Short theta burst stimulation to left frontal cortex prior to encoding enhances subsequent recognition memory

Deep semantic encoding of verbal stimuli can aid in later successful retrieval of those stimuli from long-term episodic memory. Evidence from numerous neuropsychological and neuroimaging experiments demonstrate regions in left prefrontal cortex, including left dorsolateral prefrontal cortex (DLPFC), are important for processes related to encoding. Here, we investigated the relationship between left DLPFC activity during encoding and successful subsequent memory with transcranial magnetic stimulation (TMS). In a pair of experiments using a 2-session within-subjects design, we stimulated either left DLPFC or a control region (Vertex) with a single 2-s train of short theta burst stimulation (sTBS) during a semantic encoding task and then gave participants a recognition memory test. We found that subsequent memory was enhanced on the day left DLPFC was stimulated, relative to the day Vertex was stimulated, and that DLPFC stimulation also increased participants’ confidence in their decisions during the recognition task. We also explored the time course of how long the effects of sTBS persisted. Our data suggest 2 s of sTBS to left DLPFC is capable of enhancing subsequent memory for items encoded up to 15 s following stimulation. Collectively, these data demonstrate sTBS is capable of enhancing long-term memory and provide evidence that TBS protocols are a potentially powerful tool for modulating cognitive function.

The two‐sided nature of individual and intragroup experiences in the aftermath of collective victimization: Findings from four diaspora groups

Most social psychological research on collective victimhood has examined its consequences for intergroup relations. Less attention has been paid to individual and intragroup processes associated with collective victimization, which the present study aimed to examine. We conducted eight focus group interviews among four diaspora communities (Armenian Americans, Burundian refugees, Jewish Americans, Nepali‐speaking Bhutanese refugees) with historical or more recent experiences of collective victimization. Thematic analysis revealed three major foci shared across communities (but with different emphases within each focus), which included juxtaposed themes that highlight the two‐sided nature of experiencing and coping with collective victimization and its aftermath: Vulnerability and struggle versus resilience and strength, loss versus continuity and renewal, and silence about versus transmission of knowledge about ingroup victimization. These findings illustrate how groups integrate seemingly opposite poles of collective victimization that characterize this complex and multifaceted experience, which has important theoretical implications.     

Feminism,Capitalism, and Ecology

This article critically assesses the different ways of theoretically connecting feminism, capitalism, and ecology. I take the existing tradition of socialist ecofeminism as my starting point and outline two different ways that the connections among capitalism, the subordination of women, and the destruction of the environment have been made in this literature: materialist ecofeminism and Marxist ecofeminism. I will demonstrate the political and theoretical advantages of these positions in comparison to some of the earlier forms of theorizing the relationship between women and nature, but I will also submit them to philosophical critique. I will show how the Marxist ecofeminist position needs to be both updated and revised in order to account for the different, sometimes contradictory mechanisms for the capitalization of nature that have become prominent today. I will underscore two developments in particular: the dominance of neoliberalism and the development of biotechnology. I will conclude by summing up the theoretical grounds on which a contemporary political alliance between feminist and ecological struggles against capitalism can be built.     

Self‐Compassion as a Facet of Neuroticism? A Reply to the Comments of Neff,Tóth‐Király,and Colosimo (2018)

In this paper, we respond to comments by Neff et al. (2018) made about our finding that the negative dimensions of self‐compassion were redundant with facets of neuroticism (rs ≥ 0.85; Pfattheicher et al., 2017) and not incrementally valid. We first provide epistemological guidance for establishing psychological constructs, namely, three hurdles that new constructs must pass: theoretically and empirically sound measurement, discriminant validity, and incremental validity—and then apply these guidelines to the self‐compassion scale. We then outline that the critique of Neff et al. (2018) is contestable. We question their decisions concerning data‐analytic methods that help them to circumvent instead of passing the outlined hurdles. In a reanalysis of the data provided by Neff et al. (2018), we point to several conceptual and psychometric problems and conclude that self‐compassion does not overcome the outlined hurdles. Instead, we show that our initial critique of the self‐compassion scale holds and that its dimensions are best considered facets of neuroticism. © 2018 European Association of Personality Psychology
