Prior research has shown that females are less field independent (FI) than males. However, when gender identity is salient, performance on tests assessing constructs similar to FI may be hindered, because of stereotype threat. This study examined the impact of stereotype threat on gender differences in FI. We expected that (a) reporting one's own gender prior to FI testing and (b) having an opposite-gender experimenter would activate stereotype threat, and in turn result in lower performance on a test of FI among females. Overall, 170 participants were randomly assigned to one of eight conditions in a between-participants design varying the participant's gender, experimenter's gender and timing of the gender question (before vs. after test). Results showed that reporting one's gender before the FI test led to lower FI performance among females. Furthermore, females achieved higher FI when experimenters were females and gender questions were administered after the FI test.
Distraction embedded in working memory tasks leads to impaired performance. This impairment is mitigated when targets and distractors that follow them share common features-a signature effect of interference by superposition. Here we propose that target-distractor similarity modulates not only forgetting from working memory but also encoding into long-term memory. In five experiments, we test this elaboration-by-superposition hypothesis, demonstrating that semantic relatedness between targets and distractors benefits delayed category-cued recall performance (Experiments 1a and 1b), which is not due to carry-over effects from working memory testing (Experiment 2). Just as in the case of working memory, this long-term memory effect is reduced when distractors precede targets (Experiment 3). Finally, we show that while high target-distractor similarity reduces forgetting from working memory, it produces net benefits for long-term memory performance (Experiment 4). Together, the results suggest that common mechanisms underlie encoding into working and long-term memory, and that bindings between features of spatiotemporal context and features of to-be-remembered items play a crucial role.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
