The Stanford Prison Experiment03:20

The Stanford Prison Experiment

22.4K
The famous and controversial Stanford Prison Experiment, conducted by social psychologist Philip Zimbardo and his colleagues at Stanford University, demonstrated the power of social roles, social norms, and scripts.

Obedience01:08

Obedience

26.2K
According to obedience research, we may harm others under the forceful pressures of an authority figure (Milgram, 1974). How about if the inappropriate orders were delivered with less force? The increasing interdependence between nurses and physicians compelled Hofling and his colleagues to explore nurses’ reactions to a potentially harmful medical request made by the perceived authority figure, the doctor (Hofling, Brotzman, Dalrymple, Graves, & Pierce, 1966). In this situation,...

Milgram's Obedience to Authority

6.0K
Obedience to authority is classically demonstrated in a more famous series of social psychology experiments performed by Stanley Milgram. He was a social psychology professor at Yale who was influenced by the trial of Adolf Eichmann, a Nazi war criminal. Eichmann’s defense for the atrocities he committed was that he was “just following orders.”

Social Proof00:52

Social Proof

24.9K
Social proof is a form of persuasion based on comparison and conformity. People compare their behavior and actions to what others are doing and will change to conform to do what their peers do.

Social Loafing01:37

Social Loafing

29.3K
Another way in which a group presence can affect performance is social loafing—the exertion of less effort by a person working together with a group. Social loafing occurs when our individual performance cannot be evaluated separately from the group. Thus, group performance declines on easy tasks (Karau & Williams, 1993). Essentially individual group members loaf and let other group members pick up the slack. Because each individual’s efforts cannot be evaluated,...

Deindividuation00:57

Deindividuation

22.4K
Deindividuation is a form of social influence on an individual’s behavior such that the individual engages in unusual or non-normal behavior while in a group setting. Why? Because in these group settings, the individual no longer sees themselves as an individual anymore, disinhibiting their behavior and personal restraint.

Área de la Ciencia:

  • Paleontología; Neurobiología; Ciencia de los Artrópodos

Sus antecedentes:

  • Los sistemas nerviosos fosilizados ofrecen información sobre la evolución de los euartrópodos.
  • El análisis comparativo con especies existentes es crucial para la interpretación de datos fósiles.
  • Estudios previos han aplicado métodos similares a taxones del Cámbrico.

Objetivo del estudio:

  • Investigar la identidad de un sistema nervioso de euartrópodos fosilizados.
  • Validar la metodología de comparación de sistemas nerviosos fósiles con especies existentes.
  • Abordar afirmaciones específicas sobre la identificación de características del sistema nervioso de arácnidos.

Principales métodos:

  • Análisis comparativo de sistemas nerviosos de euartrópodos fosilizados con especies existentes.
  • Examen detallado de características neuroanatómicas.
  • Análisis filogenético que incorpora datos de los sistemas neural y respiratorio.

Principales resultados:

  • La identidad del sistema nervioso de euartrópodos fosilizados fue investigada.
  • Se invalidaron las afirmaciones de no identificación de características del sistema nervioso de arácnidos existentes.
  • El estudio demostró la utilidad de los caracteres neurales para comprender las relaciones de los artrópodos.

Conclusiones:

  • La metodología utilizada es eficaz para la identificación de sistemas nerviosos fosilizados.
  • El estudio identificó con éxito características clave del sistema nervioso de los arácnidos.
  • Los caracteres neurales pueden contribuir a desambiguar las relaciones filogenéticas en los euartrópodos.
