Sexual coercion is receiving much attention with the #MeToo movement. Not all of the tactics that perpetrators use to coerce sex are perceived to be equally unacceptable. This study examined factors that may mitigate negative perceptions, including features of the perpetrator's tactics (verbal vs. physical tactics, relationship‐focused vs. self‐focused reasons to coerce sex) and raters' own current relationship (commitment, dependence, sexually coercive experiences). College women (N = 498) rated whether the perpetrator's behavior was acceptable, was excusable, and would adversely affect a relationship. Verbal (vs. physical) coercion, dependence on a current partner, and sexually coercive experiences in a current relationship mitigated negative perceptions. However, participant ratings were not influenced by the perpetrator's use of relationship‐focused reasons for coercing sex (vs. self‐focused reasons), suggesting that women may resist male attempts to sugar‐coat sexual coercion.  相似文献

Communal predators may often need to make especially intricate foraging decisions, as a predator's success may depend on the actions of its neighbours. Here,we consider the decisions made by Portia africana, a jumping spider (Salticidae) that preys on other spiders, including Oecobius amboseli (Oecobiidae), a small prey spider that lives under small sheets of silk (nests) on the walls of buildings. P. africana juveniles settle near oecobiid nests and then ambush oecobiids as they leave or enter the nest. Two or more P. africana juveniles sometimes settle at the same nest and, when an oecobiid is captured, the P. africana juveniles may share the meal. We investigated the joining decisions made by na?ve P. africana juveniles. Experiments were based on using lures (dead spiders positioned in lifelike posture) arranged in a series of 17 different scenes defined by the presence/absence of a nest, the lure types present and the configuration of the lures and the nest. Our findings imply that P. africana juveniles make remarkably precise predatory decisions, with the variables that matter including whether a nest is present, the identity of spiders inside and outside a nest and how spiders are positioned relative to each other and the nest.  相似文献

Predators everywhere impose strong selection pressures on the morphology and behavior of their prey, but the resulting antipredator adaptations vary greatly among species. Studies of adaptive coloration in prey species have generally focused on cryptic or aposematic prey, with little consideration of color patterns in palatable mobile prey. Complex color patterns have been proposed to decrease the ability of visual predators to capture moving prey (motion dazzle effect). Most support for this hypothesis, however, comes from experiments with human subjects and simulated prey. We tested the motion dazzle effect using, for the first time, natural predators (cane toads, Rhinella marina) and live prey (house crickets, Acheta domesticus) with altered color patterns. We found no support for the motion dazzle effect as striped crickets did not fare better than solid colored ones. Crickets that spent more time moving, however, were more likely to be eaten. Our results suggest that motion specialized visual predators such as toads overcome the motion dazzle effect and impose stronger selection pressure on prey behavior than on coloration. These findings emphasize the importance of sensory specializations of predators in mediating antipredator strategies.  相似文献

This study extends the methodological and theoretical understanding of executive functions (EFs) in preschoolers from low‐ and middle‐income countries (LMIC). First, the authors describe a rigorous process of adapting and evaluating six EF tasks to produce a culturally and developmentally appropriate measure of emerging EFs in a large sample of at‐risk children in rural Pakistan. Next, the authors identify critical developmental and family factors that relate to preschoolers’ EFs over the first 4 years of life. Direct assessment of children's general cognitive skills at age two showed developmental continuity with EFs at age four, and these early cognitive skills mediated the effect of an antecedent parenting intervention on EFs as well as associations of targeted individual and family factors with EFs. Furthermore, directly assessed maternal cognitive capacities and observed maternal scaffolding uniquely predicted EFs in preschoolers. This study is also the first to demonstrate a significant overlap between direct assessments of IQ and EFs in young children from LMIC. Children's general intelligence mediated the associations of EFs with antecedent physical growth and cognitive skills as well as concurrent family factors (maternal verbal intelligence, maternal scaffolding, and home stimulation). After controlling for shared variance between preschoolers’ general intelligence and EFs, three factors emerged as unique predictors of EFs: exposure to an early parenting intervention, physical growth status at age two, and number of older siblings. The findings have important implications for the design of interventions that aim to improve EFs in young children in LMIC.

