Failure of serial taste-taste compound presentations to produce overshadowing of extinction of conditioned taste aversion

Two experiments were conducted to study overshadowing of extinction in a conditioned taste aversion preparation. In both experiments, aversive conditioning with sucrose was followed by extinction treatment with either sucrose alone or in compound with another taste, citric acid. Experiment 1 employed a simultaneous compound extinction treatment and found results indicative of overshadowing of extinction. By contrast, Experiment 2, in which extinction treatment involved serial compound presentations, failed to obtain evidence of overshadowing of extinction. The results of Experiment 2 indicate that the serial presentation of two tastes was processed as equivalent to the separate presentation of the tastes. The results are discussed in relation to: (1) Convergent evidence from research on latent inhibition, (2) competing theories of learning and, (3) their possible adaptive value in food-selection learning.     

个体对不同社会阶层的内隐公平偏见及态度

考察个体对不同社会阶层的公平偏见及内隐态度,对社会治理和发展具有重要意义。采用内隐联想测验（IAT）对上述问题进行了探讨,结果发现,相对于低社会阶层,个体更易将公平性词汇与高社会阶层相联结（实验1）;也更易将积极性词汇与高社会阶层相联结（实验2）。上述结果表明,个体存在社会阶层偏好,对高社会阶层持有一种更加公平的、积极的内隐认知。     

Missing

Wartime experience in Britain during World War Two left thousands of empty spaces where once buildings and streets had been. It simultaneously left gaps in families, often with far-reaching consequences. In this paper, I reflect on one such case in my own family. I examine how the devastating loss of a particular family member as a consequence of an unlucky combination of time and place played into a silent history of earlier losses connected to physical migration, experiences which had traumatic impact decades later. The interweaving of physical place, space, and gaps, with their emotional and unconscious counterparts is explored in a narrative which also traces their ripple effect through time. As part of this meditation on my family's history, I draw on research on the impact later in life of early childhood experience of maternal depression, and on studies concerning the emotional impact of migration.     

Behavioural interventions for micro-mobility adoption: Low-hanging fruits or hard nuts to crack?

This study explores the potential and challenges of applying behavioural interventions to promote micro-mobility adoption. Our online experiments with New York City residents showed that nudges and faming improved respondents’ willingness to adopt e-scooters significantly. Moreover, our experiments spanned over the pre-, during- and post- COVID-19 lockdown period in New York City. Findings from this natural experiment revealed that the effect of these behavioural interventions varied significantly during the pandemic, likely due to a heightened level of health consciousness and a new perspective regarding social interactions. Behavioural tools cannot be taken off-the-shelf and applied as a blanket policy. Individual and group characteristics have to be assessed to devise the pre-eminent behavioural interventions for a particular target audience. More experiments across a wide range of economic, social, cultural, and political settings are needed to guide the application of behavioural interventions in transportation studies.
