“…ERP studies also have shown that words elicit a larger N170 in the LH, as compared with strings of symbols (e.g., Maurer, Brandeis, & McCandliss, 2005). Consistent with these findings, a classical right-visual-field (RVF)/LH advantage in reading English words has been consistently reported, demonstrated first in tachistoscopic recognition (e.g., Bryden & Rainey, 1963) and subsequently in other word recognition tasks, including lexical decision (Faust, Babkoff, & Kravetz, 1995) and word-naming (Brysbaert & d'Ydewalle, 1990) tasks. This RVF/LH advantage has been argued to be linked to the LH superiority in language processing-in particular, phonological processing-and has been shown to interact with sex and handedness (e.g., Voyer, 1996).…”

Previous studies have shown a right-visual-field (RVF)/left-hemisphere (LH) advantage in Chinese phonetic compound pronunciation. Here, we contrast the processing of two phonetic compound types: a dominant structure in which a semantic component appears on the left and a phonetic component on the right (SP characters), and a minority structure with the opposite arrangement (PS characters). We show that this RVF/LH advantage was observed only in SP character pronunciation, but not in PS character pronunciation. This result suggests that SP character processing is more LH lateralized than is PS character processing and is consistent with corresponding ERP N170 data. This effect may be due to the dominance of SP characters in the lexicon, which makes readers opt to obtain phonological information from the right of the characters. This study thus shows that the overall information distribution of word components in the lexicon may influence how written words are processed in the brain.

“…There too, it has been shown that the RVF superiority for words increases with increasing word length. This is true for accuracy [9,59] and for latency [16,18,25]. Ellis et al [25] suggested that the increase in VHF asymmetry for longer words is due to the fact that abstract letter identities are transmitted over the corpus callosum.…”

“…In the word naming test, subjects had to recognize eight series of 200 five-letter words, randomly presented in LVF and RVF. This task usually provides a clear RVF advantage in righthanded subjects [16]. The object naming test also measured processes of the dominant hemisphere (i.e.…”

“…Lambda indices were not calculated for the object naming test and the clockface reading test, because they are assumed not to reveal valuable information in the latter case [4,39], and error rate was less than 2% in the former case. The point-biserial correlation index and the lambda index of laterality were preferred to other indices, because they allow detailed analysis of individual data [16,17]. Per subject 1,600 observations were made on the a combination of three factors.…”

Two arguments are commonly given in favor of a nasotemporal overlap along the vertical meridian of the visual field: anatomical findings and the existence of macular sparing in hemianopia. A review of the literature, however, points to the weakness of the evidence. The anatomical indications are exclusively based on horseradish peroxidase studies, which can not give an unequivocal answer to the amount of overlap in central vision, and which were not supported by a recent study that made use of the more direct ["C]2deoxy-D-glucose technique. The argument of macular sparing in hemianopia appears to be derived evidence that depends on the validity of the anatomical findings. In addition, behavioral studies consistently failed to find functional confirmation of the overlap. To further test the possibility of bilateral representation in central vision, a new paradigm is proposed. It is argued that if interhemispheric transfer is needed for the processing of foveally presented stimuli, the word-beginning superiority effect should be larger for subjects with left hemisphere dominance than for subjects with right hemisphere dominance. Results are in line with the hypothesis and point to the fact that interhemispheric transfer of visual information may be involved in more processing than usually accepted. It is also noted that transfer time seems to depend on the amount of information that must be transferred, and is significantly shorter than the estimates obtained in visual half field studies.Key words: Corpus callosum; Interhemispheric transfer; Macular sparing; Foveal vision; Optimal viewing position; Visual half field studies vision in the foveal region, a phenomenon called macular or foveal sparing. I will discuss the two arguments successively. Anatomical evidence of a hemiretinal overlapThe anatomical evidence for an overlap between the nasal and the temporal hemiretina comes from studies of unilateral sectioning of the optic tract or unilateral electrophoretic injection of horseradish peroxidase (HRP) into the dorsal lateral geniculate nucleus (dLGN) [ 19,20,35,36,52,53,55]. This technique allows tracing the ganglion cells of the retina which project to the dLGN and from there to the visual cortex. The general finding is that in a strip of about 0.2 mm along the vertical midline, ipsilaterally and contralaterally projecting ganglion cells intermingle. This is true both for cats and monkeys. According to Leventhal et al. [35,36] the overlap is primarily due to the presence of ipsilaterally projecting cells in the nasal hemiretina, rather than to contralaterally projecting cells in the temporal hemiretina. Interhemispheric transfer and the processing of foveally presented stimuliDue to the partial decussation of the optic nerves at the optic chiasm, the human visual field is split in two halves: the left and the right visual field (LVF and RVF). Both hemifields project to the contralateral cerebral hemisphere. That is, stimuli presented in the LVF are transmitted to the right cerebral hemisphere, and stimu...

“…Of course the size of stability depends on typical characteristics of the measuring instrument. However, there are only few studies which have analyzed the test-retest reliabilities in visual half field research (for example, Brysbaert & D'Ydewalle, 1990;Chiarello, Dronkers, & Hardyke, 1984;Fennell, Bowers, & Satz, 1977;Hines, Fennell, Bowers, & Satz, 1980). In a critical review Voyer (1998) concludes that the reliability of laterality effects is small but satisfactory and that it varies with modality, type of task, and specific task used.…”

The aim of the present study was to analyze whether task repetitions which are an inevitable part of repeated measures designs might induce performance alterations specific for gender and hemisphere. Male and female subjects conducted twice a lexical decision, a polygon recognition, and a face discrimination task as a visual half field paradigm with the two experimental sessions repeated by 2 weeks. The results show that only in female subjects can a session effect for the lexical decision and the polygon recognition task be demonstrated which is hemisphere specific. Thus, repeated measures designs seem to have a gender-and hemisphere-specific effects of their own which could confound with other variables under study.
