Peer Influence Via Instagram: Effects on Brain and Behavior in Adolescence and Young Adulthood

Mobile social media often feature the ability to “Like” content posted by others. This study examined the effect of Likes on youths' neural and behavioral responses to photographs. High school and college students (N = 61, ages 13–21) viewed theirs and others' Instagram photographs while undergoing functional Magnetic Resonance Imaging (fMRI). Participants more often Liked photographs that appeared to have received many (vs. few) Likes. Popular photographs elicited greater activity in multiple brain regions, including the nucleus accumbens (NAcc), a hub of the brain's reward circuitry. NAcc responsivity increased with age for high school but not college students. When viewing images depicting risk‐taking (vs. nonrisky photographs), high school students, but not college students, showed decreased activation of neural regions implicated in cognitive control.     

Sixteen myths about online teaching and learning in higher education: Don’t believe everything you hear

Conclusion Quality education through online learning depends on clarity of goals, sound e-pedagogy, committed and dedicated learners and instructors, excellent support from administrators and staff and opportunities to practice application of new knowledge and skills. It also depends on a reasoned view of online learning — not subscribing to myths without questioning them. In the cases where the myths contain elements of truth, we must seek methods to overcome limitations of a medium that offers great potential for the present and the future     

Understanding instructional design effects by differentiated measurement of intrinsic,extraneous, and germane cognitive load

Instructional Science - Instructional design deals with the optimization of learning processes. To achieve this, three aspects need to be considered: (1) the learning task itself, (2) the design of...

Young Children's Comprehension of Pretend Episodes: The Integration of Successive Actions

In 3 experiments, children's comprehension of successive pretend actions was examined. In Experiment 1, children (25–38 months) watched 2 linked actions (e.g., a puppet poured pretend cereal or powder into a bowl, and then pretended to feed the contents of the bowl to a toy animal). Children realized that the pretend substance was incorporated into the second action. In Experiment 2, children (24–39 months) again watched 2 linked actions (e.g., a puppet poured pretend milk or powder into a container, and then pretended to tip the contents of the container over a toy animal). They realized that the animal would become "milky" or "powdery." In Experiment 3, children (25–36 months) drew similar conclusions regarding a substitute rather than an imaginary entity. The results are discussed with reference to children's causal understanding, their capacity for talking about objects and events in terms of their make-believe and real status, and the processes underlying pretense comprehension.     

Groupitizing reflects conceptual developments in math cognition and inequities in math achievement from childhood through adolescence

Understanding the cognitive processes central to mathematical development is crucial to addressing systemic inequities in math achievement. We investigate the “Groupitizing” ability in 1209 third to eighth graders (mean age at first timepoint = 10.48, 586 girls, 39.16% Asian, 28.88% Hispanic/Latino, 18.51% White), a process that captures the ability to use grouping cues to access the exact value of a set. Groupitizing improves each year from late childhood to early adolescence (d = 3.29), is a central predictor of math achievement (beta weight = .30), is linked to conceptual processes in mathematics (minimum d = 0.69), and helps explain the dynamic between the ongoing development of non-symbolic number concepts, systemic educational inequities in school associated with SES, and mathematics achievement (minimum beta weight = .11) in ways that explicit symbolic measures may miss.
