Changes in childhood caregiving impressions among middle-aged and older adults

Childhood experiences and impressions are important for individuals' health and well-being—they often set the stage for how people approach relationships across the lifespan and how they make sense of their relational worlds. However, impressions of these experiences are likely not static and can change over time, even years after these experiences happened. The current study examined how impressions of parental relationships in childhood changed over time, and predictors of these changes, among middle-aged and older adults followed over a 4-year period (N = 2692; M_age = 66.67, SD = 9.15; 64.1% women). Childhood impressions of parental care were mostly stable over time, with 53.5%–65.0% of participants reporting consistent impressions. Becoming divorced/separated as an adult was associated with more negative impressions about relationships with fathers in the past. Having a mother pass away was associated with more positive impressions of mothers' caregiving when participants were children. Higher depressive symptoms at follow-up were associated with darker perceptions of the past—more negative impressions of mothers and fathers as caregivers. The current study is one of the most comprehensive studies of late-life changes in childhood impressions to date, suggesting future directions for studying the organization of relational experiences and recollection over time.     

A computer art assessment system for the evaluation of space usage in drawings with application to the analysis of its relationship to level of dementia

Space usage in drawings is an important element that provides useful information about the drawer’s level of energy and psychological status. In this paper, we delineate the development of a computer system to objectively and quantitatively evaluate the space usage using regression models and computer analysis. We formulate regression models whose dependent variables are the grades and the ranks of space usages. We emphasize the contribution of the area of the painted convex hull in explaining the grades and ranks, which we propose as an independent variable. All possible independent variables including the area of painted regions and the number of colors used are evaluated by the computer algorithms developed in this study. We measure the validity of the system for evaluating grades and ranks. As an application to a real case, the system has been used to investigate the relationship between the space usage and the level of dementia.     

Asian Values,Ethnic Identity,and Acculturation Among Ethnic Asian Wives in South Korea

In Korea as of 2009, the immigrant population comprised less than 2.5 % of the total population, whereas almost one in ten marriages taking place during the same year was international, of which more than 75 % were ethnic Asian women married to Korean men. On that ground, this study addresses the importance of Asian values and ethnic identity in ethnic Asian wives’ acculturation to Korean society. The subjects of this study have been selected from three ethnic Asian groups—Japanese, Chinese, and Vietnamese women. Acculturation in this study has been measured in three aspects: Korean cultural attitudes and identity, linguistic assimilation, and the level of satisfaction with Korean culture. First, our findings have revealed that their recognition of Asian values plays an important role in improving their acculturation to Korean society, especially in the realms of cultural attitudes and identity, and satisfaction with Korean culture. Then, there has been no evidence that their sense of ethnic identity is a critical factor of their acculturation to Korean society.     

The Interactive Effect of Conscientiousness and Agreeableness on Job Performance Dimensions in South Korea

While much is known about the effects of personality traits on performance, there is still limited empirical evidence that examines how personality traits may interact with each other to impact dimensions of performance. This study examined how conscientiousness and agreeableness interact to predict both task performance and organizational citizenship behavior using a sample of 113 bank employees in South Korea. The interaction between the two personality traits was significantly related to both dimensions of performance.     

Comparative analyses of rider position according to skill levels during walk and trot in Jeju horse

The purpose of this study was to evaluate the rider position at walk and trot as a function of rider skill level by analyzing joint angles. Participants included three advanced riders and six beginners, and training was conducted for one hour, twice a week for 24 weeks. In the walk stage of the beginners’ group, the elbows and shoulders sustained postures comparable to those of the advanced riders group; the trunk tilted forwards at first, but later it tilted slightly behind the vertical. The knee, ankle, and left–right angle kept stable postures after 12 weeks of training (p < .05). The front-rear (FR) angle of the beginners group improved during training, but it was still lower than the advanced riders group after 24 weeks of training (p < .05). At trot, while the knee angle measurement of the beginners’ group was similar to the advanced riders, the ankle joint sustained a forward point posture. The ankle joint maintained dorsiflexion posture with 83.9° ± 5.3 in the advanced riders group, while the beginners group had plantar flexion posture with 98.7° ± 6.0. This study suggested that the correlation between the joint and body segment angles could be an important indicator in the evaluation of rider proficiency.     

