This study of the haptic processing of 9 children with specific language impairment and 9 normal-language children (ages 5-7) found that both groups performed similarly when the response modality was tactile and task requirements were minimal and performed differently when response demands included cross-modal processing or increased symbolic and…

The latency and amplitude of the P300, an event-related potential, during the performance of a memory-scanning task were used as indices of the efficiency of information processing that may mediate individual differences in intelligence. Results with 61 female college students contradict a pure speed of processing explanation of the relationship…

Two experiments used Headed Records memory model to examine preschoolers' performance on a variation of Perner's Smarties task, a false-beliefs test. Data indicated that when the computational demands imposed by the original task are reduced, young children can and do remember what they had thought about the contents of a tube even after its true…

Studied structures and relationships in one-step additive and multiplicative problems solved by 450 students in grades 2, 3, and 4. Results show that the facility ratio of the problems differs by structure, situation, and the sequence of data. The ability to solve one-step problems increases with age, but relative problem difficulty is grade…

These proceedings contain the papers of the International Conference on Mobile Learning 2013, which was organised by the International Association for Development of the Information Society, in Lisbon, Portugal, March 14-16, 2013. The Mobile Learning 2013 International Conference seeks to provide a forum for the presentation and discussion of…

In today's knowledge economy, technology is utilized more than ever to deliver instructional material to the learner. Nonetheless, information may not always be presented in a manner that maximizes the learning experience, resulting in a negative impact on learning outcomes. Drawing on the Task-Technology Fit model, a research framework was…

Six series of experiments (11 individual experiments involving over 150 subjects) were conducted to further extend automatic/controlled processing research to command and control mission-specific training. The issues examined in these experiments were related to retention of task-component skills of amount of practice, component training for…

The difficulty of understanding embedded sentences is discussed in relation to Bever's hypothesis: if a sentence segment has a double function by means of the same processing strategy it is difficult to interpret the sentence. An alternative to this theory is proposed due to the author's experiments. (SCC)

Development of toddlers' combinatorial skills was examined in the domains of object manipulation, symbolic play, motor imitation, language, and peer interaction. Additionally, task demands that might produce variations in age-related patterns within or between domains were examined. Data were collected in free play sessions and during structured…

A study of whether perceptual processes of children can be viewed within a structuralist frame of reference and whether the concept of the group of transformations and related notions can be used to formulate perceptual phenomena and to predict experimental results. (Author/CS)

This study explores the extent to which scores on four separate complex reasoning solution processes could predict performance on difficult problems. Definitions are provided for the four processes--intra-sentence processing, inter-sentence processing, ordering, and collecting--and previous work done in the field is outlined. The procedures used…

This study examines the development of children's preference for task difficulty levels. Subjects were 78 boys and 66 girls, aged 63 to 105 months. The sample was separated into older and younger groups. Within each age group, half the children of each sex were randomly assigned to one of two forms to test their level of aspiration. Subjects were…

This paper describes an approach to task analysis which seeks to identify potential sources of difficulty in the self-discovery of improved procedures by students who have been taught simpler procedures. The approach considers novices' procedures in terms of the changes needed to produce an expert procedure; the knowledge required to make those…

Three studies compared learning and problem-solving performances of normal and familially-retarded children on tasks differing in complexity, and one study investigated motivational-personality differences. Main purpose of the first three studies was to investigate the controversy between developmental and defect theorists in mental retardation.…
