Event Based

This article presents a logical formalization of the emotional appraisal theory, i.e., it formalizes the cognitive process of evaluation that elicits an emotion. This formalization is psychologically grounded on the OCC cognitive model of emotions. More specifically, we are interested in event-based emotions, i.e., emotions that are elicited by the evaluation of the consequences of an event that either happened or will happen. The formal modelling presented here is based on the AfPL Probabilistic Logic, a BDI-like probabilistic modal logic, which allows our model to verify whether the variables that determine the elicitation of emotions achieved the necessary threshold or not. The proposed logical formalization aims at addressing how the emotions are elicited by the agent cognitive mental states (desires, beliefs and intentions), and how to represent the intensity of the emotions. These are important initial points in the investigation of the dynamic interaction among emotions and other mental states.

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.

The Brain

Humans perform activities collaboratively or individually, and these activities, more often than not, involve both physical and mental processes. However, irrespective of whether individual or collective functioning, knowledge creation is a personal experience. Nevertheless, the general tenet of this paper is that knowledge is created in a human’s mind and resides in the head. Hence, it posits that knowledge creation is cognitive (associated with the neurological structures of the brain) and psychological (involving consciousness)—a psycho-cognitive process. This study thus employs a “Cognaction” mechanism that is based on the assumptions captured below. The mechanism premised that the human cognitive chamber consists of 3C modes of comprehension (for interpreting stimuli transmitted to the brain by sensory organs), contextualisation (for mindful connecting of chunks to existing schemas), and conceptualisation (for evaluative reflection in a manner that leads to drawing inference and building themes or new concepts). It demonstrates that as diverse skill sets are applied to a task, they generate varieties of effects and outcomes. The outcomes though are distinctive and at the same time are cospecialised. Thus, the psycho-cognitive perspective demonstrates knowledge creation as a cocreation process and sees knowledge as a mix of cocreated, cognitive structures. In view of these, the study provides the missing explanation on how the knowledge archetypes emerged. And it provides the missing link between the belief that “knowledge is created in the head” and knowledge creation theory.

Cognitive Information

Autonomous agents (AAs) are designed to embody the natural intelligence by incorporating cognitive mechanisms that are applied to evaluate stimuli from an emotional perspective. Computational models of emotions (CMEs) implement mechanisms of human information processing in order to provide AAs for a capability to assign emotional values to perceived stimuli and implement emotion-driven behaviors. However, a major challenge in the design of CMEs is how cognitive information is projected from the architecture of AAs. This article presents a cognitive model for CMEs based on appraisal theory aimed at modeling AAs' interactions between cognitive and affective processes. The proposed scheme explains the influence of AAs' cognition on emotions by fuzzy membership functions associated to appraisal dimensions. The computational simulation is designed in the context of an integrative framework to facilitate the development of CMEs, which are capable of interacting with cognitive components of AAs. This article presents a case study and experiment that demonstrate the functionality of the proposed models.

Process Level

A cognitive process analysis and modeling approach to task analysis is described in the context of Project Nemo, a research effort aimed at explicating situation assessment behavior in commanders of nuclear powered attack submarines. The approach is structured around the rationality and problem space principles outlined in Card, Moran and Newell (1983). The process analysis phases involve characterizing the task domain as well as the subject's goals, operators, and knowledge. The modeling phases involves instantiating the elements from the process analysis phases into a runnable computational cognitive model. The behavior of this model is then judged against a standard, such as expert judgment or the commander's behavior, in order to evaluate the sufficiency of the cognitive process analysis. Unlike conventional task analysis methods, this approach enables the analyst not only to describe task behavior at a detailed cognitive process level, but to evaluate the precision of that description.

Modelling Error

Evolutionarily stable strategy (ESS) models of biological signalling are important because the intimate coevolution of signalling and receiving strategies is complicated. Tentative results from a numerical study of error-prone signalling show the value of formal modelling. Error in perception can create discreteness in the distribution of signals produced, and so observed discreteness in nature may call for no more complicated explanation. Further developments in the theory of signalling may include a link with theories of aggression such as the sequential assessment game. The technical device of a ‘scratch space’ may allow a natural development of ‘two-way’ information games in which each contestant plays the roles of signaller and receiver simultaneously. This device may also incidentally derive mental states from purely strategic considerations.

Emotion Models

Logical formalization of emotions moves forward and develops more widely accepted and clearly defined emotion models. However, there is little quantitative analysis of emotions based on modal logic. We put forward a logic LEI to represent quantitative belief, preference and disgust. Then, event-based emotions, agent-based emotions in OCC model and their intensity are formalized by the logic.

Within the theoretical frameworks of cognitive linguistics and cognitive construction grammar, this papertakes the pair of a WH-question and one of its answers in contemporary spoken English as the research object and regards such pairs as WH-dialogic constructions. In this study we construct an Event-based Schema-Instance Cognitive Model (ESI model) to analyze the cognitive-functional properties of this category of dialogic constructions. The discoursal expansion and textual cohesion in discourse achieved through the application of such dialogic constructions indicate that the usage of WH-dialogic constructions is one of the basic cognitive strategies for human beings to construe the objective world.

Longitudinal Assessment

A simplified cognitive model is proposed to assess the dynamic aspect of consumer satisfaction/dissatisfaction in consecutive purchase behavior. Satisfaction is found to have a significant role in mediating intentions and actual behavior for five product classes that were analyzed in the context of a three-stage longitudinal field study. The asymmetric effect found demonstrates that repurchase of a given brand is affected by lagged intention whereas switching behavior is more sensitive to dissatisfaction with brand consumption. An attempt to predict repurchase behavior on the basis of the investigated cognitive variables yielded weak results. However, repurchase predictions were improved when the model was extended to a multipurchase setting in which prior experience with the brand was taken into account.

Embodied Appraisals and Non-emotional StatesWe present the embodied appraisal theory of emotions and show how it handles a variety of intuitions we hold about affective states. While appreciating its integrative potential, we point out possible difficulties that it might face from further investigation of embodied non-emotional states. Following Darwin and his work on the expression of emotions, we suggest that some obviously non-emotional mental states comply with the criteria set by Prinz's theory. Therefore it is doubtful whether his definition of emotions is correct and whether perceptual approaches are useful in explicating the nature of emotion types.

BackgroundVirtual reality provides a means of studying paranoid thinking in controlled laboratory conditions. However, this method has not been used with a clinical groupAimsTo establish the feasibility and safety of using virtual reality methodology in people with an at-risk mental state and to investigate the applicability of a cognitive model of paranoia to this groupMethodTwenty-one participants with an at-risk mental state were assessed before and after entering a virtual reality environment depicting the inside of an underground trainResultsVirtual reality did not raise levels of distress at the time of testing or cause adverse experiences over the subsequent week. Individuals attributed mental states to virtual reality characters including hostile intent. Persecutory ideation in virtual reality was predicted by higher levels of trait paranoia, anxiety, stress, immersion in virtual reality, perseveration and interpersonal sensitivityConclusionsVirtual reality is an acceptable experimental technique for use with individuals with at-risk mental states. Paranoia in virtual reality was understandable in terms of the cognitive model of persecutory delusions
