Self-Other Differentiation Scale: Dimensionality,IRT Parameterization,and Measurement Invariance

The Self-Other Differentiation Scale (Olver, Aries, &; Batgos, 1989 Olver, R. R., Aries, E., &; Batgos, J. (1989). Self-other differentiation and the mother-child relationship: The effects of sex and birth order. The Journal of Genetic Psychology, 150, 311–321. doi:10.1080/00221325.1989.9914600[Taylor &; Francis Online] , [Google Scholar]) is a self-report instrument assessing the experience of a separate sense of self from others. The authors aimed to examine its dimensionality, reliability, and measurement invariance across gender. It was completed by 348 participants (48% men) from 17 to 30 years old in Study 1, 348 participants (40% men) from 18 to 28 years old in Study 2, and 1,068 participants (49% men) from 17 to 28 years old in Study 3. The results supported the hypothesis of just one factor underlying the scale; they also showed an appropriate internal consistency and a partial measurement invariance across gender. Results also showed evidence for a 10-item version of the scale. Globally, the Self-Other Differentiation Scale can be considered a good scale to assess individual's sense of differentiation of one's own sense of self from others.     

Cognitive appraisal mediating relationship between social anxiety and internet communication in adolescents

Research suggests that people with high social anxiety trait may be more inclined to interact through computer-mediated communication (CMC). The psychological underpinnings of this inclination however remained unclear. The present research thus examines if cognitive appraisal bias (i.e. heighten estimation of social risk and deflated self-efficacy) would mediate the relationship between social anxiety and one’s perception of CMC attributes, contributing to a differential pattern of responses in CMC use. Four hundred and ten adolescents aged 12-18 years completed a set of self-reported measures tapping social anxiety trait, cognitive appraisals, perception of CMC attributes, and pattern of CMC social responses. Structural equation modeling lent support to the mediating role of the cognitive appraisal factors. Those with higher social anxiety trait would attach higher self-relevance to the CMC attributes, and engage in a more socially-involved pattern of interpersonal responses in CMC. Implications of these findings are discussed.     

The impact of rumination on internal attention switching

The present study explored the nature of attention control problems associated with ruminative traits. Experiment 1 aimed to establish the validity of a modified mental counting task that assesses individuals' ability to switch attention between internal mental representations. Reaction time and brain activity (event related potential; ERP) measures were examined, and results showed that the task was sensitive to internal attention switching effects. Experiment 2 assessed how the relationship between ruminative tendencies and switching performance differs when participants attend to neutral versus affective materials under different mood states. Although reaction-time analysis suggested that both mood condition and stimulus affectivity were not significant in altering this association, ERP analysis suggested otherwise. A significant task type×trait rumination × mood condition effect was found for switch-related ERP responses, whereby high ruminators were found to deploy more neuronal resources when switching affective materials in sad mood state.     

Test-retest reliability and practice effects of the Wechsler Memory Scale-III

Although serial administration of cognitive tests is increasingly common, there is a paucity of research on test-retest reliabilities and practice effects, both of which are important for evaluating changes in functioning. Reliability is generally conceptualized as involving short-lasting changes in performance. However, when repeated testing occurs over a period of years, there will be some longer lasting effects. The implications of these longer lasting effects and practice effects on reliability were examined in the context of repeated administrations of the Wechsler Memory Scale-III in 339 community-dwelling women aged 40-79 years over 2 to 7 years. The results showed that Logical Memory and Verbal Paired Associates subtests were consistently the most reliable subtests across the age cohorts. The magnitude of practice effects varied as a function of subtests and age. The largest practice effects were found in the youngest age cohort, especially on the Faces, Logical Memory, and Verbal Paired Associates subtests.     

Psychometric Properties and Convergent Validity of the Dependency-Oriented and Achievement-Oriented Psychological Control Scale (DAPCS) with Italian Adolescents

This study is aimed to validate the Italian version of the dependency-oriented and achievement-oriented psychological control scale (DAPCS), a self-report questionnaire designed to assess the adolescent’s perception of the two dimensions of psychological control. In Study 1, we assessed factorial validity and reliability of the Italian version of DAPCS with a sample of adolescents. In Study 2, we examined the convergent validity of the Italian version of the DAPCS analyzing the associations between the two domains of psychological control and well-established measures related to them such as strictness/supervision, overprotection, non dependency on parents, and family functioning. Confirmatory factor analyses confirmed the hypothesized two-factor solution of the DAPCS, with a 16 items’ version better fitting the data, for paternal as well as for maternal ratings. High indices of internal consistency indicated that both subscales produced reliable scores. Convergent validity was confirmed by positive associations between the DAPCS’ subscales and measures of strictness and negative associations between the DAPCS’ subscales and measures of global family functioning, both for maternal and paternal ratings. Finally, results evidenced significant effects for adolescents’ and parental gender on achievement-oriented psychological control, with mothers rated higher than fathers by males and fathers rated higher than mothers by females. Overall, the results of these studies indicated that the Italian form of the DAPCS might be a useful instrument to assess the two domain-specific types of parental psychological control among Italian-speaking adolescents.     

