Exploring Personality Profiles as a Source of Phenotypic Diversity in Autistic Children and Adolescents.

This study adopts a person-centered approach to evaluate personality diversity as a source of interpersonal variability in autistic children and adolescents, and how personality subgroup membership relates to variability in autistic characteristics, social-emotional presentations, and parenting outcomes. Latent Profile Analysis was used to analyze 569 parent reports on a child-based Five-Factor-Model personality measure (aged 6-18 years; Mage = 11.8 years, SD = 3.1; 70% boys). Four distinct personality profile groups were identified, showing varying levels in the low to average range of all five personality domains. All groups scored lowest on Extraversion and Emotional Stability. They differed the most in Imagination and the least in Emotional Stability. Group 1 (n = 72) exhibited the lowest mean-level scores on all five domains, whereas Group 4 (n = 90) had the highest domain scores. Group 2 (n = 307) and Group 3 (n = 100) showed more diverse patterns. Group membership was meaningfully associated with variation in characteristics of social interaction and communication, internalizing, externalizing, and attentional problems, psychosocial strengths, and positive parenting strategies. Only modest group differences were found in parenting stress. All groups had similar scores on repetitive and restrictive behaviors. These findings help to better understand and support natural subgroups within the autism phenotype by exploring shared personality attributes.

Representing the Needs of Rural Caregivers of People Living with Alzheimer’s Disease and Related Dementias through User Personas

Abstract Background and Objectives Rural caregivers of people living with Alzheimer’s disease and related dementias (ADRD) face unique caregiving challenges. Current interventions do not address many of the systemic barriers experienced by rural ADRD caregivers, including barriers related to geography, healthcare services access, and financial insecurity. The objective of this study was to gain a deeper understanding of rural ADRD caregivers’ needs, strengths, and strategies in obtaining caregiving support, and to represent these attributes in the form of personas that can be used to design interventions for rural ADRD caregivers. Research Design and Methods In this qualitative user-centered design study, we conducted semi-structured interviews with self-identified caregivers of people living with ADRD in rural areas. Interview data was copied to a virtual whiteboard, and affinity diagramming was used to confirm a priori attributes and yield inductive attributes relevant to rural ADRD caregivers. Attributes were assigned to personas, which were then validated through team-based discussion, consultation with a study advisory board, and review by rural caregivers and community partners. Results Analyses of N=19 interviews yielded seven inductive attributes relevant to rural ADRD caregivers of persons living with ADRD and five distinct personas: Capable Christine, Connected Connie, Isolated Irene, Learning Larry, and Discerning Dan. Personas differed on inductive attributes including financial security, subjective rurality, attitudes, connectedness, and information behavior, including preferences for traditional versus technology-based information seeking. Discussion and Implications The personas identified in the present study can be used as tools to represent and efficiently communicate the intersection and interaction of attributes relevant to designing interventions and technologies to meet the support needs of rural ADRD caregivers.

Latent profile of personality traits for American older adults and its transition during the COVID-19 pandemic.

The impact of COVID-19 on older adults' personality development is essential for emergency management but under-researched. This study seeks to explore the personality profiles of older adults living in the United States and how these profiles transitioned during the pandemic. Longitudinal data were collected from 3,550 adults aged 60 and older who participated in both the 2016 and 2020 waves of the Health and Retirement Survey (61.18% female, mean age 65.85 in 2016). Personality traits were assessed using the Midlife Development Inventory. COVID-19-related experiences including pandemic concerns, restricted healthcare access, financial instability, work challenges, disrupted social connections, and mutual aid behaviors. Latent Profile Analysis and Transition Analysis were used for analysis. Three distinct personality profiles were identified: Well-adjusted, Moderate-adjusted, and Poor-adjusted. About 42% of respondents experienced personality changes during the pandemic. Higher levels of COVID-19 concern were linked to an increased likelihood of transitioning to Poor-adjusted from Moderate (OR=1.06, p<0.05) or Well-adjusted (OR=1.05, p<0.01). Challenges such as healthcare delays and financial hardships hindered transitions from Poor- to Moderate-adjusted (Healthcare delay: OR=0.39, p<0.05; Financial hardships: OR=0.67, p<0.05) but increased the likelihood of Moderate-adjusted individuals transitioning to Poor-adjusted (Healthcare delay: OR=1.46, p<0.05; Financial hardships: OR=1.51, p<0.05). However, Poor-adjusted individuals who provided help to others were more likely to transition to Moderate-adjusted (OR=2.71, p<0.01). Personality transitions during crisis are significant among older adults. Future interventions should focus on addressing traumatic concerns, encouraging helping behaviors, and mitigating healthcare and financial challenges to support older adults' personality development during crisis.

