Due to methodological shortcomings, results from studies that investigated long-term effects of error correction on accuracy improvement are inconclusive.By trying to overcome some of these design related drawbacks (i.e. the lack of a proper control group and time-on task differences between treatment groups), the present study intends to make a contribution to the ongoing error correction debate. The effectiveness of direct and indirect corrective feedback was compared to the effect of two control treatments: a treatment that offered students an extra opportunity to practice their writing skills, and a treatment in which students self-corrected their errors without any available feedback. Results show that corrective feedback can be effective in improving students’ accuracy: while short-term effects were found for both direct and indirect corrective feedback, only direct feedback proved to have a significant long-term effect. Neither of the control treatments had a significant effect on students’ accuracy.

Academic Field

The question if second language learners can benefit from corrective feedback has been a fiercely debated topic in the academic field for over a decade. Until now, research outcomes cannot settle this discussion since only short-term effectiveness of corrective feedback could be demonstrated. Due to methodological shortcomings, results from studies that investigated long-term effects of error correction on accuracy improvement are inconclusive. By trying to overcome some of these design related drawbacks, the present study intends to make a contribution to the ongoing error correction debate. The effectiveness of direct and indirect corrective feedback was compared to the effect of two control treatments: a treatment that offered students an extra opportunity to practice their writing skills, and a treatment in which students self-corrected their errors without any available feedback. Results show that corrective feedback can be effective in improving students' accuracy.

Abstract Native lamprey populations are declining worldwide. In the Pacific Northwest focus on conservation and management of these ecologically and culturally important species has increased. Concern has emerged regarding the effects of sampling and handling of lamprey, with little to no attention given to the larval lifestage. We monitored the survival of larval Pacific Lamprey Entosphenus tridentatus and Lampetra spp. after backpack electrofishing, deepwater electrofishing and suction-pumping, anesthesia, and handling. We performed survival trials on wild-caught lamprey (n = 15 larvae in each trial) collected from the Clackamas River drainage in Oregon, USA, coupled with control group trials from lamprey sourced from a hatchery (n = 10 larvae). Short-term (96 h) survival was >98% with only one observed mortality. Delayed mortality (1 wk) was observed for four individuals that had fungus; two of those were positive for the bacteria Aeromonas hyrdrophila. We recorded blood hematocrit as a secondary measure of stress. The baseline, nonstressed larvae hematocrit levels did not differ from those of fish that had undergone stress through electrofishing, suction-pumping, and handling without anesthesia. Electrofishing, suction-pumping, and anesthesia showed no short-term negative effects on larval lamprey although potential long-term effects remain unstudied. These techniques appear to provide efficient and relatively safe methods for collecting and surveying larval lamprey.

And Behavior

This study investigated the short-term effects of a workshop for 22 immediate supervisors designed to reduce musculoskeletal pain injuries. One group of supervisors received training on how to deal with musculoskeletal injuries, while the control group of 14 received no training. 36 male immediate supervisors and 171 male employees within the Swedish railroad system completed questionnaires before and after the intervention. The trained supervisors' ratings showed that they enjoyed the workshop and believed that it improved their skills. Moreover, trained supervisors significantly more often than the controls showed target behaviors and attitudes compatible with course content. Finally, employees of the trained supervisors reported significantly more often than the control group that their supervisor used target behaviors. It is concluded that an educational program for immediate supervisors is viable and may lead to changes in attitude and behavior. Teaching supervisors to work with employees is a rich field for future investigation; the long-term effects of such programs need to be studied.

Introduction: The ocular blood flow (OBF) is responsible for supplying nutrition to the retina, which plays a fundamental role in visual function. Massage is expected to improve the blood flow and, consequently, vascular function. The aim of this study was to determine the shortterm and long-term effects of periocular massage on OBF and visual acuity. Methods: The OBF and visual acuity were measured in 40 healthy adults aged 20–30 years before and after massage, and also in control subjects. Three massage methods were used: applying periocular acupressure (“Chinese eye exercise”: CE), using a facial massage roller (MR), and using an automated eye massager (AM). The OBF and visual acuity were first measured before and after applying each type of massage for 5 min. Eye massage was then applied for 5 min once daily over a 60-day period, while the control group received no massage. The same measurements were then performed again. Results: Performing short-term periocular massage showed significant interactions in time and massage effects on visual acuity in CE and AM groups, and on OBF in AM group, while 60-day massage period exerted no significant effects. No significant relationship was found between OBF and visual acuity changes. Conclusions: These results suggest that short-term periocular massage with Chinese eye exercise and automated eye massager can improve OBF and visual acuity, although no causal relationship was supported.

The purpose of this study was to determine the efficacy of auxiliary prescription labels in educating outpatients about medicines at two different time periods. Five hundred fifty-nine patients were randomly assigned either to an experimental group or a control group; each person in the experimental group received a prescription bottle to which one study auxiliary label (“sticker”) had been affixed, and those in the control group received bottles with no study sticker attached. Patients were interviewed by telephone approximately one week or two months after prescription pick up. Patients who had the study sticker affixed to their prescription bottle were significantly more knowledgeable after one week about precautionary information than those patients who did not receive stickers; however, sticker-group patients receiving the delayed interview incorrectly attributed many precautions to their medication. This is the first controlled study to document that auxiliary labels increase short-term knowledge about medications, and to suggest that the same labels may result in an inappropriate generalization over time.

