Embedding Logics into Product Logic

We construct a faithful interpretation of ukasiewicz's logic in product logic (both propositional and predicate). Using known facts it follows that the product predicate logic is not recursively axiomatizable.We prove a completeness theorem for product logic extended by a unary connective of Baaz [1]. We show that Gödel's logic is a sublogic of this extended product logic.We also prove NP-completeness of the set of propositional formulas satisfiable in product logic (resp. in Gödel's logic).     

Adaptation effects on evoked electrical taste

In spite of a clear increment in absolute thresholds as an effect of self-adaptation, the electrically provoked taste sensation does not show a reduction in subjective intensity during the protracted stimulation time. Chemical cross-adaptation effects on the threshold and suprathreshold levels of electrical taste are observed only when the adapting solutions are electrolytes regardless of their taste qualities. It seems that the stability of perceived intensity during current flow is principally due to some irritation of the sensitive tissue of the tongue, whereas cross-adaptation effects may be attributed to the potential changes across the excitable membranes caused by electrical properties of adapting electrolytic solutions.     

The influence of linguistic and cognitive factors on the time course of verb-based implicit causality

In three eye-tracking experiments the influence of the Dutch causal connective “want” (because) and the working memory capacity of readers on the usage of verb-based implicit causality was examined. Experiments 1 and 2 showed that although a causal connective is not required to activate implicit causality information during reading, effects of implicit causality surfaced more rapidly and were more pronounced when a connective was present in the discourse than when it was absent. In addition, Experiment 3 revealed that—in contrast to previous claims—the activation of implicit causality is not a resource-consuming mental operation. Moreover, readers with higher and lower working memory capacities behaved differently in a dual-task situation. Higher span readers were more likely to use implicit causality when they had all their working memory resources at their disposal. Lower span readers showed the opposite pattern as they were more likely to use the implicit causality cue in the case of an additional working memory load. The results emphasize that both linguistic and cognitive factors mediate the impact of implicit causality on text comprehension. The implications of these results are discussed in terms of the ongoing controversies in the literature—that is, the focusing-integration debate and the debates on the source of implicit causality.     

Validity of the Czech Version of the Therapeutic Factors Inventory – Short Form (TFI-S)

This study’s aim was to assess validity of the Czech translation of the Therapeutic Factors Inventory (TFI-S), which includes four factors: Instillation of Hope, Secure Emotional Expression, Awareness of Emotional Impact, and Social Learning. We assessed data from 220 patients who attended a daily three-month treatment program that used integrative group psychotherapy. TFI-S’s reliability was satisfactory: at week 12, Cronbach’s α was .93 and McDonald’s ω was .95. Confirmatory factor analysis showed acceptable fit to our data: at week 12, χ²(146) = 262.5, p < 0.001, CFI = .994, TLI = .992, RMSEA = .071 (90% CI = .057–.084), and SRMR = .063. Predictive validity showed significant correlations between TFI-S factors and pre/post-treatment change. In the conclusion, we discuss possible future potential of cross-cultural research.     

Brain activity underlying negative self- and other-perception in adolescents: The role of attachment-derived self-representations

One of teenagers’ key developmental tasks is to engage in new and meaningful relationships with peers and adults outside the family context. Attachment-derived expectations about the self and others in terms of internal attachment working models have the potential to shape such social reorientation processes critically and thereby influence adolescents’ social-emotional development and social integration. Because the neural underpinnings of this developmental task remain largely unknown, we sought to investigate them by functional magnetic resonance imaging. We asked n = 44 adolescents (ages 12.01–18.84 years) to evaluate positive and negative adjectives regarding either themselves or a close other during an adapted version of the well-established self-other trait-evaluation task. As measures of attachment, we obtained scores reflecting participants’ positive versus negative attachment-derived self- and other-models by means of the Relationship Questionnaire. We controlled for possible confounding factors by also obtaining scores reflecting internalizing/externalizing problems, schizotypy, and borderline symptomatology. Our results revealed that participants with a more negative attachment-derived self-model showed increased brain activity during positive and negative adjective evaluation regarding the self, but decreased brain activity during negative adjective evaluation regarding a close other, in bilateral amygdala/parahippocampus, bilateral anterior temporal pole/anterior superior temporal gyrus, and left dorsolateral prefrontal cortex. These findings suggest that a low positivity of the self-concept characteristic for the attachment anxiety dimension may influence neural information processing, but in opposite directions when it comes to self- versus (close) other-representations. We discuss our results in the framework of attachment theory and regarding their implications especially for adolescent social-emotional development and social integration.     

