Factors Affecting Perception01:25

Factors Affecting Perception

1.6K
Perception is influenced by perceptual set, context, motivation, and emotion. Perceptual set, or perceptual expectancy, refers to the tendency to perceive things in a particular way, influenced by previous experiences and expectations. This phenomenon affects the interpretation of stimuli, creating a set of mental tendencies and assumptions that impact sensory perceptions of sound, taste, touch, and sight.
An illustrative example of a perceptual set is the scenario where an airline pilot told...

Hindsight Biases01:12

Hindsight Biases

3.4K
Hindsight bias leads you to believe that the event you just experienced was predictable, even though it really wasn’t. In other words, you knew all along that things would turn out the way they did. Can you relate this to the phrase "Hindsight is 20/20" now?

Depth Perception and Spatial Vision01:15

Depth Perception and Spatial Vision

668
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.

Perceptual Constancy01:12

Perceptual Constancy

397
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...

Stereotypes, Prejudice, and Discrimination02:55

Stereotypes, Prejudice, and Discrimination

90.2K
Humans are very diverse and although we share many similarities, we also have many differences. The social groups we belong to help form our identities (Tajfel, 1974). These differences may be difficult for some people to reconcile, which may lead to prejudice toward people who are different. Prejudice is a negative attitude and feeling toward an individual based solely on one’s membership in a particular social group (Allport, 1954; Brown, 2010). Prejudice is common against people who...

Summary

Visual biases near handheld tools occur even without active use, suggesting tools capture attention through their presence, not just incorporation into the body schema.

Area of Science:

  • Cognitive Psychology
  • Neuroscience
  • Human-Computer Interaction

Background:

  • Visual perception is influenced by the presence of handheld tools.
  • This phenomenon may stem from tools being integrated into the body schema through active use.
  • Alternatively, tools might gain visual salience, leading to attentional prioritization independent of body schema integration.

Purpose of the Study:

  • To investigate the mechanisms behind visual biases in the space surrounding handheld tools.
  • To differentiate between body schema incorporation and visual salience as explanations for these biases.
  • To determine if active tool use is necessary for near-tool visual biases.

Main Methods:

  • Two experiments involving a target detection task were conducted.
  • Participants detected targets appearing near or far from a handheld tool.
  • Experiment 1 used a rake; Experiment 2 used a novel magnetic tool, with conditions varying tool use and holding.

Main Results:

  • Near-tool visual bias was observed in Experiment 1, irrespective of prior tool use, but not when participants only viewed the tool.
  • In Experiment 2, participants holding a magnetic tool showed a near-tool bias even without using it.
  • Active use of the tool was not required to elicit the visual bias.

Conclusions:

  • The findings suggest that active tool use is not essential for creating visual biases in peri-tool space.
  • Visual salience alone is insufficient to explain these biases; the act of holding the tool appears crucial.
  • These results challenge the sole reliance on body schema incorporation and highlight the role of tool presence in attentional prioritization.
