Hindsight Biases

Hindsight Biases

Hindsight bias leads you to believe that the event you just experienced was predictable, even though it really wasn’t. In other words, you knew all along that things would turn out the way they did. Can you relate this to the phrase "Hindsight is 20/20" now?

Autobiographical Memory

Autobiographical Memory

Autobiographical memory is a unique type of episodic memory that involves recollecting personal life experiences. It allows individuals to remember significant events from their past, creating a narrative of their lives. One interesting phenomenon related to autobiographical memory is the reminiscence bump. This effect refers to the tendency of adults to recall more events from their second and third decades of life — typically between ages 10 to 30 — than from other periods. This...

Flashbulb Memory

Flashbulb Memory

A flashbulb memory is a highly vivid and detailed memory, often linked to events of significant emotional impact. These memories stand out in contrast to everyday memories due to their clarity and the precision with which they are recalled. The strong emotions associated with the event act as a catalyst, ensuring that specific details, such as one's location, actions, and even peripheral elements, are etched into memory with remarkable accuracy. For example, many people can vividly recall...

Framing Effects

Framing Effects

Information is everywhere and its presentation—such as how and when items are presented—can impact our perceptions and decisions surrounding the info. This broad concept umbrellas framing effects—influences that occur due to the way information is framed in its appearance, whether it’s purely the order or the specific wording of a message. Let’s take a look at numerous ways in which two versions of something can objectively say the same thing, yet we respond in...

Amnesia

Amnesia

Amnesia is a condition marked by long-term memory loss, which impairs the ability to recall past events or create new memories.
The severity and duration of memory loss vary depending on the type and underlying cause. Amnesia is classified into two main types: retrograde and anterograde.
Retrograde amnesia is marked by the loss of memories formed before the onset of the condition. Patients may recall distant past events but often forget those occurring shortly before the incident.
Anterograde...

Reason and Intuition

Reason and Intuition

The human brain processes information for decision-making using one of two routes: an intuitive system and a rational system (Epstein, 1994; popularized by Kahneman, 2011 as System 1 and System 2, respectively). The intuitive system is quick, impulsive, and operates with minimal effort, relying on emotions or habits to provide cues for what to do next, while the rational system is logical, analytical, deliberate, and methodical. Research in neuropsychology suggests that the...

Area of Science:

Neuroscience
Cognitive Science
Computational Neuroscience

Background:

Imagination engages neural circuits shared with present-moment processing.
Understanding animal cognition requires non-linguistic decoding methods.
The hippocampus plays a crucial role in memory and navigation.

Purpose of the Study:

To trace the discovery of forward-sweeping hippocampal theta sequences during deliberation.
To explore the link between hippocampal function and computational models of cognition.
To demonstrate the possibility of accessing imagination in non-linguistic animals.

Main Methods:

Decoding techniques applied to large neural ensembles.
Analysis of hippocampal theta sequences during goal-directed behavior.
Retrospective analysis of scientific discovery and conceptual frameworks.

Main Results:

Hippocampal theta sequences sweep forward to goals during moments of deliberation.
This signal can be recognized and potentially decoded.
The findings support the view of cognition as a computational process.

Conclusions:

Imagination is accessible in non-linguistic animals via neural decoding.
Hippocampal theta sequences provide a neural basis for prospective thought.
Cognition can be understood through the lens of computation and neural dynamics.
