Just seeing reminders of coffee can stimulate us
Simply looking at something that reminds us of coffee can cause our minds to become more alert and attentive, scientists say. The study looks at an effect called priming, through which exposure to even subtle cues can influence our thoughts and behaviour. “Coffee is one of the most popular beverages and a lot is known about its physical effects,” said Sam Maglio, an associate professor at University of Toronto in Canada. “Much less is known about its psychological meaning – in other words, how even seeing reminders of it can influence how we think,” said Maglio.

In this case the researchers wanted to explore how simply being exposed to things that remind us of coffee may have an effect on arousal. Across four separate studies and using a mix of participants from western and eastern cultures, they compared coffee- and tea-related cues. They found that participants exposed to coffee-related cues perceived time as shorter and thought in more concrete, precise terms. “People who experience physiological arousal see the world in more specific, detailed terms,” said Maglio.
