Body posture and gender impact neural processing of power-related words

Judging others’ power facilitates successful social interaction. Both gender and body posture have been shown to influence judgments of another’s power. However, little is known about how these two cues interact when they conflict or how they influence early processing. The present study investigated this question during very early processing of power-related words using event-related potentials (ERPs). Participants viewed images of women and men in dominant and submissive postures that were quickly followed by dominant or submissive words. Gender and posture both modulated neural responses in the N2 latency range to dominant words, but for submissive words they had little impact. Thus, in the context of dual-processing theories of person perception, information extracted from both behavior (i.e., posture) and from category membership (i.e., gender) are recruited side-by-side to impact word processing.     

Attentional focus affects how events are segmented and updated in narrative reading

Readers generate situation models representing described events, but the nature of these representations may differ depending on the reading goals. We assessed whether instructions to pay attention to different situational dimensions affect how individuals structure their situation models (Exp. 1) and how they update these models when situations change (Exp. 2). In Experiment 1, participants read and segmented narrative texts into events. Some readers were oriented to pay specific attention to characters or space. Sentences containing character or spatial-location changes were perceived as event boundaries—particularly if the reader was oriented to characters or space, respectively. In Experiment 2, participants read narratives and responded to recognition probes throughout the texts. Readers who were oriented to the spatial dimension were more likely to update their situation models at spatial changes; all readers tracked the character dimension. The results from both experiments indicated that attention to individual situational dimensions influences how readers segment and update their situation models. More broadly, the results provide evidence for a global situation model updating mechanism that serves to set up new models at important narrative changes.     

Who Counts as Human? Antecedents to Androcentric Behavior

People view men as typically human, although some conditions may make this more or less likely. Language has been implicated as one factor, with masculine generic language (e.g., he used neutrally) leading to more androcentrism relative to its alternatives. However, the influence of two types of alternatives (e.g., they vs. he or she) remains unclear. The present study asked 297 male and female online participants from the United States to select typical representations of humanity from a set of White and Black male and female faces. The wording for the concept humanity was manipulated to be either a typical member of mankind, a typical human, or a typical man or woman (or woman or man). Overall, participants selected more White targets. Participants also selected more male targets, but the degree to which that was the case was affected by wording and participant’s gender. Participants, particularly male participants, in the mankind and human wording conditions were more likely to select a male target as representative, whereas in the man or woman condition, participants’ choices did not differ from chance. Thus, androcentric thinking may be more mutable than previously surmised, varying by participants’ gender and by context.     

Tracking Privilege‐Preserving Epistemic Pushback in Feminist and Critical Race Philosophy Classes

Classrooms are unlevel knowing fields, contested terrains where knowledge and ignorance are produced and circulate with equal vigor, and where members of dominant groups are accustomed to having an epistemic home‐terrain advantage. My project focuses on one form of resistance that regularly surfaces in discussions with social‐justice content. Privilege‐preserving epistemic pushback is a variety of willful ignorance that many members of dominant groups engage in when asked to consider both the lived and structural injustices that members of marginalized groups experience daily. I argue that this dominant form of resistance is neither an expression of skepticism nor a critical‐thinking practice. I suggest that standard philosophical engagements with these expressions of resistance are incapable of tracking the harms of privilege‐preserving epistemic pushback. I recommend treating this pushback as a “shadow text,” that is, as a text that runs alongside the readings in ways that offer no epistemic friction. I offer this as one critical philosophical practice for making students mindful of the ways they contribute to the circulation of ignorance and epistemic violence during the course of their discussions.     

Good-Enough Representations in Language Comprehension

People comprehend utterances rapidly and without conscious effort. Traditional theories assume that sentence processing is algorithmic and that meaning is derived compositionally. The language processor is believed to generate representations of the linguistic input that are complete, detailed, and accurate. However, recent findings challenge these assumptions. Investigations of the misinterpretation of both garden-path and passive sentences have yielded support for the idea that the meaning people obtain for a sentence is often not a reflection of its true content. Moreover, incorrect interpretations may persist even after syntactic reanalysis has taken place. Our good-enough approach to language comprehension holds that language processing is sometimes only partial and that semantic representations are often incomplete. Future work will elucidate the conditions under which sentence processing is simply good enough.     

Galpha(i2) inhibition of adenylate cyclase regulates presynaptic activity and unmasks cGMP-dependent long-term depression at Schaffer collateral-CA1 hippocampal synapses

Cyclic AMP signaling plays a central role in regulating activity at a number of synapses in the brain. We showed previously that pairing activation of receptors that inhibit adenylate cyclase (AC) and reduce the concentration of cyclic AMP, with elevation of the concentration of cyclic GMP is sufficient to elicit a presynaptically expressed form of LTD at Schaffer collateral-CA1 synapses in the hippocampus. To directly test the role of AC inhibition and G-protein signaling in LTD at these synapses, we utilized transgenic mice that express a mutant, constitutively active inhibitory G protein, Galpha(i2), in principal neurons of the forebrain. Transgene expression of Galpha(i2) markedly enhanced LTD and impaired late-phase LTP at Schaffer collateral synapses, with no associated differences in input/output relations, paired-pulse facilitation, or NMDA receptor-gated conductances. When paired with application of a type V phosphodiesterase inhibitor to elevate the concentration of intracellular cyclic GMP, constitutively active Galpha(i2) expression converted the transient depression normally caused by this treatment to an LTD that persisted after the drug was washed out. Moreover, this effect could be mimicked in control slices by pairing type V phosphodiesterase inhibitor application with application of a PKA inhibitor. Electrophysiological recordings of spontaneous excitatory postsynaptic currents and two-photon visualization of vesicular release using FM1-43 revealed that constitutively active Galpha(i2) tonically reduced basal release probability from the rapidly recycling vesicle pool of Schaffer collateral terminals. Our findings support the hypothesis that inhibitory G-protein signaling acts presynaptically to regulate release, and, when paired with elevations in the concentration of cyclic GMP, converts a transient cyclic GMP-induced depression into a long-lasting decrease in release.     

Book Club Groups to Aid Relational Connection and Trust among Addicted Trauma Survivors

This is a secondary analysis of qualitative data from a literacy study, which examines Book Clubs as a creative approach to engage female addicted trauma survivors in developing psychologically safe, trusting therapeutic relationships. This approach is respectful of the participants’ experiences of relational trauma and diverse cultural contexts, in part because book clubs are ‘normal’ experiences in which the client is better able to have control over the level of vulnerability she engages in within the therapeutic milieu. Themes indicating increasing levels of vulnerability and psychological safety include use of book club discussions to identify with text, plot, or characters; to discuss escape coping and aggressive coping; and to discuss self as a victim and as a survivor.     

Addressing Unintended Consequences of Gender Diversity Interventions on Women’s Sense of Belonging in STEM

Sex Roles - Validated interventions that increase bias literacy (i.e., knowledge of gender bias) and decrease sexism are critical to addressing pervasive gender biases in science, technology,...     

Enhancing frequency recording by developmental disabilities treatment staff

We evaluated a staff training and management package for increasing accuracy of recording frequency of problem behavior in a residential care facility. A multiple baseline design across the first and second work shifts showed that 2 of 8 participants increased their accuracy following in-service training, and all 8 improved during a condition with supervisor presence and feedback. Improvements were maintained when feedback was removed and generalized to activity periods when neither supervisor presence nor feedback was provided. Other staff behavior was not adversely affected by the intervention package.
