Factors of home dream recall: a structural equation model

Abstract

SUMMAR Y Previous research has indicated that personality factors such as openness to experience, creativity, visual memory, attitude toward dreams, and sleep behavior is related to home dream recall frequency (DRF). However, a study investigating all areas simultaneously within one sample in order to determine the percentage of variance explained by all variables and to take intercorrelations between the influencing factors into account has not been performed till now. The present study with 444 participants fills this gap. Using several indicators for each of the variables mentioned above, a structural equation model was tested. Although the model fit was satisfying, the four factors which were significantly related to DRF: personality (openness to experience, thin boundaries, absorption), creativity, nocturnal awakenings, and attitude toward dreams, explained only 8.4% of the total variance. As this value is considerably lower than those of studies investigating a single influencing factor and using similar measurement instruments in similar samples, one might speculate about possible expectancy effects in these previous studies, an effect which has been demonstrated for DRF in the laboratory setting.

Right hemisphere neural activations in the recall of waking fantasies and of dreams

“…Furthermore, sample selection is likely to be biased by participants' attitude towards dreams. Indeed, lack of motivation and interest towards dreaming was found to discriminate non-dreamers (Schredl et al, 2003) and can bias any study in the field. Third, given the different perspective of dream and fantasy reports, judges who scored them may have gained implicit knowledge of the narrative transcripts' origin.…”

Nightmares and oxygen desaturations: is sleep apnea related to heightened nightmare frequency?

“…The automatic analyses of the included respiratory parameters were corrected by additional visual scoring, whereas the periodic limb movement indices are based on automatic analysis only. The healthy control groups completed the scales (dream recall frequency and nightmare frequency) as participants in different non-laboratory sleep studies [23,24].…”

“…Healthy controls (nightmare frequency) The sample included 444 persons whose mean age was 23.5±5.7 years (see [24]). There were 376 women and 68 men who were mainly psychology students.…”

Submersion in the experience: The examination of the Tellegen Absorption Scale in an undergraduate university sample

“…Elképzelhetô, hogy az önreflexióra hajlamosabb pszichológushallgatók esetében az abszorpcióra való hajlam inkább a belsô történések megfigyelésében bontakozik ki. Mivel az álomfelidézés gyakoriságában jelentôs szerepet játszanak az álmo-dással kapcsolatos attitûdök, elsôsorban az álmokra való nyitottság (Schredl, Wittman, Ciric, & Götz, 2003), az abszorpciós képesség a lélektani folyamatok iránt érdeklôdô személyek esetében egyfajta belsô katalizátorként hathat az álomfelidézés fokozódására.…”
