WELCOME TO THE SCENE GRAMMAR LAB!
The temporal dynamics of semantic integration of objects
Delving into the depths of object recognition, our latest paper – co-authored by Melissa and Dejan – taps further into how contextual cues influence semantic object processing. Our findings, using computational modeling and representational similarity analysis, illuminate the temporal dynamics of semantic integration in congruent versus incongruent scenes. The study, published in Language, Cognition & Neuroscience, reveals distinct EEG patterns differentiating object processing of congruent and incongruent objects from 300ms onwards. Notably, we've identified a prolonged semantic integration phase for incongruent objects post 275ms, shedding light on contextual information's pivotal role in accessing semantic object details. Read the full paper for a deeper understanding of this fascinating exploration!

Aging & Memory - A new Paper!
Lena Klever, Jasmin Islam, Melissa Lê-Hoa Võ, and Jutta Billino just published their latest paper called “Aging attenuates the memory advantage for unexpected objects in real-world scenes”. They compared younger and older adults’ memory while freely viewing photographs of scenes similar to the picture on the right. For instance, toothpaste (green box) is expected close to the bathrooms' sink, but a bottle of ketchup (red box) is a rather incongruent object to be found in most showers. Does aging influence how well these objects can be recognized? Find out all about their work here.

We are happy to share with you Julia's latest paper titled "Flipping the world upside down: Using eye tracking in virtual reality to study visual search in inverted scenes".
In this study, Julia, Jason, Erwan, Dejan and Melissa investigated how scene inversion in virtual reality, in combination with eye tracking, affects visual perception and search behavior. You can download the paper here!
July 7th 2023
Three times congrats, Jacopo!!
The SGL is super proud to share two new papers with you:
Jacopo and Melissa investigated if the hierarchical organization of objects in scenes is reflected in the mental representations of objects. You can read up about it here. Also they got their paper on object and word frequency effects in categorization behavior accepted to JEP:GEN which you will can check out in our Publications tab once it's out! Beyond that, we want to throw out a BIG CONGRATS to Jacopo for handing in his thesis! We're looking forward to toasting to you in person.

Today we're proudly sharing some exciting news with you: Jason just got his second paper - called "Auxiliary scene context information provided by anchor objects guides attention and locomotion in natural search behavior" - accepted in Psychological Science. Together with Dejan and Melissa, he investigated how eye and body movements are guided by anchor objects in immersive virtual reality scenes. Have a look here!
February 18th 2022
SGL strikes again!
We're happy to announce that we just published another awesome paper at the Journal of Vision. Erwan, Julia and Melissa wanted to find out how the perceived roles of central and peripheral vision translate to more natural settings, so they conducted a gaze-contingent experiment in virtual reality to investigate this! If you, too, want to know more about this topic, you can download their paper here. Grab it while it's hot!

Review paper on Scene Grammar out now
In this comprehensive review paper, Melissa discusses how the meaning and structure of real-world scenes influence attention allocation, search, and object identification.
It provides a great overview of relevant research on scene perception and brings everything we've learnt so far into context. You can read all about it here.
Congratulations, Melissa, for this amazing work!
January 10th 2021
Get Your Guidance Going!
We are proud to announce that Julia just got her first SGL paper published as first author. Congratulations! Along with Jason, Dejan and Melissa, she investigated the activation of spatial priors for efficient search in virtual reality. They were able to eliminate the search initiation effect by previewing a scene before having participants search through it. Their results suggest that the effect is due to a process of orientation that slows down search at first. You can read
more about it here.

The scene-inconsistency effect in toddlers
If you found a bottle of milk in the bathroom, you would probably be quite surprised. This is because you hold strong expectations about what objects belong in which scene. But at what age do you
form these semantic predictions about your environment that lead to you being surprised by the milk in the bathroom?
Laura, Sabine and Melissa investigated this by presenting 24-month-olds with scene-consistent as well as scene-inconsistent objects in an ERP experiment. Their results provide first indications that by the age of two toddlers have already established their scene semantics allowing them to detect a semantic object-scene inconsistency.
Check out their amazing (and hard!) work here.

Congratulations to Erwan...
...for publishing his first paper in the SGL! Together with Julia and Melissa, he investigated the effects of central versus peripheral vision during real-world search in a 3D environment. They implemented a gaze-contingent protocol and masked central or peripheral vision, while participants were looking for objects in simulated everyday rooms. You can find out all about it here. Kudos!

We already know that semantically consistent objects tend to be better recognized than inconsistent ones.
But surely you have been asking yourself what role scene and object orientation plays in this. Look no further! We have the answer. Tim, Verena, Laura and Melissa investigated this influence by presenting upright and inverted objects in upright, inverted and scrambled scenes. Their paper just got published in Behavioural Brain Research. You can read all about it here.
July 29th 2020
We are happy to share some exciting news with you: Sabine's PhD work on how children process and use scene grammar got published in the Journal of Experimental Child
Psychology! She tested 72 children ranging from 2 to 4 in two types of tasks that measured scene knowledge: Either directly by asking them to furnish a dollhouse or indirectly by
analyzing their eye movements during scene viewing. If you want to know more, you can read the paper here. Congratulations, Sabine!
March 26th 2020

Last but not least we wish to thank all students for their active participation and the valuable feedback we received.
July 3rd 2019
Melissa, Sage & Dejan had a look at how scene grammar guides attention and aids perception in real-world environments and argue that so-called "anchor objects" are essential for scene perception. Anchors tend to be prominent objects that are representative for a scene. Not only do they aid scene categorization, but they also play a key role in object search and object identification. If you want to find out more about how scene grammar rules the world, download the article here!

January 7th 2019
Sage, Dejan, Melissa and Eric just published a paper in the Journal of Vision. They investigated the role of anchor objects on eye movements in visual search in a series of three eye tracking experiments. Participants were asked to look for a cued object in a scene and it was shown that relevant anchor objects - in comparison to irrelevant, but semantically consistent anchors - led to faster reaction times, less scene coverage and less time between fixating the anchor and the target.
