Background.Different individuals have alpha waves with different wavelengths. The distribution of the wavelengths is assumed to be bell-shaped and smooth. Although this view is generally accepted, it is still just an assumption and has never been critically tested. When exploring the relationship between alpha waves and personality traits, it makes a huge difference if the distribution of the alpha waves is smooth or if specific groups of alpha waves can be demonstrated. Previous studies have not considered the possibility that specific groups of alpha waves may exist.Methods.Computerized EEGs have become standard, but wavelength measurements are problematic when based on averaging procedures using the Fourier transformation because such procedures cause a large systematic error. If the actual wavelength is of interest, it is necessary to go back to basic physiology and use raw EEG signals. In the present study, measurements were made directly from sequences of alpha waves where every wave could be identified. Personality dimensions were measured using an inventory derived from the International Personality Item Pool.Results.Recordings from 200 healthy individuals revealed that there are three main groups of alpha waves. These groups had frequencies around 8, 10, and 12 waves per second. The middle group had a bimodal distribution, and a subdivision gave a total of four alpha groups. In the center of each group, the degree of extraversion was high and the degree of neuroticism was low. Many small differences in personality traits were found when the centers were compared with one another. This gave four personality profiles that resemble the four classical temperaments. When people in the surrounding zones were compared with those in the centers, relatively large differences in personality traits were found.Conclusions.Specific groups of alpha waves exist, and these groups have to be taken into account when correlations are made to personality dimensions and temperament types. There is a link between alpha waves and personality traits, and this link implies that there is an underlying relationship. To explain the nature of this relationship, there are two hypotheses that can be applied. One of these deals with the general organization of the forebrain and the other explains why the brain generates alpha waves.

People are able to assess some personality traits of others based on videotaped behaviour, short interaction or a photograph. In our study, we investigated the relationship between body odour and the Big Five personality dimensions and dominance. Sixty odour samples were assessed by 20 raters each. The main finding of the presented study is that for a few personality traits, the correlation between self–assessed personality of odour donors and judgments based on their body odour was above chance level. The correlations were strongest for extraversion (.36), neuroticism (.34) and dominance (.29). Further analyses showed that self–other agreement in assessments of neuroticism slightly differed between sexes and that the ratings of dominance were particularly accurate for assessments of the opposite sex.

This study explores the relationship between “Big Five” personality dimensions and implicit prejudice towards two groups: (1) homosexuals and (2) elderly people. We employed the NEO PI-R personality inventory to register basic personality dimensions, the Implicit Association Test (IAT) to measure implicit prejudice, and a semantic differential and the Fraboni scale to assess explicit prejudice. Results of the correlation and multiple regression analyses indicated that implicit prejudice toward homosexuals was related to Openness to Experience, while implicit ageism was related to Agreeableness. More precisely, people who obtained lower scores on these personality dimensions were more likely to hold implicit prejudice towards members of these stigmatized groups. We demonstrated that the relationship between personality and implicit prejudice could not be reduced to the relationship of personality traits with the explicit measures of prejudice. We compared these findings with the previously obtained pattern of results for explicit prejudice measures and discussed their implications for a theoretical distinction between implicit and explicit prejudice constructs.

To cope with changing and unfamiliar situations, individuals process novel information and integrate this information into internal models that were formed through previous experiences. We propose that the continuum of the degree to which people update these internal models when encountering novel information is central to personality dynamics. Personality traits therefore arise at both ends of this continuum. Personality dimensions and behavioral manifestations (such as those reflected in liberal and conservative political thought) are classified at different points along this continuum, as well as according to the availability and flexible situational accessibility of internal models. Our model is rooted in neurobiological evidence (interactions of large-scale brain networks in particular) and shows strong parallels with models of basic animal personality traits. The model thus permits to explain both personality traits and personality dynamics, including phasic and stable adaptations to environmental conditions. Moreover, the model sheds light on the development of personality and its origins through phylogenetic and ontogenetic time.

