Gesture Helps,Only If You Need It: Inhibiting Gesture Reduces Tip-of-the-Tongue Resolution for Those With Weak Short-Term Memory

People frequently gesture when a word is on the tip of their tongue (TOT), yet research is mixed as to whether and why gesture aids lexical retrieval. We tested three accounts: the lexical retrieval hypothesis, which predicts that semantically related gestures facilitate successful lexical retrieval; the cognitive load account, which predicts that matching gestures facilitate lexical retrieval only when retrieval is hard, as in the case of a TOT; and the motor movement account, which predicts that any motor movements should support lexical retrieval. In Experiment 1 (a between-subjects study; N = 90), gesture inhibition, but not neck inhibition, affected TOT resolution but not overall lexical retrieval; participants in the gesture-inhibited condition resolved fewer TOTs than participants who were allowed to gesture. When participants could gesture, they produced more representational gestures during resolved than unresolved TOTs, a pattern not observed for meaningless motor movements (e.g., beats). However, the effect of gesture inhibition on TOT resolution was not uniform; some participants resolved many TOTs, while others struggled. In Experiment 2 (a within-subjects study; N = 34), the effect of gesture inhibition was traced to individual differences in verbal, not spatial short-term memory (STM) span; those with weaker verbal STM resolved fewer TOTs when unable to gesture. This relationship between verbal STM and TOT resolution was not observed when participants were allowed to gesture. Taken together, these results fit the cognitive load account; when lexical retrieval is hard, gesture effectively reduces the cognitive load of TOT resolution for those who find the task especially taxing.     

Christian Supersessionism,Zionism, and the Contemporary Scene

Postliberal theology has been a topic of considerable theological debate over the past few decades. In his 2011 book Another Reformation, Peter Ochs deploys a postliberal theological model for the purpose of developing a sophisticated understanding of the future of interreligious relations. Ochs argues that postliberal theology is a reparative theology focusing on alleviating human suffering. He argues that the Christian idea of supersessionism may be the most challenging for Christians to confront as they explore avenues for making interreligious dialogue more effective. Ochs critiques the Mennonite theologian John Howard Yoder's understanding of Zionism as Jewish Constantianism for being an instance of an ostensibly postliberal theology losing its way. In this essay, I offer a critique of Ochs's reading of Yoder, claiming that Yoder's view actually mirrors an important intra‐Jewish debate about the relationship between political power and piety, and retrieves an ingenious contribution of both early Judaism and early Christianity that is effaced in today's growing Constantinian approach to Christian imperialism and Jewish nationalism.
