What you describe is an illusion. (a) The human field of view is almost 180° when staring straight ahead and 270° with eyeball rotation (looking to the side without turning your head). If you look at someone from slightly behind and to the side, they will appear to be gazing forward, and you may feel unnoticed, but in fact you are within their field of ...

Rather than discuss limits of the human field of view, or extrasensory perception (I don't know anything about the first, and the second is a myth), I think we can look at this as a simple case of illusory correlation (wikipedia), which is both a psychological phenomenon, and something psychologists need to overcome to investigate other phenomena. In a ...

This very much depends on what, exactly, you're trying to do. EEG measurements tend to be extremely reliable, but the inferences one may draw on mental state are not necessarily so. EEG-driven BCI overwhelmingly relies on machine learning to correctly classify signals into a finite number of categories and act upon them. Typically, you'll do something ...

I've studied this a little bit within the context of timing responses to personality test items. General models of reading speed look at both the time to read the words as well as to comprehend. From memory, eye tracking studies have shown how the eyes will often back track to confusing parts of a sentence (apologies for lack of reference). Some general ...

Research shows that teenagers are not any less capable at driving, per se, but that the adolescent brain undergoes a period of neural changes that often lends itself to risk-seeking behavior. From Somerville et. al (2010): In adolescence, there is a heightened propensity to engage in risky behaviors that can lead to negative outcomes, including substance ...

It's an interesting phenomena. And I think it can be seen in many other domains beyond lifts. At least where I live, pedestrian crossings have buttons, which I've seen people repeatedly press. You can see it often on computers and other digital devices when the system does not immediately respond to user input. Basic Bayesian Rational Actor My starting ...

The images you've linked are composites, and so probably don't contain the characteristics by which raters were able to judge IQ accurately. The original article (Kleisner, Chvátalová, & Flegr, 2014) is freely available and appears to answer your question in its abstract: Faces that are perceived as highly intelligent are rather prolonged with a ...

If you really wanted to know you could use models of reading behaviour - e.g. EZ-Reader or Swift. The Rayner reviews are the classic go-to to outlne this kind of thing: Rayner, K. (2009). Eye movements and attention in reading, scene perception, and visual search. The Quarterly Journal of Experimental Psychology (2006) (Vol. 62, pp. 1457-506). It will ...

ISO 9241, a standard covering ergonomics of human-computer interaction, defines in its subsection 9241-110, "Dialogue Principles", that the interface in information systems should be (among other things): suitable for the task facilitate learning conform with user expectations describe its own purpose and functioning You could translate all this to: ...

Benefits of touch typing on task performance: I assume that when comparing skilled individuals, two handed touch typing on a traditional keyboard is faster, more reliable, and more automatic, than the other methods of text input that you mention (e.g., phone or tablet keyboards). These advantages are discussed here. Faster input means that ideas can be ...

Presumably the decision of drivers to slow down in response to work zone signage is influenced by many factors. Signage and road factors: Presumably there are a wide range of factors related to the nature of the signs and the structure of the road setting that influence whether people slow down. For example, I've seen road work signage on freeways that ...

The answer is no. Definition of imprinting is: A rapid learning process by which a newborn or very young animal establishes a behavior pattern of recognition and attraction towards other animals of its own kind, as well as to specific individuals of its species, such as its parents, or to a substitute for these. Ducklings, for example, will imprint upon and ...

A few thoughts spring to mind: Part of the answer might depend on the maximum value of X (if all the messages are relatively short, that's a key piece of information). It doesn't decay, I don't think. The more information presented to the user, the more it all has to put into context with each other. But I don't think it's quadratic, either; that seems ...

Multiple causes of not reading instructions As @crash notes, there are likely many explanations for not reading instructions. It may be motivated by not caring about task performance. And such dispositions may be specific to the particular task or setting, or they might be partially related to some general disposition of the individual in terms of ...

Presumably, most updates to system interfaces are designed to achieve some goal related to the owner of the system. Often this would be usability, but of course, it could be something else like profitability, security, etc. Interface changes for non-usability related goal: So the first point is that a subset of interface updates are performed with a goal ...

The answer is "yes." The entire field of Human Factors and Ergonomics is devoted to enhancing the experience of the human user. Cognitive engineering is the branch of human factors that focuses specifically on how people perceive and respond to system interfaces. Engineers and scientists in this field try to design components, systems, interfaces, and even ...

If what you are seeking is how to present material so that cognitive overload does not occur, you are in the realm of learning theory.[1] Cognitive load theory and schema (learning) theory go hand in hand in. Schemas are frameworks of information (like a steel-framed skyscraper in your mind); they start as very basic ("This is a cell") and become more ...

Beyond what you've already listed, you'll need advanced signal processing skills, as so far, nobody has figured out how to get much more meaningful information out of the EEG than broad attentional state (alpha blocking and the P300, and the evoked potentials), and maybe some correlates of motor imagery, though none of these have realistically proved ...

As the author of the blog post you refer to, I can state that at the time of writing (early 2011) there were not too many studies reporting on this specific topic, which is why I reported on the single study I found at the time (Binkley et al. 2009). However, I advise you to read a follow-up study by a different group of researchers (Sharif and Maletic ...

Well, actually I have often had the experience that buttons on appliances signal that they have been pressed but nevertheless the appliance does not react. For example, right here under my computer is an external hard disk. A light glows when I press the on/off button. Still, the hard disk does not turn on about 80% of the time, when I press the button (the ...

I just had a project where I had to figure this out. I found that a good rule of thumb was the following: $$timeToRead = 1300 + (chars * 65);$$ So that's an initial time of 1300ms to adjust to what you need to be reading and about 65ms per character including spaces.

Since you mentioned the Stroop specifically, several versions of the Stroop task are available for Inquisit here. Randall Engle's lab also maintains a set of validated working memory tasks, which are available on request to researchers. They include full and shortened versions of operation-, symmetry-, reading- and rotation-span for E-Prime 2.0. Assuming I ...

Yes. The phenomenon is usually referred to as Visual Dominance or Visual Capture. A very nice demonstration of it, is known as McGurk Effect, in which our vision of the speaker's lips biases our perception of the sound we hear [1]. The McGurk Effect can be seen in a demo video here. Another demonstration of a similar effect is ventriloquism, in which we ...

Often, very similar phenomena have different names when studied in different modalities, because they are studied by different communities. That's why searching for perception response times + auditory doesn't yield great results (Although I did find [1] this way). Something else to try, is to pick a highly cited paper that you did find, and then search ...

On the EEG side, you'll need a way to access the EEG data in real-time so that you can perform whatever computational techniques you need to do in order to generate signals to control the TV. Some of the newer commercial-oriented EEG headsets have SDKs that you may be able to use. We've used the Emotiv system in our lab for mobile EEG research, and they have ...

There is a lot of context to extract from this: For example if "using the X tool" requires a lot of time, it would be time-consuming to actually go by yourself and try for hours, when you could instead ask for help from someone who already has some knowledge of it. Also, people are all different, some people want to know how "things work in their ...

Question: Are there any techniques to improve reading from screen? Yes! I employ many different "techniques" myself: Temporary on-the-fly changes to websites which I do not frequent. Cut-N-Paste content to a text editor. Temporary changes for my viewing needs. Permanent changes for my viewing needs to sites I frequent. You bring an important point ...
