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...

Conclusions: The hierarchical structure of the CART model provides a diagnostic algorithm linked with the risk of malignancy at every step of the procedure. It also provides guidance on the use of ancillary examinations as it goes by simple, human understandable rules.Acta Cytologica

WASHINGTON (Reuters) - U.S. President Donald Trump passed a cognitive test and is in overall excellent health, but needs to lose 10 to 15 pounds (4.5 to 6.8 kg) by eating better and starting to exercise, the White House physician said on Tuesday.
CONCLUSION: Our findings do not support epicardial fat's beneficial effects on bone health, whereas general adiposity has an osteotropic effect. The association between EFT and BMC is through common genetic component factors. PMID: 29332861 [PubMed - as supplied by publisher]
CONCLUSIONS: Affected infants and toddlers in Fukushima suggested some growth disturbances and early adiposity rebound, which can cause obesity. The future growth of children affected by disasters should be followed carefully. PMID: 29332860 [PubMed - as supplied by publisher]
Los Angeles-based model Lauren Wasser, 29, lost her right leg in 2012 and had the other one amputated last week. 'Life is about to be so different, again!' she said in a post before the surgery.
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.
