Kiki or Bouba? Sound Symbolism in Vision-and-Language Models
Morris Alper,
Hadar Averbuch-Elor
NeurIPS (spotlight), 2023
Presentation from IMVC 2024
By generating images using prompts containing pseudowords (nonsense words) and analyzing their
shapes,
we show that AI image generation models show sound-shape associations similar to those known from
human psychology.

Learning Human-Human Interactions in Images from Weak Textual Supervision
Morris Alper,
Hadar Averbuch-Elor
ICCV, 2023
We propose to model human-human interaction understanding in images as free text
generation, providing a new benchmark and showing how to use Internet image captions
as weak supervision for this task.

Is BERT Blind? Exploring the Effect of Vision-and-Language Pretraining on Visual Language
Understanding
Morris Alper*,
Michael Fiman*,
Hadar Averbuch-Elor
*Equal contribution
CVPR, 2023
We investigate the effect of vision-and-language pretraining on visual reasoning in text, finding
that multimodally trained text encoders outperform unimodally
trained encoders such as BERT on such tasks.

Featured in the News:
- Our work on the Kiki-Bouba effect and sound symbolism in AI models was featured
in the Haaretz newspaper (Hebrew language). I was also interviewed about this work on the Kan Tarbut morning radio program
(recording link, 46:30-60:00, Hebrew language).

Awards and Honors:
-
As a high school student, I qualified to join the USA team at the International
Linguistics Olympiad (IOL) for three years (2008, 2009, 2011). In particular, in 2011 I won
1st place (gold medal)
on individual and team rounds in 2011 as well as receiving the Zhurinski Memorial Prize and a best
solution award. I also received a silver medal (tied for 6th place) in 2008 and our team won the
team round in 2009.
