Data compression in memory is a cognitive process allowing participants to cope with complexity to reduce information load. However, previous studies have not yet considered the hypothesis that this process could also lead to over-simplifying information due to haphazard amplification of the compression process itself. For instance, we could expect that the over-regularized features of a visual scene could produce false recognition of patterns, not because of storage capacity limits but because of an errant compression process. To prompt memory compression in our participants, we used multielement visual displays for which the underlying information varied in compressibility. The compressibility of our material could vary depending on the number of common features between the multi-dimensional objects in the displays. We measured both accuracy and response times by probing memory representations with probes that we hypothesized could modify the participants' representations. We confirm that more compressible information facilitates performance, but a more novel finding is that compression can produce both typical memory errors and lengthened response times. Our findings provide clearer evidence of the forms of compression that participants carry out.Several space-based and object-based attention studies suggest these selection mechanisms may be voluntarily deployed, depending on task parameters and the attentional scope of the observer. Here, we sought to elucidate factors related to involuntary deployment of object-mediated space-based attention through two experiments. Experiment 1 used a modified flanker task where a target and nearby distractor were presented within the same or different object frames, such that an object-based attentional spread should be detrimental to performance. Results showed the presence of a flanker effect with no significant difference in magnitude between grouping conditions, indicating participants may have uniformly used a diffused attentional spotlight regardless of object segmentation. In a second experiment, we manipulated the extent of the observer's sustained attentional scope via an inducer task to determine whether object-based selection depends on the initial spotlight size. The results revealed object-based effects solely when attention narrowly encompassed the target, but not when it was widened to include the distracting flanker. This suggests the deployment of object-based attention may occur when spatial attention is initially focused narrowly. Because selecting the whole object frame directly interfered with task goals, we conclude that object-based attention may not always fully conform to relevant task goals or operate in a goal-oriented manner. We discuss these results in the context of existing literature while proposing a reconciliation of previously inconsistent findings of object-based selection.Wireless and precise stimulation of deep brain structures could have important applications to study intact brain circuits and treat neurological disorders. Herein, we report that magnetoelectric nanoparticles (MENs) can be guided to a targeted brain region to stimulate brain activity with a magnetic field. We demonstrated the nanoparticles' capability to reliably evoke fast neuronal responses in cortical slices ex vivo. After fluorescently labeled MENs were intravenously injected and delivered to a targeted brain region by applying a magnetic field gradient, a magnetic field of low intensity (350-450 Oe) applied to the mouse head reliably evoked cortical activities, as revealed by two-photon and mesoscopic imaging of calcium signals and by an increased number of c-Fos expressing cells after stimulation. Neither brain delivery of MENs nor the magnetic stimulation caused significant increases in astrocytes and microglia. Thus, MENs could enable a non-invasive and contactless deep brain stimulation without the need of genetic manipulation.Recent advances in plant genomics revealed numerous factors related to drought tolerance, including a family of WRKY transcription factors. The aim of this study was to evaluate polymorphism of the TaWRKY2-D1 across a range of bread wheat cultivars, interspecific hybrids, and wild wheat relatives within the Triticum genus as a potential molecular target for marker-assistant selection. The initial sequencing of the TaWRKY2-D1 gene in six Ukrainian commercial cultivars detected some sequence variations along the ~ 1.8 kb of gene promoter and the followed coding region composed of four exons and three introns. Based on the gained sequence information, five sets of primers covering different gene regions were designed to annotate theTaWRKY2-D1 genetic diversity in 202 wheat cultivars, including 77 accessions from the CIMMYT collection, 72 commercial varieties cultivated in Ukraine, and 53 hybrids and wild wheat species. The combination of developed DNA markers enabled effective and reproducible annotation of cultivars genetic diversity. The primers set targeting introns adjusted to the gene's exon 3, turned out to be the most informative for screening heterogeneity of the TaWRKY2-D1. The developed molecular markers represent effective, informative means for selecting drought tolerance germplasm donors to promote wheat breeding programs.Adolescents with internalizing problems are more prone to feelings of guilt and shame, experience more guilt-induction, and report more negative parenting, but little is known about the way these processes are associated nor the extent to which they occur within real-time parent-adolescent interactions. UMI77 The current study sought to clarify these links by investigating whether negatively biased perceptions of maternal communication mediate links between adolescent internalizing symptoms and their feelings of guilt, shame, and guilt-induction during real-time mother-adolescent discussions. One hundred twenty-three mother-adolescent dyads participated in the study. These dyads were moderately diverse in both race/ethnicity (53% White, 29% Black, 12% Hispanic) and family income (26% earned less than $30,000/year, 22% earned more than $100,000/year) and included adolescents who ranged in age from 12 to 17 (Mage = 13.99) and were approximately half female (54%). Mothers and adolescents engaged in lab discussions about issues of conflict and guilt and rated mothers' positive and negative communication during the tasks; observers rated these same behaviors.
