What degree of control do we have on eye movements?

Short answer We have a lot of control over our eye movements, including saccades. We can suppress saccades and make an anti-saccade instead. So can monkeys, our close cousins. Children have a lot more ...

Is our attention attracted by bright lights?

In general, evidence suggests that we are attracted to contrast rather than brightness (luminance). For example, the onset of a bright light on a dark background is often used as an exogenous cue for ...

Why do people look in the face or eyes while communicating?

I don't have a complete answer, but I'll add on to Christian's comment. I'm not really familiar with an evolutionary account of facial expressions, but folks like Adam K. Anderson have implied that ...

How is saccadic movement managed in the brain?

I agree with much of AliceD's well-cited answer, but here are a few extras. What part of the brain is actively controlling saccadic movement? It is not clear how you would choose just one ...

How is saccadic movement managed in the brain?

The superior colliculus can be regarded as the center of saccadic eye movement. It contains a topographically organized representation of the visual space in its upper layers, and saccade-related ...

How important is eye contact for attraction between a man and woman?

While eye contact is certainly important in social interaction I think you should beware pseudoscientific dating advice based on manufacturing "attraction" between men and women. Since this site is ...

Why can’t my eyes gaze around at a constant rate?

Short answer Smooth-pursuit eye movements require something to pursuit. Intentionally attempting to make such an eye movement in the absence of an appropriate moving visual target will result in a ...

Is there visual focus during a saccade?

Short answer The retinal image cannot be refocused on an intermediate target during a saccade. Background Psychophysical experiments have shown that during a saccade, attention is aimed at the ...

What is the relationship between top-down mechanism and priming the visual system in the following experiment?

This is potentially an example of a top-down influence on the visual system. That is, if the experiment demonstrates as expected, that priming the visual system with a word influences the pattern of ...

Predicting the landing site of a saccade while the saccade is still in progress

This is an old question, but the following paper might be useful. The authors describe an algorithm of real-time prediction of saccadic landing point. The algorithm they use is based on a compressed ...

Predicting the landing site of a saccade while the saccade is still in progress

Interesting question! Trying to interpret your question, I think what you are after is a model that can predict the saccade endpoint based on eye tracking data? The following answer is more of a ...
