Factors Affecting Perception

2.6K
Perception is influenced by perceptual set, context, motivation, and emotion.

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...

Assessment of the Gastrointestinal System II: Health Perception Pattern

Assessing the gastrointestinal (GI) system is a complex process that begins with collecting subjective data. This data, collected through patient interviews, provides crucial insights into the patient's health history, perception patterns, and lifestyle habits, all contributing significantly to GI health.
Health Perception Patterns
Health perception patterns offer valuable insights into a patient's lifestyle habits and how they may impact their GI health. These patterns include:

A variety of factors influence a person's health and well-being.
For instance, risk factors are connected to illness,...

An illness is a response to a disease in which the person's level of functioning is changed compared with a previous level. The general classification of illness includes acute and chronic.
Acute illness is severe...

Models of Health Promotion and Illness Prevention II

2.0K
The person's health status fluctuates continually, varying from being in good health to becoming ill and returning to being healthy. To understand the concept of illness prevention, there are two models. First, the health-illness continuum model is a graphic representation of an individual's wellness. It states that a person is considered healthy in the absence of physical disease and the presence of good emotional health.
The agent-host-environment model states that disease results...

Área de la Ciencia:

  • Psicología; Nefrología; Medicina Psicosomática

Sus antecedentes:

  • La percepción de los síntomas es subjetiva y está influenciada por factores biopsicosociales.
  • El Paradigma de Afecto y Síntomas (PAS) se utiliza para estudiar las influencias emocionales en la percepción de los síntomas.

Objetivo del estudio:

  • Investigar si la inducción de afecto negativo influye en la percepción de los síntomas en pacientes con enfermedad renal crónica no dialítica (ERCND) y controles sanos.
  • Examinar la asociación entre el efecto PAS y la carga de síntomas en pacientes con ERCND.

Principales métodos:

  • Los participantes vieron series de imágenes positivas, negativas y neutras.
  • Se calificaron los niveles de síntomas, el afecto y la excitación después de cada serie.
  • Se analizó la asociación del efecto PAS con la carga de síntomas a 6 y 12 meses en el grupo de ERCND.

Principales resultados:

  • Las imágenes negativas aumentaron el afecto negativo y la excitación en ambos grupos.
  • Los niveles de síntomas fueron más altos después de imágenes negativas en comparación con imágenes positivas/neutras, con respuestas comparables.
  • El efecto PAS predijo la carga de síntomas a 6 meses en pacientes con ERCND.

Conclusiones:

  • La inducción de afecto negativo aumenta demostrablemente los niveles de síntomas en enfermedades crónicas como la ERC.
  • Los hallazgos respaldan el modelo de procesamiento predictivo de la percepción de síntomas.
  • Las dificultades para identificar sentimientos moderaron los niveles de síntomas en el grupo de ERC.
