  • Stimulants, such as amphetamine and methylphenidate, are one of the most effective treatment modalities for attention deficit hyperactivity disorder (ADHD) and may cause various movement disorders. This review discusses various movement disorders related to stimulant use in the treatment of ADHD. We reviewed the current knowledge on various movement disorders that may be related to the therapeutic use of stimulants in patients with ADHD. Recent findings suggest that the use of stimulants and the onset/aggravation of tics are more likely to be coincidental. In rare cases, stimulants may cause stereotypies, chorea, and dyskinesia, in addition to tics. Some epidemiological studies have suggested that stimulants used for the treatment of ADHD may cause Parkinson's disease (PD) after adulthood. However, there is still a lack of evidence that the use of stimulants in patients with ADHD may cause PD, and related studies are only in the early stages. As stimulants are one of the most commonly used medications in children and adolescents, close observations and studies are necessary to assess the effects of stimulants on various movement disorders, including tic disorders and Parkinson's disease.

  • Travel distance is a parameter mainly used in the objective function of Construction Site Layout Planning (CSLP) automation models. To obtain travel distance, common approaches, such as linear distance, shortest-distance algorithm, visibility graph, and access road path, concentrate only on identifying the shortest path. However, humans do not necessarily follow one shortest path but can choose a safer and more comfortable path according to their situation within a reasonable range. Thus, paths generated by these approaches may be different from the actual paths of the workers, which may cause a decrease in the reliability of the optimized construction site layout. To solve this problem, this paper adopts reinforcement learning (RL) inspired by various concepts of cognitive science and behavioral psychology to generate a realistic path that mimics the decision-making and behavioral processes of wayfinding of workers on the construction site. To do so, in this paper, the collection of human wayfinding tendencies and the characteristics of the walking environment of construction sites are investigated and the importance of taking these into account in simulating the actual path of workers is emphasized. Furthermore, a simulation developed by mapping the identified tendencies to the reward design shows that the RL agent behaves like a real construction worker. Based on the research findings, some opportunities and challenges were proposed. This study contributes to simulating the potential path of workers based on deep RL, which can be utilized to calculate the travel distance of CSLP automation models, contributing to providing more reliable solutions.

  • The goal of the research is to identify the relationship between organizational justice, job satisfaction, and work attitudes in the context of job rotation. The competence and loyalty of the employees of an organization are critical to the organization's success. Therefore, organization should invest in developing their employees, including creating effective procedures and human resource management policies. A job rotation program is one of the critical policies in developing employees, as through this program employees can develop and actualize their abilities. However, there are some challenges in practice regarding implementing the procedures of job rotation. One of the challenges is related to the concept of organizational justice, which then impacts on employees' job satisfaction and work attitudes. This study was conducted in focused group discussions. The sample is 272 of a state-owned organization. In this study, the concept of organizational justice, with the dimensions of distributive justice, procedural justice, and interactional justice, were used along with the discussion of job satisfaction and other work attitudes. The results were issues of fairness in perceiving organizational justice in the job rotation context, and the most significant response lies in procedural justice.

  • Previous research has shown that employees tend to react more positively to corrective feedback from supervisors to the extent they perceive that they were treated with empathy, respect, and concern towards fair interpersonal treatment in receiving the feedback information. Then, to facilitate effective supervisory feedback and coaching, it would be useful for organizations to monitor the contents of feedback exchanges between supervisors and employees to make sure that supervisors are providing performance feedback using languages that are more likely to be perceived as interpersonally fair. Computer-aided text analysis holds potential as a useful tool that organizations can use to efficiently monitor the quality of the feedback messages that supervisors provide to their employees. In the current study, we applied computer-aided text analysis (using closed-vocabulary text analysis) and machine learning to examine the validity of language-based algorithms trained on supervisor language in performance feedback situations for predicting human ratings of feedback interpersonal fairness. Results showed that language-based algorithms predicted feedback interpersonal fairness with reasonable level of accuracy. Our findings provide supportive evidence for the promise of using employee language data for managing (and improving) performance management in organizations.

  • This study is to apply behavioral economics-an economics that studies actual human behavior based on cognitive psychology-to the farming decision-making process of onion and garlic farmers. Of behavioral economic theories, dual system theory and prospect theory (value function), heuristic and bias were surveyed and examined in the field. The reference point of farmers was farming experience of the previous year, and so they showed reference dependence and anchoring heuristic, not rational thinking on production cost plan. And they showed status quo bias that cultivated continuously the previous year or the present crop. This status quo bias is related to loss aversion propensity. Farmers did not usually change cultivating crops, in other words, they showed diminishing sensitivity-insensitive to those that the more revenue or loss was increased. This diminishing sensitivity is related to loss aversion propensity and status quo bias. Also, farmers had representativeness heuristic because they regarded auction price of Garakdong wholesale market as the standard price level despite various prices by production region. And farmers had the affect heuristic that they depended on producers' organization data more than the state-run research institute ones about cultivation intentions and actual situations.

