Towards affective computing that works for everyone
Missing diversity, equity, and inclusion elements in affective computing
datasets directly affect the accuracy and fairness of emotion recognition
algorithms across different groups. A literature review reveals how affective
computing systems may work differently for different groups due to, for
instance, mental health conditions impacting facial expressions and speech or
age-related changes in facial appearance and health. Our work analyzes existing
affective computing datasets and highlights a disconcerting lack of diversity
in current affective computing datasets regarding race, sex/gender, age, and
(mental) health representation. By emphasizing the need for more inclusive
sampling strategies and standardized documentation of demographic factors in
datasets, this paper provides recommendations and calls for greater attention
to inclusivity and consideration of societal consequences in affective
computing research to promote ethical and accurate outcomes in this emerging
field.Comment: 8 pages, 2023 11th International Conference on Affective Computing

Communication Drives the Emergence of Language Universals in Neural Agents:Evidence from the Word-order/Case-marking Trade-off
Artificial learners often behave differently from human learners in the context of neural agent-based simulations of language emergence and change. A common explanation is the lack of appropriate cognitive biases in these learners. However, it has also been proposed that more naturalistic settings of language learning and use could lead to more humanlike results. We investigate this latter account, focusing on the word-order/case-marking trade-off, a widely attested language universal that has proven particularly hard to simulate. We propose a new Neural-agent Language Learning and Communication framework (NeLLCom) where pairs of speaking and listening agents first learn a miniature language via supervised learning, and then optimize it for communication via reinforcement learning. Following closely the setup of earlier human experiments, we succeed in replicating the trade-off with the new framework without hard-coding specific biases in the agents. We see this as an essential step towards the investigation of language universals with neural learners.</p

Cognitive biases and social coordination in the emergence of temporal language
Humans spatialize time. This occurs within individual mindsand also in larger, shared cultural systems like language.Understanding the origins of space-time mappings requiresanalyses at multiple levels, from initial individual biases tocultural evolution. Here we present a laboratory experimentthat simulates the cultural emergence of space-timemappings. Dyads had to communicate about temporalconcepts using only a novel, spatial signaling device. Overthe course of their interactions, participants rapidlyestablished semiotic systems that mapped systematicallybetween time and space. These semiotic systems exhibited anumber of similarities, but also striking idiosyncrasies. Byforegrounding the interaction of mechanisms that operate ondisparate timescales, laboratory experiments can shed light onthe commonalities and variety found in space-time mappingsin languages around the world
Double-blind reviewing and gender biases at EvoLang conferences
A previous study of reviewing at the Evolution of Language conferences found effects that suggested that gender bias against female authors was alleviated under double-blind review at EvoLang 11. We update this analysis in two specific ways. First, we add data from the most recent EvoLang 12 conference, providing a comprehensive picture of the conference over five iterations. Like EvoLang 11, EvoLang 12 used double-blind review, but EvoLang 12 showed no significant difference in review scores between genders. We discuss potential explanations for why there was a strong effect in EvoLang 11, which is largely absent in EvoLang 12. These include testing whether readability differs between genders, though we find no evidence to support this. Although gender differences seem to have declined for EvoLang 12, we suggest that double-blind review provides a more equitable evaluation process
Emergence of systematic iconicity: transmission, interaction and analogy
Abstract Languages combine arbitrary and iconic signals. How do iconic signals emerge and when do they persist? We present an experimental study of the role of iconicity in the emergence of structure in an artificial language. Using an iterated communication game in which we control the signalling medium as well as the meaning space, we study the evolution of communicative signals in transmission chains. This sheds light on how affordances of the communication medium shape and constrain the mappability and transmissibility of form-meaning pairs. We find that iconic signals can form the building blocks for wider compositional patterns
