Digit Recall

Although information is frequently paired with music to enhance recall, there is a lack of basic research investigating how aspects of recorded music, as well as how it is presented, facilitate working memory. Therefore, the purpose of this study was to determine the effects of visual and aural presentation styles, rhythm, and participant major on working memory as measured by sequential monosyllabic digit recall performance. We isolated visual and aural presentation styles and rhythm conditions during six different treatment stimuli presented on a computer screen in the study: (a) Visual Rhythm; (b) Visual No Rhythm; (c) Aural Rhythm; (d) Aural No Rhythm; (e) Visual + Aural Rhythm; (f) Visual + Aural No Rhythm. Participants’ ( N = 60; 30 nonmusic majors and 30 music majors) task was to immediately recall the information paired with music within each condition. Analyses of variance indicated a significant difference between the visual and visual + aural presentation style conditions with the visual + aural condition having more accurate recall. While descriptive data indicated that rhythm tended to facilitate recall, there was no significant difference between rhythm and no rhythm conditions. Nonmusic major participants tended to have slightly more accurate recall than music major participants, although this difference was not significant. Participants tended to have higher recall accuracy during primacy and recency serial positions. As participants had most accurate recall during the visual + aural presentation style conditions, it seems that the multi-sensory presentation modes can be effective for teaching information to be immediately recalled as long as they do not contain too much information and overload the limited storage capacity of working memory. Implications for clinical practice, limitations, and suggestions for future research are provided.

Musical Elements

Information is often paired with music to facilitate memory and learning. However, there is a lack of basic research investigating how visual and auditory presentation styles and musical elements might facilitate recall. The purpose of this study is to isolate and determine the effects of visual and auditory presentation styles and musical elements on working memory as measured by sequential monosyllabic digit recall performance. Recall was tested on 60 undergraduate university students during six different conditions: (a) Visual + Auditory Chant, (b) Visual + Auditory Melody, (c) Visual + Auditory Speech, (d) Auditory Chant, (e) Auditory Melody, and (f) Auditory Speech. There was a significant interaction between presentation style and musical element conditions. There were significant differences between auditory and visual + auditory conditions in the melody and speech conditions but not in the chant condition. In all cases, the auditory condition had more accurate recall than the visual + auditory condition, with recall differences largest during the speech condition. There was no significant difference between chant and melody but significant differences between chant and speech and melody and speech in the visual + auditory condition. In the auditory condition, recall accuracy was lower for speech than for melody or chant. There was no significant difference between chant and melody, chant and speech, or melody and speech in the visual + auditory condition. Congruent with existing research, the addition of visual input likely overloaded working memory resulting in worse recall. Implications for clinical practice, limitations, and suggestions for future research are provided.

Capacity limitations in working memory (WM) necessitate the need to effectively control its contents. Here, we examined the effect of cabergoline, a dopamine D2 receptor agonist, on WM using a continuous report paradigm that allowed us to assess the fidelity with which items are stored. We assessed recall performance under three different gating conditions: remembering only one item, being cued to remember one target among distractors, and having to remember all items. Cabergoline had differential effects on recall performance according to whether distractors had to be ignored and whether mnemonic resources could be deployed exclusively to the target. Compared with placebo, cabergoline improved mnemonic performance when there were no distractors but significantly reduced performance when distractors were presented in a precue condition. No significant difference in performance was observed under cabergoline when all items had to be remembered. By applying a stochastic model of response selection, we established that the causes of drug-induced changes in performance were due to changes in the precision with which items were stored in WM. However, there was no change in the extent to which distractors were mistaken for targets. Thus, D2 agonism causes changes in the fidelity of mnemonic representations without altering interference between memoranda.

The Impact

Deaf and hard of hearing (DHH) children have been claimed to lag behind their hearing peers in various domains of cognitive development, especially in implicit learning, executive function, and working memory. Two major accounts of these deficits have been proposed: one based on a lack of auditory access, and one based on a lack of language access. This chapter reviews these theories in relation to the available evidence and concludes that there is little evidence of direct effects of diminished auditory access on cognitive development that could not also be explained by diminished language access. Specifically, reports of deficits in implicit learning are not broadly replicable. Some differences in executive function do stem from deafness itself but are not necessarily deficits. Where clinically relevant deficits in executive function are observed, they are inconsistent with the predictions of accounts based on auditory access, but consistent with accounts based on language access. Deaf–hearing differences on verbal working memory tasks may indicate problems with perception and/or language, rather than with working memory. Deaf–hearing differences on nonverbal tasks are more consistent with accounts based on language access, but much more study is needed in this area. The chapter concludes by considering the implications of these findings for psychological theory and for clinical/educational practice and by identifying high-priority targets for future research.