The relationship between personality traits, metacognition and professional commitment in Chinese nursing students: a cross-sectional study.

Professional commitment of nursing students is closely related to the stability of the nursing team. Personality traits and metacognition may be related to professional commitment. We investigate the association between Big Five personality, metacognition, and professional commitment among nursing students, and further explore whether Big Five personality modifies the association between metacognition and professional commitment. From December 2023 to January 2024, a cross-sectional study was conducted among 3631 nursing students from 17 universities in China through the online platform Sojump.com by cluster sampling method and using the general information questionnaire, BFI-44 (Big Five Inventory 44) scale, metacognition scale and professional commitment scale to investigate their demographic data, personality traits, level of metacognition and level of professional commitment. Latent profile analysis was employed to identify optimal categories of personality traits. Multivariate logistic regression was used to analyze the association between the personality traits and professional commitment, as well as metacognition and professional commitment in all participants and participants with different personality traits subgroups, adjusting for potential covariates. Furthermore, the potential mediating role of metacognition between personality traits and professional commitment was also investigated. Three distinct personality traits were identified: sensitive-negative personality (65.2%), ordinary personality (26.6%), and open-positive personality (8.2%). Compared with nursing students with sensitive-negative personality, nursing students with ordinary personality and open-positive personality were associated with professional commitment, respectively [OR (95% CI): 7.01 (5.99-8.20), 21.09 (15.43-28.83)]. The p value for trend of personality and professional commitment was < 0.001. Metacognition was associated with professional commitment [OR (95% CI): 5.95 (5.20-6.81); p < 0.001]. Personality traits could modify the association between metacognition and professional commitment (pinteraction = 0.009). The mediating role of metacognition between Big Five personality and professional commitment has also been verified. Personality traits and metacognition of nursing students need to be paid attention to, and interventions based on metacognition may help nursing students with different personality traits to improve their professional commitment level.

Latent personality profiles of analog astronauts: An unsupervised clustering method analysis

The selection of astronauts for space missions is an important process that involves the assessment of multiple factors, including personality traits. Previous studies have corroborated that these traits exert a significant influence on the performance and adaptation of the crew during the execution of space missions. In this study, International Personality Item Pool - NEO – 120 (IPIP-120) was used to assess the personality of participants in a sample of 43 analog astronauts who took part in 9 different analog missions between 2022 and 2023. The objective was to identify specific personality profiles among the analog astronauts using the unsupervised k-means clustering method. The centroids of each cluster were analyzed to describe distinctive personality profiles. The results revealed the existence of two distinct personality clusters among the analog astronauts. The first cluster showed a greater propensity toward adventure, intellect, goal striving, extroversion, and cooperation. In contrast, the second cluster exhibited lower scores on these traits. The identification of these two differentiated personality profiles reinforces the importance of personality assessment as a valuable tool in the astronaut selection process. Furthermore, the application of the k-means method demonstrates its utility as an effective technique for identifying underlying patterns in complex datasets. These findings may inform future astronaut selection strategies, contributing to the formation of more effective and cohesive teams for space missions.

Research on Enhancing the Affinity of Ideological and Political Theory Courses in Private Universities in the New Era

In the new era, the ideological and political theory courses in private colleges and universities have the problem of insufficient affinity. College students in the new era have distinct personalities, psychology, and value orientations, but some college students feel distant from ideological and political theory courses. They do not pay attention to, understand, or even resist "big concepts" and "big propositions" such as the path, theory, system, and culture of socialism with Chinese characteristics, as well as the lofty ideals and beliefs. Therefore, effective countermeasures must be formed to create a warm ideological and political classroom from the aspects of teaching content, teaching methods, teaching practice, and teacher team building, so as to increase the closeness of ideological and political theory courses among college students. Only in this way can the spirit of patriotism take root in the hearts of students and give play to the positive influence of ideological and political theory courses on the values of young college students.

