Babble Noise

ObjectivesAuditory perceptual learning studies tend to focus on the nature of the target stimuli. However, features of the background noise can also have a significant impact on the amount of benefit that participants obtain from training. This study explores whether perceptual learning of speech in background babble noise generalizes to other, real-life environmental background noises (car and rain), and if the benefits are sustained over time.DesignNormal-hearing native English speakers were randomly assigned to a training (n = 12) or control group (n = 12). Both groups completed a pre- and post-test session in which they identified Bamford-Kowal-Bench (BKB) target words in babble, car, or rain noise. The training group completed speech-in-babble noise training on three consecutive days between the pre- and post-tests. A follow up session was conducted between 8 and 18 weeks after the post-test session (training group: n = 9; control group: n = 7).ResultsParticipants who received training had significantly higher post-test word identification accuracy than control participants for all three types of noise, although benefits were greatest for the babble noise condition and weaker for the car- and rain-noise conditions. Both training and control groups maintained their pre- to post-test improvement over a period of several weeks for speech in babble noise, but returned to pre-test accuracy for speech in car and rain noise.ConclusionThe findings show that training benefits can show some generalization from speech-in-babble noise to speech in other types of environmental noise. Both groups sustained their learning over a period of several weeks for speech-in-babble noise. As the control group received equal exposure to all three noise types, the sustained learning with babble noise, but not other noises, implies that a structural feature of babble noise was conducive to the sustained improvement. These findings emphasize the importance of considering the background noise as well as the target stimuli in auditory perceptual learning studies.

The purpose of this study was to determine if six weeks of plyometric training can improve an athlete’s agility performance in silat olahraga. Protocol: Thirty-four (n=34) silat olahraga athletes (mean age 14 ± 3.22 years old), mean weights (42 ± 10.89 kg), mean heights (148 ± 8.79 cm) were selected as a subject for this study. All subjects were randomly divided into two groups (control and experimental group). Seventeen athletes (n=17) in experimental group performed conventional silat workout routine and plyometric training for 6-week for 2 sessions per week in 45 min to 1 hour while the control group (n=17) only performed conventional silat workout routine. All subjects participated in hexagon agility test. The subjects were required to attend the pre-test on a week before the intervention for pre-test session, mid-test on the third week of the intervention training, and post-test session on the end of intervention week. Repeated measure mixed between-within ANOVA was utilized to analyze the results. Results: End of the 6-week intervention, results revealed, agility performance were statistically changed across the times (p<0.05) in the experimental group. The plyometric training group had a quicker time and reduced time on the ground across the time for the hexagon agility test. The results of this study proved that plyometric training could be an effective training technique to improve the agility performance among silat olahraga athletes.

Background: The aim of this study was to examine the effectiveness of sexual skills training and communication skills training on the sexual attitudes of married women. The statistical population of the present study consisted of all married women aged 18 to 45 years old in Tabriz in 2014. Methods: The quasi-experimental research design consisted of three groups (pre-test and post-test) using a comparative method. Individuals were randomly placed into three groups with 15 individuals each: a sexual skills training group, a communication skills training group and a control group. All individuals were tested before starting the training sessions. The two experimental groups received educational interventions consisting of eight sessions of 60 to 90 minutes, while the control group did not receive any training. Following the training sessions, all groups completed a post-test. The Sexual Knowledge and Attitudes Scale (SKAS) was used to collect the data; covariance analysis (ANCOVA) was used to analyze the results. Results: Based on the analysis, the results of a consequential least significant difference (LSD) test indicated a significant difference between the communication skills training method and the sexual skills training method in their roles in affecting women’s sexual attitudes positively. The P value for the communication skills group was 0.014 and 0.914 for the sexual skills group, indicating the communication skills training method was more effective. Differences are considered statistically significant at P>0.05. Conclusions: Communication skills training can have a positive impact on sexual attitudes and may be a preferred training option to reduce couples’ sexual problems.

Background: Functional ankle instability (FAI) is a common consequence of ankle sprain injury, especially in high-impact sports. Objectives: To investigate the effect of six weeks of suspension training with total resistance exercises (TRX) on proprioception and muscle strength in female athletes with FAI. Methods: Thirty female athletes with FAI (age: 21.9 ± 2.2 years, height: 169.3 ± 4.2 cm, and weight: 59.8 ± 6.1 kg) were randomly assigned to two equally numbered groups: TRX training and controls based on inclusion and exclusion criteria. In the pre-test, the anthropometric variables and also proprioception accuracy and muscle strength of subjects were evaluated by joint angle reset test (JART) and manual muscle testing (MMT) in both dorsiflexion and plantarflexion motions. The training group completed three sessions per week with progressive load for six weeks, and each training session lasted 15 - 20 minutes, whilst control subjects continued with their normal activity without special sport activities. After six weeks of training, all tests performed in the pre-test phase were also performed in the post-test phase. The t-test was used for statistic analysis (α ≤ 0.05). Results: The findings showed that TRX training significantly improved the proprioception accuracy (P ≤ 0.001) and muscle strength (P ≤ 0.001) in the training group rather than the control group. No statistically significant difference was found in any of the tests between pre-test and post-test for the control group (P > 0.05). Conclusions: Six weeks of TRX suspension training had a positive effect on strength and proprioception accuracy in female athletes with FAI.