Color perception involves color representations firstly at a semantic level and then at a lexical level

Studies and models have suggested that color perception first involves access to semantic representations of color. This result leads to two questions: (1) is knowledge able to influence the perception of color when associated with a color? and (2) can the perception of color really involve only semantic representations? We developed an experiment where participants have to discriminate the color of a patch (yellow vs. green). The target patch is preceded either by a black-and-white line drawing or by a word representing a natural object associated with the same or a different color (banana vs. frog). We expected a priming effect for pictures because, with a 350-ms SOA, they only involve access to semantic representations of color, whereas words seem only elicit an access to lexical representations. As expected, we found a priming effect for pictures, but also for words. Moreover, we found a general slowdown of response times in the word-prime-condition suggesting the need of an additional processing step to produce priming. In a second experiment, we manipulated the SOA in order to preclude a semantic access in the word-prime-condition that could explain the additional step of processing. We also found a priming effect, suggesting that interaction with perception occurs at a lexical level and the additional step occurs at a color perception level. In the discussion, we develop a new model of color perception assuming that color perception involves access to semantic representations and then access to lexical representations.     

The coupling of short sleep duration and high sleep need predicts riskier decision making

Abstract

Objective: To examine how risk-related decision making might be associated with habitual sleep variables, including sleep variability, sleep duration and perceived sleep need in young adults cross-sectionally and longitudinally.

Design: 166 participants completed a 7-day protocol with sleep and risk-related decision-making measures at baseline (T1) and 12 months later (T2).

Results: Habitual short sleep duration (averaging < 6?h nightly) was identified in 11.0% in our sample. After controlling for baseline demographic factors and risk-taking measures, self-reported sleep need at T1 interacted with habitual short sleep in predicting risk taking at follow-up (F_8,139=9.575, adjusted R²=.431, p<.001). T1 greater perceived sleep need predicted more risk taking among short sleepers, but decreased risk taking among normal sleepers at T2. Variable sleep timing was cross-sectionally correlated with making more Risky choices at baseline and fewer Safe choices after loss at follow up.

Conclusions: Young adults with variable sleep timing and those with short sleep duration coupled with high perceived sleep need were more likely to take risks. The moderating effects of perceived sleep need suggest that individual differences may alter the impact of sleep loss and hence should be measured and accounted for in future studies.     

Explaining Black–White differences in homicide victimization

In recent decades, homicide has so truncated life expectancy in the United States that homicide victimization should be considered a public-health problem worthy of addressing via preventive programs and policies. Evidence in the literature roots homicide victimization deep within the social structure, in problematic social inequalities and disadvantages. The evidence suggests homicide victimization is associated with six demographic, social, and lifestyle factors: being male, African-American, young, of low socioeconomic status, without adequate social support, and mentally ill or a substance user. Taking an interdisciplinary approach, this paper outlines theoretical mechanisms leading to racial differences in homicide victimization. It hypothesizes that Black Americans (a) are likelier than Whites to become homicide victims and, if victimized, (b) are likelier to be younger than victimized Whites. To understand these racial differences, the paper examines whether and how multiple disadvantages—at both the macro and micro level—operate against Blacks disproportionately. The paper concludes by noting further research needs and policy implications.     

Music,identity, and musical ethnocentrism of young people in six Asian,Latin American,and Western cultures

Ethnomusicologists and sociologists have extensively discussed the symbolic role of music in the creation, maintenance, and expression of cultural and national identity, while the underlying social psychological processes remain unexplored. We elaborate psychological mechanisms of identity construction and identity expression through culture‐specific music preferences. We propose and test a model linking music preferences to national identity via musical ethnocentrism in six student samples from Brazil, Germany, Hong Kong, Mexico, New Zealand, and the Philippines. In each context, culture‐specific music styles were related to national identity of its listeners and musical ethnocentrism mediated these effects. This paper bridges culture‐specific and universal perspectives on music and identity by examining the underlying psychological processes in Asian, Latin, and Western cultures.
