For institutions intent on improving their research student outcomes, it is important to identify the variables most strongly associated with timely or tardy completions, which the university has the potential to influence or amend. For this to occur the analyses of doctoral completion times need to be conducted at an institution or discipline…

Objective: Bedtime procrastination is a type of unhealthy sleep behavior, but whether it affects sleep quality remains unknown. The current study aimed to examine the relationship between bedtime procrastination and poor sleep quality among Chinese college students. Participants: A total of 1550 Chinese undergraduates participated and effectively…

The incidence of consumption on Facebook around the world and its implications for university students is something that has necessarily been studied in the scientific literature (Gil-Flores, De Besa-Gutierrez & Garzón-Umerenkova, 2019). Fewer and far between are works focused on the study of social networks and academic procrastination in a…

In this study, there were 3,335 football players from four continents from around the world formed a study universe in which the causes of athlete aggression. Also, the factors affecting athlete aggression were investigated with different variables. It has been observed that the levels of aggression of footballers are different according to the…

Introduction: The readability of prescription drug labels has been found to be faster with labels attached to flat surfaces compared to round surfaces, in persons with visual impairment. This study extends this finding by examining the readability of drug labels, as measured by speed and accuracy, as they interact with factors of age and vision…

Individual differences in cognitive performance depend on age, skill, and type of task. Nonetheless, whether performance is measured with accuracy (ACC) or with the trade-off between responding speed and accuracy (SAT) could render subtle different relationships. Age and skill might associate more strongly with SAT performance in reasoning tasks,…

The increasing prevalence of digital technologies has notably expanded children's accessibility to a diverse range of digital tools day by day. Consequently, this evolution has significantly influenced the gaming landscape, propelling the surge in popularity of digital games among children. This change has also led to the need for changes in the…

Background: Recent research suggested fluent processing as an explanation on why number sense contributes to simple arithmetic tasks--'Fluency hypothesis'. Aims: The current study investigates whether number sense contributes to such arithmetic tasks when other cognitive factors are controlled for (including those that mediate the link); and…

Cyberbullying is by an individual or a group by using resources such as e-mail, smart phone, pagers, short message services (SMS) and websites, Information and Communication technologies in order to harm a person; intentional, repetitive hostile behavior.

The present study considered multiple aspects of sleep in a community sample of young children (at ages 30, 36, and 42 months) and their mothers, using both diaries and actigraphy. Through principal components analysis, 17 of 20 commonly used actigraphy variables were reduced to four main components whose variables formed composites of: Activity,…

Leisure reading is a main contributor to print exposure, which is in turn related to individual differences in reading and language skills. The Author Recognition Test (ART) is a brief and objective measure of print exposure that has been used in reading research since the 1990s. Life span studies have reported contradicting results concerning age…

By approximately 6 years of age, children can use time-based visual selection to ignore stationary stimuli, already in the visual field and prioritize the selection of newly arriving stimuli. This ability can be studied using preview search, a version of the visual search paradigm with an added temporal component, in which one set of distractors…

Goals: This study examined: (a) crystallized/fluid intelligence trajectories of adolescents and adults with Down syndrome; and (b) the contribution of endogenous (health, activities of daily living--ADL) and exogenous (cognitively stimulating leisure activities) factors on adults' intelligence with age. Method: Four cohorts (N = 80) with Down…

The present study examined individual differences in the development of sustained attention across toddlerhood, as well as how these individual differences related to the development of language and sleep. Toddlers (N = 314; 54% male) were assessed at 30, 36, and 42 months using multiple measures of attention, a standardized language assessment,…

Inhibitory control is a core executive function that develops during childhood and is measured with tasks that require the inhibition of a dominant response. The current study examined the diagnostic value of using response accuracy and latency in a simple inhibitory control test, the computerized Pointing-Stroop Task (cPST), for kindergarten…
