A Worldwide Test of the Predictive Validity of Ideal Partner Preference-Matching
Journal of Personality and Social Psychology, 2024
Abstract: Ideal partner preferences (i.e., ratings of the desirability of attributes like attractiveness or intelligence)are the source of numerous foundational findings in the interdisciplinary literature on human mating. Recently, research on the predictive validity of ideal partner preference-matching (i.e., do people positively evaluate partners who match versus mismatch their ideals?) has become mired in several problems. First, articles exhibit discrepant analytic and reporting practices. Second, different findings emerge across laboratories worldwide, perhaps because they sample different relationship contexts and/or populations. This registered report—partnered with the Psychological Science Accelerator—uses a highly powered design (N=10,358) across 43 countries and 22 languages to estimate preference-matching effect sizes. The most rigorous tests revealed significant preference-matching effects in the whole sample and for partnered and single participants separately. The “corrected pattern metric” that collapses across 35 traits revealed a zero-order effect of β=.19and an effect of β=.11 when included alongside a normative preference-matching metric. Specific traits in the “level metric” (interaction) tests revealed very small(averageβ=.04) effects. Effect sizes were similar for partnered participants who reported ideals before entering a relationship, and there was no consistent evidence that individual differences moderated any effects. Comparisons between stated and revealed preferences shed light on gender differences and similarities: For attractiveness, men’s and (especially) women’s stated preferences underestimated revealed preferences (i.e., they thought attractiveness was less important than it actually was). For earning potential, men’s stated preferences underestimated—and women’s stated preferences overestimated—revealed preferences. Implications for the literature on human mating are discussed.
Motivation States for Physical Activity and Sedentary Behavior: Desire, Urge, Wanting, and Craving
Frontiers in Psychology, 2020
Abstract: To better explain daily fluctuations in physical activity and sedentary behavior, investigations of motivation are turning from social cognitive frameworks to those centered on affect, emotion and automaticity, such as the Affect and Health Behavior Framework (AHBF), Integrated Framework and Affective-Reflective Theory (ART). This shift has necessitated: (a) re-examination of older theories and their constructs, such as drives, needs and tensions and (b) an inspection of competing theories from other fields that also attempt to explain dynamic changes in health behaviors. The Dynamical Model of Desire, Elaborated Intrusion Theory and others commonly share with AHBF the idea that human behavior is driven strongly by desires and/or the similar concepts of wants, urges, and cravings. These affectively-charged motivation states (ACMS) change quickly and may better explain physical activity behavior from one moment to the next. Desires for movement predominantly derive from negative but also positive reinforcement. Data from clinical populations with movement dysfunction or psychiatric disorders provides further evidence of these drivers of movement. Those with Restless Legs Syndrome, akathisia, tic disorders and exercise dependence all report strong urges to move and relief when it is accomplished. Motor control research has identified centers of the brain responsible for wants and urges for muscular movement. Models elaborated herein differentiate between wants, desires, urges and cravings. The WANT model (Wants and Aversions for Neuromuscular Tasks) conceptualizes desires for movement and rest as varying by magnitude, approach or avoidance-orientation (wants versus aversions) and as occupying independent dimensions instead of opposite ends of the same axis. For instance, one hypothetically might be in a state of both high desire for movement and rest simultaneously. Variations in motivation states to move and rest may also be associated with various stress states, like freezing or fight and flight. The first validated instrument to measure feelings of desire/want for movement and rest, the CRAVE Scale (Cravings for Rest and Volitional Energy Expenditure) is already shedding light on the nature of these states. With these advances in theory, conceptual modeling and instrumentation, future investigations may explore the effects of desires and urges for movement and sedentary behavior in earnest.

