Individuals rapidly create new communication systems when needed, but skills vary. This study found that both individual cognitive traits and how similar partners are in those traits influence success in building novel communication from scratch.
Area of Science:
- Cognitive Science
- Psychology
- Communication Studies
Background:
- Humans possess an innate ability to create novel communication systems when existing ones fail.
- Significant inter-individual differences exist in the capacity for communicative innovation.
- Understanding the psychological underpinnings of this variability is crucial for comprehending collaborative communication.
Purpose of the Study:
- To identify psychological sources of inter-individual variability in establishing novel communication systems.
- To investigate whether individual cognitive traits or dyadic trait overlap better predicts communicative success.
- To analyze how cognitive traits influence strategy selection in novel communication tasks.
Main Methods:
- Assessed cognitive traits using psychometric measures for cooperative attitudes and fluid intelligence.
- Quantified communicative innovation competence via a non-verbal task with communicating dyads.
- Analyzed the relationship between individual cognitive traits, dyadic similarities, and communicative performance.
Main Results:
- Individual cognitive capacities significantly influenced communicative success in generating innovations.
- Dyadic similarities and individual traits modulated the choice of communicative strategies.
- Novel communicative action development depended on the communicator's intention recognition and the addressee's pattern recognition.
Conclusions:
- Successful novel communication arises from a combination of individual abilities and dyadic interactions.
- Comparable systemizing abilities or behavioral inhibition in pairs facilitated exploration of communication strategies.
- Communicative innovation is a complex collaborative activity, not solely dependent on single psychometric measures.
