Key Takeaways
1. Human Cognition's Foundation: Social and Cultural Transmission
There is only one possible solution to this puzzle. That is, there is only one known biological mechanism that could bring about these kinds of changes in behavior and cognition in so short a time—whether that time be thought of as 6 million, 2 million, or one-quarter of a million years. This biological mechanism is social or cultural transmission, which works on time scales many orders of magnitude faster than those of organic evolution.
Time is of the essence. The rapid evolution of human cognition, far outpacing biological evolution, points to social and cultural transmission as the driving force. This mechanism allows individuals to leverage existing knowledge and skills, saving time and effort.
Cultural transmission is widespread. While cultural transmission exists in various forms across species, from birds mimicking songs to chimpanzees learning tool use, the human capacity for it is unparalleled. This is due to the unique ability to understand conspecifics as intentional beings.
Human beings are unique. This understanding enables complex forms of cultural learning, including imitative, instructed, and collaborative learning. These processes are the foundation for the accumulation of knowledge and the development of complex societies.
2. Uniquely Human Cognition: Understanding Intentionality
The most plausible hypothesis is thus that nonhuman primates understand conspecifics as animate beings capable of spontaneous self-movement—indeed, this is the basis for their social understanding in general and their understanding of third-party social relationships in particular—but do not understand others as intentional agents in the process of pursuing goals or mental agents in the process of thinking about the world.
Beyond Animacy. The key difference between human and non-human primate cognition lies in the understanding of intentionality. While primates recognize animate beings, humans perceive others as goal-oriented agents with intentions and mental states.
Intentionality enables flexibility. This understanding allows humans to predict and influence behavior in creative and flexible ways. It also transforms social learning, enabling powerful forms of cultural transmission.
Social understanding first. The ability to understand intentionality likely evolved first in the social realm, allowing humans to predict and explain the behavior of conspecifics. This understanding was then applied to the physical world, leading to a deeper comprehension of causality.
3. Cultural Inheritance: The Engine of Cognitive Advancement
Most importantly, the cultural traditions and artifacts of human beings accumulate modifications over time in a way that those of other animal species do not—so-called cumulative cultural evolution.
The Ratchet Effect. Human culture is characterized by cumulative cultural evolution, where traditions and artifacts are modified and improved over time. This "ratchet effect" requires both innovation and faithful social transmission.
Faithful transmission is key. Many animal species exhibit intelligent innovations, but lack the social learning mechanisms to preserve and build upon these advancements. Human cultural learning, driven by the understanding of intentionality, ensures faithful transmission.
Pooling cognitive resources. This ability to pool cognitive resources allows humans to create complex tools, technologies, and social institutions that no single individual could have invented alone. It is the foundation of human progress.
4. Ontogeny: The Interplay of Biology and Culture
But there is nothing odd about the product of a given process contributing to, or even becoming an essential factor in, the further development of that process.
Dual Inheritance. Human development depends on both biological and cultural inheritance. While biological inheritance provides the foundation, cultural inheritance shapes and transforms cognitive abilities.
The "Like Me" Stance. A key biological difference is the human tendency to "identify" with conspecifics, understanding them as beings like themselves. This identification drives cultural learning and internalization.
Historical and Ontogenetic Processes. The species-unique cognitive skills of humans are not solely due to biological inheritance. They result from historical and ontogenetic processes set in motion by the uniquely human capacity for understanding others as intentional agents.
5. Joint Attention: The Gateway to Cultural Learning
These newly emerging joint attentional activities represent nothing other than the ontogenetic emergence of the uniquely human social-cognitive adaptation for identifying with other persons and so understanding them as intentional agents like the self.
The Nine-Month Revolution. Around nine months of age, infants begin to engage in joint attentional behaviors, indicating a new understanding of others as intentional agents. This marks a turning point in social-cognitive development.
Triadic Interactions. Joint attention involves coordinating interactions with objects and people, creating a referential triangle. This includes gaze following, joint engagement, social referencing, and imitative learning.
Understanding Intentionality. Joint attentional behaviors are not isolated skills, but reflections of infants' dawning understanding of others as intentional agents. This understanding is crucial for cultural learning and participation in the world of culture.
6. Language Acquisition: A Social-Cognitive Symphony
Thought is not merely expressed in words; it comes into existence through them.
Language as a Social Act. Language acquisition is not simply about learning labels for objects. It is a social act in which individuals attempt to direct the attention of others.
Joint Attentional Scenes. Language learning occurs within joint attentional scenes, where shared understanding and intentionality provide the context for symbolic communication. These scenes are the foundation for acquiring linguistic symbols.
Communicative Intentions. To learn language, children must understand the communicative intentions of others, recognizing that linguistic symbols are used to direct their attention. This understanding is crucial for acquiring the conventional use of language.
7. Linguistic Constructions: Shaping Event Cognition
Every particular notation stresses some particular point of view.
Beyond Words. Language acquisition involves more than just learning words. Children also acquire linguistic constructions, which are larger symbolic units that shape how they understand events.
Verb Island Constructions. Initially, children's linguistic competence is comprised of verb island constructions, where specific verbs are associated with specific syntactic patterns. These constructions are concrete and item-specific.
Abstract Constructions. Over time, children abstract across verb island constructions to create more general and productive linguistic constructions. This process transforms their cognitive representations and allows for greater flexibility in language use.
8. Discourse: Weaving Perspectives into Understanding
Any utterance is a link in a very complexly organized chain of utterances.
Language in Context. Understanding language requires more than just knowing words and grammar. It also involves understanding how language is used in discourse, the back-and-forth of conversation.
Discourse and Perspective-Taking. Discourse interactions, including disagreements, clarification sequences, and didactic exchanges, expose children to different perspectives and challenge them to reconcile conflicting viewpoints.
Dialogical Representations. These interactions lead to the development of dialogical cognitive representations, where children internalize multiple perspectives and engage in self-reflection. This process is crucial for developing complex cognitive skills.
9. The Power of Symbols: Transforming Cognitive Representation
We may say that thinking is essentially the activity of operating with signs.
Beyond Sensory-Motor. Language acquisition transforms cognitive representation, moving beyond sensory-motor experiences to symbolic and perspectival understanding. Linguistic symbols embody cultural knowledge and shape how individuals construe the world.
Intersubjectivity and Perspective. Linguistic symbols are intersubjective, shared with others, and perspectival, reflecting a particular way of viewing the world. This combination creates a unique form of cognitive representation.
Cultural Cognition. By internalizing linguistic symbols, children gain access to the accumulated knowledge and perspectives of their culture. This process enables them to engage in complex forms of reasoning, problem-solving, and creative thinking.
