Research results with regard to handedness and braille reading performance are contradictory. The present study investigated (a) the effects of handedness on braille reading performance in people with blindness (or severe visual impairment) and (b) the potential effects of vision loss (or type) of blindness on braille reading. Forty-nine (27 males and 22 females) aged 8 to 27 years participated in three braille reading accuracy tasks with a subset of a standardized instrument, which evaluated reading accuracy in Greek language. Handedness was defined through a modified version of the Edinburgh Handedness Inventory. The analysis showed that handedness was not significantly related to any task of braille reading accuracy. Level of vision loss was found to play an important role in reading accuracy, favoring the participants with blindness regardless of hand preference. The results may add to the literature by providing evidence that it is possible for braille-reading students to incorporate both hands in reading, regardless of which hand is dominant.
