Resumen

Los estudiantes universitarios sordos muestran una fuerte aversión a la inequidad, incluso con procedimientos justos. Sus cerebros señalan preferencias por la justicia, apoyando entornos educativos inclusivos para todos los estudiantes.

Área de la Ciencia:

Neurociencia Cognitiva; Psicología Social; Psicología Educativa

Sus antecedentes:

Las diferencias individuales en el procesamiento cognitivo pueden explicar la aversión inconsistente a la inequidad.
Los estudiantes universitarios sordos enfrentan barreras sistémicas que impactan la cognición y la interacción social.
Existe una comprensión limitada sobre la aversión a la inequidad entre los estudiantes sordos en contextos de justicia procesal.

Objetivo del estudio:

Investigar la aversión a la inequidad en estudiantes universitarios sordos bajo justicia procesal.
Explorar los correlatos neuronales de la percepción de la justicia en estudiantes sordos y oyentes.
Proporcionar datos empíricos sobre la cognición social de poblaciones especiales.

Principales métodos:

Se utilizó un juego del dictador modificado con potenciales relacionados con eventos (PE).
Se reclutaron 28 estudiantes universitarios sordos y 31 oyentes.
Se analizaron la satisfacción conductual y las respuestas electrofisiológicas (FRN y P300).

Principales resultados:

Todos los participantes prefirieron ofertas equitativas sobre las inequitativas.
Los estudiantes sordos mostraron respuestas neuronales intensificadas (FRN negativa) a ofertas inequitativas ventajosas y desventajosas en comparación con las equitativas.
Las ofertas equitativas provocaron respuestas P300 más positivas en los estudiantes sordos que las ofertas inequitativas.

Conclusiones:

Los estudiantes universitarios sordos demuestran una aversión significativa a la inequidad, priorizando las normas de justicia.
La justicia procesal no elimina la aversión a la inequidad en esta población.
Los hallazgos respaldan la necesidad de una mayor integración educativa y prácticas inclusivas en la educación superior.

Equity Theory

Equity Theory

Equity theory explains how our sense of fairness influences the dynamics of close relationships. Rooted in social psychology, the theory posits that individuals evaluate fairness by comparing the ratio of their contributions to the rewards they receive. Relationship satisfaction is highest when these ratios are perceived as balanced between partners, promoting mutual reciprocity and a sense of justice.Equity vs. Equality in RelationshipsEquity is distinct from equality. Fairness does not...

Barriers to Effective Communication II

Barriers to Effective Communication II

The barriers to effective communication also include cultural barriers, semantic barriers, gender barriers, and time constraints.
Cultural barriers:
Differences in values, beliefs, religion, knowledge, and tradition can significantly impact communication. Awareness of nonverbal cues is critical, especially when conversing with a patient from a different culture. What appears appropriate in one culture may be inappropriate in another.
Semantic barriers:
As a result of their tendency to use...

Surveys

Surveys

Often, psychologists develop surveys as a means of gathering data. Surveys are lists of questions to be answered by research participants, and can be delivered as paper-and-pencil questionnaires, administered electronically, or conducted verbally. Generally, the survey itself can be completed in a short time, and the ease of administering a survey makes it easy to collect data from a large number of people.

Compensation Mechanisms

Compensation Mechanisms

The human body employs intricate mechanisms to counteract changes in blood pH, preventing conditions like acidosis (pH < 7.35) and alkalosis (pH > 7.45). These compensatory responses aim to restore normal arterial blood pH by engaging respiratory or renal systems, depending on the source of the imbalance.
Respiratory Compensation
This mechanism addresses metabolic-induced pH imbalances by adjusting breathing rates. Respiratory compensation begins within minutes of detecting a pH...

Blind Procedures

Blind Procedures

Ideally, the people who observe and record the children’s behavior are unaware of who was assigned to the experimental or control group, in order to control for experimenter bias. Experimenter bias refers to the possibility that a researcher’s expectations might skew the results of the study. Remember, conducting an experiment requires a lot of planning, and the people involved in the research project have a vested interest in supporting their hypotheses. If the observers knew which...

Ethics in Research

Ethics in Research

Today, scientists agree that good research is ethical in nature and is guided by a basic respect for human dignity and safety. However, this has not always been the case. Modern researchers must demonstrate that the research they perform is ethically sound.
