Integrating a cognitive computational model of planning and decision-making considering affective information

Planning and decision-making are two of the cognitive functions involved in the solution of problems. These functions, among others, have been studied from the point of view of a new field known as cognitive informatics focused on the development of cognitive architectures, autonomous agents, and human robots that are capable of showing human-like behavior. We present an exhaustive study of current biological and computational models proposed in the fields of neuroscience, psychology, and cognitive informatics. Also, we present a deep review of the brain areas involved in planning, decision-making, and affection. However, the majority of the proposed computational models are seeking to mimic human external behavior. This paper aims to contribute to the cognitive informatics field with an innovative cognitive computational model of planning and decision-making. The two main differences of our model with respect to the current models in the literature are: (i) our model considers affective and motivational information as a basic and essential trigger in planning and decision-making processes; (ii) our model attempts to mimic both the internal human brain as well as the external human behavior. We developed a computational model capable of offering a direct mapping from human brain areas to computational modules of our model. Thus, in this paper we present our model from a conceptual, formal, and computational approach in order to show how our proposal must be implemented. Finally, a set of tests were conducted in order to validate our proposal. These tests show an interesting comparison between the behavior of our prototype and the behavior exhibited by some people involved in a case study.     

Forgiveness as a mediator of the relationship between PTSD and hostility in survivors of childhood abuse

This paper argues that emotional inferences about characters in a text are not as specific as previously assumed (DeVega, Diaz, & Leon, 1997; DeVega, Leon, & Diaz 1996; Gernsbacher, Goldsmith, & Robertson, 1992; Gernsbacher, Hollada, & Robertson, 1998; Gernsbacher & Robertson, 1992). The emotional information inferred by readers does not differentiate between emotions that are similar, though not identical. In both Experiments 1 and 2, participants read the stories used by Gernsbacher et al. (1992). Results from Experiment 1 (off-line) show that participants judged several emotions consistent with the same story. In Experiment 2 (on-line), participants took longer to read target sentences containing emotions mismatching the stories, but there was no difference between target sentences containing different matching emotions as determined by Experiment 1. Results from Experiments 1 and 2 suggest that the emotional information readers infer from the stories is too broad to determine a specific emotion. The results are consistent with the idea that a general emotional response is evoked, which is compatible with one or more specific emotions.     

Standing out as a signal to selfishness: Culture and devaluation of non-normative characteristics

This article proposes and tests a theoretical model articulating when and why differences in devaluation and avoidance of individuals with non-normative characteristics emerge between East Asian and Western cultural contexts. Four main studies examined this theoretical model. In a pilot study, relative to Americans, Koreans devalued a target individual with a non-normative characteristic, and in Study 1 the target’s efforts to forestall disruption of group processes eliminated the devaluation in Korea, with perceived selfishness mediating this process. In Study 2, Koreans, relative to Americans, devalued and avoided coworkers with non-normative characteristics, particularly when the non-normative characteristic was controllable. Study 3 further showed that perceived selfishness mediates this effect with a behavioral dependent variable. Study 4 tested the generalizability to positively valenced characteristics and found that Koreans (relative to Americans) also devalue individuals with positive characteristics at non-normative levels. Implications for individuals with non-normative characteristics, organizational diversity, and cross-cultural interaction are discussed.     

Terrorism as a process: a critical review of Moghaddam's "Staircase to Terrorism"

This study reviews empirical evidence for Moghaddam's model "Staircase to Terrorism," which portrays terrorism as a process of six consecutive steps culminating in terrorism. An extensive literature search, where 2,564 publications on terrorism were screened, resulted in 38 articles which were subject to further analysis. The results showed that while most of the theories and processes linked to Moghaddam's model are supported by empirical evidence, the proposed transitions between the different steps are not. These results may question the validity of a linear stepwise model and may suggest that a combination of mechanisms/factors could combine in different ways to produce terrorism.     

Therapists' Emotional Reactions to Patients as a Mediator in Cognitive Behavioural Treatment of Panic Disorder with Agoraphobia

The aims of this study were to examine whether therapists' emotional reactions to their patients mediate the effect of personality disorders and interpersonal problem behaviours on the outcome of treatment, focusing on an Axis I disorder; and whether therapists' reactions mediate the effect of personality disorders on the course of interpersonal problems. Therapists completed a checklist of emotional reactions to individual patients after the end of residential cognitive or guided mastery therapy for 46 inpatients with panic disorder with agoraphobia. The severity of DSM‐III‐R personality disorder was related to therapists' insecurity feelings, but not to interest and anger. A higher level of therapists' insecurity feelings was related to less reduction in self‐reported agoraphobic avoidance during treatment, whereas therapists' emotions were unrelated to symptomatic course after treatment. Therapists' insecurity feelings appeared partly to mediate the relationship between patients' severity of personality disorder and persistence of patients' interpersonal dominance and nurturance problems.     

Coping as a building mechanism to explain the unique association of affect and goal motivation with changes in affective states

Background and objectives: In this study, we examined the mediating role of university students’ coping strategies in the unique/additive influence of affective states and goal motivation on upward changes in affect during a midterm exam period. Design: Using a short-term prospective design, key assumptions from the self-concordance model and the broaden-and-build theory were drawn upon to determine whether coping strategies are influenced by goal motivation and affective states, while also subsequently influencing short-term changes in affective states during a semester. Method: A sample of 272 students (79% females and 21% males) participated in a study in which they completed questionnaires twice during the semester. Results: Results of structural equation modeling, using a true latent change approach, have generally supported our hypotheses. Positive affective states and autonomous goal motivation prospectively predicted task-oriented coping which, in turn, was associated with increases in positive affect. Negative affective states and controlled goal motivation prospectively predicted disengagement-oriented coping which, in turn, was associated with increases in negative affect. Conclusion: Coping partially mediates the unique association of affect and goal motivation with changes in affective states of university students.
