Medium for Communication: Language allows us to express thoughts, ideas, and emotions. It connects people across time and space. Importance of Language Facilitates Communication: Language allows individuals to share information, ask questions, and express emotions. It connects people across cultures and contexts. Example: Ordering food at a restaurant, making a phone call to a friend. Reflects Cultural Identity: Language is an integral part of culture, reflecting values, traditions, and identity. Example: Different dialects and accents within the same language can indicate regional origins or cultural backgrounds. Shapes Thought and Perception: The language we speak can influence how we think and perceive the world. Example: Some languages have words for specific emotions or phenomena that others do not, shaping how speakers of different languages view the world. Plays a Vital Role in Education and Society: Language is essential in education for teaching, learning, and sharing knowledge. Example: In classrooms, language is used to explain concepts, ask questions, and engage with subjects. Types of Language Verbal Language: Language expressed through speech or writing Examples: Spoken: Saying "Good morning!" to a friend. Written: Writing an email to your teacher or a text message to a colleague. Non-Verbal Language: Communication through body movements, facial expressions, and gestures Examples: Body Language: Crossing your arms can signal discomfort or defensiveness in a conversation. Facial Expression: A smile can convey happiness or friendliness. Gestures: Nodding your head to indicate agreement or using a hand wave to greet someone. Sign Language: A form of language that uses hand gestures, facial expressions, and body movements to convey meaning. Examples: American Sign Language (ASL): The sign for "hello" involves raising your hand in a "salute" motion. British Sign Language (BSL): "Thank you" is represented by touching the chin and moving the hand away. Formal and Informal Languages: Language registers adjust based on social context and the relationship between people. Examples: Formal: In a job interview, you would say, "Good afternoon, I am grateful for the opportunity to discuss my qualifications.“ Informal: When talking to a close friend, you might say, "Hey, what's up?  Nature of language Language is a complex communication system that involves using symbols, sounds, and grammar to convey meaning. It is unique to humans and allows for the expression of thoughts, emotions, and intentions. Key characteristics of language include: Arbitrariness Productivity Displacement Cultural Transmission  Key characteristics of language Arbitrariness refers to the lack of inherent connection between the words used in a language and their meanings. The relationship between a word and its meaning is arbitrary, there is no logical reason why a particular word represents a specific concept. Example: The word "tree" has no natural connection to the tall, woody plant it represents. Different languages use different arbitrary symbols for the same concept, like "arbre" in French or "baum" in German.  Productivity: Humans can create and understand an infinite number of sentences, including those they've never heard before. Example: Even if you've never heard the sentence "The green dragon flew over the rainbow," you can understand it perfectly well. This showcases language's productivity, as it allows you to produce and comprehend novel utterances.  Displacement: Language allows us to talk about things that are not present in space or time, such as past events or hypothetical situations. Example: When you talk about your vacation plans for next year, you are using displacement. You're discussing events that are not currently happening and that exist only in your future intentions and imagination. Cultural transmission refers to the way language and its usage are passed down from one generation to the next through social interaction, rather than through genetic inheritance. Example: A child born to Japanese parents but raised in France will grow up speaking French if French is the primary language of the community and household. This demonstrates cultural transmission, as the language learned depends on the cultural and social environment rather than genetic factors.  Language Acquisition Language acquisition is the process by which humans learn to perceive, produce, and understand language. It involves acquiring the ability to communicate using words, sentences, and grammar. This process begins in early childhood and continues as we grow, influenced by various cognitive, social, and environmental factors. Key theories and concepts: Innateness Hypothesis: Proposed by Noam Chomsky, this theory suggests that humans are born with an innate ability to acquire language. Chomsky introduced the concept of the Language Acquisition Device (LAD), an inherent brain mechanism that allows children to learn language naturally. Critical Period Hypothesis: This hypothesis posits that there is a critical period during early childhood when language acquisition occurs most easily. After this period, it becomes significantly more difficult to learn a language with native-like proficiency.  