Higher Mental Functions of the Brain: Language

4.2K
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...

Family Therapy01:30

Family Therapy

814
Family therapy conceptualizes psychological challenges as arising from dysfunctional interactions within the family unit, rather than as isolated issues within individuals. This approach seeks to address and transform the patterns of communication, roles, and relationships within families to promote healthier dynamics and emotional well-being for all members.

Strategic family therapy emphasizes resolving communication barriers and improving problem-solving abilities...

Interpersonal Psychotherapy01:25

Interpersonal Psychotherapy

599
Interpersonal psychotherapy (IPT) is a structured, time-limited therapeutic approach initially developed to treat depression. It integrates key concepts from psychodynamic, humanistic, and cognitive-behavioral therapies, making it a uniquely eclectic framework. The therapy is rooted in the interpersonal theories of Adolph Meyer and Harry Stack Sullivan, as well as John Bowlby's attachment theory, and focuses on the interplay between interpersonal relationships and emotional well-being.

Alzheimer's Disease: Treatment

1.2K
Alzheimer's Disease (AD), a neurodegenerative disorder, is pathologically identified by amyloid plaques and neurofibrillary tangles composed of tau protein. AD pharmacotherapy aims to manage cognitive symptoms, delay disease progression, and treat behavioral symptoms. The treatment is primarily symptomatic and palliative, with no definitive disease-modifying therapy available. Cholinesterase inhibitors, including donepezil (Aricept), rivastigmine (Exelon), and galantamine (Razadyne), are...

Language and Cognition01:27

Language and Cognition

986
Language serves as a bridge between ideas and communication, influencing how individuals perceive and interact with the world. Psychologists have long debated whether language shapes thought or vice versa. This discussion gained grip with Edward Sapir and Benjamin Lee Whorf in the 1940s, who proposed that language determines thought, a concept known as linguistic determinism. They suggested that the vocabulary and structure of a language influence how its speakers think and perceive reality.

Modeling in Therapy01:26

Modeling in Therapy

736
Modeling, a key technique in therapy, uses observational learning to help clients acquire and practice new skills by watching therapists demonstrate desired behaviors. This approach, rooted in Albert Bandura's concept of vicarious learning, plays a significant role in therapeutic interventions for various psychological conditions, including social anxiety, ADHD, and depression.

Participant modeling involves therapists demonstrating calm and effective behaviors in...

Summary

Distributed aphasia therapy schedules improved language impairment more than intensive schedules. Both approaches enhanced functional communication and quality of life for individuals with chronic aphasia.

Area of Science:

  • Neurorehabilitation
  • Speech-Language Pathology
  • Clinical Neuroscience

Background:

  • Aphasia treatment intensity research lacks dosage control.
  • Understanding optimal therapy schedules is crucial for aphasia rehabilitation.

Purpose of the Study:

  • To investigate the efficacy of a dosage-controlled Aphasia Language Impairment and Functioning Therapy (ALIFT).
  • To compare intensive versus distributed therapy schedules for chronic aphasia communication outcomes.

Main Methods:

  • Thirty-four adults with chronic poststroke aphasia participated.
  • Treatment involved 48 hours of ALIFT, either intensive (16 hrs/wk for 3 wks) or distributed (6 hrs/wk for 8 wks).

Main Results:

  • Distributed therapy yielded significantly greater Boston Naming Test improvements (P=0.04) immediately and at 1-month follow-up (P=0.002).
  • Comparable gains in communicative effectiveness, confidence, and quality of life were observed for both schedules.

Conclusions:

  • Distributed ALIFT schedules are superior for improving language impairment in chronic aphasia.
  • ALIFT positively impacts functional communication and quality of life irrespective of intensity.
  • Findings inform clinical service delivery models for aphasia rehabilitation.
