Immediate Memory

Emotional arousal induced after learning has been shown to modulate memory consolidation. However, it is unclear whether the effect of postlearning arousal can extend to different aspects of memory. This study examined the effect of postlearning positive arousal on both item memory and source memory. Participants learned a list of neutral words and took an immediate memory test. Then they watched a positive or a neutral videoclip and took delayed memory tests after either 25 minutes or 1 week had elapsed after the learning phase. In both delay conditions, positive arousal enhanced consolidation of item memory as measured by overall recognition. Furthermore, positive arousal enhanced consolidation of familiarity but not recollection. However, positive arousal appeared to have no effect on consolidation of source memory. These findings have implications for building theoretical models of the effect of emotional arousal on consolidation of episodic memory and for applying postlearning emotional arousal as a technique of memory intervention.

Negative Antwortverzerrungen

Negative Antwortverzerrungen werden quantitativ mit expliziten Beschwerdenvalidierungstests oder mit eingebetteten Parametern untersucht. Es wird die Kriteriumsvalidität der Standardabweichung von Reaktionszeiten als eingebetteter Parameter zur Untersuchung negativer Antwortverzerrungen überprüft. In die Studie wurden 26 Frauen und 65 Männer mit Schädelhirnverletzungen einbezogen. Abhängige Variable war die Standardabweichung der Reaktionszeiten (Untertest Alertness, Testbatterie zur Aufmerksamkeitsprüfung). Prädiktorvariablen in der multivariaten Kovarianzanalyse waren das Alter der Probanden und folgende Testrohwerte: Trail Making Test (Formen A und B), Parameter GSI der Symptomcheckliste, Untertest Zahlennachsprechen vorwärts aus der Wechsler Memory Scale, Strukturierter Fragebogen Simulierter Symptome, der mittlere Wert der in Prozentzahlen ausgedrückten richtigen Antworten der Parameter IR, DR und CNS des Word Memory Tests (WMT), das Geschlecht der Probanden sowie die dichotomisierte Gruppierung von Patienten mit oder ohne klinisch fassbaren Auffälligkeiten der Aufmerksamkeit. Von den Prädiktorvariablen stellte sich allein der mittlere Wert der in Prozent ausgedrückten richtigen Antworten des WMT als signifikant heraus. Probanden mit einer geringen Anzahl richtiger Antworten im WMT zeigten größere Standardabweichungen. Alle weiteren einbezogenen Prädiktoren – insbesondere beide Aufmerksamkeitsparameter – hatten in Bezug auf die Standardabweichungen keinen signifikanten Einfluss.

Explicit Feedback

Abstract. To date there has been relatively little research within the domain of metamemory that examines how individuals monitor their performance during memory tests, and whether the outcome of such monitoring informs subsequent memory predictions for novel items. In the current study, we sought to determine whether spontaneous monitoring of test performance can in fact help individuals better appreciate their memory abilities, and in turn shape future judgments of learning (JOLs). Specifically, in two experiments we examined recognition memory for visual images across three study-test cycles, each of which contained novel images. We found that across cycles, participants’ JOLs did in fact increase, reflecting metacognitive sensitivity to near-perfect levels of recognition memory performance. This finding suggests that individuals can and do monitor their test performance in the absence of explicit feedback, and further underscores the important role that test experience can play in shaping metacognitive evaluations of learning and remembering.

Commonly used rating scales and tests have been found lacking reliability and validity, for example in neurodegenerative diseases studies, owing to not making recourse to the inherent ordinality of human responses, nor acknowledging the separability of person ability and item difficulty parameters according to the well-known Rasch model. Here, we adopt an information theory approach, particularly extending deployment of the classic Brillouin entropy expression when explaining the difficulty of recalling non-verbal sequences in memory tests (i.e., Corsi Block Test and Digit Span Test): a more ordered task, of less entropy, will generally be easier to perform. Construct specification equations (CSEs) as a part of a methodological development, with entropy-based variables dominating, are found experimentally to explain (r=R2 = 0.98) and predict the construct of task difficulty for short-term memory tests using data from the NeuroMET (n = 88) and Gothenburg MCI (n = 257) studies. We propose entropy-based equivalence criteria, whereby different tasks (in the form of items) from different tests can be combined, enabling new memory tests to be formed by choosing a bespoke selection of items, leading to more efficient testing, improved reliability (reduced uncertainties) and validity. This provides opportunities for more practical and accurate measurement in clinical practice, research and trials.
