Resumen
La adaptación sensoriomotora implícita recalibra el movimiento de forma inconsciente pero no altera consistentemente la confianza. Este estudio revela que, si bien la adaptación implícita afecta la conciencia motora, la confianza sensoriomotora puede depender de mecanismos separados.
Área de la Ciencia:
- Neurociencia
- Control Motor
- Psicología Cognitiva
Sus antecedentes:
- La adaptación sensoriomotora es crucial para mantener la precisión del movimiento.
- La adaptación puede ser explícita (consciente) o implícita (inconsciente).
- La adaptación explícita reduce la confianza sensoriomotora, pero se desconoce el efecto de la adaptación implícita.
Objetivo del estudio:
- Investigar si la adaptación sensoriomotora implícita afecta la confianza en los juicios sensoriomotores.
- Determinar si la adaptación implícita influye en la conciencia motora (propiocepción).
Principales métodos:
- Los participantes realizaron movimientos de alcance con retroalimentación visual manipulada para inducir adaptación implícita (trayectoria de 'error-clamp').
- Se informó la confianza ajustando el tamaño del arco, con recompensas por informes precisos.
- Se utilizó análisis de Fourier para evaluar los cambios de adaptación y conciencia a lo largo de los ensayos.
Principales resultados:
- La adaptación sensoriomotora implícita fue robusta, como lo demuestran los cambios sinusoidales en las series temporales de alcance y reporte.
- La conciencia motora mostró cambios correspondientes, lo que indica que la adaptación influyó en los juicios propioceptivos.
- Los juicios de confianza no se vieron afectados consistentemente por la adaptación implícita.
Conclusiones:
- La adaptación sensoriomotora implícita, aunque inconsciente, puede sesgar los juicios de los resultados del movimiento debido a desajustes en las señales sensoriomotoras.
- La confianza sensoriomotora y la confianza en la conciencia propioceptiva parecen estar reguladas por mecanismos neuronales parcialmente distintos.

Not all intergroup interactions lead to negative outcomes. Sometimes, being in a group situation can improve performance. Social facilitation occurs when an individual performs better when an audience is watching than when the individual performs the behavior alone. This typically occurs when people are performing a task for which they are skilled.

213
According to George Herbert Mead, as children progress beyond the game stage, they develop a more comprehensive understanding of societal rules and norms. This cognitive and social development enables them to internalize the expectations of the broader community, refining their ability to regulate behavior.Consistent participation in organized activities is crucial in helping children recognize that their actions are not isolated but contribute to a more significant, interconnected group...

Self-monitoring is a central construct in understanding individual differences in self-presentation strategies across social contexts. It refers to how individuals observe, regulate, and control their expressive behavior and self-presentation following situational cues. Self-monitoring reflects a person's sensitivity to social appropriateness and willingness to adapt behavior to fit varying interpersonal demands.High vs. Low Self-Monitoring IndividualsIndividuals high in self-monitoring are...

People can go to great lengths to protect their self-image and present themselves in ways that they want others to see them. Sociologist Erving Goffman presented the idea that a person is like an actor on a stage. Calling his theory dramaturgy, Goffman believed that we use “impression management” to present ourselves to others as we hope to be perceived. Each situation is a new scene, and individuals perform different roles depending on who is present (Goffman, 1959). Think about...

01:21Self-Awareness and Its Effects
250
Self-awareness is a psychological state in which the individual becomes the focal point of their attention. This inward focus transforms the self into an object of contemplation and assessment, influencing how individuals perceive their actions and their alignment with personal and societal standards.Triggers and Contexts for Self-AwarenessSelf-awareness can be activated by external stimuli that make individuals visually or audibly aware of themselves, such as mirrors, cameras, or recordings.

01:23Actor-Observer Effect
301
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...