The authors propose specific temporal profiles that reflect certainty versus doubt about where a partner stands with respect to a dating relationship over time. Two multiwave longitudinal studies focused on within-participant changes in perceived partner commitment. Results from multilevel modeling indicate that individuals whose perceptions of partner commitment fluctuate over time were more likely to be in a relationship that eventually ended than were individuals whose perceptions remained relatively steady. For individuals in recently initiated relationships, the association of fluctuation in perceived partner commitment with later breakup was significant regardless of the initial level of perceived partner commitment or the trend, and for all participants, it remained significant when initial level, trend over time, and fluctuation over time of other meaningful variables were controlled.  相似文献

Acculturation has been associated with decreased physical activity among immigrants. This study assessed the process of changing physical activity patterns within the context of Latin American immigrant women’s migration experiences to Canada. Using the ecological model of health promotion, we applied a mixed methods research design. Thirty-six Latin American immigrant women, 18 recent (<10 years in Canada) and 18 non-recent (>10 years in Canada), participated. Six focus groups and 14 in-depth individual interviews were conducted. The Godin Leisure-Time Exercise Questionnaire was administered. Overall, 86 % of the participants reported gaining weight since coming to Canada. Participants reported becoming more sedentary upon arriving in Canada. Only 27.3 % of recent and 41.7 % of non-recent immigrant women were considered sufficiently physically active. Lack of time, resources, social support, and migration stress were identified as key barriers to physical activity. Migration stress associated with social integration barriers strongly influence physical activity among Latin American immigrant women.  相似文献

Funeral rituals perform important social functions for families and communities, but little is known about the motives of people planning funerals. Using mixed methods, we examine funeral planning as end-of-life relational spending. We identify how relational motives drive and manifest in funeral planning, even when the primary recipient of goods and services is dead. Qualitative interviews with consumers who had planned pre-COVID funerals (N = 15) reveal a caring orientation drives funeral decision-making for loved ones and for self-planned funerals. Caring practices manifest in three forms: (a) balancing preferences between the planner, deceased, and surviving family; (b) making personal sacrifices; and (c) spending amount (Study 1). Archival funeral contract data (N = 385) reveal supporting quantitative evidence of caring-driven funeral spending. Planners spend more on funerals for others and underspend on their own funerals (Study 2). Preregistered experiments (N = 1,906) addressing selection bias replicate these results and find generalization across different funding sources (planner-funded, other-funded, and insurance; Studies 3A–3C). The findings elucidate a ubiquitous, emotional, and financially consequential decision process at the end of life.  相似文献

Research suggests that promoting adaptive approaches to learning early in childhood may help close the gap between advantaged and disadvantaged children. Recent research has identified specific child-level and classroom-level variables that are significantly associated with preschoolers' approaches to learning. However, further research is needed to understand the interactive effects of these variables and determine whether classroom-level variables buffer the detrimental effects of child-level risk variables. Using a largely urban and minority sample (N = 275) of preschool children, the present study examined the additive and interactive effects of children's context-specific problem behaviors and classroom process quality dimensions on children's approaches to learning. Teachers rated children's problem behavior and approaches to learning and independent assessors conducted classroom observations to assess process quality. Problem behaviors in structured learning situations and in peer and teacher interactions were found to negatively predict variance in approaches to learning. Classroom process quality domains did not independently predict variance in approaches to learning. Nonetheless, classroom process quality played an important role in these associations; high emotional support buffered the detrimental effects of problem behavior, whereas high instructional support exacerbated them. The findings of this study have important implications for classroom practices aimed at helping children who exhibit problem behaviors.  相似文献

This paper describes the Spanish adaptation of PACE—Parenting Our Children to Excellence. Successfully offered in preschools and daycare centers since 2002, PACE is a research-based preventive intervention to support families in their parenting task through discussions and activities that address practical childrearing issues and promote child coping-competence. Developed in response to community calls, the new program is known as CANNE –Criando a Nuestros Niños hacia el Éxito. The paper makes the processes linking original and adapted versions explicit by accounting for the conceptual and practical decisions that were made as CANNE was being developed. We begin by summarizing the challenges of adapting and translating a behavioral intervention, and by describing the coping-competence model that informs both versions of the program. We turn then to a detailed account of the adaptation itself and of its results. Specifically, we describe: (a) the consultation process at the origin of this adaptation, (b) the adaptation of the manual and the steps taken to establish the extent to which the English and Spanish versions correspond (adaptation fidelity), and (c) the translation of the manual and the cross-language comparison of measures to demonstrate that they yield comparable data when administered in English and Spanish.  相似文献
