Psychological experiences of Korean missionary “kids” (MKs): a qualitative inquiry

The present study is a qualitative investigation of the psychological experiences of children of Korean missionaries, through the eyes of Korean missionary kids (MKs) and missionary workers. A semi-structured interview was conducted with 11 MKs and MK workers, and data were analysed using the Consensual Qualitative Research method. Several domains emerged: challenges associated with the MK experience, resiliency of MKs, intrapersonal and interpersonal coping skills, mental health concerns, religion and spirituality, a complex cultural identity, preparation for college transition, and hopes for MKs and their missionary parents. Categories corresponding to the domains are highlighted. The present study addresses a need for more attention paid to the non-American MK experience, and it presents some implications for the church and higher educational institutions.     

Mothers' Attention‐getting Utterances During Shared Book Reading: Links to Low‐income Preschoolers' Verbal Engagement,Visual Attention,and Early Literacy

This study examined associations among low‐income mothers' use of attention‐getting utterances during shared book reading, preschoolers' verbal engagement and visual attention to reading, and their early literacy skills (N = 51). Mother–child shared book reading sessions were videotaped and coded for each utterance, including attention talk, contextualized talk, de‐contextualized talk, and print talk. Preschoolers' attention during book reading was assessed using two measures: verbal engagement by using a rating scale of preschoolers' involvement in book reading discussion and visual attention by coding visual gaze. Findings indicated that mothers' attention talk was positively associated with children's verbal engagement, while maternal print talk was associated with children's visual attention. Further, low‐level maternal print talk was associated with higher early decoding scores of children when it was accompanied with high‐level maternal attention talk.

Modular Organization of Exploratory Force Development Under Isometric Conditions in the Human Arm

Muscle coordination of isometric force production can be explained by a smaller number of modules. Variability in force output, however, is higher during exploratory/transient force development phases than force maintenance phase, and it is not clear whether the same modular structure underlies both phases. In this study, eight neurologically-intact adults isometrically performed target force matches in 54 directions at hands, and electromyographic (EMG) data from eight muscles were parsed into four sequential phases. Despite the varying degree of motor complexity across phases (significant between-phase differences in EMG-force correlation, angular errors, and between-force correlations), the number/composition of motor modules were found equivalent across phases, suggesting that the CNS systematically modulated activation of the same set of motor modules throughout sequential force development.     

Does shared group identification lead to group creativity? Group regulatory focus as a moderator

Regarding the effect of identification on creativity in groups, two theoretical views compete. One view emphasizing group‐welfare motives underlying identification proposes a positive identification–creativity relationship in groups because members sharing high group identification are motivated to engage in behaviors that they believe are optimal for their group, including those that depart from the group's status quo, thus resulting in enhanced group creativity. The other view highlighting affiliative motives underlying identification, in contrast, posits a negative identification–creativity relationship in groups because highly identified members are motivated to engage in behaviors that certify their belongingness in the group, that is, behaviors that conform to the existing group norms and status quo, which constrains the group's potential for creativity. This study aims to reconcile these competing perspectives by invoking regulatory focus theory. Drawing on the notion that group identification effects rely on the content of group identity that the identification is based on, the authors suggest that group regulatory focus, as a critical group identity content, moderates the identification–creativity relationship in groups; the relationship is positive when the group's regulatory focus is highly promotion‐oriented, whereas it is negative when the group's regulatory focus is highly prevention‐oriented. Analyzing data from 65 workgroups in a cosmetics company in Korea, the authors show evidence that the identification–creativity relationship is positive in groups with a high promotion focus. The prediction regarding the prevention–focus moderation effect is not supported. The implications of the findings for both theory and practice are discussed.     

Pilot study for assessing the behaviors of patients with schizophrenia towards a virtual avatar.

This study examined whether a virtual avatar could be perceived as a real human by patients with mental disease, especially schizophrenia, as well as whether a virtual avatar could be applied to acquiring patients' behavior characteristics in a short conversation situation. The virtual avatar has been used for various applications which need to communicate with other person or to train or educate by showing humanlike behavior. Recently, many researches have shown that the virtual avatar technology has been enhanced and the avatar could be perceived like real human. A virtual avatar, standing in a virtual room, was designed for this study. Tasks to approach, initiate a talk, and answer to avatar's questions was assigned to the 11 patients with schizophrenia. As behavioral parameters in the virtual environment, the interpersonal distance and the verbal response time were acquired. In addition, the Positive and Negative Syndrome Scale (PANSS) for patients was administered in order to investigate the relationship between patients' symptomatic characteristics and behavior parameters. The interpersonal distance was negatively correlated with the negative syndrome scale, a subscale of PANSS, which is consistent with previous research reporting the relationship between interpersonal distance and a real person's image. The verbal response time, however, was not correlated with any other subscale of PANSS. After analyzing subitems of the negative syndrome of PANSS, two positive correlations were found: one was with blunted affect and the other was with poor rapport. We concluded that the virtual avatar could be perceived as a real human by schizophrenic patients and the avatar could draw the schizophrenic patients' behavior characteristics.     

