Summary
This study examined a bilingual woman with primary progressive aphasia. Both her native Friulian and second language Italian were affected, with greater impairments observed in Italian.
Area of Science:
- Neurolinguistics
- Psycholinguistics
- Clinical Linguistics
Background:
- Investigating language processing in bilingual individuals with neurodegenerative conditions.
- Understanding the impact of primary progressive aphasia (PPA) on multilingual language abilities.
- Utilizing the Bilingual Aphasia Test (BAT) for comprehensive linguistic assessment.
Observation:
- A case study of an elderly bilingual woman diagnosed with PPA.
- The participant's native language was Friulian (L1), and her second language was Italian (L2).
- Linguistic abilities were assessed across phonology, morphology, syntax, and lexical semantics using the BAT.
Findings:
- Both L1 (Friulian) and L2 (Italian) showed clinically significant effects of PPA.
- Distinctive impairment profiles were observed between the two languages.
- Greater phonological, morphological, grammatical, and syntactic deficits were noted in L2 (Italian).
Implications:
- Suggests potential dissociations within and between language systems in bilingual PPA.
- Highlights the utility of the BAT in characterizing language impairments in multilingual aphasia.
- Informs theoretical frameworks of bilingual language acquisition and processing under neurodegeneration.

01:27Language and Cognition
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.
01:28Lateralization
Brain lateralization refers to the division of mental processes and functions between the two hemispheres of the brain, a phenomenon that optimizes neural efficiency and underpins complex abilities in humans. This specialization allows each hemisphere to perform tasks where it has a comparative advantage, facilitating more refined cognitive capabilities across different domains.
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...

01:24Components of Language
Language, whether spoken, signed, or written, consists of specific components: lexicon and grammar. The lexicon is the vocabulary of a language, comprising its words. Grammar is the set of rules used to convey meaning through the lexicon. For example, English grammar adds “-ed” to most verbs to indicate past tense. Words are formed by combining phonemes, which are the basic sound units of a language. Different languages have different sets of phonemes (e.g., “ah” vs. “eh”). Phonemes combine to...
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...
