Depth Perception and Spatial Vision01:15

Depth Perception and Spatial Vision

2.7K
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.

Inertial Frames of Reference

10.0K
Newton’s first law is usually considered to be a statement about reference frames. It provides a method for identifying a special type of reference frame: the inertial reference frame. In principle, we can make the net force on a body zero. If its velocity relative to a given frame is constant, then that frame is said to be inertial. So, by definition, an inertial reference frame is a reference frame where Newton's first law holds valid. Newton's first law applies to objects with...

Non-inertial Frames of Reference01:27

Non-inertial Frames of Reference

8.6K
A reference frame accelerating or decelerating relative to an inertial frame is a non-inertial frame. To help understand this, consider what taking off in an airplane, turning a corner in a car, riding a merry-go-round, and the circular motion of a tropical cyclone all have in common. All these systems are accelerating, decelerating, or rotating relative to the Earth; hence, they all are non-inertial frames. All these systems exhibit inertial forces, which merely seem to arise from motion,...

Framing Effects

8.1K
Information is everywhere and its presentation—such as how and when items are presented—can impact our perceptions and decisions surrounding the info. This broad concept umbrellas framing effects—influences that occur due to the way information is framed in its appearance, whether it’s purely the order or the specific wording of a message. Let’s take a look at numerous ways in which two versions of something can objectively say the same thing, yet we respond in...

Summary

Visual search priming uses both space-based and object-centered memory. Target locations are coded spatiotopically and object-centrically, while distractors use object-centered coding.

Area of Science:

  • Cognitive Psychology
  • Neuroscience
  • Visual Perception

Background:

  • Positional priming influences visual search efficiency.
  • Understanding the reference frames for visual working memory is crucial.

Purpose of the Study:

  • Investigate representations underlying positional priming in visual pop-out search.
  • Differentiate between retinotopic, spatiotopic, and object-centered priming representations.
  • Examine how trial-to-trial sequence predictability affects these representations.

Main Methods:

  • Presented three search items (target and two distractors) in invariant or random sequences.
  • Measured reaction times (RTs) for target facilitation and distractor inhibition.
  • Analyzed priming effects across different experimental conditions.

Main Results:

  • Target locations were coded using both spatiotopic and object-centered representations.
  • Distractor locations were consistently maintained within an object-centered reference frame.
  • Cross-trial sequence predictability modulated the use of space-based versus object-based representations.

Conclusions:

  • Positional short-term memory for targets integrates spatiotopic and object-centered information.
  • Distractor information is primarily processed via an object-centered frame.
  • Uncertainty in item displacement influences the flexibility of reference frame selection in visual working memory.
