Varella MAC. Nocturnal selective pressures on the evolution of human musicality as a missing piece of the adaptationist puzzle. Front Psychol 2023; 14:1215481.

Abstract
Human musicality exhibits the necessary hallmarks for biological adaptations. Evolutionary explanations focus on recurrent adaptive problems that human musicality possibly solved in ancestral environments, such as mate selection and competition, social bonding/cohesion and social grooming, perceptual and motor skill development, conflict reduction, safe time-passing, transgenerational communication, mood regulation and synchronization, and credible signaling of coalition and territorial/predator defense. Although not mutually exclusive, these different hypotheses are still not conceptually integrated nor clearly derived from independent principles. I propose The Nocturnal Evolution of Human Musicality and Performativity Theory in which the night-time is the missing piece of the adaptationist puzzle of human musicality and performing arts. The expansion of nocturnal activities throughout human evolution, which is tied to tree-to-ground sleep transition and habitual use of fire, might help (i) explain the evolution of musicality from independent principles, (ii) explain various seemingly unrelated music features and functions, and (iii) integrate many ancestral adaptive values proposed. The expansion into the nocturnal niche posed recurrent ancestral adaptive challenges/opportunities: lack of luminosity, regrouping to cook before sleep, imminent dangerousness, low temperatures, peak tiredness, and concealment of identity. These crucial night-time features might have selected evening-oriented individuals who were prone to acoustic communication, more alert and imaginative, gregarious, risk-taking and novelty-seeking, prone to anxiety modulation, hedonistic, promiscuous, and disinhibited. Those night-time selected dispositions may have converged and enhanced protomusicality into human musicality by facilitating it to assume many survival- and reproduction-enhancing roles (social cohesion and coordination, signaling of coalitions, territorial defense, antipredatorial defense, knowledge transference, safe passage of time, children lullabies, and sexual selection) that are correspondent to the co-occurring night-time adaptive challenges/opportunities. The nocturnal dynamic may help explain musical features (sound, loudness, repetitiveness, call and response, song, elaboration/virtuosity, and duetting/chorusing). Across vertebrates, acoustic communication mostly occurs in nocturnal species. The eveningness chronotype is common among musicians and composers. Adolescents, who are the most evening-oriented humans, enjoy more music. Contemporary tribal nocturnal activities around the campfire involve eating, singing/dancing, storytelling, and rituals. I discuss the nocturnal integration of musicality's many roles and conclude that musicality is probably a multifunctional mental adaptation that evolved along with the night-time adaptive landscape.

Abstract
BACKGROUND Infertility is one of the most important challenges in the modern life that can damage the sexual satisfaction and marital intimacy of couples. The present study was aimed to investigate the effectiveness of reality therapy on sexual satisfaction and marital intimacy of infertile women. MATERIALS AND METHODS This quasi-experimental study was conducted with a pretest-posttest design and follow-up. The statistical population was infertile women who were referred to Imam Sajjad Shahriyar Hospital in 2019-2020. 15 infertile women selected by purposive sampling and underwent reality therapy (8 sessions of 90 min). Data were collected using index sexual satisfaction (ISS) and marital intimacy questionnaire. Data analysis was performed using SPSS-24 software, analysis of variance with repeated measures and post hoc Bonferroni test. RESULTS The results of analysis of variance showed that there was a significant difference between the scores of sexual satisfaction and marital intimacy in posttest and follow-up stages compared to pretest (P < 0.05). CONCLUSIONS Based on the results, reality therapy can be used as an effective intervention to improvement sexual satisfaction and marital intimacy of infertile women.

Abstract
Chapman’s Love Languages hypothesis claims that (1) people vary in the ways they prefer to receive and express affection and (2) romantic partners who communicate their feelings congruent with their partner’s preferences experience greater relationship quality. The author proposes five distinct preferences and tendencies for expressing love, including: Acts of Service, Physical Touch, Words of Affirmation, Quality Time and Gifts. In the present study partners (N = 100 heterosexual couples) completed measures assessing their preferences and behavioral tendencies for a) expressions of love and b) reception of signs of affection, for each of the five proposed “love languages”. Relationship satisfaction, sexual satisfaction and empathy were also assessed. The degree of the within-couple mismatch was calculated separately for each individual based on the discrepancies between the person’s felt (preferred) and their partner’s expressed love language. The joint mismatch indicator was a sum of discrepancies across the five love languages. Matching on love languages was associated with both relationship and sexual satisfaction. In particular, people who expressed their affection in the way their partners preferred to receive it, experienced greater satisfaction with their relationships and were more sexually satisfied compared to those who met their partner’s needs to lesser extent. Empathy was expected to be a critical factor for better understanding of and responding to the partner’s needs. Results provided some support for this hypothesis among male but not female participants.

