Girls’ Stuff,boys’ stuff and mental rotation: fourth graders rotate faster with gender-congruent stimuli

Males outperform females in mental-rotation for various reasons, e.g. stimuli characteristics. This study tested the hypothesis that girls and boys solve mental-rotation tests with female- or respectively male-stereotyped objects faster and more correctly. 116 fourth-graders solved a chronometric mental-rotation test with either female- or male-stereotyped action-based objects as stimulus material and reported their solution strategies and familiarity with handling the objects in real life. Boys reacted faster than girls only in the male-stimuli condition, while gender differences were inversed in the female-stimuli condition. All children were faster with gender-congruent material, probably provoked by gender-schematic processing or stereotype lift effects. Furthermore, analytic solving strategies appeared as efficient as holistic strategies in gender-congruent conditions, while holistic strategies were more advantageous only in gender-incongruent conditions. The congruence of stimulus material and gender best predicted children’s reaction time. Practical implications are considered regarding the importance of diverse and gender-equalised material to assess mental-rotation skills.     

Psycholinguistic evidence for the underspecification of morphosyntactic features

This paper investigates the paradigmatic relations between inflected word forms (or their affixes) and the feature specifications of these elements. In two sentence-matching experiments German speakers had to decide whether sentence pairs involving inflected adjectives or determiners were identical or not. In both experiments, there was a delay when an inflected form contained positive feature specifications for grammatical features that did not match the feature specifications of the grammatical context in which it appeared. No delay, however, occurred when an incorrectly inflected form had mismatching negative specifications, whereas its positively specified features matched the respective positive features of the context. This result provides evidence for a different status of positively and negatively specified morphosyntactic features. It supports the idea of radical underspecification according to which only positive feature specifications are part of the representations of morphologically complex forms or affixes, whereas negative feature specifications are assigned on the basis of paradigmatic contrasts.     

Early maladaptive schemas in personality disordered individuals

The present study aimed to examine the specificity of schema domains in three personality disorder (PD) groups, namely borderline (BPD), obsessive-compulsive (OCPD), and avoidant PD (AvPD), and to correctly identify the three PD groups on the basis of these schemas. The sample consisted of 48 clinical participants diagnosed with PDs and assigned to 1 of 3 groups on the basis of their Axis II diagnoses (BPD: n = 13; OCPD: n = 13; AvPD: n = 22). High scores on Dependence/Incompetence, Defectiveness/ Shame and Abandonment were found for the BPD group. Such pattern appears to be most consistent with Young's theory of BPD. Consistent with the theory and empirical findings of Beck et al. (1990, 2001), OCPD was associated with elevations on the Unrelenting Standards schema domain, but not on Emotional Inhibition, which was found to be elevated for AvPD. In conclusion, the present study suggests that there are different patterns of schema domains across different PDs and that the Schema Questionnaire (SQ) is potentially useful in differentiating between these PDs.     

Word order in sentence processing: an experimental study of verb placement in German

We examine the question of whether the human comprehension device exhibits word-order preferences during on-line sentence comprehension. The focus is on the positioning of finite verbs and auxiliaries relative to subjects and objects in German. Results from three experiments (using self-paced reading and event-related brain potentials) show that native speakers of German prefer to process finite verbs in second position (i.e., immediately after the subject and before the object). We will account for this order preference in terms of the relative processing costs associated with SV_fO and SOV_f. Our finding that word-order preferences play an important role in the on-line comprehension of German sentences is compatible with results from previous studies on English and other languages.     

The processing of rhythmic structures in music and prosody by children with developmental dyslexia and developmental language disorder

Rhythm perception seems to be crucial to language development. Many studies have shown that children with developmental dyslexia and developmental language disorder have difficulties in processing rhythmic structures. In this study, we investigated the relationships between prosody and musical processing in Italian children with typical and atypical development. The tasks aimed to reproduce linguistic prosodic structures through musical sequences, offering a direct comparison between the two domains without violating the specificities of each one. About 16 Typically Developing children, 16 children with a diagnosis of Developmental Dyslexia, and 16 with a diagnosis of developmental language disorder (age 10–13 years) participated in the experimental study. Three tasks were administered: an association task between a sentence and its humming version, a stress discrimination task (between couples of sounds reproducing the intonation of Italian trisyllabic words), and an association task between trisyllabic nonwords with different stress position and three‐notes musical sequences with different musical stress. Children with developmental language disorder perform significantly lower than Typically Developing children on the humming test. By contrast, children with developmental dyslexia are significantly slower than TD in associating nonwords with musical sequences. Accuracy and speed in the experimental tests correlate with metaphonological, language, and word reading scores. Theoretical and clinical implications are discussed within a multidimensional model of neurodevelopmental disorders including prosodic and rhythmic skills at word and sentence level.     

