Decision Making01:20

Decision Making

957
Decision-making is a fundamental cognitive process that involves evaluating alternatives and selecting among them. This process can range from simple choices, such as deciding what to wear, to complex decisions, like choosing a major in college or a career path. The complexity of the decision often dictates the approach we use, which can be broadly categorized into two types: automatic and controlled decision-making.
Automatic decision-making is fast, intuitive, and relies on gut feelings...

Association Areas of the Cortex01:21

Association Areas of the Cortex

9.3K
Association areas are regions of the cerebral cortex that do not have a specific sensory or motor function. Instead, they integrate and interpret information from various sources to enable higher cognitive processes such as memory, learning, and decision-making. Some key association areas include the following:
Prefrontal Association Area: This area is located in the frontal lobe and is involved in planning, decision-making, and moderating social behavior. It connects with primary motor areas,...

Associative Learning01:27

Associative Learning

1.3K
Associative learning is a fundamental concept in behavioral psychology, wherein a connection is established between two stimuli or events, leading to a learned response. This process is critical in understanding how behaviors are acquired and modified. Conditioning, the mechanism through which associations are formed, can be divided into two main types: classical conditioning and operant conditioning, each elucidating different aspects of associative learning.
Classical conditioning, also known...

System of Memory01:23

System of Memory

7.3K
Memory is categorized into three major systems: sensory memory, short-term memory (STM), and long-term memory (LTM). These systems differ in their capacity and the duration for which they can hold information. Sensory memory captures raw sensory input from the environment, holding it for just a few seconds or less. For example, on hearing a brief, loud sound, like a car horn honking, the sound seems to linger in the mind for a moment even after it stops. This is an instance of sensory memory...

Working Memory01:24

Working Memory

864
Working memory refers to a combination of components, including short-term memory and attention, that allow an individual to hold information temporarily as we perform cognitive tasks. It is an essential cognitive function that enables the execution of complex tasks such as problem-solving, comprehension, and reasoning. Unlike short-term memory, which simply involves the storage of information for a brief period, working memory involves the active manipulation and processing of this...

Decision Making: P-value Method01:09

Decision Making: P-value Method

6.9K
The process of hypothesis testing based on the P-value method includes calculating the P- value using the sample data and interpreting it.
First, a specific claim about the population parameter is proposed. The claim is based on the research question and is stated in a simple form. Further, an opposing statement to the claim  is also stated. These statements can act as null and alternative hypotheses:  a null hypothesis would be a neutral statement while the alternative hypothesis can...

Area of Science:

  • Cognitive Neuroscience
  • Decision Science

Background:

  • Decision-making relies on past experiences stored in memory.
  • The influence of memory integrity on reinforcement decision-making is under-researched.

Purpose of the Study:

  • To investigate how manipulating memory associations affects reinforcement decision-making.
  • To test the hypothesis that memory distortion alters choice preferences for rewards.

Main Methods:

  • Participants' memory associations were manipulated using false feedback.
  • Decision preferences were assessed in a task involving potential monetary rewards.
  • Memory ratings were measured before and after feedback manipulation.

Main Results:

  • False feedback significantly reduced participants' memory ratings.
  • The manipulation eliminated decision bias observed in participants.
  • Memory undermining altered decision preferences in the reinforcement task.

Conclusions:

  • Reinforcement decision-making is susceptible to alterations in memory.
  • False feedback can disrupt the link between memory and decision preferences.
  • Findings support memory mechanisms like spreading activation in decision processes.
