Reducing the backlash effect: Self‐monitoring and women's promotions

Previous research shows that masculine (agentic) women suffer from a backlash effect in which they are sanctioned for violating the feminine gender role stereotype. We examine the impact of self‐monitoring on the promotion rates of MBA men and women over an 8‐year period following graduation. Results show that women who were more masculine as well as high on self‐monitoring received more promotions, suggesting that self‐monitoring is associated with an absence of backlash effects.     

Using the Interactive Systems Framework to Support a Quality Improvement Approach to Dissemination of Evidence-Based Strategies to Promote Early Detection of Breast Cancer: Planning a Comprehensive Dynamic Trial

Dissemination efforts must optimize interventions for new settings and populations. As such, dissemination research should incorporate principles of quality improvement. Comprehensive Dynamic Trial (CDT) designs examine how information gained during dissemination may be used to modify interventions and improve performance. Although CDT may offer distinct advantages over static designs, organizing the many necessary roles and activities is a significant challenge. In this article, we discuss use of the Interactive Systems Framework for Dissemination and Implementation to systematically implement a CDT. Specifically, we describe “Bronx ACCESS”, a program designed to disseminate evidence‐based strategies to promote adherence to mammography guidelines. In Bronx ACCESS, the Intervention Delivery System will elicit information needed to adapt strategies to specific settings and circumstances. The Intervention Synthesis and Translation System will use this information to test changes to strategies through “embedded experiments”. The Intervention Support System will build local capacities found to be necessary for intervention institutionalization. Simulation modeling will be used to integrate findings across systems. Results will inform on‐going policy debate about interventions needed to promote population‐level screening. More generally, this project is intended to advance understanding of research paradigms necessary to study dissemination.

Practicing Safe Text: the Impact of Texting on Walking Behavior

Sending and receiving text messages on cell phones is increasingly common. Texting while walking or driving, however, increases the likelihood of accidents. One possible cause is that distracted individuals are unable to detect safe opportunities for action. To investigate this, we asked participants to walk through doorways of differing widths while holding or texting on their phone. We measured walking speed, doorway‐to‐shoulder‐width ratio, and the number of bumps into the doorframes. Our results revealed that texters were more cautious than non‐texters; they walked slower and rotated their body through doorways they could have safely walked straight through. There were no significant differences, however, in the number of bumps into the doorframes. If texters in the real world behave like those in our laboratory, then the number of texting‐related accidents reported in other studies might suggest that being overcautious while texting does not actually decrease the likelihood of accidents.

Theory learning as stochastic search in the language of thought

We present an algorithmic model for the development of children's intuitive theories within a hierarchical Bayesian framework, where theories are described as sets of logical laws generated by a probabilistic context-free grammar. We contrast our approach with connectionist and other emergentist approaches to modeling cognitive development. While their subsymbolic representations provide a smooth error surface that supports efficient gradient-based learning, our symbolic representations are better suited to capturing children's intuitive theories but give rise to a harder learning problem, which can only be solved by exploratory search. Our algorithm attempts to discover the theory that best explains a set of observed data by performing stochastic search at two levels of abstraction: an outer loop in the space of theories and an inner loop in the space of explanations or models generated by each theory given a particular dataset. We show that this stochastic search is capable of learning appropriate theories in several everyday domains and discuss its dynamics in the context of empirical studies of children's learning.     

Sublexical and Lexico-Syntactic Factors in Gender Access in Spanish

The influence of sublexical and lexico-syntactic factors during the grammatical gender assignment process in Spanish was studied in two experiments using the gender decision task. In Experiment 1, the regularity of the ending of gender-marked nouns (masculine nouns ended in $-o$ and feminine nouns ended in $-a$ ) and of nouns with gender-correlated but unmarked word-endings (e.g., $-ad$ ) was manipulated. The results showed that regularity affected reaction times and error rates only in the case of gender-marked nouns, suggesting that the mere statistical distribution of a word-ending across genders is not responsible for the regularity effect. In Experiment 2, gender-marked nouns and gender-unmarked nouns were preceded by a masked prime which could be a definite article (which provides information about the gender of the noun) or a possessive pronoun (which does not contain gender information). The presentation of the definite article led to shorter reaction times and less errors only when the word-ending was different from $-o$ or $-a$ . Taken together, these results indicate that gender assignment in Spanish is carried out through different processes depending on the noun ending: gender decisions for gender-marked nouns are based on the gender-to-ending distribution. Meanwhile, gender decisions for unmarked nouns seem to require the retrieval of the corresponding definite grammatical article, regardless of the statistical distribution of the noun ending across genders.     

One and Done? Optimal Decisions From Very Few Samples

In many learning or inference tasks human behavior approximates that of a Bayesian ideal observer, suggesting that, at some level, cognition can be described as Bayesian inference. However, a number of findings have highlighted an intriguing mismatch between human behavior and standard assumptions about optimality: People often appear to make decisions based on just one or a few samples from the appropriate posterior probability distribution, rather than using the full distribution. Although sampling‐based approximations are a common way to implement Bayesian inference, the very limited numbers of samples often used by humans seem insufficient to approximate the required probability distributions very accurately. Here, we consider this discrepancy in the broader framework of statistical decision theory, and ask: If people are making decisions based on samples—but as samples are costly—how many samples should people use to optimize their total expected or worst‐case reward over a large number of decisions? We find that under reasonable assumptions about the time costs of sampling, making many quick but locally suboptimal decisions based on very few samples may be the globally optimal strategy over long periods. These results help to reconcile a large body of work showing sampling‐based or probability matching behavior with the hypothesis that human cognition can be understood in Bayesian terms, and they suggest promising future directions for studies of resource‐constrained cognition.     

Inexact Knowledge without Improbable Knowing

Abstract

In a series of recent papers, Timothy Williamson has argued for the surprising conclusion that there are cases in which you know a proposition in spite of its being overwhelmingly improbable given what you know that you know it. His argument relies on certain formal models of our imprecise knowledge of the values of perceptible and measurable magnitudes. This paper suggests an alternative class of models that do not predict this sort of improbable knowing. I show that such models are motivated by independently plausible principles in the epistemology of perception, the epistemology of estimation, and concerning the connection between knowledge and justified belief.

Abstract

Early childhood deprivation, attachment chaos, repeated medical traumata, and abuse set up neural networks of dread, shame, worthlessness, and hopelessness: the phenomenology of abject experience that resides in implicit memory. Abject interactions with others condense yearning and despair into complex enactments of abject suffering. Working in abject subgroups dilutes the intensity of abject material as ownership of toxic affects is broadened. Affective engagement and a relational perspective facilitate the management and transformation of self-abjection into more optimal relatedness in combined group and individual treatment.
