Last week Dr Sarah Rose, course leader for BSc Psychology and Child Development Award blogged about recreating some of the Piagetian Experiments with her children.

This week they have been having a go at some Theory of Mind tasks. These tasks are particularly suitable for children between the ages of about 3- and 7-years-old. We would love to hear how your children got on with these experiments, please tweet us @StaffsPsych or add your comments to this post!

Background

Psychologists are interested in how humans make sense of the world, this includes how they make sense of what others think. This ability to theorise and predict what someone else might be thinking develops with age and is called ‘Theory of Mind’.

This skill of predicting what another person may desire, believe, or feel usually develops between 3 and 7 years of age. The more psychologists have studied the development of theory of mind the more they have realised that it is not a single skill, instead it is a series of complex skills which develop over time.

False Belief Task 1: Sally and Ann

First we have had a go at recreating some of the classic Theory of Mind tasks testing ‘false beliefs’. These tasks require a child to understand that others may not have knowledge that they do, and which is correct. Therefore, they are called ‘false belief’ tasks as they require the child to recognise that someone else may have a ‘false belief’ about a situation.

One of the most famous of these false belief tasks is the story about two dolls, Sally and Anne:

Sally has a marble which she puts in a basket. She then goes on a walk. While she is on the walk Anne moves the marble to a box. Sally comes back from her walk and the child is asked where Sally will look for her marble.

To ‘pass’ this task the child needs to respond that Sally will look in the basket as she doesn’t know that the marble has been moved to the box.

Both my 4- and 6-year old seemed to enjoy this and found it relatively easy. If you would like to see the videos do have a look here. I used a paper prompt for the story about Sally and Anne, if you look on google you will find a few to choose from.

False Belief Task 2: Smarties Tube

Other versions of the false belief task have also been developed. Probably the most famous of these is the Smarties tube task. In this a child is shown a smarties tube (or some other familiar container, we used a pencil box).

The child is asked what they think is inside, as long as you have chosen something the child is familiar with, they should give you the expected answer, e.g. Smarties (or in my case pencils).

However, what the child doesn’t know is that prior to the experiment you have taken the expected contents out and replaced them with something unexpected! You then show the child the unexpected contents, this often gives them a good giggle. Then you close the container again and ask them what someone else, who hasn’t seen inside the container, would think was inside.

My 6-year old really enjoyed this task as he found it very funny. My 4-year old was a little more confused by it though (video can be found here). She thought that Nana would think there were sweeties in the pencil box! I did wonder if this might reflected the box that I had chosen as maybe she thought Nana would not be familiar with the box and therefore that it contained pencils Alternatively, maybe there is something about this task that she just found more difficult than the task about Sally and Anne?

Diverse Desire Task

Since the development of the false belief tasks it has become recognised that these tasks test just one aspect of Theory of Mind. If we are interested in children’s understanding of the minds of others, then we need more tasks as people’s minds are very complex. We need tasks that test children’s understanding of different types of thoughts, not just someone’s knowledge and beliefs.

One of these more recent tasks has been designed to test children’s understanding that the likes and desires of others may differ to their own. To test this, you will need a picture of two possible snacks (we used pictures of a cookie and a carrot) and a soft toy who can be the character in the story.
Now you are ready to engage in the following conversation with your child.

• Here are two different snacks, a carrot, and a cookie (show them the pictures). Which would you like best?
• Here is Farmer Tom (the name of the toy we used), and it is his snack time!
• Farmer Tom really likes (opposite to what child said). He does not like (what the child says), he likes (opposite to what the child said).
• So now it is snack time, Farmer Tom can choose what he would like to eat. Which snack will they choose, a cookie or a carrot?

To ‘pass’ this task the child needs to choose the snack for the toy character that the character likes – rather than the one that they would choose. Both of my children found this quite easy, you can see them having a go here. I was not surprised by this as understanding of diverse desires has been found to be one of the first Theory of Mind skills to develop, usually before the understanding of false belief

Real – Apparent Emotion Task

As well has having beliefs and desires we have emotions too. Some more recent Theory of Mind tasks, such as this story about Sam have aimed to investigate children’s understanding of the emotions that another person might feel and show – and that these may not always be the same as people can try and hide their emotions.

To test this understanding of emotion you will need a couple of paper props: a silhouette, or outline of a boy, and three face emojis (happy, neutral and sad). Make sure that your child is confident about the feelings that each of three faces represent and introduce the silhouette of the boy explaining that it is ‘Sam’ the boy in the story that you are about to read.

Now you are ready to read the story:

This story is about Sam. I am going to ask you some questions about how Sam is feeling, how he is really feeling on the inside, and how he looks on his face. He might feel one way inside but look a different way on his face. I want you to tell me how he really feels inside AND then how he looks on his face, okay?

• Sam’s friends were playing together and telling jokes.
• One of the older children, Rosie, told a mean, unkind joke about Sam and everyone laughed.
• Everyone thought it was very funny but Sam didn’t.
• But he didn’t want the other children to see how he felt about the joke, so Sam tried to hide how he felt.
• So, how do you think Sam felt on the inside when everyone else laughed at the joke?
• AND how did Sam try to look on his face?

To pass this test children need to recognise that although Sam felt sad inside, he tried to disguise his feelings by looking neutral or happy. I was surprised at how easy both of my children found this task as understanding of emotion has generally been found to be one of the later Theory of Mind skills to develop. This led me to wonder whether maybe taking the ‘test’ in a familiar environment with a familiar adult who they are used to listening to made it easier for them to pass the test?

Finally, some reflections on these tests…

Although the theory of mind tasks are tests of social cognition they also require good language skills as children really have to listen and understand what you are saying otherwise they would be likely to give the wrong answers. I think, like the Piagetian tasks I wrote about last week, that when we are able to present these tasks in a child friendly way that makes sense to the child we may find that some abilities develop slightly sooner than the theorist originally thought. These reminds us how important the environment and context is for children, if they feel comfortable and relaxed they may be better able to show us their true cognitive abilities.
