The purpose of this research was to undertake some analyses of how the language used in text messaging varies as a function of personality traits and the interpersonal context. After completing personality questionnaires, participants provided their most recent text messages and indicated their relationship with the message recipient on several dimensions. Correlations between Linguistic Inquiry and Word Count (LIWC) categories and personality traits and relationship status were examined. There were significant correlations between certain LIWC categories and extraversion (e.g., personal pronouns), neuroticism (e.g., negative emotion words) and agreeableness (e.g., positive emotion words), suggesting that personality traits are displayed in how one texts. One of the defining features of texting - linguistic alterations (e.g., abbreviations) - varied as a function of both personality traits and relationship status. Overall, the results provide a snapshot of what text messages look like, and how they reflect the texter’s personality and the interpersonal context.  相似文献

This study examines the precursors of violent behavior among urban, racial/ethnic minority adults. Data are from an on-going study of male and female African Americans and Puerto Ricans, interviewed at four time waves, Time 1-Time 4 (T1-T4), from adolescence to adulthood. Structural Equation Modeling was used to analyze the developmental pathways, beginning in mid-adolescence (T1; age = 14.0 years), to violent behavior in adulthood (T4; age = 29.2 years). The variables assessed were: components of externalizing behaviors (i.e., rebelliousness, delinquency; T1, T3); illicit drug use (T2); peer delinquency (T2); perceived neighborhood crime (T4); and violent behavior (T3, T4). Results showed that the participants' externalizing behaviors (rebelliousness and delinquency) were relatively stable from mid-adolescence (T1; age = 14.0 years) to early adulthood (T3; age = 24.4 years). The participants' externalizing behaviors in mid-adolescence also had a direct pathway to peer delinquency in late adolescence (T2; age = 19.1 years). Peer delinquency, in turn, had a direct pathway to the participants' illicit drug use in late adolescence (T2), and to externalizing behaviors in early adulthood (T3). The participants' illicit drug use (T2; age = 19.1 years) had both direct and indirect paths to violent behavior in adulthood (T4). The participants' externalizing behaviors in early adulthood (T3) were linked with violent behavior at T3, and perceived neighborhood crime (T4), both of which had direct pathways to violent behavior in adulthood (T4). The findings suggest developmental periods during which externalizing behaviors, exposure to delinquent peers, illegal drug use, and neighborhood crime could be targeted by prevention and intervention programs in order to reduce violent behavior.  相似文献

Wiium, N. & Aarø, L.E. (2011). Outcome expectations and use of smokeless tobacco (snus): A cross‐sectional study among young Norwegian snus users. Scandinavian Journal of Psychology 52, 64–70. In this study, measures of outcome expectancies related to use of snus (wet snuff) were used to predict reported frequency of snus use. Data stem from a nation‐wide survey in Norway among 16‐ to 20‐year‐olds. Only users of snus were included in the statistical analyses (n = 589). The main outcome measure, frequency of snus use, was measured as a categorical variable – occasional, weekly and daily use. Four dimensions of outcome expectancies (mood regulation, smoking control, weight control and negative health outcomes) were measured and confirmed in a confirmatory factor analysis. Informants tended to believe that snus use is harmful to health, but still they supported the idea of snus as a way to control own cigarette smoking. In a SEM model, two of the four dimensions of outcome expectancies turned out to be particularly significant predictors of frequency of snus use – mood regulation and smoking control. No significant interactions with gender were found. Males scored higher than females on “mood regulation”, and “smoking control”, while females scored higher than males on “negative health outcomes”. If more smokers were convinced that snus use is a less harmful alternative, more of them might start using snus, not only because there is some association between health outcome expectancies and snus use, but also because snus use by many is perceived as a remedy to stop smoking and as a way to gain some of the mood regulation benefits which are usually associated with smoking.  相似文献

The community plays an important role in the success of substance abuse prevention efforts. However, current funding structures and a focus on limited approaches to prevention delivery have created a large gap between what substance abuse prevention professionals practice and what the community at large knows about prevention. The concept of “community” has not always been well‐defined in the field of prevention, and there are few mechanisms to engage grassroots community members in evidence‐based substance abuse prevention. This article explains how Wandersman et al.'s (Am J Community Psychol 41:171–181, 2008) Interactive Systems Framework can be applied to grassroots prevention efforts. The authors describe a Community Prevention Support System that collaborates with the Professional Prevention Support System to promote the adoption of evidence‐based substance abuse prevention practices at the grassroots, community level.

