Unlocking the Beat: Dopamine and Eye Blink Response to Classical Music.

The present study examined music-induced dopamine release, as measured by a proxy measure of spontaneous eye blinks. Specifically, we explored the effects of uplifting and sombre tones in different sections of Vivaldi's to investigate the affective content of musical pieces within one composition. Seventeen participants listened to four concertos (Major modes: "Spring" and "Autumn", Minor modes: "Summer" and "Winter") and a silence condition while completing a three-stimulus odd-ball attention task.

The impact of a rosemary containing drink on event-related potential neural markers of sustained attention.

Background: Research suggests that the ingestion or aroma of rosemary enhances cognitive ability in both rodents and humans. However, how rosemary facilitates cognition and the precise therapeutic impacts on information processing remains unclear.

Hypothesis/purpose: This pilot study used the temporal precision of event-related potentials (ERPs) to examine the cognitive-enhancing benefits of a rosemary drink.

Age-related changes in ongoing thought relate to external context and individual cognition.

Understanding how age-related changes in cognition manifest in the real world is an important goal. One means of capturing these changes involves "experience sampling" participant's self-reported thoughts. Research has shown age-related changes in ongoing thought: e.

The impact of social isolation and changes in work patterns on ongoing thought during the first COVID-19 lockdown in the United Kingdom.

The COVID-19 pandemic led to lockdowns in countries across the world, changing the lives of billions of people. The United Kingdom's first national lockdown, for example, restricted people's ability to socialize and work. The current study examined how changes to socializing and working during this lockdown impacted ongoing thought patterns in daily life.

An EEG investigation of alpha and beta activity during resting states in adults with Williams syndrome.

Background: Williams syndrome (WS) is neurodevelopmental disorder characterised by executive deficits of attention and inhibitory processing. The current study examined the neural mechanisms during resting states in adults with WS in order to investigate how this subserves the attention and inhibitory deficits associated with the syndrome.

Method: Adopting electroencephalography (EEG) methodology, cortical electrical activity was recorded from eleven adults with WS aged 35 + years during Eyes Closed (EC) and Eyes Open (EO) resting states, and compared to that of thirteen typically developing adults matched for chronological age (CA) and ten typically developing children matched for verbal mental ability (MA).

Reduced semantic control in older adults is linked to intrinsic DMN connectivity.

Ageing provides an interesting window into semantic cognition: while younger adults generally outperform older adults on many cognitive tasks, knowledge continues to accumulate over the lifespan and consequently, the semantic store (i.e., vocabulary size) remains stable (or even improves) during healthy ageing.

Frogs' Legs Versus Roast Beef: How Culture Can Influence Mind-Wandering Episodes Across the Lifespan.

Numerous studies have captured the nature of mind-wandering and how it changes across the lifespan; however, the influence of culture has been neglected. This study investigated the joint effects of culture and age in a large scale online questionnaire-based survey of 308 adults over 18 years of age, both in France and the United Kingdom. To capture a profile of thinking style, self-report measures of mind-wandering frequency, mindfulness, mood, rumination, self-reflection, future thinking, depressive symptoms, and cognitive failures were gathered.

Patterns of on-task thought in older age are associated with changes in functional connectivity between temporal and prefrontal regions.

Humans spend a large proportion of their time engaged in thoughts unrelated to the task being performed, a tendency that declines with age. However, a clear neuro-cognitive account of what underlies this decrease is lacking. This study addresses the possibility that age-related changes in off-task thinking are correlated with changes in the intrinsic organisation of the brain.

The disentanglement of the neural and experiential complexity of self-generated thoughts: A users guide to combining experience sampling with neuroimaging data.

Human cognition is not limited to the processing of events in the external environment, and the covert nature of certain aspects of the stream of consciousness (e.g. experiences such as mind-wandering) provides a methodological challenge.

Daydream Believer: Rumination, Self-Reflection and the Temporal Focus of Mind Wandering Content.

Current research into mind-wandering is beginning to acknowledge that this process is one of heterogeneity. Following on from previous findings highlighting the role of self-focus during mind wandering, the present study aimed to examine individual differences in rumination and self-reflection and the impact such styles of self-focus may have on mind-wandering experiences. Thirty-three participants were required to complete the Sustained Attention Response Task (SART), aimed at inducing mind-wandering episodes, whilst also probing the content of thought in terms of temporal focus.

Impulsiveness, postprandial blood glucose, and glucoregulation affect measures of behavioral flexibility.

Behavioral flexibility (BF) performance is influenced by both psychological and physiological factors. Recent evidence suggests that impulsivity and blood glucose can affect executive function, of which BF is a subdomain. Here, we hypothesized that impulsivity, fasting blood glucose (FBG), glucose changes (ie, glucoregulation) from postprandial blood glucose (PBG) following the intake of a 15-g glucose beverage could account for variability in BF performance.

Glucose regulation and face recognition deficits in older adults: the role of attention.

The present study investigated the perceptual, attentional, and memory processes underlying face recognition deficits observed in older adults with impaired glucoregulation. Participants were categorized as good glucoregulators or poor glucoregulators on the basis of an oral glucose tolerance test. Using event-related potential (ERP) methodology, 23 participants (62-88 years) performed a 2-stimulus oddball task.

Retrieval and Monitoring Processes during Visual Working Memory: An ERP Study of the Benefit of Visual Semantics.