  • This study was carried out to examine whether children had the naive psychological knowledge that the mental states ate requited to understand the intentional actions, whether their psychological knowledge was organized as a theory, and in what aspects the knowledge changed as children get older. Three- to 11-year-olds were presented with two types of tasks. In action explanation tasks, children were presented with simple descriptions of two characters engaging in specific actions and then asked to explain the characters' action. In action prediction tasks, they were told stories depicting a character's desire and belief and then asked to predict the action of the character. Three-year-olds explained the action in terms of abstract construct such as emotion, intention, and desire, and they predicted the character's action on the basis of her/his desire and explicit belief but not on the basis of inferred false belief and traits. In addition when they were asked to explain one mental state, they explained in terms of other mental states, suggesting the coherence of their knowledge. The present results suggested that even 3-year-olds' psychological knowledge was organized as a theory, in that it was used as a causal device in explaining and predicting human actions, and it had abstractness and coherence. Older children's knowledge was different from 3-year-olds' in that older children explained the action in terms of more complicated mental states such as beliefs and traits. The nature of the developmental change in psychological knowledge was discussed.

  • Current neuroscience views the mind-body problem from the monistic perspective which claims that the human mind is the result of brain activity and that the mind shuts down when the brain does. However, a considerable number of lay people still believe in the existence of the soul and the afterlife, concepts that are hard to explain from the monistic perspective. This study examines whether lay people think that the mind of the dead is capable of exceeding the physical constraints if they believe that such mind exists. After reading one of three vignettes which describes the state of the protagonist as alive, dead, or brain dead, the participants evaluated the protagonist's general mental capacity and transcendental ability to obtain new information. The participants rated that the dead protagonist had more 'transcendental ability to obtain new information' than the alive one if they evaluated high general mental capacity to the protagonist. In addition, unlike the alive condition, in the dead and the brain dead condition, there was a correlation between the general mind capacity rating and the transcendental ability rating. The results suggest that lay people expect the mind of the alive and the dead to be different, as they believe the latter's general mind capacity connotes transcendental ability. We also found that the participants' religiosity affected their beliefs about the transcendental ability of dead person.

  • It is known that Psychopathy is excessively selfish, using as a tool to achieve the purpose to others, irresponsible, easy liars in common. They were recognized that it is people of harmful to society, impulsive, attacking others body, ignorant others safety, enjoying or callousing others suffers. But, another aggressive behaviors are described as pro-social aggressive acts as the cops bring under control by firearms to hostage committing a crime in social norms. The proper aggression is related with national security and safety of the people that is pro-social aggression for nation and human society. Security service with the legal grounds and the convinced commitment needs self-giving works, self-sacrificial security-activity is in the center of security service. These days, psychologists reveal the people of psychopathy are CEO, politician, broadcaster, surgeon, special forces, police officer. And they distinguish themselves and contribute to a community in various fields. Therefor, this research wanted to find out the relationship between fearlessness, coldheartedness in the PPI-R(applying to the university student for checking psychopathy, except anti-social traits) and pro-social aggression, self-sacrificial security-activity.

  • Kon Satoshi is a representative animation film director who explores human's intrinsic self-identity based on ambivalence and delivers a message for self-reflection of entity. The aim of this study is to analyze the persona of character according to the way how a self incorporates with another self in his film; that is to say, how a mask of the personality expresses and realizes itself from the perspectives of the Jung's analytical psychology. The persona, defined as the upmost external personality, involves social behavior playing a specific role to establish constant relationship with others in a society. With increasing demand in a society, individuals get to adapt to outer environment by playing his/her given role in various masks of personality. In this way, although persona acts as a major function in relationship with outer world, it would exert a negative influence on formation of self-identity because of the inconsistency between consciousness and unconsciousness when immersed only in mask of personality, complying excessively with the demand of group. However, persona does not always have a negative effect on relationships. Developed adequately to fulfill its social function, persona is helpful to establish a healthy self-identity with balanced control between inner world of unconsciousness and outer world of consciousness. From these perspectives, this study can identify how the desire of mask hidden inside of each character expresses to function in a positive or negative way by analyzing characters in the film according to integrated pattern and correlation between consciousness and unconsciousness. Additionally, I hope that the psychological research methods in this study will be full of help for interpreting on a character analysis as a theoretical approach.

  • This study examined effects of gender and empathic emotional expression of an anthropomorphic interface agent on users. assessment of the agent. In addition, it examined effects of gender and emotional expression regardless of whether visual fidelity of the agent. In Study 1, The agents were manipulated by photographs of human face. The agent expressed empathic emotion by making an other-oriented emotional response congruent with another's perceived welfare. Subjects participated in a task with the agent and then they assessed the agent by rating interpersonal assessment scale. The result reported their preference to the female agent. In addition, they tended to make positive assessment to the agent of opposite gender. In the study 2, gender and expressed emotion of the agent with low fidelity was manipulated. Subjects participated in a task with the agent and then they assessed the agent by rating the same interpersonal assessment scale as study 1. The result reported their preference to the female agent. In addition, they preferred the agent expressing empathic emotion to the agent expressing self-oriented emotion or no emotion. Though the agent had low visual fidelity, its gender and expressed empathic emotion could make a significant effect on users' assessment.
