Human visual experience usually provides ample opportunity to accumulate knowledge about events unfolding in the environment. In typical scene perception experiments, however, participants view images that are unrelated to each other and, therefore, they cannot accumulate knowledge relevant to the upcoming visual input. Consequently, the influence...

The visual input that the eyes receive usually contains temporally continuous information about unfolding events. Therefore, humans can accumulate knowledge about their current environment. Typical studies on scene perception, however, involve presenting multiple unrelated images and thereby render this accumulation unnecessary. Our study, instead,...

Humans constantly move their eyes to explore the environment. However, how image-computable features and object representations contribute to eye-movement control is an ongoing debate. Recent developments in object perception indicate a complex relationship between features and object representations, where image-independent object knowledge genera...

Semantic information is important in eye movement control. An important semantic influence on gaze guidance relates to object-scene relationships: objects that are semantically inconsistent with the scene attract more fixations than consistent objects. One interpretation of this effect is that fixations are driven toward inconsistent objects becaus...

Humans constantly move their eyes to explore the environment and obtain information. Competing theories of gaze guidance consider the factors driving eye movements within a dichotomy between low-level visual features and high-level object representations. However, recent developments in object perception indicate a complex and intricate relationshi...

The concerns raised by Henderson, Hayes, Peacock, and Rehrig (2021) are based on misconceptions of our work. We show that Meaning Maps (MMs) do not predict gaze guidance better than a state-of-the-art saliency model that is based on semantically-neutral, high-level features. We argue that there is therefore no evidence to date that MMs index anythi...

Eye movements are vital for human vision, and it is therefore important to understand how observers decide where to look. Meaning maps (MMs), a technique to capture the distribution of semantic information across an image, have recently been proposed to support the hypothesis that meaning rather than image features guides human gaze. MMs have the p...

Using computer programming is a necessity for many PhD students in psychology: you may be required to write computer code to run an experiment, prepare easily reproducible data analysis and visualisation procedure, or build computational models. If mastering programming skills is imperative for your academic progress, this article presents practica...

Native speakers of languages share implicit knowledge about wordlikeness of previously unknown words, allowing them to judge whether those belong to their language or not [Bailey and Hahn, 2001]. This phenomenon can be partially explained by statistical patterns, e.g., bi-gram transitional probabilities [Frisch et al, 2000]. Our study investigates...

Radical Plasticity Thesis proposed by Cleeremans (2011), claims that learning process plays a significant role in shaping conscious experience. In order to investigate this assumption we designed two experiments using binocular rivalry paradigm (BR). This paradigm enables experimental triggering of changes in the participants’ subjective experience...
