Self-motion perception influences number processing: evidence from a parity task

We investigated the role of horizontal body motion on the processing of numbers. We hypothesized that leftward self-motion leads to shifts in spatial attention and therefore facilitates the processing of small numbers, and vice versa, we expected that rightward self-motion facilitates the processing of large numbers. Participants were displaced by means of a motion platform during a parity judgment task. We found a systematic influence of self-motion direction on number processing, suggesting that the processing of numbers is intertwined with the processing of self-motion perception. The results differed from known spatial numerical compatibility effects in that self-motion exerted a differential influence on inner and outer numbers of the given interval. The results highlight the involvement of sensory body motion information in higher-order spatial cognition.     

Examining the components and concomitants of parental structure in the academic domain

Self-Determination Theory posits and research supports that caregiver autonomy support, involvement, and structure facilitate children’s motivation and well-being. However, to attain a comprehensive understanding of these caregiving behaviors and thus make informed practical recommendations, their key components must be identified. While a significant literature examines autonomy support and involvement, structure has been less extensively researched. This study thus attempted to provide an in-depth exploration of parental structure. Drawing from past literature, six components were identified. Seventy-five seventh and eighth graders completed semi-structured interviews and students and parents completed questionnaires assessing structure, other parenting dimensions, and motivational outcomes in the academic domain. Findings indicate that structure (a) is multi-faceted, (b) is independent from autonomy support, and (c) makes unique contributions to children’s motivation and school performance. Implications for providing facilitative contexts for children’s motivation and success as well as for future work are discussed.     

The link between ego-resiliency and changes in Big Five traits after decision making: The case of Extraversion

After performing such solitary decision making tasks as the Iowa Gambling Task (IGT) and the Game of Dice Task (GDT), we expected that changes will occur in Extraversion trait measured by a short Hungarian Big Five Inventory (BFI). We also hypothesized that ego-resiliency (Block, 2002)—a dimension measuring the ability to adapt to situational demands—will be linked to the magnitude of Extraversion change. After a pre-task measurement of the Big Five traits and ego-resiliency, participants (N = 93) completed the IGT and the GDT tasks. After each task, they filled out the BFI again. Pre- and post-task Big Five trait values showed significant differences. Participants reported lower post task scores on the Extraversion dimension and the magnitude of Extraversion change between pre- and post-task measurements correlated with ego-resiliency. The results highlight some short term effects of contextual factors influencing self-characterizations in BFI dimensions. Especially, individuals with high ego-resiliency give characteristically more introverted self-characterization after solitary tasks. The present results show an example of how the interplay between contextual factors and ego-resiliency can modify self-characterization within a very short period of time.     

What is Externalism?

The content of the externalist thesis about the mind depends crucially on how we define the distinction between the internal and the external. According to the usual understanding, the boundary between the internal and the external is the skull or the skin of the subject. In this paper I argue that the usual understanding is inadequate, and that only the new understanding of the external/internal distinction I suggest helps us to understand the issue of the compatibility of externalism and privileged access.     

The effects of attention and task-relevance on the processing of syntactic violations during listening to two concurrent speech streams

The notion of automatic syntactic analysis received support from some event-related potential (ERP) studies. However, none of these studies tested syntax processing in the presence of a concurrent speech stream. Here we present two concurrent continuous speech streams, manipulating two variables potentially affecting speech processing in a fully crossed design: attention (focused vs. divided) and task (lexical – detecting numerals vs. syntactical – detecting syntactic violations). ERPs elicited by syntactic violations and numerals as targets were compared with those for distractors (task-relevant events in the unattended speech stream) and attended and unattended task-irrelevant events. As was expected, only target numerals elicited the N2b and P3 components. The amplitudes of these components did not significantly differ between focused and divided attention. Both task-relevant and task-irrelevant syntactic violations elicited the N400 ERP component within the attended but not in the unattended speech stream. P600 was only elicited by target syntactic violations. These results provide no support for the notion of automatic syntactic analysis. Rather, it appears that task-relevance is a prerequisite of P600 elicitation, implying that in-depth syntactic analysis occurs only for attended speech under everyday listening situations.     