In this study, we examined electrophysiological indices of episodic remembering whilst participants recalled novel shapes, with and without semantic content, within a visual working memory paradigm. The components of interest were the parietal episodic (PE; 400-800 ms) and late posterior negativity (LPN; 500-900 ms), as these have previously been identified as reliable markers of recollection and post-retrieval monitoring, respectively. Fifteen young adults completed a visual matrix patterns task, assessing memory for low and high semantic visual representations.

An event related potential study of ihibitory and attentional control in Williams syndrome adults.

The primary aim of the current study was to employ event-related potentials (ERPs) methodology to disentangle the mechanisms related to inhibitory control in older adults with Williams syndrome (WS). Eleven older adults with WS (mean age 42), 16 typically developing adults (mean age 42) and 13 typically developing children (mean age 12) participated in the study. ERPs were recorded during a three-stimulus visual oddball task, during which participants were required to make a response to a rare target stimulus embedded in a train of frequent non-target stimuli.

Impaired Word and Face Recognition in Older Adults with Type 2 Diabetes.

Background And Aims: Older adults with type 2 diabetes mellitus (DM2) exhibit accelerated decline in some domains of cognition including verbal episodic memory. Few studies have investigated the influence of DM2 status in older adults on recognition memory for more complex stimuli such as faces. In the present study we sought to compare recognition memory performance for words, objects and faces under conditions of relatively low and high cognitive load.

Functional Living in Older Adults With Type 2 Diabetes: Executive Functioning, Dual Task Performance, and the Impact on Postural Stability and Motor Control.

Objective: Older adults with type 2 diabetes mellitus (DM2) experience accelerated age-related decline in some domains of cognition. The present study sought to investigate executive functioning and dual tasking capacities in this group.

Method: Older adults with DM2 and age-matched controls completed self-report measures assessing everyday activities, a comprehensive cognitive battery and more specific tasks assessing executive functioning, dual tasking, postural stability, and motor control.

Type 2 diabetes and memory: using neuroimaging to understand the mechanisms.

The most robust and frequently reported cognitive deficits in type 2 diabetes (DM2) are those that relate to memory. Behavioural research has identified a number of potential contributory physiological factors, including abnormalities in glucose metabolism, such as hyperglycaemia and hypoglycaemia. The impact of these mechanisms on memory has been further investigated through the use of both structural and functional neuroimaging.

Deeper processing is beneficial during episodic memory encoding for adults with Williams syndrome.

Previous research exploring declarative memory in Williams syndrome (WS) has revealed impairment in the processing of episodic information accompanied by a relative strength in semantic ability. The aim of the current study was to extend this literature by examining how relatively spared semantic memory may support episodic remembering. Using a level of processing paradigm, older adults with WS (aged 35-61 years) were compared to typical adults of the same chronological age and typically developing children matched for verbal ability.

Attentional lapse and inhibition control in adults with Williams Syndrome.

Research exploring cognitive processing associated with Williams Syndrome (WS) has suggested that executive functioning deficits exist across the developmental spectrum. Such executive functions include problem solving, planning, dividing attention and inhibiting responses. Within a framework of executive functions, the aim of the current study was to explore attentional lapse and inhibition skills in older adults with WS (n=20; aged 36-61 yr) and consider the implications of deficits within this group.

Glucose enhancement of event-related potentials associated with episodic memory and attention.

Previous studies have reported that increasing glycaemia by a glucose-containing drink enhances memory functioning. The aim of the present study was to extend this literature by examining the effects of glucose on episodic memory as well as attention processes, and to investigate associated event-related potential (ERP) markers. Fifteen minutes after treatment (25 g glucose or placebo drink), 35 participants performed an old/new recognition memory task and a Stroop colour naming task.

A familiar pattern? Semantic memory contributes to the enhancement of visuo-spatial memories.

In this study we quantify for the first time electrophysiological components associated with incorporating long-term semantic knowledge with visuo-spatial information using two variants of a traditional matrix patterns task. Results indicated that the matrix task with greater semantic content was associated with enhanced accuracy and RTs in a change-detection paradigm; this was also associated with increased P300 and N400 components as well as a sustained negative slow wave (NSW). In contrast, processing of the low semantic stimuli was associated with an increased N200 and a reduction in the P300.

The joys of spring.

This study used Vivaldi's Four Seasons, an extraordinary example of program music, to explore the consequence of music exposure on cognitive event-related potentials (ERPs). Seventeen participants performed a three-stimulus visual odd-ball task while ERPs were recorded. Participants were required to differentiate between a rare target stimulus (to elicit a memory updating component; P3b), a rare novel stimulus (to elicit a novelty attention component; P3a), and a frequent nontarget stimulus.

Preliminary evidence that glucose ingestion facilitates prospective memory performance.

Previous research has found that the ingestion of glucose boosts task performance in the memory domain (including tasks tapping episodic, semantic, and working memory). The present pilot study tested the hypothesis that glucose ingestion would enhance performance on a test of prospective memory. In a between-subjects design, 56 adults ranging from 17 to 80 years of age performed a computerized prospective memory task and an attention (filler) task after 25 g of glucose or a sweetness-matched placebo.

Absorbed in thought: the effect of mind wandering on the processing of relevant and irrelevant events.

This study used event-related potentials to explore whether mind wandering (task-unrelated thought, or TUT) emerges through general problems in distraction, deficits of task-relevant processing (the executive-function view), or a general reduction in attention to external events regardless of their relevance (the decoupling hypothesis). Twenty-five participants performed a visual oddball task, in which they were required to differentiate between a rare target stimulus (to measure task-relevant processes), a rare novel stimulus (to measure distractor processing), and a frequent nontarget stimulus. TUT was measured immediately following task performance using a validated retrospective measure.
