This study sought to find out whether the effect of positive mood on familiarity also transfers to déjà vu. It was hypothesized that people with a higher positive affect will be more likely to commit errors in a memory judgment task, and subsequently experience more déjà vus in a lab study. 42 participants of both sexes with a mean age of 23 participated for course credit or voluntarily. We used a 2 x 2 experimental research design with a mood induction (positive and neutral) and a computer task with pictorial stimuli; assignment to the mood conditions was random. The dependent variables were performance at a memory test and déjà vu occurrence. Independent variables were level of positive affect and processing style (deep or shallow). While we did not find that people with a higher positive affect were less accurate in the memory test, we found that more positive people were more likely to experience déjà vu. We concluded that the results of the present study could shed new light on previous studies but urge their replication with a larger sample size.

Research Objectives and Topics
This study aims to investigate the relationship between positive affect and the frequency of déjà vu experiences, testing whether individuals with higher levels of positive mood are more prone to memory judgment errors and déjà vu phenomena in a controlled laboratory setting.
- The influence of mood induction on déjà vu frequency.
- Cognitive mechanisms of déjà vu (familiarity vs. source monitoring).
- Impact of processing styles (deep vs. shallow) on memory accuracy.
- The role of positive affect as a modulating variable in cognitive tasks.
- Empirical verification of the link between happiness and perceived familiarity.
Excerpt from the Book
The impact of Affect on Déjà vu: Does Happiness provoke Déjà vu?
Déjà vu, that particular funny feeling that we get when we think that we have seen or experienced something before despite disconfirmatory evidence, is familiar to most of us. Descriptive studies have shown that approximately two thirds of all people have experienced at least one déjà vu in their life (Brown, 2003).
One of the pioneering researchers in the field of déjà vu was Gerard Heymans, a Dutch scholar who lived more than a hundred years ago. In his studies from 1904 and 1906 he collected survey data about possible predisposing factors such as personality traits. Some of his conclusions were later confirmed using advanced statistical methods (Sno & Draaisma, 1993), including the hypothesis that a “reduction of psychological energy” caused by an episode of mental or physical effort coincides with déjà vu occurrence. Since then, many more studies sought to investigate this fascinating phenomenon. In a meta-analysis déjà vu was found to be most frequent in young adults, and declines with age. Educated, liberal and well-traveled individuals appeared to experience déjà vu more often (Brown, 2003).
Summary of Chapters
1. Method: This chapter details the experimental design, including participant demographics, the materials used for mood induction and cognitive testing, and the systematic procedure followed during the study.
2. Results: This section presents the empirical findings regarding the relationship between positive affect, test accuracy, and the frequency of déjà vu occurrences among the participants.
3. Discussion: This chapter interprets the research results in the context of existing theories, addresses the success of laboratory-based déjà vu induction, and suggests future directions for research including larger sample sizes and negative mood conditions.

Frequently Asked Questions
What is the fundamental focus of this research?
The study investigates whether positive mood acts as a catalyst for déjà vu experiences and memory judgment errors in healthy individuals.
What are the core research themes?
The core themes include the impact of emotional states on cognitive processing, memory accuracy, and the phenomenon of déjà vu.
What is the primary goal of the study?
The goal is to determine if individuals with higher positive affect are more susceptible to experiencing déjà vu and if this is modulated by their processing style.
Which scientific method was utilized?
The researchers employed a 2 x 2 experimental design, involving mood induction (positive vs. neutral) and processing tasks (deep vs. shallow) to measure cognitive performance.
What does the main body of the work cover?
It covers historical context of déjà vu, the formulation of hypotheses, the methodology of the lab experiment, statistical analysis of the data, and an evaluation of the results against psychological theory.
Which keywords best characterize the work?
Key terms include déjà vu, positive affect, memory accuracy, cognitive processing, and experimental research.
How was the mood of participants controlled?
Participants watched specific videos to induce either a positive or neutral mood and filled out autobiographical questionnaires to maintain their emotional state throughout the session.
What did the results reveal about deep processing?
Deep processing led to higher accuracy rates in the memory test compared to shallow processing, validating the efficacy of the test design.
Did the researchers confirm the link between positive affect and déjà vu?
Yes, the data supported the hypothesis that individuals in the high positive affect group were more likely to report déjà vu experiences.
What is the main limitation noted by the author?
The primary limitation is the small sample size, which necessitates replication of the study to ensure more robust and generalized results.
