The Anchoring-and-Adjustment Heuristic01:25

The Anchoring-and-Adjustment Heuristic

7.3K
In order to make good decisions, we use our knowledge and our reasoning. Often, this knowledge and reasoning is sound and solid. However, sometimes, we are swayed by biases or by others manipulating a situation. For example, let’s say you and three friends wanted to rent a house and had a combined target budget of $1,600. The realtor shows you only very run-down houses for $1,600 and then shows you a very nice house for $2,000. Might you ask each person to pay more in rent to get the...

Perception

529
Perception is a fundamental psychological process that enables individuals to organize, interpret, and consciously experience sensory information. This process is crucial for understanding and interacting with the world around us. It includes both bottom-up and top-down processing, each playing a distinct role in how we perceive our environment.
Bottom-up processing begins at the sensory level, where receptors detect external environmental stimuli. These could include the tactile sensation of...

Depth Perception and Spatial Vision01:15

Depth Perception and Spatial Vision

787
Depth perception is the ability to perceive objects three-dimensionally. It relies on two types of cues: binocular and monocular. Binocular cues depend on the combination of images from both eyes and how the eyes work together. Since the eyes are in slightly different positions, each eye captures a slightly different image. This disparity between images, known as binocular disparity, helps the brain interpret depth. When the brain compares these images, it determines the distance to an object.

Area of Science:

  • Cognitive Psychology
  • Neuroscience
  • Visual Perception

Background:

  • Traditional theories suggest attention relies on exact target features in memory.
  • Recent evidence indicates attentional guidance is more flexible than previously thought.

Purpose of the Study:

  • To propose a new model of attentional guidance based on a 'good-enough' principle.
  • To explain how attention optimizes search efficiency and speed-accuracy-effort trade-offs.

Main Methods:

  • Integration of existing evidence on attentional guidance.
  • Theoretical modeling of visual search processes.

Main Results:

  • Attentional guidance is not always based on veridical target features.
  • A 'good-enough' principle guides rapid localization of candidate objects.

Conclusions:

  • Flexible attentional guidance optimizes visual search by prioritizing speed and efficiency.
  • Candidate objects are further verified with precise information after initial localization.