Digital political communication through a gender lens: discourses, themes, and inclusive language. A case study of two gender-balanced elections in Andalusia: 2018 and 2022

Electoral campaigns are particularly significant moments for identifying the available political options. Social media campaigns have become universal, and every candidate seeks to showcase their proposals and distinct political personality. The main goal of this article is to examine electoral political communication on social media platforms through a gender perspective. We analyze the messages posted on X (formerly Twitter) by candidates during the last two election campaigns in Andalusia. With a total sample of 2,196 posts, we applied quantitative content analysis and binary logistic regression, in addition to qualitative discourse análisis to a subset of the sample. We aim to identify how, where, when and by whom issues pertaining to women as a collective, feminism, gender, or the use of egalitarian language are introduced into two campaigns characterized by gender-balanced representation of candidates. Our findings indicate a limited use of inclusive language and infrequent foregrounding of women in discourse. Nonetheless, gender is a significant explanatory factor for a more inclusive communication style toward women, alongside an explicit emphasis on addressing policies affecting women.

The impacts of microplastics on zebrafish behavior depend on initial personality state

Microplastic pollution is associated with inflammation, gut dysbiosis and behavioral changes in fish. Fish have distinct personality traits but the role of personality in behavioral toxicology is rarely considered. We classified zebrafish on four behavioral axes: boldness, anxiety, sociability and exploration tendency then exposed them to low- or high- concentrations of two types of polyethylene microplastics (low- and high-density) for 28 days. Behaviors, antioxidant enzymes (catalase and superoxide dismutase), and gut microbiome were then measured. There were direct effects of microplastics on boldness, anxiety and sociability. However, fish retained their initial behavioral tendencies. Exposure to all microplastic treatments reduced average swimming speed and decreased the time spent motionless. Microplastic exposure did not affect antioxidant enzymes but did cause significant changes in the composition of the gut microbiome. This study demonstrates that environmentally realistic concentrations of microplastics can alter fish behavior, but much of the variance in response can be explained by personality.

Research on the History of Hou Hsiao-hsien’s Film Creation

As a leading figure in Taiwan’s “new film movement”, Hou Hsiao-hsien perfectly integrated the Western author’s film art tradition since the Italian neorealist film with the aesthetic purview of traditional Chinese culture and created the Chinese author’s film style. Hou Hsiao-hsien’s film works are very rational and connotation, with a strong documentary style and a sense of social distress, full of local flavor, and containing concern for Taiwan society. The film works have distinct personality and unique style, creating “Hou’s” artistic style through the lens language. This article will analyze Hou Hsiao-hsien’s film creation history from two aspects: the theme change and film style characteristics.

Personality matters – The interplay between consistent individual differences and mouse welfare in female C57BL6/J mice

To ensure good welfare of animals in human hands, it is essential to modify housing conditions according to the animals’ needs. Traditionally, the effects of such modifications are studied by means of group-level comparisons, thereby widely neglecting consistent inter-individual differences (i.e., so-called ‘animal personalities’). However, as animals with distinct personality types might differ in their environmental needs and hence react differently to the same environment, such systematic inter-individual differences might have important welfare consequences. This becomes particularly apparent under laboratory conditions, where animals are typically housed under highly standardized and barren environments. Against this background, we here aim to investigate personality-dependent welfare consequences in response to different housing conditions in laboratory mice. Female C57BL/6J mice were characterized for their personality type in exploration behavior and the most and the least explorative individuals were set up in either simple or in highly complex housing conditions that included constantly changing environmental enrichment items. We monitored individual welfare by studying behavioral, physiological, and immunological outcome measures. Besides personality-dependent differences in immune parameters and overall improved welfare under complex housing conditions, we indeed found hints that individual mice were differently affected in their welfare depending on the specific combination of personality type and housing condition. Specifically, highly explorative mice appeared to be more adversely affected by simple housing, but also profited more from complex housing compared to low explorative mice. These findings indicate that welfare promoting adjustments do not necessarily benefit all individuals equally and therefore, call for a shift of perspectives in the evaluation of animal welfare.

