The list strength effect in cued recall

Publication date: August 2017 Source:Journal of Memory and Language, Volume 95 Author(s): Jack H. Wilson, Amy H. Criss Episodic memory is the process by which information about experienced events is encoded and retrieved. Successful retrieval of episodic memories is dependent on the way in which memory is tested and as a result many effects and theories of episodic memory are task dependent. One such finding is the list strength effect. In free recall, a positive list strength effect is observed; memory for a given item is harmed by the presence of other strongly encoded items and helped by the presence of other weakly encoded items. In recognition, a null list strength is observed; memory for a given item is unaffected by the strength of other items. Such differential empirical findings are crucial to understanding memory, but it is undesirable to have multiple task-specific theories rather than a unified theory of memory. Here we use cued recall, a task that shares properties of both free recall and recognition, to move toward that goal. In a series of 5 experiments, we observed a null list strength effect in cued recall. We suggest that a successful theory would entail the use of both item and context information during retrieval, consistent with the approach of the Search of Associative Memory model.

PPAR-γ Agonists and Their Role in Primary Cicatricial Alopecia. PPAR Res. 2017;2017:2501248 Authors: Harnchoowong S, Suchonwanit P Abstract Peroxisome proliferator-activated receptor γ (PPAR-γ) is a ligand-activated nuclear receptor that regulates the transcription of various genes. PPAR-γ plays roles in lipid homeostasis, sebocyte maturation, and peroxisome biogenesis and has shown anti-inflammatory effects. PPAR-γ is highly expressed in human sebaceous glands. Disruption of PPAR-γ is believed to be one of the mechanisms of primary cicatricial alopecia (PCA) pathoge...

In this study, eleven volunteers (aged 37-52) took six early-afternoon naps (30 minutes) in their occupational workplace, under two different conditions: control 'Naps' or 'Naps + RT' with a within-subjects design. Our results demonstrate that adding RT to naps changes sleep architecture, with a significant increase in the TST, mostly due to N2 sleep stage (and N3, to a lesser extent). Therefore, the deepening of short naps with RT involving hypnosis might be a successful non-pharmacological way to extend sleep duration and to deepen sleep in occupational settings.
