A Model of Mental State Transition Network

Emotion is one of the most essential and basic attributes of human intelligence. Current AI (Artificial Intelligence) research is concentrating on physical components of emotion, rarely is it carried out from the view of psychology directly(1). Study on the model of artificial psychology is the first step in the development of human-computer interaction. As affective computing remains unpredictable, creating a reasonable mental model becomes the primary task for building a hybrid system. A pragmatic mental model is also the fundament of some key topics such as recognition and synthesis of emotions. In this paper a Mental State Transition Network Model(2) is proposed to detect human emotions. By a series of psychological experiments, we present a new way to predict coming human's emotions depending on the various current emotional states under various stimuli. Besides, people in different genders and characters are taken into consideration in our investigation. According to the psychological experiments data derived from 200 questionnaires, a Mental State Transition Network Model for describing the transitions in distribution among the emotions and relationships between internal mental situations and external are concluded. Further more the coefficients of the mental transition network model were achieved. Comparing seven relative evaluating experiments, an average precision rate of 0.843 is achieved using a set of samples for the proposed model.

Quality of life among people with epilepsy and mild intellectual disabilities in residential care

This study examined quality-of-life (QOL) evaluations among people with epilepsy and mild intellectual disabilities in residential care to determine their covariation and potential determinants. Participants were 111 clients of the Bethel Institute, Bielefeld, Germany. They completed questionnaires on their overall QOL and life satisfaction, the PESOS scales on epilepsy-related QOL, the Brief Symptom Inventory (BSI), and scales on activities of daily life and work-related problems in face-to-face-interviews. QOL evaluations differed in the various domains and tended to be better on more concrete items. Correlations of generic QOL parameters with scales on epilepsy-related QOL were only weak. BSI scores reflecting the current emotional state were identified as the most influential predictors of all QOL measures. The weak relationship between non-health-related parameters of subjective QOL and epilepsy-related QOL requires further investigation and theoretical explanation, whereas the influence of negative affect on different QOL dimensions is in line with previous QOL findings.

Early Life Stress and Morphometry of the Adult Anterior Cingulate Cortex and Caudate Nuclei

Early life stress (ELS) is linked to adult psychopathology and may contribute to long-term brain alterations, as suggested by studies of women who suffered childhood sexual abuse. We examine whether reported adverse ELS defined as stressful and/or traumatic adverse childhood events (ACEs) is associated with smaller limbic and basal ganglia volumes. 265 healthy Australian men and women without psychopathology or brain disorders were studied. ACEs were assessed by the ELSQ and current emotional state by the DASS. Anterior cingulate cortex (ACC), hippocampus, amygdala, and caudate nucleus volumes were measured from T1-weighted MRI. Analyses examined ROI volumetric associations with reported ACEs and DASS scores. Participants with greater than two ACEs had smaller ACC and caudate nuclei than those without ACEs. A significant association between total ACEs and ROI volumes for these structures was observed. Regression analysis also revealed that ELS was more strongly associated than current emotional state (DASS) with these ROI volumes. Reported ELS is associated with smaller ACC and caudate volumes, but not the hippocampal or amygdala volumes. The reasons for these brain effects are not entirely clear, but may reflect the influence of early stress and traumatic events on the developing brain.

Phonetics and social action in agreements and disagreements

This paper integrates sequential, interactional and phonetic analyses to provide an account of how ‘paralinguistic’ features create meaning. The analysis is based on assessment sequences from conversation, which were analysed using the methodology of Conversation Analysis in conjunction with phonetic analysis (cf. Couper-Kuhlen and Selting 1996; Couper-Kuhlen and Ford 2004, and papers therein). The analysis shows that there is a close relationship between the action conveyed in a turn and its phonetic format. Second assessment turns may be formatted lexically and syntactically as conveying agreement (such as isn’t that good news/ yes it's very good news), but given the right phonetic shape, they are treated as projecting disagreement. This highlights the significance of phonetics in participants’ construction of meaning. The phonetic resources used to convey agreement and disagreement are broadly speaking ‘paralinguistic’, because they are gradient rather than categorial, and do not relate straightforwardly to propositional content. While paralinguistic features are usually said to relate to “the speaker's current affective, attitudinal or emotional state” (Laver 1994:21), this analysis shows that linguistic forms are recurrently mapped on to the actions conveyed by turns at talk, and that the details of these forms are syntagmatically related to the design of prior turns.

