“…Most recently, Butaric et al (2022b) indicated frontal sinus shape (as determined by outlines) established around 14-16yoa for females versus 18-20yoa in males. Thus, the results of the current study and previous studies follow well-established trends in skeletal maturity throughout the skeleton, with females tending to reach maturity (in this case frontal sinus stabilization) earlier than males (Bulygina et al 2006;Eveleth & Tanner 1990;Roche 1968;Nikitovic & Bogin 2014;Wells 2007). Despite these observable trends, Bonferroni adjusted p-values, however, did not find statistical sex-based differences in ages-ofstabilization for most traits.…”

Forensic studies on frontal sinus identification are often limited to adult samples or utilize static, simulated antemortem images, which overlook any potential temporal changes in sinus morphology. Further, studies on frontal sinus growth typically utilize lateral radiographs and/or are cross-sectional. The current study utilizes a longitudinal sample of frontal radiographs to determine the age at which forensically relevant frontal sinus traits stabilize during growth and development. The sample includes 1500 radiographs of 141 individuals (66F/75M) ranging from three to 56 years of age (yoa). For each individual, trait age-of-stabilization was recorded by identifying the year at which each coded trait became consistent across images.Our results demonstrate that frontal sinus traits stabilize on average 10–15yoa, with sinus presence being the first to stabilize and arcade counts the last. Females generally stabilized earlier (9–14yoa) versus males (10–15yoa). However, sex differences were generallynot statistically significant. Further, traits displayed a high degree of variation with wide standard deviations (~3 years). However, by 21yoa almost all individuals displayed stabilization in all traits, suggesting that little change should be expected with later-aged postmortem radiographs. Still, given the amount of variation, forensic practitioners should be cautious using frontal sinus identification methods in subadults, especially when years may have elapsed between images. When conducting a radiographic comparison that involves a subadult antemortem image, the results of this study may help the practitioner interpret whether the differences between antemortem and postmortem radiographs can be explained by age and time elapsed between radiographs.

“…Underlying this argument is evidence that gender differences in the timing and composition of hormonal cascades during early gestation create gender differences in rates of development, such that male development is delayed relative to female development (Breedlove, 1994;Levy & Heller, 1992;Reinisch & Sanders, 1992). This delay is most visible in skeletal maturity and other markers of physical growth (Breedlove, 1994;Flory, 1935;Roche, 1968), but there is general consensus that brain development in males is also delayed, resulting in infant gender differences in left hemisphere maturity and in the lateralization and organization of function within the brain (see e.g., Friederici et al, 2008;Hanlon, Thatcher, & Cline, 1999;Shucard, Shucard, & Thomas, 1987). 1 These, in turn, produce gender differences in perception and attention that have been well documented (see e.g., Notman & Nadelson, 1991;Reinisch & Sanders, 1992).…”

The study examined parent, child, and dyadic gender effects in parent reports of words and MLUs. Mothers and fathers from 113 families completed the MacArthur Communicative Development Inventory: Toddlers when the toddlers were 1;7; half completed a follow-up at 2;0. Child gender differences in words and MLUs increased over time and parent gender differences decreased. Dyadic analyses revealed bidirectional influences. At 1;7, dyadic scores for words and MLUs displayed a descending pattern from mother—daughter, to mother—son, to father—daughter, to father—son dyads. At 2;0, the most and fewest words were reported in mother—daughter and mother—son dyads, respectively; and the longest and shortest MLUs in father—daughter and father—son dyads, respectively. The data raise questions about the ‘bridge hypothesis.’ They suggest that fathers are more likely to provide a bridge for daughters than for sons; daughters may play an active role in eliciting this behavior.

“…While there are conflicting reports in the literature, sex differences have been noted in a variety of behaviors and characteristics in very early infancy prior to extensive opportunity for modification by social interaction. Female infants are reported to exceed male infants in such characteristics as rate of maturation (Engel & Benson, 1968;Garai & Scheinfeld, 1968;Roche, 1968), tactile sensitivity (Bell & Costello, 1964;Lipsitt & Levy, 1959;Wolff, 1969), responsiveness to auditory stimulation (Friedman & Jacobs, 1981), period of alertness (Berg, Adkinson, & Strock, 1973), responsiveness to sweet taste (Nisbett & Gunvitz, 1970), recovery of attention following habituation (Friedman, Bruno, & Vietze, 1974), level of heart rate variability (Stamps & Porges, 1975), reflex smiles and rhythmical mouthing (Korner, 1969), mouth domination of hand-tomouth approach (Korner, 1973), time spent in sleep (Moss, 1967), and vo-calization to faces (Kagan, 1971). Male infants are reported to exceed female infants in such characteristics as size and weight (Garai & Scheinfeld, 1968), grip strength (Jacklin, Snow, & Maccoby, 1981), degree of startle response (Korner, 1969), irritability (Moss, 1967;Phillips, King, & DuBois, 1978), and incidence of pregnancy and birth complication and neonatal abnormalities (Bell, Weller, & Waldrop, 1971;Parmalee & Stern, 1972;Singer, Westphal, & Niswander, 1968).…”
