Barriers to Effective Communication II01:21

Barriers to Effective Communication II

3.6K
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...

Barriers to Effective Communication I

8.8K
A communication barrier is any distortion or interruption during a conversation, resulting in miscommunication of the message. A good communicator should know these barriers and continuously check for the listener's understanding by obtaining feedback.
Communication barriers include the following:
Physiological barriers: They are limitations caused by a person's health condition or disability, such as hearing loss, poor eyesight, illness, or unconsciousness. An example to overcome this...

Cause and Effect01:53

Cause and Effect

10.9K
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?

Types of Selection01:46

Types of Selection

40.3K
Natural selection influences the frequencies of particular alleles and phenotypes within populations in several different ways. Primarily, natural selection can be directional, stabilizing, or disruptive. Directional selection favors one extreme trait and shifts the population towards that phenotype while selecting against individuals displaying alternate traits. Stabilizing selection favors an intermediate trait with a narrow range of variation. Deviation from the optimal phenotype towards an...

Communication01:03

Communication

7.7K
Communication between two animals occurs when one animal transmits an information signal that causes a change in the animal that receives the information. Organisms communicate with one another in a host of different ways. Signals can be auditory, chemical, visual, tactile, or a combination of these. Communication is a critical behavioral adaptation that promotes survival, growth, and reproduction.

The Anchoring-and-Adjustment Heuristic01:25

The Anchoring-and-Adjustment Heuristic

7.2K
In order to make good decisions, we use our knowledge and our reasoning. Often, this knowledge and reasoning is sound and solid. However, sometimes, we are swayed by biases or by others manipulating a situation. For example, let’s say you and three friends wanted to rent a house and had a combined target budget of $1,600. The realtor shows you only very run-down houses for $1,600 and then shows you a very nice house for $2,000. Might you ask each person to pay more in rent to get the...

Area of Science:

  • Neuroscience
  • Computational Neuroscience
  • Cognitive Neuroscience

Background:

  • Synchronous neural oscillations are linked to perception and cognition.
  • The 'communication through coherence' (CTC) hypothesis proposes oscillations facilitate brain communication.
  • The precise causal role and mechanisms of CTC remain unclear.

Purpose of the Study:

  • To computationally investigate a specific CTC mechanism for selective attention.
  • To explore the role of alpha and gamma band oscillations in thalamocortical communication.
  • To examine the influence of top-down control signals on attention via pulvinar nucleus.

Main Methods:

  • Developed a computational model of the proposed CTC mechanism.
  • Simulated alpha oscillations from the pulvinar nucleus organizing cortical gamma oscillations.
  • Analyzed the model's parameter space to determine its scope and limitations.

Main Results:

  • The CTC mechanism can explain some aspects of top-down and bottom-up attentional selection.
  • Identified limitations in the CTC mechanism's ability to fully account for attentional effects.
  • Computational results suggest alternative or complementary mechanisms may be involved.

Conclusions:

  • The proposed CTC mechanism, involving pulvinar-generated alpha oscillations, partially explains selective attention.
  • Limitations suggest that neural coherence might be a consequence, rather than a cause, of communication.
  • Further research is needed to elucidate the interplay between coherence and communication in attention.
