To investigate students' self-monitoring practice and effects of educational level and task importance on self-monitoring, 510 students, varying in educational level from elementary through graduate school, reported the self-monitoring strategies they employed in three learning situations with different levels of task importance. The study…

We examined 3- to 6-year-old children's understanding of their own and another's false beliefs in two experiments using diverse deceptive box and unexpected transfer tasks. Tasks in the first experiment required the child to think about an absent person's responses to questions, whereas those in the second experiment used a confederate present…

The authors estimate weighted mean values for nine information processing parameters for older adults using the Card, Moran, and Newell (1983) Model Human Processor model. The authors validate a subset of these parameters by modeling two mobile phone tasks using two different phones and comparing model predictions to a sample of younger (N = 20;…

This study was designed to determine whether modifying the task characteristics of the Stage 6 sensorimotor means-end problem (by introducing additional visual cues) aided task solution in children. Subjects were 80 children, ages 20-33 months. (CS)

A total of 451 adults participated in 2 studies of the causes of age differences that occur in cognitive performance when tasks increase in complexity. Results support the hypothesis that more complex cognitive tasks place greater demands on a working memory resource that declines as age increases. (LB)

The role of categorical versus associative relations in 5-, 7-, and 11-year-old children's true and false memories was examined using the Deese--Roediger--McDermott (DRM) paradigm and categorized lists of pictures or words with or without category labels as primes. For true items, recall increased with age and categorized lists were better…

Toddlers' symbolic understanding of iconic models was assessed through 2 comprehension-based tasks: 1 based on looking and 1 requiring manual selection of the target object. Toddlers received either iconic models or photographs of models as the symbolic referent. Overall, 18-month-olds performed poorly, and both 22- and 26-month-olds performed…

Behavioral aspects of self-regulation, including controlling and directing actions, paying attention, and remembering instructions, are critical for successful functioning in preschool and elementary school. In recent years, several direct assessments of these skills have appeared, but few studies provide complete psychometric data and many are…

During adolescence the body undergoes many physical changes. These changes necessitate an updating of internal models of action. Here, we tested the hypothesis that internal models undergo refinement between adolescence and adulthood. We investigated the chronometry of executed and imagined hand actions, which relies on internal models, in 40…

Age-related changes in the use of verbal processes for the efficient switching between tasks were investigated in 5-year-old children (N = 32, M age = 5.9 years) and 9-year-old children (N = 32, M age = 9.4 years). Task switching was assessed by means of a cued switching paradigm to examine two switching components: (a) to maintain and select and…

Age-related differences (9- to 15-year-olds) in the neural correlates of mapping from phonology to orthography were examined with functional magnetic resonance imaging (fMRI). Participants were asked to determine if two spoken words had the same spelling for the rime (corresponding letters after the first consonant or consonant cluster). Some of…

This study investigated age-related differences in working memory and inhibitory control (WMIC) in 3 1/2-, 4-, and 4 1/2-year-olds and how these differences were associated with differences in regulatory aspects of temperament, language comprehension, and brain electrical activity. A series of cognitive control tasks was administered to measure…

Presents a developmental study of children's knowledge and understanding of the interaction of variables which affect memory storage. The study focuses on the children's awareness of their own memory. Subjects were 40 five- and ten-year-old children. (BD)

Forty toddlers, 1 1/2 to 3 1/2 years of age, and 8 adults, searched for stickers that were hidden underneath two discretely different classes of objects embedded in arrays containing several classes. Study results suggest that the children appear to have been attempting to determine which kinds of choices were the wrong ones. (Author/RWB)
