Men­tal self-rota­tion is the cog­ni­tive skill to imag­ine your­self in space and to imag­ine your­self mov­ing — such as when you read­ing a map or find­ing your car in the park­ing lot.

Imag­ine that you plan to go to a new Whole Foods store. You won­der whether going North on Big Bend Avenue you would have to make a right or a left turn onto Forsyth Blvd to get to Whole Foods. You then look at the map that your spouse has laid out on the table. It turns out that the map is upside down so your per­spec­tive is not aligned with the one shown on the map (see Fig­ure 1 below to the right, box A). How do you decide whether to turn left or right?

– Fig­ure 1

The map is upside down (A). The red dot rep­re­sents your car’s posi­tion. Your goal is to go to Whole Foods (W). You can either per­form an object rota­tion (B), that is imag­ine the map rotat­ing, or a self rota­tion ©, that is imag­ine your­self at the red dot loca­tion.

To align your per­spec­tive with the one shown on the map, you could imag­ine the map rotat­ing until it is upright. This is shown at the top right cor­ner of Fig­ure 1 above (Box B). This is what psy­chol­o­gists call men­tal rota­tion of object. Anoth­er solu­tion, which requires a high­er degree of con­cen­tra­tion, is to imag­ine view­ing the map from the oth­er side of the table. This is shown at the bot­tom right cor­ner of Fig­ure 1 above (Box C). Once you have imag­ined your­self on the oth­er side of the table you can use your body coor­di­nates and deter­mine that you will have to take a left on Forsyth. In that case, the map is not mov­ing but you are mov­ing. This is what psy­chol­o­gists call men­tal self-rota­tion.

Now the brain teas­er part: Ready to imag­ine your­self mov­ing in space?

For each map below count how many left and right turns you have to make to go from the Cir­cle to the Tri­an­gle. Fol­low the arrows. Do not move your body or your hands, try to do every­thing men­tal­ly.
