Conceptual metaphor theory revolutionized our understanding of language and cognition. It proposes that we use concrete experiences to understand abstract ideas, shaping our thoughts and everyday language. This theory challenges traditional views of metaphor as merely a linguistic device.

Lakoff and Johnson's seminal work "Metaphors We Live By" introduced the idea of conceptual metaphors as cognitive mechanisms. They argued that metaphors are pervasive in thought and action, demonstrating how we understand abstract concepts through more concrete domains.

Origins of conceptual metaphor

• Conceptual metaphor theory revolutionized understanding of language and cognition in psychology
• Emerged as a key framework for exploring how humans conceptualize abstract ideas through concrete experiences
• Challenged traditional views of metaphor as merely a linguistic device

Lakoff and Johnson's contributions

• Published seminal work "Metaphors We Live By" in 1980
• Proposed metaphors shape thought processes and everyday language
• Introduced the idea of conceptual metaphors as cognitive mechanisms
• Argued metaphors are pervasive in both thought and action
• Demonstrated how abstract concepts are understood through more concrete domains

Cognitive linguistics foundations

• Developed within the broader field of cognitive linguistics
• Emphasizes the relationship between language, mind, and embodied experience
• Rejects the notion of language as an autonomous cognitive faculty
• Draws on insights from cognitive psychology and neuroscience
• Focuses on how linguistic structures reflect cognitive processes and conceptual organization

Structure of conceptual metaphors

• Conceptual metaphors consist of systematic mappings between conceptual domains
• Provide a framework for understanding abstract concepts in terms of more concrete experiences
• Allow for the transfer of inferential structures from familiar to unfamiliar domains

Source and target domains

• Source domain represents the concrete, easily understood concept
• Target domain is the abstract concept being explained or understood
• Mapping occurs from source to target, not bidirectionally
• Source domains often derive from bodily experiences or physical interactions
• Target domains typically involve abstract concepts, emotions, or complex ideas

Mapping between domains

• Involves systematic correspondences between elements of source and target
• Preserves the cognitive topology of the source domain
• Allows for inference and reasoning about the target domain
• Can be partial, highlighting certain aspects while hiding others
• Constrained by the Invariance Principle, which preserves the image-schema structure of the target

Types of conceptual metaphors

• Conceptual metaphors are categorized based on their cognitive functions and structures
• Different types of metaphors serve various purposes in conceptualization and reasoning
• Understanding these types helps analyze how metaphors shape thought and language

Structural metaphors

• Map one concept's structure onto another concept
• Provide rich knowledge about the target domain
• Allow for complex reasoning and inference
  • Time is money (Time can be spent, saved, wasted)
• Often used to understand abstract concepts through more concrete experiences
• Can shape cultural attitudes and behaviors towards the target domain

Orientational metaphors

• Organize entire systems of concepts with respect to spatial orientations
• Based on physical and cultural experiences
• Often involve up-down, in-out, front-back spatial relationships
  • Happy is up, sad is down (Feeling uplifted, feeling down)
• Tend to be consistent across cultures but can vary
• Influence how we conceptualize abstract qualities and emotions

Ontological metaphors

• Allow us to view events, activities, emotions, and ideas as entities or substances
• Provide ways to refer to, quantify, and identify aspects of abstract experiences
• Often involve personification or object metaphors
  • Inflation is an entity (Inflation is eating up our profits)
• Enable reasoning about abstract concepts as if they were physical objects
• Facilitate quantification and identification of abstract phenomena

Conceptual metaphor vs literal language

• Conceptual metaphors differ fundamentally from literal language in cognitive processing
• Understanding these differences is crucial for studying language comprehension and production
• Impacts how we interpret and analyze both everyday and specialized discourse

Differences in processing

• Metaphorical language activates both literal and figurative meanings initially
• Requires more cognitive resources to process than literal language
• Involves cross-domain mapping not present in literal comprehension
• May be processed faster in conventional metaphors due to familiarity
• Engages broader neural networks compared to literal language processing

Neural correlates

• Metaphor comprehension activates both hemispheres of the brain
• Right hemisphere shows greater involvement in novel metaphor processing
• Left hemisphere dominates in conventional metaphor understanding
• Prefrontal cortex plays a crucial role in metaphor interpretation
• Sensorimotor cortices activate when processing metaphors related to physical experiences

Cultural influences on metaphors

• Conceptual metaphors are shaped by cultural experiences and beliefs
• Studying cultural variations in metaphors provides insights into cognitive diversity
• Reveals how different cultures conceptualize and reason about abstract concepts

Universal vs culture-specific metaphors

• Some conceptual metaphors appear to be near-universal (Time as space)
• Culture-specific metaphors reflect unique historical or environmental factors
• Universal metaphors often stem from shared bodily experiences
• Culture-specific metaphors can reveal distinct worldviews or values
• Blend of universal and culture-specific metaphors in most languages

Cross-linguistic comparisons

• Reveal similarities and differences in conceptual metaphor use across languages
• Help identify potential cognitive universals in human thought
• Demonstrate how language shapes and is shaped by conceptual systems
• Provide evidence for linguistic relativity in metaphorical thinking
• Inform translation practices and cross-cultural communication strategies

Conceptual metaphor in cognition

• Conceptual metaphors play a crucial role in human cognitive processes
• Influence how we perceive, reason about, and interact with the world
• Provide a framework for understanding complex or abstract phenomena

Role in abstract thinking

• Enable comprehension of abstract concepts through concrete experiences
• Facilitate reasoning about intangible ideas or complex systems
• Shape problem-solving approaches in various domains
  • Understanding social relationships through spatial metaphors
• Influence decision-making processes by framing options metaphorically
• Contribute to creative thinking and innovation

Influence on reasoning

• Guide inferential processes based on source domain logic
• Affect judgment and decision-making in various contexts
• Can lead to systematic biases in reasoning (Moral cleanliness metaphor)
• Shape argumentation strategies in debates and persuasion
• Influence policy-making and public discourse on complex issues

Embodiment and conceptual metaphors

• Embodiment theory posits that cognition is grounded in bodily experiences
• Conceptual metaphors often derive from sensorimotor interactions with the environment
• Understanding embodiment is crucial for explaining the origins and structure of metaphors

Sensorimotor experiences

• Form the basis for many primary metaphors
• Provide concrete source domains for abstract target concepts
• Include experiences of temperature, movement, balance, and spatial orientation
• Influence how we conceptualize emotions, time, and abstract ideas
  • Anger as heat (Boiling with rage, cool down)
• Vary across cultures based on different physical environments and practices

Embodied cognition theory

• Proposes that cognitive processes are fundamentally shaped by the body
• Suggests that abstract thought is grounded in physical experiences
• Explains why many conceptual metaphors have a physical or spatial basis
• Predicts activation of sensorimotor areas during metaphor comprehension
• Challenges traditional views of cognition as purely symbolic processing

Criticism and limitations

• Understanding these limitations is crucial for refining and advancing the theory
• Critiques have led to ongoing debates and new research directions in cognitive linguistics
