Object-naming deficits in developmental dyslexia

This paper reports two experiments which focus on the object naming deficits of dyslexic readers. In Experiment 1, dyslexic and normal readers were asked to name objects depicted by pictures or following their spoken definition. Ten-year-old dyslexics named fewer objects correctly than other children of a similar age, performing only as well as a younger group of 8-year-old normal readers. This was true irrespective of the modality through which they were tested. In terms of naming latency, however, they were similar to comparison groups. In Experiment 2, nine-year-old dyslexic and normal readers performed as well as each other in a receptive vocabulary test in which pictures had to be matched to spoken words. However, once again, on a picture naming test, the dyslexics did less well than controls. We argue that dyslexic children are subject to verbal naming difficulties which cannot be accounted for by generally low levels of vocabulary knowledge. Their problems are attributable not to difficulties in semantic representation but to difficulties with the lexical-phonological representation of spoken words they know. We propose that, in turn, these difficulties are related to their memory and reading problems.     

Diurnal patterning of eight activities in 14 species of muroid rodents

The diurnal patterning of locomotion, stereotypy, grooming, eating, drinking, sleeping, postural readjustment, and inactivity was studied in 14 species of muroid rodents in the laboratory using a visual observation technique.Microtus canicaudus, M. montanus, M. ochrogaster, andM. pennsylvanicus exhibited acyclic activity patterns, whilePeromyscus eremicus,P. gossypinus, P. leucopus, P. maniculatus bairdi, P. polionotus, Calomys callosus, Mus musculus, andOnychomys leucogaster displayed nocturnality in their behavioral patterning.Rhabdomys pumilio exhibited crepuscular activities andNeofiber alleni displayed a complex pattern of nocturnality. Species differed in total amount of time spent per day for all activities but eating. The acyclicity ofMicrotus species appears to be related to high metabolic rates and a semifossorial life-style.     

Influences of Writing Tasks on Students' Answers to Recall and Higher-Level Test Questions

This paper reports on two inter-related studies that examined the use of non-traditional writing strategies within secondary school science classrooms. The first study involved Year 10 students who incorporated one letter writing experience into the learning sequence when studying genetics. The second study was with Year 9 students who used both a non-traditional laboratory writing heuristic and letter writing as part of the learning sequence when studying a topic on light. The same teacher was involved in both case studies. A higher-level analogy question was added to the teacher-prepared tests for each study to examine if students who participated in writing-to-learn activities were able to perform significantly better as a group than a group of students who completed traditional teacher directed laboratory activities and note-taking. Results indicate that for the first study there was not a significant difference using t-test analysis, while for the second study involving two writing treatments there was a statistically significant difference using t-test analysis. There was no statistically significant difference in responses between treatment and control groups when answering low level recall questions for either case study. Student interviews indicated awareness by students of the metacognitive value gained by using the non-traditional writing types.     

The effect of intra- versus post-interview feedback during simulated practice interviews about child abuse

OBJECTIVE: This study compared the effectiveness of two types of instructor feedback (relative to no feedback) on investigative interviewers' ability to adhere to open-ended questions in simulated practice interviews about child abuse. METHOD: In one condition, feedback was provided at the end of each practice interview. In the other, the instructor stopped the interviewer at various stages during the practice interviews to provide feedback. The relative effect of these conditions was examined by measuring interviewers' performance in a standardized mock interview paradigm immediately prior to, immediately after, and 12 weeks after the practice and feedback sessions. RESULTS: Prior to and 12 weeks after the practice sessions were administered, there was no significant difference in participants' adherence to open-ended questions irrespective of the nature of the feedback, or whether feedback was received. At the immediate post-practice assessment interval, however, the participants who received feedback during the practice interviews performed better (M proportion of open-ended questions=.85, SD=.13) than the other participants (post-interview feedback M=.67, SD=.18, p<.001; no feedback M=.56, SD=.16, p<.001). This heightened use of open-ended questions was associated with a greater tendency among the interviewees to provide abuse-related details in response to open-ended questions (M=.91, SD=.11) compared to the other participants (post-interview feedback M=.77, SD=.15, p<.05; no feedback M=.69, SD=.16, p=.001). CONCLUSIONS: Different types of feedback can be differentially effective in training child abuse investigators to adhere to open-ended questions. The benefits of any training program, however, are likely to be short-lived without ongoing practice. PRACTICE IMPLICATIONS: A single study compared the relative effectiveness of two types of instructor feedback (relative to no feedback) on investigative interviewers' ability to adhere to open-ended questions in simulated practice interviews about child abuse. This research is relevant to trainers of investigative interviewers because there is currently large variability in the type of feedback employed in training programs. This study is one of the first to empirically demonstrate that different types of feedback may be differentially effective in improving the performance of investigative interviewers.

Conflict in the family: A continuing education course produced by the open university

This course, first presented by the Open University in 1980, is designed for independent study by people who, in the course of their working lives, come into contact with families suffering serious internal conflicts which place any members—adult or child—in danger of physical or emotional abuse in their own home. The course has been developed at a level which should make it a serious contribution to in-service training for a wide variety of professionals and experienced voluntary workers. It is unique in that it not only examines constructive and destructive aspects of conflict but also integrates written material (16 units) with an audiovisual component (8 TV programmes and 7 cassette tapes) on prevention, diagnosis and intervention relating to the whole spectrum of family conflict and violence including child abuse, sexual abuse, adolescent abuse, spouse abuse, abuse of and by the elderly and abuse of parents by their children. This paper provides a brief outline of the course aims, objectives and content together with information on its usage in the UK and the availability of certain components for international usage.
