Effects of Daytime Electric Light Exposure on Human Alertness and Higher Cognitive Functions: A Systematic Review

Mushfiqul Anwar Siraji; Vineetha Kalavally; Alexandre Schaefer et al.

Frontiers in Psychology, Vol. 12 · 2022 · English · DOAJ Scopus

This paper reports the results of a systematic review conducted on articles examining the effects of daytime electric light exposure on alertness and higher cognitive functions. For this, we selected 59 quantitative research articles from 11 online databases. The review protocol was registered with…

Relative Changes from Prior Reward Contingencies Can Constrain Brain Correlates of Outcome Monitoring

Faisal Mushtaq; Gijsbert Stoet; Amy Rachel Bland et al.

PLoS ONE, Vol. 8 No. 6 · 2013 · English · PLOS Scopus

It is well-known that the affective value of an environment can be relative to whether it reflects an improvement or a worsening from a previous state. A potential explanation for this phenomenon suggests that relative changes from previous reward contingencies can constrain how brain monitoring…

The Relationship Between Socioeconomic Status and Scalp Event-Related Potentials: A Systematic Review

Hiran Perera-W.A.; Khazriyati Salehuddin; Rozainee Khairudin et al.

Frontiers in Human Neuroscience, Vol. 15 · 2021 · English · DOAJ Scopus

Several decades of behavioral research have established that variations in socioeconomic status (SES) are related to differences in cognitive performance. Neuroimaging and psychophysiological techniques have recently emerged as a method of choice to better understand the neurobiological processes…

The Feedback-Related Negativity and the P300 Brain Potential Are Sensitive to Price Expectation Violations in a Virtual Shopping Task

Alexandre Schaefer; Luciano G. Buratto; Nobuhiko Goto et al.

PLOS ONE, Vol. 11 No. 9 · 2016 · English · PLOS Scopus

A large body of evidence shows that buying behaviour is strongly determined by consumers’ price expectations and the extent to which real prices violate these expectations. Despite the importance of this phenomenon, little is known regarding its neural mechanisms. Here we show that two patterns of…

The Effects of a Distracting N -Back Task on Recognition Memory Are Reduced by Negative Emotional Intensity

Luciano G. Buratto; Claire L. Pottage; Charity Brown et al.

PLoS ONE, Vol. 9 No. 10 · 2014 · English · PLOS Scopus

Memory performance is usually impaired when participants have to encode information while performing a concurrent task. Recent studies using recall tasks have found that emotional items are more resistant to such cognitive depletion effects than non-emotional items. However, when recognition tasks…

Feedback-related potentials in a gambling task with randomised reward

Faisal Mushtaq; Pablo Puente Guillen; Richard M. Wilkie et al.

Data in Brief, Vol. 6 · 2016 · English · DOAJ Scopus

Event-related potentials (ERPs) time-locked to decision outcomes are reported. Participants engaged in a gambling task (see [1] for details) in which they decided between a risky and a safe option (presented as different coloured shapes) on each trial (416 in total). Each decision was associated…

The Effects of Adult Ageing and Culture on the Tower of London Task

Louise H. Phillips; Louisa Lawrie; Alexandre Schaefer et al.

Frontiers in Psychology, Vol. 12 · 2021 · English · DOAJ Scopus

Planning ability is important in everyday functioning, and a key measure to assess the preparation and execution of plans is the Tower of London (ToL) task. Previous studies indicate that older adults are often less accurate than the young on the ToL and that there may be cultural differences in…

Multiple group membership and executive function in a socioeconomically diverse sample

Nobuhiko Goto; Sony Kusumasondjaja; Fandy Tjiptono et al.

Scientific Reports, Vol. 14 No. 1 · 2024 · English · DOAJ Scopus

Abstract Belonging to multiple groups is an important feature of our social lives. However, it is largely unknown if it is related to individual differences in cognitive performance. Given that changing self-identities linked to each group requires cognitive operations on knowledge bases associated…

Frontal theta brain activity varies as a function of surgical experience and task error

Faisal Mushtaq; Mark A Mon-Williams; Michael Manogue et al.

BMJ Surgery, Interventions, & Health Technologies, Vol. 2 No. 1 · 2020 · English · DOAJ

Objective Investigations into surgical expertise have almost exclusively focused on overt behavioral characteristics with little consideration of the underlying neural processes. Recent advances in neuroimaging technologies, for example, wireless, wearable scalp-recorded electroencephalography…

Self-help digital mental health intervention in improving burnout and mental health outcomes among healthcare workers: A narrative review

Lwin M. Aye; Min M. Tan; Alexandre Schaefer et al.

Digital Health, Vol. 10 · 2024 · English · DOAJ Scopus

Background Healthcare workers face burnout from high job demands and prolonged working conditions. While mental health services are available, barriers to access persist. Evidence suggests digital platforms can enhance accessibility. However, there is a lack of systematic reviews on the…

A systematic review on the relationship between socioeconomic conditions and emotional disorder symptoms during Covid-19: unearthing the potential role of economic concerns and financial strain

Jee Kei Chan; Aleya A. Marzuki; Samira Vafa et al.

BMC Psychology, Vol. 12 No. 1 · 2024 · English · DOAJ Scopus

Abstract Background Covid-19 has disrupted the lives of many and resulted in high prevalence rates of mental disorders. Despite a vast amount of research into the social determinants of mental health during Covid-19, little is known about whether the results are consistent with the social gradient…

Can Brain Waves Really Tell If a Product Will Be Purchased? Inferring Consumer Preferences From Single-Item Brain Potentials

Nobuhiko Goto; Xue Li Lim; Dexter Shee et al.

Frontiers in Integrative Neuroscience, Vol. 13 · 2019 · English · DOAJ Scopus

Recent research has shown that event-related brain potentials (ERPs) recorded while participants view lists of different consumer goods can be modulated by their preferences toward these products. However, it remains largely unknown whether ERP activity specific to a single consumer item can be…
