Social comparison processes can affect academic and interpersonal outcomes for minoritized college students. However, the literature has not addressed how these processes play out for Hispanic students who attend Hispanic Majority Institutions, in which Hispanic students comprise more than 50% of the population. In this study, such students ( N = 1...
Background
Lab manuals help researchers and students share a common understanding of the rules, guidelines, and expectations related to being involved with a research laboratory. However, no formal guidelines direct the creation of lab manuals in psychology.
Objective
In this study, we conducted qualitative analyses of 10 psychology lab manuals to...
This paper describes the types of social comparison used by Hispanic students at a Hispanic Majority Institution through two studies (N = 406). We found that students engaged in upward identification more often than downward identification, downward contrast, and upward contrast. However, when comparing themselves on an academic measure, downward i...
This review summarizes the available literature on the knowledge of reproduction in white whales or belugas (Delphinapterus leucas). We discuss reproductive anatomy, physiology, endocrinology, and behavior prior to conception. Following a description of these basic reproductive parameters for each sex, the review describes the mating system of belu...
Non-conceptive sexual behavior (NCSB) is phylogenetically widespread, having been documented in 35 of the 87 extant cetacean species, but function and form of NCSB have not been studied in comparative manner. Many cetacean species engage in NCSB across a wide variety of settings and contexts (e.g., play, sexual, affiliative). NCSB includes both soc...
A number of odontocete species have been cared for by humans for multiple decades, including but not limited to pilot whales, killer whales, Commerson’s dolphins, bottlenose dolphins (Indo-Pacific and common), and beluga whales (or white whales). Because many of these were breeding, numerous reproductive behaviors have been observed, documented, an...
Belugas (Delphinapterus leucas) engage in many forms of play (e.g., object, water, locomotor), but no play is quite as curious as the unusual form of cooperative social play involving mouth-to-mouth interactions. These playful interactions are characterized by two belugas approaching each other head-to-head and interlocking their jaws, clasping one...
Although observed in animals from various taxa, object play is not well studied. While studying object play in managed care belugas (Delphinapterus leucas), we noticed that, in some cases, the belugas self-handicap their play. For example, a beluga may push a ball onto a ledge, so that the object can only be reached by the beluga beaching itself. S...
While the ontogeny of beluga (Delphinapterus leucas) socio-sexual behavior has been documented in animals between 37-and 108-months-old, the first 36 months of life are yet to be examined. This study investigated how socio-sexual behaviors emerge over the first three years of life in a group of belugas in managed care. The emergence of socio-sexual...
The majority of cetacean research suggests a right side/left cerebral hemisphere bias for processing visuospatial information and a left side/right cerebral hemisphere bias for processing social information. Beluga (Delphinapterus leucas) socio-sexual behavior involves motor skills coordination and is also hypothesized to serve a social function. T...
Test anxiety is common and may lead to a range of negative outcomes, including poor exam performance. Therefore, it is important to explore psychological predictors of test anxiety. In this paper, we examined whether intellectual humility can predict test anxiety. In Study 1, college students ( N = 181) completed an intellectual humility measure wi...
Research on college student stress has typically focused on institutions where the student population is predominately White and continuing-generation. This study explored student stress in a unique context—a public regional university where the majority of students are Latinx, first-generation (FGCS), and of low socioeconomic status (SES). Of the...
Belugas (Delphinapterus leucas) in managed care have been reported to show seasonal variation in socio-sexual behaviour, hormone levels and respiration rates; however, little is known about the social interactions of wild belugas when they are not in summer, near-shore congregations. To better understand if belugas show seasonal variation in social...
Intra-specific aggression is not frequently observed in wild cetaceans, including belugas. One proxy, identified in past research, that indicates past aggressive behaviour is the presence of rake marks (scars left on skin by the teeth of conspecifics). Behavioural observations of belugas, compared to bottlenose dolphins, suggest that belugas engage...
Laterality of eye use has been increasingly studied in cetaceans. Research supports that many cetacean species keep prey on the right side while feeding and preferentially view unfamiliar objects with the right eye. In contrast, the left eye has been used more by calves while in close proximity to their mothers. Despite some discrepancies across an...
We contest publication of Marino et al. regarding captive killer whale (Orcinus orca) welfare because of misrepresentations of available data and the use of citations that do not support assertions. Marino et al. misrepresent stress response concepts and erroneously cite studies, which appear to support Marino et al.’s philosophical beliefs regardi...
Although a catalog of beluga socio-sexual behavior has been established, to date, little is known about the development of beluga (Delphinapterus leucas) socio-sexual behavior. The present study explored how socio-sexual behavior developed in belugas under human care by recording the behavior of 5 belugas between years 4 and 10 of life. Overall, th...
Marine mammal welfare has most frequently been a topic of discussion in reference to captive ani-mals. However, humans have altered the marine environment in such dramatic and varied ways that the welfare of wild marine mammals is also important to consider as most current publications regarding anthropogenic impacts focus on popu-lation-level effe...
Conservation leader and humanitarian who made several ground breaking discoveries on chimpanzee behavior in Tanzania and is a current advocate for animal welfare around the world.
Dolphins are frequently described as curious animals; however, there have been few systematic investigations of how dolphins behave when they are curious and the extent to which individual differences in curiosity exist in dolphins. Previous research has described individual differences in dolphins’ frequency of interactions with environmental enri...
Personality has now been studied in species as diverse as chimpanzees and cuttlefish, but marine mammals remain vastly underrepresented in this area. A broad range of traits have been assessed only once in each of bottlenose dolphins and California sea lions, while consistent individual differences in a few specific behaviors have been identified i...
Personality psychology has traditionally focused on the study of individual differences in human cognition and behavior. More recently, the topic of individual differences in nonhuman animal behavior has featured more prominently in biology and psychology research. The study of individual differences in nonhuman animals has important implications f...
Marine mammal behavior and cognition researchers often face a number of challenges, including the research subjects’ lack of interest and verbal abilities, as well as choosing a paradigm with appropriate stimuli for the subjects’ perceptual and cognitive abilities. Researchers who work with human infants often encounter similar challenges when stud...
