Firms routinely offer warranties, often as attempts to differentiate their offerings from those of competitors. Despite this practice common to virtually every consumer durable category, extant research has been inconclusive regarding the effect of warranties on quality judgments. One potential limitation of these prior investigations is the failure to model a key element of a product warranty—consumer‐side transaction costs associated with warranty redemption. In this article, we introduce the role of consumer‐side transaction costs associated with warranty redemption and examine the joint impact of warranty length and warranty redemption costs for brand names of varying strength on consumers’ judgments of product quality. Two experiments show that warranty length signals security but not quality, and that perceived quality increases as consumers’ warranty redemption costs decrease, provided that the warranty length is short. Different dimensions or aspects of warranties have different effects on perceived quality. The implications of the results for understanding conflicting findings in the warranty‐quality literature are discussed. 相似文献
Family communication is essential for accurate cancer risk assessment and counseling; family blockers play a role in this
communication process. This qualitative analysis of social exchanges is an extension of earlier work characterizing those
who are perceived by study participants as health information gatherers, disseminators, and blockers within families with
Hereditary Breast and Ovarian Cancer (HBOC) susceptibility. Eighty-nine women, ages 23–56 years, enrolled in a Breast Imaging
Study (BIS) and participated in a sub-study utilizing a social assessment tool known as the Colored Ecological Genetic Relational
Map (CEGRM). Purposive sampling ensured that participants varied according to numbers of participating family members e.g., ranging from 1 to 6. Eighty-nine women from 42 families (1–8 relatives/family) participated. They collectively designated
65 blockers, both male and female. Situational factors, beliefs, attitudes and cultural traditions, privacy and protectiveness
comprised perceived reasons for blocking intra-family health communications. Longitudinal data collected over 4 years showed
families where blocking behavior was universally recognized and stable over time, as well as other families where blocking
was less consistent. Self-blocking was observed among a significant minority of participating women. Blocking of health communications
among family members with HBOC was variable, complex, and multifaceted. The reasons for blocking were heterogeneous; duration
of the blocking appeared to depend on the reasons for blocking. Blocking often seemed to involve bi-directional feedback loops,
in keeping with Lepore’s Social Constraints and Modulation Theory. Privacy and protectiveness predominated as explanations
for long-term blocking. 相似文献
A growing body of evidence suggests that a wide range of animals can recognize and respond appropriately to calls produced
by other species. Social learning has been implicated as a possible mechanism by which heterospecific call recognition might
develop. To examine whether familiarity and/or shared vulnerability with the calling species might influence the ability of
sympatric species to distinguish heterospecific alarm calls, we tested whether four ungulate species (impala: Aepyceros melampus; tsessebe: Damaliscus lunatus; zebra: Equus burchelli; wildebeest: Connochaetes taurinus) could distinguish baboon (Papio hamadryas ursinus) alarm calls from other loud baboon calls produced during intra-specific aggressive interactions (‘contest’ calls). Overall,
subjects’ responses were stronger following playback of alarm calls than contest calls. Of the species tested, impala showed
the strongest responses and the greatest difference in composite response scores, suggesting they were best able to differentiate
call types. Compared with the other ungulate species, impala are the most frequent associates of baboons. Moreover, like baboons,
they are susceptible to both lion and leopard attacks, whereas leopards rarely take the larger ungulates. Although it seems
possible that high rates of association and/or shared vulnerability may influence impala’s greater ability to distinguish
among baboon call types, our results point to a stronger influence of familiarity. Ours is the first study to compare such
abilities among several community members with variable natural histories, and we discuss future experiments that would more
systematically examine development of these skills in young ungulates. 相似文献
There are data that show that women are objectified in the media, that girls and women experience a high rate of body dissatisfaction and eating problems, and that exposure to objectified media images of women is related to the experience of self-objectification and body shame among women. Media images of women promote a thin, sexy ideal. The objectification of men in the media has increased, perhaps promoting a “drive for muscularity” among boys. In the present study grade-school girls and boys ages 6 through 12 were shown four pictures of objectified images of women and men, respectively, and asked about their responses to the pictures. Although girls and boys responded equally positively to the objectified images of the people of their gender, girls showed a more consistent response to the pictures. Further, there were stronger relationships between girls' responses to the pictures, awareness and internalization of media images, and body esteem. Girls who consistently showed a rejection response to the pictures had higher body esteem than those girls who were uncertain about how to respond to the pictures. It was concluded that, perhaps due to cultural images and cultural pressures, girls more readily develop a consistent response to objectified images of women (than boys do to objectified images of men) that relates to their feelings about their own bodies. 相似文献
