Summary
Speech apraxia error patterns in Brazilian Portuguese differ from international findings. This suggests language influences speech sound errors in apraxia, impacting therapy development.
Area of Science:
- Linguistics
- Speech-Language Pathology
- Neurology
Background:
- Phonological characterization of speech apraxia errors aids understanding and therapy development.
- Most speech apraxia research is not in Brazilian Portuguese (BP), limiting national literature.
- Existing BP literature relies on international studies.
Purpose of the Study:
- To conduct a phonological analysis of speech errors in Brazilian Portuguese speakers with speech apraxia.
- To identify specific phoneme errors common in BP speakers with apraxia.
Main Methods:
- Evaluated 20 adults diagnosed with speech apraxia.
- Analyzed phonological errors, including substitutions and omissions.
Main Results:
- Identified specific phonemes (/b/, /lambda /, /3 /) as highly affected in BP speakers with apraxia.
- These frequently affected phonemes differ from those reported in international studies.
Conclusions:
- Speech apraxia error patterns appear to be language-dependent.
- Findings suggest that language influences the specific phonological errors observed in individuals with apraxia.

01:10Higher Mental Functions of the Brain: Language
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...

01:22Language Development
Children master language quickly and with relative ease, supported by both biological predisposition and reinforcement. B. F. Skinner (1957) proposed that language is learned through reinforcement, while Noam Chomsky (1965) argued that language acquisition mechanisms are biologically determined.
The critical period for language acquisition suggests that the ability to acquire language is at its peak early in life. As people age, this proficiency decreases. Language development begins very...

01:24Prosopagnosia
Prosopagnosia, also known as face blindness, is the inability to recognize faces. In severe cases, individuals with prosopagnosia may not recognize close family members, including parents and spouses, by their faces. For instance, someone with prosopagnosia might walk past their child in a crowd, only realizing their mistake upon noticing their child's distinctive backpack or favorite jacket. Prosopagnosia specifically impairs facial recognition, while the recognition of other objects or...
