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.

Authors: McDonald K Abstract LGBTQ adolescents experience higher rates of mental health disorders than their heterosexual peers. The purpose of this systematic review of the literature was to examine studies evaluating social support and its effects on mental health in the LGBTQ adolescent population. Higher levels of social support were associated with positive self-esteem. Lack of social support (or low social support) was associated with higher levels of depression, anxiety, alcohol or drug misuse, risky sexual behaviors, shame, and low self-esteem. Interdisciplinary research teams from multiple and diverse prof...

AbstractSurface gold –polymer nanocomposites are prepared by using the thermal convection method for the deposition of gold colloids onto the surface of four polymer films: poly(-vinyl alcohol) (PVA), SU-82, poly(styrene) (PS), and poly(dimethyl siloxane) (PDMS). In order to increase the plasmonic sensitivity of the p latforms, the nanocomposites are, subsequently, subjected to an incremental heating in the range of 80–200 °C. As a consequence, small aggregates are formed and uniformly dispersed on the surface of the film. In addition, because of the softening of the polymer, a small fraction of nanopa...

Conclusion: This is a small study likely to be skewed by sampling bias but is thought to be the first multidisciplinary survey of the management of chronic pancreatitis in the United Kingdom and Ireland. The results show a need for comprehensive access to specialist pancreatitis MDT care and there remains substantial variation in management.Dig Surg

Conclusion: Compared to non-smokers, promoter-related deoxyribonucleic acid methylation of the ANP promoter was significantly elevated on days 7 and 14 of withdrawal in tobacco-dependent patients. Baseline methylation status of the ANP promoter was not significantly different from controls, arguing for an impaired regulation during withdrawal. Eur Addict Res 2017;23:306 –311