Enhancing MBTI Personality Prediction from Text Data with Advance Word Embedding Technique.

Understanding human personality traits is crucial for various domains, including psychology, education, and human resources. The Myers-Briggs Type Indicator (MBTI) is a widely recognized psychological assessment tool, categorizing individuals into one of sixteen distinct personality types. The existing methodologies, which primarily relied on Word2Vec embeddings and traditional machine learning models, showed promise but left room for improvement. To address this problem, this research focused on enhancing Myers-Briggs Type Indicator (MBTI) personality prediction from text data through advanced word-embedding techniques, specifically GloVe and BERT. The research investigates the effectiveness of various Machine Learning Classifiers, including Random Forest, XGBoost, LinearSVC, SGD, Logistic Regression, and CatBoost, in predicting MBTI personality types. Additionally, the impact of preprocessing techniques such as text cleaning, tokenization, TF-IDF vectorization, GloVe, and BERT embeddings on classification performance is examined. Furthermore, the research explores strategies for addressing class imbalance through upsampling techniques. Results indicate high accuracy and performance across multiple classifiers, with XGBoost achieving the highest accuracy of 97.33%. The analysis of MBTI dimensions reveals nuanced insights into the classifiers' ability to capture specific personality traits.

Experiences of compassion fatigue among Generation Z nurses in the emergency department: a qualitative study in Shanghai, China

BackgroundDue to the unique working environment and nature of work in emergency departments, nurses are prone to experiencing compassion fatigue (CF), leading to job burnout and attrition. As more Generation Z (Gen Z) nurses enter the emergency department with distinct personality traits compared to previous generations, studying their experiences with CF will inform future management strategies.MethodsThe qualitative phenomenological research method was utilised to investigate CF among Gen Z emergency nurses at a hospital in Shanghai, China. Data were collected through face-to-face semi-structured interviews and analyzed using Colaizzi’s seven-step phenomenological analysis method. Study participants were purposively selected.ResultsThree main themes and nine sub-themes emerged from the study: secondary traumatic stress, including physiological symptoms, psychological symptoms, and behavioral changes; cumulative effects, including impaired empathy, interference with family life, and post-traumatic growth (PTG); coping strategies, including cognitive reconstruction, seeking support, and facilitating action.ConclusionsThe aim of this study is to investigate the experience of CF among Gen Z emergency nurses, providing managers with a reference for future management strategies. The significance of multi-dimensional support for Gen Z emergency nurses is underscored by our findings. Additionally, interventions that enhance resilience and competency can facilitate their psychological transformation after experiencing CF and promote accelerated personal growth.

Effects of Personality and Behavioral Syndromes on Competition for Social Hierarchical Status in Anemonefish Amphiprion clarkii.

In this study, the behavioral ethogram of Amphiprion clarkii during the growth phase prior to sexual differentiation was summarized based on behavioral observations in three social environments. These behaviors can be classified into four categories: in addition to normal behaviors, the other three categories of behaviors-threatening, agonistic, and appeasing behaviors-represent different intentions in interactions with other individuals. Subsequently, the personalities of each individual were assessed by testing their reactions to intruders. These individuals mainly exhibited two distinct personality types: bold-aggressive and shy-submissive. In pairing experiments, the interactive behaviors of the anemonefish were observed in pairing combinations of different body sizes and personalities. The impact of personality on the establishment of a stable social hierarchy was confirmed by significant differences in the success rates of different pairing combinations, with the frequency of appeasing behaviors being the main factor influencing the success rate. Our results suggested that in natural waters, when juvenile individuals migrate among host anemones, shy-submissive individuals are more likely to be accepted due to their appeasing behaviors towards larger individuals, thus avoiding the risk of being attacked and bitten, and benefiting the survival of the individual. Conversely, bold-aggressive individuals are more likely to be driven away to another host anemone due to their unwillingness to settle for a lower-ranked status, thereby contributing to population dispersal and increasing opportunities for gene exchange between populations.