Two Versions of the Extended Mind Thesis

According to the Extended Mind thesis, the mind extends beyond the skull or the skin: mental processes can constitutively include external devices, like a computer or a notebook. The Extended Mind thesis has drawn both support and criticism. However, most discussions??including those by its original defenders, Andy Clark and David Chalmers??fail to distinguish between two very different interpretations of this thesis. The first version claims that the physical basis of mental features can be located spatially outside the body. Once we accept that the mind depends on physical events to some extent, this thesis, though not obvious, is compatible with a large variety of views on the mind. The second version applies to standing states only, and has to do with how we conceive the nature of such states. This second version is much more interesting, because it points to a potential tension in our conception of minds or selves. However, without properly distinguishing between the two theses, the significance of the second is obscured by the comparative triviality of the first.     

Talking to Children About Maternal BRCA1/2 Genetic Test Results: A Qualitative Study of Parental Perceptions and Advice

Family communication is the primary, initial means of educating the next, at-risk generation about hereditary cancer risk. In this study, in-depth parent narratives provided self-report of motivations, planning, satisfactions and regrets associated with sharing or not sharing maternal BRCA1/2 test results with young children and advice for parents considering disclosure and for genetic counselors. Interviews were conducted with 32 mothers tested for BRCA1/2 with children ages 8–21 years and 24 of their co-parents; interview narratives were analyzed qualitatively. Parents were concerned with both protecting and educating children about hereditary cancer risk. They expressed confidence that parents can constructively convey genetic information to minor children. Telling relieved most parents and satisfied a sense of parental duty. Parents strongly advised child-specific, age-appropriate tailoring of genetic information and emphasized conveying the positive, preventive utility of genetic information to children. Immunizing effects of disclosure were viewed as providing forewarning about and preparation for possible later family cancer diagnoses. Parents choosing not to tell children were advised to consider future disclosure. Narratives about parental sharing of BRCA1/2 test results with minor children support the feasibility of parental discussion of maternal genetic test results to the next at-risk generation. Results suggest development of intervention tools for parents would support decision-making and family communication and potentially reduce parental worry and regret. Recommendations are made for more active involvement by genetic counselors with tested parents around the topic of delivery of genetic information to children.     

The utility of the structured interview of reported symptoms in a sample of individuals with intellectual disabilities

The challenges of accurate forensic assessment are aggravated when evaluatees have intellectual disabilities. Few studies have addressed the efficacy of forensic assessment in samples diagnosed with an intellectual disability, and those that have typically focus on measures of cognitive effort rather than on feigned psychiatric symptoms. This study focuses on the applicability of the original and revised versions of the Structured Interview of Reported Symptoms (SIRS) in a sample of participants with genuine intellectual disabilities. The SIRS was administered to 43 individuals diagnosed with intellectual disabilities, all of whom were asked to respond honestly. A considerable proportion of these respondents were misclassified as feigning psychiatric symptoms. These misclassifications were most frequent when the respondents had comorbid psychiatric diagnoses. The updated scoring algorithm of the SIRS-2 generated a rate of misclassifications that was substantially lower but that still exceeded published normative data. The implications for forensic assessment are discussed.     

Ethical Issues in Cancer Genetics: 1) Whose Information Is It?

This article presents and discusses four clinical cases that exemplify the complexity of ethical dilemmas concerning the provider's obligation to disclose or withhold genetic information from patients. Case 1: What is the responsibility of the cancer genetics provider to ensure that a positive test results is shared with distant relatives? Case 2: To ensure that results go to at-risk relatives, do we have the right to ignore the wishes of the designated next-of-kin? Case 3: Do we have the right to reveal a familial BRCA1 mutation to a patient's relative, who is at 50% risk? Case 4: Do we have an obligation to reveal that a patient is not a blood relative and therefore, not at risk to have inherited a familial mutation? These cases form the basis for discussing the provider's dual obligations to keeping patient confidentiality and informing patients and families about risk (i.e. duty to warn). We also provide a summary of consensus points and additional discussion questions for each case.
