Is an interest in computers or individual/team sports associated with adolescent psychiatric disorders?

The Internet plays a major role in adolescents' free time activities and communication nowadays. The aim here was to investigate the possibility of an association of computers and video games or sports (team, individual) with psychiatric disorders among underage psychiatric inpatients. The series of adolescents (n?=?508) had been diagnosed using semistructured interviews (K-SADS-PL). The results showed that an interest in computers and video games did not increase the risk of any specific psychiatric disorder among these adolescent inpatients, but the likelihood of a substance-related disorder was statistically significantly lower among the boys with computers as a hobby. Team sports were related to increased likelihood of conduct disorder among the boys, whereas the likelihood of an affective disorder was reduced. No such association was found in individual sports or among the girls. We conclude that social contacts and peers play an important role in preventing adolescent depression.     

Dogs do look at images: eye tracking in canine cognition research

Despite intense research on the visual communication of domestic dogs, their cognitive capacities have not yet been explored by eye tracking. The aim of the current study was to expand knowledge on the visual cognition of dogs using contact-free eye movement tracking under conditions where social cueing and associative learning were ruled out. We examined whether dogs spontaneously look at actual objects within pictures and can differentiate between pictures according to their novelty or categorical information content. Eye movements of six domestic dogs were tracked during presentation of digital color images of human faces, dog faces, toys, and alphabetic characters. We found that dogs focused their attention on the informative regions of the images without any task-specific pre-training and their gazing behavior depended on the image category. Dogs preferred the facial images of conspecifics over other categories and fixated on a familiar image longer than on novel stimuli regardless of the category. Dogs’ attraction to conspecifics over human faces and inanimate objects might reflect their natural interest, but further studies are needed to establish whether dogs possess picture object recognition. Contact-free eye movement tracking is a promising method for the broader exploration of processes underlying special socio-cognitive skills in dogs previously found in behavioral studies.     

Knowledge of Language Transfers From Speech to Sign: Evidence From Doubling

Does knowledge of language transfer across language modalities? For example, can speakers who have had no sign language experience spontaneously project grammatical principles of English to American Sign Language (ASL) signs? To address this question, here, we explore a grammatical illusion. Using spoken language, we first show that a single word with doubling (e.g., trafraf) can elicit conflicting linguistic responses, depending on the level of linguistic analysis (phonology vs. morphology). We next show that speakers with no command of a sign language extend these same principles to novel ASL signs. Remarkably, the morphological analysis of ASL signs depends on the morphology of participants' spoken language. Speakers of Malayalam (a language with rich reduplicative morphology) prefer XX signs when doubling signals morphological plurality, whereas no such preference is seen in speakers of Mandarin (a language with no productive plural morphology). Our conclusions open up the possibility that some linguistic principles are amodal and abstract.     

The threat simulation theory of the evolutionary function of dreaming: Evidence from dreams of traumatized children

The threat simulation theory of dreaming (TST) () states that dream consciousness is essentially an ancient biological defence mechanism, evolutionarily selected for its capacity to repeatedly simulate threatening events. Threat simulation during dreaming rehearses the cognitive mechanisms required for efficient threat perception and threat avoidance, leading to increased probability of reproductive success during human evolution. One hypothesis drawn from TST is that real threatening events encountered by the individual during wakefulness should lead to an increased activation of the system, a threat simulation response, and therefore, to an increased frequency and severity of threatening events in dreams. Consequently, children who live in an environment in which their physical and psychological well-being is constantly threatened should have a highly activated dream production and threat simulation system, whereas children living in a safe environment that is relatively free of such threat cues should have a weakly activated system. We tested this hypothesis by analysing the content of dream reports from severely traumatized and less traumatized Kurdish children and ordinary, non-traumatized Finnish children. Our results give support for most of the predictions drawn from TST. The severely traumatized children reported a significantly greater number of dreams and their dreams included a higher number of threatening dream events. The dream threats of traumatized children were also more severe in nature than the threats of less traumatized or non-traumatized children.     

Changes in studying abilities as perceived by students attending psychotherapy

In rehabilitative psychotherapy, the goal is to support and improve the person's working and studying capacity and to secure his/her staying in or entering the workforce. In this qualitative study, the aim was to describe the changes students experienced in their studying ability and the advancement of their studies as a result of the therapy process. The results of this study showed many kinds of positive changes in the psychological resources and studying ability of students participating in psychotherapy. The results also show that when psychotherapy is arranged with the aim to support the study process, good connections between psychotherapy, study tutoring and career guidance are needed.     

The Impact of Participating in Suicide Research Online

The impact of participation in online mixed‐methods suicide research was investigated. Participants, who described feeling suicidal, completed an 18‐item questionnaire before and after taking part (n = 103), and answered open‐ended questions about participation (n = 97). Overall, participation reduced negative experiences and had no effect on positive experiences. Feelings of calm increased, but participants felt less supported. Some participants did experience distress, but some also reported this distress to be manageable. Anonymously sharing experiences of suicidality was viewed as important, had therapeutic benefits, and engendered hopes for recovery. The findings suggest a need to ensure vulnerable participants in online studies are well supported while protecting their anonymity.
