The increasing reliance on and advancement of technology requires an in-depth exploration into how users interact with mechanical and virtual devices. To explore how individuals categorize different technologies, we conducted a multidimensional scaling (MDS) study to analyze the perceived similarity or dissimilarity between technologies. In the exploratory study on 23 devices, we found items rated similarly based on two dimensions – technological sophistication and size. Technology categorization, specifically with the use of MDS, is an under investigated approach in human factors that, through further exploration, may yield a better understanding of users’ mental models and acceptance, with utility for both designers and researchers.

AIM: The aim of this exploratory study was to determine whether the level of nursing teamwork is correlated to call light answering time in acute care hospital patient care units. Background: Teamwork has been shown to improve productivity. In this study, we examine the relationship between unit call light response time as a measure of productivity and the level of teamwork on the unit. METHOD: The Nursing Teamwork Survey was administered to nursing staff on 18 inpatient units in 3 hospitals. In addition to the overall teamwork score, the NTS has 5 subscales. Call light response times were collected from electronic systems which measures the time it takes for nursing staff on a given unit to respond to patient call lights. RESULTS: There was no significant relationship between call light response time and teamwork overall or on the five subscales. Shared mental models, which comprise the conceptual understanding of the roles and responsibilities of each team member, however was moderately correlated with call-light answering times. CONCLUSIONS: It is logical that shared mental models would be associated with call light response time since a common problem in patient units is the "it's not my job syndrome" where nursing staff do not answer call lights for patients assigned to someone else. More research with a larger number of patient units is needed to validate these findings.

Purpose This exploratory study examined the language skills and the type and frequency of disfluencies in the spoken narrative production of Spanish–English bilingual children who do not stutter. Method A cross-sectional sample of 29 bilingual students (16 boys and 13 girls) enrolled in grades prekindergarten through Grade 4 produced a total of 58 narrative retell language samples in English and Spanish. Key outcome measures in each language included the percentage of normal (%ND) and stuttering-like (%SLD) disfluencies, percentage of words in mazes (%MzWds), number of total words, number of different words, and mean length of utterance in words. Results Cross-linguistic, pairwise comparisons revealed significant differences with medium effect sizes for %ND and %MzWds (both lower for English) as well as for number of different words (lower for Spanish). On average, the total percentage of mazed words was higher than 10% in both languages, a pattern driven primarily by %ND; %SLDs were below 1% in both languages. Multiple linear regression models for %ND and %SLD in each language indicated that %MzWds was the primary predictor across languages beyond other language measures and demographic variables. Conclusions The findings extend the evidence base with regard to the frequency and type of disfluencies that can be expected in bilingual children who do not stutter in grades prekindergarten to Grade 4. The data indicate that %MzWds and %ND can similarly index the normal disfluencies of bilingual children during narrative production. The potential clinical implications of the findings from this study are discussed.

Use Of Knowledge

Abstract. Planning interactions with the physical world requires knowledge about operations; in short, mental operators. Abstractness of content and directionality of access are two important properties to characterize the representational units of this kind of knowledge. Combining these properties allows four classes of knowledge units to be distinguished that can be found in the literature: (a) rules, (b) mental models or schemata, (c) instances, and (d) episodes or chunks. The influence of practicing alphabet-arithmetic operators in a prognostic, diagnostic, or retrognostic way (A + 2 = ?, A? = C, or ? + 2 = C, respectively) on the use of that knowledge in a subsequent test was used to assess the importance of these dimensions. At the beginning, the retrognostic use of knowledge was worse than the prognostic use, although identical operations were involved (A + 2 = ? vs. ? - 2 = A). This disadvantage was reduced with increased practice. Test performance was best if the task and the letter pairs were the same as in the acquisition phase. Overall, the findings support theories proposing multiple representational units of mental operators. The disadvantage for the retrognosis task was recovered in the test phase, and may be evidence for the importance of the order of events independent of the order of experience.
