Subconsciousness and No Awareness01:15

Subconsciousness and No Awareness

387
The concept of subconscious awareness refers to the processing of information below the level of conscious thought, which significantly influences both behaviors and decisions. It is also known as waking subconscious awareness. This complex level of cognition operates without the direct awareness of the individual, facilitating rapid and simultaneous handling of multiple information streams.
An illustrative example of subconscious processing is its role in problem-solving. Often, individuals...

Subliminal Perception01:15

Subliminal Perception

374
Subliminal perception refers to the processing of sensory information that occurs below the level of conscious awareness. Researchers study subliminal perception by presenting a stimulus, such as a word or image, very quickly, typically around 50 milliseconds. This rapid presentation is often followed by another stimulus, such as a pattern of dots or lines, which blocks further mental processing of the initial stimulus. As a result, if participants cannot identify the initial stimulus better...

The Looking Glass Self01:28

The Looking Glass Self

29
The concept of the looking-glass self describes how an individual's self-concept is shaped by their perception of how others see them. This psychological theory, first introduced by sociologist Charles Horton Cooley in 1902, posits that self-identity emerges in a social context and is influenced by the judgments—real or imagined—of others.Research suggests that individuals frequently overestimate how positively others perceive them. This is particularly evident in physical...

Extrasensory Perception01:23

Extrasensory Perception

426
Extrasensory perception, or ESP, suggests the ability to perceive events beyond the conventional senses of sight, hearing, and touch. Parapsychologists, who research ESP and related psychic phenomena, categorize ESP into three main types: precognition, telepathy, and clairvoyance.
Precognition involves foreseeing future events, such as predicting an accident before it happens. An example of precognition could be someone dreaming about a specific event, like a car crash, which then occurs...

Freudian Psychology01:26

Freudian Psychology

1.0K
Sigmund Freud, an Austrian neurologist born in 1856, significantly influenced psychology through his exploration of the unconscious mind. His interest in patients suffering from hysteria and neurosis — conditions without apparent physical causes — led him to theorize the existence of an unconscious mind, a repository for feelings and urges beyond our awareness. Freud's innovative approach included techniques such as dream analysis, free association, and attention to slips of the...

Altered States of Awareness01:06

Altered States of Awareness

526
Altered states of consciousness represent significant deviations from one's normal mental state. These deviations can range from subtle changes in awareness to profound transformations in perception, thought processes, and sensory experiences. Altered states of consciousness can be triggered by various factors, including drug use, meditation, hypnosis, illness, or even intense fatigue.
The ingestion of substances like stimulants or hallucinogens leads to chemical alterations in the brain...

Area of Science:

  • Neuroscience
  • Cognitive Psychology
  • Human Motor Control

Background:

  • Sensory modality influences body representation for visually accessible body parts.
  • The representation of rarely viewed body parts remains less understood.
  • Investigating body representation for out-of-view targets is crucial for understanding spatial cognition.

Purpose of the Study:

  • To determine if exteroceptive, visually dependent body representations are used for rarely viewed body parts.
  • To explore the role of sensory cues (verbal vs. tactile) in encoding the position of unseen body regions.
  • To investigate the influence of sensorimotor processes on the spatial encoding of the vertex.

Main Methods:

  • Participants pointed to the vertex (top of the head) after verbal or tactile cues.
  • Peripheral gaze fixation was used to assess the type of body representation employed.
  • Pointing accuracy was analyzed based on gaze direction and cue modality.

Main Results:

  • Pointing errors were biased opposite to gaze direction, indicating a visually dependent exteroceptive representation.
  • Tactile cues led to greater pointing accuracy than verbal cues, suggesting sensorimotor enhancement.
  • Participants were more accurate in locating their own vertex than another person's.

Conclusions:

  • Rarely viewed body parts are spatially encoded using exteroceptive, vision-dependent representations.
  • Non-visual sensorimotor processes contribute to the construction of these body representations.
  • The brain actively constructs visual body representations even for areas not regularly seen.
