The relation of spatial skills, spatial memory span, and two anxiety types with statistics anxiety in European and North American University students
BACKGROUND & AIMS: The present two studies investigated the role of spatial cognition in statistics anxiety. The hypothesis that spatial representations and/or visuospatial skills are related to the acquisition of statistics abilities which, when lacking or unused, generate statistics anxiety is examined. MATERIALS & METHODS: To this end, a total of 680 students in Social Sciences from 14 different universities located in one of three countries e…
Exploring Creative Spaces Predict Domain‐Specific Creative Achievements
This study aimed to understand the factors predicting creative activities and creative achievements among university students. Based on a recently proposed framework of 10 creative spaces, we hypothesized that exploring those creative spaces, alongside the personality trait openness to experience and divergent thinking abilities would predict creative activities and achievements in specific domains. Using the Inventory of Creative Activities and …
The Creative Space Theory as a map to explore the mind
Despite significant transformations in most domains of activities, there might still be some constancies in the creative spaces explored throughout history. This paper introduces the Creative Space Theory (CST), a conceptual framework delineating 10 distinct creative spaces, analogous to creative landscapes. These creative spaces are proposed as navigational terrains for an array of media, tools, activities, and domains. The 10 spaces of the theo…
Two case studies of very long-term retention
Here, we present two case studies of extremely long-term retention. In the first, Richard C. Atkinson (RCA) had learned word sequences during experiments for his dissertation. Sixty-seven years later, RCA relearned the same words either in the original order or in a scrambled order. RCA reported no conscious awareness that the words were those used in the dissertation, but his relearning was considerably better for the words in the original order…
Is perfectionism a killer of creative thinking? A test of the model of excellencism and perfectionism
The standards that a person pursue in life can be set in a rigid or flexible way. The recent literature has emphasized a distinction between high and realistic standards of excellence, from high and unrealistic standards of perfection. In two studies, we investigated the role of striving towards excellence (i.e., excellencism) and striving towards perfection (i.e., perfectionism) in relation to divergent thinking, associative thinking, and openne…
The cognitive architecture of processes responsible to assess similarity and clarity in a comparison task
When asked to compare two stimuli, participants are on average faster to respond Same than Different, an effect coined the fast-same. The dual-process theory argues that information about similarity is processed in priority over any other type of information, causing the fast-same effect. We tested this serial architecture of cognitive processes using a double factorial paradigm, suitable for a Systems Factorial Technology (SFT) analysis. Twenty …

An Unbiased Estimate of Global Interrater Agreement
Assessing global interrater agreement is difficult as most published indices are affected by the presence of mixtures of agreements and disagreements. A previously proposed method was shown to be specifically sensitive to global agreement, excluding mixtures, but also negatively biased. Here, we propose two alternatives in an attempt to find what makes such methods so specific. The first method, R B , is found to be unbiased while at the same tim…
Likelihood and its use in Parameter Estimation and Model Comparison
Parameter estimation and model fitting underlie many statistical procedures. Whether the objective is to examine central tendency or the slope of a regression line, an estimation method must be used. Likelihood is the basis for parameter estimation, for determining the best relative fit among several statistical models, and for significance testing. In this review, the concept of Likelihood is explained and applied computation examples are given.…
A Ratio Test of Interrater Agreement With High Specificity
Existing tests of interrater agreements have high statistical power; however, they lack specificity. If the ratings of the two raters do not show agreement but are not random, the current tests, some of which are based on Cohen’s kappa, will often reject the null hypothesis, leading to the wrong conclusion that agreement is present. A new test of interrater agreement, applicable to nominal or ordinal categories, is presented. The test statistic c…
Outliers detection and treatment
Outliers are observations or measures that are suspicious because they are much smaller or much larger than the vast majority of the observations. These observations are problematic because they may not be caused by the mental process under scrutiny or may not reflect the ability under examination. The problem is that a few outliers is sometimes enough to distort the group results (by altering the mean performance, by increasing variability, etc.…
Confidence intervals in within-subject designs
Within-subject ANOVAs are a powerful tool to analyze data because the variance associated to differences between the participants is removed from the analysis. Hence, small differences, when present for most of the participants, can be significant even when the participants are very different from one another. Yet, graphs showing standard error or confidence interval bars are misleading since these bars include the between-subject variability. Lo…
