Source memory research aims at understanding how people remember the origin of information (e.g., Where did I read the latest news?). This double symposium brings together findings from both basic (Part 1) and more applied (Part 2) source memory research. The first session highlights new developments in modeling approaches as well as empirical work addressing fundamental determinants of source memory.
Beatrice G. Kuhlmann opens the session with “A Storage-Retrieval Extension of the Two-High-Threshold Multinomial Model of Source Monitoring.”, introducing an extended version of the often-used two-high-threshold multinomial model of source monitoring (2HTSM, Bayen et al., 1996). This extended version distinguishes between storage and retrieval components of source memory by incorporating two separate source-memory parameters.
Meike Kroneisen follows with “The Rare and the Common: Can Rarity Influence the Animacy Effect in Source Memory?”, investigating whether the animacy advantage in source memory depends on the relative frequency of animate and inanimate stimuli. Her talk provides insights into how base-rate expectations and attention shape encoding and retrieval.
In “Source Memory and Metamemory for Concrete and Abstract Words,” Désirée Schönung examines how people monitor their memory for different word types. The talk focuses on whether individuals distinguish between item and source memory in their metamemory judgments by recognizing that concreteness affects item but not source memory.
Further advancing model-related aspects, Hilal Tanyas presents in her talk “Modeling Latency Processes in Source Monitoring” a formal modeling approach that integrates response times to the 2HTSM. This allows estimating the relative speed of memory- and guessing-based processes.
Finally, Lena Nadarevic bridges to more applied questions of source memory in her talk “Source Effects in Memory for Truth and Falsity: A Comparison of Self-Generated Judgments and External Feedback”. Across two experiments, she investigates whether participants remember self-generated subjective truth judgments better than externally provided objective feedback, consistent with the generation effect.
Together, these talks illustrate the range of current approaches to studying source memory, advancing theoretical and methodological understanding of source memory processes. The first session concludes with a general discussion, leading over to Part II: Source Memory - Applied Research.

Source attributions, such as judging who told you something, involve item memory, source memory, and guessing processes. The two-high-threshold multinomial model of source monitoring (2HTSM; Bayen, Murnane, & Erdfelder, 1996) enables the separate measurement of these processes. However, its memory parameters do not separate storage and retrieval. In turn, lower source memory probabilities (2HTSM parameter d) may stem from failed source storage and/or failed source retrieval. Applying our novel test paradigm, where the standard source monitoring test is complemented by a source recognition test with reinstatement of source features from the study phase (Symeonidou & Kuhlmann, 2021), we propose a tailored extension of the 2HTSM to separately measure the probabilities of source storage (new parameter ds) and source retrieval (new parameter dr). In an experiment with N = 108 younger adults using words as items presented by two female speakers (source features: name + picture + voice) as sources, we show that this model fits empirical data well. Further crucial, targeted manipulations of storage (repetition at study) and retrieval (partial reinstatement of the speaker’s name + picture but not voice in the first test) selectively influenced the source storage and retrieval parameter, respectively, validating their psychological interpretation. In addition, we will present an overview of applications of this model to the study of source forgetting and age-related deficits in source memory.
