In 2 recent studies on rats (J. M. Pearce, M. A. Good, P. M. Jones, & A. McGregor, see record 2004-12429-006) and chicks (L. Tommasi & C. Polli, see record 2004-15642-007), the animals were trained to search in 1 corner of a rectilinear space. When tested in transformed spaces of different shapes, the animals still showed systematic choices. Both articles rejected the global matching of shape in favor of local matching processes. The present authors show that although matching by shape congruence is unlikely, matching by the shape parameter of the 1st principal axis can explain all the data. Other shape parameters, such as symmetry axes, may do even better. Animals are likely to use some global matching to constrain and guide the use of local cues; such use keeps local matching processes from exploding in complexity. 相似文献

Previous research has addressed the effects of corporate social responsibility (CSR) initiatives on consumer purchase intention (CPI). However, most of the empirical evidence is based on the analysis of mature large-scale firms; much less examines the effects of CSR initiatives on CPI in entrepreneurial contexts. In this study, we address this gap by investigating whether entrepreneurial start-ups' declaration of CSR engagement affects consumers' purchasing intent. We assert that consumers may consider firms' CSR engagement as a signal for unobserved product quality. We exploit a vignette experimental approach to test our theoretical predictions. In our experiment, participants received online invitations to subscribe to an electronic catalog that advertised various products supplied by entrepreneurial start-ups. The invitations are of five types, some of which presenting different CSR-related information on the suppliers to the participants. Overall, we find that the displayed information on CSR engagement promotes participants' willingness to subscribe to the electronic catalog, indicating that consumers will increase their purchase intentions for ethically oriented suppliers. Moreover, we find that among all the initiatives, external CSR initiatives (social contribution and environmental responsibility) promote consumers' intentions to purchase most effectively. To the best of our knowledge, our study is the first to explore the effects of different CSR initiatives on entrepreneurial start-ups in entrepreneurship literature. We highlight the heterogeneous effects of CSR initiatives on CPI, contributing new insights to research on CSR and consumer behavior. 相似文献

Across three studies, conducted between Spring 2020 and Spring 2021, we tested whether exposure to an Asian American/Pacific Islander (AAPI) target person wearing a face mask would increase or decrease White Americans' perceived threat from and positivity toward AAPI individuals. Although results varied by study, a single-paper meta-analysis revealed that the masked (compared to unmasked) AAPI target resulted in greater positivity toward AAPIs, due to reduced perceptions of both symbolic threat to group values and realistic threat to group health. Positivity toward AAPIs did not reliably differ after exposure to a masked versus unmasked White target. Implications for interventions that encourage COVID-safe behaviors and combat anti-AAPI attitudes are discussed. 相似文献

采用问卷法对454名处于亲密恋爱关系中的未婚个体进行调查,考察了沟通质量在科技侵扰与亲密关系满意度之间的中介效应,及信任对这一中介过程的调节效应。结果表明:(1)科技侵扰对亲密关系满意度具有显著负向预测作用;(2)沟通质量在科技侵扰与亲密关系满意度之间起中介作用;(3)科技侵扰通过沟通质量对亲密关系满意度的中介受到信任的调节,具体来说,个体对伴侣信任水平较高时,将减弱沟通质量变差对亲密关系满意度的破坏作用。本研究在新的时代背景下探究智能手机使用在亲密互动中的影响及其中的机制和边界条件。研究结果提示,科技侵扰可以通过破坏沟通质量影响恋爱个体的亲密关系满意度,且在此过程中信任可以缓冲沟通质量变差对亲密关系的影响。 相似文献

There is increasing evidence of the interconnection between educational and health outcomes. Unfortunately wide disparities exist by both socioeconomic status and race/ethnicity in educational and vocational success. This study sought to promote urban youths’ career readiness as a way to reduce involvement in risk behaviors. Two hundred primarily African‐American youth (ages 14–21) were recruited from a pediatric primary care clinic. Youth randomized to the intervention received three motivational interviewing sessions focused around expectations and planning for the future. Baseline and 6‐month follow‐up assessments included measures of career readiness and risk behavior involvement (i.e., physical fighting, alcohol and marijuana use). At 6‐months, youth randomized to the intervention condition showed increased confidence in their ability to perform the behaviors needed to reach their college/career goals. Additionally, youth randomized to the intervention arm showed decreased fighting behavior (adjusted rate ratio: .27) and marijuana use (adjusted rate ratio: .61). Assisting urban youth in thinking and planning about their future holds promise as a way to reduce their involvement in risk behaviors. This study also demonstrated that motivational interviewing could be used to promote positive behaviors (i.e., career readiness). 相似文献

According to the race models of the stop-signal paradigm, stopping success (successful vs. unsuccessful stopping) is attributed to the finishing times of a go and a stop process. In addition to those factors involving processing times, in the present study we sought to use electrophysiological measures to find factors involving activations that could affect stopping success. We hypothesized that voluntarily-generated unimanual preparation would be a factor. To assess voluntarily-generated unimanual preparation in the stop-signal paradigm, we used a selective-stopping task without any precue. The selective-stopping task also allowed us to assess reaction times (RTs) even when stopping was successful. We demonstrated shorter RTs in signal-respond (i.e. unsuccessful stopping) than in signal-inhibit (successful stopping) trials, as is predicted by the race models. More importantly, we also demonstrated different pre-signal lateralized readiness potentials between the two types of trials and larger lateralized mu ERD in signal-respond than in signal-inhibit trials, suggesting that voluntarily-generated unimanual preparation affects stopping success. In addition to what is described in the race models of the stop-signal paradigm, the present results therefore demonstrated measures of pre-signal activations that could influence stopping success. 相似文献