Ovary Syndrome

Abstract Context Polycystic ovary syndrome (PCOS) is a common endocrine condition affecting 8% to 13% of women across the lifespan. PCOS affects reproductive, metabolic, and mental health, generating a considerable health burden. Advances in treatment of women with PCOS has been hampered by evolving diagnostic criteria and poor recognition by clinicians. This has resulted in limited clinical and basic research. In this study, we provide insights into the current and future research on the metabolic features of PCOS, specifically as they relate to PCOS-specific insulin resistance (IR), that may affect the most metabolically active tissue, skeletal muscle. Current Knowledge PCOS is a highly heritable condition, yet it is phenotypically heterogeneous in both reproductive and metabolic features. Human studies thus far have not identified molecular mechanisms of PCOS-specific IR in skeletal muscle. However, recent research has provided new insights that implicate energy-sensing pathways regulated via epigenomic and resultant transcriptomic changes. Animal models, while in existence, have been underused in exploring molecular mechanisms of IR in PCOS and specifically in skeletal muscle. Future Directions Based on the latest evidence synthesis and technologies, researchers exploring molecular mechanisms of IR in PCOS, specifically in muscle, will likely need to generate new hypothesis to be tested in human and animal studies. Conclusion Investigations to elucidate the molecular mechanisms driving IR in PCOS are in their early stages, yet remarkable advances have been made in skeletal muscle. Overall, investigations have thus far created more questions than answers, which provide new opportunities to study complex endocrine conditions.

Working Memory Updating

AbstractAs the world’s population is aging rapidly, cognitive training is an extensively used approach to attempt improvement of age-related cognitive functioning. With increasing numbers of older adults required to remain in the workforce, it is important to be able to reliably predict future functional decline, as well as the individual advantages of cognitive training. Given the correlation between age-related decline and striatal dopaminergic function, we investigated whether eye blink rate (EBR), a non-invasive, indirect indicator of dopaminergic activity, could predict executive functioning (response inhibition, switching and working memory updating) as well as trainability of executive functioning in older adults. EBR was collected before and after a cognitive flexibility training, cognitive training without flexibility, or a mock training. EBR predicted working memory updating performance on two measures of updating, as well as trainability of working memory updating, whereas performance and trainability in inhibition and switching tasks could not be predicted by EBR. Our findings tentatively indicate that EBR permits prediction of working memory performance in older adults. To fully interpret the relationship with executive functioning, we suggest future research should assess both EBR and dopamine receptor availability among seniors.

Abstract Background Cognitive functions represent useful endophenotypes to identify the association between genetic variants and schizophrenia. In this sense, the NR4A2 gene has been implicated in schizophrenia and cognition in different animal models and clinical trials. We hypothesized that the NR4A2 gene is associated with working memory performance in schizophrenia. This study aimed to analyze two variants and the expression levels of the NR4A2 gene with susceptibility to schizophrenia, as well as to evaluate whether possession of NR4A2 variants influence the possible correlation between gene expression and working memory performance in schizophrenia. Methods The current study included 187 schizophrenia patients and 227 controls genotyped for two of the most studied NR4A2 genetic variants in neurological and neuropsychiatric diseases. Genotyping was performed using High Resolution Melt and sequencing techniques. In addition, mRNA expression of NR4A2 was performed in peripheral mononuclear cells of 112 patients and 118 controls. A group of these participants, 54 patients and 87 controls, performed the working memory index of the WAIS III test. Results Both genotypic frequencies of the two variants and expression levels of the NR4A2 gene showed no significant difference when in patients versus controls. However, patients homozygous for the rs34884856 promoter variant showed a positive correlation between expression levels and auditory working memory. Conclusions Our finding suggested that changes in expression levels of the NR4A2 gene could be associated with working memory in schizophrenia depending on patients’ genotype in a sample from a Mexican population.
