Abstract [en]

The field of gender studies has faced criticism for poor scholarship and methodology, both from within and outside academia. Here, we compare indicators of scientific quality across three samples of peer-reviewed journal articles with more, less and no gender perspective, on the assumption that gender studies tend to apply a gender perspective. The statements in the articles were content-analysed with respect to subject matter, their level of support in surrounding text, and other indicators of scientific quality. The higher the level of gender perspective, the lower was the scientific quality for seven out of nine indicators. Support was higher for the no gender perspective group, but did not differ across the two higher levels. We suggest that the impact of the field can be increased by implementing established research methods employed in other disciplines, especially in terms of bringing about desired social and societal change.

Abstract [en]

One of the techniques used to induce trance state in shamanic ceremonies is monotonous drumming. According to previous EEG research, certain patterns of drumming cause an increase in power of alpha and theta frequencies of the listener. Present study aimed to determine, if suggestion to experience trance state could increase the relative alpha and theta amplitude and the intensity of experienced state. A group of twenty-four subjects participated in the study. Suggestion to experience trance state decreased alpha frequency power during the drumming condition. No other significant effects of suggestion or drumming were found.

Abstract [en]

Frost and Harpending, Evolutionary Psychology, 13 (2015), have argued that the increasing use of capital punishment across the Middle Ages in Europe altered the genotype, helping to create a less violent and generally more law-abiding population. Developing this insight, we hypothesise that the same system of violent punishments would also have helped to genotypically create a more religious society by indirectly selecting for religiousness, through the execution of men who had not yet sired any offspring. We estimate the selection differential for religiousness based on genetic correlation data for conceivably related traits, and compare that to the actual increase in religiosity across the Middle Ages. We further explore other mechanisms by which religiousness was being selected for in Medieval England, and conclude that executions most likely contributed substantially to the increase in religiosity, but that other selection pressures also played a role.

Abstract [en]

Music is a human universal, which suggests a biological adaptation. Several evolutionary explanations have been proposed, covering the entire spectrum of natural, sexual, and group selection. Here we consider the hypothesis that musical behaviour constitutes a reliable or even costly signal of fitness, and thus may have evolved as a human trait through sexual selection. We experimentally tested how musical performance quality (MPQ), in improvisations on the drums, saxophone, and violin, affects mate values and mate preferences perceived by a prospective partner. Swedish student participants (27 of each sex) saw a face of a person of the opposite sex and heard a piece of improvised music being played. The music occurred in three levels of MPQ and the faces in three levels of facial attractiveness (FA). For each parametric combination of MPG and FA, the participants rated four mate value scales (intelligence, health, social status, and parenting skill) and four mate preference scales (date, intercourse, and short- and long term relationship). Consistent with sexual selection theory, mate value ratings were generally increased by MPQ for raters of both sexes. Consistent with more specific hypotheses that follow from combining sexual selection and parental investment theory, women’s but not men’s preference for a long-term, but not short-term, relationship was significantly increased by MPQ, MPQ generally affected women’s ratings more than men’s, FA generally affected men’s ratings more than women’s, and women’s ratings of intelligence were even more influenced by MPQ than by FA.

Abstract [en]

Previous research indicates that the typical increase in IQ during childhood is greater in European countries than in Arab countries. A systematic literature review of age-dependent IQ in Arab countries is conducted, yielding relevant studies for 12 countries that fulfil the inclusion criteria. In almost all of these studies, Arab children exhibit an age-dependent IQ decline relative to Caucasian children, from 5 to about 12 years of age in particular. We term this phenomenon the Simber Effect. We propose two non-exclusive explanations. (1) The Flynn Effect is less intense in Arab countries because of localised differences, including poorer education quality and greater religiosity. (2) Those from Arab countries follow a faster Life History Strategy than Europeans, for environmental and possibly genetic reasons. Either way, the Simber Effect may amount to a Wilson Effect, meaning that the impact of genetic IQ increases with age.

