James Jurin wrote an extended essay on distinct and indistinct vision in 1738. In it, he distinguished between "perfect," "distinct," and "indistinct vision" as perceptual categories, and his meticulous descriptions and analyses of perceptual phenomena contained observations that are akin to crowding. Remaining with the concepts of his day, however, he failed to recognize crowding as separate from spatial resolution. We present quotations from Jurin's essay and place them in the context of the contemporary concerns with visual resolution and crowding.

Recently, John McCaskey (2020) has proposed that the arrival of Daniel Fahrenheit's thermometers precipitated the eighteenth-century conceptual change of temperature. I examine the usage of the temperature term in the Philosophical Transactions for this period, leading from the creation of the Fahrenheit thermometer up to the first employment of numerical temperature within the journal, in which temperature is constituted by a numerical value. I identify four strands linking thermometry and meteorology to temperature's conceptual change: the weather data network of James Jurin; the dissemination and acclaim for Fahrenheit thermometers; a resurgence in the usage of temperature in meteorological writing; and both exploratory usage and a broadening of the term's extent as it realigned to thermometry.

Sexual desire is a complex construct with important implications for sexual functioning and well-being. In this research, we translated the Sexual Desire Inventory (SDI-2), a widely used scale for assessing sexual (desire), into 25 languages from English and used data from the International Sex Survey (ISS) to (a) investigate its psychometric properties (i.e.

The UPPS-P Impulsive Behavior Model and the various psychometric instruments developed and validated based on this model are well established in clinical and research settings. However, evidence regarding the psychometric validity, reliability, and equivalence across multiple countries of residence, languages, or gender identities, including gender-diverse individuals, is lacking to date. Using data from the International Sex Survey ( = 82,243), confirmatory factor analyses and measurement invariance analyses were performed on the preestablished five-factor structure of the 20-item short version of the UPPS-P Impulsive Behavior Scale to examine whether (a) psychometric validity and reliability and (b) psychometric equivalence hold across 34 country-of-residence-related, 22 language-related, and three gender-identity-related groups.
