Subclaims¶

q2 i? Functional connectivity of the hippocampus-VLPFC-LOC network decreased during retrieval with visual distractors and no longer distinguished correct from incorrect retrieval. → Wais 2014 q2 i? Reduced left IFG connectivity with left LOC was correlated with reduced connectivity with left hippocampus across participants. → Wais 2014 (2)

Evidence¶

Wais 2014¶

Wais, P. E., and Gazzaley, A. (2014). Distractibility during retrieval of long-term memory: domain-general interference, neural networks and increased susceptibility in normal aging. Frontiers in Psychology. https://doi.org/10.3389/fpsyg.2014.00280

q2 · i? · review · r2

fMRI experiment using the same paradigm, with beta-series correlation analyses seeded by left hippocampus and left LOC ROIs. "functional connectivity decreased in association with VD correct, relative to SHUT correct"; no effect size printed.

"In comparisons of the left-lateralized hippocampus-VLPFC-LOC network between the SHUT and VD conditions, functional connectivity decreased in association with VD correct, relative to SHUT correct, and, critically, no longer supported episodic retrieval (i.e., functional connectivity was not different between VD correct and VD incorrect)."

q2 · i? · review · r2

Regression analysis of connectivity change between conditions across participants, shown in Figure 3B. "the change in network connectivity between SHUT correct and VD correct was correlated"; no correlation coefficient printed.

"a regression analysis revealed that the change in network connectivity between SHUT correct and VD correct was correlated for an index of left VLPFC with left hippocampus connectivity and an index of left VLPFC with left LOC connectivity (Figure 3B)."

Discussion¶

Learner Variables¶

• Attention — predictor: learners who differ on it differ in outcomes

Related Claims¶

• Older adults show greater distractibility than younger adults during episodic retrieval of long-term memory details — related
• Auditory distraction disrupts episodic retrieval equivalently to visual distraction, indicating a domain-general interference effect in long-term memory — related
• Perturbing left VLPFC with rTMS exacerbates the disruptive effect of visual distraction on episodic retrieval, indicating a causal role in resolving interference — related
• Irrelevant visual stimuli present during a memory test diminish the fidelity of episodic details retrieved from long-term memory in younger adults — a broader claim this one bears on
