Three experiments with rats examined the possibility that the cue-consequence specificity effect is not mediated by the conditioning of selective associations, but instead reflects the selective behavioral expression of taste-illness and exteroceptive-shock conditioning. Experiment 1 showed that the selective aversion performance could be obtained despite the use of locomotor withdrawal from the CS as the index of conditioning. Experiment 2 compared the response profiles of animals conditioned with footshock or illness to presentation of a saccharin or noise CS. During the test with the noise CS, lithium-conditioned subjects did not differ from control rats on any of several behavioral categories, but shock-conditioned rats showed high levels of freezing in response to the noise cue. During the saccharin test, lithium-treated rats engaged in behaviors such as chin wiping, head shaking, and gaping; these behaviors were rarely or never seen in shock-conditioned rats or controls, whose behavioral profiles during the saccharin test were almost identical. Experiment 3, using a blocking design, found that a noise-lithium pairing did not attenuate subsequent conditioning of a saline-lithium association, nor did a saccharin-shock pairing interfere with conditioning of a noise-shock association. These results confirm that the cue-consequence specificity effect is mediated by the selective associability of taste with illness and of exteroceptive cues with footshock. 相似文献

Racial reckoning is defined as the subjugation of Black, Indigenous, and people of Color (BIPOC) to racial hierarchies and subordinate groups that influence multiple well-being outcomes throughout the developmental lifespan and across generations. With the two pandemics of racial reckoning and COVID-19 amidst a growing controversial political landscape, topics around civic engagement have been brought to the forefront of community conversation. Discussions surrounding civic engagement must go beyond addressing issues of public concern and examine the vehicle in which civic engagement may be delivered. This is becoming increasingly important as civic engagement is one of the main avenues of social change through individual and collective action, particularly regarding racial reckoning and healthcare disparities highlighted by COVID-19. The paper focuses on civic engagement among ethnic minority youth and young adults. An integrated model of civic engagement was created based off what was learned through this review. This proposed model of civic engagement is meant to be the first step to addressing the gap in civic engagement literature for ethnic minority youth. Weaknesses and future considerations regarding the model will also be discussed, as well as any implications for ethnic minority youth and young adults. 相似文献

We test the hypothesis that COVID-19 vaccine hesitancy is attributable to distrustful complacency—an interactive combination of low concern and low trust. Across two studies, 9,695 respondents from different parts of Britain reported their level of concern about COVID-19, trust in the UK government, and intention to accept or refuse the vaccine. Multilevel regression analysis, controlling for geographic area and relevant demographics, confirmed the predicted interactive effect of concern and trust. Across studies, respondents with both low trust and low concern were 10%–22% more vaccine hesitant than respondents with either high trust or high concern, and 26%–29% more hesitant than respondents with both high trust and high concern. Results hold equally among White, Black, and Muslim respondents, consistent with the view that regardless of mean-level differences, a common process underlies vaccine hesitancy, underlining the importance of tackling distrustful complacency both generally and specifically among unvaccinated individuals and populations. 相似文献

When teaching infants new actions, parents tend to modify their movements. Infants prefer these infant-directed actions (IDAs) over adult-directed actions and learn well from them. Yet, it remains unclear how parents’ action modulations capture infants’ attention. Typically, making movements larger than usual is thought to draw attention. Recent findings, however, suggest that parents might exploit movement variability to highlight actions. We hypothesized that variability in movement amplitude rather than higher amplitude is capturing infants’ attention during IDAs. Using EEG, we measured 15-month-olds’ brain activity while they were observing action demonstrations with normal, high, or variable amplitude movements. Infants’ theta power (4–5 Hz) in fronto-central channels was compared between conditions. Frontal theta was significantly higher, indicating stronger attentional engagement, in the variable compared to the other conditions. Computational modelling showed that infants’ frontal theta power was predicted best by how surprising each movement was. Thus, surprise induced by variability in movements rather than large movements alone engages infants’ attention during IDAs. Infants with higher theta power for variable movements were more likely to perform actions successfully and to explore objects novel in the context of the given goal. This highlights the brain mechanisms by which IDAs enhance infants’ attention, learning, and exploration. 相似文献

Although abortion in China has been legalized for several decades, it is still controversial and the woman and man involved are at risk of being stigmatized. The current research replicated two studies conducted in Italy by investigating how the abortion decision of the woman and man influence received moral outrage, dehumanization, and perceptions of female professional competence. Study 1, which only included female participants, found higher moral outrage toward a woman having an abortion when the pregnancy was depicted as referring to a “child” (vs. “foetus”), and higher dehumanization of the woman in terms of human nature. Study 2, which included both male and female participants, and clarified responsibility for the abortion decision with respect to the woman and the man, revealed higher moral outrage and a reduction in the attribution of human uniqueness to the man, and of human nature to both the woman and the man. Moral outrage mediated dehumanization when participants had low positive attitudes toward abortion in Study 1 and high positive attitudes in Study 2. Both studies showed a negative impact of the decision to have an abortion on the woman's perceived traditional professional competence. The results generally align with the findings from Italy and yield some practical implications on reducing abortion stigma. Future abortion stigma research should consider more gender-related factors. 相似文献

Consumers' increasing use of voice-activated artificial intelligence technologies is stimulating the development of a new line of research in the field of marketing aiming to analyse the branding implications in this innovative experiential context. The spread of so-called name-brand voice assistants (NBVAs) is creating interesting opportunities in terms of brand anthropomorphism. The brand anthropomorphisation strategies adopted by companies are poorly studied in the academic literature, and only one contribution has been made in the experiential field of NBVAs. Therefore, the objective of our work is to begin to fill this gap by investigating the pillars of brand anthropomorphisation strategies (i.e., activities and branding outcomes) in the specific NBVA context by adopting a managerial perspective. Therefore, we followed an exploratory qualitative approach based on in-depth personal interviews with practitioners engaged in these strategies in the automotive sector. The resulting cognitive map reveals the following three levels of strategic pillars: drivers (i.e., designing a human-like brand voice and human-like consumer-brand dialogue), intermediate outcomes (i.e., brand personality and the strength of consumer-brand relationships), and final outcomes (i.e., multidimensional brand loyalty). Our study enriches both the literature concerning brand anthropomorphisation strategies and the nascent stream on NBVAs and provides managerial guidelines in the new in-car NBVA context. 相似文献