Incongruences of Ethical and Legal Norms in Academia: the Case on Revocation of Doctoral Degrees

In the academic setting as in any organization legal norms prevail and are assumed to be congruent with ethical norms. Nevertheless, there are cases when the ratio of ethical and legal norms is inadequate and disproportional, especially those dealing with socially responsible decisions in academia. For this reason, the aim here is to analyse incongruences of ethical and legal norms related to the revocation of doctoral degrees in Lithuania, illustrated with examples of deviant behaviour by academic degree holders in terms of decisions of the courts and the ombudsman for academic ethics. Lithuania, being a Member State of the European Union, is currently facing the challenge of implementing newly-adopted laws related to the revocation of doctoral degrees. Accordingly, data were collected from available online official sources to gain more comprehensive evidence, and then analysed using the inductive approach of qualitative content analysis. Research findings show that there is still a thin line between ethical and legal norms, and this line fluctuates depending on nuanced considerations. This is to say that it is still problematical to dress ethical principles in legal clothing.     

Are the aesthetic preferences towards snake species already formed in pre-school aged children?

This study explores aesthetic preferences towards boa and python species among pre-school children and adults, and compares the ratings between the two groups. A set of snake photographs was presented (56 species) to children and adult respondents. The respondents were asked to select the five most preferred and five least preferred species. The children’s agreement on which species were ‘beautiful’ and which were ‘ugly’ was statistically significant and a positive relationship between the mean ranks provided by children and adults was also found (r = .54, P < .001). Children preferred species with thick necks and inconspicuous heads, usually small species, harmless to children. Large pythons probably posed more danger to children than they did to adults during human evolution in African savannas and therefore we hypothesize that young children’s aesthetic preferences were shaped by natural selection through interactions with dangerous snakes.     

MATERNAL TRAUMA AFFECTS PRENATAL MENTAL HEALTH AND INFANT STRESS REGULATION AMONG PALESTINIAN DYADS

We examined how diverse and cumulated traumatic experiences predicted maternal prenatal mental health and infant stress regulation in war conditions and whether maternal mental health mediated the association between trauma and infant stress regulation. Participants were 511 Palestinian mothers from the Gaza Strip who reported exposure to current war trauma (WT), past childhood emotional (CEA) and physical abuse, socioeconomic status (SES), prenatal mental health problems (posttraumatic stress disorder and depression symptoms), and perceived stress during their secondtrimester of pregnancy as well as infant stress regulation at 4 months. While all trauma types were associated with high levels of prenatal symptoms, CEA had the most wide‐ranging effects and was uniquely associated with depression symptoms. Concerning infant stress regulation, mothers’ CEA predicted negative affectivity, but only among mothers with low WT. Against hypothesis, the effects of maternal trauma on infant stress regulation were not mediated by mental health symptoms. Mothers’ higher SES was associated with better infant stress regulation whereas infant prematurity and male sex predisposed for difficulties. Our findings suggest that maternal childhood abuse, especially CEA, should be a central treatment target among war‐exposed families. Cumulated psychosocial stressors might increase the risk for transgenerational problems.     

The Roles of Child Gender and Parental Knowledge of Child Development in Parent-Child Interactive Play

In our study, we aimed to analyse the effect of child gender on parental and child interactive play behaviour, as well as to determine relations between parental general knowledge of child development and parental play behaviour in two developmental periods, namely toddlerhood and early childhood. The sample included 99 children (50 toddlers 1–3 years-old; 49 preschoolers 3–5 years-old) and their parents. Parent–child interactive play with a standard set of toys was observed and assessed in the home setting. We found that parental and child play behaviours were closely related in both age groups. In addition, child’s gender affected child, but not parental, play behaviour such that girls more frequently established the content of play, sustained play frame, and used more symbolic transformations during play than boys did. Parents’ general knowledge of child development was associated with both parental education and parental play behaviour. The findings are applicable to different professionals working with children and their parents in the preschool period.
