Family Correlates of False Belief Understanding in Early Childhood: A Meta‐Analysis

This meta‐analysis seeks to integrate findings from 25 years of research on family correlates of young children's false belief understanding (FBU). Using data from 93 studies of 3‐ to 7‐year‐old children, we examined the correlations between FBU and four of the most widely studied family factors: parental socioeconomic status, number of siblings, parental mental‐state talk, and mind‐mindedness. FBU exhibited modest associations with each family variable and these associations held even when individual differences in verbal ability were taken into account. Moderator analyses revealed key child‐related factors (e.g., age, gender) as well as methodological factors that amplified or attenuated the relations between FBU and each family variable. Crucially, available longitudinal data highlight the importance of family factors in the development of FBU.     

Measuring and Predicting Individual Differences in Executive Functions at 14 Months: A Longitudinal Study

This study of 195 (108 boys) children seen twice during infancy (Time 1: 4.12 months; Time 2: 14.42 months) aimed to investigate the associations between and infant predictors of executive function (EF) at 14 months. Infants showed high levels of compliance with the EF tasks at 14 months. There was little evidence of cohesion among EF tasks but simple response inhibition was related to performance on two other EF tasks. Infant attention (but not parent-rated temperament) at 4 months predicted performance on two of the four EF tasks at 14 months. Results suggest that EF skills build on simpler component skills such as attention and response inhibition.     

Data logger device applicability for wheelchair tennis court movement

Assessment of movement logging devices is required to ensure suitability for the determination of court-movement variables during competitive sports performance and allow for practical recommendations to be made. Hence, the purpose was to examine wheelchair tennis speed profiles to assess data logger device applicability for court-movement quantification, with match play stratified by rank (HIGH, LOW), sex (male, female) and format (singles, doubles). Thirty-one wheelchair tennis players were monitored during competitive match play. Mixed sampling was employed (male = 23, female = 8). Friedman’s test with Wilcoxon signed-rank post hoc testing revealed a higher percentage of time below 2.5 m · s^?1 [<2.5 vs. ≥2.5 m · s^?1: 89.4 (5.0) vs. 1.2 (3.5)%, Z = ?4.860, P < 0.0005, r = 0.87] with the remaining time [9.0 (4.9%)] spent stationary. LOW-ranked players were stationary for longer than HIGH-ranked counterparts [12.6 (8.7) vs. 8.2 (5.1)%, U = 30.000, P = 0.011, r = 0.46] with more time at low propulsion speeds (<1.0 m · s^?1). HIGH-ranked and doubles players spent more time in higher speed zones than respective counterparts. Females spent more time in the 1.0–1.49 m · s^?1 zone (U = 48.000, P = 0.047, r = 0.36). Regardless of rank, sex or format, propulsion speeds during wheelchair tennis match play are consistent with data logger accuracy. Hence, data logging is appropriate for court-movement quantification.     

Spatiotemporal characteristics of serial CSs and their relation to search modes and response form

In four experiments, we examined how the spatiotemporal proximity to food of the two elements of a serial conditioned stimulus (CS) influenced the pattern of CS-directed versus food-site-directed behavior in rats. Experiment 1 showed that only temporal proximity affected responding when the serial CS consisted of two successive 4-sec presentations of either a spatially near or a spatially far lever (NN or FF). However, Experiment 2 showed that behavior depended markedly on whether rats received a near followed by a far lever (NF) or a far followed by a near lever (FN). Experiment 3 showed that the effects of Experiment 2 could be changed by increasing the duration of the second CS element, and Experiment 4 showed that these changes were not related to previous training. We concluded that behavior produced by the spatiotemporal qualities of the lever elements can be attributed to a mapping between the temporal qualities of the CS elements and an underlying sequence of search modes related to finding food.

Usāma Ibn Munqidh's Lubāb al-Ādāb (The Kernels of Refinement): Autobiographical and Historical Excerpts

Usāma ibn Munqidh (d. 584/1188) is best known for his “memoirs” entitled Kitāb al-i?ibār, which provides a personal and detailed window into the world of an aristocratic Syrian Muslim in the period of the Crusades. But scholars have almost completely ignored a lesser-known work by Usāma called Lubāb al-ādāb or The Kernels of Refinement. This anthology consists mostly of poetic excerpts relating to adab, the ideal conduct of the male courtier, but, scattered throughout, it also contains a handful of narrative anecdotes about Usāma and his times very much akin to the material found in his “memoirs”: tales of admirable behaviour, of encounters with the Franks, of Usāma's family, and the daily life of the elites of his day. This article presents these narrative extracts translated into English for the first time, with commentary, and with the intention that The Kernels of Refinement will attract the attention it deserves from both Arabists and non-Arabists.     

Global and regional cardiac function in lifelong endurance athletes with and without myocardial fibrosis

The aim of the present study was to compare cardiac structure as well as global and regional cardiac function in athletes with and without myocardial fibrosis (MF). Cardiac magnetic resonance imaging with late gadolinium enhancement was used to detect MF and global cardiac structure in nine lifelong veteran endurance athletes (58?±?5 years, 43?±?5 years of training). Transthoracic echocardiography using tissue-Doppler and myocardial strain imaging assessed global and regional (18 segments) longitudinal left ventricular function. MF was present in four athletes (range 1–8?g) and not present in five athletes. MF was located near the insertion points of the right ventricular free wall on the left ventricle in three athletes and in the epicardial lateral wall in one athlete. Athletes with MF demonstrated a larger end diastolic volume (205?±?24 vs 173?±?18?ml) and posterior wall thickness (11?±?1 vs 9?±?1?mm) compared to those without MF. The presence of MF did not mediate global tissue velocities or global longitudinal strain and strain rate; however, regional analysis of longitudinal strain demonstrated reduced function in some fibrotic regions. Furthermore, base to apex gradient was affected in three out of four athletes with MF. Lifelong veteran endurance athletes with MF demonstrate larger cardiac dimensions and normal global cardiac function. Fibrotic areas may demonstrate some co-localised regional cardiac dysfunction, evidenced by an affected cardiac strain and base to apex gradient. These data emphasize the heterogeneous phenotype of MF in athletes.     

Educational Policy on Emotional Intelligence: Does It Make Sense?

Educational policy on emotional intelligence appears to be based more on mass-media science journalism than on actual educational and psychological research. The first section of this article provides an overview of the research areas of emotional intelligence, social and emotional learning, and character education; it further examines how these areas became linked in the popular press. The second section examines the scientific evidence for whether emotional intelligence underpins social and emotional learning, how emotional intelligence relates to success, and whether it is central to character. We conclude that educational policy in this area has outpaced the science on which it is ostensibly based, and recommendations for the future are made.     

Mothers' Cognitive References to 2‐Year‐Olds Predict Theory of Mind at Ages 6 and 10

Mothers' mental‐state references predict individual differences in preschoolers' false‐belief (FB) understanding; less is known about the origins of corresponding variation in school‐age children. To address this gap, 105 children completed observations with their mothers at child ages 2 and 6, three FB tasks and a verbal comprehension test at age 3, and five FB tasks at age 6. Seventy‐seven of these children completed five Strange Stories at age 10. Individual differences in mothers' cognitive references at child age 2 predicted variation in children's FB understanding at age 6 and Strange Stories scores at age 10 (controlling for number of mothers' turns and children's mental‐state references, verbal comprehension and FB understanding at age 3, and mothers' cognitive references at child age 6).
