Comparison of 'Mental training' and physical practice in the mediation of a structured facial examination : a quasi randomized, blinded and controlled study
Background: The correct performance of a structured facial examination presents a fundamental clinical skill to
detect facial pathologies. However, many students are not adequately prepared in this basic clinical skill. Many
argue that the traditional âSee One, Do Oneâ approach is not sufficient to fully master a clinical skill. âMental Trainingâ
has successfully been used to train psychomotor and technical skills in sports and other surgical fields, but its use in
Oral and Maxillofacial Surgery is not described. We conducted a quasi-experimental to determine if âMental Trainingâ
was effective in teaching a structured facial examination.
Methods: Sixty-seven students were randomly assigned to a âMental Trainingâ and âSee One, Do Oneâ group. Both
groups received standardized video instruction on how to perform a structured facial examination. The âSee One,
Do Oneâ group then received 60 min of guided physical practice while the âMental Trainingâ group actively
developed a detailed, stepwise sequence of the performance of a structured facial examination and visualized this
sequence subvocally before practicing the skill. Student performance was measured shortly after (T1) and five to 10
weeks (T2) after the training by two blinded examiners (E1 and E2) using a validated checklist.
Results: Groups did not differ in gender, age or in experience. The âMental Trainingâ group averaged significantly
more points in T1 (pE1 = 0.00012; pE2 = 0.004; dE1 = 0.86; dE2 = 0.66) and T2 (pE1 = 0.04; pE2 = 0.008, dE1 = 0.37;
dE2 = 0.64) than the âSee One, Do Oneâ group. The intragroup comparison showed a significant (pE1 = 0.0002;
pE2 = 0.06, dE1 = 1.07; dE2 = 0.50) increase in clinical examination skills in the âSee One, Do Oneâ group, while the
âMental Trainingâ group maintained an already high level of clinical examination skills between T1 and T2.
Discussion: âMental Trainingâ is an efficient tool to teach and maintain basic clinical skills. In this study âMental
Trainingâ was shown to be superior to the commonly used âSee One, Do Oneâ approach in learning how to perform
a structured facial examination and should therefore be considered more often to teach physical examination skills
The effect of context attractiveness on product attractiveness and product quality: the moderating role of product familiarity
The conditional enjoyment-enhancing effect of shipping box aesthetics
Online retailers increasingly use aesthetically appealing shipping boxes to deliver products to their customers. However, little is known about the potential effects of delivering products in aesthetically appealing shipping boxes on customer responses. This study applies the Affective Expectations Model to propose that the effect of shipping box aesthetics on customer responses depends on customers' expectations. Three experiments provide evidence that delivering products in aesthetically appealing shipping boxes can increase customers' loyalty intentions and that the effect is driven by enjoyment of the product delivery experience. The authors further find that the enjoyment-enhancing effect of shipping box aesthetics manifests when customers purchase products from a value online retailer, when they purchase functional products, and when the delivered product matches the description on the retailer's website. The effect diminishes when customers purchase products from a luxury online retailer and when they purchase hedonic products. The effect reverses when the delivered product does not match the description on the retailer's website. These findings contribute to the packaging, e-commerce, and customer experience literature and provide actionable implications for online retailers
The effect of context attractiveness on product attractiveness and product quality: the moderating role of product familiarity
Prior research has investigated a number of drivers of consumers perceived product attractiveness, such as a products shape and color. The context, in which a product is presented, has so far been largely neglected in examining consumers aesthetic appraisal of products. Drawing on social cognition theory, this research investigates how the attractiveness of the visual context (e.g., websites, advertisements) influences consumers perceptions of product attractiveness and product quality for familiar versus unfamiliar products. Results of two experimental studies show that consumers perceive unfamiliar products as more attractive and, consequently, of higher quality when products are placed in an attractive context than when they are placed in an unattractive context. No differences in consumers perceived product attractiveness and perceived product quality exist for familiar products. The findings extend our theoretical knowledge of product aesthetics and provide managers with insights into the effective communication of their offerings attractiveness.(VLID)455214
3Dâprinted patient individualised models vs cadaveric models in an undergraduate oral and maxillofacial surgery curriculum: comparison of student's perceptions
Background: Recent advances in 3D printing technology have enabled the emergence of new educational and clinical tools for medical professionals. This study provides an exemplary description of the fabrication of 3Dâprinted individualised patient models and assesses their educational value compared to cadaveric models in oral and maxillofacial surgery.
Methods: A singleâstage, controlled cohort study was conducted within the context of a curricular course. A patient's CT scan was segmented into a stereolithographic model and then printed using a fused filament 3D printer. These individualised patient models were implemented and compared against cadaveric models in a curricular oral surgery handsâon course. Students evaluated both models using a validated questionnaire. Additionally, a cost analysis for both models was carried out. Pâvalues were calculated using the MannâWhitney U test.
Results: Thirtyâeight fourthâyear dental students participated in the study. Overall, significant differences between the two models were found in the student assessment. Whilst the cadaveric models achieved better results in the haptic feedback of the soft tissue, the 3Dâprinted individualised patient models were regarded significantly more realistic with regard to the anatomical correctness, the degree of freedom of movement and the operative simulation. At 3.46 ⏠(compared to 6.51 âŹ), the 3Dâprinted patient individualised models were exceptionally costâefficient.
Conclusions: 3Dâprinted patient individualised models presented a realistic alternative to cadaveric models in the undergraduate training of operational skills in oral and maxillofacial surgery. Whilst the 3Dâprinted individualised patient models received positive feedback from students, some aspects of the model leave room for improvement
