Illusory Truth Effect

According to numerous research studies, when adults hear a statement twice, they are more likely to think it is true compared with when they have heard it only once. Multiple theoretical explanations exist for this illusory-truth effect. However, none of the current theories fully explains how or why people begin to use repetition as a cue for truth. In this preregistered study, we investigated those developmental origins in twenty-four 5-year-olds, twenty-four 10-year-olds, and 32 adults. If the link between repetition and truth is learned implicitly, then even 5-year-olds should show the effect. Alternatively, realizing this connection may require metacognition and intentional reflection, skills acquired later in development. Repetition increased truth judgments for all three age groups, and prior knowledge did not protect participants from the effects of repetition. These results suggest that the illusory-truth effect is a universal effect learned at a young age.

Illusory Truth Effect

Repetition increases belief in false statements. This illusory truth effect occurs with many different types of statements (e.g., trivia facts, news headlines, advertisements), and even occurs when the false statement contradicts participants’ prior knowledge. However, existing studies of the effect of prior knowledge on the illusory truth effect share a common flaw; they measure participants’ knowledge after the experimental manipulation and thus conditionalize responses on posttreatment variables. In the current study, we measure prior knowledge prior to the experimental manipulation and thus provide a cleaner measurement of the causal effect of repetition on belief. We again find that prior knowledge does not protect against the illusory truth effect. Repeated false statements were given higher truth ratings than novel statements, even when they contradicted participants’ prior knowledge.

Aim: Study was conducted to examine the different parameters of human thymus glands of young and old patients and compare the findings between both age groups. Study Design: Comparative/observational study Place and Study: Study was conducted at Anatomy department of Nishtar Medical University Hospital, Multan for duration of six months from 15th January 2020 to 15th July 2020. Methods: Total 54 specimens of human thymus of 54 patients were enrolled in this study. All specimens were divided in to two groups I and II, Group I contains 27 patients with ages <30 years and group II with 27 patients having ages 45 to 60 years. All specimens were fixed in 10% formalin solution and then processed for paraffin embedding. Compare the different parameters such as thickness of interlobular connective tissue and thymic capsule, length and number of Hassal’s corpuscles between both groups. Data was analyzed by SPSS 24.0. Results: In group I 12 (44.44%) patients were ages <15 years and 15 (55.56%) patients were ages >15 years. In group 13 (48.15%) and 14 (51.85%) patients were ages <50 years and >50 years. There was a significant difference observed between both groups regarding thickness of interlobular connective tissue and thymic capsule, quantity and length of Hassal’s corpuscles with p-value <0.05. Conclusion: It is to be concluded that patients with young age had significantly less thickness of thymic capsule and interlobular connective tissue with more in number and decreasing size of Hassal’s corpuscles as compared to old age patients.

Objective: The present study aimed to determine if the prevalence of pre-eruptive intracoronal radiolucent defects is higher for young age groups, in which there are more unerupted teeth. Study design: A retrospective study of panoramic and bitewing radiographs was conducted. An inclusion criterion was the presence of un-erupted permanent teeth with a formed and clearly visible crown. Age groups were: young (6–8 years), intermediate (9–12 years) and adults (13–53 years). Significance level was set at p≤0.05. Results: Thirteen (3.9%) pre-eruptive lesions were detected in 335 records. No lesions were found in the young group (7.4%), in the intermediate and adult age groups six and seven lesions were found, respectively. In most cases the pre-eruptive lesion was found in a third molar. Conclusion: The prevalence of pre-eruptive intracoronal lesions was not higher for young age groups. The prevalence of pre-eruptive intra coronal radiolucent lesions is 3.9%, irrespective of age.

The objective: to study changes in the structure of mortality from tuberculosis and HIV infection in Russia from 2000 to 2017.Subjects and methods. The data of the Federal State Statistics Service on the mortality of the Russian population from tuberculosis and HIV infection (standardized ratio per 100,000 population) for 2000-2017 were studied. Data on the structure of patients with TB/HIV co-infection were obtained from Form no. 61 of the federal statistical monitoring for 2017.Results. In Russia, there has been a steady decrease in the mortality rate from tuberculosis, the value of which in 2017 reached 5.9 per 100,000 people. At the same time, the average values of the mortality rate from tuberculosis have shifted towards the older age groups reaching maximum values in the age group of 45 years and older. On the contrary, the analysis of mortality from HIV infection (2006-2017) detected its unprecedented increase from 1.6 to 12.6 per 100,000 population. The maximum concentration of mortality from HIV infection was observed in young age groups (35-44 years old). The increase in mortality from HIV infection was accompanied by a change in the structure of mortality from infectious diseases: the proportion of tuberculosis decreased from 79.1% (2000) to 27.4% (2017), and the proportion of HIV infection increased from 0.1% ( 2000) to 57.2% (2017). Currently, in Russia, mortality from HIV infection in young age groups has taken a leading position in the structure of causes of death from infectious diseases, displacing mortality from tuberculosis.

For the benefit of a younger audience, the cherry can be further enhanced by freeing it from the fruit group and allowing it to become part of the world of desserts and special treats. On the contrary, the localisms, traditions, and seasonality which characterize much of the national production can be further emphasized for the middle age and the “differently young” age groups, especially for the domestic market. Common to these diverse strategies is the need for high performance varieties linked to a structured sales season and non-destructive sorting with the use of the latest technologies to guarantee what the English-speaking world calls “consistent quality” and what we could rename “quality that lives up to our promises.”
