Scientific Phenomena

Drawings can serve as a useful tool for analyzing children’s understanding of scientific phenomena. This study examined children’s understandings about internal structure of the snail. Children from kindergarten at age 5 and from primary school of age 7 and 10, were asked to draw their concept about the internal structure of the snail. The results demonstrate the alternative conceptions held by the children. Analysis showed some significant differences in interpretation between both age groups and gender. Age related differences were in understanding of nervous, circulatory, muscle and digestive system, and such features as food, bones and mucus. Gender differences were not so significant at present studies. There were only few statistically significant observations concerning gender, that boys more often than girls consider mucus and other organisms (such as bacteria) as a part of snail internal structure. The girls drew more in the category food (7 years old) and bones (10 years old). The results also revealed ideas which made sense to the learner, but are not biologically accurate, such as organs located in the foot. Key words: alternative conceptions, drawings, invertebrates, mental models, snails.

Gender- and age-related differences in the variability of various human attributes and abilities have been investigated. This article investigates the age and gender differences in the variability of Holland’s six vocational dimensions with a sample including 1,519 participants, divided into four age groups: early adolescence (12–15 years old), adolescence (16–20 years old), young adulthood (21–30 years old), and adulthood (31–59 years old). The results showed nontrivial differences in the variability of vocational interests across gender and age groups alike. Although significant differences in variability were observed for all vocational interest dimensions except investigative, the most pronounced differences in variability across age and gender were observed for realistic and conventional dimensions. Generally, the observed differences in variability were larger in adolescence than in adulthood. Overall, vocational interests displayed less differentiation within the younger age groups (early adolescence and early adulthood) as compared to adulthood.

Describes a complex of methods for the implementation of scientific research, the information of those who were researched is represented, methodology and methods of the research are described.Covers a wide range of problems, in particular a comprehensive study of motivation for both physical activity (needs, interests, self-conception, performance, leisure and factors of a healthy lifestyle), and for learning and succeeding.Objective: to study gender peculiarities and differences in self-description of physical development of schoolchildren. Material: The study involved schoolchildren of 5-11 grades (n = 638), among them: young men - 282, girls - 386. Correlation analysis of self-description of subjective indexes of physical development of schoolchildren has been conducted. Results: Using the results of the testing “Self-description of physical development”. It was found out that the correlational connection of indicators of self-description of the physical development of respondents of all ages have certain gender differences. We found that general self-esteem of boys of primary school age is affected by more indicators than of the girls. Young men associate with their own self-esteem and physical qualities: coordination and flexibility. Girls associate their health with physical activity and their own physical abilities. Conclusions: The obtained results of the scientific experiment give us the right to assert the existence of age and gender differences between the indicators of self-description of boys and girls who are engaged in and not engaged in sports. The study of self-assessment of physical boys and girls of different ages helped to draw conclusions about common and different priorities of the motivational sphere of physical culture and sports in gender and age.

To establish the age- and sex-related normative values of sagittal alignment in asymptomatic Chinese adults, and to investigate the changes and possible associated compensation mechanisms across age groups. 584 asymptomatic Chinese adults aged 20–89 years were recruited. Subjects were grouped according to age and gender. Whole-body standing radiographs were acquired for evaluating sagittal alignment from spine to lower limb. Sagittal parameters between gender in different age groups were compared via independent t test. Pearson correlation analysis was used to demonstrate relationships between parameters. Thoracic kyphosis (TK) increased steadily while lumbar lordosis decreased gradually in both genders. Pelvic tilt (PT) in male is greater than in female across all age groups with age related gradual increase. There were significant differences between male and female from 20s to 60s in terms of knee flexion angle (KA) and ankle dorsiflexion angle (AA), but the differences were not significant after 60s. T1 pelvic angle (TPA) was significantly correlated with spinal, pelvic and lower-limb alignment. The older group (≥50 years) had a stronger correlation of TPA with PT and KA, whereas the younger (<50 years) had stronger correlation with TK. This study comprehensively presented the normative sagittal alignment based on a large asymptomatic population, which could serve as an age- and gender-specific reference value for spine surgeons when planning for correction surgery. Age can influence the recruitment of compensation mechanism that involve more pelvic and lower limb mechanisms for elderly people.

This study examined if imagery ability (i.e., vividness and temporal congruence between imagined and executed knee extensions) and imagery perspective preference were affected by ageing and gender. Ninety-four participants, 31 young, 43 intermediate, and 20 older adults completed the Vividness of Movement Imagery Questionnaire-2 and a knee extension temporal congruence test to reflect on their imagery ability and an imagery perspective preference test. Male participants had a better imagery ability than the female participants (F 4,85=2.84, p=.029, η2=.118). However, significant age-related changes in imagery ability were not found in the three age groups. Change in imagery perspective preference with a trend towards an external imagery perspective was observed with ageing (F 3,89=3.16, p=.028, η2=.096) but not between male and female. The results suggest that imagery ability may be preserved with ageing. As individuals age, their preference for using an imagery perspective shifts from a more internal to a more external perspective. This understanding is important when designing future imagery research and real-life application or clinical intervention.

