Dream Recall Frequency and Dream Detail as Mediated by Personality, Behavior, and Attitude

Many studies investigated how personality, behavior, and attitude mediate dream recall, but few distinguish between measures of dream recall frequency: the number of dreams experienced in a specified time frame and dream detail: individual ratings of vividness or detailed content of dreams. This study compared undergraduates' (n = 173) self-reported dream recall frequency, and dream detail, with behaviors, attitude toward dreaming, and scores on scales of Extraversion/Introversion and Type A/B. Dream recall frequency and dream detail manifested different patterns of association in relation to behaviors, attitude and personality. Dream recall frequency was associated with the frequency of experiencing emotionally disturbing dreams and trying to interpret dreams, while detail of dreams was associated with positive attitude toward dreaming and Type B personality. Although males and females both held positive attitudes toward dreaming, females experienced more emotionally disturbing dreams and felt unable to control their dreams. Interactions between personality and gender emerged for behaviors associated with dreaming. Researchers are encouraged to differentiate between dream recall frequency and dream detail.     

Gender role conflict and the process and outcome of dream work with men.

The current study evaluated how men with variable levels of gender role conflict responded to single-session, therapist-facilitated dream work using the C. E. Hill (1996, 2004) model of dream work. Overall, men reported positive benefits from participating in the dream session, similar to data in other studies. Men who reported higher gender role conflict on the Gender Role Conflict Scale discussed related gender role conflict themes during dream work, although gender role conflict was not related to session outcome. Reasons for these results are explored, and ideas for future research are suggested. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

The persistence of gender stereotypes in the face of changing sex roles: Evidence contrary to the sociocultural model

Prevailing explanations for gender differences rest upon the sociocultural model, which treats personality as a consequence of socialization for social roles. Though sex roles and attitudes toward them have changed dramatically in the United States over the past three decades, a review of 18 longitudinal studies of gender stereotypes and self-ratings shows stability in perceptions of sex-typed personality traits. Our study of 3600 students surveyed in six waves from 1974 to 1991 also shows stability and even a slight increase in sex typing. This accumulating evidence is inconsistent with the sociocultural explanation. It is more consistent with the currently emerging sociobiological research that holds gender differences reflect innate differences between the sexes resulting from their different reproductive strategies. We conclude that valid social psychological explanations for gendered personality traits cannot rest upon sociocultural models alone but must include interaction of this unchanging genetic underlay with changeable social structures and processes.     

Typical dreams experienced by Chinese people.

The present study investigated the prevalence profile and frequencies of typical dream themes experienced by Chinese people. The Typical Dreams Questionnaire was administered to 348 university students in Hong Kong. The results demonstrated that the prevalence profile of the typical dream themes for the Chinese participants resembled those profiles previously reported by Western studies. In addition, the present study found large positive correlations between the rank-ordered prevalence and frequency scores of the typical dream themes. This implied that the most prevalent themes were also more likely to be the most recurrent themes and vice versa. Therefore, typical dream themes not only are shared by many people but also tend to be repeatedly experienced within a person. This result supports the postulation that typical dreams are distinguished by both their universality and recurrence. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Personality and Dream Recall Frequency: Still Further Negative Findings

In order to investigate the relationship between dream recall frequency and personality, 116 college undergraduates kept a dream log for 21 consecutive nights and completed self-report measures assessing fantasy-proneness, psychological absorption, and imaginative involvement. Consistent with most previous literature in this area, with one exception, there were no significant associations found between dream recall and the personality measures. The one exception to this pattern was for fantasy proneness and this correlation was of a small magnitude and only obtained for women. We conclude that dream recall frequency is largely independent from stable personality traits and can better be understood in terms of expectancy and attitudinal factors.     

Explaining the gender difference in dream recall frequency.

