Neural correlates of mapping from phonology to orthography in children performing an auditory spelling task

Age-related differences (9- to 15-year-olds) in the neural correlates of mapping from phonology to orthography were examined with functional magnetic resonance imaging (fMRI). Participants were asked to determine if two spoken words had the same spelling for the rime (corresponding letters after the first consonant or consonant cluster). Some of the word pairs had conflicting orthography and phonology (e.g. jazz-has, pint-mint) whereas other pairs had non-conflicting information (e.g. press-list, gate-hate) (see Table 1). There were age-related increases in activation for lexical processing (across conflicting and non-conflicting conditions) in left inferior parietal lobule, suggesting that older children have a more elaborated system for mapping between phonology and orthography that includes connections at different grain sizes (e.g. phonemes, onset-rimes, syllables). In addition, we found that the conflicting conditions had lower accuracy, slower reaction time and greater activation in left inferior frontal gyrus as compared to non-conflicting conditions. Higher accuracy was also correlated with greater activation in left inferior frontal gyrus for the most difficult conflicting condition (e.g. jazz-has). The finding of both a conflict effect and a correlation with accuracy in left inferior frontal gyrus suggests that this region may be involved in resolving the conflict between orthographic and phonological representations.     

Professional Basketball's Unsportsmanlike Fouls in the Eyes of the Beholders

A series of three experiments, based on the method of Functional Measurement, has explored the importance assigned by professional basketball players to relevant dispositions of defense and offense players, as determinants of unsportsmanlike fouls. The 106 participants were leading male players in the premier basketball league in Israel. Experiment 1 was based on a 16 (2⁴)‐cell model. In an individual meeting, each participant estimated the likelihood that a defense player would commit an unsportsmanlike foul on an offense player. In each of the 16 to‐be‐judged incidents, specific information on a specific combination of aggressiveness and susceptibility to victimisation of two imaginary protagonists in an offense–defense on‐the‐court incident was given to the participant. Experiment 2 was a replication of Experiment 1. There, however, names of 16 well‐known players were mentioned, the aggressiveness and susceptibility to victimisation of each fitting the model requirements. In Experiment 3, a partial replication of Experiment 2, likelihood estimations were made from two perspectives—potential perpetrator and potential victim. Overall, meaningful importance was assigned especially to the dispositions of the perpetrator, not the victim. The findings are conceived as reflections of players' cognitive schemata of on‐the‐court violence. Basée sur la méthode de la mesure fonctionnelle, une série de 3 expérimentations a exploré l’importance que des joueurs de basket professionnels attribuent aux dispositions de joueurs attaquant ou défenseur à commettre des fautes anti sportives. Les 106 sujets sont des joueurs de sexe masculin de la ligue 1 de basket israélienne. L'expérience 1 est basée sur un modèle à 16 (2⁴) cases. Lors de passation individuelle, chaque participant estime la probabilité qu'un joueur arrière commette une faute anti sportive sur un joueur avant. Pour chacun des 16 incidents à juger, une information spécifique a été donnée aux participants. Il s'agissait d'une combinaison particulière de l'agressivité et de la propension à la victimisation des deux protagonistes imaginaires dans une situation d'incident soit offensif soit défensif sur le terrain. L'expérimentation 2 est une réplique de la première. Cependant, les noms de 16 joueurs connus sont mentionnés, l'agressivité et la propension à la victimisation étaient appropriées aux exigences du modèle. Dans l'expérience 3, réplique partielle de la deuxième, la probabilité des estimations a été faite selon deux perspectives: auteur potentiel et victime potentielle. Globalement, une importance significative a été assignée aux dispositions de l'auteur et non de la victime. Les résultats sont conçus comme reflétant le schéma cognitif des joueurs lors de violence sur le terrain.     

