Cross-cultural validation of the positivity-scale in five European countries

The aim of the present paper was to test the cross-cultural validity of the Positivity-Scale (P-Scale), a new questionnaire designed for the measurement of positivity (i.e., general tendency to evaluate self, life, and future in a positive way). Participants (N = 3544) from Italy, Germany, Spain, Poland, and Serbia answered eight items of the P-Scale and responded to items from other well-validated measures. Confirmatory Factor Analysis supported the assumed one-factor structure of the P-Scale and demonstrated its gender invariance in each country and cross-cultural validity. Correlation analyses revealed significant and positive associations of the P-Scale with self-esteem, life satisfaction, optimism, and a latent factor variable of positivity, and a negative relation to depression. The findings provided support for the convergent validity of the P-Scale across countries. Possible applications of the P-Scale are suggested. Implications for further research on conditions and outcomes of positivity in different cultural contexts are discussed.     

Are there gender differences in cognitive reflection? Invariance and differences related to mathematics

ABSTRACT

Cognitive reflection is recognized as an important skill, which is necessary for making advantageous decisions. Even though gender differences in the Cognitive Reflection test (CRT) appear to be robust across multiple studies, little research has examined the source of the gender gap in performance. In Study 1, we tested the invariance of the scale across genders. In Study 2, we investigated the role of math anxiety, mathematical reasoning, and gender in CRT performance. The results attested the measurement equivalence of the Cognitive Reflection Test – Long (CRT- L), when administered to male and female students. Additionally, the results of the mediation analysis showed an indirect effect of gender on CRT-L performance through mathematical reasoning and math anxiety. The direct effect of gender was no longer statistically significant after accounting for the other variables. The current findings suggest that cognitive reflection is affected by numerical skills and related feelings.     

Factors associated with cyclists’ self-reported choice of lane position

Riders cycling on roads without bicycle lanes are generally advised to ride in the centre of their lane (primary position), and to move toward the left of the lane (in left-hand traffic; secondary position) only to let faster traffic pass and when it is safe. The present research investigated which situational and personal characteristics were associated with choice of lane position, and whether choice of lane position is associated with on-road crash involvement. A large cohort of bicycle riders from New South Wales Australia reported on their cycling patterns and crashes in 6 reporting weeks over a 1-year period using on-line surveys. During one reporting week 1525 participants identified their preferred choice of lane position in each of 6 visually-depicted scenarios that were designed to investigate the influence of number of lanes (in the cyclists’ direction of travel), parked cars, and bus lanes. A majority of respondents preferred the secondary position in scenarios with a clear kerbside lane. Respondents were significantly more likely to choose the primary position in multiple-lane situations compared to single-lane situations, if there were parked cars in the kerbside lane, and if they were female, younger, experienced riders, transport riders, or high intensity riders. Controlling for personal characteristics, choosing the primary position in a single clear traffic lane scenario was associated with a higher on-road crash rate, while choosing the primary position in a traffic lane with parked cars scenario was associated with a lower on-road crash rate. Results suggested that when riding on-road the bicycle riders in this Australian cohort prefer to keep their distance from motorised traffic, allowing traffic to pass safely when space allows. Nonetheless, results suggested that choice of lane position is highly dependent on the local road and traffic environment. Further research is needed to support advice to cyclists.     

编码方式与指拼特征在聋生手语词加工中的作用研究

本研究探讨了聋生在加工手语词过程中不同编码方式和指拼特征的影响。实验1采用指拼类手语词和手势类手语词考察了指拼有无对手语词编码方式的影响。实验2则采用不同特征的指拼类手语词,深入考察指拼位置、指拼形式对手语词编码方式的影响。结果表明,聋生较语音编码更擅长使用指拼编码加工手语词;指拼与手势的加工存在显著差异,指拼在聋生手语词加工中起到了促进作用;指拼位置与指拼形式共同作用于手语词的加工过程。     

The Multigroup Ethnic Identity Measure – Revised (MEIM-R): Psychometric evaluation with adolescents from diverse ethnocultural groups in Italy

The Multigroup Ethnic Identity Measure – Revised (MEIM-R) is an extensively used questionnaire assessing ethnic identity. However, studies on its measurement characteristics in the European context are lacking. The current study addressed this gap by investigating the MEIM-R psychometric proprieties across multiple ethnocultural groups in Italy. Participants were 1445 adolescents (13–18 years) of Italian, East European, and North African origin. Results showed that the MEIM-R has good internal consistency. Multigroup confirmatory factor analyses revealed configural and metric invariance, i.e., an equal, correlated two-factor structure (ethnic identity exploration and commitment) and equal factor loadings across groups. Scalar invariance, i.e., equal item intercepts, was found only for the commitment scores that showed no group differences in latent factor mean levels. Partial structural invariance was evidenced, with the factor covariances varying across groups. These findings suggest that the MEIM-R is a valuable tool to assess the correlates of ethnic identity, although further research is needed.     

Protecting Women from the Negative Effects of Body Dissatisfaction: The Role of Differentiation of Self

ABSTRACT

Body dissatisfaction is a prevalent and concerning issue among college age women. Due to its strong association with eating pathology, identification of moderating variables is a crucial line of inquiry. The present study investigated the ability for an intrapersonal differentiation-of-self variable (“I” position) to attenuate the impact of body dissatisfaction on anorexia and bulimia symptoms among college women participants. Study findings indicated that an “I” position moderated the body dissatisfaction-bulimia relationship and the body dissatisfaction-anorexia relationship. These findings signified the protective influence of a high “I” position for women with high levels of body dissatisfaction. Research and therapeutic implications are discussed.     

Can spatialisation be extended to episodic memory and open sets?

The SPoARC effect (Spatial Positional Associated Response Codes) has only been observed in working memory (WM) using closed sets. It is interpreted as showing that individuals spatialise to-be-remembered items in a left-to-right fashion, using spatialisation as context. Given that context is crucial for episodic memory (EM), we tested if this effect could be observed in EM by using 15-word lists taken from an open set. After each list, 30 probes were sequentially displayed to test recognition. The left/right-hand key assignment for yes/no answers was varied. No SPoARC effect was observed. However, as all previous SPoARC experiments had used short lists and closed sets, it was not possible to know if this absence of SPoARC was due to the open set feature or the length of the lists. A second experiment was thus run using open sets and short 5-word lists, which do not necessitate EM to be remembered. A SPoARC effect was observed indicating that Experiment 1 result was due to the involvement of supra-span lists and that SPoARC effects do not extend to EM with open sets. Experiment 2 also enabled us to generalise the SPoARC effect to open sets in WM for the first time.     

No Relationship Between Joint Position Sense and Force Sense at the Shoulder

In practice, a single test is used to quantify an individual's proprioception. Previous studies have not found a correlation between joint position sense (JPS) and force sense (FS), which are submodalities of proprioception. The purpose of the present study is to determine if root mean square (RMS) error in JPS and FS are related at the shoulder, controlling for external load and elevation angle. Active shoulder angle and force reproduction protocols were performed. No correlation was found between JPS and FS (r = –.019, p = .941) nor were any individual angle and load combinations significant. The main effect for angle in JPS was significant (p < .001). Follow-up contrast demonstrated a significant (p < .001) decrease in RMS error with increased elevation. A significant load by angle interaction was found for FS (p = .014). Follow-up simple effects tests by angle demonstrated RMS error decreased with load at 50° and 70° but not at 90°. By load, RMS error only decreased for 120% between 50° and 90°. JPS and FS demonstrate different behavior with load and angle. This differing behavior is more likely responsible for the lack of correlation than angle and load differences in JPS and FS protocols.
