    Visual search for hidden shapes is slower when they are oblique, not horizontal/vertical. This effect occurs because the brain processes oblique visual information less efficiently, impacting visual search performance.

    Area of Science:

    • Psychology
    • Visual Perception
    • Cognitive Science

    Background:

    • The oblique effect describes the finding that human visual perception performs better with horizontal and vertical lines than with oblique lines.
    • Understanding the oblique effect is crucial for fields like visual display design and image analysis.

    Purpose of the Study:

    • To investigate the oblique effect using an embedded-figures task.
    • To quantify how the alignment of contextual contours affects search times for both oblique and orthogonal targets.

    Main Methods:

    • Systematically varied the percentage of contextual contours aligned with hidden forms (horizontal/vertical vs. oblique).
    • Measured search times and variance in an embedded-figures task.
    • Compared performance for locating oblique targets versus horizontal/vertical targets.

    Main Results:

    • Search times increased with higher percentages of aligned contextual contours for both orientations.
    • Locating oblique targets took significantly longer than horizontal/vertical targets (p < 0.05).
    • Search time variance was significantly greater for oblique targets (p < 0.025).

    Conclusions:

    • Organizational principles of visual search apply similarly to oblique and orthogonal orientations.
    • Perceptual processing of oblique orientations is less efficient, contributing to the oblique effect.
    • The findings relate to dual processes of extraction and synthesis in visual search.
