Scene inversion impairs activation of scene-object semantic bias

Area of Science:

• Cognitive Psychology
• Neuroscience
• Visual Perception

Background:

• Scene perception relies on semantic inferences to parse complex visual information.
• Top-down influences, like scene gist, create biases for object recognition and attention.
• Factors driving scene-object bias activation remain under-investigated.

Purpose of the Study:

• To investigate the role of global scene semantics in activating scene-object bias.
• To compare the effects of scene inversion on bias activation at different hierarchical levels.

Main Methods:

• Briefly presented upright and inverted scenes were used to compare response bias.
• Behavioral measures assessed the speed and nature of bias activation.

Main Results:

• Scene inversion significantly delayed the activation of scene-object bias.
• Scene inversion differentially affected superordinate-level and basic-level bias.
• Superordinate-level bias activated earlier and more robustly than basic-level bias.

Conclusions:

• Global scene semantics play a critical role in activating scene-object bias.
• Gist-activated scene-object bias is a key top-down mechanism in visual cognition.
• Hierarchical processing differences influence the speed and impact of scene-object bias.
