Perception01:28

Perception

572
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...

Depth Perception and Spatial Vision01:15

Depth Perception and Spatial Vision

900
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.

Piaget's Stage 1 of Cognitive Development01:14

Piaget's Stage 1 of Cognitive Development

778
The sensorimotor stage, the initial phase of Jean Piaget's theory of cognitive development, spans the first two years of a child's life. During this period, infants actively engage with their surroundings, building cognitive awareness through direct interaction with the world. This interaction is primarily based on sensory perception and motor actions, allowing infants to gradually understand basic physical properties and predict how objects interact within their environment.

Neuroplasticity01:01

Neuroplasticity

762
Neuroplasticity reflects the brain's remarkable capacity to adapt and evolve, responding dynamically to learning, experiences, or injury by reorganizing its neural circuitry. This reorganization involves creating new neural connections and refining old ones through a series of biological processes that contribute to the brain's lifelong development and adaptability.

Factors Affecting Perception01:25

Factors Affecting Perception

1.8K
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...

Schemas01:42

Schemas

12.0K
A schema is a mental construct consisting of a cluster or collection of related concepts (Bartlett, 1932). There are many different types of schemata, and they all have one thing in common: schemata are a method of organizing information that allows the brain to work more efficiently. When a schema is activated, the brain makes immediate assumptions about the person or object being observed.

Resumen
Este resumen es generado por máquina.

La adaptación sensoriomotriz es robusta para dirigir las manipulaciones de atención. Sin embargo, la atención influye indirectamente en el aprendizaje al definir señales contextuales, impactando la generalización de la memoria motora cuando cambian los estímulos atendidos.

Área de la Ciencia:

  • La neurociencia
  • Ciencias cognitivas
  • Control del motor

Sus antecedentes:

  • La adaptación sensoriomotora se basa en las señales de error para la calibración.
  • La atención es un modulador conocido de varios procesos de aprendizaje.

Objetivo del estudio:

  • Investigar la influencia de la atención en la adaptación sensoriomotora.
  • Determinar si la atención espacial o los recursos de atención afectan las tasas de aprendizaje.
  • Explorar los efectos indirectos de la atención en el aprendizaje motor.

Principales métodos:

  • Experimentos que manipulan la atención espacial hacia / lejos de la retroalimentación visual.
  • Paradigmas de doble tarea para evaluar la asignación de recursos de atención.
  • Análisis de las tasas de adaptación sensorimotora en diferentes condiciones de atención.

Principales resultados:

  • La atención espacial y la disponibilidad de recursos atencionales no afectaron las tasas de adaptación sensorimotora.
  • La adaptación se atenuó cuando los estímulos atendidos cambiaron entre ensayos.
  • Los cambios en los estímulos no supervisados no afectaron la adaptación.

Conclusiones:

  • La adaptación sensoriomotora es en gran medida independiente del control directo de la atención.
  • La atención visual da forma al contexto de aprendizaje mediante la definición de señales relevantes.
  • Los estímulos atendidos actúan como anclas contextuales, que influyen en la generalización de la memoria motora.
