To investigate the effect of context on memory, I would use an independent groups design. I would recruit 20 participants and randomly allocate them to one of two conditions.
**Procedure and Data Collection:**
All participants would be taken to a specific room (e.g., a science lab) and given 5 minutes to learn a list of 20 words.
- **Condition 1 (Same Context):** The 10 participants in this group would be asked to recall the words in the same science lab where they learned them.
- **Condition 2 (Different Context):** The other 10 participants would be taken to a different room (e.g., a library) and asked to recall the words there.
The data I would collect is the number of words correctly recalled by each participant out of 20. This is quantitative data.
**Extraneous Variable and Control:**
An extraneous variable could be the time of day the experiment is conducted, as participants might be more alert in the morning. To control this, I would ensure all participants are tested at the same time of day, for example, between 2 pm and 4 pm.
**Expected Results:**
Based on the principle of context-dependent memory, I would expect the participants in Condition 1 (Same Context) to recall significantly more words correctly than the participants in Condition 2 (Different Context). This is because the environmental cues present during learning would also be present during recall for Condition 1, acting as triggers for memory.
This question requires you to design a simple experiment based on the principle of context-dependent memory. This principle states that we are more likely to recall information if we are in the same environment (context) where we first learned it. A good experimental design will have two conditions to compare: a 'same context' group and a 'different context' group. The independent variable is the context of recall, and the dependent variable is the accuracy of memory, which must be measured quantitatively (e.g., a score). Controlling extraneous variables is crucial for ensuring that any difference between the groups is due to the IV and not other factors. The expected result is that the 'same context' group will have better recall, supporting the theory.
