“…These results indicate that the FR and FL attention conditions may not be identical, and that level of cognitive functioning is more important for effective performance in the FL than in the FR attention condition of DL. This has also been shown in other populations (Beaton, Hugdahl & Ray, 2000; Hugdahl, Bodner, Weiss & Benke, 2003; Hugdahl, Rund, Lund et al , 2003). The task of overriding an existing perceptual asymmetry may require larger cognitive resources than simply increasing an existing asymmetry.…”

Fifty right-handed patients with focal temporal lobe epilepsy were administered a dichotic listening test with consonant-vowel syllables under non-forced, forced right and forced left attention conditions, and a neuropsychological test battery. Dichotic listening performance was compared in subgroups with and without left hemisphere cognitive dysfunction, measured by the test battery, and in subgroups with left and right temporal epileptic focus. Left hemisphere cognitive dysfunction led to more correct responses to left ear stimuli in all three attention conditions, and fewer correct responses to right ear stimuli in the non-forced attention condition. This was probably caused by basic left hemisphere perceptual dysfunction. Dichotic listening was less affected by a left-sided epileptic focus than by left hemisphere cognitive dysfunction. General cognitive functioning influenced dichotic listening performance stronger in forced than in non-forced attention conditions. Larger cerebral networks were probably involved in the forced attention conditions due to the emphasis on conscious effort.

“…CASTRONOVO AND CROLLEN dominant right ear (U-T presentation) compared to when the units were emitted in the dominant right ear (T-U presentation), as expected according to the right-ear-advantage auditory effect in dichotic listening for verbal material (Bryden, 1988;Hugdahl et al, 2003;Kimura, 1967). A significant tens effect was found, F(1, 23) 038.24, p B.001, as response times were 39 ms faster for the tens 30Á70 than for the tens 40Á60.…”

“…Moreover, in our study, the type of ear-side presentation should also have an impact on the attentional weight attributed to the different numerals' components, thanks to the classic auditory phenomenon of Right-Ear Advantage (Bryden, 1988;Hugdahl, Bodner, Weiss, & Benke, 2003;Kimura, 1967) (see for an illustration, Figure 4 in Castronovo & Seron, 2007). In the T-U presentation, the units were emitted in the 10 CASTRONOVO AND CROLLEN dominant right-ear, whereas in the U-T presentation the decades were emitted in the dominant right-ear.…”

The study of two-digit numbers processing has recently gathered a growing interest. Here, we examine whether differences at encoding of two-digit oral verbal numerals induce differences in the type of processing involved. Twentyfour participants were submitted to a comparison task to 55. Differences at encoding were introduced by the use of dichotic listening and synchronous (synchronous condition) or asynchronous presentation (tens-first and units-first conditions) of the two-digit numerals' components. Our results showed that differences at the encoding stage of two-digit numerals involve: (1) different comparison processes (tens-first and units-first conditions: parallel comparison; synchronous condition: parallel and holistic comparison); and (2) differences in the weight of the tens-and units-effects. Therefore, attentional mechanisms determining at the encoding stage how much attention is paid to the two-digit numerals' components might account for the different types of proc...

“…In fact, it has been observed that left frontal lobe lesions diminish the advantage of the right ear (Hugdahl et al, 2003), indicating a functional preference for auditory information processing in the left frontal lobe. Congenitally blind individuals have shown a less pronounced right ear advantage, thus outperforming sighted individuals in, for example, dichotic listening tasks (Hugdahl et al, 2004; Castronovo and Seron, 2007).…”

The causes of schizophrenia are still unknown. For the last 100 years, though, both “absent” and “perfect” vision have been associated with a lower risk for schizophrenia. Hence, vision itself and aberrations in visual functioning may be fundamental to the development and etiological explanations of the disorder. In this paper, we present the “Protection-Against-Schizophrenia” (PaSZ) model, which grades the risk for developing schizophrenia as a function of an individual's visual capacity. We review two vision perspectives: (1) “Absent” vision or how congenital blindness contributes to PaSZ and (2) “perfect” vision or how aberrations in visual functioning are associated with psychosis. First, we illustrate that, although congenitally blind and sighted individuals acquire similar world representations, blind individuals compensate for behavioral shortcomings through neurofunctional and multisensory reorganization. These reorganizations may indicate etiological explanations for their PaSZ. Second, we demonstrate that visuo-cognitive impairments are fundamental for the development of schizophrenia. Deteriorated visual information acquisition and processing contribute to higher-order cognitive dysfunctions and subsequently to schizophrenic symptoms. Finally, we provide different specific therapeutic recommendations for individuals who suffer from visual impairments (who never developed “normal” vision) and individuals who suffer from visual deterioration (who previously had “normal” visual skills). Rather than categorizing individuals as “normal” and “mentally disordered,” the PaSZ model uses a continuous scale to represent psychiatrically relevant human behavior. This not only provides a scientific basis for more fine-grained diagnostic assessments, earlier detection, and more appropriate therapeutic assignments, but it also outlines a trajectory for unraveling the causes of abnormal psychotic human self- and world-perception.