Reduced specificity of autobiographical memories following a negative mood induction

Reduced autobiographical memory specificity (AMS) to emotional and neutral cue words appears to be a stable cognitive marker of clinical depression. For example, reduced AMS is present in remitted/recovered depressed patients and shows no reliable relationship with current levels of depressed mood in correlational studies. The present study examined whether reduced AMS could be induced in healthy volunteers with no history of depression, using a negative mood manipulation and whether levels of AMS and induced mood were positively correlated. Results showed a reduction in AMS following negative mood induction, compared to a neutral induction, whereas positive mood induction had no effects on AMS. Furthermore, lower happiness following the induction phase correlated positively with reduced AMS, and the extent of happiness reduction from pre- to post-induction correlated positively with reduction in AMS. These results suggest that AMS is, at least in part, a function of current emotion state. The implications for the literature on AMS as a stable marker of clinical depression are discussed.

Exploring the Influence of Vocal Emotion Expression on Communicative Effectiveness

This study explores whether speaker emotion influences communicative effectiveness. Two hundred participants rated their current emotional state and gave a description of a route on a simple map. The quality of the linguistic content of the descriptions was assessed using Latent Semantic Analysis. Six hundred participants provided route drawings based on the map descriptions. Median route deviation served as a measure of communicative effectiveness. Eighty addi-tional participants rated invariant parts of the descriptions for perceived speaker happiness. Path analysis revealed that while speaker emotion did not affect the linguistic content of the descriptions, it had an effect on communicative effective-ness both through the effects of vocal cues directly as well as mediated by per-ceived happiness of speech. Specifically, higher first formants were associated with higher reported and perceived happiness as well as higher communicative effectiveness. Jitter, on the other hand, was negatively related to the perception of happiness and positively related to communicative effectiveness. These findings suggest that mood-related modulation of phonation and articulation can influence the effectiveness of communication in addition to message content.

The Effect of Emotion and Personality on Olfactory Perception

It is well established that both the emotional tone of sensory stimuli and the personality characteristics of an individual can bias sensory perception. What has largely been unexplored is whether the current emotional state of an individual has a similar effect, and how it works together with other factors. Here we carry out a comprehensive study to examine how olfactory perception is affected by the emotional tone of the stimuli, and the personality and current emotional state of the individual. Subjects reported experiencing happiness, sadness, negativity/hostility and neutrality when exposed to corresponding emotionally themed video clips, and in each case, smelled a suprathreshold pleasant, an unpleasant and a neutral odorant. The time taken for the subject to detect each odorant and the olfactory intensity were recorded. We found that women detected the pleasant odorant faster than the neutral one. In addition, personality modulated reaction time and olfactory intensity, such that neurotic and anxious individuals were selectively biased toward affective rather than neutral odorants. Finally, current emotional state augmented intensity in men but not in women, and differentially influenced the response time. These findings provided new insights into the effects of emotion and personality on olfactory perception.

Perceptions of control over heart disease in people with an inherited predisposition to raised cholesterol

This cross-sectional study aimed to describe the perception of control over heart disease, and the likely antecedents of this perception, in 340 people with an inherited predisposition to premature coronary heart disease. Dependent variables were self-efficacy and response efficacy. Independent variables were history of heart disease and current symptoms, current cholesterol level, emotional state, and causal attributions. Overall, levels of perceived personal control (self-efficacy) were moderately high and treatment was perceived to be effective (response efficacy). Predictors were having a lower current cholesterol level, not experiencing symptoms of angina, lower anxiety, lower depression, and perceiving chance as less important and cholesterol as more important in causing a potential heart attack. Thus, previous and current experience together with causal attributions and emotional state are related to perceptions of control over heart disease in at-risk patients. These findings highlight the need to know more about the antecedents of perceiving control over disease.

Meselson and Stahl: The art of DNA replication

Emotions coordinate our behavior and physiological states during survival-salient events and pleasurable interactions. Even though we are often consciously aware of our current emotional state, such as anger or happiness, the mechanisms giving ...Emotions are often felt in the body, and somatosensory feedback has been proposed to trigger conscious emotional experiences. Here we reveal maps of bodily sensations associated with different emotions using a unique topographical self-report method. In ...

Is the Evaluation of the Global Quality of Life Determined by Emotional Status?

The present study investigated relationships between global QOL perceptions and well-being dimensions. Especially our goal was to evaluate the impact of generally recognised four broad dimensions of QOL (physical, functional, social and emotional well-being) on global QOL perceptions, additionally person's satisfaction with life achievements and economical situation were measured as well as social demographic variables. The subjects were a representative sample of Finns (n = 4613, from 25 to 65 years) of the FINRISK-97 study. Correlation coefficients and models of hierarchical regression indicated that physical, functional and social well-being as well as sociodemographic factors and satisfaction with life achievements are important factors of global QOL perceptions both among males and females. However percentages of variances explained with these measures were only moderately high, ranging from 1 to 10%. After measures of emotional well-being were entered into the models of hierarchical analyses of regression, variances explained grew dramatically over 20%. The results of the study indicated that global QOL judgements are likely to be based on current emotional state.