Learning Theories: Behaviorists like B.F. Skinner argued that language is acquired through imitation, reinforcement, and conditioning. Children learn language by mimicking the speech they hear and receiving positive reinforcement for correct usage. Social Interactionist Theory: Lev Vygotsky emphasized the role of social interaction in language development. According to this theory, language acquisition is driven by communication and social engagement with caregivers and peers. Cognitive Developmental Theory: Jean Piaget suggested that language acquisition is closely linked to cognitive development. As children grow and develop their cognitive abilities, their language skills also evolve.  Properties of Language 1. Duality of Patterning Definition: This property refers to the two levels of structure in language: individual sounds (phonemes) that are meaningless on their own and meaningful combinations of these sounds (morphemes and words). Example: Phonemes: The sounds /b/, /a/, and /t/ are meaningless by themselves. Words: When combined, they form the word "bat," which has a specific meaning (a flying mammal or a piece of sports equipment). 2. Discreteness Definition: Language is made up of distinct, separate units (sounds, words) that can be recombined in various ways to create different meanings. Example: The sounds /t/, /a/, and /b/ can be combined to form the word “tab" By rearranging these sounds, you can create the word “bat" which demonstrates the discrete nature of the sounds. 3. Syntax Definition: Syntax refers to the rules and principles for constructing sentences in a language, governing the order and combination of words. It determines how words are combined to form sentences and convey meaning. Example: English typically follows a Subject-Verb-Object order: "The cat (subject) chased (verb) the mouse object)." 4. Semanticity is the property of language that allows it to convey meaning. It refers to the use of symbols (words or signs) to represent objects, actions, ideas, and feelings in a way that others can understand. Example: Imagine you walk into a bakery and say, "I would like a chocolate cake, please." In this example, each word in your sentence carries specific meaning: "I" refers to the person speaking (you). "would like" expresses a desire or request. "a chocolate cake" refers to a specific type of baked good. "please" is a polite term used to make the request more courteous. The words in this sentence are symbols that represent real-world concepts (you, a desire, a specific item, and politeness). 5. Pragmatics Definition: Pragmatics involves how context influences the interpretation of language, including the speaker's intention and the social dynamics of the conversation. Example: If someone says, "Can you open the window?" during a hot meeting, they are likely making a request rather than questioning your ability to open the window.  Language comprehension Language comprehension is the process through which we understand spoken or written language. It involves decoding sounds or written words and interpreting their meaning based on the context. The process happens quickly in our brains, often without us even realizing the complexity involved. When we hear someone speak or read something, our brain processes and interprets that information by going through several mental steps to decode the message and make sense of it.  Six Steps of Language Comprehension 1. Perception: Receiving the Words What happens in this step? Perception is the very first step in language comprehension. It involves detecting and recognizing the spoken or written language. For spoken language: When we hear words, our brain translates sound waves into recognizable words. The sound is processed in our auditory cortex, which helps us identify the individual sounds or phonemes. For written language: When we read, our eyes send signals to the brain to recognize letters and words. This happens in the visual cortex of the brain, where the brain interprets the symbols (letters or characters) and recognizes them as meaningful words. Example: Spoken: If someone says "dog," your brain hears the sound and knows it means an animal with four legs. Written: If you read the word "dog," your brain recognizes the letters "d," "o," and "g" and processes them as the same concept. 