Arts and Cultural Activities and Happiness: Evidence from Korea

The purpose of this paper is to examine the relationship between attending arts and cultural activities and individual happiness. We classify arts and cultural activities into four categories according to their characteristics: visual arts, performing arts, movies, and sporting events. Our results show that arts and cultural activities have a positive relationship with individual happiness. More specifically, the coefficient for attending performing arts is the highest, and the fall in marginal utility of participation is the lowest for movies. In addition, the benefit from arts and cultural activities is greater in the low-income group than in the high-income group; however, visual arts activities are statistically significant in the high-income group. Through the interaction between household types and cultural activities, we find that the utility increments for performing arts and movies occur in the high-income group. Our results can provide insight for government organizations involved in the promotion of the arts and cultural activities.

     

Evolution and the nonlegal equivalent of aggressive criminal behavior

Within the framework of modern evolutionary theory, arguments are reviewed that the nonlegal equivalent of aggressive criminal behavior may have evolved by natural selection among mammals, particularly primates, as part of their overall approach to reproduction. If so, the commission of aggressive crimes (or their nonlegal equivalent) by humans, and even efforts to prevent fellow social group members from being victimized by aggressive crimes, may also be partially explainable in natural selection terms. The plausibility of this deduction was explored, first, by specifying the three elements that a human act must have to be regarded as an aggressive crime. Summarily, these were that (1) injury to a victim must be a likely result of the act, (2) the act must be intended, and (3) the act must elicit negative responses from those witnessing it. The primate behavior literature was examined for evidence that some behavior of nonhumans met all three conditions. Affirmative results were obtained. Therefore, while further research is in order, human aggressive criminal behavior, as well as human efforts to control it, seem to have close parallels in other primates. This would be consistent with the notion that aggressive criminal behavior (along with its condemnation by fellow group members) is part of a social system produced and sustained by natural selection.     

Defensive reactions of “wild-type” and “Domesticated” wild rats to approach and contact by a threat stimulus

Selective breeding of wild rats over many generations on the basis of low or high defensive threat and attack to human approach and contact has produced highly polarized “domesticated” and “wild-type” animals. Because the selection procedure selectively involves these two defense patterns, and these clearly differ in the two groups, it is of interest to determine if other, nonselected, defensive behaviors to threat stimuli also change. “Domesticated” and “wild-type” rats of the thirty-fifth generation were run in a fear defense test battery (F/DTB) to systematically evaluate defensive behaviors to a variety of present threat stimuli. “Domesticated” rats showed reduced avoidance and slower flight speed to an approaching experimenter, reduced jump/startle response to handelap and dorsal contact, less vocalization and boxing to vibrissae stimulation or to an anesthetized conspecific, and reduced defensiveness to an attempted pickup by the experimenter. These results indicate that selective bi-directional breeding for defensive threat and attack to human approach and contact produces group differences in a variety of defensive behaviors, and in defensiveness to stimuli other than those on which the selection was based. © 1994 Wiley-Liss, Inc.     

A review of attachment-based parenting interventions: Recent advances and future considerations

Research evidence has shown that in childhood, a secure attachment to a reliable caregiver is important for future mental health and well-being. The theoretical and research basis for attachment theory continues to grow. As attachment theory has become more widely adopted there are challenges and opportunities both theoretically and in terms of its clinical use. Disordered attachment has been linked to psychopathology including internalising and externalising disorders. However, there are ongoing implications for researchers and clinicians as only the most extreme forms of attachment disorders are included in the current diagnostic systems. A wide range of reliable and validated observational assessments to classify attachment are available. Owing to the growing popularity of attachment-based interventions there is a need to develop assessments which are practical for use in clinical settings. The use of attachment-based parenting interventions in clinical settings is increasing as they have been found to be effective and relevant. This growth presents opportunities to further refine these interventions, so they are easy to deliver in clinical practice and tailored to different populations. Attachment-based interventions are being widely used in Australia, and this has led to a need to understand and adapt the theory, assessments, and interventions to this context. Attachment-based interventions demonstrate the importance of relationships and provide an important tool to support children and families. For psychologists here in Australia there are many opportunities to develop measures and interventions based on attachment theory that fit into the Australia context.     