Abstract
PURPOSE This study aimed to investigate the relationships between intravaginal ejaculatory latency time (IELT), severity of disease, and chronotype in lifelong premature ejaculation (PE). MATERIALS AND METHODS Evaluation was made of 114 males with PE and 103 healthy individuals, and comparisons were made of self-estimated IELT, Arabic Index of Premature Ejaculation (AIPE), Pittsburg Sleep Quality Index (PSQI), and Morningness-Eveningness Questionnaire (MEQ). RESULTS The frequency of morningness chronotype (78.1%) was significantly higher, and Morningness-Eveningness Questionnaire (MEQ) scores were negatively correlated with both IELT (r = -0.490, p < 0.001) and Arabic Index of Premature Ejaculation (AIPE) scores (r = -0.639, p < 0.001) in the PE group. MEQ scores significantly predicted IELT (t = -2.465, p = 0.015) and AIPE scores (t = -4.003, p = 0.000) in the PE group but not in the control group. CONCLUSION It can be asserted that morningness chronotype is more common, and ejaculatory latency time and PE severity are associated with chronotype in males with PE.

Abstract
BACKGROUND Bed sharing is common practice across the global population. However, the vast majority of research on bed sharing has focused solely on mother-infant bed sharing. METHODS Here, we provide a holistic review of research on bed sharing. Articles investigating the relationship between bed sharing and sleep were identified in 4 dyad categories: (1) parent and child, (2) couples, (3) siblings, and (4) pet owners and pets. Of interest was whether sleep-promoting factors such as psychological comfort were generalizable across bed-sharing dyads; alternatively, sleep-demoting factors such as movement or heat may be commonalities. RESULTS We found that, across dyad types, in general, subjective reports of sleep quality were better when bed sharing despite generally worse objective measures of sleep. CONCLUSIONS Understanding bed sharing is important to treating sleep disturbances, given the prevalence of shared beds. This scoping review points to critical gaps in our understanding of bed sharing that motivate future research.

Front Psychol 2021; 12:646711. [PMID: 33828510 PMCID: PMC8019933 DOI: 10.3389/fpsyg.2021.646711] [Citation(s) in RCA: 9] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/28/2020] [Accepted: 02/19/2021] [Indexed: 12/19/2022] Open
Abstract
Humans have been using fire for hundreds of millennia, creating an ancestral expansion toward the nocturnal niche. The new adaptive challenges faced at night were recurrent enough to amplify existing psychological variation in our species. Night-time is dangerous and mysterious, so it selects for individuals with higher tendencies for paranoia, risk-taking, and sociability (because of security in numbers). During night-time, individuals are generally tired and show decreased self-control and increased impulsive behaviors. The lower visibility during night-time favors the partial concealment of identity and opens more opportunities for disinhibition of self-interested behaviors. Indeed, individuals with an evening-oriented chronotype are more paranoid, risk-taking, extraverted, impulsive, promiscuous, and have higher antisocial personality traits. However, under some circumstances, such as respiratory pandemics, the psychobehavioral traits favored by the nocturnal niche might be counter-productive, increasing contagion rates of a disease that can evade the behavioral immune system because its disease cues are often nonexistent or mild. The eveningness epidemiological liability hypothesis presented here suggests that during the COVID-19 pandemic, the evening-oriented psychobehavioral profile can have collectively harmful consequences: there is a clash of core tendencies between the nocturnal chronotype and the recent viral transmission-mitigating safety guidelines and rules. The pandemic safety protocols disrupt much normal social activity, particularly at night when making new social contacts is desired. The SARS-CoV-2 virus is contagious even in presymptomatic and asymptomatic individuals, which enables it to mostly evade our evolved contagious disease avoidance mechanisms. A growing body of research has indirectly shown that individual traits interfering with social distancing and anti-contagion measures are related to those of the nocturnal chronotype. Indeed, some of the social contexts that have been identified as superspreading events occur at night, such as in restaurants, bars, and nightclubs. Furthermore, nocturnal environmental conditions favor the survival of the SARS-CoV-2 virus much longer than daytime conditions. We compare the eveningness epidemiological liability hypothesis with other factors related to non-compliance with pandemic safety protocols, namely sex, age, and life history. Although there is not yet a direct link between the nocturnal chronotype and non-compliance with pandemic safety protocols, security measures and future empirical research should take this crucial evolutionary mismatch and adaptive metaproblem into account, and focus on how to avoid nocturnal individuals becoming superspreaders, offering secure alternatives for nocturnal social activities.

