Phrase frequency effects in free recall: Evidence for redintegration

Publication date: December 2017 Source:Journal of Memory and Language, Volume 97 Author(s): Cassandra L. Jacobs, Gary S. Dell, Colin Bannard Three experiments examined the effects of word and phrase frequency on free recall. Word frequency did not affect word recall, but when participants studied and recalled lists of compositional adjective-noun phrases (e.g. alcoholic beverages), phrase frequency had a consistently beneficial effect: both words from frequent phrases were more likely to be recalled than for infrequent phrases, providing evidence that long-term memory for phrases can aid in pattern completion, or redintegration. We explain these results and those of a previous study of phrase frequency effects in recognition memory (Jacobs, Dell, Benjamin, & Bannard , 2016) by assuming that the language processing system provides features that are linked to episodic contexts. Recall tasks map from these contexts to linguistic elements, and recognition maps from linguistic elements to contexts. Word and phrase frequency effects in both memory tasks emerge both within the language processing system and from multiple stored episodes, and the fact that the representations of phrases are tied to knowledge of their component words, rather than being representational islands.

Memory encoding and recall involving complex, effortful cognitive processes are impaired by alcohol primarily due to impairment of a select few, but crucial, cortical areas. This review shows how alcohol affects some, but not all, aspects of eyewitnesses' oral free recall performance. The principal results, so far, are that: a) free recall reports by intoxicated witnesses (at the investigated BAC‐levels) may contain less, but as accurate, information as reports by sober witnesses; b) immediate reports given by intoxicated witnesses may yield more information compared to reports by sober witnesses given after a one week d...

Authors: Bassetti CL, Bargiotas P Abstract Rapid eye movement sleep behavior disorder (RBD) is a brain disorder, characterized by the dream enactment during rapid eye movement (REM) sleep due to a lack of physiologic muscle atonia and increased muscle twitching. Schenk was the first to describe this disorder in 1986; however, few authors reported in the 1970-1980s loss of physiological muscle atonia combined with dream enactment in the course of brainstem disorders and as a consequence of alcoholism and antidepressant treatment. RBD affects less than 1% of the adult population, but can be found in up to 25-50% of n...

Conclusion: Proactive and targeted intervention strategies against psychoactive substance use among people living with HIV/AIDS using what is known about vulnerability are implied. Further research on the complex relationship between HIV/AIDS and psychoactive substance use is indicated. PMID: 29148637 [PubMed - in process]

Conclusion UPLC-ELSD is a simple, reliable and effective method for analysis of the sweet chemicals in wolfberries. Wolfberry fruits at the different ripening stages were significant different in sweetness. L. truncatum and L. dasystemum could be the potential sources of wolfberry fruit sources.

This study aimed to explore the effects of polysaccharides of Citrus grandis L. Osbeck (PCG) in relieving chronic pharyngitis and illustrate the underlying mechanisms. Polysaccharides were obtained from PCG by column chromatographic extraction. Six clinical symptom scores, such as the severity of itchy throat, hoarseness, pain, odynophagia, cough and otalgia were evaluated in chronic pharyngitis patients after the oral intake of PCG. The effects of polysaccharides on chronic pharyngitis were investigated in ammonia-stimulated rabbits through pathology analysis. The levels of inflammatory markers in the peripheral blood T c...
