Spotlight on the Survival Processing Advantage': An FNIRS Study on Adaptive Memory
International audience; In the present study, participants had to rate words for their relevance in an ancestral survival scenario (e.g., is bottle relevant in the fictious scenario of being stranded in the grasslands of a foreign land without basic supplies) and for their pleasantness (e.g., is bottle a pleasant word?). A distractor task lasting a few minutes followed and the participants were then tested on their recall of the words. We used fNIRS to bilaterally monitor the dorsolateral-prefrontal cortex (DLPFC, known to be involved in strategic encoding) during the processing of verbal material in these two deep encoding situations. At the behavioral level, we replicated the survival pro…
Music and the Aging Brain
In a society that is getting considerably older, it becomes important to identify potential mechanisms promoting successful aging to prevent, limit, and rehabilitate cognitive and emotional impairments typical of normal or pathological aging. Music is a powerful stimulus able to modulate widespread brain activations. Recent research has increasingly considered music as a promising, stimulating training and rehabilitation tool for improving cognition and promoting well-being and social connection. This chapter provides an overview of recent research investigating music and aging. It first focuses on the effects of music in normal aging, both in terms of musical expertise and simple musical e…
The positive effect of music on source memory
Several studies have investigated how to improve episodic memory performance by manipulating the factors that are crucial for successful encoding. There is an ongoing debate about whether a complex stimulus such as music can improve memory, and in particular memory for words, rather than interfere with correct encoding of information. Therefore, the present study aims to investigate whether verbal episodic memory can be improved by background context of instrumental music. Twenty young adults were asked to memorize different lists of words presented against a background of music, environmental sounds or silence. Their episodic memory performance was then tested in terms of item and source …
The Influence of Music on Prefrontal Cortex during Episodic Encoding and Retrieval of Verbal Information: A Multichannel fNIRS Study.
Music can be thought of as a complex stimulus able to enrich the encoding of an event thus boosting its subsequent retrieval. However, several findings suggest that music can also interfere with memory performance. A better understanding of the behavioral and neural processes involved can substantially improve knowledge and shed new light on the most efficient music-based interventions. Based on fNIRS studies on music, episodic encoding, and the dorsolateral prefrontal cortex (PFC), this work aims to extend previous findings by monitoring the entire lateral PFC during both encoding and retrieval of verbal material. Nineteen participants were asked to encode lists of words presented with eit…
Less Effort, Better Results: How Does Music Act on Prefrontal Cortex in Older Adults during Verbal Encoding? An fNIRS Study
Several neuroimaging studies of cognitive aging revealed deficits in episodic memory abilities as a result of prefrontal cortex (PFC) limitations. Improving episodic memory performance despite PFC deficits is thus a critical issue in aging research. Listening to music stimulates cognitive performance in several non-purely musical activities (e.g., language and memory). Thus, music could represent a rich and helpful source during verbal encoding and therefore help subsequent retrieval. Furthermore, such benefit could be reflected in less demand of PFC, which is known to be crucial for encoding processes. This study aimed to investigate whether music may improve episodic memory in older adult…
