Cultural Experiences

Chapter 2 introduces the concept of cultural learning and its function in the transmission of cultural knowledge over generations, and the construction of new cultural beliefs/values and behavioral scripts. It examines brain activity that is engaged in differential processing of culturally familiar and unfamiliar information by reviewing functional magnetic resonance imaging and event-related potential studies of neural activity involved in the processing of gesture, music, brand, and religious knowledge. Long-term cultural experiences give rise to specific neural mechanisms in the human brain that deal with culturally familiar information in multiple neural circuits underlying the inference of mental states and reward, for example. The unique neural mechanisms underlying culturally familiar stimuli provide a default mode of neural processing of culturally familiar information received in daily life.

The Right

Depression is often associated with profound social and interpersonal functioning impairments. Negative interpersonal experiences may lead depressed individuals to withdraw from social interaction, which may in turn exacerbate the depression state (Rippere, 1980). As a result, it is of theoretical and clinical importance to understand the mechanisms underlying these social deficits. Researchers have applied the theory‐of‐mind framework to better understand the impaired social functioning in depressed individuals. Theory of mind refers to the everyday ability to attribute mental states (i.e., beliefs, desires, emotions) to others to both understand and predict their behaviour (Wellman, 1990). Research has found that individuindividuals with dysphoria (i.e. elevated scores on a measure of depression symptoms, but not necessarily a diagnosis of clinical depression) demonstrate enhanced mental state judgments (Harkness, Sabbagh, Jacobson, Chowdrey, & Chen, 2005). This study will determine neural mechanisms that may underlie this phenomenon by examining whether differences in brain activity exist between dysphoric and nondysphoric groups during mental states decoding. I will record electrophysiological data while participants are judging the mental states from pictures of eyes. Based on previous research (Sabbagh, Moulson, & Harkness, 2004), I anticipate that mental state decoding will be associated with the right inferior frontal and right anterior temporal regions of the brain. Furthermore, I hypothesize that dysphoric individuals will have greater activations in these brain regions and make significantly more accurate judgments than nondysphoric individuals when making mental state judgments.

Functional Brain Activity

Chapter 6 examines the effects of cultural priming on cognition and brain activity by reviewing brain imaging evidence that temporary shifts of cultural knowledge systems toward independence or interdependence can significantly modulated brain activities involved in pain-related sensory processing, visual perception, self-face recognition and self-reflection, monetary reward, empathy, and a resting state. These findings provide evidence for a causal relationship between cultural belief/value and functional organization of the human brain. The findings further suggest that functional brain activity is constrained by both the sustained cultural frameworks formulated during long-term cultural experiences and the transient cultural frameworks induced by short-term exposure to cultural values.

Abstract The desire for retaliation is a common response across a majority of human societies. However, the neural mechanisms underlying aggression and retaliation remain unclear. Previous studies on social intentions are confounded by low-level response related brain activity. Using an EEG-based brain-computer interface (BCI) combined with the Chicken Game, our study examined the neural dynamics of aggression and retaliation after controlling for nonessential response related neural signals. Our results show that aggression is associated with reduced alpha event-related desynchronization (ERD), indicating reduced mental effort. Moreover, retaliation and tit-for-tat strategy use are also linked with smaller alpha-ERD. Our study provides a novel method to minimize motor confounds and demonstrates that choosing aggression and retaliation is less effortful in social conflicts.

Pain, whether caused by physical injury or social rejection, is an inevitable part of life. These two types of pain—physical and social—may rely on some of the same behavioral and neural mechanisms that register pain-related affect. To the extent that these pain processes overlap, acetaminophen, a physical pain suppressant that acts through central (rather than peripheral) neural mechanisms, may also reduce behavioral and neural responses to social rejection. In two experiments, participants took acetaminophen or placebo daily for 3 weeks. Doses of acetaminophen reduced reports of social pain on a daily basis (Experiment 1). We used functional magnetic resonance imaging to measure participants’ brain activity (Experiment 2), and found that acetaminophen reduced neural responses to social rejection in brain regions previously associated with distress caused by social pain and the affective component of physical pain (dorsal anterior cingulate cortex, anterior insula). Thus, acetaminophen reduces behavioral and neural responses associated with the pain of social rejection, demonstrating substantial overlap between social and physical pain.

