Today, we tried to reason

How’d you do on this test?

 

Reasoning Test                                                                                  100% = A                   < 100% = F

This test consists of four reasoning tasks. You should do them in order, reading the instructions carefully, not proceeding to the next task until you have completed the one before it.

 

Task 1: Even Vowels

E T 4 7
       

Imagine that you are employed in quality control by a card manufacturer. They are producing a series of cards for an experimental psychologist, according to the following rule: if a card has a vowel on one side, then it has an even number on the other side.

There are four of these cards at left. You know for certain that each card has a letter on one side and a number on the other. In light of this knowledge, check the box(es) under the card or cards you definitely need to turn over, and only that or those cards, in order to determine whether the rule is broken in the case of any of these four cards.

Task 2: Colored Circles and Squares

Imagine that you have been employed by a board games manufacturer to ensure that the cards in one of their games have been correctly produced.  The rule governing the production of the cards states that if a card has a circle on one side, then it has the color yellow on the other.

There are four such cards at right. You know for certain that each card has a shape on one side and a color on the other. In light of this knowledge, tick the box(es) under the card or cards you definitely need to turn over, and only that or those cards, in order to determine whether the rule is broken in the case of any of these four cards.

 

Task 3: Sly Beer Drinking

You are the owner of a bar and you are very concerned that underage-drinking laws should be correctly enforced. Your bar is situated in a university town, and you suspect that some of your clientele might be students not yet old enough to drink legally. At present, the law states that if a person drinks an alcoholic drink (e.g., beer), then they must be more than 21 years old.

The cards below have information about the ages and drinking habits of four of the customers at your bar. Each card represents one person. One side of a card details the age of the person. The other side of the card indicates what they have been drinking.

In light of this knowledge, check the box(es) under the card or cards you definitely need to turn over, and only that or those cards, in order to determine whether the rule is broken in the case of any of these four drinkers.

 

Task 4: Surfing at Work

Imagine that you are the owner of a small company employing some twenty people. You have noticed that your employees seem to be spending a lot of time during work hours surfing the Web for personal pleasure. You consider this practice to be a perk rather than a right, so you have introduced a rule that states that if an employee spends more than two hours a day during work time on the Web, then they must have made at least $5K for the company in the last month.

   Spent 1 hour on  the Web Spent 3 hours

  Made $3K

  Made $7K
last month
       

The cards below have information about the Web-surfing habits of four of your employees. Each card represents one employee. One side of the card details how much time the employee has spent on the Web during the last working day. The other side details how much money they have made for the company in the last month.

In light of this knowledge, tick the box(es) under the card or cards that you definitely need to turn over, and only that or those cards, in order to determine whether the rule is broken in the case of any of these four employees.       – Taken from Do You Think What You Think You Think?
