Can signal detection theory explain everyday amnesia (high confident misses)?

Publication Type:Academic Journal

Source(s):Neuropsychologia [Neuropsychologia] 2022 Feb 10; Vol. 166, pp. 108115. Date of Electronic Publication: 2021 Dec 09.

Abstract:Levi et al. (2021) critique the concept of everyday amnesia (high confident misses) by arguing that these are simply due to criterion shifts within a signal detection framework. We agree that signal detection figures can be drawn to conceptualize the r...

A Signal Detection Analysis of Olfactory Learning in 12-Month-Old 5xFAD Mice.

Publication Type:Academic Journal

Source(s):Journal of Alzheimer's disease : JAD [J Alzheimers Dis] 2022; Vol. 88 (1), pp. 37-44.

Abstract:Although Alzheimer's disease is most often studied in terms of memory impairments, olfactory dysfunction begins in the early stages. We tested olfactory learning, sensitivity, and response bias using signal detection methods in 12-month-old male and fe...

A Novel Improved Threshold Adaptive Forgetting Variable Step Size Blind Separation Model for Weak Signal Detection.

Publication Type:Academic Journal

Source(s):Shock & Vibration. 9/12/2022, p1-15. 15p.

Abstract:The online blind source separation (BSS) is seriously disturbed by strong noise when extracting weak signals and has the defects that it cannot both give consideration to convergence speed and steady-state error. In order to solve the abovementioned pr...

Testing the foundations of signal detection theory in recognition memory.

Publication Type:Academic Journal

Source(s):Psychological review [Psychol Rev] 2021 Nov; Vol. 128 (6), pp. 1022-1050. Date of Electronic Publication: 2021 Jun 10.

Abstract:Signal detection theory (SDT) plays a central role in the characterization of human judgments in a wide range of domains, most prominently in recognition memory. But despite its success, many of its fundamental properties are often misunderstood, espec...

Information-theoretic signal detection theory.

Publication Type:Academic Journal

Source(s):Psychological review [Psychol Rev] 2021 Oct; Vol. 128 (5), pp. 976-987. Date of Electronic Publication: 2021 Jul 19.

Abstract:Signal detection theory (SDT), the standard mathematical framework by which we understand how stimuli are classified into distributions such as signal or noise, is an essential part of the modern psychologist's toolkit. This article introduces some mat...

An Approach for Cardiac Coronary Detection of Heart Signal Based on Harris Hawks Optimization and Multichannel Deep Convolutional Learning.

Publication Type:Academic Journal

Source(s):Computational Intelligence & Neuroscience. 7/30/2022, p1-17. 17p.

Abstract:Automatic diagnosis of arrhythmia by electrocardiogram has a significant role to play in preventing and detecting cardiovascular disease at an early stage. In this study, a deep neural network model based on Harris hawks optimization is presented to ar...

Design and evaluation of a dual-beam read/write configuration for optical storage.

Publication Type:Academic Journal

Source(s):Journal of Applied Physics. 7/21/2022, Vol. 132 Issue 3, p1-12. 12p.

Abstract:Increasing the number of read/write layers and ensuring the quality of read/write signals are the key factors to enhance the optical storage capacity. However, limited by the single optical path, the structure, and the material of the disk, the existin...

When are randomized trials unnecessary? A signal detection theory approach to approving new treatments based on non-randomized studies.

Publication Type:Academic Journal

Source(s):Journal of evaluation in clinical practice [J Eval Clin Pract] 2021 Aug; Vol. 27 (4), pp. 735-742. Date of Electronic Publication: 2020 Oct 26.

Abstract:Rationale, Aims and Objectives: New therapies are increasingly approved by regulatory agencies such as the Food and Drug Administration (FDA) and the European Medicines Agency (EMA) based on testing in non-randomized clinical trials. These treatments h...

Individual differences in the perception of cue-outcome contingencies: A signal detection analysis.

Publication Type:Academic Journal

Source(s):Behavioural processes [Behav Processes] 2021 Jul; Vol. 188, pp. 104398. Date of Electronic Publication: 2021 Apr 24.

Abstract:In a signal detection theory (SDT) approach to associative learning, one assumes that, when a subject is exposed to a flow of stimuli, an association is created between the internal representations of a cue and of an outcome, allowing the representatio...

Evaluating a typology of signals for automatic detection of complementarity.

Publication Type:Academic Journal

Source(s):Domínios de Lingu@gem. oct-dec2022, Vol. 16 Issue 4, p1517-1543. 27p.

Abstract:Em uma coleção de notícias sobre um mesmo evento, duas sentenças de textos distintos podem expressar diferentes fenômenos multidocumento (redundância, complementaridade e contradição). A Cross-Document Structure Theory (CST) provê rótulos para represen...
