Cross-cultural adaptation and validation of the Spanish sensory processing sensitivity questionnaire (S-SPSQ)

Sensory Processing Sensitivity (SPS) is a temperament trait rooted in biology, and is distinguished by heightened awareness, emotional responsiveness, and sensitivity to environmental stimuli. In this study, we aimed to enable the assessment of SPS within Spanish-speaking populations. To achieve this, we translated, adapted, and validated the Sensory Processing Sensitivity Questionnaire (SPSQ), which offers a comprehensive evaluation of SPS, encompassing both positive and negative aspects of the trait. Participants were 1,004 (844 females, mean age 37) mainly from Chile (964), and 40 were from other Spanish-speaking regions. Confirmatory factor analysis, utilizing the diagonally weighted least squares method, was applied to validate the internal structure of the Spanish version of the SPSQ (S-SPSQ). Fit indices such as GFI, CFI, TLI, RMSEA, and SRMR were scrutinized. Reliability assessment utilized Cronbach's alpha and McDonald's Omega. Three models were examined: Model I (six factors) displayed robustness, Model II (six factors plus a general factor) did not show substantive improvement, and Model III (Higher Order and Bifactor) excelled in fit while balancing complexity and representation, thus validating the findings of the original SPSQ and indicating similar reliability coefficients. The study offers a balanced perspective on SPS and contributes to cross-cultural validation of an SPS instrument which may facilitate research and guide personalized therapeutic interventions, thus enhancing outcomes for highly sensitive persons.

Individual differences in scientists' aesthetic disposition, aesthetic experiences, and aesthetic sensitivity in scientific work

Introduction

The role of personality in shaping engagement with aesthetics in science has been almost entirely unexplored. Whereas artists and arts settings (e.g., museums) are well-studied from a psychological perspective, the practice of science has often been seen as purely rational or dry. In response, this study presents novel findings on the critical role of scientists' individual differences, which shape their engagement with aesthetics, such as the frequency of their experiences of beauty, wonder, and awe in their scientific work.

Methods

Based on a very large and representative four-country study of scientists in the fields of biology and physics (N = 3,092), this study analyzed the associations of Big Five personality traits among scientists with (i) dispositional aesthetics (DPES-awe), (ii) the frequency of aesthetic experiences in scientific work, and (iii) aesthetic sensitivity in science. These survey-weighted OLS regression models included extensive statistical controls for sociodemographic factors.

Results

As hypothesized, openness is positively, and neuroticism is negatively linked with dispositional aesthetics, the frequency of aesthetic experiences in scientific work, and aesthetic sensitivity in science. Unexpectedly, agreeableness and conscientiousness (but not extraversion) are highly significant and strong predictors of the three trait and state aesthetic engagement variables.

Discussion

The aesthetic engagement and personality framework of this paper is empirically supported and demonstrates the importance of personality types of scientists in the practice of science. The unexpectedly strong association of agreeableness with aesthetic engagement points to the importance of cooperation, collaboration, and communication to maximize scientific creativity.

Differences in regional gray matter volume predict the extent to which openness influences judgments of beauty and pleasantness of interior architectural spaces

Hedonic evaluation of sensory objects varies from person to person. While this variability has been linked to differences in experience, little is known about why stimuli lead to different evaluations in different people. We used linear mixed-effects models to determine the extent to which the openness, contour, and ceiling height of interior spaces influenced the beauty and pleasantness ratings of 18 participants. Then, by analyzing structural brain images acquired for the same group of participants, we asked if any regional gray matter volume (rGMV) covaried with these differences in the extent to which the three features influence beauty and pleasantness ratings. Voxel-based morphometry analysis revealed that the influence of openness on pleasantness ratings correlated with rGMV in the anterior prefrontal cortex (Brodmann area (BA)-10), and the influence of openness on beauty ratings correlated with rGMV in the temporal pole (BA38) and cluster, including the posterior cingulate cortex (BA31) and paracentral lobule (BA5/6). There were no significant correlations involving contour or ceiling height. Our results suggest that regional variance in gray matter volume may play a role in the computation of hedonic valuation and account for differences in the way people weigh certain attributes of interior architectural spaces.

Cross-Cultural Adaptation and Validation of the Highly Sensitive Person Scale to the Adult Spanish Population (HSPS-S)

Purpose

This article describes a cross-cultural adaptation of the Highly Sensitive Person Scale (HSPS) to the adult Spanish population, and psychometric analysis of its validation and reliability.

Methods

Convenience sampling by participant accessibility was used. The original version was adapted culturally and linguistically using the back-translation method, and a pilot study was done with 88 participants. Data processing and analysis was performed with the SPSS v.25 and LISREL v.9.2 statistical packages. The psychometric properties were studied in a sample of 8358 participants using exploratory factor analysis and confirmatory factor analysis, and examining factorial invariance and internal consistency.

Results

The results confirmed a Spanish version with 27 items in five-dimensions: sensitivity to overstimulation (SOS), aesthetic sensitivity (AES), low sensory threshold (LST), fine psychophysiological discrimination (FPD) and harm avoidance (HA). Invariance across gender of this factor structure was demonstrated and reliability indices were good.

Conclusion

These findings demonstrate that the HSPS is an appropriate tool for evaluating high sensitivity in the adult Spanish population.

Commentary on Corradi et al.'s (2019) new conception of aesthetic sensitivity: Is the ability conception dead?

Corradi et al. (British Journal of Psychology, 2019) argue that their new conception of visual aesthetic sensitivity (as responsiveness to aesthetic features in one's preferences) presents several advantages in comparison with the current ability view of aesthetic sensitivity, usually defined as the ability to judge aesthetic stimuli in accordance with standards (The Journal of Psychology, 1964, 57 and 49). Although the measure they propose is interesting and presents advances to the field, we point to important issues. Notably, the authors conveniently base their comparison between the two conceptions on psychometric double standards, discard a century of research on aesthetic sensitivity by focusing on Eysenck's speculations, and disguise an extension of already existing aesthetic preference tests (e.g., The Journal of Psychology, 1952, 33 and 199; Empirical Studies of the Arts, 2005, 23 and 165) as a redefinition of aesthetic sensitivity. We conclude that both aesthetic preference and aesthetic sensitivity research are legitimate objects of study, that the authors present interesting ideas to further the study of aesthetic preferences, but that their approach is not new and that its proposed renaming only adds confusion to the field.

A new conception of visual aesthetic sensitivity

Aesthetic sensitivity has been defined as the ability to recognize and appreciate beauty and compositional excellence, and to judge artistic merit according to standards of aesthetic value. The Visual Aesthetic Sensitivity Test (VAST) has often been used to assess this ability, but recent research has revealed it has several psychometric problems. Such problems are not easily remedied, because they reflect flawed assumptions inherent to the concept of aesthetic sensitivity as traditionally understood, and to the VAST itself. We introduce a new conception of aesthetic sensitivity defined as the extent to which someone's aesthetic valuation is influenced by a given feature. Experiment 1 aimed to characterize aesthetic sensitivity to four prominent features in visual aesthetics: complexity, symmetry, contour, and balance. Experiment 2 aimed to replicate the findings of Experiment 1 and to assess the test-retest reliability of an instrument designed to measure aesthetic sensitivity to these features using an abridged set of stimuli. Our results reveal that people differ remarkably in the extent to which visual features influence their liking, highlighting the crucial role of individual variation when modelling aesthetic preferences. We did not find clear relations between the four measures of aesthetic sensitivity and personality, intelligence, and art interest and knowledge. Finally, our measurement instrument exhibited an adequate-to-good test-retest reliability.
