There are some tasks that require cognitive processes that are habitual, automatic, and to some degree effortless, such as seeing a word and automatically reading it or seeing two numbers and automatically processing their magnitudes (e.g., seeing 5 and 3 and perceiving 5 to be greater). There are other tasks that require cognitive processes that […]

Roadie folklore has it that there are some towns in rural Texas or Saskatchewan that are so small, you miss them if you blink too long while cruising down some highway to nowhere. This is unlikely to be actually true, although figuratively speaking, I can think of a few rural towns in Western Australia that […]
Have you ever had a conversation with someone who constantly averted their gaze? Why do you think that is? If you are like most people, you might suspect a myriad of reasons, with most being categorically not good. You might suspect that your conversational partner is socially uncomfortable, disinterested in the conversation, hiding something, or […]
Apparently the internet, video games, and social media are damaging our children’s development, and are responsible for the increase in autism over the last few decades—or so it has been claimed, although that claim hasn’t withstood scrutiny. Similarly, Wikipedia has an entry for something known as Internet addiction disorder, which apparently occurs when internet use […]
Imagine settling into the well-deserved holiday on the Ningaloo Reef. The Indian Ocean is warm and gentle and you go for your first exploratory snorkel. The corals are beginning to recover from their latest bleach and the number and coloring of the tropical fish is as enchanting as it is astounding. And then you take […]
You reach for the life-saving glass of water handed to you from the judge’s bench, with a bit of assistance from your co-defendant. You take a sip and the rest is movie history. What happens to your attention during that sequence of events? When we plan a movement, for example to reach for a glass […]
We have talked about pop-out before. The phenomenon is nearly self-explanatory: consider the two sets of dots in the figure below. There are 18 dots on the left and 150 on the right. In each array, there is a single red dot: what is your intuition about how long it would take to detect the […]
What goes up, but never comes down? If you guessed age, then you are absolutely right. Despite the significant advancements made in science, we have yet to reverse time or stop the process of aging (sorry anti-aging creams). As a result, many people suffer from a fear of getting old (known as Gerascophobia). But are […]
William James famously said that the world is “one great blooming, buzzing confusion” to an infant whose sensory apparatus is “assailed by eyes, ears, nose, skin, and entrails at once.” As adults, we continue to be assailed by stimuli, but out attentional apparatus permits us to deal with the blooming and buzzing confusion quite well.

How long is a piece of string? We all know this proverbial and largely rhetorical question. We also probably assume that it has no right answer—indeed, that’s the point of this rhetorical question in the first place, namely to indicate that the issue under consideration does not have a meaningful answer. Enter the venerable BBC. […]