Trajectories of Social Withdrawal from Middle Childhood to Early Adolescence

Heterogeneity and individual differences in the developmental course of social withdrawal were examined longitudinally in a community sample (N = 392). General Growth Mixture Modeling (GGMM) was used to identify distinct pathways of social withdrawal, differentiate valid subgroup trajectories, and examine factors that predicted change in trajectories within subgroups. Assessments of individual (social withdrawal), interactive (prosocial behavior), relationship (friendship involvement, stability and quality, best friend’s withdrawal and exclusion/victimization) and group- (exclusion/victimization) level characteristics were used to define growth trajectories from the final year of elementary school, across the transition to middle school, and then to the final year of middle school (fifth-to-eighth grades). Three distinct trajectory classes were identified: low stable, increasing, and decreasing. Peer exclusion, prosocial behavior, and mutual friendship involvement differentiated class membership. Friendlessness, friendship instability, and exclusion were significant predictors of social withdrawal for the increasing class, whereas lower levels of peer exclusion predicted a decrease in social withdrawal for the decreasing class.     

CATOS (Computer Aided Training/Observing System): Automating animal observation and training

In animal behavioral biology, an automated observing/training system may be useful for several reasons: (a) continuous observation of animals for documentation of specific, irregular events, (b) long-term intensive training of animals in preparation for behavioral experiments, (c) elimination of potential cues and biases induced by humans during training and testing. Here, we describe an open-source-based system named CATOS (Computer Aided Training/Observing System) developed for such situations. There are several notable features in this system. CATOS is flexible and low cost because it is based on free open-source software libraries, common hardware parts, and open-system electronics based on Arduino. Automated video condensation is applied, leading to significantly reduced video data storage compared to the total active hours of the system. A data-viewing utility program helps a user browse recorded data quickly and more efficiently. With these features, CATOS has the potential to be applied to many different animal species in various environments such as laboratories, zoos, or even private homes. Also, an animal’s free access to the device without constraint, and a gamified learning process, enhance the animal’s welfare and enriches their environment. As a proof of concept, the system was built and tested with two different species. Initially, the system was tested for approximately 10 months with a domesticated cat. The cat was successfully and fully automatically trained to discriminate three different spoken words. Then, in order to test the system’s adaptability to other species and hardware components, we used it to train a laboratory rat for 3 weeks.     

The Effects of Marital Conflict on Korean Children’s Appraisal of Conflict and Psychological Adjustment

This study examined the effects of marital conflict on Korean children’s psychological adjustment and appraisal of hypothetical marital conflict situations. Children between the ages of 10 and 12 were divided into “high-conflict” (n = 58) and “low-conflict” (n = 58) groups based on their self-reported degree of perceived interparental conflict in the home environment. Hypothetical marital conflict situations were provided in cartoon format, and were differentiated based conflict intensity (verbal versus physical aggression) and content (child-related conflict versus non-child-related conflict). In general, children reported greater negative affect and perceived threat to hypothetical conflict situations involving physical aggression compared to situations involving verbal conflict. In child-related conflict situations, children reported more fear of being drawn in and endorsed coping strategies that involved direct intervention. “High-conflict group” children evidenced stronger reactivity in responding to marital conflict situations in general and endorsed indirect intervention strategies—a finding previously not found in similar studies conducted with European-American children—indicating the possibility of cross-cultural difference in coping preferences in interparental conflict situations. Furthermore, “high-conflict group” children manifested more indices of maladjustment as indicated by externalizing and internalizing behavior problems, in addition to more self-reported depressive symptoms. Results highlight the effects of marital conflict on children’s psychological adjustment and indicate the possibility of cross-cultural differences in preferred coping mechanism in interparental conflict situations for Korean children.     

Too much of a good thing: curvilinear relationships between personality traits and job performance

The relationships between personality traits and performance are often assumed to be linear. This assumption has been challenged conceptually and empirically, but results to date have been inconclusive. In the current study, we took a theory-driven approach in systematically addressing this issue. Results based on two different samples generally supported our expectations of the curvilinear relationships between personality traits, including Conscientiousness and Emotional Stability, and job performance dimensions, including task performance, organizational citizenship behavior, and counterproductive work behaviors. We also hypothesized and found that job complexity moderated the curvilinear personality–performance relationships such that the inflection points after which the relationships disappear were lower for low-complexity jobs than they were for high-complexity jobs. This finding suggests that high levels of the two personality traits examined are more beneficial for performance in high- than low-complexity jobs. We conclude by discussing the implications of these findings for the use of personality in personnel selection.