The Parent's Chronotype and Child's Sleeping Quality in Association with Relationship Satisfaction. Clocks Sleep 2020; 2:375-389.

Abstract
The prospective Ulm-SPATZ study was investigated to assess the role of child sleeping quality between 4 to 6 years of age in affecting a partner's sleeping and relationship satisfaction within a couple. The study was conducted using a triadic approach in which the child was included in the Actor-Partner-Interdependence Model (APIM). Sleeping quality of the child was determined by using the German version of the children's sleep habits questionnaire, sleeping features of the parents were assessed by using the Munich chronotype questionnaire, and the partner relationship assessment was performed by employing the German version of the parenting stress index questionnaire. In 211 German triads, we observed that sleeping characteristics and partner relationship scores at different child ages are consistent for both men and women. Higher and statistically significant sleep duration, time spent in bed, the midpoint of sleep, time getting out of bed, and sleep onset in women compared to men during the working days were observed. The APIM analyses showed a significant direct effect of child sleep quality on the partner relationship satisfaction. In women, a mediated effect of child sleep quality acted through sleep duration and time spent in bed on the partner relationship satisfaction score during both free and working days. In men, low child sleep quality was found to be associated with increased sleep onset during both free and working days. Child sleep quality influences relationship satisfaction mostly in mothers, likely because of their higher involvement in childcare during working days. Distress in the couple could be counteracted by a major involvement of the fathers in child management.

Abstract
Morningness-eveningness (chronotype) indicates the preferred time of intellectual and physical activity. This cross-sectional study had two main aims. The first aim was to explore associations among chronotype, quality of life, and relationship quality. The second aim of this study was to examine whether the similarities or discrepancies in chronotype between male and female members of the couples were linked to relationship quality. Both members of 143 couples (mean age = 39.44; SD = 10.11y) living together for at least 6 months completed measures of chronotype, marital stress, relationship satisfaction, dyadic coping, satisfaction with life, health-related quality of life, and quality of sleep. Variable-oriented (correlational) and person-oriented (cluster-analytic) analyses were conducted. Variable-oriented analyses showed that morningness was linked to better mental health, and fewer insomnia problems, but less frequent (self-perceived) stress communication for both genders. The discrepancy between the couple's chronotype scores was positively related to the women's sexual and general life satisfaction and more frequent (self-perceived) supportive dyadic coping by the partner. Moreover, ANOVA results showed that Evening-type (E-type) women had the highest mean score on sexual life satisfaction. According to cluster-analytic investigation, couples consisting of two morning-type members had the least frequent stress communication. On the other hand, these couples had better sleeping quality with less insomnia symptoms than couples with two E-type members. In summary, the present findings demonstrate that morningness holds both advantages and disadvantages for both general aspects of life and also the quality of relationships.

Associations between Chronotype, Adherence to the Mediterranean Diet and Sexual Opinion among University Students. Nutrients 2020; 12:nu12061900.

Abstract
A person's chronotype determines different habits, among which are eating and physical activity. Furthermore, at the university stage, social and organisational factors have a direct effect on students' daily attitudes and habits. Adherence to the Mediterranean diet is linked to better sleep quality and less social jet lag, but association with chronotype or sexual opinion remains unclear. The aim of this study was to assess the associations between chronotype, adherence to the Mediterranean Diet, and sexual opinion. A multicentre observational study enrolled 457 students, from the University of Castilla-La Mancha and the University of Cordoba. Sociodemographic data and adherence to the Mediterranean diet, chronotype, physical activity, and sexual opinion were collected with validated questionnaires. The study period was from December 2017 to January 2018. Our results reported that students with an evening chronotype (E-type), with evening preferences, had a lower adherence to the Mediterranean diet and showed a higher tendency towards erotophilia. E-type students reported a significantly lower intake of fruits, vegetables, pulses, cereals, and olive oil, and higher breakfast skipping. Therefore, among the measures to promote healthy habits (obesity prevention, sexual education, socialisation, etc.), chronotype and an analysis of the impact of the schedules established by the universities must be considered.