The detection of psychological problems by General Practitioners--influence of ethnicity and other demographic variables.

Common mental illness in Black Africans and Black Caribbeans has been relatively little studied in the UK. Previous studies of the detection of psychological problems by General Practitioners (GPs) in these groups have been inconclusive. The aim of this study was to investigate the prevalence, detection and management of psychological problems in General Practice among Black Caribbeans and Black Africans compared to White English attenders and to examine the relative contribution of other sociodemographic factors to these main outcome variables. Consecutive attenders aged 16-65 years at 18 General Practitioners in South-East London completed the General Health Questionnaire (GHQ-12) before seeing the GP. The GPs rated the current emotional state of the patients at the end of each consultation. Comparison of the GHQ and GP ratings was used to compute the detection indices. A total of 1211 patients aged 16-65 years were approached to take part in the study. Of the patients, 75 (6%) declined or were not able to complete the GHQ. In all, 994 individuals had both GP and GHQ ratings. There was an overall probable prevalence of 37%, of which 73% were identified as cases by the GPs. Black African patients had lower rates of common mental disorders, were less likely to be detected as psychiatric cases by the GP and less likely to receive active management for their psychological problems than Black Caribbean and White English patients. Rates of prevalence, detection and management were similar between Black Caribbean and White English patients. In the multivariate analysis, ethnicity, employment and age all played a significant independent role in predicting probable prevalence. The patients' reported decision to talk to their GP about psychological problems was the main predictor of detection. Ethnicity did not independently predict detection, but Black African cases were less likely to say that they would talk to their GP about psychological problems. GPs' identification indices mirrored probable prevalence, suggesting that GPs were more sensitive to detecting psychiatric illness in individuals belonging to groups which commonly presented as symptomatic. The findings suggest that in General Practice the prevalence of common mental disorders, their detection and management in Black Caribbeans are similar to those in White English, but that Black Africans have lower prevalence, are less likely to be detected and are less likely to receive active management. The study of GP consulters presents problems for the interpretation of these results and it may be that Black Africans with psychological problems are less likely than their Caribbean and English counterparts to attend their GP, and less willing to speak to them about these problems when they do. Future similar studies should distinguish Black African and Black Caribbean subjects in their analyses, as categories such as 'Afro-Caribbean' may mask important differences in attitudes and illness behaviour.

Cognitive, emotional and psychosocial factors in fragrance experience

Although the intensity and quality of fragrance perception is elicited by the physical mixture of volatile chemicals available to stimulate the olfactory system, the subjective experience and response an individual exhibits is often the product of those sensory or physiological signals and higher level psychological processes involved in perception, memory and judgment. For example, the frequency and duration of exposure to a fragrance can determine whether the subsequent perception is diminished (adaptation) or enhanced (sensitization), but an individual's memories of prior associations, the situational context or expectations, and their current emotional state are potent modifiers of the intensity and quality of the final chemosensory experience. Similarly, the context in which an irritant sensation is experienced (e.g., the product or situation) may determine whether it is perceived as an adverse or pleasurable sensation. Results from numerous laboratory studies have shown that these factors play a key role in the evaluation of odor and irritant sensations arising from the perception of fragrances. Importantly, cognitive and psychosocial factors appear to have significance for understanding reactions to fragrances in a variety of use situations, from consumer products to indoor environments.

The Role of Motivation in the Age-Related Positivity Effect in Autobiographical Memory

This study reveals that older adults have a positivity effect in long-term autobiographical memory and that a positivity bias can be induced in younger adults by a heightened motivation to regulate current emotional well-being. Three hundred nuns, ages 47 to 102 years, recalled personal information originally reported 14 years earlier. They did so under experimental conditions that repeatedly primed them to focus on their current emotional states or on their memory accuracy, or that provided no instructional focus (control condition). Both older control participants and participants who were focused on emotional states showed a tendency to remember the past more positively than they originally reported in 1987. In contrast, both younger control participants and participants who were focused on accuracy tended to remember the past more negatively than originally reported.

