Adolescents are susceptible to peer influence—in particular, “explicit peer influence” (EPI)—when making decisions. However, prior research has elicited mixed findings with respect to the exact effects of positive and negative EPI. Ensuring ecological validity regarding the present examination of different types of EPI, the Stoplight Game paradigm was revised by recording an adolescent in a simulated driving task in the presence of his or her classmate. A sample of 110 Chinese middle-school students (aged between 12 and 16 years old) was used to form 60 same-sex dyads that were randomly assigned to “negative EPI” (peer encourages driver to cross intersections as traffic light turns yellow), “positive EPI” (peer discourages such behaviors), and control (peer keeps quiet) conditions. The proportion of participants crossing intersections and the number of crashes were significantly higher in the negative EPI condition than in the control and positive EPI conditions. Latency with respect to crossing in the negative EPI condition was significantly longer than in the control group. These results suggest that negative EPI encourages adolescents to take risks, while positive EPI attenuates risky behavior. The effects of friendship status and gender were found to be insignificant. Further studies are warranted to elucidate the mechanisms underlying EPI.

Objective(s). The purpose of this study was to explore the effectiveness of wideband acoustic immittance (WAI) in the diagnosis of otosclerosis by comparing the differences in the energy reflectance (ER) of WAI between patients with otosclerosis and age- and gender-matched normal hearing controls in the Chinese population. Methods. Twenty surgically confirmed otosclerotic ears were included in the otosclerotic group. The ER of WAI at ambient and peak pressures, resonance frequency, and 226-Hz tympanogram were collected prior to surgery using a Titan hearing test platform (Interacoustics A/S, Middelfart, Denmark). All diagnoses of otosclerosis in the tested ear were confirmed by surgery after the measurements. Thirteen normal adults (26 ears) who were age- and gender-matched with the otosclerotic patients were included as the control group. Results. At peak pressure, the ERs of otosclerotic patients were higher than those of the control group for frequencies less than 4,000Hz and were lower for frequencies greater than 4,000Hz. In addition, within the analyzed frequencies, the differences observed at 2,520Hz was statistically significant (p<0.05/16=0.003, Bonferroni corrected). At ambient pressure, the differences observed at 1,260 and 6,350Hz were statistically significant (p<0.05/16=0.003, Bonferroni corrected). Although the differences between the otosclerotic and control groups exhibited similar trends to those in studies implemented in Caucasian populations, the norms in the present study in the control group were different from those in the Caucasian populations, suggesting racial differences in WAI test results. Regarding the middle ear resonance frequency, no significant difference was observed between the two groups (P>0.05). Conclusion. WAI can provide valuable information for the diagnosis of otosclerosis in the Chinese population. Norms and diagnostic criteria corresponding to the patient’s racial group are necessary to improve the efficiency of WAI in the diagnosis of otosclerosis.

This study was developed and conducted to test the effect of cognitive restructuring in the management of mathophobia (that is, Mathematics anxiety) among secondary school students in Khana Local Government Area of Rivers State, Nigeria. To guide the study, two research questions and two null hypotheses were formulated for testing at 0.05 level of significance. In executing the study, the pre-test, post-test, and control group experimental research design was adopted using a randomized sample of 120 SS2 students drawn from three public secondary schools only. The researchers developed an instrument titled “Mathematics Diagnostic Questionnaire” (MDQ) which was adequately assessed for validity and reliability and was used in collecting pre-test and post-test data for the cognitive restructuring and control groups. Data analysis was done using mean, and standard deviation for the research questions, while independent sample and paired sample t-test were used for the hypotheses. The result obtained showed that the cognitive restructuring was significantly effective in the management of mathophobia among secondary school students. There is a slight reduction in the effect of cognitive restructuring during follow-up; there is a statistical significant difference in the mathophobic level of students treated with cognitive restructuring and those in the control group. Based on the major findings, recommendations were made among which is that functional guidance and counselling centers be established at all educational levels and be manned by professional counsellors who are competent in cognitive restructuring techniques to assist those who have mathophobia and other maladaptive behaviours. Suggestions for further study were made.

