Study Notes on Comparative Cognition and Social Interaction

The goal is to discuss the cognitive science of social interaction from:
- Developmental perspectives
- Evolutionary perspectives
Emphasis on redefining cognition:
- Not limited to the brain or mind but encompasses groups of people or animals and their environments.
- Studying cognitive problems solved through interactions among these systems.

Began at Dartmouth College with a major in cognitive science and computer science.
Work history includes:
- Product manager in industry.
- Research at MIT focusing on autonomous vehicles and human interactions.
- Engagement with natural language processing during the emergence of large language models.
- Working on interspecies communication at a pet company.
- Studying comparative cognition of children, adults, and animals.
Noted that paths into cognitive science can vary widely due to its interdisciplinary nature.

Discussion opener about the distinction of human cognition through audience interaction:
- Proposals included:
- High-level language as a unique aspect.
- Imagination of things that don’t exist.
- Social intelligence highlighted:
- Two-year-olds outperform adult primates in social tasks despite similar performance in physical reasoning tasks.
Challenge posed:
- How is society possible within the context of uniquely complex human interactions compared to other species?
Quote from George Simmel: Society exists where a number of individuals enter into interaction.

Unique features analyzed in human interaction:
- Language: Important but not the sole medium of interaction.
- Interaction rituals including:
- How to start and end interactions without violating social norms.
Definition of Infrastructure for Social Interaction:
- An assemblage of norms, practices, artifacts, and attitudes to solve coordination problems.
- Examples of infrastructures to be discussed:
- Joint commitment during interactions.

Concept of Joint Commitment defined:
- Two individuals sharing a goal which creates expectations about their actions (e.g., sawing a log together).
Mutual signaling as an indicator of joint commitment:
- Study of children at preschools showed children start to treat interactions as joint commitments as young as age two.
Research findings indicate evidence of joint commitments in bonobos during grooming sessions, although limited to specific situations.

Study of cognitive abilities across evolution:
- Simultaneous examination of shared traits across species, inferring evolution of traits from common ancestors.
- Ontogeny recapitulates phylogeny: Development sequence in children mirrors evolutionary order (e.g., embryonic development).

Importance of Public Space defined as a key interaction arena.
The role of Proxemic Norms — social attitudes regarding spatial occupancy during interactions.
- Study conducted at Geisel Library demonstrating how pedestrians navigate public spaces based on perceived social interactions.
- Comparison of conditions influenced by mutual gaze versus looking at phones:
- Movement behavior was impacted by the perceived involvement of standing individuals.

Personal Space:
- Defined as an invisible boundary around the body that constrains close proximity by others.
Interactional Territory:
- Differentiated from personal space; it represents spatial claims of groups aimed at facilitating interactions.
- Assessed through behavior observations in research setups studying proximity norms and pedestrian behavior.

Research led by Max Potter examining Flexible Role Formation:
- Not merely for productivity but also to simplify communication in larger groups.
Study conducted using a cooking task (e.g., preparing omelets) measured role specialization and communication efficiency among participants.
- Increased role specialization with larger groups but not directly linked to productivity enhancement.

The mechanics of human conversation based on Adjacency Pairs:
- Fundamental organization of social actions (e.g., questions requiring answers) key to interactions.
Conversational Repair strategies:
- Repeating or reformulating questions when responses are unclear or absent, creating opportunities for responses.
Research findings on word acquisition in children:
- Emergence of interactional words (e.g. yes, no, bye) earlier than current theoretical predictions suggest, highlighting the role of interactions in language learning.

Bridging insights from human interactions to animal gestures:
- Comparison of gesture learning in primates (e.g., bonobos) and how communicative signals evolve through encoding functional actions into culturally learned gestures.
Mutual anticipation in developing signaling systems and similarities with early human word learning processes.

Emphasis on infrastructures for social interaction as facilitators of cumulative culture and social organization.
Cognitive Science as an interdisciplinary approach situated within multiple fields (linguistics, anthropology, computer science, psychology, philosophy, neuroscience).
Closing acknowledgment of contributions from the Comparative Cognition Lab and suggested readings for further study on related topics in cognitive science.
