Naïve predictions of motion and orientation in mirrors: From what we see to what we expect reflections to do

The study aimed to investigate naïve beliefs regarding the dynamic and static behavior of reflections. In the first three experiments, participants in the study made predictions about the correspondence between real and reflected movements or about the orientation of the reflection of a static object placed in front of a mirror. In Experiments 1 and 2, paper-and-pencil tasks were used and in Experiment 3 participants were asked to make their predictions while imagining that they were facing a mirror. Results revealed that a percentage of undergraduates (ranging from 25% to 35%) were unable to make correct predictions. We classified the errors into types and found that responses either conform to the belief that reflections do the same or that they do the opposite. This suggests an oversimplification of the geometry of mirror reflections in two directions: participants either generalize what they see when movements are parallel to the mirror or what they see when movements are orthogonal to the mirror. Findings from Experiment 4 confirmed that these two expectations fit in with what people perceive in mirrors. Findings from Experiment 5 confirmed that this is also in agreement with the relationship perceived when looking at similar movements and orientations “outside” mirrors.     

What Matters More—Breaking Tradition or Stereotype Content? Envious and Paternalistic Gender Stereotypes and Advertising Effectiveness

The outcomes of 2 experiments investigating the effectiveness of advertisements that use (non)traditional stereotypes of women (Experiment 1) or men (Experiment 2) are reported. Effectiveness of the ads was tested in relation to perceivers' attitudes toward female or male gender roles, respectively. The main finding was that for both male and female versions of the advertisements, the paternalistic ad strategies were more effective than were the envious ones, supporting the predictions of the stereotype content model over the classic prediction of negative effects of nontraditional gender portrayals for advertising effectiveness. Moreover, attitudes toward gender roles played only a limited role in determining ad effectiveness. Theoretical and practical implications are discussed.     

Relationships among higher-order strengths factors,subjective well-being,and general self-efficacy – The case of Israeli adolescents

We investigated relationships among five higher-order strengths factors, subjective well-being, and general self-efficacy in participants that live under challenging conditions. Therefore, a sample of 396 Israeli adolescents (aged 13–18 years) completed the Values in Action Inventory of Strengths for Youth, the Satisfaction With Life Scale, the Affect Balance Scale, and the General Self-Efficacy Scale. An orthogonally rotated principal component analysis of the 24 character strengths yielded five strengths factors that explained 32% of the variance in life satisfaction, with the transcendence strengths factor as the most substantial predictor. The strongest predictors of positive affect were the transcendence and leadership strengths factors; the best predictors of negative affect were the transcendence and temperance strengths factors; and the strongest predictor of affect balance was the transcendence strengths factor. The five strengths factors explained 46% of the variance in general self-efficacy, with the leadership strengths factor as the most substantial predictor. Further analysis indicated that general self-efficacy mediated the relationship between leadership strengths and global life satisfaction. The results suggest that different strengths factors are relevant for different positive experiences (e.g., life satisfaction, self-efficacy beliefs). The findings shed light on the contribution of specific character strengths as a meaningful resource under stressful conditions.     

Addendum to: Heterogeneity Coefficients for Mahalanobis' D as a Multivariate Effect Size

In a previous paper (Del Giudice, 2017 [Heterogeneity coefficients for Mahalanobis' D as a multivariate effect size. Multivariate Behavioral Research, 52, 216–221]), I proposed two heterogeneity coefficients for Mahalanobis' D based on the Gini coefficient, labeled H and EPV. In this addendum I discuss the limitations of the original approach and note that the proposed indices may overestimate heterogeneity under certain conditions. I then describe two revised indices H₂ and EPV₂, and illustrate the difference between the original and revised indices with some real-world data sets.     

Talking at cross-purposes: how Einstein and the logical empiricists never agreed on what they were disagreeing about

By inserting the dialogue between Einstein, Schlick and Reichenbach into a wider network of debates about the epistemology of geometry, this paper shows that not only did Einstein and Logical Empiricists come to disagree about the role, principled or provisional, played by rods and clocks in General Relativity, but also that in their lifelong interchange, they never clearly identified the problem they were discussing. Einstein’s reflections on geometry can be understood only in the context of his ”measuring rod objection” against Weyl. On the contrary, Logical Empiricists, though carefully analyzing the Einstein–Weyl debate, tried to interpret Einstein’s epistemology of geometry as a continuation of the Helmholtz–Poincaré debate by other means. The origin of the misunderstanding, it is argued, should be found in the failed appreciation of the difference between a “Helmholtzian” and a “Riemannian” tradition. The epistemological problems raised by General Relativity are extraneous to the first tradition and can only be understood in the context of the latter, the philosophical significance of which, however, still needs to be fully explored.     

