Questions and Answers

What is the primary function of episodic future thinking?

Study Notes

Lecture 14: Future Thinking

Cognitive Neuroscience lecture on October 24, 2024
The lecture outlines the concept of future thinking, revisits a patient case study, explores mind-wandering.
It further discusses the types of future thinking, brain regions involved in episodic future thinking, and prospective memory.
Also includes announcements and review questions.

Memory

Memory is categorized into:
- Memory for the past (e.g., episodic, semantic)
- Memory for the present (e.g., sensory, short-term, working)
- Memory for the future

Patient K.C.

K.C. exhibited difficulty imagining the future, stating that he did not think about his future.
When asked about the future, K.C. responded by saying, "I guess so. I don't really think much about the future."
This was in response to the question "Do you feel hopeful about the future?"

Episodic Memory

Endel Tulving described mental time travel as autonoetic consciousness.
This concept applies to remembering the past and the future. (The ability to project oneself into the future, similar to remembering the past).
Patient K.C.'s difficulties highlight the crucial role of episodic memory in simulating the future.

K.C. Interview

K.C. struggled to describe his mental state when thinking about the future.
He reported a blank state, implying a lack of episodic future thinking abilities.
K.C.'s responses highlighted his difficulty imagining the future, further emphasizing the link between episodic memory and future thinking.

What does this tell us?

Patients with hippocampal/MTL damage lack episodic memory of the past and the future
They're also unable to construct fictional scenarios of the future.

Mind Wandering

Humans spend 30-50% of their waking hours daydreaming or mind-wandering.
Mind-wandering is more common during non-effortful tasks.
Mind-wandering involves self-generated thoughts that may include past, present, and future scenarios.
People with hippocampal amnesia exhibit different daydreaming patterns, and more present-oriented thoughts than healthy participants.

Four Forms of Future Thinking

Prediction: Assessing the likelihood of future events.
Simulation: Creating mental images of future events.
Goal Setting: Defining intentions and future objectives.
Planning: Outlining steps needed to achieve goals.

Episodic Future Thinking

The capacity to envision and mentally simulate personal future events
Semantic memory serves as a framework, and episodic memories fill in the details.
This process allows for imagined future events in the first person perspective.
Similar brain regions are active during episodic future thinking and episodic memory retrieval.

Brain Regions in Episodic Future Thinking

The hippocampus and medial temporal lobe (MTL) are critical for episodic future thinking.
Dorsolateral prefrontal cortex has increased activity during episodic future thinking as well.

Prospective Memory

The ability to remember intentions or future tasks.
Can be divided into time-based (remembering to do something at a specific time) or event-based (remembering to do something during a specific event).
Two supporting mechanisms for prospective memory are sustained and bottom-up attentional control.

Announcements

Extra credit opportunities are available through SONA and Jeopardy.
Additional credit can be rewarded for attendance at 12 or more sections.
Homework 6 is due on Thursday, October 31st.

Review Questions

K.C.'s view of the future and episodic amnesia patients' daydreaming differences are presented.
The role of the hippocampus in episodic future thinking is discussed.
Four types of future thinking (prediction, simulation, goal-setting, planning) were also described to assess their differences from each other.
The details of brain activity for episodic memory retrieval vs. episodic future thinking are explained.
prospective memory, the two types, and its connection to (top-down and bottom-up) attentional control topics were also assessed.
