Longitudinal imaging-based measures of brain structure and function were examined in adult individuals (baseline age, 45-86 years; two to five visits per participant over 1-9 years).

Aesthetic Preference for Glossy Materials: An Attempted Replication and Extension.

The psychology of art and aesthetics has a long-standing interest in how low-level features, such as symmetry, curvature, and color, affect people's aesthetic experience.

Time to Renovate the Humor Styles Questionnaire? An Item Response Theory Analysis of the HSQ.

The Humor Styles Questionnaire (HSQ) is one of the most popular self-report scales in humor research.

Regarding strengths, the analyses found very good evidence for reliability and dimensionality and essentially zero gender-based differential item functioning, indicating no gender bias in the items.