2. Parsing: Breaking It Down What happens in this step? Parsing is the process of breaking a sentence into its grammatical components (like subject, verb, object) to understand its meaning. This step helps us figure out the roles of each word in the sentence. For example, when you hear or read the sentence, "The dog chased the ball," your brain breaks it down as: Subject: "The dog" Verb: "Chased" Object: "The ball" 3. Syntactic Processing: Understanding Sentence Structure What happens in this step? Syntactic processing is about understanding the grammar and structure of the sentence. The brain uses the rules of grammar to determine the relationships between words. For example, in English, word order is essential for understanding meaning. "The cat chased the mouse" has a different meaning than "The mouse chased the cat." 4. Semantic Processing: Understanding Meaning What happens in this step? In semantic processing, we decode the meaning of the words based on their definitions and context. This is when we understand what the words actually mean. For example, consider the word “bank”. It could mean: A place where you store money, or The side of a river. Example The word ‘bark’ could mean the sound a dog makes, or it could mean the outer layer of a tree. The context will tell you which one to choose. Why is semantic processing important? This step is crucial because it’s not just about recognizing words; it’s about understanding how each word fits into the broader meaning of the sentence. The context around the word helps determine which meaning we should apply. If you read “She went to the bank to get some cash,” you understand that the first meaning of "bank" (financial institution) is intended. If you read “He sat on the bank of the river,” the second meaning (side of the river) makes sense. 5. Integration: Connecting the Dots What happens in this step? Integration is the process of combining all the information you’ve processed—from perception to syntax to semantics—into a coherent, overall understanding. After your brain understands the meaning of the words, the structure of the sentence, and their relationship to each other, it integrates everything into one unified idea.  For example, when you hear or read the sentence "The dog chased the ball," after processing the words and their meanings, your brain integrates this information into a clear understanding that the dog is performing the action of chasing and the ball is the object being chased. 6. Response: Reacting to What We Understand What happens in this step? After your brain processes and integrates the information, the final step is responding to what you’ve understood. This could be: Speaking: You reply to a question or make a statement. Writing: You write a note, an email, or a message. Taking Action: You perform a task or follow directions.  Example: If someone asks you, "Can you help me with this?" after comprehending the question, you respond based on what you’ve understood. You might say, "Sure! How can I help?"  Why is Language Comprehension Important? Language comprehension is the foundation of communication. It’s used in every aspect of life: Reading: Understanding books, articles, emails, or instructions. Listening: Understanding conversations, lectures, announcements, etc. Speaking/Responding: Reacting appropriately when asked questions or when participating in conversations.  Case histories on language acquisition Case histories on language acquisition often focus on individuals or groups whose experiences provide unique insights into how humans learn language. Below are notable case histories that explore different aspects of language acquisition: 1. Critical Period Hypothesis Genie (1970s, USA): Background: Genie was a girl who suffered severe neglect and isolation, with almost no exposure to language until she was discovered at age 13. Findings: Despite extensive rehabilitation, Genie was unable to fully acquire grammatical structures, though she developed a vocabulary and basic communication skills. Her case supports the critical period hypothesis, suggesting a limited window during which humans can naturally acquire language.  Social interaction and early exposure are crucial for normal language development.  2. Bilingual and Multilingual Acquisition Werker's Research on Infant Bilingualism (1980s-1990s) Background: Studies by Janet Werker showed that infants exposed to multiple languages from birth can distinguish sounds from both languages, while monolingual infants lose sensitivity to non-native sounds by around 10 months. Findings: Bilingual children show cognitive flexibility and advanced problem-solving skills, though they may initially have smaller vocabularies in each language compared to monolingual peers.  Early exposure to multiple languages enhances linguistic and cognitive development. 3. Nicaraguan Sign Language (1980s) Background: Deaf children in Nicaragua, previously isolated, created a new sign language when brought together in a school for the deaf. Findings: Younger children were observed to refine and expand the system into a full-fledged language, showing the innate human ability to generate linguistic structures.  Social interaction plays a vital role in the natural development of language systems. 4. Wild or Feral Children Victor (1800s, France): Background: Victor, a boy found living in the wild, had no exposure to human language. Educator Jean Itard attempted to teach him. Findings: Victor learned some words but never developed full linguistic ability. His case also highlighted the importance of social interaction in language learning.  Language acquisition requires not only exposure to words but also meaningful interaction. THANK YOU FOR YOUR ATTENTION
