Q: What low-level visual features guide infants’ attention in naturalistic scenes? Intensity? Color? Orientation?

A: Orientation!
shannonmklotz.bsky.social
So grateful to have collaborated with @briannakhunter.bsky.social, @johnkiat.bsky.social, Christian Nelson, Steve Luck, and @lisaoakes.bsky.social on this one.

More to come on how infants learn to navigate the complexity of the visual world!

3) Importantly, the influence of orientation was modulated by visual clutter—it had stronger predictive power in less cluttered scenes.

These findings suggest that while infants’ attention is still influenced by low-level salience, not all features are equal—and their use evolves with development.

1) Infants’ fixations were strongly predicted by orientation, and this effect grew with age.

2) Color and intensity did not reliably predict gaze overall, though color was slightly predicting the fixation locations of the youngest infants.

We examined how 4-12-month-olds allocate attention while viewing scenes, using the Graph-Based Visual Salience (GBVS) model to break salience into its component features: orientation, color, and intensity. Across two experiments with over 160 infants, we found that:

What a great conference filled with great speakers and presenters!

Erim and I were so happy to share our work examining the efficacy of multiple choice quizzes that allow for multiple attempts on student final course grades.

I've got an exciting #Visionscience and #STEMed announcement: My textbook "Practical Vision: Learning through Experimentation" is now in production at Routledge Books! The book focuses on hands-on, analog exercises to identify and discuss key mechanisms of human vision. Coming October 2024!

Yuko Munakata’s plenary talk at #CDS2024 was **chef’s kiss**

She highlighted the role of social contexts (norms, cultural habits, systems, etc.) can play in how kids engage in executive function.

Older infants looked more at meaningful regions, aligning with prior research predicting a shift from relying on stimulus-driven factors to higher-level cognitive processes. This transition contributes to a more adult-like gaze behavior over the first year of life.
A graph that displays the probability of fixation as a function of the meaning, both measured as standardized z-scores. The graph plots fixation probability on the y-axis, which ranges from 0 to 1, against meaning on the x-axis, which ranges from -3 to 3. There are three lines, each representing different z-scores of infant age: +2 (dark red), 0 (medium red), and -2 (light red). The lines are accompanied by shaded areas of the same color that indicate the confidence intervals, showing the range of variability around the estimates. The lines suggest that the fixation probability increases with the meaning, and this relationship is moderated by the age of the infant, with different slopes indicating how the age affects the attention to meaningful content.

We found that infants preferentially fixated regions high in local meaning, physical salience, and closer the the center of the screen. 

Interestingly, meaning had a greater impact on infants' fixations than saliency, similar to findings in adults during natural scene viewing.
A graph depicting the relationship between fixation probability on the y-axis and standardized predictors on the x-axis, which are labeled as Z scores ranging from -3 to +3. Four lines of different colors represent different predictors: Meaning, GBVS (Graph-Based Visual Saliency), Center Proximity, and Infant Age.

Each line has a shaded area around it, indicating the confidence interval or variability in the data. The 'Meaning' predictor is depicted in red and has a positive slope, suggesting that as the meaning increases, the probability of fixation also increases. The 'GBVS' predictor is in blue, also with a positive slope but is flatter. 'Center Proximity' in green shows the steepest positive slope, indicating that as the distance from the center increases, the likelihood of fixation decreases. 'Infant Age' in purple has a slightly negative slope.

We wanted to know whether infants look to regions high in meaning but, just as importantly, whether they avoid regions with low meaning. To investigate, we compared infants' fixated locations to simulated non-fixated locations in terms of meaning, saliency, and center proximity.
Composite of four panels labeled a, b, c, and d.

Panel a shows a image of a kitchen with green and blue dots overlaid. Green dots indicate fixations and blue dots indicate non-fixated locations. A blue circle and a green circle highlight a specific blue dot and green dot, respectively.

Panel b-d are heatmaps labeled 'Meaning', 'Image Saliency', and 'Center Proximity'. The heatmaps vary from dark to light, with brighter areas indicating higher levels of that feature. The same blue and green circles from panel a are overlaid.

We examined the influence of local meaning on the gaze patterns of infants aged 4-12 months towards naturalistic scenes, using meaning maps developed by John Henderson and Taylor Hayes. Our analysis controlled for physical salience and center bias.

Q: Adults attend to locally meaningful regions in naturalistic scenes. Do infants? 

A: Yes! 🧵
