Read the following information.

A researcher investigated whether participants found it easier to perceive distance if the objects used in the study were familiar to them.

The researcher placed objects at various distances away from the participants. The researcher then asked the participants to estimate how far away from them each object was in metres.

Some objects were familiar to the participants and other objects were unfamiliar to the participants.

Each participant saw an identical set of objects.

The researcher counted up how many times the participants correctly estimated the distance within one metre.

Table 2 shows the results from the study.

Read the following information

Watch out – dinosaurs about!

Watch out – dinosaurs about! A mobile phone company produced an app called DinoCatch to encourage people to exercise and enjoy more time outdoors. Someone playing DinoCatch would ‘catch’ digital dinosaurs on their mobile phone. These dinosaurs appeared on their screen when the player arrived at outdoor locations such as parks.

A researcher wanted to assess the impact of DinoCatch in the town of Waterlake. She counted the number of visitors to Waterlake Park between 1–2 pm during each of the 7 days before DinoCatch was introduced and at the same time during each of the 7 days afterwards.

Write a suitable alternative hypothesis for this study.

A psychologist carried out a study to see if there was any variation in the recall of events between people who speak different languages.

The psychologist used an opportunity sample to gather participants who were either English speakers or non-English speakers. The participants were shown video clips of people breaking a window. Sometimes they broke it on purpose and sometimes it was an accident.

When the participants were asked to write down what they had seen, the non-English speakers were less accurate in their recall of the clips that showed accidental behaviour.

Identify the independent variable in the described study.

Read the item and then answer the questions that follow.

A psychologist conducted a memory experiment, showing people sets of numbers and then taking the numbers away and asking them to write down what they had seen.

In Condition A, participants saw nine numbers written in groups of three for 10 seconds, for example, 746 826 392. They were then given 10 seconds to write down the numbers they had seen. This was repeated 10 times with different sets of numbers.

In Condition B, the same participants saw nine numbers written in one group of nine for 10 seconds; for example, 746826392. The participants were given ten seconds to write down the numbers they had seen. This was repeated 10 times with different sets of numbers.

The psychologist recorded the total number of recall errors made by each participant.

Professor Sharma is conducting an experiment to test whether eating chocolate before a psychology test affects the results students achieve.

Half of the 40 students were randomly allocated to Condition A: eating 50 g of milk chocolate 30 minutes before the test. The other half were allocated to Condition B: eating no chocolate before the test.

The test score (out of 100) was recorded for all students.

Write a suitable null hypothesis for this study.

Read the following information.

A researcher carried out a study with two groups of participants.

In Group A, 10 participants were given one list of 25 everyday objects to learn. Then they were asked to write down the objects they could recall. The researcher recorded how many objects were correctly recalled.

In Group B, 10 participants were given one list of 25 everyday objects to learn. Then they were given a second list of 25 everyday objects to learn. None of the objects on the second list were also on the first list. After this, the researcher asked the participants to write down the objects they could recall from the first list only. The researcher recorded how many objects were correctly recalled from the first list.

Identify the independent variable and the dependent variable in this study.

Read the following information.

A researcher carried out a study into false memory. Each participant was shown five photos and asked what they remembered about these events from their childhood.

However, only four of these photos showed a genuine event from their childhood. The other photo showed a fake image of the participant on a hot air balloon ride. None of the participants had ever experienced a hot air balloon ride.

Calculate what fraction of the photos shown to each participant were fake.
