If you wake up expecting a stressful day, you will make more mistakes
A recent study by Hyun et al indicated that if you wake up in the morning expecting to experience stress, your working memory function will be impaired throughout the day.

We assume physically attractive people are clever too.
We manage to get through the complications of modern life by using heuristics. These are mental rules of thumb which may or may not be accurate, but which save us time and effort.

It is well known that we make first impressions remarkably quickly, but few people realise that it is almost instantaneous.

Feelings of guilt are important drivers of prosocial behaviour. If we feel guilty about something, we are more likely to do a favour for someone else. Ego depletion is a state in which our combined resource for emotional, physical and mental effort has been drained by exertion in one of those areas, and has not…

A hard session at the gym decreases your ability to resist temptation.
Physical, emotional and mental effort all seem to draw from the same attentional resource. This pool of attention is limited and a period of effort in any of these forms runs down this resource.

Inattention Blindness: You don’t even see a lot of what you are looking at.
If you are reading this online, first follow this link and watch the video, then come back. You would think that if you are looking in a particular direction then you see whatever is there, as long as it is light enough. Unfortunately not. Inattention blindness is the term given to the fact that we…
