Enabling a young man with minimal motor behavior to manage independently his leisure television engagement

Persons with severe spastic tetraparesis and minimal motor behavior may be confined to a wheelchair or bed and have virtually no chances of constructive engagement with their immediate environment. A possible way to modify this situation may involve the use of technology. The present study (a) assessed specific technology to enable a young adult to manage his leisure television engagement independently and (b) carried out a social validation assessment of the technology-supported performance involving 90 teacher trainees as raters. The intervention period with the new technology included 67 sessions, during which the participant performed independently 392 of the 408 television-management responses, i.e., turning on the television, finding a channel with a preferred program, setting the volume, and turning off the television. He also indicated preference for using the technology as opposed to not using it. The raters provided relatively high (positive) scores for the technology-supported performance compared to the baseline performance. Implications of the findings are discussed.     

An enriched teaching program for reducing resistance and indices of unhappiness among individuals with profound multiple disabilities

We evaluated an enriched teaching program for reducing resistance and indices of unhappiness displayed by 3 individuals with profound multiple disabilities during teaching sessions. The program involved presentation of preferred activities before, during, and after each teaching session, discontinuation of identified nonpreferred activities, and a brief break and preferred activity following occurrence of resistance. Implementation of the enriched teaching program was accompanied by reductions in resistance and indices of unhappiness for each participant. Results also indicated no negative impact of the program on participant performance of the teaching steps or staff teaching proficiency. Staff questionnaire responses provided a degree of social validation for the observed changes in that staff reported the participants liked the enriched teaching program more than the traditional teaching process. Directions for future research discussed include identifying critical aspects of the overall program and the potential relation between teaching proficiency and the program's enrichment effectiveness.     

Written lists as mediating stimuli in the matching-to-sample performances of individuals with mental retardation.

Students with mental retardation learned to write lists in order to perform a matching task that they could not do otherwise. After an initial assessment phase, reinforcement was arranged in the computerized tasks to follow selection of the six pictures that were identical to those in the six-picture samples presented. In Study 1, even though the participants wrote a list of the names of the six sample pictures on each trial, read a list, or did both, they often made errors when a brief delay preceded picture selection. In contrast, performance was nearly perfect when a list was written, read, and remained available at the time of picture selection, suggesting that the list served to mediate the delays. Study 2 examined the stimulus control by two- and six-picture samples over the list writing. Early during testing, 1 participant refrained from writing lists on two-picture trials but wrote lists on six-picture trials, thereby maximizing reinforcement and minimizing its delay; the other participant showed this pattern of list writing after supplemental training. The studies suggest methods for establishing a rudimentary repertoire of mediating behavior that has relevance for teaching instruction-following skills in natural settings.     

Social processing improves recall performance

One recent theory (Dunbar, 2003) has highlighted the importance that processing social information might have had on the evolution of human cognition. Based on an analysis of that theory, researchers predicted that processing information in a social manner would improve recall performance in comparison with nonsocial processing. In order to test this prediction, three experiments were conducted in which participants studied 30-item word lists that were composed of common character traits (Experiment 1) or common category exem-plars (Experiments 2 and 3). Next, participants reviewed 5 list items that were purportedly recalled by either a group member or the computer. Finally, after a brief distractor task, participants were asked to complete an individual recall test for all of the items on the original 30-item list. Of primary interest was recall performance for the list items that were purportedly recalled by either another participant or the computer. We observed that recall performance for list items purportedly recalled by another participant was superior to that for items that were recalled by the computer.     

The Effects of Text Structure Discrimination Training on the Writing Performance of Students with Learning Disabilities

The purpose of this study was to examine whether teaching three participants with learning disabilities to name and identify critical components (i.e., opening sentence, detail sentences, and key words) for four expository text structures, and to discriminate between well-written and poorly written components would improve their expository writing performance. After instruction, one participant immediately improved her expository paragraph writing skills. However, two participants needed additional instruction and feedback on their writing before their paragraph writing improved. Social validation of the study outcomes was assessed by comparing participants' paragraphs before and after instruction to paragraphs produced by same age peers without disabilities. After instruction, participants' paragraph scores were above the mean score of the normative comparison group. Implications for teaching writing skills to students with learning disabilities, and suggestions for future research are discussed.     