A recent meta-analysis showed a substantial and robust gender difference in dream recall frequency of medium effect size, that is, women tend to recall their dreams more often than men. The question arises as to what factors might explain this difference. Two previous studies indicate that interest in dreams plays an important role. The present study found a significant effect of frequency of nocturnal awakenings and interest in dreams on the gender difference in dream recall frequency. In addition, neuroticism and depressive mood were associated with the gender difference on the aspects of a dream recall scale and interest in dreams. Longitudinal studies are necessary to validate the present findings, especially regarding their causality. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Stereotypical Gender-Based Emotions Are Not Detectable in Dream Reports

This study reports on the number of feelings evoked in men and women by their dream characters as well as on the relative frequency of different kinds of feelings. Thirty-five subjects recorded 320 dreams over a two-week period, submitted dream reports and a dream log of all characters that appeared in their dreams as well as any feelings involving the characters. We found that feelings were pervasive in dreams and that they were evoked by over 80% of a subject's dream characters. Further, negative and positive emotions were balanced for both men and women. We found no significant differences in the number or in the profile of feelings in men and women's dreams. The reasons for this are discussed in terms of a continuity hypothesis across dream and wake states or, on the contrary, that feelings expressed in dreams may be independent of learned gender differences.     

Paranoia in dreams and the classification of typical dreams.

The present study was geared toward expanding the previous evidence for the thematic similarities between dreaming and psychosis. Themes derived from delusions that characterize psychotic and schizophrenia-spectrum disorders, together with the modified Typical Dream Questionnaire, were administered to 280 Chinese participants from Hong Kong. These delusional themes served as some continuous variables for evaluating the degree to which the narrative contents of dreaming can be compared with those of psychotic and schizophrenia-spectrum disorders. It was found that delusions of various types, with various levels of bizarreness, could be observed in dreams. This was particularly true for themes involving paranoid suspiciousness, such as blaming others for making troubles and feeling that others are not giving proper credit for one’s achievements, which were dreamed by a majority of the participants. The current findings generated by the exploratory factor analyses precisely replicated Yu’s (2009) previous delusional model that classified dream themes into the Ego Ideal, Grandiosity, and Persecution categories. Moreover, the present study expanded the Ego Ideal category, developed measures for assessing the delusional inclination during dreaming, and discussed the reciprocal, triadic dynamics between the three major categories of dream themes.

Content Analysis of German Students' Dreams: Comparison to American Findings

Studies have demonstrated that general dream characteristics, such as gender ratio and familiarity of dream characters, frequency and type of social interactions and settings, and gender differences (e.g., heightened physical aggression in men's dreams), are very stable over time and across different populations. The present study included 537 dreams of 106 women and 39 men (German students). The results confirmed earlier findings regarding the stability of general dream characteristics and gender differences. Only the gender difference regarding the gender ratio of dream characters has not been replicated; this finding might be explained by the relationship status (single vs. stable partnership) of the dreamers. The comparison of large dream samples may shed light on the similarities and differences between the inner worlds of people of different countries and cultures.     

Direct and Indirect Effects of Five Factor Personality and Gender on Depressive Symptoms Mediated by Perceived Stress

This study was designed to investigate associations among five factor personality traits, perceived stress, and depressive symptoms and to examine the roles of personality and perceived stress in the relationship between gender and depressive symptoms. The participants (N = 3,950) were part of a cohort study for health screening and examination at the Kangbuk Samsung Hospital. Personality was measured with the Revised NEO Personality Inventory (NEO-PI-R). Depressive symptoms were assessed using the Center for Epidemiologic Studies Depression Scale (CES-D). Perceived stress level was evaluated with a self-reported stress questionnaire developed for the Korea National Health and Nutrition Examination Survey. A higher degree of neuroticism and lower degrees of extraversion, agreeableness, and conscientiousness were significantly associated with greater perceived stress and depressive symptoms. Neuroticism and extraversion had significant direct and indirect effects (via stress as a mediator) on depressive symptoms in both genders. Agreeableness and conscientiousness had indirect effects on depression symptoms in both genders. Multiple mediation models were used to examine the mediational roles of each personality factor and perceived stress in the link between gender and depressive symptoms. Four of the personality factors (except openness) were significant mediators, along with stress, on the relationship between gender and depressive symptoms. Our findings suggest that the links between personality factors and depressive symptoms are mediated by perceived stress. As such, personality is an important factor to consider when examining the link between gender and depression.     