Sexual Dimorphism and the Origins of Human Spinal Health
Endocrine Reviews, 2018
Abstract: Recent observations indicate that the cross-sectional area (CSA) of vertebral bodies is on average 10% smaller in healthy newborn girls than in newborn boys, a striking difference that increases during infancy and puberty and is greatest by the time of sexual and skeletal maturity. The smaller CSA of female vertebrae is associated with greater spinal flexibility and could represent the human adaptation to fetal load in bipedal posture. Unfortunately, it also imparts a mechanical disadvantage that increases stress within the vertebrae for all physical activities. This review summarizes the potential endocrine, genetic, and environmental determinants of vertebral cross-sectional growth and current knowledge of the association between the small female vertebrae and greater risk for a broad array of spinal conditions across the lifespan.
Fetal testosterone predicts sexually differentiated childhood behavior in girls and in boys
Psychological Science, 2009
Abstract: Mammals, including humans, show sex differences in juvenile play behavior. In rodents and nonhuman primates, these behavioral sex differences result, in part, from sex differences in androgens during early development. Girls exposed to high levels of androgen prenatally, because of the genetic disorder congenital adrenal hyperplasia, show increased male-typical play, suggesting similar hormonal influences on human development, at least in females. Here, we report that fetal testosterone measured from amniotic fluid relates positively to male-typical scores on a standardized questionnaire measure of sex-typical play in both boys and girls. These results show, for the first time, a link between fetal testosterone and the development of sex-typical play in children from the general population, and are the first data linking high levels of prenatal testosterone to increased male-typical play behavior in boys.
Establishing common course objectives for undergraduate exercise physiology
Advances in Physiology Education, 2015
Abstract: Undergraduate exercise physiology is a ubiquitous course in undergraduate kinesiology/exercise science programs with a broad scope and depth of topics. It is valuable to explore what is taught within this course. The purpose of the present study was to facilitate an understanding of what instructors teach in undergraduate exercise physiology, how it compares with various guidelines, and to continue the conversation regarding what should be taught. A survey was created using course outcomes from the American Society of Exercise Physiologists, National Association for Sport and Physical Education, Ivy's 2007 Quest article, the National Athletic Training Association, the National Council for Accreditation of Teacher Education, and 36 undergraduate exercise physiology course syllabi. The 134-item survey was disseminated to individuals who use exercise physiology: university faculty members, clinical exercise physiologists, researchers, and other practitioners on various exercise physiology lists; 2,009 surveys were sent, and 322 surveys were completed (16% rate of return). There was a high degree of agreement about a lot of important content in undergraduate exercise physiology. Instructors of exercise physiology should focus their curriculum on regulation and homeostasis (including adaptation, fatigue, and recovery), aerobic systems, bioenergetics, muscle physiology, and fitness principles. In addition, attention should be paid to performance and technical skills. In conclusion, it is up to exercise physiologists to ensure quality of knowledge and practice. Doing so will improve the uniformity and quality of practitioners within the various kinesiology/exercise science fields and increase the value of a Kinesiology/Exercise Science degree and set it apart from other healthcare providers and fitness professionals.

“Suck It up, Buttercup”: Status Silencing and the Maintenance of Toxic Masculinity in Academia
Radical Interactionism and Critiques of Contemporary Culture, 2021
Abstract: This autoethnography takes up the matter of toxic masculinity in university settings. We introduce the term “status silencing” as a way to make visible the normalization of toxic masculinity in everyday talk and interaction in university settings among and around colleagues. Status silencing is the process in which the status of a dominant individual becomes a context which renders the story of an individual with a subordinated status untellable or untold. Using strange accounting, we explore active and passive types of status silencing to show how talk and interactions involving toxic masculinity are both internalized and externalized expressions of power and dominance. We argue that while most scholars view toxic masculinity as blatant acts of violence (mass shootings, rape and sexual assault, etc.), it is also a normalized occurrence for feminized others and that toxic masculinity in academic settings is part of an ongoing institutional norm of silence.

I’m not suggesting all people with high testosterone are potential criminals. But when it’s combined with low intelligence or poor impulse control you can have problems. Also, it seems to be more related to violent crime rather than premeditated or financial crime.
It plays a role.
The article on the same-sex relationship and crime study seems to be overlooking a fairly obvious explanation. Lesbians are more prone to masculine behaviours than straight women are. Conversely, gay men are generally less aggressive than straight men. This might have something to do with testosterone. It’s reasonable to expect straight men to be most likely to commit crimes, straight women to be least likely, and gays and lesbians to be somewhere in between
