Indexing Early Visual Memory Durability in Infancy

The goal was to examine the scope and development of early visual memory durability. We investigated individual- and age-related differences across three unique tasks in 6- to 12-month-olds (M_age = 8.87, N = 49) by examining the effect of increased delay on memory performance. Results suggest longer-term memory processes are quantifiable by 8 months using a modified Change Detection paradigm and spatial-attention cueing processes are quantifiable by 10 months using a modified Delayed Response paradigm, utilizing 500–1,250 ms delays. Performance improved from 6 to 12 months and longer delays impaired performance. We found no evidence for success on the Delayed Match Retrieval task at any age. These outcomes help inform our understanding of infant visual memory durability and its emergence throughout early development.     

College Students' Experiences of Childhood Developmental Traumatic Stress: Resilience,First‐Year Academic Performance,and Substance Use

Developmental trauma—distressing childhood experiences that include mistreatment, interpersonal violence, abuse, assault, and neglect—is associated with substance use and poor academic performance. The authors investigated the links between developmental trauma, grade point average, substance use, and resilience among first‐year college students (N = 169). The results indicate there is a significant relationship between cumulative trauma and self‐reported substance use.     

Researching the Scholarship of Teaching and Learning: An Analysis of Current Curriculum Practices

The purpose of this study was to analyze how instructors designed courses for scholarship of teaching and learning initiatives. The case studies and qualitative analyses of the data revealed that some instructors are approaching teaching as an investigative process. Informed by multiple assessment methods, the participating instructors explored how changes in course designs can improve student learning and development. The results of this study illustrate that these instructors reflected on their course designs and emphasized the quality of student learning and its improvement, which helps to address the public's expectations of higher education institutions as centers of academic excellence.     

Children's Metacognition About Reading: issues in Definition,Measurement, and Instruction

Metacognition has become a popular term in theories of cognitive development and reading. What children know about the goals, tasks, and strategies of reading can influence how well they plan and monitor their own reading. Despite the appeal of metacognition and the emphasis on executive management of reading, there have been relatively few empirical studies that measure or promote children's metacognition about reading. This article briefly reviews some key studies of children's knowledge about reading and identifies some difficulties in defining and measuring metacognition. An Index of Reading Awareness (IRA) is offered as an informal assessment of metacognition derived from both theory and empirical data that can be used to measure children's understanding of reading comprehension processes. Data are presented illustrating that the instrument is sensitive to developmental and instructional differences in children's metacognition about reading. It is argued that the usefulness of the term metacognition depends on the development of both formal and informal tests of children's knowledge about reading and effective instruction that promotes metacognition.     

Rats in a levered T-maze task show evidence of time–place discriminations in two different measures

It is difficult for rats to learn to go to an arm of a T-maze to receive food that is dependent on the time of day, unless the amount of food in each daily session is different. In the same task, rats show evidence of time–place discriminations if they are required to press levers in the arms of the T-maze, but learning is only evident when the first lever press is considered, and not the first arm visited. These data suggest that rats struggle to use time as a discriminative stimulus unless the rewards/events differ in some dimension, or unless the goal locations can be visited prior to making a response. If both of these conditions are met in the same task, it might be possible to compare time–place learning in two different measures that essentially indicate performance before and after entering the arms of the T-maze. In the present study, we investigated time–place learning in rats with a levered T-maze task in which the amounts of food varied depending on the time of day. The first arm choices and first lever presses both indicated that the rats had acquired time–place discriminations, and both of these measures became significantly different from chance during the same block. However, there were subtle differences between the two measures, which suggest that time–place discrimination is aided by visiting the goal locations.     

Nagging,noobs and new tricks – students’ perceptions of school as a context for digital technology use

While digital technology is an integral feature of contemporary education, schools are often presumed to constrain and compromise students’ uses of technology. This paper investigates students’ experiences of school as a context for digital technology use. Drawing upon survey data from three Australian secondary schools (n = 1174), this paper considers the various ways in which students use digital devices and applications “in school” and “for school”. After highlighting trends and differences across a range of digital devices and practices, the paper explores the ways in which students perceive school as a limiting and/or enabling setting for technology use. The findings point to a number of ways that schools act to extend as well as curtail student engagement with technology. This paper concludes by considering the possible ways that schools might work to further support and/or enhance students’ technology experiences.
