Awe in nature fosters science identity and belonging in participatory scientists during an eclipse
The interactions between people and nature are complex, with research suggesting that people often report feeling awe in nature, including in relation to eclipses. Less is known about if feelings of awe in nature can drive science outcomes. The current study aimed to understand the relationship between observing a total eclipse in nature, awe and science identity and belonging for individuals involved in a participatory science study of animal be…
Perceptions of STEM Barriers in Adolescence
This 2-year longitudinal study examines the relations between math and science interest, STEM identity, and perceptions of STEM barriers in 280 (68% female; M age = 15.27) adolescents in the United States and the United Kingdom. Structural equation models indicated that higher math interest at time 1 was positively associated with overall STEM identity at time 2, and greater STEM identity at time 2 was related to fewer perceptions of barriers to …
Developmental Trajectories of Adolescents’ Math Motivation
Reciprocal Associations Between Science Efficacy, STEM Identity and Scientist Career Interest Among Adolescent Girls within the Context of Informal Science Learning
Limited research has explored the longitudinal pathway to youth career interests via identity and efficacy together. This study examined the longitudinal associations between science efficacy, STEM (science, technology, engineering and math) identity, and scientist career interest among girls who are historically considered as an underrepresented group among scientists. The sample included 308 girls (M age = 15.22, SD age = 1.66; 42.8% White) fro…
Children's and adolescents’ evaluations of wealth‐related STEM inequality
The fields of science, technology, engineering, and mathematics (STEM) are rife with inequalities and under-representation that have their roots in childhood. While researchers have focused on gender and race/ethnicity as two key dimensions of inequality, less attention has been paid to wealth. To this end, and drawing from the Social Reasoning Development approach, we examined children's and adolescents' perceptions of STEM ability and access to…
Promoting Diverse Youth’s Career Development through Informal Science Learning
Little research has examined the associations between perceived inclusivity within informal science learning sites, youth program belonging and perceptions of program career preparation. This study explored relations between these factors at three timepoints (T1 = start of program, T2 = 3 months and T3 = 12 months after start). Participants were a diverse sample of 209 adolescents participating in STEM youth programs within informal science learn…
Interest, Mindsets and Engagement
Preparing the Next Generation for STEM
Science, technology, engineering, and math (STEM) workers need both motivation and interpersonal skills in STEM disciplines. The aims of the study were to identify clusters of adolescents who vary in math and science motivation and interpersonal skills and to explore what factors are related to membership in a high math and science motivation and interpersonal skills cluster. Participants included 467 adolescents (312 female; Mage = 15.12 to SD =…
Gender Stereotypes and Peer Selection in STEM Domains Among Children and Adolescents
Gender stereotypes are harmful for girls' enrollment and performance in science and mathematics. So far, less is known about children's and adolescents' stereotypes regarding technology and engineering. In the current study, participants' ( N = 1,206, girls n = 623; 5-17-years-old, M = 8.63, SD = 2.81) gender stereotypes for each of the STEM (science, technology, engineering, and mathematics) domains were assessed along with the relation between …
Impact of Youth and Adult Informal Science Educators on Youth Learning at Exhibits
The impact of educators in informal science learning sites (ISLS) remains understudied from the perspective of youth visitors. Less is known about whether engagement with educators differs based on the age and gender of both visitor and educator. Here, visitors (5–17 years old) to six ISLS in the United States and United Kingdom (n = 488, female n = 244) were surveyed following an interaction with either a youth (14–18 -years old) or adult educat…
The Relations and Role of Social Competencies and Belonging with Math and Science Interest and Efficacy for Adolescents in Informal STEM Programs
Adolescence represents a developmental period of waning academic motivation, particularly in STEM domains. To combat this, better understanding the factors that might foster STEM motivation and interest is of importance. Social factors like social competencies and feelings of belonging become increasingly important in adolescence. The current study investigated structural relations between social competencies, feelings of belonging to an informal…
Learning hand in hand
Developmental science research often involves research questions developed by academic teams, which are tested within community or educational settings. In this piece, we outline the importance of research-practice partnerships, which involve both research and practice-based partners collaborating at each stage of the research process. We articulate challenges and benefits of these partnerships for developmental science research, identify relevan…
Brief communication
