The Acquisition of Communication Skills by People with Brain Injury: Some comparisons with children with autism

This research identifies the extent to which different contexts shape and modify the language and behaviours of four people with acquired brain injury. Comparisons are made with factors which can influence the language acquisition of children with autism because it is postulated that children with autism also have a particular brain injury. The comparison does not end there as the criteria for effective management necessary to nourish the communication skills of both groups appears similar. The four contexts used to shape and evaluate the language of people with brain injury include their own home, a residential camp with maximum support and enriched activity, a post camp period with comparable support, followed by a return to their own home with very limited support. Measures of communication skills demonstrate the success of the enriched camp facility. This was characterised by planning, structured support, and expectation of success from the participants. Their motivation and ability to communicate generally far exceeded the communication skills that each person with brain injury demonstrated when organised activity and sustained support is not available.     

Expertise Differences in the Comprehension of Visualizations: a Meta-Analysis of Eye-Tracking Research in Professional Domains

This meta-analysis integrates 296 effect sizes reported in eye-tracking research on expertise differences in the comprehension of visualizations. Three theories were evaluated: Ericsson and Kintsch’s (Psychol Rev 102:211–245, 1995) theory of long-term working memory, Haider and Frensch’s (J Exp Psychol Learn Mem Cognit 25:172–190, 1999) information-reduction hypothesis, and the holistic model of image perception of Kundel et al. (Radiology 242:396–402, 2007). Eye movement and performance data were cumulated from 819 experts, 187 intermediates, and 893 novices. In support of the evaluated theories, experts, when compared with non-experts, had shorter fixation durations, more fixations on task-relevant areas, and fewer fixations on task-redundant areas; experts also had longer saccades and shorter times to first fixate relevant information, owing to superiority in parafoveal processing and selective attention allocation. Eye movements, reaction time, and performance accuracy were moderated by characteristics of visualization (dynamics, realism, dimensionality, modality, and text annotation), task (complexity, time-on-task, and task control), and domain (sports, medicine, transportation, other). These findings are discussed in terms of their implications for theories of visual expertise in professional domains and their significance for the design of learning environments.     

Improving the Acquisition of Novel Vocabulary Through the Use of Imagery Interventions

The purpose of this study was to investigate the impact of imagery interventions on the vocabulary acquisition abilities of second grade students. A total of 15 students were randomly assigned to three different intervention conditions: Word Only, which involves the simple verbal presentation of a vocabulary word; Dual Coding, in which a picture was paired with the vocabulary word, and Image Creation, in which students were told to create a mental picture of the vocabulary word in their mind and draw it on paper. These students were taught a total of 21 vocabulary words: seven animal and habitat words, seven musical instrument terms, and seven science terms. A Latin square design was used, in which each group of students rotated through each of the interventions, being exposed to a different treatment condition for each category of words. Participants were measured on the number of words they were successfully able to acquire through the use of experimenter designed comprehension measures. While no statistical significance was shown between the interventions across the word categories, a significant difference was found between the Image Creation and Word Only interventions within the science terms category. Students also reported that the imagery interventions facilitated the ease with which they learned the words. The findings have implications for increasing the success of classroom instruction, specifically for presenting novel vocabulary words to early elementary learners using imagery methods.     

Using Paper Helicopters to Teach Statistical Process Control

This hands‐on project uses a paper helicopter to teach students how to distinguish between common and special causes of variability when developing and using statistical process control charts. It allows the student to experience a process that is out‐of‐control due to imprecise or incomplete product design specifications and to discover how the process can be brought into control through the use of standardized product specifications and associated construction procedures. It also allows the student to experience common causes of variability, to distinguish these from the special causes of variability resulting from the incomplete design specifications, and to discover how standardization reduces process variability. The project has been used in both undergraduate and MBA classes and demonstrates these concepts in a way that is easy for the student to understand and remember.     

Sameness-difference judgments inSaimiri sciureus based on volumetric cues

The rationale was to apply Piaget’s theory and methods to the study of the phylogenetic development of cognitive abilities. It was asked whether squirrel monkeys have the prerequisite skills for conservation of quantity, and, specifically, whether they might respond differentially to equivalent and unequivalent volumetric cues. All monkeys responded significantly and differentially to pairs of identical objects or pairs of objects similar only in volume vs. pairs of objects which differed in volume. It was concluded that squirrel monkeys have the prerequisite skills for the conservation of quantity. Discussion included methodological problems associated with demonstrating conservation in nonhumans as well as the potential usefulness of Piaget’s theory for phylogenetic studies of intelligence.     

The Impact of an SES-Based Model on a College's Undergraduate Admissions Outcomes

In Grutter vs. Bollinger, the U.S. Supreme Court ruled that the use of race as one factor, among many in admissions decisions is constitutional. It is not known, however, whether future legal opinions will continue to uphold the use of affirmative action policies. Some have argued that class-based preferences can achieve many of the same goals as in affirmative action while being more likely to withstand legal challenges. To date, no empirical studies have been conducted on the potential impact of a class-based admissions policy if implemented at an undergraduate institution. This paper reports on a study at a selective public college and compares a number of outcomes under three admissions models: the original admissions decisions, a purely academic model, and an socio-economic status (SES)-based model. The findings showed that use of the SES-based model would have led to a more academically qualified class than in the original admitted class while maintaining substantially greater student diversity that was found under the academic model. An admissions policy based on preferences for socio-economically disadvantaged applicants appears to hold promise for other colleges and universities with similar institutional and applicant characteristics. The ideas and research design reported in this paper are based on the doctoral dissertation study of the second author, Undergraduate Admissions Models Incorporating Socioeconomic Factors (Johnson, 2000).     

Mainstreaming the Hearing Impaired Student‐‐An Area of Preparation Responsibility for Teacher Training Programs: A Pilot Study

Interviewing, as an information‐gathering tool for prospective teachers of the deaf, was used to document the perspectives which deaf children, their parents, teachers and administrators bring to the mainstreaming process. Data revealed the different, and sometimes competing priorities of mainstreaming participants; these priorities are discussed in terms of their impact upon the success or failure of the mainstreaming process and the preparation responsibilities of teacher training programs.