Explaining the Asian American Youth Paradox: Universal Factors versus Asian American Family Process Among Filipino and Korean American Youth

This study used longitudinal survey data of Filipino American and Korean American youth to examine ways in which universal factors (e.g., peer antisocial behaviors and parent–child conflict) and Asian American (AA) family process variables (e.g., gendered norms) independently and collectively predict grade point average (GPA), externalizing, and internalizing problems. We aimed to explain the “Asian American youth paradox” in which low externalizing problems and high GPA coexist with high internalizing problems. We found that universal factors were extensively predictive of youth problems and remained robust when AA family process was accounted for. AA family process also independently explained youth development and, in part, the AA youth paradox. For example, gendered norms increased mental distress. Academic controls did the opposite of what it is intended, that is, had a negative impact on GPA as well as other developmental domains. Family obligation, assessed by family-centered activities and helping out, was beneficial to both externalizing and internalizing youth outcomes. Parental implicit affection, one of the distinct traits of AA parenting, was beneficial, particularly for GPA. This study provided important empirical evidence that can guide cross-cultural parenting and meaningfully inform intervention programs for AA youth.     

Getting older and living up to implicit followership theories: Implications for employee psychological health and job attitudes

Age discrimination at work is a widespread destructive phenomenon that often takes subtle forms. Based on negative stereotypes about older employees, we argue that older employees often experience that they are perceived as less ideal followers than younger employees. We propose that older and younger employees do not differ in what they assume their supervisors expect of an ideal follower (implicit followership theories, IFTs). Thus, we hypothesize that older employees perceive that they compare less favorably to their supervisors' IFTs than younger employees (i.e., worse IFT-fit). This should entail lower quality of the relationship between leader and follower (leader-member-exchange, LMX), which, in turn, should have detrimental effects on employees' health (i.e., burnout) and job attitudes (i.e., job satisfaction, turnover intentions, and identification). We tested our model in a field study with 379 employees. Results differed for ideal and counter-ideal follower attributes. Concerning counter-ideal follower attributes (e.g., being incompetent), age had the proposed negative effect on psychological health and job attitudes that mediated through IFT-fit and LMX. Concerning ideal follower attributes (e.g., thinking ahead), older employees expected their supervisors not only to think less of them than of their younger colleagues, but also expected them to have less demanding IFTs—contrary to our expectations. Employee age was negatively related to psychological health and job attitudes, mediated through lower perceived IFTs, worse perceived appraisal of the actual employee and their joint effects on LMX.     

Bilateral Transcranial Direct Stimulation Over the Primary Motor Cortex Alters Motor Modularity of Multiple Muscles

Abstract

Transcranial direct current stimulation (tDCS) over the primary motor cortex (M1) has been demonstrated to modulate the motor performance of both healthy individuals and patients with neuromuscular disorders. However, the effect of tDCS on motor control of multiple muscles, which is a prerequisite to change in motor performance, is currently unknown. Using dimensionality reduction analysis, we investigated whether bilateral tDCS over M1 modulates the coordinated activity of 12 muscles. Fifteen healthy men participated in this randomized, double-blind crossover study. Each participant received a 20-min sham and 2-mA stimulation bilaterally over M1 (anode on the right M1 and cathode on the left M1), with a minimum washout period of 4?days. Muscle activation and end-point kinematics were evaluated during a task where participants reached out to a marked target with non-dominant hand as fast as possible, before and immediately after tDCS application. We found decreased similarity in motor modularity and significant changes in muscle activation in a specific motor module, particularly when reaching out to a target placed within arm’s length and improved smoothness index of movement only following 2-mA stimulation. These findings indicate that clinicians and researchers need to consider the simultaneous effect of bilateral tDCS over M1 on multiple muscles when they establish tDCS protocol to change in motor performance of patients with neuromuscular deficits.
