“…These factor analyses were based on polychoric correlations in the R software (R Core Team, 2013). The R package was chosen due to its flexibility working with dichotomous data (Li, 2008). Exploratory factor analysis was conducted on the 15 items from each construct.…”

This article describes the development and validation of a newly designed instrument for measuring the spatial ability of middle school students (11-13 years old). The design of the Spatial Reasoning Instrument (SRI) is based on three constructs (mental rotation, spatial orientation, and spatial visualization) and is aligned to the type of spatial maneuvers and task representations that middle-school students may encounter in mathematics and Science, Technology, Engineering and Mathematics (STEM)-related subjects. The instrument was administered to 430 students. Initially, a set of 15 items were devised for each of the three spatial constructs and the 45 items were eventually reduced to 30 items on the basis of factor analysis. The three underpinning factors accounted for 43% of variance. An internal reliability value of .845 was obtained. Subsequent Rasch analysis revealed appropriate item difficulty fit across each of the constructs. The three constructs of the SRI correlated significantly with existing well-established psychological instruments: for mental rotation (.71), spatial orientation (.41), and spatial visualization (.66). The psychometric characteristics of SRI substantiate the use of this measurement tool for research and pedagogical purposes.

“…If a person’s ability exceeds the item difficulty, she passes this task with a probability higher than 0.5, relative to the difference in levels and vice versa. We calculated parameter estimates and fit statistics using the open-source statistical language R following the protocol described by Yuelin [48].…”

Preschool Children Fail Primate Prosocial Game Because of Attentional Task Demands

Various nonhuman primate species have been tested with prosocial games (i.e. derivates from dictator games) in order to better understand the evolutionary origin of proactive prosociality in humans. Results of these efforts are mixed, and it is difficult to disentangle true species differences from methodological artifacts. We tested 2- to 5-year-old children with a costly and a cost-free version of a prosocial game that differ with regard to the payoff distribution and are widely used with nonhuman primates. Simultaneously, we assessed the subjects’ level of Theory of Mind understanding. Prosocial behavior was demonstrated with the prosocial game, and did not increase with more advanced Theory of Mind understanding. However, prosocial behavior could only be detected with the costly version of the game, whereas the children failed the cost-free version that is most commonly used with nonhuman primates. A detailed comparison of the children’s behavior in the two versions of the game indicates that the failure was due to higher attentional demands of the cost-free version, rather than to a lack of prosociality per se. Our results thus show (i) that subtle differences in prosociality tasks can substantially bias the outcome and thus prevent meaningful species comparisons, and (ii) that like in nonhuman primates, prosocial behavior in human children does not require advanced Theory of Mind understanding in the present context. However, both developmental and comparative psychology accumulate increasing evidence for the multidimensionality of prosocial behaviors, suggesting that different forms of prosociality are also regulated differentially. For future efforts to understand the evolutionary origin of prosociality it is thus crucial to take this heterogeneity into account.

“…Therefore, we used Rasch analysis to modulate the original NEI VFQ-25 responses. Rasch analysis enables persons and items to be positioned on a linear scale according to estimated item calibration values and visual ability (Li 2006;Andrich 2011). Rasch analysis was performed using a partial credit model for polytomous item responses that were based on conditional maximal likelihood (CML) estimates.…”

Purpose: To identify factors influencing vision-related quality of life (VRQOL) according to glaucoma severity. Methods: A total of 901 patients with varying stages of glaucoma were recruited from the prospectively designed LIGHT (Life Quality of Glaucoma Patients Who Underwent Treatment) study organized by the Korean Glaucoma Society. Participants completed a basic questionnaire collecting socioeconomic status and clinical information, in addition to the 25-item National Eye Institute Visual Function Questionnaire (NEI VFQ-25). Subjects were classified by mean deviation (MD) of integrated binocular visual field (IVF) into mild, moderate and severe damage groups. Factors were evaluated for their influence on VRQOL according to glaucoma severity using univariate and multivariable regression models between Rasch-analysed NEI VFQ-25 subscale scores and different variables. Results: The mild, moderate and severe groups contained 720, 111 and 70 patients, respectively; the mean IVF MD in each group was À1.4, À8.5 and À17.9 dB. Significant differences were observed among the three groups with respect to age, IVF MD, visual acuity (VA), education level, income level, number of glaucoma medications prescribed and follow-up period. The most influential factor associated with VRQOL according to glaucoma severity was VA. The VA of the better eye was much more influential on VRQOL than the VA of the worse eye in the moderate and severe defect groups, and the impact of VA on VRQOL was more prominent in advanced glaucoma. Conclusion: Visual acuity is the most influential factor on VRQOL in patients with glaucoma. Preservation of VA should be strongly prioritized to maintain good VRQOL.