Handwriting or Typewriting? The Influence of Pen- or Keyboard-Based Writing Training on Reading and Writing Performance in Preschool Children

Digital writing devices associated with the use of computers, tablet PCs, or mobile phones are increasingly replacing writing by hand. It is, however, controversially discussed how writing modes influence reading and writing performance in children at the start of literacy. On the one hand, the easiness of typing on digital devices may accelerate reading and writing in young children, who have less developed sensory-motor skills. On the other hand, the meaningful coupling between action and perception during handwriting, which establishes sensory-motor memory traces, could facilitate written language acquisition. In order to decide between these theoretical alternatives, for the present study, we developed an intense training program for preschool children attending the German kindergarten with 16 training sessions. Using closely matched letter learning games, eight letters of the German alphabet were trained either by handwriting with a pen on a sheet of paper or by typing on a computer keyboard. Letter recognition, naming, and writing performance as well as word reading and writing performance were assessed. Results did not indicate a superiority of typing training over handwriting training in any of these tasks. In contrast, handwriting training was superior to typing training in word writing, and, as a tendency, in word reading. The results of our study, therefore, support theories of action-perception coupling assuming a facilitatory influence of sensory-motor representations established during handwriting on reading and writing.     

A word-finding computer program with a dynamic lexical-semantic memory for patients with anomia using an intelligent speech prosthesis

A computer program for a portable microprocessor has been developed which aids anomic patients in finding words given clues about the target word. Over time the lexical-semantic memory is reorganized automatically depending on the frequency of word usage by an individual patient. Words can be added or deleted to fit the patient's idiosyncratic lexicon. A clinical example is given. The program is being tested with a variety of aphasic-anomic patients with major word-finding difficulties.     

SOCIAL VALIDATION AND TRAINING OF EMERGENCY FIRE SAFETY SKILLS FOR POTENTIAL INJURY PREVENTION AND LIFE SAVING

A multifaceted behavioral program designed to teach emergency fire escape procedures to children was evaluated in a multiple-baseline design. Five children were trained to respond correctly to nine home emergency fire situations under simulated conditions. The situations and responses focused upon in training were identified by a social validation procedure involving consultation with several safety agencies, including the direct input of firefighters. Training, carried out in simulated bedrooms at school, resulted in significant improvements in both overt behavior and self-report of fire safety skills. The gains were maintained at a post-check assessment 2 weeks after training had been terminated. The results are discussed in relation both to the importance of social validation of targets and outcomes and the implications for further research in assessing and developing emergency response skills.     

Using a Computer as an Environmental Facilitator to Promote Post-Head Injury Social Role Resumption

Abstract

The purpose of this case study was to determine if an adult man with traumatic brain injury could use a computer as an environmental facilitator to assume adult social roles post-injury. The participant received four months of intervention in which (a) modifications to the computer's internal system, monitor, and keyboard were made, (b) the participant received instruction in adapted word processing and e-mail packages, and (c) the participant was provided with computer-related activities that were designed to enhance his participation in desired social roles. Participant observation and qualitative interview methods were used as data collection and analysis processes. As a result of his participation in the intervention, the participant was able to (a) re-establish his roles as a brother and an adult son, (b) develop and maintain an extended family of others beyond his family of origin, and (c) create a more satisfying adult work role that has brought greater meaning to his post-injury life.     

Language comprehension and probe-list memory

Experiments were performed using probe-word recognition methodology in which participants read sentences that were presented 1 word at a time and were then shown a probe word and had to make a speeded response indicating whether the word had occurred in the sentence. One experiment showed that response times to probe words increased with the size of the set of candidate probes. The other experiments showed that the effects caused by name repetition in circumstances in which the repeated name was co-referential also occurred when the repeated name was not co-referential and when the order of words in a sentence was scrambled. The results suggest that responses in the task can be based on probe-list memory, a mental representation created to keep track of those words that the participant believes are likely to be probed, and that the use of the task to make inferences about language comprehension should be accompanied by controls ruling out such strategies.     

