Hermatypic corals flourished on reefs in the Gulf of Mexico (GOM) in the late Pleistocene and early Holocene. Today, many of these relict reefs are mesophotic banks that have unique coral assemblages and provide critical habitat; however, the South Texas Banks (STB) lack quantitative surveys. Therefore, we used a remotely operated vehicle to conduct quantitative surveys of 5 banks: Baker, Aransas, Dream, Blackfish Ridge, and Harte. Coral communities, based on estimated coral densities (colonies/m 2 ), significantly differed among banks for terraces, slopes, and overall (combined terrace and slope) communities for most banks examined. Within banks, terrace and slope communities significantly differed for all banks except Harte. Sea whips were the most abundant group on slopes and terraces of most banks and frequently contributed >50% to community similarities and dissimilarities, whereas sea fans and Antipathes frequently contributed >20%. Total coral abundance was twice as high and sea fans were 7 times more abundant on terraces than slopes. Among-bank differences in coral communities were highly correlated to geographic and geomorphic features, especially to bank area, rugosity, longitude, and number of site components. The drivers of these differences, their effects on ecosystem diversity and function, and the connectivity pathways within and among STB and other GOM banks require further investigation. Nevertheless, the observed diversity in community structure within and among banks should be considered in the development of monitoring, conservation, and management plans of these critical habitats.

Although humor is a universal feature of human communication, people vary widely in how they create and use humor. Guided by a broader model of creative self-beliefs, we developed the Humor Efficacy and Identity Short Scales (HEISS), a pair of 4-item scales measuring humor self-efficacy (confidence beliefs about one’s ability to be funny) and humor identity (the centrality of humor ability to one’s self-concept). Using a large sample of English speakers (n = 1842), an item response theory analysis found a suitable range of item difficulty, good item discrimination, and essentially zero gender-based differential item functioning. Follow-up samples with English (n= 304) and Polish (n = 385) speakers found conceptually consistent relationships with humor backgrounds and experiences (e.g., taking classes and holding jobs involving humor) and with Big 5 personality traits. Taken together, these scales show promise for research on people’s humor self-concepts and for studies of gendered aspects of humor use, creation, and appreciation.

Research on everyday creativity—the “little c” creative activities people do in their everyday lives—commonly uses self-report scales to assess people’s engagement in different activities. The present research presents a detailed psychometric analysis of the Biographical Inventory of Creative Behaviors (BICB), a 34-item yes/no checklist of common creative activities that has become one of the most popular self-report measures of everyday creative behaviors. Based on a sample of 2,359 adults, the reliability, dimensionality, item fit, item difficulty, and test information were evaluated from a Rasch model perspective. Overall, the BICB shows good evidence for score reliability and appears essentially unidimensional; a small cluster of misfitting and locally dependent items were flagged for impairing unidimensionality. The items’ difficulty level was generally moderate and suitable for the scale’s intended populations and purposes. Differential item functioning (DIF) based on gender and age, estimated via Rasch tree recursive partitioning methods, found notable gender-based DIF (generally reflecting culturally gendered qualities of some creative activities) but little age-based DIF. Taken together, the BICB has many psychometric strengths. Some opportunities for future scale refinement are discussed.

The Humor Styles Questionnaire (HSQ) is one of the most popular self-report scales in humor research. The present research conducted a forward-looking psychometric analysis grounded in Rasch and item response theory models, which have not been applied to the HSQ thus far. 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. Regarding opportunities for future development, the analyses suggested that (1) the 7-point rating scale performs poorly relative to a 5-point scale; (2) the affiliative subscale is far too easy to endorse and much easier than the other subscales; (3) the four subscales show problematic variation in their readability and proportion of reverse-scored items; and (4) a handful of items with poor discrimination and high local dependence are easy targets for scale revision. Taken together, the findings suggest that the HSQ, as it nears the two-decade mark, has many strengths but would benefit from light remodeling.