Background: Upper lip appearance received major attention with the introduction of diverse treatment modalities, including lip augmentation, rhinoplasty surgery, and dental treatment designed to support the upper lip. Our objectives were to define the prevalence and characteristics of the upper lip horizontal line (ULHL), which is a dynamic line appearing during a smile, in relation to gender, malocclusions, aging, and facial morphology. Methods: First, the prevalence and gender distribution of ULHL was examined from standardized en-face imaging at full smile of 643 randomly selected patients. Second, cephalometric and dental cast model analyses were made for 97 consecutive patients divided into three age groups. Results: ULHL appears in 13.8% of the population examined, and prevailed significantly more in females (78%). The prevalence of ULHL was not related to age nor to malocclusion. Patients presenting ULHL showed shorter upper lip and deeper lip sulcus. The skeletal pattern showed longer mid-face, shorter lower facial height and greater prevalence of a gummy smile. Conclusions: Female patients with short upper lip, concavity of the upper lip, and gummy smile are more likely to exhibit ULHL. The ULHL is not age-related and can be identified in children and young adults. Therefore, it should be considered when selecting diverse treatment modalities involving the upper lip.

Survey Responses

A frequently reported finding in age-related sensory impairment is that olfaction shows consistent and uniform decline with age. In most studies, discerning whether loss in olfaction is due to aging per se or to factors extrinsic to the aging process (e.g., smoking, chemical exposure, head injury) is difficult. Moreover, studies of olfaction have generally relied on data collected from samples drawn primarily from Western societies. As such, little is known regarding differences in olfaction involving non-Western cultures. Using international data from the 1986 National Geographic Smell Survey, responses of 19,219 American respondents and 3,204 respondents from Africa were analyzed. All respondents were screened for factors negatively affecting olfaction. Measures of olfactory acuity included odor detection, identification, intensity, and quality. The odor of interest was androstenone, a scent produced by bacteria on the human body and appearing in sweat. The results indicate that some measures of olfactory acuity tend to decline across age groups, but that this decline is less marked than reported in previous studies. The most important finding is that loss of olfaction is not consistent or uniform between geographic regions of America or Africa, between male vs. female respondents, or among the four measures of olfactory acuity. African respondents (both men and women) had significantly higher percentages of detection than did American respondents, women generally reported higher levels of olfactory functioning than did men, and some measures of olfaction were stable across age groups, or were higher among older respondents (e.g., odor identification).

Background: The buccally displaced canines (BDC) are more commonly encountered conditions in orthodontic clinics. It is a positional variation result of several factors such as retained deciduous canines, crowding, and lateral incisors anomalous. Aims: To determine the prevalence and gender differences of one-two-three-four buccally displaced canines in the area of Shah-Alam, Malaysia. Methods: A cross-sectional study of 399 subjects; was consist of two age groups; 208 subjects of school children aged 12 years and 191 subjects of adults aged 18-23 years were examined clinically to determine the prevalence of BDC. Statistical analysis: The data were statistically analyzed using SPSS version 16; a Chi-square test was performed to assess the gender differences. Results: No gender differences were found in the school-children group while in the adults group a significant gender difference was found regarding one and four canine displacements (P < 0.05). The prevalence of one-two-three canine displacement was higher significantly between the two groups (P < 0.05). However, the frequency of one canine displacement was higher significantly in adult females and girls (P < 0.05). The frequency of three canines displacement was approximately equal in both genders. Conclusion: The frequency of one canine displacement was higher significantly in females. However, the frequency of four canines displacement was higher significantly in males. These features may help in providing additional clinical signs in diagnosis and interception of such clinical situation. It will be effective in treatment plan procedure if canine displacement is detected early, help clinicians on the prevention of impaction possibility.

Scientific literature highlighted gender differences in spatial orientation. In particular, men and women differ in terms of the navigational processes they use in daily life. Scientific literature highlighted that women use analytical strategies while men tend to use holistic strategies. According to classical studies, males show a net advantage at least in the two categories of mental rotation and spatial perception. Subsequently, brain-imaging studies have shown a difference between males and females in the activity of brain regions involved in spatial cognition tasks. What we can say with certainty is that, given the complex nature of the subprocesses involved in what we call spatial cognition, the gender differences recorded by numerous scientific studies conducted in this field are closely related to specific measured abilities. The evidence that emerges with certainty from diverse studies is, however, that of a huge variety of strategies that differ according to sex, context, purpose to reach, education, age, and profession. In the study presented here, the gender and age-related tests show a significant sex-based difference perspective-taking tasks, but there is no gender-based difference in the mental rotation task.
