Disaggregating the effects of acculturation and acculturative stress on the mental health of Asian Americans

This study examines the impact of level of acculturation and acculturative stress on the mental health of Asian American college students. Hierarchical regression analyses were used to clarify the relation between level of acculturation, acculturative stress, and mental health outcomes (psychological distress and clinical depression). Being less identified with mainstream United States culture was associated with higher psychological distress and clinical depression, but lost significance when acculturative stress was introduced into the model. Retention or relinquishing of identification with one's heritage culture was not associated with mental health outcomes. Although understanding level of acculturation can help us identify those at risk, findings suggest that acculturative stress is a more proximal risk factor and increases risk for mental health problems independently of global perceptions of stress.     

Statistical processing: not so implausible after all

Myczek and Simons (2008) have shown that findings attributed to a statistical mode of perceptual processing can, instead, be explained by focused attention to samples of just a few items. Some new findings raise questions about this claim. (1) Participants, given conditions that would require different focused attention strategies, did no worse when the conditions were randomly mixed than when they were blocked. (2) Participants were significantly worse at estimating the mean size when given small samples than when given the whole display. (3) One plausible suggested strategy--comparing the largest item in each display, rather than the mean size--was not, in fact, used. Distributed attention to sets of similar stimuli, enabling a statistical-processing mode, provides a coherent account of these and other phenomena.     

Applying the Lifestyle Routine Activities Theory to Understand Physical and Nonphysical Peer Victimization

Peer victimization is a serious problem, and understanding where, with whom, and how long victims spend their time is important. Applying the lifestyle routine activities theory (LRAT), this study examines the association between 4 components of LRAT and physical and nonphysical peer victimization. Using the 2007 National Crime Victimization Survey, we examined Poisson and negative binomial regression models to explain whether physical and nonphysical peer victimization was affected by measures of routine activities. Our findings indicate that students’ exposure and proximity to motivated offenders, school environment, capable guardianship, and target attractiveness were associated with risk of peer victimization. Findings also reveal that risk factors varied depending on the type of victimization.     

The role of negative publicity in consumer evaluations of sports stars and their sponsors

This paper aims to specify and test empirically the impact that two types of negative information (immorality and incompetence) about a sports star have on consumers' perceptions of the sports star and the sponsor. The moderating role of game relevance (game‐related and non‐game‐related) and fan identification with a sports star (high identification and low identification) are also investigated. Using a sample of South Korean consumers (n = 249), we found in the experiment that the type of negative information affects participants' attitudes toward the sports star and the sponsor. This result implies that a sports star's involvement in negative events not only damages the star's reputation but also detracts from the value of the sponsor company. The results also show that the two factors moderate the main effects of negative publicity on consumers' perception of the sports star and his or her sponsor. First, the negative publicity about the sports star's functional issues (e.g., a career‐threatening injury) negatively affects consumer attitude toward the sports star and the sponsor more in the out‐of‐game context than in the in‐game situation. Second, bad sports star publicity has a greater negative effect on consumer perception of sponsors for lowly identified than highly identified sports stars, while the moderating effect on consumer perception of the sports star is not significant. Detailed practical implications and academic contributions are discussed. Copyright © 2017 John Wiley & Sons, Ltd.     

A comparative study on the flow experience in web-based and text-based interaction environments

The purpose of this study was to explore a substantial phenomenon related to flow experiences (immersion) in text-based interaction systems. Most previous research emphasizes the effects of challenge/skill, focused attention, telepresence, web characteristics, and systems' interface design on users' flow experiences in online environments. However, text-based interaction systems without telepresence features and web characteristics still seem to create opportunities for flow experience. To explore this phenomenon, this study incorporates subject involvement and interpersonal interaction as critical antecedents into the model of flow experience, as well as considers the existence of telepresence. Results reveal that subject involvement, interpersonal interaction, and interactivity speed are critical to focused attention, which enhances users' immersion. With regard to the effect of telepresence, the perceived attractiveness of the interface is a significant facilitator determining users' immersion in web-based, rather than in text-based, interaction environments. Interactivity speed is unrelated to immersion in both web-based and text-based interaction environments. The influence of interpersonal involvement is diminished in web-based interaction environments. The implications and limitations of this study are discussed.     

Cathodal transcranial direct current stimulation of the right Wernicke's area improves comprehension in subacute stroke patients

Previous studies have shown the appearance of right-sided language-related brain activity in right-handed patients after a stroke. Non-invasive brain stimulation such as transcranial direct current stimulation (tDCS) and repetitive transcranial magnetic stimulation (rTMS) have been shown to modulate excitability in the brain. Moreover, rTMS and tDCS have been found to improve naming in non-fluent post-stroke aphasic patients. Here, we investigated the effect of tDCS on the comprehension of aphasic patients with subacute stroke. We hypothesized that tDCS applied to the left superior temporal gyrus (Wernicke’s area) or the right Wernicke’s area might be associated with recovery of comprehension ability in aphasic patients with subacute stroke. Participants included right-handed subacute stroke patients with global aphasia due to ischemic infarct of the left M1 or M2 middle cerebral artery. Patients were randomly divided into three groups: patients who received anodal tDCS applied to the left superior temporal gyrus, patients who received cathodal tDCS applied to the right superior temporal gyrus, and patients who received sham tDCS. All patients received conventional speech and language therapy during each period of tDCS application. The Korean-Western Aphasia Battery (K-WAB) was used to assess all patients before and after tDCS sessions. After intervention, all patients had significant improvements in aphasia quotients, spontaneous speech, and auditory verbal comprehension. However, auditory verbal comprehension improved significantly more in patients treated with a cathode, as compared to patients in the other groups. These results are consistent with the role of Wernicke’s area in language comprehension and the therapeutic effect that cathodal tDCS has on aphasia patients with subacute stroke, suggesting that tDCS may be an adjuvant treatment approach for aphasia rehabilitation therapy in patients in an early stage of stroke.     

The stability of mastery motivation and its relationship with home environment in infants and toddlers

Mastery motivation (intrinsic drives to explore and master one's environment) is a key developmental element. The aims of this study were to investigate (1) the stability of mastery motivation between 2 and 3 years of age for two genders; and (2) the associations between early home environment and toddlers’ mastery motivation in children with typical development.

Methods

Data of 102 children developing typically from a birth cohort study at Northern Taiwan were analyzed in two parts: (1) stability part: mastery motivation of children were measured at 2 and 3 years of age; (2) environment part: child-parent dyads were assessed from birth, 4 months, 6 months, and 2-3 years of age. Outcomes variables were measured at ages 2 and 3 years by the Dimension of Mastery Questionnaire-17th version. Main predictive variables were measured by Home Observation for Measuring Environment Inventory (HOME) to collect data of the qualities of home environment at 6 months and 2 years; by the Revised Infant Temperament Questionnaire to obtain 4-month activity levels; and by the Comprehensive Developmental Inventory for Infants and Toddlers to obtain 2-year developmental quotient (DQ).

Results

There was moderate stability of mastery motivation from 2 to 3 years, and girls’ stability was higher than boys’. 6-Month HOME rather than 2-year HOME measures were positively and significantly correlated with instrumental mastery motivation even when controlling for gender, activity level, and DQ.

Conclusion

Mastery motivation had moderate stability during the toddler period. The quality of home environment in infancy appeared to have a significant impact on toddler's mastery motivation. To promote mastery motivation, caregivers should provide better quality of home environment for infants/toddlers during the very early years.
