The SPAARS approach: implications for psychopathy
Neha Khetrapal
Poiesis & Praxis , 2009, DOI: 10.1007/s10202-008-0059-x
Abstract: SPAARS (Schematic, Propositional, Analogical and Associative Representational Systems) est un modèle multi-niveaux du traitement de l’émotion et des cognitions, proposé par Power et Dalgleish (1997). Il comporte quatre niveaux différents de représentation. Selon SPAARS, les émotions d’un individu sont basées sur ses propres attentes, l’image mentale se transformant en réalité. Les émotions primaires comportent une composante innée et peuvent être éclipsées automatiquement puisqu’elles ont déjà été appréciées dans le passé évolutif de l’individu. Ce modèle propose que l’émotion se produise à travers deux voies. Il nous offre une approche utile à la compréhension des émotions autant primaires que complexes. Cette théorie peut également nous donner une explication des désordres émotionnels, ainsi que leur traitement par l’élaboration de nouvelles interventions thérapeutiques. La présente étude utilise SPAARS pour la compréhension de la psychopathie, aussi appelée désordre de l’empathie (une émotion complexe). Cette approche nous offre un nouveau point de vue sur les psychopathes. Elle suggère que la psychopathie se développe suite à un problème générant l’émotion primaire de la tristesse ou celle complexe de l’empathie ou bien une combinaison des deux. Le traitement adapté dépendra de la nature sous-jacente du problème.
Achieving common grounds in communication via interfaces: a role of spatial frames for reference
Neha Khetrapal
Poiesis & Praxis , 2010, DOI: 10.1007/s10202-010-0084-4
Abstract: The current paper argues for synchronising spatial frames of reference for achieving effective multiparty communication in collaborative virtual environments. Synchronising nonverbal behaviour from different modalities is an important step for simulating face-to-face-interaction where all nonverbal cues are available. Such synchronisation also serves as an effective basis for building multimodal interfaces especially if these have to be deployed for multiparty communication. It is argued that common spatial reference frames are helpful in coordinating different points of attention and facilitating work by serving as the springboard for joint attention among members of the team. Consequently, it is desirable to aim for such common grounds and not just focus on coordinating disjointed virtual spaces for facilitating decision-making by reducing felt collaborative effort. Implementing the synchronisation of spatial reference frames for modern technologies thus serves dual purposes by achieving common grounds in communication and maintaining autonomy of each member at the same time. Towards this end, the current paper proposes the concept of decentred egocentric frame, the origin of which is one’s own body and the spatial relation between two objects is defined with respect to this origin. This frame seems to be important for separating each member’s focus from his own body (self/activities) and also helps in coordinating one’s focus with those of the others whether interacting verbally or nonverbally. This is an important conceptual development as the proposed classification is hypothesised to function in a similar manner across different sensory modalities. The paper concludes with issues on implementation and other future conceptual developments.
Psychopathy and a Model for Disturbed Affective Consciousness
Khetrapal, Neha
Suma Psicológica , 2008,
Abstract: This article deals with the interaction of emotion and consciousness. It focuses on the perception of fearful stimuli and how such a perception can have implications for psychopathy. Amygdala has been found to be lesioned in the disorder and this compromise of integrity leads to deficits in fear perception, moral socialization and curtailing of aggression. This in turn leads to deficits in adaptive behavior as amygdala is responsible for influencing motor and perceptual responses in response to a fearful stimulus. Amygdala also plays an important role in bringing a fearful stimulus, detected at the attentional periphery, to the focus of attention and awareness so that it can receive enhanced processing which is found to be eficient in psychopathy. This role is supported by its connectivity to different cortical and subcortical areas. Hence this article provides an emphasis on the disturbed affective consciousness of psychopathy and its role in adaptive behavior deficits
Overlap of Autism and Seizures: Understanding Cognitive Comorbidity
Khetrapal Neha
Mens Sana Monographs , 2010,
Abstract: This article introduces the concept of ′cognitive comorbidity,′ which lays emphasis on common cognitive deficits that cut across different disorders. The concept is illustrated with the help of two commonly reported overlapping conditions (autism and epilepsy). It is further explained by concentrating on two important cognitive processes of facial emotional recognition and emotional memory, shown to be compromised in both conditions; and their underlying neural substrates. Cognitive comorbidity is then contrasted with ′comorbidity,′ a term which is more commonly used for describing cognitive disorders. The paper closes by providing directions for rehabilitative and theoretical efforts that could be inspired by the newly introduced concept.
The framework for disturbed affective consciousness in autism
Neha Khetrapal
Neuropsychiatric Disease and Treatment , 2008,
Abstract: Neha KhetrapalCentre for Behavioural and Cognitive Sciences, University of Allahabad, Allahabad, IndiaAbstract: The current article explores the implication of the interaction of emotion and consciousness for autism. The framework that is proposed for the disorder explains that the compromised functional integrity of the amygdala is the root cause of disturbed affective consciousness. Amygdala, with its connections to various cortical and subcortical regions, helps detect a fearful facial expression at the attentional periphery and make it the focus of attention and awareness for enhanced processing. The conscious life of autistics with respect to affective objects can thus be very different from that of normal people, which leads them to perceive the world differently. They process fearful stimuli the way normal controls perceive common objects by activating areas responsible for feature based analysis rather than the amygdala and other connected areas. Conscious perception of such stimuli is important for appropriate development of emotion concepts, something that autistics lack, thus leading to impairment in the awareness of one’s own emotions especially within the negative spectrum with a prominent position for fearful stimuli. Thus the interaction of emotion with consciousness is ripe for investigation and can help to throw light on the mental life of autistics.Keywords: emotion, amygdala, visual awareness, fear processing
The Early Attachment Experiences are the Roots of Psychopathy
Neha Khetrapal
Interpersona : An International Journal on Personal Relationships , 2009,
Abstract: This review proposes the ‘attachment and the deficient hemispheric integration hypothesis’ as explanation for psychopathy. The hypothesis states that since secure attachment to the parents is essential for the proper development of both the hemispheres in children, psychopaths with histories of neglect and abuse are unable to develop efficient interaction of both the hemispheres, important for emotional processing and regulation. Various studies have shown that without an efficient interaction between the two hemispheres psychopaths fail to perform adequately on tasks that require both language abilities and non-verbal emotional processing. The hypothesis also explains why psychopaths will perform inefficiently in conditions that selectively prime the left hemisphere resources as these people would have learnt to rely more on the language based mode of this hemisphere. The childhood of psychopaths is marked by insecure attachment with their parents where the parents fail to respond to the needs of the pre-verbal infant thus leading to improper development of the right hemisphere abilities, one of which is decoding and showing appropriate non-verbal emotional signals resembling a pattern shown by the parents. The hypothesis is useful in explaining different findings on laterality in psychopathy as well as answering the nature-nurture debate of the disorder. Research carried out under the proposed framework can be helpful in understanding the nature of the disorder which will be ultimately useful in the prevention of its full blown manifestation.
Boundary Term Contribution to the Volume of a Small Causal Diamond
Surbhi Khetrapal,Sumati Surya
Physics , 2012, DOI: 10.1088/0264-9381/30/6/065005
Abstract: In his calculation of the spacetime volume of a small Alexandrov interval in 4 dimensions Myrheim introduced a term which he referred to as a surface integral [1]. The evaluation of this term has remained opaque and led subsequent authors to evaluate the volume using other techniques [2]. It is the purpose of this work to demystify this integral. We point out that it arises from the difference in the flat spacetime volumes of the curved and flat spacetime intervals. An explicit evaluation using first order degenerate perturbation theory shows that it adds a dimension independent factor to the flat spacetime volume as the lowest order correction. Our analysis admits a simple extension to a more general class of integrals over the same domain. Using a combination of techniques we also find that the next order correction to the volume vanishes.
Exploring the Factors that Affect the Choice of Destination for Medical Tourism  [PDF]
Neha Singh, Harsimran Gill
Journal of Service Science and Management (JSSM) , 2011, DOI: 10.4236/jssm.2011.43037
Abstract: Medical Tourism has become one of the latest trends in the tourism industry which has been and has the potential to continue growing exponentially every year. More travelers than ever before are now travelling abroad to get high quality medical treatments for less cost. The purpose of my study is to explore the interest in US travelers in medical tourism. Results from the survey indicated that “competent doctors”, “high quality medical treatment facility”, and “prompt medical treatment when needed” where the top three factors before deciding whether or not to take a trip abroad. The results will be useful to businesses that are either directly or indirectly involved with this industry, such as insurance companies, credit card companies, travel agencies, hotels, food and beverage companies, medical facilities and services, and spas.
Energy Saving in WSN with Directed Connectivity  [PDF]
Neha Deshpande, Arvind Shaligram
Wireless Sensor Network (WSN) , 2013, DOI: 10.4236/wsn.2013.56015
Abstract:

