Associations Among Pubertal Development,Empathic Ability,and Neural Responses While Witnessing Peer Rejection in Adolescence

Links among concurrent and longitudinal changes in pubertal development and empathic ability from ages 10 to 13 and neural responses while witnessing peer rejection at age 13 were examined in 16 participants. More advanced pubertal development at age 13, and greater longitudinal increases in pubertal development, related to increased activity in regions underlying cognitive aspects of empathy. Likewise, at age 13 greater perspective taking related to activity in cognitive empathy‐related regions; however, affective components of empathy (empathic concern and personal distress) were associated with activity in both cognitive and affective pain‐related regions. Longitudinal increases in empathic ability related to cognitive and affective empathy‐related circuitry. Findings provide preliminary evidence that physical and cognitive‐emotional development relate to adolescents' neural responses when witnessing peer rejection.     

Analysis of Readex's Serial Set MARC records: Improving the data for the library catalog

Colorado State University Libraries (CSUL) purchased the digitized United States Congressional Serial Set, 1817–1994 and American State Papers (1789–1838) from the Readex Division of NewsBank, Inc. and, once funds and records were available, the accompanying MARC records. The breadth of information found in the Serial Set is described, along with the difficulties in using the print version (incorporated in the literature review, which includes citations of announcements of the digital collections and reviews of the software). The digital version of the Serial Set has its advantages, but there are additional rewards (much greater discovery opportunities) when items in the digital collection are directly accessible from the library catalog. The purchased MARC records, while overall excellent, had problems that needed to be corrected before they were loaded into CSUL's Innovative Interfaces library catalog. Patron access impact was used as a criterion when determining which of the records would be fixed before loading. High impact problems were identified and solutions derived for: multiple 245 (title) fields; 245 s indicator zero with titles beginning with a, an, or the; dollar sign used in text; fixed field date; languages; subject headings; creating proxy URLs; classification numbers; and author authority control (e.g. corporate entries and presidential entry errors).     

Using Focus Groups to Examine the Consequential Aspect of validity

How can focus groups be used to examine issues of consequential validity in large-scale assessment? In relation to a new large-scale assessment, what are teacher concerns, and how do these concerns differ by type of school district? What are the strengths and weaknesses in this approach to looking at consequential validity?     

Utility of Feedback Has a Greater Impact on Learning than Ease of Decoding

While feedback is a key facilitator of learning, researchers have yet to determine the ideal feedback process for optimal performance in learners. The current study investigates the combined effects of ease of decoding, and utility of feedback during learning. Accuracy and rate of learning were recorded alongside changes to the feedback related negativity (FRN), an event‐related potential (ERP) elicited by feedback stimuli. This study investigates the FRN within the context of future‐focused directive feedback (DF), in addition to past‐focused evaluative feedback (EF) typically seen in the neuroscience literature. Results indicate a main effect of utility together with an interaction with ease of decoding on the accuracy data, but only the main effect of utility on learning rate. DF produced an FRN, like EF, which was then larger during high‐utility feedback, specifically following negative EF or when hard‐to‐decode. Implications and future research directions are discussed.     

Testing Alternative Hypotheses Regarding the Association Between Behavioral Inhibition and Language Development in Toddlerhood

Studies have reported an inverse association between language development and behavioral inhibition or shyness across childhood, but the direction of this association remains unclear. This study tested alternative hypotheses regarding this association in a large sample of toddlers. Data on behavioral inhibition and expressive and receptive language abilities were collected from 816 twins at ages 14, 20, and 24 months. Growth and regression models were fit to the data to assess the longitudinal associations between behavioral inhibition and language development from 14 to 24 months. Overall, there were significant associations between behavioral inhibition and expressive language, and minimal associations with receptive language, indicating that the association is better explained by reticence to respond rather than deficient language development.
