Factorial invariance and latent mean differences of scores on trait emotional intelligence across gender and age

Little is known about the factorial invariance and latent mean difference across sex and age in trait emotional intelligence (EI). The purpose of this study was to examine whether the measurement structure underlying trait EI is equivalent across sex and age groups. The sample consisted of 2919 teenagers, youths and adults. In order to investigate the above hypothesis the measurement and structural equivalence as well as the equality of latent means of scores across sex and age were tested. The multi-group confirmatory factor analysis results revealed that configural, metric, scalar and structural invariance exist across sex and age samples. Findings regarding the latent mean differences across sex and age groups are discussed with reference to recent and past findings.     

Bodies and occlusion: Item types,cognitive processes,and gender differences in mental rotation

The aim of the current study was to reexamine previous findings in which the magnitude of the male advantage in mental rotation abilities increased when participants mentally rotated occluded versus nonoccluded items and decreased when participants mentally rotated human figures versus blocks. Mainly, the study aimed to address methodological issues noted on previous human figure mental rotations tests as the items composed of blocks and human body were probably not equivalent in terms of their cognitive requirements. Our results did not support previous research on embodied cognition as mental rotation performance decreased among both men and women when mentally rotating human figures compared to block items. However, for women, the effect of occlusion was decreased when mentally rotating human figures. Results are discussed in terms of task difficulty and gender differences in confidence and guessing behaviour.     

Latent inhibition in within-subject designs: The roles of masking, schizotypy, and gender

Latent inhibition (LI) is defined as poorer associative learning with a previously exposed, irrelevant stimulus than with a non-preexposed, novel stimulus. This study examined how type of within-subject procedure, class of schizotypal symptoms, and gender modulate LI. Two within-subject procedures were examined, one excluding, and one including a masking task. The former yielded a stronger stimulus preexposure effect than the latter. However, the stimulus preexposure effect was attenuated by total schizotypy score in the masked, but not in the non-masked procedure. The results with schizotypy factors (positive and negative symptoms) as well as with schizotypy factors × gender interactions were inconsistent with those of other studies. It was suggested that in addition to LI, interference and novel pop-out effects were also produced by the procedures, particularly in the non-masked condition.     

Individual differences in spatial relation processing: effects of strategy, ability, and gender

Numerous studies have focused on the distinction between categorical and coordinate spatial relations. Categorical relations are propositional and abstract, and often related to a left hemisphere advantage. Coordinate relations specify the metric information of the relative locations of objects, and can be linked to right hemisphere processing. Yet, not all studies have reported such a clear double dissociation; in particular the categorical left hemisphere advantage is not always reported. In the current study we investigated whether verbal and spatial strategies, verbal and spatial cognitive abilities, and gender could account for the discrepancies observed in hemispheric lateralization of spatial relations. Seventy-five participants performed two visual half field, match-to-sample tasks (Van der Ham, van Wezel, Oleksiak, & Postma, 2007; Van der Ham, Raemaekers, van Wezel, Oleksiak, and Postma, 2009) to study the lateralization of categorical and coordinate relation processing. For each participant we determined the strategy they used in each of the two tasks. Consistent with previous findings, we found an overall categorical left hemisphere advantage and coordinate right hemisphere advantage. The lateralization pattern was affected selectively by the degree to which participants used a spatial strategy and by none of the other variables (i.e., verbal strategy, cognitive abilities, and gender). Critically, the categorical left hemisphere advantage was observed only for participants that relied strongly on a spatial strategy. This result is another piece of evidence that categorical spatial relation processing relies on spatial and not verbal processes.     

The Peer Interaction in Primary School Questionnaire: testing for measurement equivalence and latent mean differences in bullying between gender in Egypt,Saudi Arabia and the USA

The Peer Interaction in Primary School Questionnaire (PIPSQ) was developed to assess individuals’ levels of bullying and victimization. This study used the approach of latent means analysis (LMA) within the framework of structural equation modeling (SEM) to explore the factor structure and gender differences associated with the PIPSQ in a sample of Egyptian (N = 361), Saudi Arabian (N = 350) and USA (270) children. Results of the confirmatory factor analysis are consistent with previous work and support the cross-cultural validity of the PIPSQ factor structure. The PIPSQ factor loadings were invariant across Egyptian and Saudi samples, whereas only partial invariance was met between Egyptian or Saudi samples and the USA sample. Full measurement invariance was met between gender within the three cultures, that is the PIPSQ was useful to compare bullying and victims between gender within the three cultures, but it is only valid to compare those two constructs between Egyptian and Saudi boys and girls. The results indicated that Egyptian and Saudi boys/girls had a higher level of bullying than American boys/girls, whereas no differences were displayed among the three cultures on the victimization subscale. Boys had a higher level of bullying than girls in the three cultures, and boys and girls had a similar level of victimization in three cultures.     

Felt obligations to reciprocate to an employer,preferences for mobility across employers,and gender: Three-way interaction effects on subsequent voice behavior

Previous research suggests that employees engage in voice behavior to reciprocate for the positive treatment they receive from employers, but less is known about individual differences in employees' willingness to engage in voice behavior to that end. The present study proposes that felt obligations to the organization relate more strongly to voice behavior when employees also have stronger preferences for job stability (rather than job mobility). We also propose that this two-way interaction will be further moderated by gender; specifically, males who feel strong obligations to reciprocate and have strong preferences for job stability are especially likely to engage in voice behavior. Data collected from 209 employees over an 8-month period support both the proposed two-way and three-way interaction effects. Thus, while the norm of reciprocity is widely held, the effects of felt obligations to employers on voice behavior also depend upon both gender differences and individual differences in preferences for job stability.
