How crucial is the response format for the testing effect?

Combining study and test trials during learning is more beneficial for long-term retention than repeated study without testing (i.e., the testing effect). Less is known about the relative efficacy of different response formats during testing. We tested the hypothesis that overt testing (typing responses on a keyboard) during a practice phase benefits later memory more than covert testing (only pressing a button to indicate successful retrieval). In Experiment 1, three groups learned 40 word pairs either by repeatedly studying them, by studying and overtly testing them, or by studying and covertly testing them. In Experiment 2, only the two testing conditions were manipulated in a within-subjects design. In both experiments, participants received cued recall tests after a short (~19 min) and a long (1 week) retention interval. In Experiment 1, all groups performed equally well at the short retention interval. The overt testing group reliably outperformed the repeated study group after 1 week, whereas the covert testing group performed insignificantly different from both these groups. Hence, the testing effect was demonstrated for overt, but failed to show for covert testing. In Experiment 2, overtly tested items were better and more quickly retrieved than those covertly tested. Further, this does not seem to be due to any differences in retrieval effort during learning. To conclude, overt testing was more beneficial for later retention than covert testing, but the effect size was small. Possible explanations are discussed.     

“A new and modern golden age of Jewish culture”: shaping the cultural politics of transnational Jewish antifascism

The Holocaust and a worldwide Jewish enthusiasm and support for the Red Army’s defeat of the German Army on the Eastern Front led to a greater sense of international Jewish consciousness and solidarity often tied to an antifascist politics. Utilizing a transnational lens, I explore how Jewish antifascists of the immediate post-war period proffered a novel cultural politics as a means of addressing ongoing international issues of post-Holocaust Jewish survival in a dangerous and politically uncertain modernity. I examine three Jewish left magazines of the late 1940s that were involved in a loose international antifascist progressive Jewish network and ideological framework. These magazines Jewish Life (USA), New Life (UK) and Unity (Australia) represented similar antifascist politics and cultural outlooks in the USA, Britain and Australia, respectively. They have received little sustained scholarly attention previously. I analyse their vision of diverse multilingual Jewish cultures which were to be promoted and developed in any country where Jews lived and in whatever language they spoke. Their cultural vision represented antifascist values against bourgeois or nationalist Jewish culture and broadly reflected a pro-Soviet, progressive and Jewish internationalist, Popular Front politics and worldview.     

Monitor yourself! Deficient error-related brain activity predicts real-life self-control failures

Despite their immense relevance, the neurocognitive mechanisms underlying real-life self-control failures (SCFs) are insufficiently understood. Whereas previous studies have shown that SCFs were associated with decreased activity in the right inferior frontal gyrus (rIFG; a region involved in cognitive control), here we consider the possibility that the reduced implementation of cognitive control in individuals with low self-control may be due to impaired performance monitoring. Following a brain-as-predictor approach, we combined experience sampling of daily SCFs with functional magnetic resonance imaging (fMRI) in a Stroop task. In our sample of 118 participants, proneness to SCF was reliably predicted by low error-related activation of a performance-monitoring network (comprising anterior mid-cingulate cortex, presupplementary motor area, and anterior insula), low posterror rIFG activation, and reduced posterror slowing. Remarkably, these neural and behavioral measures predicted variability in SCFs beyond what was predicted by self-reported trait self-control. These results suggest that real-life SCFs may result from deficient performance monitoring, leading to reduced recruitment of cognitive control after responses that conflict with superordinate goals.     

When misconduct goes unnoticed: The acceptability of gradual erosion in others’ unethical behavior

Four laboratory studies show that people are more likely to accept others’ unethical behavior when ethical degradation occurs slowly rather than in one abrupt shift. Participants served in the role of watchdogs charged with catching instances of cheating. The watchdogs in our studies were less likely to criticize the actions of others when their behavior eroded gradually, over time, rather than in one abrupt shift. We refer to this phenomenon as the slippery-slope effect. Our studies also demonstrate that at least part of this effect can be attributed to implicit biases that result in a failure to notice ethical erosion when it occurs slowly. Broadly, our studies provide evidence as to when and why people accept cheating by others and examine the conditions under which the slippery-slope effect occurs.
