Increase in physiological inhibitory control results in better suppression of unwanted memories

Forgetting or suppressing a memory with unwanted content is just as important as remembering a desirable one. In addition to emphasizing the role of inhibitory control in memory suppression processes, neuropsychological studies have indicated that an intentional inhibition targeting a brain area may exert its inhibitory effects in seemingly unrelated areas through a common inhibitory network. In this study, we aimed to investigate whether the suppression of unwanted memories can be strengthened by recruiting an inhibitory task that can be simultaneously performed with a memory suppression task. Therefore, we manipulated the level of urinary urgency-induced inhibition of participants (N = 180) and test its effect on the suppression of unwanted memories using a Think/No-Think (T/NT) task. The results of our study indicated that individuals with high levels of urinary urgency demonstrated greater memory suppression compared to those with low urinary urgency. Findings and their implications are discussed within the context of cognitive and clinical perspectives, and recommendations are made for future research.     

Unidirectional cycles of boredom,boredom coping strategies,and engagement among prospective teachers

This study examined the mediating roles of prospective teachers’ boredom coping strategies in the relationships between their levels of boredom and four aspects of engagement, and explored the unidirectional cycles of their levels of boredom, boredom coping strategies, and engagement. A total of 467 prospective teachers, majoring in primary school teaching, computer education and instructional technology teaching, mathematics teaching, English language teaching, special education teaching, and preschool teaching, voluntarily participated in the study. Structural equation modeling analyses were conducted to examine the reciprocal relationships between prospective teachers’ boredom, boredom coping strategies, and engagement. Results showed that the relationships between prospective teachers’ levels of boredom and cognitive engagement, emotional engagement, and behavioral engagement were significantly mediated by cognitive-approach strategies. Results also showed that the prospective teachers’ levels of boredom were reciprocally related to their emotional engagement through cognitive-approach strategies. Results suggest that the negative effects of boredom on cognitive engagement, emotional engagement, and behavioral engagement in the lessons can be significantly decreased by encouraging prospective teachers to adopt cognitive-approach strategies when they experience boredom. Results also suggest that prospective teachers may significantly decrease their levels of boredom not only by adopting cognitive-approach strategies, but also by increasing their emotional engagement during the lessons.     

A perception experiment with time-critical graphics animation on the World-Wide Web

The World-Wide Web offers a potentially interesting tool to collect data from a large and heterogeneous audience. While questionnaires have become rather common on the Internet, its potential reaches far beyond text processing. In principle, it is possible not only to perform interactive, dynamic experiments on the Web, but also to include graphical animation and time-critical responses, such as reaction times. We implemented a visual motion extrapolation task on the Web using the programming language Java, which can be interpreted by standard Web browsers such as Netscape or Internet Explorer. The data collected with this method turned out to be reliable and differed little from data obtained in a controlled laboratory setting, with the exception of conditions with fixation instruction. Thus, the Web can, generally speaking, be used for data collection of large sample sizes. The strengths and weaknesses of dynamic visual simulation experiments on the Internet are discussed.     

An automated technique for the study of cyclic fluctuations in sexual motivation in an avian species

Diurnal fluctuations in sexual behavior occur in freely interacting pairs of male and female birds. These fluctuations are difficult to interpret because they may reflect fluctuations in the motivation of the male, the motivation of the female, or both. A method was developed to study the sexual motivation of male Japanese quail in response to a standard stimulus. Sexual behavior was elicited by a taxidermic model of a female quail in a squatting posture. Sensors beneath and in the back of the model served to detect when the male mounted and made cloacal contact with the model. The technique allowed continuous recording of male sexual behavior under standard conditions. When males were maintained on a photoperiod with lights on at 0600 h and off at 2200 h, sexual behavior peaked in the early afternoon, with a secondary peak just before lights-out.     

Influences Between Online‐Exclusive,Conjoint and Offline‐Exclusive Friendship Networks: The Moderating Role of Shyness

Prior research has indicated that shy adolescents are more motivated to form friendships online than to form friendships offline. Little is known about whether having friendships found exclusively online may impact self‐esteem and forming offline friendships for these adolescents. This study therefore aimed to provide insight into the moderating role of shyness in the longitudinal interplay between friendships in online and offline contexts in early adolescence. Adolescents and their friends (193 girls, 196 boys; M_age = 13.29) were followed with three consecutive measurements with intervals of eight months. Results showed that particularly for shy adolescents, having friends exclusively online predicted increases in self‐esteem. Self‐esteem, in turn, was found to predict forming more friendships found both offline and online and forming more friendships found exclusively offline. Thus, findings supported the social compensation perspective that shy adolescents may benefit from having friends exclusively online, as these friendships may increase self‐esteem, thereby facilitating the formation of friendships found partially and completely offline.

Uncovering the links between prospective teachers’ personal responsibility,academic optimism,hope, and emotions about teaching: a mediation analysis

Prospective teachers’ sense of personal responsibility has not been examined together with their academic optimism, hope, and emotions about teaching in a single study to date. However, to consider hope, academic optimism, and emotions about teaching together with personal responsibility is important to uncover the factors affecting prospective teachers’ commitment to teaching. Indeed, this is an international concern that occupies educational researchers and policy makers from a diverse range of countries. Thus, this study aimed to examine the relationships between prospective teachers’ personal responsibility, academic optimism, hope, and emotions about teaching, with the intention to explore the mediating roles of hope and academic optimism in the relationships between emotions about teaching and personal responsibility. A total of 455 prospective teachers voluntarily participated in the study. Correlation, regression, and structural equation modeling analyses were conducted in order to explore the relationships between research variables. Results showed that the prospective teachers’ emotions about teaching, academic optimism, hope, and personal responsibility were significantly related to each other. Results also showed that the relationships between prospective teachers’ emotions about teaching and responsibility for student motivation, achievement, relationships with students, and teaching were strongly and positively mediated by their academic optimism; whereas the relationships between PTs’ emotions about teaching, responsibility for student achievement, and teaching were moderately and negatively mediated by their hope. Implications for teacher education and directions for future studies were also discussed in the present study.     

An analytic solution of initial boundary value problem for 3D quasicrystals in half space

In this article, initial boundary value problem for 3D quasicrystals in half space is considered. An analytic method is proposed for special form of initial conditions and nonhomogeneous term. It is explained that a weak solution of the problem can be constructed in the similar form of data by using symbolic calculations.     

The Determinants of Happiness in Turkey: Evidence from City-Level Data

This paper analyses the determinants of happiness in Turkey between 2004 and 2013 by relying on TURKSTAT’s Life Satisfaction Surveys. It contributes to the literature by employing a set of novel variables and a larger dataset which became representative at city-level in 2013. Some of the interesting findings are as follows: degree of hope is found to be the strongest estimator of happiness which was neglected in previous studies; job satisfaction is as important as being employed. Similarly, being married makes people happier only if they are satisfied from their marriage. Education brings more happiness only if it helps to increase income. Moreover, our results support Easterlin Paradox (Nations Househ Econ Growth Essays Honor Moses Abramovitz 1974. doi: 10.1016/B978-0-12-205050-3.50008-7). We have shown that happiness and income share a potent and positive relationship when yearly or pooled micro datasets are analysed, which has not been observed in macro data.