An Anatomy of Political Beliefs: A Study of Their Centrality, Confidence, Contents, and Epistemic Authority

The present study is a simultaneous investigation of the contents of political beliefs and their characteristics among Israeli students. In addition, it examines their perceived use of information sources. The results indicate that political beliefs regarding the Israeli-Arab conflicts are organized systematically around the dove/hawk dimension. Also, a positive relationship was found between centrality of beliefs and confidence in them; between well-defined political identification and centrality and confidence; and between agreement with the beliefs and confidence. Finally, the results show that the perceived use of information sources is related to political identification. The performed investigation demonstrates the importance of combining the study of the contents of beliefs with that of their characteristics, since the latter have important implications for understanding individuals' cognitive, affective, and behavioral reactions.     

Prediction of Preschool Aggression from DRD4 Risk,Parental ADHD Symptoms,and Home Chaos

This study investigated the influence of a child’s DRD4 risk, parental levels of ADHD symptoms, and the interactive influence of these factors on the development of preschool aggression. Additionally, the study investigated the role of home chaos as a mediator between parental ADHD symptoms and child aggression. The sample consisted of 84 4.5-year-old children and their parents. Children were genotyped for the DRD4 polymorphism. ADHD symptoms were self-reported by parents when the child was 2 to 6 months old. Parental reports of home chaos and the child’s aggression were collected 4 years later. Child’s DRD4 risk and parental ADHD symptoms significantly contributed to the prediction of preschool aggression. However, contrary to our hypotheses, no interactions were found between the child’s DRD4 risk and the levels of parental ADHD symptoms. Home chaos played a mediating role in the relation between paternal ADHD symptoms and the child’s aggression. The relation between maternal ADHD symptoms and the child’s aggression was not significantly mediated through the level of home chaos. The current study emphasizes the importance of longitudinally investigating the contribution of parental ADHD symptoms to child aggression, while also exploring the differential contribution of maternal/paternal inattention and hyperactivity-impulsivity symptoms. Moreover, home chaos was found to be a significant environmental mechanism through which paternal ADHD symptoms affect children’s aggression in the preschool years.     

Presence of meaning,search for meaning,religiousness, satisfaction with life and depressive symptoms among a diverse Israeli sample

The present study explored the structure and correlates of meaning in life (MIL) among an Israeli sample. The sample consisted of 559 adults. The average age of participants was 48.24 and 61.3% of them were females. Participants provided demographic information and completed measures of MIL, satisfaction with life, and depressive symptoms. The MIL Questionnaire showed a very good fit for the proposed 2-factor model (i.e. presence of meaning, search for meaning) to the data collected from the current sample. Presence of meaning correlated positively with both search for meaning and satisfaction with life, and negatively with depressive symptoms. Search for meaning was positively and weakly tied to satisfaction with life, but was unrelated to depressive symptoms. Religiousness appeared as a significant moderator between the two meaning factors, and between them and life satisfaction. Specifically, as religiousness became stronger: (a) the link between presence of meaning and search for meaning became weaker; (b) the link between presence of meaning and life satisfaction became stronger and (c) the link between search for meaning and life satisfaction became weaker. The findings suggest that there are differential implications of presence search for meaning on the health and well-being, and the important role religiousness plays in this regard.     

Comparative judgments of symbolic and non-symbolic stimuli yield different patterns of reaction times

Are different magnitudes, such as Arabic numerals, length and area, processed by the same system? Answering this question can shed light on the building blocks of our mathematical abilities. A shared representation theory suggested that discriminability of all magnitudes complies with Weber's law. The current work examined this suggestion. We employed comparative judgment tasks to investigate different types of comparisons — conceptual comparison of numbers, physical comparison of numbers and physical comparison of different shapes. We used 8 different size ratios and plotted reaction time as a function of these ratios. Our findings suggest that the relationship between discriminability and size ratio is not always linear, as previously suggested; rather, it is modulated by the type of comparison and the type of stimuli. Hence, we suggest that the representation of magnitude is not as rigid as previously suggested; it changes as a function of task demands and familiarity with the compared stimuli.     

