Learning Unit 1: Language and the Brain
● Overview: This unit addresses the intricate relationship between language and the brain, exploring various
disciplines that investigate this connection.
● Disciplines Studying Language and Brain:
● Linguistics: Studies the structure and function of language, including phonology, morphology, syntax,
semantics, and pragmatics. It focuses on intuitive knowledge of language.
● Psycholinguistics: Focuses on mental processes involved in language, like speech production and
comprehension. Developmental psycholinguistics studies language acquisition in children.
● Neurolinguistics: Examines how brain mechanisms enable language use and the effects of brain damage on
language abilities. Key questions include the location of language in the brain and the representation of language
components.
● Learning Outcomes: After completing this unit, students should understand the relationship between language
and the brain, as well as the methods used to investigate these functions.
Note 3
Learning Unit 1 Content Breakdown
● Contents: The unit includes sections on the brain's structure, language areas, investigation methods, and
studies of aphasia.
● Key Questions Addressed:
● What is the relationship between brain and language?
● How is language located in the brain?
● How are language functions investigated?
, ● Aphasia Studies: Focus on Broca’s and Wernicke’s aphasia to illustrate the impact of brain damage on
language abilities. The unit will summarize the findings from these studies and the implications for understanding
language acquisition.
Note 4
Interdisciplinary Nature of Psycholinguistics and Neurolinguistics
● Both psycholinguistics and neurolinguistics are interdisciplinary studies involving multiple disciplines.
● Psycholinguistics combines psychology and linguistics.
● Neurolinguistics combines neurology and linguistics.
● Other disciplines like speech therapy and cognitive science also contribute to the understanding of language
and the brain.
● The focus of each discipline may vary, but they all investigate the relationship between language and cognitive
processes.
Note 5
Definitions and Matching Exercise
● The following disciplines and their definitions were matched:
1. Developmental psychology - D. studies how humans grow and change across their lifespans.
2. Neurolinguistics - F. examines the relationship between language and the brain.
3. Psycholinguistics - E. investigates what mental processes are involved in cognition.
4. Developmental psycholinguistics - B. studies children’s language as it develops through various stages.
5. Linguistics - A. is the scientific study of human language.
6. Cognitive science - C. is the study of mental processes.
● This matching exercise emphasizes the overlap and distinctions between disciplines studying language.
Note 6
Structure of the Brain
● The brain consists of neurons, which are specialized cells that transmit information.
● Grey matter is the outer layer of the brain (the cortex) and contains about ten billion neurons.
● The brain has three main parts:
● Brain stem: controls vital functions (respiration, heartbeat).
● Cerebellum: regulates balance and coordination of movements.
● Cerebrum: contains two cerebral hemispheres connected by the corpus callosum.
● Each hemisphere contains four lobes:
● Temporal lobe
● Frontal lobe
● Occipital lobe
● Parietal lobe
● The motor cortex located in the frontal lobe controls muscle movements, including speech.
Note 7
,Lateralisation and Localization of Language
● Localization refers to the attempt to identify specific areas of the brain responsible for certain cognitive
functions, including language.
● Lateralisation indicates that one hemisphere may become dominant for specific functions, such as language
processing.
● Broca's area is associated with speech production deficits if damaged, while Wernicke's area relates to
speech comprehension deficits.
● Generally, the left hemisphere is dominant for language in most individuals, with about 70% of left-handers also
having language functions in the left hemisphere.
Note 8
Investigating Language and the Brain
● Various methods are employed to investigate brain functions related to language:
● Sodium amytal tests: used to determine the dominant hemisphere for language.
● Dichotic listening tests: reveal a right ear advantage, indicating left hemisphere dominance.
● Brain-imaging techniques (e.g., PET scans, fMRI) provide dynamic images of brain activity during language
tasks.
● Event-Related Potentials (ERPs): measure brain response times to linguistic stimuli, shedding light on
processing mechanisms.
● These methods have advanced our understanding of the brain's role in language processing and the bilateral
contributions of both hemispheres.

Shona Language Examples
7. Nyama yaipisisa kuti idyike. (The meat was too hot to eat) (no negative deflection)
8. Nyama yaipisisa kuti inwike. (The meat was too hot to drink) (weak negative deflection)
9. Nyama yaipisisa kuti iravike. (The meat was too hot to read) (strong negative deflection)
Note 10
Aphasia Studies Overview
● Definition: Aphasia is a language impairment resulting from brain lesions due to strokes, tumors, infections, or
head injuries.
● Prevalence: Affects approximately 1 in 250 people (Mirman et al., 2015).
● Common Cause: Most often caused by a stroke, where blood clots disrupt blood flow, leading to brain swelling
and dysfunction.
● Recovery: Although serious symptoms occur initially, many patients experience improvement as surrounding
brain areas recover.
● Research Importance: Studying aphasia enhances understanding of language processing areas in the brain,
primarily Broca’s area and Wernicke’s area.
Note 11
Writing a Paragraph in Linguistics
● Expectations: Students must write coherent paragraphs (10-20 lines) to describe processes, present
arguments, or discuss theories.
, ● Key Steps:
● Read the question carefully: Identify the topic and instructional keywords (discuss, describe, explain).
● Plan the paragraph: List main ideas and determine their order.
● Writing Guidelines:
● Start with a topic sentence that introduces the discussion.
● Use continuous text instead of bullet points.
● Include definitions of key terms and ensure logical flow with linking words.
● Avoid irrelevant information and do not copy directly from learning materials.
● Use original examples for better marks.
● Review: Reread to ensure adherence to guidelines and that the question is answered directly.
Note 12
Evaluating Paragraph Structure
● Task 1.4 Analysis:
● The example paragraph lacks an introductory sentence, diving directly into content.
● There is repetition regarding the sodium amytal test.
● Includes irrelevant details about carotid arteries.
● Omits important information about brain-imaging techniques.
● Contains three separate paragraphs instead of one cohesive paragraph.
● Misspelling of the term 'dichotic' and grammatical errors noted.
● Fails to connect aphasia study back to the question about investigating the brain.
Note 13
Broca's Aphasia Characteristics
● Observations:
10. Broca's area develops late, reaching full maturity by age four.
11. It is less developed in higher primates.
● Speech Characteristics:
● Speech is slow and laborious; often lacks intonation and stress, resulting in a monotonous tone.
● Frequent omissions of function words (articles, prepositions, pronouns).
● Known as agrammatism, where speech resembles a telegram, missing grammatical elements but retaining
basic sentence structure.
● Examples of Speech:
● Patients may produce simplified utterances, struggle with reading aloud, and show errors in the use of
grammatical elements.
● Compensatory Strategies:
● Use of simple sentences joined with 'and'.
● Direct quotations instead of embedded sentences.
