Anatomy of the Ear01:16

Anatomy of the Ear

11.8K
Auditory sensation, commonly called hearing, involves the transformation of sonic waves into neural impulses facilitated by the structures of the auditory organ. The prominent, flesh-like structure on the side of the head, called the auricle, directs sound waves towards the auditory canal. The auricle is often mislabeled as the pinna, a term more aligned with mobile structures like a feline's external ear. The auditory canal penetrates the cranium via the external auditory meatus of the...

Impact of Individuals on Individuals

403
Human behavior is intricately shaped by social influences that arise from interactions with others in diverse contexts. These influences not only mold beliefs and attitudes but also drive the regulation of behaviors through both direct communication and observational learning. The study of these processes falls within the domain of social psychology, which seeks to understand how individuals are affected by and affect those around them.Mechanisms of Social InfluenceDirect social influence...

Impact of Groups on Individuals

363
Groups play a fundamental role in shaping individual behavior, as they establish norms that guide interactions and decision-making. Social psychology examines how individuals conform to group expectations, often adjusting their attitudes and actions to align with group norms. These norms can be formal, such as workplace policies, or informal, such as unspoken social expectations within a fraternity.Conformity and Social InfluenceConformity arises when individuals modify their behaviors or...

Impact of Individuals on a Group

332
In social psychology, the interplay between individuals and groups is a central concern, particularly regarding how individual actions and characteristics influence group processes and outcomes. While much research emphasizes the group's power in shaping individual behavior, it is equally significant to understand how individuals contribute to the functioning, development, and success of groups.Individual Roles in Group Productivity and Decision-MakingIndividuals are not passive participants in...

Adler's Individual Psychology

2.4K
Alfred Adler, a prominent figure in psychology, founded the school of individual psychology. In contrast to Freud's emphasis on sexual or aggressive motives, Adler suggested that individuals are primarily motivated by their purposes and goals. He believed that people strive for perfection rather than pleasure. Adler argued that individuals could creatively act upon their genetic inheritance and environmental experiences to shape their own lives, emphasizing conscious motivation over...

Dosage Regimen: Individualization01:24

Dosage Regimen: Individualization

187
Individualization in dosing regimens is the customization of medication doses for individual patients. Its necessity arises from the goal of maximizing therapeutic benefits while minimizing risks. This approach is pivotal because human responses to drugs can vary widely; what is effective for one person may be inadequate or excessive for another. Interpatient (intersubject) variability refers to differences in drug responses between individuals, while intrapatient (intrasubject) variability...

Summary

Bilateral cochlear implants may hinder singing. Singing pitch accuracy decreased when using both implants compared to the better ear alone in adult users.

Area of Science:

  • Auditory perception and speech
  • Prosthetic device efficacy

Background:

  • Individuals with bilateral cochlear implants (CIs) often perceive different pitches between ears.
  • This pitch disparity may negatively impact vocalization, specifically singing abilities.

Purpose of the Study:

  • To investigate the effect of bilateral cochlear implants on singing pitch accuracy.
  • To determine if using both CIs simultaneously is detrimental to singing compared to unilateral use.

Main Methods:

  • Ten adult users with bilateral CIs (pre- or post-lingual deafness) participated.
  • Participants sang "Happy Birthday" while using their left CI, right CI, both CIs, or no CI.

Main Results:

  • Singing pitch contour accuracy was significantly reduced when using both CIs simultaneously.
  • Performance with both CIs was worse than with the better-hearing ear alone.

Conclusions:

  • Bilateral cochlear implants can present challenges for singing pitch control.
  • Optimizing CI use for musical tasks like singing may require considering individual device performance and ear differences.