Virtual social environments as a tool for psychological assessment: dynamics of interaction with a virtual spouse

Computer games are advocated as a promising tool bridging the gap between the controllability of a lab experiment and the mundane realism of a field experiment. At the same time, many authors stress the importance of observing real behavior instead of asking participants about possible or intended behaviors. In this article, the authors introduce an online virtual social environment, which is inhabited by autonomous agents including the virtual spouse of the participant. Participants can freely explore the virtual world and interact with any other inhabitant, allowing the expression of spontaneous and unprompted behavior. The authors investigated the usefulness of this game for the assessment of interactions with a virtual spouse and their relations to intimacy and autonomy motivation as well as relationship satisfaction with the real-life partner. Both the intimacy motive and the satisfaction with the real-world relationship showed significant correlations with aggregated in-game behavior, which shows that some sort of transference between the real world and the virtual world took place. In addition, a process analysis of interaction quality revealed that relationship satisfaction and intimacy motive had different effects on the initial status and the time course of the interaction quality. Implications for psychological assessment using virtual social environments are discussed.     

An eye-movement-contingent probe paradigm

A new eye-movement-contingent probe task is presented in which readers’ eye movements are monitored as they read sentences and respond to a probe word; the timing of the display of the probe word is dependent on fixation of a target word. The present study examined semantic priming effects. The target word was either related (doctor) or unrelated (lawyer) to the probe word (nurse), and the probe appeared 120, 250, 500, or 750msec after the reader first fixated on the target word. When the probe word appeared (in the location of the target word), the rest of the sentence disappeared until the participant named the probe word. Then the sentence reappeared, and the participant continued reading the sentence. Naming times to the probe word were recorded, as was sentence reading time and the eye movement behavior relative to the onset of the probe word. Priming effects were observed, since probe reaction time to related probes was faster than that to unrelated probes. Ways in which this paradigm can be used to study various issues in language processing are discussed.     

Tier 1 and Tier 2 early intervention for handwriting and composing

Three studies evaluated Tier 1 early intervention for handwriting at a critical period for literacy development in first grade and one study evaluated Tier 2 early intervention in the critical period between third and fourth grades for composing on high stakes tests. The results contribute to knowledge of research-supported handwriting and composing instruction that informs practice as school psychologists are empowered to embrace the role of intervention specialist. The first study found that neurodevelopmental training (orthographic-free motor activities and motor-free orthographic activities) led to improved accuracy and legibility of letter formation, but that direct handwriting instruction with visual cues and verbal mediation led to improved automatic handwriting (rate of writing legible letters) and transfer to improved word reading. The second study found that neither motor training nor orthographic training alone added value to direct instruction in automatic letter writing and composing practice in developing handwriting skills, which transferred to improved word reading; but the added motor training did improve performance on a grapho-motor planning task for sequential finger movements that is relevant to composing. A related analysis showed that direct instruction with visual cues and memory delays may reduce reversals. A third study found that adding handwriting to reading instruction improved handwriting but did not add value to reading outcomes for at risk readers; reading instruction alone was beneficial for word reading, decoding, and comprehension. The fourth study showed that comprehensive, explicit instruction in the processes of composition led to more significant improvement, based on group and individual data, than did the regular fourth grade program, on high stakes writing assessment.

Examining dosage effects on prevention outcomes: Results from a multi-modal longitudinal preventive intervention for young disruptive boys

The present study examined (a) the predictive effect of disruptive boys' attendance to a prevention program (i.e., dosage) on post-intervention academic achievement and behavior and (b) the potential moderating effects of child and family characteristics in this context. The 3-year intervention program included reading, self-regulation, and social skills training for the boys, parental support and skills training for parents, and teacher support. A multiple-screening procedure selected 58 disruptive, low socioeconomic status boys at the age of 6 years for program participation. Multiple regression analyses and logistic regression analyses showed that the number of program sessions attended did not contribute to the prediction of boys' post-intervention disruptive behavior. However, the number of attended sessions was positively related to boys' post-intervention likability, as well as to their post-intervention writing, reading, math, and human science performances. Interaction terms revealed that family constellation moderated the link between program dosage and likability and math success, respectively, whereas boys' IQ moderated the links between dosage and boys' success in writing and math. The discussion stresses the importance of dosage-effect analysis and the examination of moderating variables in this context.     

