The effects of activating a “baby brain” stereotype on pregnant women’s cognitive functioning

Throughout pregnancy and into the immediate postpartum period, women are generally perceived to be incompetent, stressed, and forgetful. However, the neuropsychological “baby brain” literature remains unclear and contradictory. Across two studies, we provide the first experimental tests of whether perceived cognitive impairment in pregnancy can be explained by stereotype threat theory, which proposes that awareness of negative stereotypes about one’s ingroup can harm performance. In Study 1 (N = 364), we tested stereotype threat effects in a 2 (stereotype threat versus no threat) × 3 (pregnant women versus new mothers versus never-pregnant female control) design. We observed a main effect of group on memory performance (pregnant women and new mothers performed worse than controls), but no other main or interactive effects. Study 2 (N = 409) aimed to extend these research questions with mathematics ability, memory, and attention as the dependent variables. Again, we found that a stereotype threat manipulation did not impair pregnant women and new mothers’ cognitive performance, nor was there any interactive effects. Groups also did not differ in their performance. We discuss these results in the context of stereotype threat mechanisms, calling into question whether a stereotype threat paradigm can be applied effectively to pregnancy-related stereotypes. This work has implications for the advancement of stereotype threat as a theory and contributes to the reappraisal of the utility of stereotype threat as a way of understanding how stereotypes affect performance.     

Math Weaknesses in Survivors of Acute Lymphoblastic Leukemia Compared to Healthy Children

Difficulties in math are the most frequently reported area of academic deficit in survivors of acute lymphoblastic leukemia (ALL) and the most frequent academic complaint among parents of ALL survivors. However, previous studies that included measures of math skills have been limited by the use of only a single measure of math skills, most often a measure of written calculations, without any assessment of math reasoning or math application skills. Further, the nature of these math difficulties has not been adequately investigated. The purpose of this study was to examine the performance of ALL survivors using multiple measures of math skills. Performance was compared to a group of healthy controls matched for age and sex as well as to normative levels. Other measures of neuropsychological function were also administered, and the relationships between these measures and the math measures were explored. Converging evidence for math difficulties in ALL survivors compared to healthy controls and normative levels was found. While ALL survivors generally performed within the average range on measures of math skills, math performance was mostly related to memory function and dominant-hand psychomotor speed. By contrast, math performance of healthy children was mostly related to basic reading skills and visual-motor integration. These findings shed light on the nature of math difficulties in ALL survivors and have implications for intervention.     

In search of transfer following cued recall practice: The case of process‐based biology concepts

Previous work has demonstrated that cued recall of a term from a fact yields learning that does not transfer, relative to a restudy control, to recall of another term from the same fact. Here we report six experiments in which a series of manipulations during the initial study and training phases of learning, hypothesized to increase transfer for process‐based biology concepts, were investigated. In Experiments 1 and 2, fill‐in‐the‐blank questions combined with immediate or delayed and repeated correct answer feedback improved learning but not transfer. In Experiments 3 and 4, practice questions that involved recalling process steps, understanding ordinal relationships, or making inferences did not improve transfer. Positive transfer was produced, however, in Experiments 5 and 6 via retrieval–verification–scoring, a new method in which difficult fill‐in‐the‐blank questions were combined with extensive feedback processing. We discuss implications for transfer in both theoretical and applied contexts.     

The Importance of Being Emergent: A Theoretical Exploration of Impression Formation in Novel Social Category Conjunctions

Social category conjunction is a form of multiple categorization involving the combination of two simultaneously salient constituent categories to form a complex category (e.g., female soldier). Research has reliably demonstrated that perceivers often apply emergent traits when forming impressions of novel incongruent social category conjunctions, that is, traits not associated with the simple constituent categories (e.g., Kunda, Miller, & Claire, 1990 ). However, the theoretical literature modeling the mechanisms underlying impression formation in novel social category conjunctions is less well established and inconsistent. In this article, we critically evaluate the current state of empirical research and theory on novel social category conjunction, with particular reference to emergent traits, aiming to provide a more coherent framework for future research and theory. In addition, we seek to emphasize the wider importance of emergent traits, by drawing out links between research and theory on social category conjunctions with broader perspectives of impression formation.
