The purpose of this study was to assess the lifting performance of boys (N = 12; age 11.3 +/- 0.8 yr), teens (N = 13; age 13.6 +/- 0.6 yr), and men (N = 17; age 21.4 +/- 2.1 yr) to various rest interval (RI) lengths on the bench press exercise. Each subject performed 3 sets with a 10 repetition maximum load and a 1, 2, and 3 min RI between sets. Significant differences in lifting performance be...

Evolutionary models of cooperation require proximate mechanisms that sustain prosociality despite inherent costs to individuals. The "warm glow" that often follows prosocial acts could provide one such mechanism; if so, these emotional benefits may be observable very early in development. Consistent with this hypothesis, the present study finds that before the age of two, toddlers exhibit great...

It is by now well established that toddlers use the linguistic context in which a new word-and particularly a new verb-appears to discover aspects of its meaning. But what aspects of the linguistic context are most useful? To begin to investigate this, we ask how 2-year-olds use two sources of linguistic information that are known to be useful to older children and adults in verb guessing tasks...

Special patient populations with schizophrenia have received little attention. These populations include adolescents, the elderly, substance abusers, and patients who are considered treatment-resistant. Interest in these populations is rapidly growing, especially with regard to their treatment with second-generation antipsychotics. This article describes the treatment of special patient populat...

More US teens die from traffic crashes than from any other cause, with speed and rural roads major contributing factors. This study aimed to validate a high-fidelity simulator to explore these risks in an injury-free environment. Twenty-one newly-licensed 16-year-old males completed simulated and on-the-road drives of the same rural roads. Average free speeds on three road segments showed no sy...

T he Individuals With Disabilities Education Act (IDEA, 1990, Public Law 101-476; originally called the Education for All Handicapped Children Act of 1975 [Public Law 94-142]) provides the underpinnings for the delivery of occupational therapy to children with disabilities. Occupational therapy is included in IDEA as an educationaUy related service for children and young adults ages 3 years to ...

Some differences in behavioral characteristics have been attributed to atopic dermatitis (AD). In this study, AD patients compared with healthy toddlers had significantly higher scores in perceptual sensitivity and high pleasure in an early childhood behavior questionnaire (ECBQ). They tended to be more energetic and impulsive, and also showed more excitement when subjected to novel stimuli.

Public health guidelines for physical activity (PA) behaviors are being updated with 2018 as a proposed release date. Currently, ≥60 minutes of daily PA are recommended for youth. Thus, the purpose of this study was to investigate the association between reported days of aerobic PA and health-related fitness (HRF). Participants included 4448 students in grades 6-8. Self-reported days of ≥60 min...

The primary purpose of this paper was to provide insight into the effect of different training methods on sprinting time in male youth aged 8-18 years. Specific and nonspecific training methods were identified, the participants of the five teen studies categorized into pre, mid- and postpeak height velocity and effect sizes and percent changes calculated for each training method were appropriat...
