Partial Verbal Redundancy in Multimedia Presentations for Writing Strategy Instruction

Multimedia instructional materials require learners to select, organize, and integrate information across multiple modalities. To facilitate these comprehension processes, a variety of multimedia design principles have been proposed. This study further explores the redundancy principle by manipulating the degree of partial redundancy between written and narrated content. Ninety high school students learned about cohesion via animated lesson videos from the Writing Pal intelligent tutoring system. Videos were crafted such that narrated and onscreen written content overlapped by 10%, 26%, or 50%. Across conditions, students gained significantly in their knowledge of cohesion‐building strategies and the effects of cohesion on writing quality. However, degree of redundancy did not influence learning gains. Additionally, although more‐skilled readers outperformed less‐skilled readers, reading skill did not interact with the degree of redundancy. These results provide evidence that a broad range of partially redundant multimedia materials may be viable instructional tools that benefit diverse learners.

Understanding the effects of one's actions upon hidden objects and the development of search behaviour in 7‐month‐old infants

Infants' understanding of how their actions affect the visibility of hidden objects may be a crucial aspect of the development of search behaviour. To investigate this possibility, 7‐month‐old infants took part in a two‐day training study. At the start of the first session, and at the end of the second, all infants performed a search task with a hiding‐well. On both days, infants had an additional training experience. The ‘Agency group’ learnt to spin a turntable to reveal a hidden toy, whilst the ‘Means‐End’ group learnt the same means‐end motor action, but the toy was always visible. The Agency group showed greater improvement on the hiding‐well search task following their training experience. We suggest that the Agency group's turntable experience was effective because it provided the experience of bringing objects back into visibility by one's actions. Further, the performance of the Agency group demonstrates generalized transfer of learning across situations with both different motor actions and stimuli in infants as young as 7 months.     

Treating Hypochondriasis with Interpersonal Psychotherapy

The treatment of hypochondriacal patients can be conceptualized as taking one of three approaches. These typically address one of the following questions: 1) “Should the patient be preoccupied?” 2) “Why is the patient preoccupied?” 3) “What are the interpersonal consequences of being preoccupied?” Interpersonal Psychotherapy (IPT) is specifically designed to address the last of these questions. IPT focuses on understanding the patient’s real distress, exploring the patient’s maladaptive communications, and modifying those communications so that others are more able to meet the patient’s attachment needs. With a focus on communication in a time-limited frame, fostered by a strong collaborative relationship, IPT appears to be an effective method of reducing hypochondriacal behavior.
