Abstract:

This Thesis aimed at investigating, by using the event-related potentials (ERPs) technique, some relevant aspects involved in human ability to read others’ emotions and in empathizing with others’ affective states. Social and affective neuroscience has largely studied faces and facial expressions since they represent relevant “pieces of information” in guiding individuals during interaction. Their importance is strictly related to the fact that they provide unique information about identity, gender, age, trustworthiness, and attractiveness, but they also convey emotions. In Chapter 1, I have

The aim of the current series of experiments was to further explore the boundary conditions of the recognition memory old/new effect in the context of the recognition/associative recall task (Rugg, Schloerscheidt, Doyle, Cox, & Patching, 1996). The study by Rugg et al. was replicated and extended by manipulating both the semantic relatedness between study items and the timing of recall. Eventrelated potentials (ERPs) were recorded from 17 scalp electrode sites during performance of a recognition/associative recall task. Forty participants were visually presented with four blocks of 50 word pai

Abstract:

What are the effects of non-balanced bilingualism on cognitive performance? And how do proficient, non-native speakers acquire and use lexical, syntactic and semantic information during sentence processing? Whilst there is growing research on these topics, there is no firm consensus on how to answer these questions. In the literature on cognitive effects of bilingualism, this lack of consensus has even resulted in radically opposing views and a heated debate. In this thesis, I seek to provide a balanced treatment of the literature and to address the above-mentioned questions by employing behav

Event-related potentials have been found to be a useful indicator of brain states and brain abnormality. The contingent negative variation, P300 and bereitschafts potential are well researched event-related potentials of particular interest. Many factors have to be considered in the design of measurement systems to record multiple channels of these signals accurately. The correlation between channels must be high and channel noise and distortion must be minimal, whilst the system as a whole must meet the requirements of the medical safety standards.

Abstract:

Background: The event related potential (ERP) is an important electrophysiological response to an internal or external stimulus on human body. In some studies, the ERP-based brain computer interface (BCI) systems were created in visual or auditory modality. However, in these type of BCIs, either the eyes or ears of the users are occupied when they are making a choice. It is not convenient to communicate with others. Thus, a somatosensory ERP based BCI can be developed to overcome this issue. According to this, the analysis of somatosensory ERP features is necessary to evaluate if somatosen

Abstract:

The electroencephalogram (EEG) reflects summated, slow post-synaptic potentials of cortical neurons. Sensory, motor or cognitive events (such as a fast-rising sensory stimulus, a brisk self-paced movement or a stimulus-triggered cognitive task) can elicit transient changes in the ongoing human EEG, called event-related potentials (ERPs). ERPs are widely used in clinical practice, and believed to reflect the activity of the sensory system activated by the stimulus (for example, laser-evoked potentials are used to substantiate the neuropathic nature of clinical pain conditions).

Over the last 30 or more years evidence has accumulated in favour of the view that memory is not a unitary faculty; rather, it can be subdivided into a num- ber of functionally independent subsystems. Whilst dividing memory phenomena into these distinct subsystems has undoubtedly advanced our understanding of memory as a whole, the approach of studying subsystems in isolation fails to address potential interactions between them. Over the last few decades there has been a gradual increase in the number of studies attempting to move be- yond dissociation by characterising functional interactions

Many questions remain unanswered regarding the intricacies of the human brain, especially with regard to the complexities of language processing. One essential component of human sentence processing is the ability to detect, decipher, and recover from errors in the interpretation of both verbal and written language. This process of repair of ungrammatical sentences and revision or reinterpretation of ambiguous sentences has been studied extensively in recent years. A variety of tools have been developed, including the use of event-related potentials (ERPs) in order to assess how language is pr

Abstract:

The phonological structure differs between languages. Human brain structure subserving speech perception is shaped through early exposure to and long-term experience with one’s native language, so that the sensitivity to specific acoustic cues that are relevant in that language develops. Such adaptive process of brain plasticity facilitates to recognize phonemes and capture prosodic signals correctly in the native language, whereas it augments difficulty to perceive some linguistic cues in foreign languages.

The ability to recognise an individual's affective state from their facial expression is crucial to human social interaction. However, understanding of facial expression recognition processes is limited because mounting evidence has revealed important differences between posed and genuine facial expressions of emotion.

Abstract:

It is a common practice to study the dynamics of sensory and cognitive processes using event-related potentials (ERPs) measured by placing electrodes on the scalp. These ERPs are very small in comparison with the on-going electroencephalogram (EEG) and are barely visible in the individual trials. Therefore, most ERP research relies on the identification of different waves after averaging several presentations of the same stimulus pattern. Although ensemble averaging improves the signal-to-noise-ratio, it implies a loss of information related to variations between the single-trials. In this the

Abstract:

The use of P3 as a diagnostic marker for schizophrenia was examined in a qualitative and quantitative review of the literature, as well as with an auditory discrimination task involving 21 schizophrenics, 16 patients with idiopathic Parkinson's disease and 50 matched controls. Although some studies have reported a lack of significant group differences between schizophrenics (or Parkinson's disease) and controls, both the quantitative reviews and the experimental studies suggest that this is probably due to a type 2 error. The band pass employed in experimental studies modifies results in that

Abstract:

A meta-analysis of event-related potential (ERP) studies between controls and high-OCD groups was conducted to examine whether there is a consistent relationship between differences in P300 amplitude and latency following exposure to OCD-related stimuli.After applying exclusion and inclusion criteria, 10 studies remained. The overall effect size for amplitudinal P300 differences was non-significant and results were heterogeneous, while the overall findings for latency were significant. There is therefore tentative evidence from this meta-analysis that reduced P300 latency is a neural correlate