Wireless Sensor Networks have been implemented in many indoor applications such as offices, hospitals, laboratories for monitoring the parameters such as temperature, humidity etc. Most of the applications have used omnidirectional antennas. In randomly deployed ad hoc wireless sensor networks, this may be useful to achieve coverage and connectivity with unknown neighbors. In case of deterministic deployments such as in case of food grain storages where locations of the sensor nodes are mostly fixed, the main challenges are unstable and vacillating conditions in the godowns during loading and unloading of sacs as well as unpredictable changes in climate. Most of the commercial motes generally use omnidirectional antennas. Energy overheads increase considerably with omnidirectional antennas. Directivity increases energy saving but may be at the cost of redundancy. This paper is mainly focused on the energy advantage in ad hoc wireless sensor networks deployed in large food grain storages and energy overheads required for obtaining certain level of redundancy using directional antennas. Finally, we conclude that energy advantage can be achieved even if we overcome redundancy to certain extent.

Extracting Significant Patterns for Oral Cancer Detection Using Apriori Algorithm  [PDF]
Neha Sharma, Hari Om
Intelligent Information Management (IIM) , 2014, DOI: 10.4236/iim.2014.62005
Abstract:

Presently, no effective tool exists for early diagnosis and treatment of oral cancer. Here, we describe an approach for cancer detection and prevention based on analysis using association rule mining. The data analyzed are pertaining to clinical symptoms, history of addiction, co-morbid condition and survivability of the cancer patients. The extracted rules are useful in taking clinical judgments and making right decisions related to the disease. The results shown here are promising and show the potential use of this approach toward eventual development of diagnostic assay and treatment with sufficient support and confidence suitable for detection of early-stage oral cancer.
