Over 60 percent of Americans have some sort of family pet. Although studies have explored the personality and demographic correlates of pet ownership, none have considered whether religious characteristics may influence not only pet ownership, but the kind of pet Americans own. Drawing on data from the 2018 General Social Survey, we examine the religious antecedents of pet ownership in general as well as owning a cat or a dog, taking into account factors previously associated with owning certain pets (e.g., urban vs. rural residence, political affiliation). Although religious tradition and biblical literalism generally do not predict pet ownership, frequent worship attendees and the most conservative evangelicals report owning fewer pets. Religious characteristics also predict Americans’ ownership of particular pets. Most notably, we find a strong, negative association between worship attendance and cat ownership. We theorize potential mechanisms. On the one hand, certain personality types might simultaneously attract some Americans toward religious participation and away from pets, and cats in particular. Alternatively, to the extent that pet ownership is a partial substitute for human bonding and interaction, Americans more deeply embedded within a religious community may have less need (or time) for pets generally, and specifically more independent “roommate pets,” like cats. 相似文献

Researchers have recently begun to evaluate video-based preference assessments; however, only two studies have evaluated the efficacy of this preference assessment modality in assessing preference for social interactions. Four individuals diagnosed with autism spectrum disorder who could not match pictures or graphic-interchange-format images (GIFs) of social interactions to in vivo interaction participated. We compared picture and GIF-based paired-stimulus preference assessments for social interaction and evaluated the preference assessment hierarchies by conducting a concurrent-operant reinforcer assessment including all social interactions. The GIF-based preference assessment produced similar hierarchies to the reinforcer assessment for all participants, whereas the picture-based preference assessments produced similar hierarchies to the reinforcer assessment for 2 of 4 subjects. Additionally, we conducted a modality preference assessment in which we evaluated participants' preference for viewing GIFs or pictures of social interactions, and found that 3 out of 4 subjects displayed a preference for GIFs. 相似文献

Ego Function Assessment was adapted into a self-report inventory yielding 12 operationalized function measures. 426 respondents from a stratified sample completed the inventory. In addition, 42 respondents completed the inventory twice within a 20-day period. A hierarchical algorithm was used to revise the 12 scales to maximize internal consistencies. Their stabilities were assessed by analyzing the retest scores. Standardization, reliability, and stability data are presented for the original and revised scales. Results show adequate reliability, suggesting that the tool may be useful to measure ego functioning in nonclinical populations. 相似文献

This study provides a comprehensive picture of age differences in self-esteem from age 9 to 90 years using cross-sectional data collected from 326,641 individuals over the Internet. Self-esteem levels were high in childhood, dropped during adolescence, rose gradually throughout adulthood, and declined sharply in old age. This trajectory generally held across gender, socioeconomic status, ethnicity, and nationality (U.S. citizens vs. non-U.S. citizens). Overall, these findings support previous research, help clarify inconsistencies in the literature, and document new trends that require further investigation. 相似文献

This paper describes two vignettes from psychoanalytic work with a mother who experienced unusual communication with her baby when they were apart. These episodes suggest there are sensory cues or an extrasensory perceptual awareness between individuals separated by physical distance. This paper attempts to describe these thought transferences in order to better understand communication phenomena that have not been described in the scientific literature. 相似文献

In the present study we made use of Event-Related Potentials (ERPs) to examine raising and subject control constructions in German. Our most salient result is that the ERPs elicited at the empty subject position of a raising construction are clearly different from those elicited at the corresponding position of an otherwise identical subject control construction, the former producing a stronger P600. We argue that this result provides an electrophysiological correlate of the theoretical distinction between NP trace and PRO. 相似文献
