“…Angular patterns elicit a larger response than do straight-line patterns (Moskowitz et al, 1974;Wu, Ito, Kuwabara, Sugata, & Kida, 1994). An oblique effect in the angular patterns might exist, as was demonstrated for grating patterns (Frost & Kaminer, 1975;Maffei & Campbell, 1970;May & Cullen, 1979;Yoshida et al, 1975). From these findings, it is predicted that the diamond evokes a larger response than the square, because the angular parts of the diamond are located in the horizontal and vertical directions from its center, while those of the square are positioned obliquely.…”

“…Concerning the effect of spatial orientation upon VEPs, several studies have confirmed the "oblique effect", mainly using grating patterns (Frost & Kaminer, 1975;Maffei & Campbell, 1970;May & Cullen, 1979;Yoshida, Iwahara, & Nagamura, 1975). Appelle (1972) referred to the effect as "a small but consistent superiority in performance when visual stimuli are horizontal or vertical, as opposed to oblique" (p. 266).…”

Five outlined geometric figures of equal contour length were presented monocularly below the fixation point (FP); an upright equilateral triangle (upright triangle), an inverted equilateral triangle (inverted triangle), an upright square (square), a 45°‐tilted square (diamond) and a circle. The angular separation between FP and the top of the figures was held constant. Transient visual evoked potentials (VEPs) were recorded monopolarly from inion, 4, 7, 10 cm above it (l, l4, l7, l10) and Cz for ten subjects. The grand‐averaged subtracted waves were obtained between the figure and blank (control) conditions. N1 (mean peak latency: 155 ms) and P2 (240 ms) waves were identified. ANOVAs were conducted for the latency and amplitude values. Main results were as follows: On the N1 amplitude at l4 and l, the upright triangle, inverted triangle and diamond figures evoked significantly larger responses than did the square and the circle. However, no significant difference was found among the former three figures. These findings on the N1 amplitude suggest that the effect of a triangle is orientation‐free and that of a square is orientation‐bound.

“…Proverbio et al (2002) reported orientation-related differences in P1 and P3 components, vertical elicited larger amplitudes than oblique stimuli (they did not look at horizontal stimuli). A study conducted by Yoshida et al (1975) found differences in N1-P2 peak-to-peak amplitude, cardinal stimuli evoked larger responses than oblique stimuli. They obtained waveforms similar to ours using circular black and white gratings as stimuli, a P1-N1-P2 sequence was elicited with peak latencies of 110–120, 180–190, and 270–280 ms, respectively.…”

“…Using event-related potentials (ERP) unequal responses have been obtained to cardinal and oblique orientations in steady state potentials (Maffei and Campbell, 1970; May et al, 1979; Skrandies, 1984; Moskowitz and Sokol, 1985); transient ERPs (Yoshida et al, 1975; Arakawa et al, 2000; Proverbio et al, 2002), and MEG (Koelewijn et al, 2011). …”

We investigated whether visual orientation anisotropies (known as oblique effect) exist in non-attended visual changes using event-related potentials (ERP). We recorded visual mismatch negativity (vMMN) which signals violation of sequential regularities. In the visual periphery unattended, task-irrelevant Gábor patches were displayed in an oddball sequence while subjects performed a tracking task in the central field. A moderate change (50°) in the orientation of stimuli revealed no consistent change-related components. However, we found orientation-related differences around 170 ms in occipito-temporal areas in the amplitude of the ERPs evoked by standard stimuli. In a supplementary experiment we determined the amount of orientation difference that is needed for change detection in an active, attended paradigm. Results exhibited the classical oblique effect; subjects detected 10° deviations from cardinal directions, while threshold from oblique directions was 17°. These results provide evidence that perception of change could be accomplished at significantly smaller thresholds, than what elicits vMMN. In Experiment 2 we increased the orientation change to 90°. Deviant-minus-standard difference was negative in occipito-parietal areas, between 120 and 200 ms after stimulus onset. VMMNs to changes from cardinal angles were larger and more sustained than vMMNs evoked by changes from oblique angles. Changes from cardinal orientations represent a more detectable signal for the automatic change detection system than changes from oblique angles, thus increased vMMN to these “larger” deviances might be considered a variant of the magnitude of deviance effect rarely observed in vMMN studies.

“…In humans, the evidence of a neurophysiological oblique effect bias consists of YEP amplitude and latency (Sokol, Moskowitz, & Hansen, 1989;Zemon,Gutowski, & Horton 1983;Maffei & Campbell, 1970;Yoshida, Iwahara, & Nagamura, 1975) as well as fMRI neuroimaging magnitude (Furmanski and Engel, 2000). Since threshold for a particular stimulus pattern is thought to be directly associated with the number of neurons tuned to that pattern (Essock, Krebs, & Prather, 1997;Anzai, Bearse, & Freeman, 1995 ), this numerical anisotropy in the tuning preferences of neurons would explain the presence of the behavioral oblique effect.…”
