You eat like a pig.

Pigs acquire, through learning and evolution, expectations of their environment. Frustration of expectations results in motivation to change these conditions and is therefore adaptive. Initially, frustration should produce problem solving behaviour. If these responses are unsuccessful, other behaviours, reflecting general frustration should be elicited. Our purpose was to study both types of responses to frustration in grower pigs.

So these scientists took 18 pigs, and fasted them for 1, 2 or 3 hours every morning. On Monday and Tuesday the pigs got full feeders BUT on Wednesday and Friday they got 2 types of feeders – lidded with the lid bolted down (L) and un-lidded that was empty (O). Results showed that pigs in pairs showed an increase in sitting and playing and single pigs started to ignore the L-feeders after 2 hours while increasingly looked into the O-feeders.

Influencing Flow


Today I tried a little excercise on the lunch queue at Konstfack. I was interested in seeing how queues would form around obstacles, and how people would behave towards instructions.

I placed 3 signs (the ones normally used inside bulidings to alert people to dangers such as slippery floors) in the path the queue usually forms. Two had instructions on them in the form of a direction and one was blank. #3 Sign was placed directly in front of the tray pick-up point directing people in the opposite way, #2 near the menu board where most people stop for a moment to decide what they will order and #1 futher away where the queue normally forms to. I was particularily interested in how people would deal with #3, as it directly obstructed where people picked up their tray.