Difficulty engaging families in mental health treatment is seen as an underlying reason for the disparity between child mental health need and service use. Interpretation of the literature on how best to engage families is complicated by a diversity of operational definitions of engagement outcomes and related interventions. Thus, we sought to review studies of engagement interventions using a structured methodology allowing for an aggregate summary of the most common practices associated with effective engagement interventions. We identified 344 articles through a combination of database search methods and recommendations from engagement research experts; 38 articles describing 40 studies met our inclusion criteria. Following coding methods described by Chorpita and Daleiden (J Consul Clin Psychol 77(3):566–579, 2009, doi:10.1037/a0014565), we identified 22 engagement practice elements from 89 study groups that examined or implemented family engagement strategies. Most frequently identified engagement practice elements included assessment, accessibility promotion, psychoeducation about services, homework assignment, and appointment reminders. Assessment and accessibility promotion were two practice elements present in at least 50 % of treatment groups that outperformed a control group in a randomized controlled trial. With the exception of appointment reminders, these frequently identified engagement practice elements had a high likelihood of being associated with winning treatments when they were used. This approach offers a novel way of summarizing the engagement literature and provides the foundation for enhancing clinical decision-making around treatment engagement. 相似文献
Previous research has demonstrated that rats will increase their rates of lever pressing for sucrose rewards in the first
half of an experimental session when food pellets, rather than the same sucrose, continually serve as the reward in the second
half of the session. This effect has been coined induction, and the present study investigated whether it could be altered
by altering "motivational" variables. Experiment 1 manipulated subjects' motivation by altering, across conditions, their
level of food deprivation. Predictably, the size of induction varied directly with level of deprivation. Experiments 2 and
3 manipulated subjects' motivation by feeding them food pellets and sucrose, respectively, prior to their responding in the
experimental session. These pre-session feedings decreased the size of the observed induction in both experiments. The results
from the present study indicate that the size of induction is correlated with subjects' motivation to respond for the available
reinforcers. They are also consistent with the idea that operant processes underlie the effect. The notion that induction
might encompass the concept of "anticipation" is also discussed.

The present study evaluated the effects of two reinforcement contingencies on teacher use of behavior-specific praise (BSP) in the classroom. An alternating treatments design was used to compare the implementation of both an independent and interdependent contingency to increase frequency of BSP delivery. Four general education elementary school teachers and their students participated. Teachers’ use of BSP and general praise, as well as, behavior-specific and general reprimands were evaluated. Data were also collected on students’ levels of academically engaged and disruptive behaviors. Both the independent and interdependent conditions resulted in higher frequencies of BSP and reduced the use of both general and behavior-specific reprimands. Student levels of academic engagement increased while disruption decreased across both contingencies. Results of the present study are discussed in terms of related literature and implications for applied practice.
Emotions are highly influential to many psychological processes. Indeed, research employing emotional stimuli is rapidly escalating across the field of psychology. However, challenges remain regarding discrete evocation of frequently co-elicited emotions such as amusement and happiness, or anger and disgust. Further, as much contemporary work in emotion employs college students, we sought to additionally evaluate the efficacy of film clips to discretely elicit these more challenging emotions in a young adult population using an online medium. The internet is an important tool for investigating responses to emotional stimuli, but validations of emotionally evocative film clips across laboratory and web-based settings are limited in the literature. An additional obstacle is identifying stimuli amidst the numerous film clip validation studies. During our investigation, we recognized the lack of a categorical database to facilitate rapid identification of useful film clips for individual researchers’ unique investigations. Consequently, here we also sought to produce the first compilation of such stimuli into an accessible and comprehensive catalog. We based our catalog upon prior work as well as our own, and identified 24 articles and 295 film clips from four decades of research. We present information on the validation of these clips in addition to our own research validating six clips using online administration settings. The results of our search in the literature and our own study are presented in tables designed to facilitate and improve a selection of highly valid film stimuli for future research. 相似文献
Problematic drinking has long been established as an important antecedent to the perpetration of intimate partner violence (IPV). As little research has evaluated individual differences beyond anger in this association, this research examines problematic drinking and IPV perpetration through the lens of self-determination theory (SDT), the relational perspective suggesting individuals are motivated to be in their relationship for autonomous (i.e., self-driven) and controlled (i.e., guilt-driven) reasons. We test the hypothesis that problematic drinking is more strongly associated with IPV among those who are controlled in their motivation in four independent samples (N?=?617). College students in relationships completed measures of alcohol consumption, negative alcohol-related consequences, relationship motivation, and IPV perpetration. Results generally suggested that the association between both alcohol consumption and negative alcohol-related consequences and IPV perpetration is only significant among those endorsing greater controlled motivation. This study supports problematic drinking as not being an equal risk factor for all individuals, and suggests that some people may be more vulnerable to problematic drinking resulting in relationship aggression. 相似文献
