Non‐linear structural equation models with correlated continuous and discrete data

Structural equation models (SEMs) have been widely applied to examine interrelationships among latent and observed variables in social and psychological research. Motivated by the fact that correlated discrete variables are frequently encountered in practical applications, a non‐linear SEM that accommodates covariates, and mixed continuous, ordered, and unordered categorical variables is proposed. Maximum likelihood methods for estimation and model comparison are discussed. One real‐life data set about cardiovascular disease is used to illustrate the methodologies.     

Dynamic Biculturalism: Socially Connected and Individuated Unique Selves in a Globalized World

In an increasingly connected world brought about by globalization, opportunities abound for countries and individuals to become bicultural or multicultural. This paper reviewed experimental studies that were designed to test bicultural Chinese individuals' responsiveness to Chinese and Western culture primes with regard to autobiographical memory, the inclusion of significant others in the self-concept, and how such self-inclusiveness can be revealed by functional magnetic resonance imaging of the bicultural brain. Results showed that across all three areas, bicultural individuals resonated to the specific cultural context by displaying their socially connected or individuated unique self in support the 'alternation' model of biculturalism ( LaFromboise, Coleman, & Gerton, 1993 ) and its underlying dynamism.     

Sex bias in visual images evoked by generics: A new zealand study

Male biases are known to exist in the usage, evaluation, and interpretation of masculine generics. This study explored, by means of a tachistoscope, sex-specific biases in visual images evoked by masculine (All men are created equal, At university a student can study whatever he wants) and feminine (The feminists protested outside the town hall, At university a student can study whatever she wants) generics. Photographs of male and female faces were presented in a deliberately ambiguous (subthreshold) viewing field while maintaining the masculine or feminine generic sentence on constant view. It was predicted and found in a sample of 48 university students that if generics invoked sex-specific images, the images would affect the direction in which the viewer would resolve the ambiguous faces, resulting in more reported male faces in the masculine than in the feminine generic condition.Preparation of this article was supported by a New Zealand Social Sciences Research Fund Committee grant (8632/21/24/8604) to S.

The Effects of Argument Quality and Involvement Type on Attitude Formation and Attitude Change: A Test of Dual‐Process and Social Judgment Predictions

Involvement has long been theoretically specified as a crucial factor determining the persuasive impact of messages. In social judgment theory, ego‐involvement makes people more resistant to persuasion, whereas in dual‐process models, high‐involvement people are susceptible to persuasion when argument quality is high. It is argued that these disparate predictions might be reconciled by either different involvement types (i.e., value relevant vs. outcome relevant) or different attitude modification processes (i.e., attitude change vs. attitude formation). An experiment (N = 684) varying topic, position advocated, outcome relevance, and argument quality tested these moderators. The data were consistent with existence of two different types of involvement, but none of the theoretical predictions were consistent with the data. Instead, a main effect for argument quality had the largest impact on attitude change. Regardless of value‐relevant involvement, outcome‐relevant involvement, and attitude modification process, participants were more persuaded by high‐ rather than low‐quality arguments, with boomerang effects observed for low‐quality arguments. These findings highlight the importance of sound message design in persuasion.     

Impulsivity in internet addiction: a comparison with pathological gambling

Internet addiction has been considered to be associated with poor impulse control. The aim of this study is to compare the trait impulsivity of those suffering from Internet addiction with that of individuals suffering from pathological gambling. Twenty-seven patients diagnosed with Internet addiction (age: 24.78±4.37 years), 27 patients diagnosed with pathological gambling (age: 25.67±3.97 years), and 27 healthy controls (age: 25.33±2.79 years) were enrolled in this study. All patients were men seeking treatment. Trait impulsivity and the severity of the Internet addiction and pathological gambling were measured by the Barratt Impulsiveness Scale-11, the Young's Internet Addiction Test, and the South Oaks Gambling Screen, respectively. The Beck Depression Inventory and the Beck Anxiety Inventory were also administered to all subjects. Our results show that those suffering from Internet addiction showed increased levels of trait impulsivity which were comparable to those of patients diagnosed with pathological gambling. Additionally, the severity of Internet addiction was positively correlated with the level of trait impulsivity in patients with Internet addiction. These results state that Internet addiction can be conceptualized as an impulse control disorder and that trait impulsivity is a marker for vulnerability to Internet addiction.     