Compared with event-related potential (ERP) which is widely used in psychology research, functional near-infrared imaging (fNIRI) is a new technique providing hemodynamic information related to brain activity, except for electrophysiological signals. Here, we use both these techniques to study ocular attention. We conducted a series of experiments with a classic paradigm of ocular nonselective attention, and monitored responses with fNIRI and ERP respectively. The results showed that fNIRI measured brain activations in the left prefrontal lobe, while ERPs showed activation in frontal lobe. More importantly, only with the combination measurements of fNIRI and ERP, we were then able to find the pinpoint source of ocular nonselective attention, which is in the left and upper corner in Brodmann area 10. These results demonstrated that fNIRI is a reliable technique in psychology, and the combination of fNIRI and ERP can be promising to reveal more information in the research of brain mechanism.

The Brain

A fundamental characteristic of spontaneous brain activity is coherent oscillations covering a wide range of frequencies. Interestingly, these temporal oscillations are highly correlated among spatially distributed cortical areas forming structured correlation patterns known as the resting state networks, although the brain is never truly at “rest.” Here, we introduce the concept of harmonic brain modes—fundamental building blocks of complex spatiotemporal patterns of neural activity. We define these elementary harmonic brain modes as harmonic modes of structural connectivity; that is, connectome harmonics, yielding fully synchronous neural activity patterns with different frequency oscillations emerging on and constrained by the particular structure of the brain. Hence, this particular definition implicitly links the hitherto poorly understood dimensions of space and time in brain dynamics and its underlying anatomy. Further we show how harmonic brain modes can explain the relationship between neurophysiological, temporal, and network-level changes in the brain across different mental states ( wakefulness, sleep, anesthesia, psychedelic). Notably, when decoded as activation of connectome harmonics, spatial and temporal characteristics of neural activity naturally emerge from the interplay between excitation and inhibition and this critical relation fits the spatial, temporal, and neurophysiological changes associated with different mental states. Thus, the introduced framework of harmonic brain modes not only establishes a relation between the spatial structure of correlation patterns and temporal oscillations (linking space and time in brain dynamics), but also enables a new dimension of tools for understanding fundamental principles underlying brain dynamics in different states of consciousness.

In this increasingly interconnected epoch, the teaching of English as a Foreign Language (EFL) along with culture that is considered as a fifth skill has become inevitable. Therefore, EFL teachers are impelled to introduce cultural instruction in their classes. They are then advised to combine the teaching of language skills with the foreign culture because it prepares their learners to behave successfully in intercultural encounters, gain solid cultural knowledge, overcome cultural obstacles, and promote their cultural awareness. The main questions addressed in this research focus on the inclusion of the cultural component in language subjects’ syllabuses, and the type of teaching strategies that can ameliorate the status of cultural instruction. This study points out the key importance of implementing intercultural information in EFL contexts founded on a case study undertaken at the University of Oran 2 in Algeria. This paper targeted a group of Master II students by using an array of data collection means including a questionnaire given to the learners, an interview done with the teachers, and classroom observation sessions carried out by the researchers. The major aims of this work were to verify the learners’ perceptions of cultural learning, and outfit students with core foundations of culture. The results demonstrated that the incorporated teaching techniques have enriched the students’ cultural understanding and intensified their linguistic adeptnesses. It is suggested that these teaching initiatives can aid learners be compassionate, understandable, and tolerant human beings.

Exciting Possibility

Brain Computer Interface (BCI) methods have received a lot of attention in the past several decades, owing to the exciting possibility of computer-aided communication with the outside world. Most BCIs allow users to control an external entity such as games, prosthetics, musical output etc. or are used for offline medical diagnosis processing. Most BCIs that provide neurofeedback, usually categorize the brainwaves into mental states for the user to interact with. Raw brainwave interaction by the user is not usually a feature that is readily available for a lot of popular BCIs. If there is, the user has to pay for or go through an additional process for raw brain wave data access and interaction. BSoniq is a multi-channel interactive neurofeedback installation which, allows for real-time sonification and visualization of electroencephalogram (EEG) data. This EEG data provides multivariate information about human brain activity. Here, a multivariate event-based sonification is proposed using 3D spatial location to provide cues about these particular events. With BSoniq, users can listen to the various sounds (raw brain waves) emitted from their brain or parts of their brain and perceive their own brainwave activities in a 3D spatialized surrounding giving them a sense that they are inside their own heads.
