Father absence, attraction and development

Since Draper & Harpending (1982) proposed that father absence would be associated with a shift in reproductive strategy, a body of literature has accumulated supporting their claims. This thesis explores further aspects of father absence theory, utilising computergraphic facial processing. It opens with an overview of both father absence theory (Chapter 1) and the Evolutionary Psychology of attraction (Chapter 2). Part 1 Part 1 explores the meaning of masculinity in partner choice scenarios. Male facial masculinity co-varied with facial age but not apparent facial health both in tenns of women's preferences (Study 1) and women's direct perceptions (Study 2). This suggested that masculinity in male faces is not a cue to immunocompetence health status as other authors have suggested, In Study 3, while masculine faces were perceived as more dominant than feminised faces, they were otherwise considered poorer quality partners. It was suggested that masculinity was attractive because of a 'sexy son' mechanism (dominance increasing offspring reproductive success), which was traded off against the anti-social traits associated with masculinity. Part 2 Studies 4, 5 and 6 found that father absence or poor relationships with the parents generally reduced masculinity preference and age preference (although in Study 5, this effect was moderated by relationship status). This contradicted predictions made from traditional father absence literature (that father absence should be associated with a short term strategy and therefore masculinity preference). Sociological explanations were discounted as family background did not relate to the traits women said they desired in a partner (Study 7). Altogether these results raised questions about the attractiveness and self-esteem of father absent females. Part 3 therefore investigated the physical development of these females. Part 3 Study 8 found that marital difficulties between parents were associated with an increase in perceived facial masculinity in both male and female offspring's faces, a decrease in facial attractiveness and increased weight and waist-hip ratio in women. Study 9 found that levels of progesterone were inversely related to quality of parental relationship. The overarching conclusions of the thesis were that there appears to be an effect' of physical masculinisation which is associated with father absence. This masculinisation may be the predicator for previously observed father absence effects, and the results in Part 2. As such, attachment based explanations of father absence effects (such as Belsky et al, 1991) may be redundant

Impact arising from sustained public engagement: A measured increase in learning outcomes

This article details the impact arising from a sustained public engagement activity with sixth-form students (16 to 17 year olds) across two Further Education Colleges during 2012/13. Measuring the impact of public engagement is notoriously difficult. As such, the engagement programme closely followed the recommendations of the National Co-ordinating Centre for Public Engagement (NCCPE) and their guidance for assessing Research Excellence Framework 2014 (REF2014) impact arising from public engagement with research. The programme resulted in multiple impacts as defined by the REF2014 under “Impacts on society, culture and creativity”. Specifically: the beneficiaries’ interest in science was stimulated; the beneficiaries’ engagement in science was improved; their science-related education was enhanced; the outreach programme made the participants excited about the science topics covered; the beneficiaries’ awareness and understanding was improved by engaging them with the research; tentative evidence of an improvement in AS-level grades; indirect evidence of an improvement in student retention. These impacts were evidenced by the user feedback (i.e. sixth-form students) collected from 50 questionnaires (split 16 and 34 across the two Further Education Colleges), as well as testimonies from both the teachers and individual participants

Female facial appearance and health

The current study addressed whether rated femininity, attractiveness, and health in female faces are associated with numerous indices of self-reported health history (number of colds/stomach bugs/frequency of antibiotic use) in a sample of 105 females. It was predicted that all three rating variables would correlate negatively with bouts of illness (with the exception of rates of stomach infections), on the assumption that aspects of facial appearance signal mate quality. The results showed partial support for this prediction, in that there was a general trend for both facial femininity and attractiveness to correlate negatively with the reported number of colds in the preceding twelve months and with the frequency of antibiotic use in the last three years and the last twelve months. Rated facial femininity (as documented in September) was also associated with days of flu experienced in the period spanning the November-December months. However, rated health did not correlate with any of the health indices (albeit one marginal result with antibiotic use in the last twelve months). The results lend support to previous findings linking facial femininity to health and suggest that facial femininity may be linked to some aspects of disease resistance but not others

Is Female Attractiveness Related to Final Reproductive Success?

In order to test the assumption that female attractiveness relates to reproductive success, photographs of 47 rural Polish women taken in their youth were rated for attractiveness, and BMI at age 18 was recorded; these measures of attractiveness were then compared with their subsequent life histories. Facial attractiveness did not relate to number of children or grandchildren. It also did not relate to age of marriage or husband’s education. It did relate to number of marriages and husband’s height. BMI at age 18 did not relate significantly to any of the outcome variables. These results suggest that although more attractive women may have married higher quality (taller) husbands and may in ancestral population have achieved greater reproductive success this way, there is no evidence in a modern, European Catholic society for their having greater reproductive success

