Question

Roberto is telling Rachel about some juicy gossip when she stops him and informs him that she is the one who passed this gossip on to him about a week ago. In this example, Roberto has: A. been fooled by the misinformation effect. B. made a reality-monitoring error. C. made a source-monitoring error. D. made a prospective memory error.

Short answer

Answer: Roberto made a source-monitoring error.

Step-by-step solution

Misinformation effect: This occurs when a person's memory of an event is influenced by misleading or false information. It typically happens when they come across new information after the original event took place. Reality-monitoring error: This is a type of memory error where a person confuses whether a memory is of a real event or an imagined one. Source-monitoring error: This type of memory error happens when a person fails to remember the source or origin of a memory. They may remember the information correctly but are unable to recall where or from whom they learned it. Prospective memory error: This type of error occurs when a person fails to remember a planned activity or intention in the future. #Step 2: Analyze Roberto's situation#

In this example, Roberto correctly remembers the juicy gossip, however, he fails to remember that Rachel was the person who initially passed the gossip onto him. This indicates that Roberto is having trouble recalling the source of the information. #Step 3: Identify the correct type of memory error#

Considering the description of each memory error and analyzing Roberto's situation, we can deduce that the error Roberto has made is a source-monitoring error. He is unable to recall the origin of the gossip, which led to him mistakenly telling it back to the person who had told him in the first place. #Step 4: Choose the correct answer#

Based on our analysis, the correct option is: C. made a source-monitoring error.

Key concepts

Source-monitoring error

Sometimes we might remember information accurately, but we can't recall where or from whom it came. This is known as a source-monitoring error. Our brain has the task of not only storing the information but also tracking its source. However, when this link breaks, we may misattribute the source.

It often happens in situations where we encounter similar information from multiple sources or in similar contexts. For example, you might hear a piece of gossip from a friend and later retell it, forgetting who first shared it with you.

This can be awkward, like in Roberto's case, where he retold the juicy gossip to Rachel, forgetting she was the original source. To avoid source-monitoring errors, it helps to pay closer attention to who is telling you stories or facts and mentally tag them with their sources as neatly as possible.

Misinformation effect

The misinformation effect occurs when our memories are altered by misleading information we encounter after an event. When we experience an event, our memory of it is like a fragile clay sculpture. It can be shaped and misshaped by subsequent information. This post-event information can interfere with what we originally saw or knew, making it difficult to distinguish between real memories and influenced ones.

For instance, if you're told incorrect details about an event you witnessed, these new details could sneak into your memory, altering what you think you saw. The misinformation effect is a critical concept in understanding how eyewitness testimonies can sometimes be unreliable.

It's important to be aware that our memories are not photographic replicas of events. Instead, they are reconstructed, which opens them up to change and error.

Reality-monitoring error

Reality-monitoring errors occur when we confuse memories of real events with memories of imagined events. Our brain processes both types of memories, but sometimes the line blurs. This is when reality-monitoring errors manifest, and we struggle to determine what was a factual occurrence versus what might have been imagined.

Think of times when you dream vividly and later recall those dreams as if they were actual experiences. The same thing can happen with daydreams or plans we think about extensively. For example, you might tell someone you did something you actually only thought about doing.

A tip to mitigate these errors is to consciously take note of physical signs and sensory details in memories that indicate reality, ensuring our recollections are based in the real world.

Prospective memory error

Prospective memory errors are common mishaps involving forgetting to execute intentions in the future. This happens when we plan to do something later but, when the moment arrives, completely forget to carry out the task. Prospective memory is like a mental to-do list intersected with time.

Examples include forgetting to send an email after you finish your workday or failing to turn off the oven after cooking a meal. These errors can significantly disrupt daily life if they occur frequently.

• Set reminders in phones or calendars.
• Create visual or physical cues, like placing objects in certain places as reminders.
• Develop habits or routines surrounding tasks you frequently need to remember.

With these strategies, it becomes easier to overcome prospective memory errors, keeping your future tasks on track.
