Opposite reactions to loss incentive by young and older adults: Insights from diffusion modeling.

The prospect of loss becomes more salient in later life, and the opportunity to avoid loss is often used to motivate older adults. We examined the effect of loss incentive on working memory in young and older adults. Diffusion-modeling analyses, manipulation of task parameters, and self-report measures identified which aspects of cognitive-motivational processing were most affected within each group.

Interactions between methodological and interindividual variability: How Monetary Incentive Delay (MID) task contrast maps vary and impact associations with behavior.

Introduction: Phenomena related to reward responsiveness have been extensively studied in their associations with substance use and socioemotional functioning. One important task in this literature is the Monetary Incentive Delay (MID) task. By cueing and delivering performance-contingent reward, the MID task has been demonstrated to elicit robust activation of neural circuits involved in different phases of reward responsiveness.

Losing Money and Motivation: Effects of Loss Incentives on Motivation and Metacognition in Younger and Older Adults.

Major Stressors among Korean Adolescents According to Gender, Educational Level, Residential Area, and Socioeconomic Status.

Adolescents are exposed to many stressors which have been associated with poor mental health. Using data from the 2015 Korea Youth Risk Behavior Web-based Survey, we identified the major stressors among Korean adolescents based on gender, current educational level, residential area, and socioeconomic status (SES). The major stressors among girls were relationship- and appraisal-related factors, whereas boys more often reported health- and conflict-related factors.

Differential effects of completed and incomplete pregnancies on the risk of Alzheimer disease.

Objective: To investigate the effects of completed pregnancy with childbirth and incomplete pregnancy without childbirth on the late-life cognition and the risk of Alzheimer disease (AD) in women.

Methods: Using the pooled data of 3,549 women provided by 2 population-based cohort studies, we conducted logistic regression analyses to examine retrospectively the associations of completed and incomplete pregnancy with the risks of mild cognitive impairment and AD. For women without dementia, we also conducted analyses of covariance to examine the associations of completed and incomplete pregnancy with Mini-Mental State Examination (MMSE) score.

Psychometric Properties of the Korean Translation of the Attention-Deficit/Hyperactivity Disorder Stigma Questionnaire.

Objectives: This study evaluated the psychometric properties of the Korean version of the attention-deficit/hyperactivity disorder (ADHD) Stigma Questionnaire (ASQ) and the effect of the source of information about mental health on ADHD stigma.

Methods: The Korean translation of the ASQ was prepared, and 673 participants, 20-64 years of age, completed the questionnaire using an online panel survey in South Korea. The participants also completed questionnaires detailing sociodemographic variables and the source of their mental health knowledge.

Health Behaviors, Physical Health, and Health Care Utilization in Children With ADHD.

To compare health behaviors, physical health outcomes, and health care utilization between children with and without ADHD. : In this cross-sectional study, we obtained data for children with and without ADHD from the Korean National Health and Nutrition Examination Survey. To investigate the association between ADHD and health outcomes, we estimated the adjusted prevalence ratios (APRs) in these groups.

The Prevalence of Chronic Physical Diseases Comorbid with Depression among Different Sex and Age Groups in South Korea: A Population-Based Study, 2007-2014.