Callous-Unemotional Traits are Associated with Child-to-Parent Aggression

This study examined the relations between callous-unemotional traits and perpetration of aggression toward parents in two separate studies, while also considering motivation for aggression and parenting styles experienced among young people. Study 1 involved 60 parents of children aged between 11 and 17 years old. The online study found high callous-unemotional traits, as reported by parents, to be associated with aggression toward both parents. Both types of motivation (proactive and reactive, as reported by parents) were associated with aggression toward parents. Study 2 involved 42 youths from an alternative education sample (between 11 and 16 years old). Youths with higher self-reported callous-unemotional traits reported more aggression toward both parents. Both studies, which had different reporters and different samples, showed youths with higher callous-unemotional traits were more aggressive toward their parents. In discussing the results, we note the importance of including callous-unemotional traits in future research on parentdirected aggression and in studies on domestic violence more broadly

Validation of a Latin-American Spanish version of the Body Esteem Scale for Adolescents and Adults (BESAA-LA) in Colombian and Nicaraguan adults

Background: Body dissatisfaction (BD) is a growing concern in Latin America; reliable and culturally appropriate scales are necessary to support body image research in Spanish speaking Latin American countries. We sought to validate a Latin-American Spanish version of the Body Esteem Scale for Adolescents and Adults (BESAA; Mendelson et al. 2001). Methods: The BESAA was translated, culturally adapted, and validated in a sample of adults in Colombia (N = 525, 65% women, Mage 24.4, SD = 9.28). We assessed factor structure (using confirmatory factor analysis (CFA), exploratory factor analysis (EFA) and exploratory structural equation model (ESEM)), internal reliability (using Cronbach’s alpha and omega), validity (using the Body Appreciation Scale BAS and Sociocultural Attitudes Towards Appearance Questionnaire SATAQ), test–retest stability in a small subsample (N = 84, using Intraclass correlations ICC) and measurement invariance across gender. To evaluate the generalizability of the scale, we assessed reliability, validity, and factor structure in a second sample from rural Nicaragua (N = 102, 73% women, Mage 22.2, SD = 4.72), and assessed measurement invariance across Nicaraguan and Colombian participants. Results: The scale showed good internal reliability and validity in both samples, and there was evidence of adequate test–retest stability in the Colombian sample. EFA showed a three-factor structure with subscales we labelled ‘appearance-positive’, ‘appearance-negative’ and ‘weight’, that was confirmed using CFA and ESEM in the Colombian sample. Measurement invariance was confirmed across the Colombian and Nicaraguan samples, and across gender within the Colombian sample. Conclusion: The Latin-American Spanish version of the BESAA (BESAA-LA) appears to be a psychometrically sound measure with good reliability, validity and invariance across gender and countries. These results support the use of this scale to measure body satisfaction/dissatisfaction in Latin American adult populations

Narcissism and the strategic pursuit of short-term mating : universal links across 11 world regions of the International Sexuality Description Project-2.

Previous studies have documented links between sub-clinical narcissism and the active pursuit of short-term mating strategies (e.g., unrestricted sociosexuality, marital infidelity, mate poaching). Nearly all of these investigations have relied solely on samples from Western cultures. In the current study, responses from a cross-cultural survey of 30,470 people across 53 nations spanning 11 world regions (North America, Central/South America, Northern Europe, Western Europe, Eastern Europe, Southern Europe, Middle East, Africa, Oceania, Southeast Asia, and East Asia) were used to evaluate whether narcissism (as measured by the Narcissistic Personality Inventory; NPI) was universally associated with short-term mating. Results revealed narcissism scores (including two broad factors and seven traditional facets as measured by the NPI) were functionally equivalent across cultures, reliably associating with key sexual outcomes (e.g., more active pursuit of short-term mating, intimate partner violence, and sexual aggression) and sex-related personality traits (e.g., higher extraversion and openness to experience). Whereas some features of personality (e.g., subjective well-being) were universally associated with socially adaptive facets of Narcissism (e.g., self-sufficiency), most indicators of short-term mating (e.g., unrestricted sociosexuality and marital infidelity) were universally associated with the socially maladaptive facets of narcissism (e.g., exploitativeness). Discussion addresses limitations of these cross-culturally universal findings and presents suggestions for future research into revealing the precise psychological features of narcissism that facilitate the strategic pursuit of short-term mating

En este estudio se han usado respuestas de la encuesta transcultural de 30.470 personas de 53 naciones de 11 regiones mundiales (América del Norte, América del Sur/América Central, Europa del Norte, Europa del Oeste, Europa del Este, Europa del Sur, Oriente Próximo, África, Asia del Sur/Sudoeste de Asia, Asia del Este y Oceanía) para evaluar si el narcisismo (medido por el Inventario de Personalidad Narcisista; NPI) se asocia panuniversalmente con los indicadores del emparejamiento a corto plazo, tanto en la dirección, como en la intensidad. Los resultados sugieren que el narcisismo (incluidos muchos aspectos suyos medidos por el NPI) tiene las mismas asociaciones básicas con los rasgos de personalidad relacionados con el sexo (p. ej. extraversión alta) y con los resultados sexuales claves (p. ej. búsqueda más activa de las estrategias del emparejamiento a corto plazo) a través de las 11 mayores regiones mundiales del PDSI 2. La discusión se enfoca en las implicaciones y limitaciones del estudio actual
