The Relationship

Identifying the relationship between characteristics of the individual perception of time and the personality trait of impulsivity is the problem this study is devoted to. The aim of the study is to analyze the relationships between the various components of impulsiveness as a personality trait and the characteristics of an individual minute (IM) taking into account age and gender in a sample of Ukrainian university students (62 participants aged 17-22; 11 of them are men). To assess the features of time perception, the IM method was used according to F. Halberg. As the characteristics of MI, we used the mean and standard deviation for three consecutive measurements of IM and the average error of subjective time relative to objective one in percent. Impulsivity was measured using the UPPS-P Impulsive Behavior Scale test in the Ukrainian adaptation, which reveals 5 indicators of impulsivity: negative urgency, positive urgency, lack of premeditation, lack of perseverance, and sensation seeking. For Ukrainian students, impulsivity indicators correspond to the average norms of the French sample. The mean IM is 61.3 seconds and it is in the range of 36-88 seconds, the standard deviation of 3 IM measurements is 8 seconds, the average error of the subjective time relatively to the objective one was 9%. An inverse relationship between the mean duration of IM and the impulsivity index “positive urgency” was revealed. A direct relationship between the variability of the IM, the average error of the IM in percent and the impulsivity index “lack of perseverance” was also revealed. There are no signifiant differences in the mean duration of IM between men and women. At the same time, women have a signifiantly higher variability in time estimation – the standard deviation of IM is signifiantly greater in them than in men. By the characteristics of the impulsiveness, women have a signifiantly higher indicator of positive urgency than men. Age-related differences in the features of perception of time and impulsivity were not found. It will be worth to study relations of IM with other personality peculiarities such as Big Five traits and temperament types. This would give us more insights about diagnostical usefulness of IM measurements as proxy between physiological and psychological conditions of people.

The mean and standard deviation over 24 h for 3 groups of animals - active, intermediate and inactive - in physical activity units were 10948 ± 3360, 2611 ± 1973 and 484 ± 316 respectively. The differences were significant ( P = 0·004), demonstrating the ability of the method to distinguish between groups that can be visibly differentiated. The small within-animal physical activity standard deviation (18·85 PAU) obtained in another group, suggests that it also yields reliable physical activity measurements for non-human primates. The monitoring device used can discriminate between individual nonhuman primate physical activity levels in a free-living environment and does not alter daily behaviour. This makes possible the study of the relationship between physical activity and atherosclerosis in nonhuman primates.

Abstract Background To determine the relationship between country-level prevalence of early childhood caries (ECC), malnutrition and anemia in infants and preschool children.Methods Matched country level ECC, malnutrition and anemia prevalence information were generated from databases covering the period from 2000 to 2017. Multivariate general linear models were developed to assess the relationship between outcome variables (prevalence of stunting, wasting, overweight, and anemia) and the explanatory variable (ECC prevalence) adjusted for Gross National Income per capita. The adjusted regression coefficients (B) and partial eta squared were computed.Results The mean (standard deviation (SD)) ECC prevalence for 0-2 year-olds was 23.8 (14.8)% and 57.3 (22.4)% for 3-5 year-olds. The mean (SD) prevalence of wasting was 6.3 (4.8)%, overweight was 7.2 (4.9)%, stunting was 24.3 (13.5)%, and anemia was 37.8 (18.1)%. For 0-2-year-olds, the strongest and only significant association observed was between the prevalence of ECC and overweight (η2= 0.21): one percent higher ECC prevalence was associated with 0.12% higher prevalence of overweight (B= 0.12, P= 0.03). In 3-5-year-olds, the strongest and only significant association was observed between the prevalence of ECC and anemia (η2= 0.08): one percent higher prevalence of ECC was associated with 0.14% lower prevalence of anemia (B= -0.14, P= 0.048).Conclusion There were age-related disparities in the relationship between country-level prevalence of ECC, malnutrition and anemia. The relationship between ECC and overweight may be due to intake of sugars. The relationship between ECC and anemia needs further investigations.

Despite the widespread belief that the subjective speed of the passage of time increases with age, empirical results are controversial. In this study, a combination of questionnaires was employed to assess subjective time perception by 499 subjects, ages 14 to 94 years. Pearson correlations and nonlinear regression analyses on a variety of questionnaires and the age of the participants show that the momentary perception of the passage of time and the retrospective judgment of past periods of time are a function of chronological age; however, small-to-moderate effects accounted for at most 10% of the variance. Results generally support the widespread perception that the passage of time speeds up with age. These results are discussed in the context of models of prospective and retrospective time judgment, but interpretations have to be treated with caution given methodological limitations.

AbstractThe purpose of this work was to study the relationship between self-focused attention and mindfulness in participants prone to hallucinations and others who were not. A sample of 318 healthy participants, students at the universities of Sevilla and Almería, was given the Launay-Slade Hallucinations Scale-revised (LSHS-R, Bentall & Slade, 1985). Based on this sample, two groups were formed: participants with high (n = 55) and low proneness (n = 28) to hallucinations. Participants with a score higher than a standard deviation from the mean in the LSHS-R were included in the high proneness group, participants with a score lower than a standard deviation from the mean in the LSHR-R were included in the second one. All participants were also given the Self-Absorption Scale (SAS, McKenzie & Hoyle, 2008) and the Southampton Mindfulness Questionnaire (SMQ, Chadwick et al., 2008). The results showed that participants with high hallucination proneness had significantly higher levels of public (t(80) = 6.81, p < .001) and private (t(77) = 7.39, p < .001) self-focused attention and lower levels of mindfulness (t(81) = -4.56, p < .001) than participants in the group with low hallucination proneness. A correlational analysis showed a negative association between self-focused attention (private and public) and mindfulness (r = -0.23, p < .001; r = -0.38, p < .001 respectively). Finally, mindfulness was found to partly mediate between self-focused attention and hallucination proneness. The importance of self-focused attention and mindfulness in understanding the etiology of hallucinations discussed and suggest some approaches to their treatment.