Literacy Level

The aim of this study was to delve into the effect of context-based approach (CBA) over traditional instruction (TI) on students’ chemical literacy level related to thermochemical and thermodynamics concepts. Four eleventh-grade classes with 118 students in total taught by two teachers from a public high school in 2012 fall semester were enrolled in this particular study. The treatments were randomly assigned to the already formed classes; experimental groups were treated as CBA, the control groups as TI. Each teacher had one experimental and one control group. Open-ended contextual item sets were developed to assess students’ chemical literacy level in thermochemical and thermodynamics concepts. The test was administered to both groups as a post-test at the end of the implementation. Students’ responses to item sets were analyzed based on the rubric prepared as the answer key. Analysis of Covariance (ANCOVA) was used for interpreting the data. The results reveal that CBA is superior to TI on improving students’ chemical literacy levels, implying that CBA, as a discussion platform for concepts through real-life experiences, has a significant role in increasing students’ chemical literacy levels in abstract and difficult concepts regardless of the gender difference.

Speed And Accuracy

Differences between novices and experts in many piloting skills may be due to perceptual learning. Sufficient exposure to relevant stimulus variation produces more efficient information extraction, processing of higher-order patterns, and automaticity. Isolating and condensing relevant perceptual experience in part-task environments might accelerate training. Here we report initial studies of two prototype perceptual learning modules (PLMs) for flight training. Subjects were either experienced (500-2500 hour) civil aviators or non-pilots. In the Visual Navigation PLM, subjects received brief instruction on aeronautical chart symbology and then viewed 20-second segments of terrain (videotaped from aircraft). Each trial required a speeded, forced choice of the aircraft's location from three possible grid locations on the aeronautical chart. A separate control group received only 20 pre- and 20 post-test trials. In the Instrument Relationships PLM, subjects viewed displays of primary flight instruments and performed a speeded response classifying the flight attitude depicted. In both PLMs, subjects' speed and accuracy were measured over 9 blocks of trials. PLMs produced dramatic improvements in speed and accuracy for both non-pilots and pilots. Pilots initially outperformed non-pilots. Non-pilots after 1-2 hours of PLM training were as accurate and faster than pilots before training in both PLMs. The results suggest that PLMs have value for primary and recurrent training, both in aviation and other domains. Appropriately structured PLMs could condense perceptual learning processes that normally occur with extended experience. By fostering greater automaticity of pattern processing, PLMs might allow component skills to be more easily integrated in flight or other complex tasks.

Recently, the Whole Body Vibration (WBV) training has been introduced as an alternative method of exercise or as a type of physical exercise in health and fitness centers. The purpose of the present study was to examine the effect of Whole Body Vibration (WBV) training applied for 12 weeks on depression level. A total of 53 healthy young male individuals participated in this study. Volunteers were randomly divided into two groups as the Whole Body Vibration Training Group (n=27) and the Control Group (n=26). WBV group did training 3 times a week for 12 weeks. The Control Group did not do any trainings. The Beck Depression Inventory (BDI) was applied to both groups before and after the 12-week WBV training. When the Beck Depression Inventory (BDI) scores of the WBV training group and Control groups were compared, it was determined that there were no significant differences in the pre-test Beck Depression Inventory (BDI) scores of the WBVT and Control Group according to the Mann-Whitney U-Test.However, the post-test scores of the WBV training and Control groups was significant at a statistical level (p=.013). According to the Wilcoxon Signed Ranks test, the difference between the pre- and post-test scores of the WBV training group was significant at a statistical level (p=.014); and the difference between the pre-test and post-test scores of the Control Group was not statistically significant (p=.596). The effect of the Whole Body Vibration training on depression is positive and decreases the depression level.

The Impact

A quasi‐experimental matched pre‐test, post‐test control group design was used to investigate the impact of individual student focussed teacher inservice on the progress of students with disabilities enrolled in mainstream kindergarten classes. Twelve student pairs in one district of the NSW Department of Education and Training were matched on pre‐test scores collected at the end of the term prior to kindergarten entry. The kindergarten teachers of each student pair were assigned to a training and non‐training group. Teachers in the training group were involved in a 2 day inservice training program which focussed on the assessed needs of the students with disabilities in their classes. Teachers in both groups were surveyed to gauge their perceptions of the support they received in the identified students’ transitions to school and of their efforts to include the students. The students were reassessed at the end of kindergarten. Although the students as a whole made gains in all areas assessed, there were no statistically significant differences in the post‐test scores of the students in the classes of the teachers in the training versus the non‐training group. The implications of these findings and the results of the teacher survey are discussed.