Children's acquisition of tool use abilities is an important part of development but is not yet well understood. This study compares two modes of tool-use learning, observation and individual haptic experience. Two- and 3-year-olds had haptic experience with tools, observed tool use by others, had both haptic and observational experience, or no tool exposure. Their tool choice and use were evaluated across six problem-solving tasks that varied in degree of difficulty. Children learned about tools better by observation than by individual learning through manual exploration. Performance also varied by task difficulty, with more complex tasks proving more difficult. Findings are discussed from cognitive and evolutionary perspectives.  相似文献

Despite empirical support for “Self-control theory” in criminology, there is controversy about how self-control should be operationalized. Working within the framework of “self-control theory,” we investigated if violence and criminal behaviors are associated with nine distinct dimensions of cognitive control in a community sample of young men (n = 654) living in peri-urban townships in South Africa. Cognitive control was assessed using the Behavior Rating Inventory of Executive Function. Multivariate statistical analysis was used, to identify associations between violence and criminality, and deaggregated measures of nine distinct components of cognitive control. Fifteen percent of the sample reported recent violence, 27% had been in physical fights with family/friends in the preceding 6 months, 10% reported being arrested, 4% reported forced sexual contact, and 26% reported intimate partner violence (IPV). Controlling for substance use and sociodemographic variables, contact with the criminal justice system and violence were associated with deficits in all domains of cognitive control. Forced sexual contact was associated with behavioral dysregulation. IPV was associated with behavior dysregulation and executive control dysfunction. Future studies might utilize deaggregated measures of self-control to provide further insight into links between particular components of cognitive control and various forms of offending and violence.  相似文献

The current study had the dual purpose of identifying consequences associated with perfectionistic self-presentation (PSP) and evaluating these factors as mediator of the proposed link between PSP and Problematic use of Internet communicative services (GPIU). The present study hypothesized that a self-presentation style characterized by the need to avoid displaying imperfections is associated with GPIU because communicating online rather than in person affords greater control through the reduction of non-verbal cues and the greater temporal flexibility. A sample of 200 university student participants completed measures assessing PSP, GPIU, and perceived controllable aspects of behaviors associated with relying on computer mediated communications (i.e. managing nonverbal displays and buying more time before having to respond). Structural equation modeling confirmed that those who systematically try to avoid revealing their supposed “less than perfect” behaviors or performance place great emphasis on the reduction of nonverbal cues and the temporal flexibility offered by the computer mediated interactions, which, in turn predicts GPIU levels. The findings are discussed in terms of their implications for GPIU and for the perfectionism social disconnection model.  相似文献

The use of a cell phone while driving has been recognized as a form of distracted driving across the world. Many countries have banned the use of handheld mobile devices while operating motor vehicles. In Canada, all the provinces and territories now ban the use of handheld cell phones while driving. Utilizing the 2011 annual Alberta Survey, this study examined the current prevalence of cell phone use while driving in the province of Alberta. Moreover, this paper investigated the impact of the perception of risk on actual behaviors, and if demographic factors played a role. Our results indicated that despite being cognizant of the risks involved, many Albertans (52%) still use cell phones (45% of cell phone users utilized hands-free devices) while driving. Logistic regression analysis indicated that gender, age, employment status, home ownership, household income, immigrant status, and risk perceptions were significant predictors of cell phone use while driving in the province. These findings imply that the use of cell phones while operating a vehicle remains quite high despite legislative efforts to limit such behavior.  相似文献

This study examined the differences in mental health and substance use by gender and across education levels of 634 American Indians from 4 eastern tribes. Multivariate analysis of variance indicated that men self‐rated significantly better mental health but binge drank and used illicit drugs more often compared with women. Participants with a post–high school degree had significantly better mental health than those without a high school diploma. As education increased, cigarette smoking significantly decreased. Implications for culturally appropriate interventions are discussed. Este estudio examinó las diferencias en salud mental y abuso de sustancias entre distintos sexos y niveles de educación de 634 indios americanos de 4 tribus del este. El análisis multivariante de la varianza indicó que los hombres autoevaluaron su salud mental como significativamente mejor, pero consumían alcohol en exceso y usaban drogas ilícitas con más frecuencia que las mujeres. Los participantes con un grado superior a la enseñanza secundaria tenían una salud mental significativamente mejor que aquellos que no terminaron la enseñanza secundaria. A niveles educativos mayores, la incidencia de fumadores disminuyó significativamente. Se discuten implicaciones para intervenciones culturalmente apropiadas.  相似文献
