“…This conclusion is supported by a former study (Carmon et al, 1972) in which Hebrew letters elicited shorter latencies in the right visual field, as did English letters (Moscovitch & Catlin, 1970;Rizzolatti et al, 1971). The results of the present study contradict earlier reports (Harcum, 1966;Harcum & Filion, 1963;Harcum & Finkel, 1963) that 5s who demonstrated right-visual-field superiority in recognizing normally oriented words showed a slight tendency to left-visual-field superiority in recognizing mirror-image words. It might be argued that the visual reaction time differences do not obey the same laws as accuracy of recognition in the two fields.…”

“…In the present study, an attempt was made to clarify whether right visual field superiority, in terms of shorter latencies to verbal material, transcends the directional scanning tendencies associated with the stimuli. The study used an experimental paradigm in which a reversal in directional orientation of the stimuli was found to be associated with a reversal in the direction of visual field recognition superiority, Harcum and Filion (1963), Harcum andFinkel (1963), andHarcum (1966) compared perception of normally oriented English words with that of mirror images of the same words. Their findings show that the mirror images were perceived better in the field opposite to which normally oriented words are more efficiently recognized.…”

Two hypotheses explaining visual hcmifield reaction time (RT) differences were examined. The RTs to normally oriented and to mirror-image English words were compared in the right and left fields in order to decide whether cerebral dominance or scanning tendencies account for field superiority. Both types of words yielded faster verbal and manual RTs in the right visual field. This finding, as well as a supplementary finding, of more accurate recognition for mirrorimage words in the right visual field, supports the cerebral dominance hypothesis.

“…If the reader knows that there will be a bilateral presentation of words, he/she will habitually go to the beginning of the line in the LVF, hence maximizing recognition of these words (Harcum & Filion, 1963;Heron, 1957). A reading habits explanation might suggest that for English we learn to scan from left to right.…”

This study investigated the role of cerebral dominance, functional localization, and attentional bias on the recognition of neutral and emotionally charged words presented unilaterally and bilaterally by a tachistoscope to the left and right visual fields of 42 left and 42 right handers. The major findings were: (1) Over-all, right handers perceived more words than left handers; (2) Although more neutral words were perceived, there were no interactive effects for type of word; (3) Unilateral presentation: LVF = RVF for left and right handers; Bilateral presentation: left handers evidenced a left visual-field advantage, right handers evidenced a right visual-field advantage; (4) Directional cuing did not magnify the existing visual field advantage but increased efficiency of recognition for words presented to the correctly cued nondominant visual field and decreased efficiency of recognition for words presented to the incorrectly cued dominant visual field. It was concluded that, although each hemisphere was equally capable of processing single words, cerebral dominance and functional localization interact with attentional bias to produce the observed differential in word recognition of the left and right visual fields.

“…Wird der Einfluß der gewohnten Leserichtung ausgeschaltet, indem hebräische Wörter in vertikaler Anordnung projiziert werden, erweist sich dagegen auch hier die rechte Gesichtsfeldhälfte als überlegen (i). Umkehr der Leserichtung durch Spiegelschrift soll ebenfalls zur Überlegenheit des linken Gesichtsfeldes führen (23). Augenbewegungen sind aber sicher nicht der einzige relevante Faktor (zz)…”

Die funktionelle Asymmetrie der beiden HirnhemisphärenBei der Katze, dem klassischen Versuchstier der Neurophysiologie, ist das Gehirn nicht nur anatomisch, sondern auch in allen seinen Funktionen bilateral symmetrisch angelegt. Gleiche Verhältnisse bestehen bei den anthropoiden Affen. Beim Menschen dagegen sind wichtige psychologische und sinnesphysiologische Leistungen in der einen oder der anderen Hirnhälfte lateralisiert. Die phylogenetische Entwicklung hat also zu einer funktionellen Differenzierung zwischen den früher gleichwertigen Großhirnhemisphären geführt. Soweit heute bekannt, entsprechen dieser Differenzierung nur minimale Unterschiede im anatomischen Bau der beiden Hemisphären (5).Seit mehr als ioo Jahren hatte sich die Forschung fast ausschließlich auf einen, allerdings besonders eindrucksvollen, K.
