Adjusting speed to maintain fast and accurate performance is critical to goal-directed behavior. This study examined development of response time adjustments in the stop signal task in 13,709 individuals aged 6–17 years (49.0% Caucasian) across four trial types: correct and incorrect go, successful (stop-inhibit), and failed (stop-respond) trials. People sped more after correct than incorrect go responses and slowed more after failed than successful stop trials. Greater slowing after stop-respond but less slowing after stop-inhibit trials was associated with better response inhibition. Response time adjustments were evident in children as young as age 6, developed throughout childhood, and plateaued by age 10. Results were consistent with the predictions of the error detection and shifting goal priority hypotheses for adjustments.  相似文献

The structure and optimization of speechreading     

Arnold P 《Journal of deaf studies and deaf education》1997,2(4):199-211

Erber (1988) has claimed that one of the reasons for the ascendancy of hearing aids has been the loss of confidence in speechreading. Speechreading can be of value to those suffering from presbyacusis and other hearing disorders, in augmenting hearing aids and cochlear implants, for large numbers of people in developing countries who are unable to afford electronic aids, and for those in advanced countries who are reluctant to wear an aid. I discuss the structure and the optimization of speechreading. New methods to optimize natural speechreading skills are required that must be based on the structure and nature of speechreading. It has been suggested that speechreading is, to some extent, innate, and so 'hard-wired', which would mean that the effect of long-term training is limited. I critique this view and present a macro-analysis of the experimental literature. I suggest that the innate view may be somewhat overstated.  相似文献

Education on the appalachian trail: What 2,000 miles can teach us about learning     

Karen D. Arnold 《About Campus》2007,12(5):2-9

Rather than dwelling on why too many men don't succeed in college, trekker Karen Arnold examines the features of an experience in which many men do excel: the long hike from Georgia to Maine. Educators can learn why accomplishing this feat may be more rewarding than college.  相似文献   

Breaking the Cycle: Future Faculty Begin Teaching with Learner-Centered Strategies after Professional Development

The availability of reliable evidence for teaching practices after professional development is limited across science, technology, engineering, and mathematics disciplines, making the identification of professional development “best practices” and effective models for change difficult. We aimed to determine the extent to which postdoctoral fellows (i.e., future biology faculty) believed in and implemented evidence-based pedagogies after completion of a 2-yr professional development program, Faculty Institutes for Reforming Science Teaching (FIRST IV). Postdocs (PDs) attended a 2-yr training program during which they completed self-report assessments of their beliefs about teaching and gains in pedagogical knowledge and experience, and they provided copies of class assessments and video recordings of their teaching. The PDs reported greater use of learner-centered compared with teacher-centered strategies. These data were consistent with the results of expert reviews of teaching videos. The majority of PDs (86%) received video ratings that documented active engagement of students and implementation of learner-centered classrooms. Despite practice of higher-level cognition in class sessions, the items used by the PDs on their assessments of learning focused on lower-level cognitive skills. We attributed the high success of the FIRST IV program to our focus on inexperienced teachers, an iterative process of teaching practice and reflection, and development of and teaching a full course.  相似文献   

Smartphone-interfaced lab-on-a-chip devices for field-deployable enzyme-linked immunosorbent assay     

Arnold Chen  Royal Wang  Candace R. S. Bever  Siyuan Xing  Bruce D. Hammock  Tingrui Pan 《Biomicrofluidics》2014,8(6)

The emerging technologies on mobile-based diagnosis and bioanalytical detection have enabled powerful laboratory assays such as enzyme-linked immunosorbent assay (ELISA) to be conducted in field-use lab-on-a-chip devices. In this paper, we present a low-cost universal serial bus (USB)-interfaced mobile platform to perform microfluidic ELISA operations in detecting the presence and concentrations of BDE-47 (2,2′,4,4′-tetrabromodiphenyl ether), an environmental contaminant found in our food supply with adverse health impact. Our point-of-care diagnostic device utilizes flexible interdigitated carbon black electrodes to convert electric current into a microfluidic pump via gas bubble expansion during electrolytic reaction. The micropump receives power from a mobile phone and transports BDE-47 analytes through the microfluidic device conducting competitive ELISA. Using variable domain of heavy chain antibodies (commonly referred to as single domain antibodies or Nanobodies), the proposed device is sensitive for a BDE-47 concentration range of 10⁻³–10⁴μg/l, with a comparable performance to that uses a standard competitive ELISA protocol. It is anticipated that the potential impact in mobile detection of health and environmental contaminants will prove beneficial to our community and low-resource environments.  相似文献