La Narrativa Española de Posguerra

With the Spanish Civil War (1936-1939), a new era began in Spanish literature. New promotions undertook the hard and difficult task of rebuilding the cultural life of the country even if they had to face different kinds of obstacles. The new poetic or novel productions were, without a doubt, the work of another generation. However, the literature of the first post-war years cannot be reduced to the production of those who joined it after 1939, given the invaluable contribution of highly distinguished personalities belonging to previous generations. If during the first post-war years, poetry had reached a certain development, the novel, already little cultivated in the preceding stage, remained stagnant in Spain until approximately 1945, at which time, for a series of reasons, among which we could mention the establishment of several literary awards, it began to replace translations of foreign authors. The political, economic, social and ideological consequences, in addition to the difficulties imposed by censorship, will influence the literary work of the moment and will, undoubtedly, constrain the creation of the novel

Becoming visible

While in England the memory of Thomas More had been erased from public life after his execution (6 June 1535), English Catholics exiled in the Spanish Netherlands preserved his figure and legacy. Furthermore, the inclusion of More’s engraving in 16th-century portrait books of distinguished personalities–the so-called viri illustres genre–, contributed to the promotion of the famous English humanist in continental Europe. Soon, More’s integrity and wisdom were extolled not only in works printed in Catholic countries but also in other territories that no longer accepted Rome’s authority. This paper analyses the depiction (both image and text) of the English humanist in all these works. The visual and textual rhetoric of these engravings shows their mutual dependence.

Alcohol sipping patterns, personality, and psychopathology inChildren: Moderating effects of dorsal anterior cingulate cortex (dACC) activation.

Alcohol, the most consumed drug in the United States, is associated with various psychological disorders and abnormal personality traits. Despite extensive research on adolescent alcohol consumption, the impact of early alcohol sipping patterns on changes in personality and mental health over time remains unclear. There is also limited information on the latent trajectory of early alcohol sipping, beginning as young as 9-10 years old. The dorsal anterior cingulate cortex (dACC) is crucial for cognitive control and response inhibition. However, the role of the dACC remains unclear in the relationship between early alcohol sipping and mental health outcomes and personality traits over time. Utilizing the large data from the Adolescent Brain Cognitive Development study (N = 11,686, 52% males, 52% white, mean [SD] age 119 [7.5] months, 9807 unique families, 22 sites), we aim to comprehensively examine the longitudinal impact of early alcohol sipping patterns on psychopathological measures and personality traits in adolescents, filling crucial gaps in the literature. We identified three latent alcohol sipping groups, each demonstrating distinct personality traits and depression score trajectories. Bilateral dACC activation during the stop-signal task moderated the effect of early alcohol sipping on personality and depression over time. Additionally, bidirectional effects were observed between alcohol sipping and personality traits. This study provides insights into the impact of early alcohol consumption on adolescent development. The key finding of our analysis is that poor response inhibition at baseline, along with increased alcohol sipping behaviors may accelerate the changes in personality traits and depression scores over time as individuals transition from childhood into adolescence.

Exploring CHAPS as a Potential Measurement for Auditory Processing and Cognitive Ability in Children with Hearing Loss.