The immediate and long-term effects of perceptual-motor training on kindergarten children (6 girls, 4 boys) were measured by the Gesell Copy Forms Test. A significant increase from the pretest to the first posttest was made by the experimental group but none by the control group ( ns = 5). The second posttest showed that these gains were relatively long-term rather than short-term.

BACKGROUND Mobile health (mHealth) interventions can increase physical activity (PA); however, their long-term impact is not well understood. OBJECTIVE The primary aim of this study is to understand the immediate and long-term effects of mHealth interventions on PA. The secondary aim is to explore potential effect moderators. METHODS We performed this study according to the Cochrane and PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines. We searched PubMed, the Cochrane Library, SCOPUS, and PsycINFO in July 2020. Eligible studies included randomized controlled trials of mHealth interventions targeting PA as a primary outcome in adults. Eligible outcome measures were walking, moderate-to-vigorous physical activity (MVPA), total physical activity (TPA), and energy expenditure. Where reported, we extracted data for 3 time points (ie, end of intervention, follow-up ≤6 months, and follow-up &gt;6 months). To explore effect moderators, we performed subgroup analyses by population, intervention design, and control group type. Results were summarized using random effects meta-analysis. Risk of bias was assessed using the Cochrane Collaboration tool. RESULTS Of the 2828 identified studies, 117 were included. These studies reported on 21,118 participants with a mean age of 52.03 (SD 14.14) years, of whom 58.99% (n=12,459) were female. mHealth interventions significantly increased PA across all the 4 outcome measures at the end of intervention (walking standardized mean difference [SMD] 0.46, 95% CI 0.36-0.55; <i>P</i>&lt;.001; MVPA SMD 0.28, 95% CI 0.21-0.35; <i>P</i>&lt;.001; TPA SMD 0.34, 95% CI 0.20-0.47; <i>P</i>&lt;.001; energy expenditure SMD 0.44, 95% CI 0.13-0.75; <i>P</i>=.01). Only 33 studies reported short-term follow-up measurements, and 8 studies reported long-term follow-up measurements in addition to end-of-intervention results. In the short term, effects were sustained for walking (SMD 0.26, 95% CI 0.09-0.42; <i>P</i>=.002), MVPA (SMD 0.20, 95% CI 0.05-0.35; <i>P</i>=.008), and TPA (SMD 0.53, 95% CI 0.13-0.93; <i>P</i>=.009). In the long term, effects were also sustained for walking (SMD 0.25, 95% CI 0.10-0.39; <i>P</i>=.001) and MVPA (SMD 0.19, 95% CI 0.11-0.27; <i>P</i>&lt;.001). We found the study population to be an effect moderator, with higher effect scores in sick and at-risk populations. PA was increased both in scalable and nonscalable mHealth intervention designs and regardless of the control group type. The risk of bias was rated high in 80.3% (94/117) of the studies. Heterogeneity was significant, resulting in low to very low quality of evidence. CONCLUSIONS mHealth interventions can foster small to moderate increases in PA. The effects are maintained long term; however, the effect size decreases over time. The results encourage using mHealth interventions in at-risk and sick populations and support the use of scalable mHealth intervention designs to affordably reach large populations. However, given the low evidence quality, further methodologically rigorous studies are warranted to evaluate the long-term effects.

Background: There is evidence of the effectiveness of repeated exposure to odours on short-term olfactory function. The aim of this study was to assess the long-term effects of olfactory training. Methods: We conducted a prospective study of 111 patients with post-infectious olfactory dysfunction. Two groups of patients performed olfactory training for 16 and 56 weeks, respectively, and were compared with a control group. The training was performed twice daily using four odours (phenyl ethyl alcohol, eucalyptol, citronellal, eugenol). Olfactory testing was performed by means of the Sniffin Sticks test as a baseline assessment and then every 8 weeks for 56 weeks. Subjective ratings were performed using a visual analogue scale (0-100). Results: Both training groups presented significantly higher scores than the controls. The long-term group had better results than the short-term group. Short-term training patients sustained their improvement within the follow-up period. Subsets analysis showed that training patients mainly increased identification and discrimination. Subjective ratings were in accordance with the olfactory test results. Conclusion: Long-term olfactory training seems to be associated with better results in patients with post-infectious olfactory loss than a short-term scheme. Short-term training provides sustainable results at 56 weeks follow-up assessment.

Rival Models

The argument that personal economic expectations drive support for British governing parties has received wide attention. This article employs aggregate data for the 1979–92 period to assess the effects of personal expectations, other subjective economic variables and evaluations of prime ministerial performance in rival party-support models. Analyses of competing models, including error correction specifications that take into account nonstationarity in the time series of interest, indicate that the personal expectations variants generally do very well, although they do not outperform one or more alternatives incorporating other types of economic evaluations. The error correction models show that the prime minister's approval ratings have significant short-term and long-term effects on governing party popularity.