Pure left neglect for Arabic numerals

Arabic numerals are diffused and language-free representations of number magnitude. To be effectively processed, the digits composing Arabic numerals must be spatially arranged along a left-to-right axis. We studied one patient (AK) to show that left neglect, after right hemisphere damage, can selectively impair the computation of the spatial frames underpinning recognition and understanding of Arabic numerals, without impairing the spatial frames for coding alphabetic strings or for coding environmental spatial information. The presence in our brain of these specific and precise spatial frames must be rooted in the paramount importance of Arabic numerals processing in our everyday activities.     

The Mechanisms of Space‐Time Association: Comparing Motor and Perceptual Contributions in Time Reproduction

The spatial‐temporal association indicates that time is represented spatially along a left‐to‐right line. It is unclear whether the spatial‐temporal association is mainly related to a perceptual or a motor component. In addition, the spatial‐temporal association is not consistently found using a time reproduction task. Our rationale for this finding is that, classically, a non‐lateralized button for performing the task has been used. Using two lateralized response buttons, the aim of the study was to find a spatial‐temporal association in a time reproduction task. To account for the perceptual component, reference and target stimuli were presented in different spaces through four experiments. In all experiments, a Spatial‐Temporal Association of Response Codes (STEARC) effect was found and this effect was not modulated by the spatial position of both reference and target stimuli. The results suggested that the spatial‐temporal association was mainly derived from the spatial information provided by response buttons, reflecting a motor but not visuospatial influence.     

Bringing up condom use and using condoms with new sexual partners: Intentional or habitual?

Abstract

A prospective study of 94 Dutch adults who have casual sexual partners examined whether two important aspects of safe sex, namely bringing up condom use (BCU) and actual condom use (ACU) are intentional or habitual. For each of these aspects, a model based on the Theory of Planned Behaviour (TPB: Ajzen, 1991) was pitted against a similar model that was extended with a path from past to later BCU and ACU, respectively. The results suggest that bringing up the issue of condom use was equally predicted by intentions and past BCU. However, among people with casual partners, using condoms - and more importantly not using condoms - was especially predicted by past ACU, suggesting a strong habitual component. These results are discussed in terms of their implications for safe sex education and the use of theories in safe sex promotion campaigns.     

Predictors of reading fluency in Italian orthography: Evidence from a cross-sectional study of primary school students

This study investigates the role of linguistic and visuospatial attentional processes in predicting reading fluency in typical Italian readers attending primary school. Tasks were administered to 651 children with reading fluency z scores > ?1.5 standard deviation to evaluate their phonological awareness, rapid automatized naming (RAN), verbal short-term memory, vocabulary, visual search skills, verbal-visual recall, and visual-spatial attention. Hybrid models combining confirmatory factor analysis and path analysis were used to evaluate the data obtained from younger (first and second grade) and older (third–fifth grade) children, respectively. The results showed that phonological awareness and RAN played a significant role among younger children, while also vocabulary, verbal short-term memory, and visuospatial attention were significant factors among older children.     

Factorial and Construct Validity of FACES IV Among Italian Adolescents

The aims of this study were to evaluate the reliability, validity and factorial structure of Family Adaptability and Cohesion Evaluation Scale, Version IV (FACES IV), investigate the relevance of sex and age on family functioning and study the relationship between family functioning and adolescents’ perception of parent and peer attachment. The sample consisted of 1,416 participants (672 women, 744 men, M_age = 17.38 years; age range = 13–22 years) divided into three age groups: 13–15, 16–18, and 19–22 years. Factor analysis confirmed the dimensions formulated to define the construct of family functioning: all the items of each dimension were loaded in the same factor with a correlation of at least 0.30. Groups differed with regard to the age on Cohesion, Enmeshed and Rigid scales: Younger adolescents (age 13–15 years) showed significantly higher scores than adolescents (age 16–18 and 19–22). Sex differences revealed that females had a higher mean score on Cohesion and Flexibility, whereas males had a higher mean score on Disengaged, Enmeshed and Chaotic. Correlations between FACES IV and Parent and Peer Attachment Scale demonstrated the convergent validity of the FACES IV. Data confirmed the validity of FACES IV’s Italian version and suggested that the Circumplex Model has a cross-cultural applicability and it could be a useful instrument in the Italian context.
