Functional headaches in patients of a pediatric and adolescent neuropsychiatric counseling facility

After the evaluation of the anamnestic, clinical, and paraclinical data of 100 children and young persons with functional headache, the conclusion is reached: It is not considered cogently necessary; on clinical, paraclinical, therapeutic, and prognostic grounds, to differentiate between tense headache and migraine (complicated migraine forms excepted) in functional headache in children. A prevalence of girls below the age of 12, as described in literature, was not confirmed. Only from the age of 12 is there an increase in proportion of girls as first sufferers of functional headache. Short-term prognosis suggests effective non-medicamentive treatment.

Access,phenomenology and sorites

The non‐transitivity of the relation looks the same as has been used to argue that the relation has the same phenomenal character as is non‐transitive—a result that jeopardizes certain theories of consciousness. In this paper, I argue against this conclusion while granting the premise by dissociating lookings and phenomenology; an idea that some might find counter‐intuitive. However, such an intuition is left unsupported once phenomenology and cognitive access are distinguished from each other; a distinction that is conceptually and empirically grounded.     

What predicts anti‐Roma prejudice? Qualitative and quantitative analysis of everyday sentiments about the Roma

The present research focused on two primary goals: (a) identifying the content of sentiments about the Roma to which Hungarians are exposed during everyday family conversations, and (b) determining which types of everyday sentiments about the Roma most strongly predict Hungarian respondents’ anti‐Roma prejudice. Content analyzing open‐ended responses from a representative sample of Hungarians (N = 505), we found that more than 76% of the respondents reported being exposed to negative stereotypes about the Roma, 27% to threats posed by Roma, and 16% to overt dehumanization of Roma; additionally more than 20% reported hearing no positive sentiments about the Roma in everyday family conversations. We then examined which negative and positive sentiments most strongly predicted respondents’ anti‐Roma prejudice (using measures of social distance and modern racism). Higher social distance scores were predicted by a lack of positive sentiments, whereas lower social distance scores were most strongly predicted by unambiguously positive sentiments expressed during family conversations. Higher modern racism scores were further predicted by sentiments expressing dehumanization, threat, and violence against Roma. Together, these results attest to the extremity of anti‐Roma sentiments expressed regularly by Hungarians, and suggest how exposure to specific sentiments may foster anti‐Roma hostility. Moreover, these findings provide guidance regarding the specific negative anti‐Roma sentiments that should be combated to enhance the effectiveness of anti‐prejudice interventions.     

Direct Perceptual Access to Other Minds

It is sometimes claimed that we perceive people’s mental states in their expressive features. This paper clarifies the claim by contrasting two possible readings, depending on whether expression is conceived relationally or non-relationally. A crucial difference between both readings is that only a non-relational conception of expression ensures direct access to other minds. The paper offers an argument for a non-relational conception of expression, and therefore for the view that we directly perceive people’s mental states in their expressive features.     

Acute Aerobic Exercise Enhances Students’ Creativity

The purpose of this study was to evaluate the effectiveness of an aerobics games class on creativity in children during the school day. Participants were 96 students (age = 9.84 ± 1.12 years), 48 girls and 48 boys. The students were randomly assigned to the experimental group (EG, n = 48) or the control group (CG, n = 48). The Prueba de Imaginación Creativa-Niños (PIC-N) test was employed to assess narrative and graphic creativity. The EG took part in an aerobic games session lasting 45 min; the CG did not take part in a physical education class on that school day. As for group × time interaction, the EG experienced significant improvements in all creativity variables except in graphic originality, graphic titles, and graphic details. The CG did not improve any creativity variables. The findings suggest that acute aerobic exercise can enhance students’ creativity, which could be important for academic achievement.     

Poststimulation time interval-dependent effects of motor cortex anodal tDCS on reaction-time task performance

Anodal transcranial direct current stimulation (tDCS) induces long-term potentiation-like plasticity, which is associated with long-lasting effects on different cognitive, emotional, and motor performances. Specifically, tDCS applied over the motor cortex is considered to improve reaction time in simple and complex tasks. The timing of tDCS relative to task performance could determine the efficacy of tDCS to modulate performance. The aim of this study was to compare the effects of a single session of anodal tDCS (1.5 mA, for 15 min) applied over the left primary motor cortex (M1) versus sham stimulation on performance of a go/no-go simple reaction-time task carried out at three different time points after tDCS—namely, 0, 30, or 60 min after stimulation. Performance zero min after anodal tDCS was improved during the whole course of the task. Performance 30 min after anodal tDCS was improved only in the last block of the reaction-time task. Performance 60 min after anodal tDCS was not significantly different throughout the entire task. These findings suggest that the motor cortex excitability changes induced by tDCS can improve motor responses, and these effects critically depend on the time interval between stimulation and task performance.     

Weighing the past and the future in decision making

Prior irreversible investments of money, time, or effort referred to as sunk costs frequently lead to decisions to continue a chosen course of action despite that this is irrational. With the aim of demonstrating that such escalation of commitment is a special case of a more general phenomenon, two experiments were carried out employing undergraduates as participants. Experiment 1 showed for fictitious personal and business investment scenarios that both prior losses and gains (sunk outcomes) affected choices to continue or discontinue the investment. In Experiment 2 the effect of sunk outcomes was reduced although not eliminated by a monetary bonus that in one condition depended on the future outcomes of the second gamble in two-stage gambles, in another condition on the future returns in personal investment scenarios. In support of a more inclusive theory subsuming escalation of commitment, the decisions were affected by both past and future outcomes and both gains and losses.     

Timed picture naming in seven languages

Timed picture naming was compared in seven languages that vary along dimensions known to affect lexical access. Analyses over items focused on factors that determine cross-language universals and cross-language disparities. With regard to universals, number of alternative names had large effects on reaction time within and across languages after target-name agreement was controlled, suggesting inhibitory effects from lexical competitors. For all the languages, word frequency and goodness of depiction had large effects, but objective picture complexity did not. Effects of word structure variables (length, syllable structure, compounding, and initial frication) varied markedly over languages. Strong cross-language correlations were found in naming latencies, frequency, and length. Other-language frequency effects were observed (e.g., Chinese frequencies predicting Spanish reaction times) even after within-language effects were controlled (e.g., Spanish frequencies predicting Spanish reaction times). These surprising cross-language correlations challenge widely held assumptions about the lexical locus of length and frequency effects, suggesting instead that they may (at least in part) reflect familiarity and accessibility at a conceptual level that is shared over languages.
