Paraconsistent and Paracomplete Logics Based on k-Cyclic Modal Pseudocomplemented De Morgan Algebras

Studia Logica - The study of the theory of operators over modal pseudocomplemented De Morgan algebras was begun in papers [20] and [21]. In this paper, we introduce and study the class of modal...     

What is so frightening about spiders? Self‐rated and self‐disclosed impact of different characteristics and associations with phobia symptoms

Spider phobia is a common and impairing mental disorder, yet little is known about what characteristics of spiders that spider phobic individuals find frightening. Using screening data from a clinical trial, we explored which characteristics that spider‐fearful individuals (n = 194) rated as having the greatest impact on fear, used factor analysis to group specific characteristics, and explored linear associations with self‐reported phobia symptoms. Second, a guided text‐mining approach was used to extract the most common words in free‐text responses to the question: “What is it about spiders that you find frightening?” Both analysis types suggested that movement‐related characteristics of spiders were the most important, followed by appearance characteristics. There were, however, no linear associations with degree of phobia symptoms. Our findings reveal the importance of targeting movement‐related fears in in‐vivo exposure therapy for spider phobia and using realistically animated spider stimuli in computer‐based experimental paradigms and clinical interventions such as Virtual Reality exposure therapy.     

Confirmatory factor analysis of the behavior rating inventory of executive function in a neuro-pediatric sample and its application to mental disorders

The construct validity of the 9-scale version of the Behavior Rating Inventory of Executive Function (BRIEF) parent form was examined in a clinical sample of children and adolescents with neurological and neurodevelopmental disorders (N = 281). Confirmatory factor analysis supported a three-factor model separating the inhibitory behavioral control dimension from the emotional control and metacognitive problem-solving dimensions. The Metacognitive factor was also related to a diagnosis of attention deficit/hyperactivity disorder (ADHD) after controlling for age, gender, IQ, adaptive functioning, and a conventional behavioral rating scale, which included inattention-hyperactivity symptoms. The Emotional Regulation factor was related to a diagnosis of oppositional defiant disorder. Correlational analyses indicated that child comorbid emotional and behavioral problems may exacerbate parental BRIEF reporting. Accordingly, when assessing executive function among children with neurological and neurodevelopmental disorders, the BRIEF should be complemented with assessments of mental health problems.     

Domestication effects on social information transfer in chickens

Animal Cognition - Red junglefowl (RJF), ancestor of all domesticated chickens, is a highly social, omnivorous bird species, presumably with a capacity for social information sharing. During...     

Suppression-induced forgetting diminishes following a delay of either sleep or wake

ABSTRACT

We investigated the duration of suppression-induced forgetting (SIF), and the extent to which retrieval suppression differs between negative and neutral memories. We further examined if SIF was differently affected by sleep versus wake during the delay interval between retrieval suppression and re-test. Fifty participants first learned to associate neutral words with either neutral or negative images. Then, a subset of the words was shown again, and participants were asked to either recall (Think), or to suppress retrieval of (No-Think) the associated images. Finally, a memory test for all items was performed either immediately after the Think/No-Think (T/NT) phase (No Delay), or after a 3.5?h delay interval containing either sleep or wake. Results revealed a SIF effect only in the No Delay group, indicating that this forgetting effect dissipates already after a 3.5?h delay interval. Negative items were experienced as more intrusive than neutral ones during the T/NT phase.