Measurement invariance of the Phubbing Scale across 20 countries

Mobile phone addiction is a robust phenomenon observed throughout the world. The social aspect of mobile phone use is crucial; therefore, phubbing is a part of the mobile phone addiction phenomenon. Phubbing is defined as ignoring an interlocutor by glancing at one's mobile phone during a face-to-face conversation. The main aim of this study was to investigate how the Phubbing Scale (containing 10 items) might vary across countries, and between genders. Data were collected in 20 countries: Belarus, Brazil, China, Croatia, Ecuador, India, Israel, Italy, Netherlands, Pakistan, Poland, Portugal, Serbia, Slovakia, Slovenia, Spain, Turkey, UK, Ukraine and USA. The mean age across the sample (N = 7696, 65.8% women, 34.2% men) was 25.32 years (SD = 9.50). The cross-cultural invariance of the scale was investigated using multigroup confirmatory factor analyses (MGCFA) as well as the invariance analyses. Additionally, data from each country were assessed individually via confirmatory factor analyses (CFAs). We obtained two factors, based on only eight of the items: (a) communication disturbances and (b) phone obsession. The 8 items Phubbing Scale.     

Age differences in autobiographical memory across the adult lifespan: older adults report stronger phenomenology

As an individual’s life story evolves across adulthood, the subjective experience (phenomenology) of autobiographical memory likely changes. In addition to age at retrieval, both the recency of the memory and the age when a memory is formed may be particularly important to its phenomenology. The present work examines the effect of three temporal factors on phenomenology ratings: (a) age of the participant, (b) age at the event reported in the memory, and (c) memory age (recency). A large sample of Americans (N?=?1120), stratified by chronological age, recalled and rated two meaningful memories, a Turning Point and an Early Childhood Memory. Ratings of phenomenology (e.g., vividness of turning points) were higher among older adults compared to younger adults. Memories of events from the reminiscence bump were more positive in valence than events from other time periods but did not differ on other phenomenological dimensions; recent memories had stronger phenomenology than remote memories. In contrast to phenomenology, narrative content was generally unrelated to participant age, age at the event, or memory age. Overall, the findings indicate age-related differences in how meaningful memories are re-experienced.     

Cognitive constraints on motor imagery

Executed bimanual movements are prepared slower when moving to symbolically different than when moving to symbolically same targets and when targets are mapped to target locations in a left/right fashion than when they are mapped in an inner/outer fashion [Weigelt et al. (Psychol Res 71:238–447, 2007)]. We investigated whether these cognitive bimanual coordination constraints are observable in motor imagery. Participants performed fast bimanual reaching movements from start to target buttons. Symbolic target similarity and mapping were manipulated. Participants performed four action conditions: one execution and three imagination conditions. In the latter they indicated starting, ending, or starting and ending of the movement. We measured movement preparation (RT), movement execution (MT) and the combined duration of movement preparation and execution (RTMT). In all action conditions RTs and MTs were longer in movements towards different targets than in movements towards same targets. Further, RTMTs were longer when targets were mapped to target locations in a left/right fashion than when they were mapped in an inner/outer fashion, again in all action conditions. RTMTs in imagination and execution were similar, apart from the imagination condition in which participants indicated the start and the end of the movement. Here MTs, but not RTs, were longer than in the execution condition. In conclusion, cognitive coordination constraints are present in the motor imagery of fast (<1600 ms) bimanual movements. Further, alternations between inhibition and execution may prolong the duration of motor imagery.     

CRISPR/Cas9 genome editing – new and old ethical issues arising from a revolutionary technology

Although germline editing has been the subject of debate ever since the 1980s, it tended to be based rather on speculative assumptions until April 2015, when CRISPR/Cas9 technology was used to modify human embryos for the first time. This article combines knowledge about the technical and scientific state of the art, economic considerations, the legal framework and aspects of clinical reality. A scenario will be elaborated as a means of identifying key ethical implications of CRISPR/Cas9 genome editing in humans and possible ways of dealing with them. Unlike most other discussions of CRISPR/Cas9 germline editing, which are generally based on deontological arguments, the focus in this case will be on a consequentialistic argument against certain applications of germline and somatic editing that takes not only the potential benefits and risks but also socioeconomic issues into consideration. The practical need for an indication catalogue, guidelines for clinical trials, and for funding of basic research will be pointed out. It will be argued that this need for regulatory action and discussion does not stem primarily from the fact that CRISPR/Cas9 germline editing is revolutionary in terms of its ethical implications and potential for human therapy, although this is the prevailing view in the current discussion. Understanding the value and interest dependency of arguments put forward by different stakeholders and learning from past debates related to similar technologies might prove a fruitful method of reaching judgments and decisions that come closer to a consensus upon which society as a whole can agree - which after all should be the true goal of an ethical debate and of bioethics.     

Gaze behaviour in hereditary prosopagnosia

Prosopagnosia is the inability to recognize someone by the face alone in the absence of sensory or intellectual impairment. In contrast to the acquired form of prosopagnosia we studied the congenital form. Since we could recently show that this form is inherited as a simple monogenic trait we called it hereditary form. To determine whether not only face recognition and neuronal processing but also the perceptual acquisition of facial information is specific to prosopagnosia, we studied the gaze behaviour of four hereditary prosopagnosics in comparison to matched control subjects. This rarely studied form of prosopagnosia ensures that deficits are limited to face recognition. Whereas the control participants focused their gaze on the central facial features, the hereditary prosopagnosics showed a significantly different gaze behaviour. They had a more dispersed gaze and also fixated external facial features. Thus, the face recognition impairment of the hereditary prosopagnosics is reflected in their gaze behaviour.
