The Anchoring-and-Adjustment Heuristic01:25

The Anchoring-and-Adjustment Heuristic

7.7K
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...

Depth Perception and Spatial Vision01:15

Depth Perception and Spatial Vision

1.8K
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.

Visual Agnosia01:12

Visual Agnosia

899
Visual agnosia is a condition characterized by the inability to recognize visually presented objects despite having normal vision. For instance, a person with visual agnosia can describe the shape and color of an object but cannot identify or name it. This impairment does not affect their visual field, acuity, color vision, brightness discrimination, language, or memory. An example of this condition in a social setting is someone at a dinner party asking for "that silver thing with a round...

Association Areas of the Cortex01:21

Association Areas of the Cortex

8.7K
Association areas are regions of the cerebral cortex that do not have a specific sensory or motor function. Instead, they integrate and interpret information from various sources to enable higher cognitive processes such as memory, learning, and decision-making. Some key association areas include the following:
Prefrontal Association Area: This area is located in the frontal lobe and is involved in planning, decision-making, and moderating social behavior. It connects with primary motor areas,...

Perceptual Constancy01:12

Perceptual Constancy

1.2K
Perceptual constancy is the ability to recognize that objects remain consistent and unchanged even when their appearance varies due to changes in sensory input. There are four main types of perceptual constancy: size constancy, shape constancy, color constancy, and brightness constancy.
Size constancy is the recognition that an object remains the same size, even when its image on the retina changes. For instance, a bus is perceived to be large enough to carry people, even if it looks tiny from...

Area of Science:

  • Cognitive Psychology
  • Visual Perception
  • Scene Understanding

Background:

  • Semantic information guides attention in scene viewing.
  • The precise mechanisms of this guidance are not fully understood.
  • Anchor objects may be key semantic associates for efficient search.

Purpose of the Study:

  • To test the hypothesis that anchor objects are essential for efficient target search in naturalistic scenes.
  • To investigate the role of anchor objects as predictive spatial cues.
  • To differentiate the function of anchor objects from general scene regularities and semantic associations.

Main Methods:

  • Adult participants completed a rapid serial visual presentation (RSVP) search task.
  • Experiments involved prime-target pairs with varying semantic relatedness and spatial congruence.
  • Object roles (prime/target) were manipulated to assess directionality of effects.

Main Results:

  • Semantically related objects facilitated target identification regardless of prime-target role.
  • Anchor objects, unlike unrelated objects, acted as predictive spatial cues.
  • The predictive spatial cueing effect of anchor objects was distinct from general scene regularities.

Conclusions:

  • Anchor objects represent a unique class of semantic associates.
  • They provide both "what" and "where" information about associated objects in a scene.
  • Their role in spatial prediction extends beyond general scene knowledge and simple semantic links.