Crowdsourcing a Collective Sense of Place

Place can be generally defined as a location that has been assigned meaning through human experience, and as such it is of multidisciplinary scientific interest. Up to this point place has been studied primarily within the context of social sciences as a theoretical construct. The availability of large amounts of user-generated content, e.g. in the form of social media feeds or Wikipedia contributions, allows us for the first time to computationally analyze and quantify the shared meaning of place. By aggregating references to human activities within urban spaces we can observe the emergence of unique themes that characterize different locations, thus identifying places through their discernible sociocultural signatures. In this paper we present results from a novel quantitative approach to derive such sociocultural signatures from Twitter contributions and also from corresponding Wikipedia entries. By contrasting the two we show how particular thematic characteristics of places (referred to herein as platial themes) are emerging from such crowd-contributed content, allowing us to observe the meaning that the general public, either individually or collectively, is assigning to specific locations. Our approach leverages probabilistic topic modelling, semantic association, and spatial clustering to find locations are conveying a collective sense of place. Deriving and quantifying such meaning allows us to observe how people transform a location to a place and shape its characteristics.     

Dream Recall Frequency, Attitude Towards Dreams and Openness to Experience

The question whether personality dimensions explain the interindividual differences in dream recall frequency has often been investigated by dream researchers. The present findings confirm previous research which has shown that traits such as openness-to-experience and thin boundaries correlate substantially with dream recall frequency. However, correlation coefficients are small and are much larger if attitude towards dreams or a scale measuring different aspects of dream recall are considered. Thus, future studies should consider the differentiation between items measuring dream recall and related aspects and items measuring attitudes towards dreams. Schonbar's life-style hypothesis should be revised slightly: not dream recall frequency but attitude towards dreams and the way to deal with dreams are part of a broader life style.     

Interest in dream interpretation: A gender difference.

Although several studies reported a significant effect with regard to the gender difference in an interest in dreams, the generalizability of these studies is limited because mainly students were recruited as participants. In this study, gender differences with regard to interest in dream interpretation as an indicator of interest in dreams in general have been demonstrated in a representative sample. There was, however, a significant age-gender interaction, indicating that interest in dreams might not be a potent variable for explaining gender differences in dream recall. In future studies, the course of interest in dreams over the life span and any associated gender differences should be investigated using carefully designed scales.

Review of The Mind at Night: The New Science of How and Why We Dream.

In this article I review "The Mind at Night: The New Science of How and Why We Dream," written by Andrea Rock. To begin with this book is an exciting journey through modern dream research. Scientific facts, which are skillfully explained, are complemented by personal accounts of well-known researchers in the field obtained through interviews. The diversity of the themes addressed in the book (e.g., sleep and memory, animal research, imaging studies, dream content analysis, consciousness research, creativity, and lucid dreaming) clearly shows the extensive "detective work" the author has accomplished. The major problem I had--as a researcher in this field--was the structure, or the lack of structure, within the book. Because of the way the book is organized, I decided to structure this review along the following themes: REM sleep, REM sleep and dreaming, biology of dreaming, dream content findings, and the integration of dream research into cognitive neuroscience in general. Despite the lack of structure of the book, Andrea Rock has written a wonderful book about modern dream research that is stimulating for researchers as well as for interested lay persons. I recommend it to everyone who is interested in dream research, the old question of the mind-body relationship, or understanding consciousness in general.

Children's Dreams and Nightmares: Emerging Trends in Research.

New manifest content analysis research on children's dreams and nightmares provides insights into how dreaming reveals developmental changes over time. Five culturally diverse research studies were conducted with varied methods for dream collection that included laboratory-collected dreams, as well as written journals, audiotaped dreams, and retrospectively recalled dreams. As children grow older, they are more able to recall dreams, dream narratives increase in length, and dreams are characterized by decreasing levels of passive victimization and have more elaborate character interactions. Age and gender differences in recall, interactions, and gender of dream characters indicate that dream research is a fertile area for studying child development and the changing function of dreams over time.

Personality and Dreaming: Boundary Structure and Dream Content

Prior studies indicate that a personality dimension reflecting thin versus thick boundaries is related to global ratings of dream vividness, amount of emotion, and amount of interaction. In the present study, these relationships were examined by relating scores from the Boundary Questionnaire ( Hartmann, 1991) to dream content among 80 patients seen at a sleep disorders center. Thinness of boundaries was significantly correlated with dream length, vividness, amount of detail, and amount of emotion, and showed a trend towards correlation with aggressive interaction and nightmare-likeness. When dream length was statistically controlled, the relationships between boundary structure and dream content were no longer statistically significant, although amount of emotion and amount of detail showed a trend in the original direction. A principal components analysis was used to identify three factors in the dream content data (eigenvalues > 1.0). The first factor involved dream length, vividness, detail, and emotion; the second involved love/tender interaction and sexual interaction; and the third involved aggressive interaction. Thinness of boundaries showed a significant correlation with only the first factor. We suggest that the trait continuum ranging from thick to thin boundaries is similar to the state continuum running from focused waking thought to dreaming, and that both continua refer to the same aspects of cortical activity.     

