#BayesInPsych: Preventing miscarriages of justice and statistical inference

Your brilliant PhD student ran an experiment last week that investigated whether chanting the words “unicorns, Brexit, fairies” repeatedly every morning before dawn raises people’s estimates of the likelihood that they will win the next lottery in comparison to a control group that instead chants “reality, reality, reality”.

How the takete got its spikes: Why some words sound like what they are

Human beings have an incredible capability to communicate. Unlike other species, humans have evolved to use language to express our states, desires, observations, and, I guess, tweet about them.

When a flash a memory makes: Memorability of pictures in an RSVP task

What is it we remember, and why? Research in cognitive psychology has provided a broad and often very reliable sketch of the variables that determine memory performance.
