First Impression01:09

First Impression

421
First impressions play a crucial role in social perception, shaping how individuals assess others in professional, academic, and interpersonal contexts. Psychological research highlights the significance of cognitive biases, such as the primacy and recency effects, which influence how people interpret and recall information.The Primacy Effect and Cognitive AnchoringThe primacy effect describes the tendency for initial information to impact judgment disproportionately. When individuals encounter...

Serial Position Effect01:03

Serial Position Effect

710
The serial position effect is a cognitive phenomenon where individuals are more likely to recall the first and last items in a list compared to those in the middle. This effect is divided into the primacy effect and the recency effect. The primacy effect is observed when the initial items in a list are remembered better. This occurs because these items are rehearsed more frequently or receive more elaborative processing, allowing them to be encoded into long-term memory more effectively. For...

Interference and Decay01:16

Interference and Decay

605
Forgetting is a complex cognitive phenomenon influenced by several factors, among which interference and decay are particularly prominent. These processes explain why individuals often struggle to retrieve specific information from memory, leading to lapses in recall that can be observed in everyday situations.
Interference occurs when competing memories hinder the retrieval of particular information. It can be classified into two types: proactive and retroactive interference. Proactive...

Immunological Memory01:23

Immunological Memory

12.3K
Immunological memory, a pivotal pillar of the adaptive immune system, is responsible for the body's ability to remember and respond more swiftly and effectively to previously encountered pathogens. This remarkable feature is what makes vaccines so effective in preventing diseases.
What is Immunological Memory?
Immunological memory is an integral function of the immune system that allows it to recognize and react more rapidly and effectively to pathogens previously encountered. This feature...

Implicit Memories01:24

Implicit Memories

622
Implicit memories, also known as non-declarative memories, are long-term memories that function outside of conscious awareness. These memories influence behavior and skills without explicit knowledge. This type of memory is evident in tasks like playing tennis, snowboarding, and texting. Implicit memory has three subsystems: procedural memory, conditioning, and priming. This type of memory is essential in various activities, from everyday tasks to specialized skills.
One key aspect of implicit...

Higher Mental Functions of Brain: Learning and Memory

2.2K
Memory is one of the most vital higher mental functions of the brain. Memory is closely related to learning because it enables us to retain information and experiences from our past to use them in our present life. It also helps us to remember facts, events, and skills, such as riding a bike or swimming. There are two types of memory — declarative memory, which involves memorizing facts or events, and procedural memory, which enables us to remember how to do something like writing or...

Summary
This summary is machine-generated.

Online users exhibit a memory effect in their selection and rating behaviors, influencing preference evolution. This memory duration follows a power-law distribution, unlike random behavior.

Area of Science:

  • Computational Social Science
  • Behavioral Economics
  • Data Science

Background:

  • Understanding online user preference evolution is crucial for enhancing online services and user behavior analysis.
  • User ratings serve as a key indicator of preferences in many online systems.

Purpose of the Study:

  • To uncover and model the memory effect in online users' selecting and rating behaviors.
  • To quantify the duration of this memory and its distribution.
  • To develop a flexible preference model that can capture varying memory strengths.

Main Methods:

  • Analysis of two benchmark datasets from online systems.
  • Identification and characterization of memory effects in sequential user behaviors (object selection and rating).
  • Development of a preference model using a Markovian process for selection behavior, with rating behavior dependent on selection.

Main Results:

  • Discovery of a significant memory effect in both users' object selection and rating sequences.
  • The memory duration follows a power-law distribution, indicating a higher probability of long-duration memories than random (exponential) distributions.
  • The proposed preference model, with minimal parameters, can accurately regenerate diverse memory duration distributions, from strong (power-law) to weak (exponential).

Conclusions:

  • User preference evolution is significantly influenced by a memory effect, deviating from purely random behavior.
  • The developed preference model provides a robust framework for understanding and simulating user memory in online systems.
  • The findings have implications for personalized recommendations, user interface design, and understanding long-term user engagement.