Delusions and the factor structure of typical dreams.

The present study was geared toward generating a parsimonious factor model of typical dreams. Moreover, the hypothesis that themes typically manifest in psychotic delusions also prevail in normal people's dreams was examined. The modified Typical Dreams Questionnaire was administered to a sample of 348 university students from Hong Kong. The factor solutions generated by the current analyses indicate that typical dreams can be classified into three primary categories or six subcategories according to the two-tier model. Consistent with the homology between dreaming and psychosis, the first two categories of the upper tier are, in essence, characterized by the two classic psychotic themes—the grandiose and persecutory delusions. The third category of dream themes consists in the distinctive affective experience that can be, one way or another, attributed to the function of the ego ideal.

Dream emotions, waking emotions, personality characteristics and well-being--A positive psychology approach.

The study aimed to discover whether personality characteristics and waking emotions relate to dreaming emotions. There were 123 participants, ranging in age from 17 to 82 years. It was hypothesized that participants with significant positive emotional trait and state ratings in waking life would experience more positive dreams. Data collection utilized diaries and questionnaires, including Hartmann's Boundary Questionnaire, IPIP Emotional Stability Scale, Staats' Hope Scale, Adult Dispositional Hope Scale, and the Positive and Negative Affect Schedule to assess personality and attitudinal characteristics. Participants recorded and rated their waking and dream emotions over a 3-week period. Median correlations between corresponding waking and dream emotions were .58 for positive emotions and .47 for negative emotions. There were also low, but significant correlations between some personality characteristics and participants' tendency to experience positive or negative emotions in dreams.

The Relationship of Dream Content and Changes in Daytime Mood in Traumatized vs. Non-Traumatized Children

The study examined how the mood changes from night to morning, and how dysphoric dream contents associate with this change among children who live in traumatic environment and their controls from peaceful area. The sample consisted of 413 Palestinian boys and girls of 6–15 years of age, the mean age being 11.22 ± 2.64. The participants filled in a seven-day dream diary in which they recorded their recalled dreams every morning. First, the results, confirmed that mood change from evening to morning is a general dream function: age and gender are not related to the change. The mood chance was rather associated with what and whom the children dreamt about. Second, the hypothesis of the trauma group showing less change in dysphoric dream content and in the intensity of negative morning mood across a period of time of seven days was not confirmed. On the contrary, the results showed that both dreams incorporating dysphoric themes and negative morning mood decreased only among children living in traumatic conditions. Third, it was hypothesized that there is a stronger association between presleep negative mood and dysphoric dreams, as well as between the dysphoric dreams and negative morning mood among children living in traumatic environment than among children from peaceful area. Contrary to the hypothesis, results for the trauma group revealed a reverse association between evening mood and dream contents: the more afraid, angry and worried children felt in the evening, the more Happy recreation dreams they reported, and the happier evening mood they reported, the more Threatening stranger dreams they had. However, concurring with the hypothesis, a direct association was found between dysphoric dreams and negative morning mood in the trauma group. The more children dreamt about Threatening strangers, the more afraid, angry and worried they felt in the morning. The discussion proposes a model of the correcting or balancing dream function that is characterized by an reverse assimilation of incorporating evening mood into dreams, and by a direct accommodation of dream content into morning mood.     

Ancient Chinese sex symbols in dreams.

This study aimed to determine how often Chinese people dream ancestral sex symbols and to examine the association between dreaming sexual experiences and the Chinese sex symbols. The modified Typical Dreams Questionnaire with 10 additional items about the Chinese sex symbols was administered to a sample of 107 male and 241 female university students in Hong Kong. Both the prevalence and frequency rates indicated that most ancestral Chinese sex symbols do not constitute prominent dream themes in contemporary Chinese people's dreams. The Chinese genital symbols, caves and towers, were found to be relatively prominent in dreams. However, both symbols were neither positively nor negatively associated with the dream theme sexual experiences and the classical psychoanalytic sex symbols, such as snakes. In contrast, the Chinese symbols of sexual activity, such as birds eating fish, had mild, negative correlations with the dream theme sexual experiences.
