Actor-Observer Effect01:23

Actor-Observer Effect

427
The actor-observer effect, a cognitive bias closely linked to the fundamental attribution error, refers to the tendency for individuals to attribute their behavior to external, situational factors while explaining others’ behavior in terms of internal, dispositional traits. This asymmetry in attribution significantly influences social perception and judgment.Cognitive Mechanisms Behind the EffectTwo primary psychological mechanisms contribute to the actor-observer effect: differences in...

Factors Affecting Perception01:25

Factors Affecting Perception

2.9K
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...

Empathy

10.2K
Some researchers suggest that altruism operates on empathy. Empathy is the capacity to understand another person’s perspective, to feel what he or she feels. An empathetic person makes an emotional connection with others and feels compelled to help (Batson, 1991). Empathy can be expressed in several ways, including cognitive, affective, and motor.

Nonconscious Mimicry

Nonconscious mimicry occurs when individuals alter their mannerisms to match the behaviors and expressions of those nearby, without intention.

Facial Feedback Hypothesis01:24

Facial Feedback Hypothesis

695
Charles Darwin proposed that facial expressions are an evolutionary adaptation for communication. He argued that these expressions are not influenced by culture but are universal across species. For example, a snarling expression with exposed teeth signals a threat in many animals, including humans. Darwin also suggested that displaying an emotion can intensify the feeling. Smiling, for example, could enhance one's sense of happiness. This idea laid the foundation for understanding the role...

Depth Perception and Spatial Vision01:15

Depth Perception and Spatial Vision

2.2K
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.

Resumen

La oxitocina (OT) impacta la toma de perspectiva visual (VPT) de manera diferente según las demandas de la tarea. Deteriora la VPT explícita pero mejora la VPT implícita cuando hay un agente humano presente, mostrando efectos matizados en el procesamiento del yo-otro.

Área de la Ciencia:

  • Neurociencia
  • Cognición Social
  • Psicología

Sus antecedentes:

  • La toma de perspectiva visual (VPT) es crucial para la cognición social.
  • La VPT explícita requiere la adopción deliberada de un punto de vista, mientras que la VPT implícita es incidental.
  • La oxitocina (OT) influye en el vínculo social, pero su papel en la VPT no está claro.

Objetivo del estudio:

  • Investigar los efectos de la oxitocina en la toma de perspectiva visual explícita e implícita.
  • Determinar si la oxitocina modula el procesamiento del yo-otro en diferentes contextos de VPT.

Principales métodos:

  • Un estudio doble ciego controlado con placebo con 79 participantes varones sanos.
  • Los participantes completaron tareas de VPT explícita e implícita en diversos contextos sociales (agente humano frente a objeto).
  • Se administró oxitocina o placebo por vía intranasal.

Principales resultados:

  • La oxitocina redujo la precisión en tareas de VPT explícita con conflicto de perspectiva, lo que indica una mayor interferencia egocéntrica.
  • La oxitocina mejoró la velocidad de respuesta y la precisión en tareas de VPT implícita con un agente humano.
  • Los hallazgos sugieren que los efectos de la oxitocina en la VPT dependen del contexto.

Conclusiones:

  • La administración de oxitocina modula diferencialmente el procesamiento del yo-otro en la toma de perspectiva visual.
  • La influencia del neuropéptido en la VPT no es una mejora o deterioro general, sino que varía con las demandas de la tarea y las señales sociales.
  • Los resultados proporcionan evidencia conductual de los efectos específicos del contexto de la oxitocina en la cognición social.