The Role of Career Aspiration,Self-Esteem,Body Esteem,and Gender in Predicting Sense of Well-being Among Emerging Adults

During emerging adulthood, one’s sense of well-being undergoes many rapid changes. Although emerging adults often present considerable energy, creativity, and hopefulness, both in higher education classrooms and workplaces, they often experience a decrease in well-being due to experience confusion, stress encounters, and difficulties in transitioning to adulthood. The authors examined four noteworthy key socioemotional factors that may be linked to emerging adults' sense of well-being: career aspiration, self-esteem, body esteem, and gender. Three hundred 20- to 29-year-old university students participated in the study. Results showed that well-being was correlated positively with self-esteem and body esteem, and body esteem was correlated negatively with gender (men scored higher). Regression analyses revealed that for both men and women, self-esteem and body esteem predicted well-being. Nevertheless, when the gender was analyzed separately, career aspiration predicted well-being only for men, whereas body esteem predicted well-being only for women. The study findings illuminates the importance of generating preventive measures in childhood and adolescence, through reinforcing skills such as resilience and self-esteem with the aim of passing through emerging adulthood with as little harm as possible to the sense of well-being.     

Enhanced left frontal involvement during novel metaphor comprehension in schizophrenia: Evidence from functional neuroimaging

The neural basis involved in novel metaphor comprehension in schizophrenia is relatively unknown. Fourteen people with schizophrenia and fourteen controls were scanned while they silently read novel metaphors, conventional metaphors, literal expressions, and meaningless word-pairs. People with schizophrenia showed reduced comprehension of both novel and conventional metaphors. Furthermore, while controls showed enhanced brain activation in right inferior frontal gyrus (IFG) for novel metaphors versus meaningless word-pairs, people with schizophrenia showed an over-activation of left IFG and middle frontal gyrus (MFG). Direct comparison between the groups revealed greater activation in left precuneus for both novel metaphors and literal expressions vs. baseline for individuals with schizophrenia. Direct comparison for novel metaphors vs. literal expressions also revealed increased activation for individuals with schizophrenia in left MFG. These results suggest that the inefficient processing of novel metaphors in schizophrenia involves compensatory recruitment of additional brain regions that include the left MFG and left precuneus.     

Cyberbullying Victimization in Adolescents as Related to Body Esteem,Social Support,and Social Self-Efficacy

ABSTRACT

The authors examined cyberbullying victimization in the context of issues of key importance to youth: body esteem, social support, and social self-efficacy. Research has found that traditional peer-bullying victimization is significantly correlated with low body esteem in Western societies, especially pertaining to weight (R. Puhl & J. Luedicke, 2012 Puhl, R., & Luedicke, J. (2012). Weight-based victimization among adolescents in the school setting: Emotional reactions and coping behaviors. Journal of Youth & Adolescence, 41, 27–40. [Google Scholar]). Studies have also found a relationship among bullying victimization, appearance-related bullying, low body esteem, and psychosocial difficulties among youth (L. E. Park, R. M. Calogero, A.F. Young, & A. Diraddo, 2010 Park, L. E., Calogero, R. M., Young, A. F., & Diraddo, A. (2010). Appearance-Based Rejection Sensitivity predicts Body Dysmorphic Disorder symptoms and cosmetic surgery acceptance. Journal Of Social & Clinical Psychology, 29, 489–509. [Google Scholar]). However, the emergence of cyberbullying, characterized by its own special features (P. K. Smith et al., 2008 Smith, P. K., Mahdavi, J., Carvalho, M., Fisher, S., Russell, S., & Tippett, N. (2008). Cyberbullying: Its nature and impact in secondary school pupils. Journal of Child Psychology and Psychiatry, 49, 376–385. [Google Scholar]), has raised a salient need to explore the relationship between cyber victimization and body esteem, no less important with social framework, because both are key components in adolescents' lives that may be associated with cyberbullying victimization. The authors examined these relationships among 204 Israeli adolescents 14–16 years old. The results indicate a noteworthy prevalence (45%) of cyber victims. Cyber victimization is significantly correlated with low body esteem and low social support and social self-efficacy. Low body esteem and low social support predicted the probability of being a cyber victim. The results extend the knowledge about potential personal and social risk factors for cyber victimization during adolescence. Implications for specific intervention programs are discussed.