AbstractBackground:The aim of this study was to determine the serum levels of kisspeptin and ghrelin (GAH), as well as the relationship of these two peptides with each other in premature thelarche (PT) and premature adrenarche (PA) cases and to investigate the possibility of using these peptides as markers in the differentiation of puberty disorders.Methods:A PT group aged 1–8 years (n = 40), a PA group aged 1–9 years (n = 23, female/male = 20/3) and control groups consistent with each of the previous groups in terms of age and gender were created for the study. Kisspeptin and ghrelin levels were measured with ELISA methods from blood samples drawn while fasting in the morning.Results:When the PT group was compared with the controls, the plasma kisspeptin levels of the cases were significantly higher than the control group (165.47 ± 15.45 pmol/L, 96.82 ± 12.33 pmol/L, p = 0.005, respectively). Kisspeptin levels in the PA group did not show a difference with the control group (121.36 ± 17.99 pmol/L, 95.52 ± 11.54 pmol/L, p = 0.249, respectively). No significant difference could be found when GAH levels in the PT and PA groups were compared with controls. No significant correlation was found between kisspeptin and GAH levels in the PT and PA groups.Conclusions:Our results indicate that kisspeptin plays an important role in the PT, but GAH is not associated with puberty disorders.

Abstract Hikikomori is a Japanese term for social withdrawal, ranging from complete inability to venture outdoors to preferring to stay inside. The prevalence of hikikomori is high, up to 1.2% of the Japanese population, but only few studies have examined its emergence in adolescents. Therefore, we sought to identify environmental and psycho-behavioral characteristics related to hikikomori during adolescence. Parents of middle school students who underwent psychiatric outpatient treatment for hikikomori (n = 20) and control group parents (n = 88) completed the Child Behavior Checklist to evaluate their child’s psycho-behavioral characteristics and novel scales to evaluate environmental characteristics and hikikomori severity. Scores for all eight Child Behavior Checklist subscales were significantly higher in the experimental group. Multiple regression analysis revealed that “anxious/depressed,” “somatic complaints,” “lack of communication between parents” and “overuse of the Internet” were significant predictors of hikikomori severity. These findings can help identify individuals who are at risk of developing hikikomori.

The study examined empirically the impact of systematic and unsystematic assessment of instructions, cognitive style and gender on knowledge of physics concepts among Senior Secondary Two (SS II) Students in Lagos Island Local Government Area of Lagos State, Nigeria. It made use of 120 secondary school two (SS II) students (72 males and 48 females) in a pretest-posttest non-randomized control group design in which treatment systematic assessment at two levels was crossed with two levels of cognitive style and gender. Data analysis involved analysis of covariance and graphical illustration as post-hoc measures. The results indicate that allowing systematic attributes of continuous assessment (CASS) to come into play in physics teaching has significant effect on remembering of physics concepts across all the students’ cognitive style-gender groupings. The results also indicate a significant gender-group (in support of females) in remembering of physics concepts. These results show the need for secondary school physics teachers to bring in systematic characteristic of CASS into the assessment of physics teaching. The teachers should also be more patient with male students since their knowledge of physics concepts is significantly lower than that of their female counterparts.

In this study, it was investigated that effect of games including physical activity on digital game addiction of 11-14 age group middle-school students. Along with the determination of digital game addiction, conducting applied experimental study is important regarding showing results of application with theoretical knowledge towards solving problem. Within this framework, it was thought that “games including physical activity” will be important tool for decreasing the level of digital game addiction. Experimental Design method was used in the study in which was adopted Quantitative Research model. When 11-14 age group students who addicted digital games consisted of the population of the study, the sample of the study consisted of 29 girls and 51 boys who have studied. In the study, personal information form and digital game addiction scale that was developed by the researcher were used as measurement tools. During data collection period, by accepting applied pre-test to students as criterion sample process, students who have high addiction level (total scale score is 49 and above) were detected and control (n = 40) and experimental (n = 40) groups were created with unbiased assignment method. After the 12-weeks period “games including physical activity” training, the data which was collected from the control and experimental groups by taking post-test data was evaluated with SPSS 20 packaged software. It was found that there was a significant difference between pre-test and post-test of both sub-dimensions and total addiction scores and post-test scores were lower than pre-test scores. It was shown that post-test addiction scores were significantly higher than pre-test addiction scores in control group. When investigating post-test addiction scores of control and experiment groups, it was shown that addiction level of experimental group significantly decrease comparing control group. It was determined that pre-test/post-test scores of experimental group students did not show significant differences in terms of gender, age, education level of mothers, education level of fathers, number of siblings. It was also found that pre-test/post-test addiction scores of experimental and control groups showed significant differences regarding playing digital game duration. When playing digital game duration decreased in experimental group, playing game duration increased in control group. Therefore, it was concluded that addiction levels of students who are digital game addict decreased because of interesting games including physical activity. As a result; physical moving games and sports can be said to be an important tool in dealing with digital game addiction. It can also be said that an important way to protect children from such addictions is to do sports.
