  1. EXPERIMENT 3Psychology PracticalA41YP3

  2. INSTRUCTIONS • Today we are going to run our third experiment in the class. For this purpose I’m going to give you a problem solving task in which a series of thirty 4-digit numbers will be showed (one by one) to you on the screen. • Your task is to sum the first two digits, then sum the second two. If the sum of the first two is higher than that of the second two, then write “A” on the sheet (previously distributed). If the sum of the second two is higher, write “B”. If the sum is equal write “AB”.

  3. INSTRUCTIONS • You will have 15 seconds for each 4-digit number in order to write down your answer (A, B or AB) on the “problem solving task” sheet. • Ok, if there are no questions or doubts on the “problem solving task” we are going to start. Remember though that each 15 seconds a new slide presenting a new 4-digit number will appear on the screen.

  4. INSTRUCTIONS • The problem solving task is finished and I’d like you to turn over your “problem solving task” sheet. • For the second part of the experiment I’m going to show you another 10 slides one by one. Each of these will show a pair of 4-digit numbers, one named “A” and the other “B”. A B EXAMPLE: SLIDE 2754 3962

  5. INSTRUCTIONS • One member of each pair (A-B) presented in the slides was already shown to you during the problem solving task, which is why now you are asked to write down which member of the showing pair (A or B) you saw previously (memory task). • So, as the first pair of 4-digit numbers are presented, write down (1), and beside this write which of “A” or “B” you saw in the problem solving phase. For the second pair write (2) and which of “A” or “B” you saw previously, and so on for the ten pairs.

  6. INSTRUCTIONS • For each pair you will have 5 seconds in order to write down your answer before another pair of numbers will be shown to you, so your answer should be as quick as possible. • Ok if there are no questions or doubts on the memory task we are going to start. Remember though that each 5 seconds a new slide presenting a new pair of 4-digit numbers will appear on the screen.

  7. EXPLANATION • First of all, did anyone notice anything about the numbers in the experiment? • If not, then you should know that the first task you were asked to do in reality wasn’t a “problem solving task” but an “incidental learning task” in which all the 4-digit numbers contained a “3” (a “positive”).

  8. EXPLANATION • The second task (surprise memory test) was to investigate whether you would choose the digit string containing a “3” as the one you had seen previously. • In reality though, none of the 4-digit numbers in the memory test had been seen by you in the incidental learning phase. But, if you implicitly learned some rule during the incidental learning task (“that digits contain a 3”), then you may have used this rule (without being aware of it) to decide which of the pairs you had already seen (that is, you chose the digit string containing “3” as the one already seen).

  9. DATA COLLECTION • Now to test our hypothesis, that the member of the pair which contained a “3” was chosen as the one already seen, we are going to collect the data as always in an excel table. • To collect the data I’m going to ask you, for each one of the 10 slides of the test phase, if your answer was “A” or “B”. So, I will ask “How many of you answered “A” for the first slide?” You should check your answer on the sheet and raise your hand accordingly.
