Five factors (gender, handedness, some aspects of general health, family history, and intelligence) that could assist speech-language pathologists in identification of children who stutter (CWS) in 42 CWS and 34 fluent control children (children who do not stutter [CWNS]) were investigated. The data reported here were obtained from assessments…

The development of the correspondence between real and imagined motor actions was investigated in 2 experiments. Experiment 1 evaluated whether children imagine body position judgments of fine motor actions in the same way as they perform them. Thirty-two 8-year-old children completed a task in which an object was presented in different…

This study investigated the psychometrics of a recently developed global rating measure of videotaped parent-infant interaction, the "Manchester Assessment of Caregiver-Infant Interaction" (MACI), in a normative sample. Inter-rater reliability, stability over time, and convergent and discriminant validity were tested. Six-minute play…

Grip strength is an important predictor of several health outcomes in the general older population. Grip strength assessment is feasible and reliable in older adults with intellectual disabilities (ID), which makes it a valuable measurement for application in this population. The purpose of this study was to investigate the effect of handedness on…

We investigated the effects of age on proactive and reactive cognitive control in a large population sample of 809 individuals, ranging in age between 5 and 97 years. For that purpose, we used an anticue paradigm, which required a consistent remapping of cue location and response hand: Left-sided cues required right-hand responses and vice versa.…

70 soccer players in Gaziantep amateur league voluntarily participated in this study, (average of their ages 19,17±1,34years, average of their heights 181,28±5,06 cm, average of their body weights 76,75±4,43 kg and average of their sports experiences 3,78±0,95 years) to analyze visual and auditory reaction times and aerobic capacities of amateur…

The ambidexterity theory of leadership for innovation proposes that leaders' opening and closing behaviors positively predict employees' exploration and exploitation behaviors, respectively. The interaction of exploration and exploitation behaviors, in turn, is assumed to influence employee innovative performance, such that innovative performance…

Creativity is the ability to come up with new and original solutions to problems. It is characterized along a dipole spectrum, with the opposing ends defined as convergent and divergent thinking. Previous studies have provided evidence that various cognitive functions and insight into non-verbal problems can be enhanced using non-invasive brain…

Handedness for acquiring objects was assessed monthly from 6 to 14 months in 328 infants (182 males). A group based trajectory model identified 3 latent groups with different developmental trajectories: those with an identifiable right preference (38%) or left preference (14%) and those without an identifiable preference (48%) but with a…

This article presents a simple theory according to which the left-right reversal of single digits by 5- and 6-year-old children is mainly due to the application of an implicit right-writing or -orienting rule. A number of nontrivial predictions can be drawn from this theory. First, left-oriented digits (1, 2, 3, 7, and 9) will be reversed more…

Purpose: The purpose of this study is to investigate the effects of healthy aging on the ability to suppress grammatically illicit antecedents during pronoun resolution. Method: In 2 reading-based acceptability-judgment experiments, younger and older speakers of German read sentences containing an object pronoun and 2 potential antecedent noun…

Purpose: We sought to compare the effects of physical practice (PP) and mental practice (MP) on the immediate and long-term learning of the finger-to-thumb opposition sequence task (FOS) in children; in addition, we investigated the transfer of this learning to an untrained sequence of movements and to the contralateral untrained hand. Method:…

Strength of handedness, or the degree to which an individual prefers to use a single hand to perform various tasks, is a neurological marker for brain organization and has been shown to be linked to episodic memory, attribute framing, and anchoring, as well as other domains and tasks. The present work explores the relationship of handedness to…

This study tested the association between multiple prenatal and postnatal early life factors and adolescent sexual orientation in a longitudinal birth cohort. Factors included birth weight, gestational age, parental age at birth, number of older brothers and sisters, breastfeeding, maternal anxiety/depression, family socioeconomic position,…

Previous research on the longitudinal prediction of literacy development has focused mainly on the relationship between early cognitive/language skills and late literacy skills. The present study aimed to test the reliability of a number of measures reported by parents as compared to measuring cognitive and language skills in predicting subsequent…