Reconsidering the Evolution of Nonlinguistic Communication: The Case of Laughter

Nonlinguistic communication is typically proposed to convey representational messages, implying that particular signals are associated with specific signaler emotions, intentions, or external referents. However, common signals produced by both nonhuman primates and humans may not exhibit such specificity, with human laughter for example showing significant diversity in both acoustic form and production context. We therefore outline an alternative to the representational approach, arguing that laughter and other nonlinguistic vocalizations are used to influence the affective states of listeners, thereby also affecting their behavior. In the case of laughter, we propose a primary function of accentuating or inducing positive affect in the perceiver in order to promote a more favorable stance toward the laugher. Two simple strategies are identified, namely producing laughter with acoustic features that have an immediate impact on listener arousal, and pairing these sounds with positive affect in the listener to create learned affective responses. Both depend on factors like the listener's current emotional state and past interactions with the vocalizer, with laughers predicted to adjust their sounds accordingly. This approach is used to explain findings from two experimental studies that examined the use of laughter in same-sex and different-sex dyads composed of either friends or strangers, and may be applicable to other forms of nonlinguistic communication.

Forgetting, fabricating, and telescoping: the instability of the medical history.

Patients' recollections of their past symptoms, illnesses, and episodes of care are often inconsistent from one inquiry to the next. Patients frequently fail to recall (and therefore underreport) the incidence of previous symptoms and events; tend to combine separate, similar occurrences into a single, generic memory; and falsely recall medical events and symptoms that did not in fact occur. This unreliability of recall is affected by personality characteristics and by the patient's current state at the time of recall. Thus, current anxiety or depression and pain or bodily distress foster the recall of symptoms and events that are not recalled when the patient is more comfortable. Finally, current beliefs about one's health and the nature and causes of one's illness also affect the recall of past symptoms and illness. Physicians can maximize the reliability of the clinical history by (1) noting and taking into account the patient's current physical and emotional state; (2) first establishing historical "anchor points" or memorable milestones; (3) decomposing generic memories by finding features that distinguish them from each other; and (4) recalling the clinical history in retrograde fashion, beginning with the most recent event and working backward.

Mood, eating behaviour and attention.

Obesity is a growing health problem, but most people find dieting unsuccessful. Three studies examine possible reasons for the difficulty and the extent to which dieting-related reductions in cognitive function are associated with mood and well-being. In Study One, 49 female dieters were compared with a control group of 31 matched non-dieters on measures of well-being, mood, eating behaviour (Dutch Eating Behaviour Questionnaire), and attention. Study Two examined two measures of restraint to examine why previous studies find high restrainers are prone to react to emotion. Study Three experimentally manipulated mood using music and the standard Velten Induction Procedure to examine attention in restrainers and emotional eaters. Dieting was found to be associated with deficits in sustained attention. This finding was further supported by the demonstration of a significant impairment in performance following a negative mood induction in high emotional eaters whereas high restrainers were relatively unaffected by the mood challenge. We suggest that different aspects of eating behaviour have dissociable effects on cognitive-affective function. Trait tendencies to restrained eating are associated with attentional deficits, but are not further affected by mood disruption. It is the long-term tendency to eat when emotional that combines with current emotional state to trigger cognitive deficits.

High prevalence of anxiety symptoms in hospitalized geriatric patients.

To examine the prevalence of anxiety symptoms in hospitalized geriatric patients. Controlled cross-sectional study. Ninety-eight geriatric in-patients and 68 healthy home-dwelling controls of similar age recruited from senior citizen centres. Anxiety measured as a current emotional state by Spielberger's State-Trait Anxiety Inventory (STAI). The geriatric patients scored significantly higher than the controls. Applying Spielberger's recommended cut-off of 39/40 on the STAI sumscore, 41% of the female and 47% of the male geriatric patients might be suspected of suffering from significant anxiety symptoms. Patients with chronic obstructive pulmonary disease tended to score higher; otherwise no relationship was found between the STAI sumscore and type of chronic somatic disease, nor between the STAI sumscore and number of drugs in regular use. STAI proved feasible for use in the elderly. The scoring on the STAI is high in geriatric in-patients. Further studies are needed to clarify to what extent this relates to a high prevalence of anxiety disorders.

The Effect of Affect on Economic and Strategic Decision Making

The standard economic model of decision making assumes a decision maker makes her choices to maximize her utility or happiness. Her current emotional state is not explicitly considered. Yet there is a large psychological literature that shows that current emotional state, in particular positive affect, has a significant effect on decision making. This paper offers a way to incorporate this insight from psychology into economic modeling. Moreover, this paper shows that this simple insight can parsimoniously explain a wide variety of behaviors.

Metacognition and clinical psychology: a preliminary framework for research and practice

A theoretical framework for metacognition in clinical psychology is proposed that emphasizes the metacognitive monitoring and metacognitive control of emotional states. The proposal is that the person monitors his/her emotional state, applies a label to it, compares it to a goal state, and takes action to make the current emotional state become closer to the goal state. Implications are drawn for clinical research and clinical practice, with examples given for schizophrenia and excessive anger. Copyright © 1999 John Wiley & Sons, Ltd.
