Language and Language Use
How Do We Use Language?
Common Ground:
Shared knowledge between a speaker and a listener.
Example: Assumptions that people understand the meaning of words.
Facilitates coordination in language use.
Audience Design:
Speakers tailor their communication based on the audience's knowledge.
Example: A specialized audience may not require basic explanations.
Levels of Language Use:
Lexicon: Collection of words and expressions.
Syntax: Grammatical rules for arranging words and expressions.
Speech Rate: The speed at which one speaks.
Accent: Variations in pronunciation depending on locale.
Similar levels of language use arise in conversation; individuals mimic expressions from one another.
What Do We Talk About?
Gossip (60-70% of conversations):
Discussion about oneself and others.
Viewed as a socialization act and regulation tool in social contexts.
Promotes friendship.
Ingroup vs. Outgroup:
Ingroup: Groups to which a person belongs.
Outgroup: Groups to which a person does not belong.
Social Brain Hypothesis:
Human brain evolution supports maintaining larger ingroups through advanced thoughts.
Linguistic Intergroup Bias:
Tendency to represent ingroups favorably and outgroups negatively.
Positive aspects described using adjectives indicative of permanency (E.g., "He is generous").
Negative aspects described using verbs indicative of particularity (E.g., "He gave a man some change").
Psychological Consequences of Language Use
Sapir-Whorf Hypothesis:
Language influences thought processes.
Individualism vs. Collectivism:
English language's frequent use of explicit personal pronouns (e.g., "you," "I") associates with an individualistic culture.
Theory of Mind
The Role of Theory of Mind in Social Life
Theory of Mind:
Human ability to understand others' mental states.
Important for social interactions and community engagement.
Essential in acts such as:
Teaching or learning.
Language acquisition through monitoring others.
Understanding how others perceive us.
Sharing experiences.
Collaborating.
The Mental Processes Underlying Theory of Mind
Agents, Goals, and Intentionality:
Agents: Identifying entities that can act (e.g., moving objects).
Goals: Understanding agents pursue specific ends.
Intentionality: Distinguishing intentional actions from mere goals; intentional behaviors are more sophisticated.
Imitation, Synchrony, and Empathy:
Imitation: Observation and replication of others' behaviors. Mimicry is a subtle form of imitation.
Mirror Neurons: Neurons that activate both during action execution and observation of the same action in others.
Synchrony: Shared behaviors reflecting common internal states.
Automatic Empathy: Unconscious adoption of another's emotional state through mimicry.
Joint Attention and Visual Perspective Taking:
Joint Attention: Awareness of shared focus on an object.
Visual Perspective Taking: Inferring another’s thoughts or feelings by seeing from their viewpoint.
Projection and Simulation:
Social Projection: Assuming others share one’s desires or knowledge.
Simulation: Representing another’s mental state internally.
Explicit Mental State Inference:
Requires differentiation between personal knowledge and that of others.
False-Belief Test: Evaluates the recognition of beliefs that contradict reality.