The relationship between occupational preferences and personality traits was examined. A randomly chosen sample of 735 students (age range = 17 to 23 years; 50.5% male) in their last year of high school participated in this study. Participants completed Cattell's Sixteen Personality Factor–5 Questionnaire (16PF–5 Questionnaire) and the Kuder–C Professional Tendencies Questionnaire. Initial hierarchical cluster analysis categorized the participants into two groups by Kuder–C vocational factors: one showed a predilection for scientific or technological careers and the other a bias toward the humanities and social sciences. Based on these groupings, differences in 16PF–5 personality traits were analyzed and differences associated with three first-order personality traits (warmth, dominance, and sensitivity), three second-order factors (extraversion, control, and independence), and some areas of professional interest (mechanical, arithmetical, artistic, persuasive, and welfare) were identified. The data indicated that there was congruency between personality profiles and vocational interests.

This study focused on the idea that there are predictable differences between those individuals who opt for Scientific rather than the Commerce/Practitioner jobs and consulting assignments. A total of 2278 adults from a variety of occupations completed three validated questionnaires: the first assessed the behavioural tendency of an individual when one is exposed to stress and which could derail one’s business career (HDS: Hogan Development Survey); the second the values and preferences that indicate work motivation (MVPI: The Motives, Values and Preferences Inventory), and the third, seven bright-side personality factors (HPI: Hogan Personality Inventory). The MVPI measured interests in scientific and commercial/enterprising activities. Correlations, regressions and SEM indicated both similarities and differences in the relationship between personality traits and values. Bright-side personality traits accounted for more the variance for those interested in Science while dark-side traits accounted for more variance for those interested in the Commerce. The biggest difference occurred in Inquisitiveness (Curiosity, Openness to Experience) which was much higher for those interested in science. Implications for personnel selection, job-fit and promotion were discussed.

Abstract Introduction Insomnia is a common sleep disorder in adults. Primary Insomnia (PI) can be specified in cases where the insomnia symptoms cannot be overtly attributed to medical, psychiatric, or environmental reasons. Although the underlying predisposing causes of insomnia are unclear, one possible contributing factor may be personality traits. To date no consensus on the relationship between insomnia and personality has been determined, although many studies have found a general association with neuroticism. To better explore these associations, this study compared NEO Five Factor Model (FFM) personality traits with measures of subjective sleep in PIs and Good Sleeper (GS) controls. Methods Nine PI and nine GS matched for age, sex, and education were studied. Each participant was administered the Insomnia Severity Index (ISI), Pittsburgh Sleep Quality Index (PSQI), and NEO FFM. Participants also completed a sleep diary for 1-week. ANOVAs compared PI vs GS on ISI, PSQI, NEO FFM, and 7-day averaged data from the sleep diary. Lastly, sleep variables were collapsed across groups and Pearson correlations were run to explore the relationship between sleep and personality. Results PIs (4M/5F, age=39.6+/-10.1, education=16.0+/-1.7) and GSs (4M/5F, age=38.6+/-7, education=15.1+/-1.5) showed significant differences in ISI (p<.001) and PSQI (p<.001) total scores. Additionally, the groups differed on diary measures of total sleep (p=.001), sleep efficiency (SE: p<.001), sleep latency (p=.005), and wake after sleep onset (p<.001). On the NEO FFM only the Agreeableness domain was found to differentiate the two groups (p=.004). Pearson correlations found significant negative relationships for Agreeableness with ISI (r= -.625/p=.006), PSQI (r= -.611/p=.007), and a significant positive relationship with SE from the sleep diary (r=.602/p=.008). Conclusion In a small but well-matched study of PI and GS, significant differences in Agreeableness on the NEO FFM were observed. Lower levels of agreeableness were associated with poorer sleep on the ISI and PSQI, and lower SE on the sleep diaries. Unlike other published reports this study did not find a relationship between insomnia and neuroticism, which may reflect the use of a well-screened Primary Insomnia sample with limited comorbidities. Future research should determine if other insomnia subtypes (e.g., psychophysiological, paradoxical insomnia) are associated with different personality profiles. Support (if any):

