Dèjà Vu in Psychiatric and Neurosurgical Patients

An early Dutch study of déjà vu experiences

“…These personality traits -in Heymans' view indications of 'psychological instability'would seem to increase the vulnerability for conditions that reduce 'psychological energy'. These observations concur with the more recent findings of Richardson & Winokur (1967). In a group of psychiatric patients, these authors noted that deja vu experiences occurred significantly more frequently in the personality disorders and mixed diagnoses categories (P < 0-05).…”

Deja Vu and Depersonalization in Normal Subjects

A review of the déjà vu experience.

“…With respect to education level, Chapman and Mensh (1951) found a systematic increase in déjà vu incidence across years of education (education years: < 9 = 20%, 9–12 = 44%, 13+ = 50%). Richardson and Winokur (1967)found a similar relationship between years of education and déjà vu incidence in both neurosurgery (education years: < 9 = 12%, 9–12 = 42%, 13+ = 68%) and psychiatric (education years: < 9 = 23%, 9–12 = 46%, 13+ = 56%) patients. Comparing five levels of educational achievement, Palmer (1979) noted the lowest incidence of déjà vu (48%) at the bottom rung (grade school only) and the highest incidence of déjà vu (81%) among those with a graduate degree.…”

“…Chapman and Mensh (1951) discovered that people who did not travel had an 11% incidence of de ´ja `vu, whereas those who made one to four trips a year had a 31% incidence, and people who took five or more trips per year had a 32% incidence of de ´ja `vu. Richardson and Winokur (1967) found a similar relationship with both neurosurgery (11% incidence for nontravelers, 41% among those making one to four trips a year, and 44% for those taking five or more trips per year) and psychiatric patients (33% for nontravelers, 48% among those making one to four trips, and 45% for those taking five or more trips per year). Thus, those who travel have more de ´ja vu experiences than those who do not, but the amount of travel seems to make little difference.…”