Changes in cue-induced, prefrontal cortex activity with video-game play

Brain responses, particularly within the orbitofrontal and cingulate cortices, to Internet video-game cues in college students are similar to those observed in patients with substance dependence in response to the substance-related cues. In this study, we report changes in brain activity between baseline and following 6 weeks of Internet video-game play. We hypothesized that subjects with high levels of self-reported craving for Internet video-game play would be associated with increased activity in the prefrontal cortex, particularly the orbitofrontal and anterior cingulate cortex. Twenty-one healthy university students were recruited. At baseline and after a 6-week period of Internet video-game play, brain activity during presentation of video-game cues was assessed using 3T blood oxygen level dependent functional magnetic resonance imaging. Craving for Internet video-game play was assessed by self-report on a 7-point visual analogue scale following cue presentation. During a standardized 6-week video-game play period, brain activity in the anterior cingulate and orbitofrontal cortex of the excessive Internet game-playing group (EIGP) increased in response to Internet video-game cues. In contrast, activity observed in the general player group (GP) was not changed or decreased. In addition, the change of craving for Internet video games was positively correlated with the change in activity of the anterior cingulate in all subjects. These changes in frontal-lobe activity with extended video-game play may be similar to those observed during the early stages of addiction.     

Creative Personality and Anticreative Environment for High School Dropouts

The study examined the possible roles that creativity plays in students dropping out of high school. It used data from the National Educational Longitudinal Study (NELS: 88), the Educational Longitudinal Study (ELS: 2002), and 87 high school students from a low income area in southeastern Michigan. NELS and ELS questions related to creative personality and anticreative school environment were selected and asked of students. The students’ responses were compared to their scores on measures of creativity (Runco Ideational Behavior Scale, Torrance Tests of Creative Thinking, & Scales for Rating the Behavioral Characteristics of Superior Students). The NELS respondents who showed creative personality were identified and examined whether their creativity related to dropping out. The results of logistic regression analyses indicated that the questions selected from NELS and ELS that showed anticreative school environment have a negative correlation with the scores on the creativity measures, which affect students’ dropping out. An understanding of these students and their behavior will help promote creative students’ academic and lifelong success through appropriate classroom restructuring.     

Personality Traits and Political Participation: Evidence from South Korea

Using a nationally representative survey fielded in 2009, we analyze the relationships between personality traits and various modes of political participation in South Korea. We find statistically significant relationships between personality (measured by the Five‐Factor Model) and several nonelectoral modes of participation. Openness correlates positively with protest participation, rally attendance, financial contributions to political causes, news media contacts, and political activities via the Internet. Agreeableness correlates negatively with these five participation modes as well as petition signing. Conscientiousness is positively associated with individual political acts (e.g., contacting news media and elected officials and donation), while it is negatively associated with collective actions such as participation in rally. However, we do not find any significant relationship between personality and voter turnout. Reflecting an unusually conflictual political climate of South Korea in 2008, we discuss these findings' implications focusing on the personality‐situation interactions.     

Definition of Financial Abuse: A Culture-Centered Construct among Korean Elders

One of the critical issues in addressing financial abuse in Korea is the absence of an appropriate definition voiced by the elderly. This study is designed to explore how Korean elders define financial abuse in given social and cultural contexts. Face-to-face, in-depth interviews were conducted with 124 elders, aged 60 to 79, residing in Korea. The results of qualitative data analysis using grounded theory revealed that a vast majorty of Korean elderly respondents defined financial abuse as lack of provision of financial support to elder parents, and a small portion of respondents defined it as financial exploitation by adult children. The definition of financial abuse reflects cultural beliefs based on filial piety about financial expectations within the parent–child relationship. Education on financial abuse for both elders and their adult children and establishment of income support programs are urgently needed efforts to increase the financial well-being of elderly Koreans.