VR-based conversation training program for patients with schizophrenia: a preliminary clinical trial.

Schizophrenia is a devastating mental illness and is characterized by hallucinations and delusions as well as social skills deficits. Generally, social skills training designed to help patients develop social skills includes role-playing, but this form of training has typical shortcomings, which are largely due to a trainer's difficulties to project emotion. Virtual reality (VR)-based techniques have the potential to solve these difficulties, because they provide a computer-generated but realistic three-dimensional world and humanlike avatars that can provide emotional stimuli. In this paper, we report on a method of implementing virtual environments (VEs) in order to train people with schizophrenia to develop conversational skills in specific situations, which could overcome the shortcomings of or complement conventional role-playing techniques. The paper reports the efficacy of the proposed approach in a preliminary clinical trial with 10 patients with schizophrenia.     

Characteristics of social perception assessed in schizophrenia using virtual reality.

Impairment in social skills is one of the few criteria that all individuals diagnosed with schizophrenia must meet. Successful social skills require the coordination of many abilities, including social perception, which involves the decoding and interpretation of social cues from others. In this study, we examined the potential for virtual reality (VR) in social skill training. We attempted to determine if VR can be used to measure social skills and social perception, and to determine which VR parameters are related to schizophrenic symptoms. Some of these results have clear clinical relevance, while other observations need further study. The VR system appears to be useful in assessing the social perception of schizophrenics and normal people, and could be more widely used in the future for social training and in the assessment of social problem-solving abilities, assertiveness skills, and general social skills.     

Neuroticism and psychopathy predict brain activation during moral and nonmoral emotion regulation

Functional neuroimaging has identified brain regions associated with voluntary regulation of emotion, including the prefrontal cortex and amygdala. The neural mechanisms underlying individual differences in emotion regulation have not been extensively studied. We investigated the neural correlates of neuroticism and psychopathic personality traits in the context of an emotion regulation task. Results showed that amygdala activity elicited by unpleasant pictures was positively correlated with neuroticism and negatively correlated with a specific psychopathic trait related to emotional underreactivity. During active attempts to decrease emotional responses to unpleasant pictures, superior and ventrolateral prefrontal activity was positively correlated with psychopathy, but not with neuroticism. In contrast, dorsolateral prefrontal activity was positively correlated with neuroticism, but not with psychopathy. Psychopathy was also negatively correlated with medial prefrontal activity in response to pictures depicting moral violations, suggesting reduced emotional responses to moral stimuli in individuals with high levels of psychopathic traits. These results demonstrate dissociable influences of different personality traits on neural activity associated with responses to emotional stimuli and on the recruitment of regulation-related brain activity during the active down-regulation of responses to negative emotional stimuli. These results have implications for the etiology of trait-based psychopathology involving emotional dysregulation.     

The Effects of Truth–Lie Base Rate on Interactive Deception Detection Accuracy

Consistent with the Park and Levine's (PL) probability model of deception detection accuracy, previous research has shown that as the proportion of honest messages increases, there is a corresponding linear increase in correct truth–lie discrimination. Three experiments (N = 120, 205, and 243, respectively) varied the truth–lie base rate in an interactive deception detection task. Linear base‐rate effects were observed in all 3 experiments (average effect r#x02009;= .61) regardless of whether the judges were interactive participants or passive observers, previously acquainted or strangers, or previously exposed to truths or lies. The predictive power of the PL probability model appears robust and extends to interactive deception despite PL's logical incompatibility with interpersonal deception theory.     

Impaired body but not face perception in patients with obsessive–compulsive disorder

Background. Empirical evidence involving the processing of social information by patients with obsessive–compulsive disorder (OCD) has been relatively scarce. Our study investigated the perceptual abilities of patients with OCD to recognize human faces and bodies. Method. Fifty‐four drug‐free or drug‐naïve patients with OCD and 42 healthy controls performed discrimination tasks consisting of four types of stimuli: two sets of faces that were manipulated with regard to configuration and features, human bodies, and chairs. The stimuli were presented in upright and upside‐down orientations. Results. Patients with OCD were significantly less accurate in discriminating pairs of bodily postures implying actions. However, we found no significant differences between patient and control groups in the ability to recognize faces and chairs. The inversion effects for bodies and faces were also comparable between the two groups. Conclusions. The current findings suggest that patients with OCD experience difficulty in perceiving static forms of bodily postures, but are able to adequately recognize human faces. Our data indicate a selective deficit in the perception of bodily postures in those with OCD and suggest that this deficit is probably not related to the abnormal configurational processing of social objects.