Patterns of Natural Language Use: Disclosure, Personality, and Social Integration

When people write about their deepest thoughts and feelings about an emotionally significant event, numerous benefits in many domains (e.g., health, achievement, and well-being) result. As one step in understanding how writing achieves these effects, we have developed a computer program that provides a "fingerprint" of the words people use in writing or in natural settings. Analyses of text samples indicate that particular patterns of word use predict health and also reflect personality styles. We have also discovered that language use in the laboratory writing paradigm is associated with changes in social interactions and language use in the real world. The implications for using computer-based text analysis programs in the development of psychological theory are discussed.     

Self-esteem,belongingness, and worldview validation: Does belongingness exert a unique influence upon self-esteem?

The current work examined whether belongingness influences self-esteem independently from worldview validation (the extent to which one lives to beliefs that are shared by others). Questionnaire measures demonstrated that people with stronger social ties had higher self-esteem, and that worldview validation did not account for this relationship. Further, belongingness and worldview validation were manipulated such that they pulled self-esteem in opposing directions, yet belongingness still influenced self-esteem. Participants had higher self-esteem after writing about social acceptance than rejection even though acceptance was accompanied by either failing to live up to an important value or having one’s worldviews rejected. This latter effect was most pronounced among participants with high social anxiety. Results indicate that belongingness makes a unique contribution to self-esteem.     

Application of social skills training in a group of institutionalized aggressive elderly subjects

A social skills training program consisting of instructions, modeling, role playing, and feedback was carried out with a group of 6 verbally aggressive institutionalized elderly patients. Dependent measures included confirmed incidents of verbal aggressive behavior monitored across an ABAB design with a 5-month follow-up period. Results indicated that verbally aggressive behavior can be significantly decreased in a group-training setting and subsequently generalized to ward and other socialized behavior. Ancillary aspects of the study include the role of social reinforcement, participant modeling, and staff attitude, perception, and motivation. Implications for future research are discussed.     

Adapting to the surface: A comparison of handwriting measures when writing on a tablet computer and on paper

Our study addresses the following research questions: Are there differences between handwriting movements on paper and on a tablet computer? Can experienced writers, such as most adults, adapt their graphomotor execution during writing to a rather unfamiliar surface for instance a tablet computer?We examined the handwriting performance of adults in three tasks with different complexity: (a) graphomotor abilities, (b) visuomotor abilities and (c) handwriting. Each participant performed each task twice, once on paper and once on a tablet computer with a pen.We tested 25 participants by measuring their writing duration, in air time, number of pen lifts, writing velocity and number of inversions in velocity. The data were analyzed using linear mixed-effects modeling with repeated measures.Our results reveal differences between writing on paper and on a tablet computer which were partly task-dependent. Our findings also show that participants were able to adapt their graphomotor execution to the smoother surface of the tablet computer during the tasks.     

Promoting adaptive foot movements and reducing hand mouthing and eye poking in a boy with multiple disabilities through microswitch technology

This study assessed the viability of a microswitch cluster (i.e. a combination of microswitches) plus contingent stimulation for promoting adaptive responding and reducing aberrant behavior in a boy with profound multiple disabilities. The boy was initially taught an adaptive foot-movement response that activated a motion microswitch and produced preferred stimuli. Subsequently, his foot response led to preferred stimuli only if it occurred in the absence of aberrant behavior (i.e. hand mouthing and eye poking which were detected through optic microswitches). Moreover, full access to the stimuli required that the boy refrain from aberrant behavior during their presentation as well. The study also included a 3-month post-intervention check and a social validation assessment. Data showed that the boy (i) increased his adaptive responding, (ii) learned to perform this responding largely free from aberrant behavior and refrained from that behavior for most of the session time, and (iii) maintained this performance at the post-intervention check. The social validation ratings of 40 teachers and teacher assistants significantly favored the last intervention period (in which aberrant behavior was reduced) over the initial period.