Abstract [en]

Patterns of adoption behaviour are starkly asymmetric across populations. To better understand this phenomenon we conducted a systematic review of transracial adoption and adoption in general. We found six quantitative studies from the USA (with representative samples comprising a total of 117,000 participants) which had examined sex, race, and SES in relation to differences in behaviours and attitudes regarding both transracial adoption and adoption in general. A secondary analysis of these data found that transracial adopting is predicted by being female, white (as opposed to black), and of higher SES. These data are consistent with group differences in Life History Strategy – the Differential K model – regarding males and females, SES differences, and white and black people, but not with the fact that both transracial adoption and adoption rates in general seem to be lower in Northeast Asian countries. The influence of cultural factors upon these patterns may be addressed by future studies.

Abstract [en]

Background: General cognitive ability (CA) is positively associated with later physical and mental health, health literacy, and longevity. We investigated whether CA estimated approximately 30 years earlier in young adulthood predicted lifestyle-related risk factors and two-year survival in first myocardial infarction (MI) male patients.

Methods: Young adulthood CA estimated through psychometric testing at age 18–20 years was obtained from the mandatory military conscript registry (INSARK) and linked to national quality registry SWEDEHEART/RIKS-HIA data on smoking, diabetes, hypertension, obesity (BMI > 30 kg/m2) in 60 years or younger Swedish males with first MI. Patients were followed up in the Cause of Death registry. The 5659 complete cases (deceased = 106, still alive = 5553) were descriptively compared. Crude and adjusted associations were modelled with logistic regression.

Results: After multivariable adjustment, one SD increase in CA was associated with a decreased odds ratio of being a current smoker (0.63 [0.59, 0.67], P < 0.001), previous smoker (0.79 [0.73, 0.84], P < 0.001), having diabetes (0.82 [0.74, 0.90], P < 0.001), being obese (0.90 [0.84, 0.95], P < 0.001) at hospital admission, and an increased odds ratio of two-year survival (1.26 [1.02, 1.54], P < 0.001). CA was not associated with hypertension at hospital admission (1.03 [0.97, 1.10], P = 0.283).

Conclusions: This study found substantial inverse associations between young adulthood CA, and middle-age lifestyle risk factors smoking, diabetes, and obesity, and two-year survival in first MI male patients. CA assessment might benefit risk stratification and possibly aid further tailoring of secondary preventive strategy.

Abstract [en]

The aims of the study were (1) to investigate the effects of participation in low impact body conditioning classes on physical fitness in sedentary women at different ages and (2) to examine the correspondence between physical self-concept and participation in, and fitness change after, the participation. Ninety-two sedentary women (mean age 44.2 years) participated in 11-weeks of bi-weekly classes that included cardiovascular, strength, core, endurance and mobility exercises, all performed in synchrony with music. Cardiorespiratory fitness, maximal lifting strength, mobility and balance tests were performed pre- and post the exercise period and the short-form Physical Self-Description Questionnaire (PSDQ-S) was completed. Zero-order Spearman correlation analyses showed that women who rated the PSDQ-S dimension Sport competence higher participated in a larger number of sessions (rs=0.24, p=0.040). At post-tests, all participants had increased their balance, the participants aged 20-34 years had increased their lifting strength, and the participants aged 35-65 years had increased their cardiorespiratory fitness and mobility. Most PSDQ-S dimensions did not affect performance change, but the perception of being physically active was related to increased cardiovascular fitness. We conclude that women with a sedentary lifestyle who wish to increase their physical capacity benefit from music exercise and that inquiries about perceived sport competence and physical activity can improve recommendations made by strength and conditioning professionals.

Abstract [en]

The nature of the relationship between timing and cognition remains poorly understood. Cognitive control is known to be involved in discrete timing tasks involving durations above 1 s, but has not yet been demonstrated for repetitive motor timing below 1 s. We examined the latter in two continuation tapping experiments, by varying the cognitive load in a concurrent task. In Experiment 1, participants repeated a fixed three finger sequence (low executive load) or a pseudorandom sequence (high load) with either 524-, 733-, 1024- or 1431-ms inter-onset intervals (IOIs). High load increased timing variability for 524 and 733-ms IOIs but not for the longer IOIs. Experiment 2 attempted to replicate this finding for a concurrent memory task. Participants retained three letters (low working memory load) or seven letters (high load) while producing intervals (524- and 733-ms IOIs) with a drum stick. High load increased timing variability for both IOIs. Taken together, the experiments demonstrate that cognitive control processes influence sub-second repetitive motor timing.
