“…Adolphs, Jansari, & Tranel, 2001;Ahern & Schwartz, 1985;Jansari, Rodway, & Goncalves, 2011). The leftward ECFT biases were not significantly affected by a left visual field bias in visuospatial attention, as measured by the Greyscales task (Mattingley et al, 1994;Nicholls, et al, 1999;Nicholls & Roberts, 2002). In addition, the large independent effect observed for the ECFT, and lack of significant correlation between the ECFT and Greyscales task, is inconsistent with the hypothesis that a general attentional asymmetry accounts for left hemiface biases.…”

“…Consistent with the idea of the left of faces and the left of stimuli bias having a common origin, patients with attentional deficits in the left visual field demonstrated right biases in the ECFT and in various pseudoneglect tasks (Mattingley et al, 1994). However, Mattingley et al found no evidence of correlation between ECFT biases and scores on their measure of pseudoneglect (the Greyscales task; Mattingley et al, 1994;Nicholls, Bradshaw, & Mattingley, 1999;Nicholls & Roberts, 2002) within controls or patients. Given the lack of firm evidence regarding the influence of Method Participants 59 participants (27 male, 32 female) from Durham University initially took part in the present experiment.…”

“…Sackheim & Gur, 1978), as 4 well as Levy, Heller, Banich and Burton (1983), who examined asymmetries in emotional facial expression by vertically dividing images of faces and creating mirrored composites from each half of the face, as a task to evaluate hemispheric asymmetries in emotional perception. The task has been used extensively in the years since (Bourne, 2008;2010, 2011Chiang, Ballantyne, & Trauner, 2000;Christman & Hackworth, 1993;Coolican, Eskes, McMullen, & Lecky, 2008;Coronel & Federmeier, 2014;Luh, 1998;Luh, Rueckert, & Levy, 1991;Mattingley, Bradshaw, Nettleton, & Bradshaw, 1994;Rahman & Anchassi, 2012;Rueckert, 2005;Workman, Peters, & Taylor, 2000). In a typical version of the task, neurologically healthy participants are presented with two faces, one placed above the other.…”

AbstractLeft hemiface biases observed within the Emotional Chimeric Face Task (ECFT) support emotional face perception models whereby all expressions are preferentially processed by the right hemisphere. However, previous research using this task has not considered that the visible midline between hemifaces might engage atypical facial emotion processing strategies in upright or inverted conditions, nor controlled for left visual field (thus right hemispheric)visuospatial attention biases. This study used novel emotional chimeric faces (blended at the midline) to examine laterality biases for all basic emotions. Left hemiface biases were demonstrated across all emotional expressions and were reduced, but not reversed, for inverted faces. The ECFT bias in upright faces was significantly increased in participants with a large attention bias. These results support the theory that left hemiface biases reflect a genuine bias in emotional face processing, and this bias can interact with attention processes similarly localized in the right hemisphere.3

“…In line bisection, for example, people typically err by locating the midpoint about 2% to the left of true centre (Brodie & Pettigrew, 1996;Hausmann, Ergun, Yazgan, & Güntürkün, 2002), consistent with dominance of the right hemisphere for visuospatial attention (Fink et al, 2000;Heilman, Jeong, & Finney, 2004;Mattingley, Bradshaw, Nettleton, & Bradshaw, 1994). In contrast, our earlier research showed that musicians bisected lines to the right of centre, and were also more accurate overall than non-musicians (Patston, Corballis, Hogg, & Tippett, 2006).…”

“…The latency of the N1 component has been suggested to reflect visual processing for attended stimuli (Luck, 1995), and previous research has shown the N1 latency to lengthen when attentional demands are increased (Callaway & Halliday, 1982;Schwent et al, 1976). The longer latency in the right hemisphere of non-musicians may thus be explained by the right hemisphere's dominant role in visuospatial attention (Fink et al, 2000;Heilman et al, 2004;Mattingley et al, 1994). In other words, a longer N1 latency in the right hemisphere of non-musicians may reflect an increased attentional capacity for LVF stimuli.…”

Previous behavioural research has shown that spatial attention is bilaterally represented in musicians, possibly reflecting more equal neural development between the hemispheres. We investigated this theory electrophysiologically with another measure that has shown asymmetry, interhemispheric transfer time (IHTT). Sixteen right-handed musicians and 16 matched non-musicians responded to stimuli presented to the left and right visual fields while 128-channel EEG was recorded. IHTT was calculated by comparing the latencies of occipital N1 components between hemispheres. Non-musicians showed significantly faster IHTT in the right-to-left direction than in the left-to-right direction and a shorter N1 latency in the left than in the right hemisphere. In contrast, the musician group showed no directional difference between hemispheres in IHTT, and no hemispheric difference in latency. These results indicate that musicians have more bilateral neural connectivity than non-musicians, reflected in an unusual lack of asymmetry. It is suggested that plastic developmental changes caused by extended musical training in childhood result in equally efficient connections to both hemispheres.