Purpose: This study aimed to assess driving capabilities in patients with exudative age-related macular degeneration (AMD) causing unilateral blindness or paracentral scotoma without vision deterioration. Methods: Of the 275 patients with AMD who responded to a questionnaire regarding car driving at Osaka University Hospital, we excluded 78 patients who answered that they had never driven. Finally, 197 patients were included (50 with bilateral and 142 with unilateral AMD). We investigated the relationship between the questionnaire findings and best-corrected visual acuity (BCVA). Results: The mean age was 74.8 ± 6.9 years, and the mean BCVA in the right and left eyes were 0.48 and 0.47, respectively. A negative correlation was observed between the proportion of patients who stopped driving due to AMD and the vision in the worse eye (p < 0.0001); however, 66% of participants were still driving. Regardless of the BCVA, 84% of them wished to continue driving. Concerning perceived dangerous situations, all patients reported an oversight of people or signals and night driving; further, patients with unilateral and bilateral vision deterioration reported vision narrowness and difficulty with discerning signal colours, respectively. Conclusion: Despite the associated danger, patients with AMD continued driving. Close attention should be paid to the driving activities among patients with AMD, even if they have passed the relevant driving tests.

Natural lighting is an important factor that affects the comfort of building users. Natural lighting in a room requires a window area of ​​at least 1/6 of the floor area. This study was conducted to obtain the distribution of Daylight Factor (DF) as a natural lighting factor during the day in the room, based on the shift in the position of the window on the wall. The distribution of lighting entering the depth of the room through window openings is a tool to compare the best window position in the spread of illumination with DF calculations based on Sky Component (SC). Shifting the window position will be analyzed by Standard Deviation (S) and Mean (μ) based on the DF distribution. Optimizations of the DF distribution on the window position shifts if it has the largest DF mean value and the smallest DF variant value. The results of the study in a simple room showed that the optimal DF distribution was at the window position in the middle and the mean value was 2.59%. The relationship of shifting window position and DF distribution can be useful for architects to determine the function of a room in architectural design.

The article is devoted to research features of verbal and nonverbal cognitive representations of time as a component of the cognitive model of time perception in elderly and senile age. The basis of the relationship to time is a cognitive model of time perception, consisting of the cognitive representation of time. Cognitive model of time involved in the process of shaping a person's entire picture of the world and understanding their place in it. The results of the study allow us to describe the specifics of the knowing and experiencing of time. Representation of time in elderly and senile are characterized by the description of the time through the prism of the life, units of measuring time, as well as metaphorical images describing the properties and rate of flow of time. Time, in later ages represented as a finite resource that is accompanied by a feeling of scarcity, time pressure and accelerated subjective time.

The origin of platelet density heterogeneity is in dispute. We examined whether this heterogeneity is age-related or whether platelets of differing density are initially produced from megakaryocytes. 75Se-methionine labels megakaryocyte protein and hence platelets produced after its intravenous injection. Rats were injected intravenously with 30 μCi of 75Se-methionine. On each of the succeeding 5 days blood was taken from groups of 5 rats following intravenous injection of Prostaglandin E1 (PGE1), and platelets isolated by velocity sedimentation into gradients of polyvinylpurrolidone coated colloidal silica (Percoll).The isolated platelets, which represented > 93% of the whole blood population and showed < .002% leukocyte contamination, were spun to equilibrium through continuous linear gradients of Percoll. Fractionation of these gradients yielded 15 density dependent platelet subpopulations, whose platelet count and density were measured.After three washes with cold isotonic saline containing PGE1, each fraction was also counted for platelet associated 75Se activity.The relationship of radioactivity to platelet count for each fraction for each day was measured by the mean index of concordance which was between 9.997 and 9.992 for days 1 to 5.On day 2, modal radioactivity and modal platelet counts were found at mean densities of 1.0674 g/ml and 1.0682 g/ml respectively.It is concluded that platelet density does not vary with platelet age.

Although several definitions exist, a personality trait can be defined as the average or expected value of personality-relevant behaviors. However, recent evidence suggests that, while trait questionnaires and aggregated momentary assessments of personality are highly related, they may also differ in meaningful ways. In this study, we examine the relationship between trait and mean state personality. Results indicate that these two assessment strategies, although highly related, do not show convergence (r = .39–.64) levels that would signify an equity of constructs. In line with this, these two assessment strategies show differential predictive utility. Although the pattern of this differential predictive utility suggests that measurement error may account for differences, the difference between trait and mean state personality predicts affect in a manner consistent with self-discrepancy theory. Thus, although these two constructs are highly related, the differences between trait and mean state personality are meaningful.
