Summary
Déjà vu experiences, a dissociative phenomenon, are difficult to study empirically. Current research on this familiarity with the past is inconsistent and inconclusive, requiring further investigation.
Area of Science:
- Psychology
- Neuroscience
- Psychiatry
Background:
- Déjà vu is a dissociative phenomenon characterized by an inappropriate sense of familiarity.
- Understanding the empirical basis of déjà vu is crucial for psychiatric and neurological research.
Purpose of the Study:
- To review and summarize empirical studies on déjà vu experiences.
- To assess the significance and limitations of current research on déjà vu.
Main Methods:
- Systematic review of empirical studies on déjà vu.
- Analysis of findings regarding the phenomenon's characteristics and prevalence.
Main Results:
- Empirical findings on déjà vu experiences are largely inconsistent and inconclusive.
- Methodological and conceptual limitations significantly impact the significance of existing research.
Conclusions:
- Current empirical research on déjà vu has limited significance.
- Further research is needed to explore the qualitative features and clinical psychiatric relevance of déjà vu experiences.

Extrasensory perception, or ESP, suggests the ability to perceive events beyond the conventional senses of sight, hearing, and touch. Parapsychologists, who research ESP and related psychic phenomena, categorize ESP into three main types: precognition, telepathy, and clairvoyance.
Precognition involves foreseeing future events, such as predicting an accident before it happens. An example of precognition could be someone dreaming about a specific event, like a car crash, which then occurs...

An empathetic person makes an emotional connection with others and feels compelled to help (Batson, 1991). Empathy can be expressed in several ways, including cognitive, affective, and motor.

Because in these group settings, the individual no longer sees themselves as an individual anymore, disinhibiting their behavior and personal restraint.

01:37Reason and Intuition
5.9K
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...

Eyewitness memory refers to the recollection of events by someone who has directly witnessed them, often serving as critical evidence in legal settings. This type of memory is commonly used in criminal cases where a witness describes details like a suspect's appearance, clothing, or behavior during a crime. However, despite its perceived reliability, eyewitness memory is prone to significant errors.
One such error is memory distortion, which occurs because human memory does not function...

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...
