Orthogonal Trajectories01:26

Orthogonal Trajectories

72
Orthogonal trajectories describe the geometric relationship between two families of curves that intersect each other at right angles. One illustrative case involves a family of parabolas that open sideways along the x-axis. These curves share a common shape but differ by a scaling parameter, resulting in a set of curves that all pass through the origin and widen at different rates.Determining Orthogonal TrajectoriesTo identify the orthogonal trajectories for these parabolas, the first step...

Stereotypes, Prejudice, and Discrimination02:55

Stereotypes, Prejudice, and Discrimination

95.5K
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...

Subliminal Perception01:15

Subliminal Perception

810
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...

Factors Affecting Perception01:25

Factors Affecting Perception

2.8K
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...

Perception01:28

Perception

1.2K
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...

Gestalt Principles of Perception01:21

Gestalt Principles of Perception

1.3K
Gestalt principles provide a framework for understanding how humans perceive objects as unified wholes within their context. These principles are essential in explaining the cognitive processes that make sense of complex visual stimuli by organizing them into coherent groups. One fundamental principle is proximity, which posits that objects located close to each other are perceived as a collective group. For instance, when dots are positioned near one another, the visual system interprets them...

Summary

Newborns show a preference for objects moving towards them, indicating an innate ability to perceive their surroundings. This early visual tracking is crucial for developing self-awareness and interaction skills.

Area of Science:

  • Developmental Psychology
  • Cognitive Neuroscience
  • Infant Perception

Background:

  • The ability to track moving objects is vital for human interaction.
  • Sensitivity to object trajectories may be present from birth, aiding communication and defense.
  • Previous research often focused on defensive reactions, potentially missing earlier perceptual abilities.

Purpose of the Study:

  • To investigate newborns' ability to discriminate visual motion trajectories.
  • To determine if infants prefer stimuli approaching their body versus receding or moving towards surrounding space.
  • To understand the foundational visual mechanisms present at birth for environmental awareness.

Main Methods:

  • Measured newborns' looking behavior in response to visual stimuli.
  • Presented stimuli with trajectories directed towards the infant's body versus away from it.
  • Compared responses to stimuli approaching the body versus the immediate surrounding space.

Main Results:

  • Newborns demonstrated a spontaneous visual preference for trajectories moving towards their body.
  • This preference was observed for both approaching versus receding motion.
  • Infants also preferred stimuli targeting the body over those targeting the peripersonal space.

Conclusions:

  • Human infants possess innate visual mechanisms for perceiving their presence and surroundings.
  • Newborns show an adaptive focus on their bodily self and the peripersonal space.
  • These findings suggest early-developed visual processing supports self-awareness and environmental interaction.
