Neurotransmitters01:31

Neurotransmitters

2.9K
Neurotransmitters are essential chemical messengers within the nervous system, facilitating the communication between neurons. These chemical messengers, varying in function and effect, are critical for sustaining various aspects of neurological health and emotional well-being.

Causes of Social Behavior II: Cognitive Processes

233
Cognitive processes affect social behavior by guiding how individuals perceive, interpret, and respond to social stimuli. These mental processes enable individuals to assess others' behaviors, attribute causes to their actions, and form expectations based on past experiences.Causes of Behavior and Social JudgmentsIndividuals determine the causes of others' behaviors by distinguishing between personal traits and external circumstances. For example, if a friend frequently arrives late, an...

Therapeutic Communication01:30

Therapeutic Communication

9.0K
Communication is a lifelong learning process. Through therapeutic communication, nurses can collect relevant assessment data, provide education and counseling, and interact during nursing interventions. Sending and receiving messages occur through verbal and nonverbal communication techniques and can happen separately or simultaneously.
Verbal communication depends on language or a prescribed way of using words so that people can share information effectively. The critical aspects of verbal...

Cognitivism

3.2K
Cognitive psychology emerged as a significant field in the mid-20th century. It focused on understanding humans' internal mental processes. This approach emphasizes how people perceive, remember, think, and solve problems—elements critical to human cognition.
Previously dominated by behaviorism, which prioritized observable behaviors and largely ignored mental processes, psychology transformed in the 1950s. Cognitive psychologists argue that understanding how we think and process...

The Influence of Affect on Cognition01:29

The Influence of Affect on Cognition

323
Positive affect significantly influences cognitive processes, including evaluation, memory, creativity, and social judgments. Compared to negative affect, positive emotional states promote more favorable interpretations of stimuli, cognitive flexibility, and heuristic processing. These effects highlight emotions' powerful role in shaping how individuals perceive, remember, and interact with the world.Influence on Evaluation and AttributionWhen individuals experience positive affect, they are...

Higher Mental Functions of the Brain: Language01:10

Higher Mental Functions of the Brain: Language

3.9K
Language is a system of communication that allows the expression of thoughts, ideas, and feelings. The brain processes language in both hemispheres.
Language formation and comprehension take place in the dominant hemisphere. The dominant hemisphere is responsible for understanding the meaning of spoken, written, or sign language, as well as the ability to communicate. For most people, the left hemisphere is the dominant one. The right hemisphere, then, gives tone and emotional context to the...

Area of Science:

  • Neuroscience
  • Cognitive Science
  • Social Psychology

Background:

  • Oxytocin, a neuropeptide, is known to influence material resource sharing.
  • Human communication involves signal selection for meaning disambiguation and audience design.
  • The impact of oxytocin on knowledge sharing remains largely unexplored.

Purpose of the Study:

  • To investigate the effect of oxytocin on knowledge sharing through non-verbal communication.
  • To examine oxytocin's influence on referential quality and audience design in communication.
  • To understand how oxytocin modulates cognitive exploration in communicative behaviors.

Main Methods:

  • A randomized, double-blind, placebo-controlled experiment with 55 male participants.
  • Intranasal administration of oxytocin.
  • Participants produced novel non-verbal signals towards adult and child addressees in a live interactive setting.

Main Results:

  • Oxytocin administration led to the generation of signals with higher referential quality.
  • Participants receiving oxytocin rapidly adjusted communicative signals based on addressee understanding.
  • Oxytocin promoted more pervasive exploration of communicative behaviors and addressee models.

Conclusions:

  • Oxytocin influences knowledge sharing by enhancing signal clarity and audience-specific adjustments.
  • The findings suggest oxytocin promotes cognitive exploration, impacting intention conveyance and understanding of others.
  • Beyond prosocial drives, oxytocin modulates cognitive processes crucial for effective knowledge sharing.
