Irrational and Metacognitive Beliefs Mediate the Relationship Between Content Beliefs and GAD Symptoms: A Study on a Normal Population

Cognitive Behavioral Therapy (CBT), Rational Emotive Behavior Therapy (REBT) and Metacognitive Therapy (MCT) models show both similarities and differences in conceptualizing anxiety. This work assumes that REBT’s irrational and MCT’s metacognitive beliefs play a mediation role while CBT’s disorder specific content beliefs act as triggers. This hypothesis is tested using a regression model in which metacognitive and irrational beliefs play a mediation role while content disorder beliefs are independent variables. This paper applied this model to generalized anxiety disorder (GAD), a psychiatric diagnosis in which anxiety is the major feature. In GAD, the specific content beliefs are negative problem orientation and intolerance of uncertainty. Therefore, 149 non clinical subjects completed 4 self-report questionnaires: the Negative Orientation to the Problems Questionnaire and the Intolerance of Uncertainty Scale as measures for content cognitive beliefs, the Attitudes and Beliefs Scale for irrational beliefs, and the Metacognitive Questionnaire 30 Items Version for metacognitive beliefs. The generalized anxiety disorder questionnaire was chosen in order to measure anxiety as dependent variable. Regression analyses confirmed that irrational and metacognitive beliefs mediate the relation between cognitive content beliefs and GAD. We clinically interpret mediation as a second level regulation.     

Parents of Adolescents with Mental Disorders: Improving Their Caregiving Experience

Several studies have demonstrated that the family members of adolescents with mental diseases experience distress, anxiety and depression, as well as economic strain, all of which contribute to physical and psychological caregiver morbidity. The aim of this study was to assess the effectiveness of intervention to improve the caregiving experience of the parents of mentally ill adolescents. The parents of 20 patients were assessed with the Experience of Caregiving Inventory (ECI) and the Working Alliance Inventory (WAI), while patients’ functioning and psychopathology were evaluated with the Global Assessment of Functioning (GAF) scale and the Child Behavior Check List (CBCL), respectively. Assessments were conducted over 9 months, comparing the experimental group receiving the intervention with a control group that received “standard” care. While there were no significant differences in the patients’ psychopathologies, the caregivers in the experimental group had better ECI and WAI scores. Intervention focusing on the parents seemed to improve the caregivers’ understanding of the disease’s impact on their lives irrespective of the severity of their children’s condition. This finding may be useful in developing adequate measures for the parents of adolescents with severe mental diseases to help contain their psychological distress.     

Computational explorations of perceptual symbol systems theory

The aim of this paper is twofold. First, we provide a methodological pathway from theories of situated, embodied cognition to simulations with an eye to empirical evidence, and suggest a possible cross-fertilization between cognitive robotics and psychology. Psychological theories, in particular those formulated at an abstract level, include models which are often severely underspecified at the level of mechanisms. This is true in the synchronic, constructive perspective (how can the effects observed in experiments be concretely generated by the model's mechanisms?) and in the diachronic, developmental perspective (how can such mechanisms be learned and developed?). The synthetic method of artificial cognitive systems research, and in particular of cognitive robotics, can complement research in psychology (and neurosciences) by exploring the constructive and developmental aspects of theories. Our second aim is to provide an example of such a methodology by describing simulations aiming at developing a perceptual symbol system (PSS) (Barsalou, 1999). We then describe the two main theoretical constructs of the PSS, perceptual symbols and simulators, illustrate their development in an artificial system, and test the system in prediction, categorization, and abstraction tasks.     

Workaholism and work engagement: how are they similar? How are they different? A systematic review and meta-analysis

Workaholism and work engagement can be depicted, respectively, as the pathological and the healthy form of heavy work investment. In spite of their different definitions and outcomes on individual and organizational life, workaholism and work engagement are not clearly and adequately distinguished by scholars and researchers as they appear to show some overlapping features. The aim of this investigation was to meta-analyze available studies, selected by systematic review, on the relations between subdimensions of workaholism and work engagement. Thirty-five studies were eligible for analysis. Associations emerged between Working Excessively and Absorption (g = .34), Working Compulsively and Absorption (g = .28), and Working Excessively and Dedication (g = .14). Moreover, the results were not influenced by publication bias and showed nationality to be a significant moderator. Overall, these findings suggest that further research is necessary to extend our knowledge of workaholism, work engagement, and the relationship between the two, in order to disentangle commonalities and differences between them.     

On Properties and Processes on Numerical Assignment: An Empiricist Approach

By starting from the idea of processes of numerical assignment, an explication, á la Kant, of the concept of property is proposed. In this way two results are achieved: on the one hand, the Kantian doctrine of explication is revaluated; on the other hand, the notion of property is tackled from an empiricist point of view based on the representational theory of measurement. This revised version was published online in August 2006 with corrections to the Cover Date.     

Motor functions of the Broca's region

Broca's region in the dominant cerebral hemisphere is known to mediate the production of language but also contributes to comprehension. This region evolved only in humans and is constituted of Brodmann's areas 44 and 45 in the inferior frontal gyrus. There is, however, evidence that Broca's region overlaps, at least in part, with the ventral premotor cortex. We summarize the evidence that the motor related part of Broca's area is localized in the opercular portion of the inferior frontal cortex, mainly in area 44 of Brodmann. According to our own data, there seems to be a homology between Brodmann area 44 in humans and the monkey area F5. The non-language related motor functions of Broca's region comprise complex hand movements, associative sensorimotor learning and sensorimotor integration. Brodmann's area 44 is also a part of a specialized parieto-premotor network and interacts significantly with the neighboring premotor areas.     

The mirror neuron system and action recognition

Mirror neurons, first described in the rostral part of monkey ventral premotor cortex (area F5), discharge both when the animal performs a goal-directed hand action and when it observes another individual performing the same or a similar action. More recently, in the same area mirror neurons responding to the observation of mouth actions have been also found. In humans, through an fMRI study, it has been shown that the observation of actions performed with the hand, the mouth and the foot leads to the activation of different sectors of Broca's area and premotor cortex, according to the effector involved in the observed action, following a somatotopic pattern which resembles the classical motor cortex homunculus. These results strongly support the existence of an execution-observation matching system (mirror neuron system). It has been proposed that this system is involved in action recognition. Experimental evidence in favor of this hypothesis both in the monkey and humans are shortly reviewed.
