Most models of how perceivers infer the widespread attitudes and qualities of social groups revolve around either the self (social projection, false consensus) or stereotypes (stereotyping). The author suggests people rely on both of these inferential strategies, with perceived general similarity moderating their use, leading to increased levels of projection and decreased levels of stereotyping. Three studies featuring existing individual differences in perceived similarity as well as manipulated perceptions supported the predictions, with similarity yielding increased projection to, and decreased stereotyping of, various in-groups and out-groups. Evidence that projection and stereotyping may serve as inferential alternatives also emerged. The model and accompanying results have implications for research on social comparison and projection, stereotyping and prejudice, and social inference.

Bayesian Phylogenetic Lineage Reconstruction with Loss of Heterozygosity Mutations Derived from Single-Cell RNA Sequencing.

Mutations are acquired frequently, such t`hat each cell's genome inscribes its history of cell divisions. Loss of heterozygosity (LOH) accumulates throughout the genome, offering large encoding capacity for phylogenetic inference of cell lineage.In this chapter, we demonstrate a method, using single-cell RNA sequencing, for reconstructing cell lineages from inferred LOH events in a Bayesian manner, annotating the lineage with cell phenotypes, and marking developmental time points based on X-chromosome inactivation.

Zebra finches undergo a gradual refinement of their vocalizations, transitioning from variable juvenile songs to the stereotyped song of adulthood. To investigate the neural mechanisms underlying song crystallization-a critical phase in this developmental process-we performed intracellular recordings in HVC (a premotor nucleus essential for song learning and production) of juvenile birds. We then compared these recordings to previously published electrophysiological data from adult birds.

The assembly and maintenance of neural circuits is crucial for proper brain function. Although the assembly of brain circuits has been extensively studied, much less is understood about the mechanisms controlling their maintenance as animals mature. In the olfactory system, the axons of olfactory sensory neurons (OSNs) expressing the same odor receptor converge into discrete synaptic structures of the olfactory bulb (OB) called glomeruli, forming a stereotypic odor map.

The hippocampus is the most studied brain region, but little is known about signal throughput-the simplest, yet most essential of circuit operations-across its multiple stages from perforant path input to CA1 output. Using hippocampal slices derived from male mice, we have found that single-pulse lateral perforant path (LPP) stimulation produces a two-part CA1 response generated by LPP projections to CA3 ("direct path") and the dentate gyrus ("indirect path"). The latter, indirect path was far more potent in driving CA1 but did so only after a lengthy delay.

Prior work on PIF in medical students has focused on the development of a physician identity. However, little is known about how medical students might begin to develop divergent specialty-specific identities during medical school.