Research on self-reported executive functioning (EF) and personality has largely focused on normative personality traits. While previous research has demonstrated that maladaptive personality traits are associated with performance-based EF, the literature examining the relationship between these traits and self-reported EF is limited. The current study examined the relationship between multiple domains of self-reported EF (Barkley Deficits in Executive Functioning Scale) and both normative (The International Personality Item Pool–NEO–120 Item [IPIP-120]) and maladaptive (Personality Inventory for DSM-5–Short Form [PID-5-SF]) personality traits in an undergraduate student sample ( n = 354). Similar to past research, relationships were largest across EF domains for both measures related to neuroticism (i.e., IPIP-120 neuroticism and PID-5-SF negative affectivity) and conscientiousness (i.e., IPIP-120 conscientiousness and PID-5-SF disinhibition). Normative personality traits generally accounted for greater variance in EF when examined alone and were also generally associated with greater incremental validity when compared with maladaptive personality traits. However, multiple regression analyses indicated that maladaptive personality traits added unique predictive variance above and beyond normative personality traits in their association with multiple domains of EF. These results highlight the utility of assessing both normative and maladaptive personality traits as well as multiple domains of EF to more fully understand the relationship between personality and EF.

This study examines the relationship between speech characteristics and personality traits by drawing on pseudo-naturalistic conversations and on personality dimensions identified by the Myers–Briggs Type Indicator (MBTI) model which assesses four personality dimensions of introversion-extroversion, sensing-intuiting, thinking-feeling, and judging-perceiving. The speech of 30 participants was recorded and transcribed, after which a number of speech features including pitch, loudness, response time (i.e., how fast one responds to a prompt), speech rate, and discourse markers were extracted and analyzed. Results show that several speech features correspond to different personality dimensions. Specifically, speech rate as measured by words per minute reveals significant differences between judging individuals and perceiving individuals (perceiving individuals speak faster than judging individuals); there is a significant difference in response time for extroverts and introverts (extroverts respond faster); a significant difference is observed in loudness between judging and perceiving individuals (judging individuals are louder). The frequency of discourse markers is significantly higher for intuiting individuals than sensing individuals. The study discusses these findings in further inquiring the relationship between language and personality.

AbstractBullying and cyberbullying are highly prevalent in today’s society. However, the personality profiles of different roles involved in this phenomenon remain little known. This study aims (1) to examine the association between bullying and cyberbullying in adolescents; and (2) to analyze the relationship between bullying and cyberbullying in terms of the domains and facets of the five-factor model (FFM). A total of 910 adolescents aged 12 to 19 years old participated. They were administered self-report assessments of aggression and victimization in bullying and cyberbullying, as well as the JS-NEO-S questionnaire. The results provide evidence of co-occurrence between bullying and cyberbullying (p < .001). We observed higher neuroticism in victims and aggressor-victims, higher openness in victims, higher agreeableness in victims and non-aggressor non-victims and higher conscientiousness in non-aggressor non-victims as compared with the rest of the groups (p < .001). Comparison of the four cyberbullying groups showed that cybervictims score higher in neuroticism and openness, cybervictims and non-cybervictims non-cyberaggressors score higher in agreeableness and non-cybervictims non-cyberaggressors score higher in conscientiousness (p < .001) In conclusion, this study provides a broad, systematic view of the personality traits associated with different roles implicated in traditional bullying and cyberbullying.

Background: Human choices and decisions are highly affected by some psychological and personality traits. These psychological characteristics may also be related to the choice of delivery type. Therefore, the present study aimed to investigate the relationship between personality dimensions and choice of delivery type (cesarean section or normal) in pregnant women referred to Abolfazl hospital in Minab county, Iran, in 2018. Materials and Methods: This is a cross-sectional descriptive study. The statistical population consisted of all pregnant women referred to Abolfazl medical center in 2008 in Minab, 118 of whom were selected by convenience sampling. The NEO Five-Factor Inventory (NEO-FFI) was used to collect the data. Results: There was a significant difference in the choice of delivery type (normal and cesarean section) in pregnant women with extraversion and conscientiousness personality traits (P value <0.05). The mean extraversion and conscientiousness scores were higher in patients who tended to have a vaginal delivery than in those who had chosen cesarean section. Conclusion: The results of the present study show that personality traits can determine the type of delivery by creating specific moods; therefore, considering the high level of complications of cesarean section (CS) and high CS rate in Iran, we can change people’s attitudes and play a role in reducing the number of CSs through long-term training.