The primary goal was to investigate the suitability of CHAPS for assessing cognitive abilities and auditory processing in people with hearing loss (HL), specifically in the domains of auditory processing, verbal working memory, and auditory attention. The study comprised 44 individuals between the ages of seven and 14, 22 with HL (N = 11 males) and 22 with normal hearing (N = 10 males). Individuals' auditory attention, working memory, and auditory processing skills were assessed in the study, and self-report questionnaires were used. The evaluation utilized the Sustained Auditory Attention Capacity Test (SAACT), Working Memory Scale (WMS), Filtered Words Test, Auditory Figured Ground Test (AFGT), and the Children's Auditory Performance Scale (CHAPS). Analyses were conducted, including group comparisons, correlation examinations, and receiver operating characteristic evaluations. There were significant differences in CHAPS total, attention, noise, quiet, and multiple inputs between groups. No significant differences were seen in CHAPS_ideal and CHAPS_auditory memory across groups. The study of SAACT and its subscores, WMS and its subscores, FWT, and AFGT revealed a significant difference between groups, caused by the poor performance of persons in the HL group compared to those in the NH group. The SAACT and its subscores correlated significantly with CHAPS_attention. The AUC calculation showed that The SAACT and CHAPS_attention distinguished persons with or without HL (p &lt; 0.05). WMS_STM and WMS_total correlated with CHAPS auditory memory subscale; however, WMS_VWM did not. AUC values for WMS and its subscores showed significant discrimination in identifying children with or without HL (p &lt; 0.05), whereas CHAPS_auditory memory did not (AUC = 0.665; p = 0.060). FWT and AFGT had a significant relationship with CHAPS_noise and CHAPS_multiple inputs subscales. The CHAPS_quiet and CHAPS_ideal subtests only correlated with AFGT. CHAPS_quite and CHAPS_ideal did not exhibit significant discriminative values (p &lt; 0.05) for identifying children with or without HL, while CHAPS_noise, CHAPS_multiple inputs, FWT, and AFGT did. The CHAPS_attention subscale could be a trustworthy instrument for assessing auditory attention in children with HL. However, the CHAPS_auditory memory subscale may not be suitable for testing working memory. While performance-based auditory processing tests showed improved discrimination, the CHAPS_noise and CHAPS_multiple inputs subtests can still assess hearing-impaired auditory processing. The CHAPS_quiet and CHAPS_ideal subtests may not evaluate auditory processing.

The structure and evolution of social psychology: a co-citation network analysis

ABSTRACT The present study examined the thematic composition and temporal evolution of social psychology through a co-citation network analysis of 80,350 articles published from 1970 through 2022. Six primary thematic clusters were identified: a broad “Classic Social Psychology” cluster most prominent in the 1970s and 1980s; “Traits & Affect” and “Social Cognition” clusters most influential in the 1990s; and “The Self,” “Intergroup Relations,” and “Big Five” clusters emerging after 2000. A small seventh cluster dedicated to COVID-19 and conspiracy theories emerged around 2021. These trends fit a narrative of generational shifts within distinct social and personality psychology traditions.

The death of the embodied philosopher and the life of the mind: On the literary and poetic features of Plato's Phaedo

AbstractSocrates is a man of faith whose love and pursuit of the truth is grounded in religious conviction. Faith, whatever else it may be, involves guiding one's life in terms of a transcendent dimension, recognizing a reality lying behind any particular experience. In Plato's Phaedo, a literary and philosophical masterpiece, we enter the narrative of Socrates' trial and execution on the day of his death, examining arguments for the immortality of the psyche. The dialogue combines logical argument and mythological speculation, and presents Socrates simultaneously as an abstract theorist and an unforgettably singular person. Distinct persons, such as Socrates, have an interest in continuing to exist as the individuals that they are. When we cease to exist, we lose the opportunity to engage in any activity that is worth doing, such as—emphatically, for some of us—doing philosophy. What Socrates is presented as having discovered in the Phaedo—with the ostensibly absent Plato lurking behind every line in this literary gem of a text—is a way of transforming oneself with an eye on immortality. That Socrates dies utterly without fear is the supreme vindication of the philosophical life.

A STUDY ON THE FACTORS INFLUENCING THE TURNOVER BEHAVIOR OF NEW GENERATION EMPLOYEES IN INSURANCE COMPANIES

Along with the rapid development of the insurance industry, the requirements for insurance practitioners are also increasing. From traditional insurance businesses to digital businesses, employees are required to maintain a high level of learning and work abilities in order to face the complex and ever-changing market environment. The advantages of the new generation of employees are their strong work ability and high learning ability, but the disadvantages are that they have distinct personalities and do not attach enough importance to the authority of their leaders. They like to act according to their own style when doing things. Using the new generation of employees properly can benefit the organization, but improper use can cause harm. With the increasing proportion of new-generation employees in the organization, how to effectively manage them, reduce their turnover rate, and ensure the stable development of the talent team is an issue that organizational management should pay attention to. Empirical analysis shows that three influencing factors, namely organizational fairness, promotion channels based on the term target responsibility system, and a highly flexible salary structure, can reduce the probability of turnover behavior among the new generation of employees in insurance companies. The highly flexible salary structure has the greatest impact on the turnover behavior of new generation employees in insurance companies, proving that addressing the material needs of new generation employees can stabilize the talent pool of new generation employees.