Objectives Previously, we found that maximum ingested bite size (V b ), the largest piece of food an animal can consume without biting it into smaller pieces first, isometrically scales relative to body size in strepsirrhines and with negative allometry in anthropoids. In the current study, we rectify the omission of great apes from the earlier sample to now characterize the V b of the entire size‐range of the order. Materials and Methods Five go…
The gaits of marsupials and the evolution of diagonal‐sequence walking in primates
OBJECTIVES: Documenting the variety of quadrupedal walking gaits in a variety of marsupials (arboreal vs. terrestrial, with and without grasping hind feet), to aid in developing and refining a general theory of gait evolution in primates. MATERIALS AND METHODS: Video records of koalas, ringtail possums, tree kangaroos, sugar gliders, squirrel gliders, wombats, numbats, quolls, a thylacine, and an opossum walking on a variety of substrates were ma…
A primate with a Panda's thumb
OBJECTIVES: Accessory digits have evolved independently within several mammalian lineages. Most notable among these is the pseudothumb of the giant panda, which has long been considered one of the most extraordinary examples of contingent evolution. To date, no primate has been documented to possess such an adaptation. Here, we investigate the presence of this structure within the aye-aye (Daubentonia madagascariensis), a species renowned for sev…
The ligamentum teres femoris in orangutans
OBJECTIVES: It is widely viewed that orangutans lack a ligamentum teres femoris (LTF) inserting on the femoral head because orangutans lack a distinct fovea capitis. Orangutans employ acrobatic quadrumanous clambering that requires a high level of hip joint mobility, and the absence of an LTF is believed to be an adaptation to increase hip mobility. However, there are conflicting reports in the literature about whether there may be a different LT…
Exudativory in the Asian loris, Nycticebus
OBJECTIVES: Slow lorises (Nycticebus spp.) are obligate exudativores that gouge tree bark. Dental adaptations for gouging within marmosets, the only other known primate obligate exudativore, are well-known but dental adaptations in Nycticebus are largely unidentified. In an effort to more completely understand potential dental adaptions within Nycticebus and the evolution of this dietary niche within Primates as an order, the present study examin…
Comparing apples and oranges—the influence of food mechanical properties on ingestive bite sizes in lemurs
Previously we found that Maximum Ingested Bite Size ( V b )—the largest piece of food that an animal will ingest whole without biting first—scales isometrically with body size in 17 species of strepsirrhines at the Duke Lemur Center (DLC). However, because this earlier study focused on only three food types (two with similar mechanical properties), it did not yield results that were easily applied to describing the broad diets of these taxa. Expr…
Craniomandibular signals of diet in adapids
OBJECTIVES: The craniomandibular morphology of the adapid primates of Europe, especially Adapis and Leptadapis (sensu lato), suggests that they possessed enormous jaw adductor muscles. The goal of this study is to estimate jaw adductor muscle mass, physiological cross-sectional area (PCSA), and fiber length in adapid primates from the Eocene of Europe. We also estimated muscle leverage, bite force, and gape parameters. MATERIALS AND METHODS: We u…
Maximum ingested food size in captive anthropoids
OBJECTIVES: Maximum ingested food size (Vb ) is an empirically tested performance variable that can shed light on feeding energetics and adaptation in the masticatory system. Until now, this variable had been tested in strepsirrhines alone among primates. Here, we present the first data on Vb in a broad sample of anthropoid primates and describe scaling patterns. MATERIALS AND METHODS: Vb data on anthropoids were collected under captive condition…
Characterizing felid tooth marking and gross bone damage patterns using GIS image analysis
Body size in African Middle Pleistocene Homo
It is generally accepted that archaic humans of the African later Early and early Middle Pleistocene constituted the source population for anatomically modern humans . Due to limited fossil and archaeological records, however, relatively little is known about the morphology, behaviour and ecology of these presumed ancestors of modern humans. Fragmentary fossils (variously attributed to Homo heidelbergensis , H . rhodesiensis and H . helmei ) from…
The role of tooth enamel mechanical properties in primate dietary adaptation
Primate teeth adapt to the physical properties of foods in a variety of ways including changes in occlusal morphology, enamel thickness, and overall size. We conducted a comparative study of extant primates to examine whether their teeth also adapt to foods through variation in the mechanical properties of the enamel. Nanoindentation techniques were used to map profiles of elastic modulus and hardness across tooth sections from the enamel‐dentin …
Adaptation to hard-object feeding in sea otters and hominins
Maximum ingested food size in captive strepsirrhine primates
Little is known about ingested food size ( V b ) in primates, even though this variable has potentially important effects on food intake and processing. This study provides the first data on V b in strepsirrhine primates using a captive sample of 17 species. These data can be used for generating and testing models of feeding energetics. Strepsirrhines are of interest because they are hypometabolic and chewing rate and daily feeding time do not sh…
