The Familiarity Bias
0 Views •
2026
Familiarity bias is a psychological tendency in which investors prefer well-known assets and avoid unfamiliar investments, often to the detriment of their portfolios. This bias arises from an aversion to uncertainty and a fear of negative outcomes associated with lesser-known financial instruments. While investors may believe they are making safer choices, their reluctance to explore a broader range of assets can lead to suboptimal diversification and increased risk exposure.Familiarity bias...

Electrophysiological research is an important tool for identifying biomarkers of developmental disorders, including Autism Spectrum Disorders (ASD), but data collection in these populations remains challenging. This work presents a familiarization protocol to accompany research that includes electroencephalography (EEG) to improve the likelihood of collecting EEG data from children with ASD.

Learning and Memory: The Remember-Know Task
0 Views •
2023
Source: Laboratories of Jonas T. Kaplan and Sarah I. Gimbel—University of Southern California Our experience of memory is varied and complex. Sometimes we remember events in vivid detail, while other times we may only have a vague sense of familiarity. Memory researchers have made a distinction between memories that are recollected versus those that are familiar. A recollected item is one that is not only remembered, but carries with it details of the time at which it was learned or encoded.

We report an efficient and simple method to isolate embryos at early stages of development from Arabidopsis thaliana seeds. Up to 40 embryos can be isolated in 1 hr to 4 hr, depending on the downstream application. The procedure is suitable for transcriptome, DNA methylation, reporter gene expression, immunostaining and fluorescence in situ hybridization analyses.
FAQs
Researchers examine whether a recognition decision includes recoverable details about the earlier event. A response supported by information such as the learning episode reflects recollection, whereas a response based only on a general sense of prior encounter reflects familiarity. This distinction allows identical accuracy scores to be analyzed according to the memory process that produced them.
Remember-know judgments separate recognition accompanied by conscious retrieval of event details from recognition based on a feeling of prior occurrence without contextual recovery. Participants report whether they remember something specific about the encounter or merely know that the item appeared before. Psychologists use these responses to estimate the relative contributions of the two processes.
Correctly identifying a previously studied item does not, by itself, show how that decision was reached. One person may retrieve details from the original episode, while another may rely on a stronger prior-exposure signal without recovering context. Recollection familiarity research therefore looks beyond overall accuracy to characterize the quality and basis of recognition.
A typical study presents participants with faces, words, objects, or other items during learning, followed by a recognition test. Items from the earlier phase are mixed with items not previously encountered, and participants judge whether each item is old or new. Researchers may then collect remember-know judgments to examine the process supporting each decision.
Psychologists alter conditions during learning or testing and observe whether recognition performance changes in its recollective or familiarity-based component. Such manipulations can reveal whether a condition primarily affects access to event-specific information, a general memory signal, or both. Comparing resulting recognition and remember-know patterns helps link experimental conditions to underlying memory operations.
The distinction provides a framework for studying recognition across learning, aging, amnesia, and eyewitness identification. In each area, researchers can ask whether performance depends on recovered episodic details or on a less specific sense of prior exposure. This analysis helps interpret why people may recognize an item while differing in the contextual information they can report.
