Superstición: una cuestión de sesgo, no de detectabilidad
1Department of Psychology, Arizona State University, Tempe, AZ 85281, USA.
Resumen
Las palomas pueden distinguir entre estímulos que cambian debido a sus acciones y aquellos que no lo hacen. Sus procesos de toma de decisiones en respuesta a estos cambios reflejan el comportamiento humano de detección de señales.
Área de la Ciencia:
- La cognición animal es la cognición animal.
- Neurociencia del comportamiento neurológico.
- Psicología Comparada y Psicología Comparada.
Sus antecedentes:
- Comprender cómo los animales procesan la información y toman decisiones es crucial para la ciencia cognitiva.
- Distinguir entre estímulos comportamentales contingentes e independientes es un aspecto fundamental del comportamiento adaptativo.
Objetivo del estudio:
- Investigar la capacidad de las palomas para discriminar entre los cambios de estímulo dependientes de sus acciones y los que ocurren de forma independiente.
- Para comparar el rendimiento de las palomas en una tarea de detección de señales con el de los observadores humanos.
Principales métodos:
- Las palomas fueron entrenadas en una tarea que requería que respondieran a cambios en los estímulos.
- Los cambios en el estímulo dependieron de las respuestas de picoteo de las palomas o ocurrieron de forma independiente.
- Los pagos por respuestas correctas e incorrectas fueron manipulados para evaluar el sesgo de respuesta.
Principales resultados:
- Las palomas discriminaban con precisión entre los cambios de estímulo dependientes del comportamiento y los independientes.
- Las palomas exhibieron un rendimiento preciso en la identificación de estímulos relevantes.
- Las variaciones en las estructuras de recompensa influyeron en el sesgo de respuesta de las palomas, similar a los patrones de detección de señales humanas.
Conclusiones:
- Las palomas demuestran habilidades cognitivas sofisticadas para diferenciar entre los cambios ambientales auto-generados y externos.
- Los hallazgos sugieren mecanismos conservados de detección de señales y toma de decisiones entre especies.
- Los modelos de palomas ofrecen valiosos conocimientos sobre los principios fundamentales de la percepción y el comportamiento.

Magical Thinking
Magical thinking encompasses the belief in assumptions that defy logical reasoning yet appear intuitively convincing. It is a common psychological phenomenon that persists across various cultural and individual contexts. While these assumptions contradict empirical evidence and scientific laws, they often serve meaningful psychological roles in promoting emotional resilience and a sense of control, especially under stress or uncertainty.Thought-Action Fusion and the Law of SimilarityA key...
Bias
Bias refers to any tendency that prevents a question from being considered unprejudiced. In research, bias occurs when one outcome or answer is selected or encouraged over others in sampling or testing. Bias can occur during any research phase, including study design, data collection, analysis, and publication.
In statistics, a sampling bias is created when a sample is collected from a population, and some members of the population are not as likely to be chosen as others (remember, each member...

Cause and Effect
While variables are sometimes correlated because one does cause the other, it could also be that some other factor, a confounding variable, is actually causing the systematic movement in our variables of interest. For instance, as sales in ice cream increase, so does the overall rate of crime. Is it possible that indulging in your favorite flavor of ice cream could send you on a crime spree? Or, after committing crime do you think you might decide to treat yourself to a cone?
Confirmation Biases
The confirmation bias is the tendency to focus on information that confirms our existing beliefs and ignore information that is inconsistent with our expectations. For example, if you think that your professor is not very nice, you notice all of the instances of rude behavior exhibited by the professor while ignoring the countless pleasant interactions he is involved in on a daily basis. Have you ever fallen prey to the confirmation bias, either as the source or target of such bias?
Fundamental Attribution Error
According to some social psychologists, people tend to overemphasize internal factors as explanations—or attributions—for the behavior of other people. They tend to assume that the behavior of another person is a trait of that person, and to underestimate the power of the situation on the behavior of others. They tend to fail to recognize when the behavior of another is due to situational variables, and thus to the person’s state. This erroneous assumption is called the fundamental attribution...
Motivational Bias
Cognitive bias results from limitations in thinking and information processing, leading to systematic errors in judgment. Conversely, motivational bias stems from personal desires or emotions, causing distortions in perception to align with self-interest. Motivational bias influences how individuals perceive and attribute causes to events, often shaped by personal needs, goals, and self-esteem preservation. This bias can distort judgment, leading to inaccurate assessments of success, failure,...
