Executive functioning deficits in relation to symptoms of ADHD and/or ODD in preschool children

The present study investigated the relation between executive functioning and symptoms of Attention‐Deficit/Hyperactivity Disorder (ADHD) and Oppositional Defiant Disorder (ODD) in children aged 4–6. A population‐based sample (n=201) was used and laboratory measures of inhibition, working memory and verbal fluency and teacher ratings of disruptive behaviour problems were collected. Both group differences and linear relations were studied and comorbidity was controlled for dimensionally. In both categorical and dimensional analyses, executive functioning was associated with symptoms of ADHD, but not with symptoms of ODD when controlling for comorbidity, and no significant interactive effects of ADHD and ODD symptoms were found. Effect sizes for significant effects were generally in the medium range. Regarding sex differences, the control for comorbid ODD symptoms appeared to affect the relation between ADHD symptoms and executive functioning somewhat more for girls compared with boys. In conclusion, poor executive functioning in preschool appears to be primarily related to symptoms of ADHD, whereas the relation to symptoms of ODD can be attributed to the large overlap between these two disruptive disorders.

“Not a Source but a Re-source”: The Ethics of Reading, Teaching, and Interpreting Beyond the Boundaries

Critical interest in Aboriginal and other non-mainstream works challenges established notions of literariness and canonicity, spilling over into the classroom and curriculum development, where instructors of various disciplines must make decisions about what they will teach, and how and why they will teach it. The ramifications of such decisions are multifaceted and often compounded by fear, raising concerns regarding the scope and the ways in which teachers or post-secondary instructors are accountable for the ethical treatment of texts by so-called minority writers and to the broadening demographic of students. Teachers/instructors must themselves construct an ethical framework for inclusion of texts for study, and often do so with only tenuous support. For example, what are the rights of educators to engage with texts that fall outside of their cultural experience? If instructors are not exempt from the ethical considerations facing researchers, how do they become accountable without excluding or appropriating contentious materials in the scope of their work? Liberatory pedagogical practices in the classroom provide the backdrop against which an ethics of inclusion can develop and consequently inform the development of curricula and the creation of syllabi, as well as the facilitation of classroom dynamics in an atmosphere of cultural richness and diversity.     

The Effect of Training on Multicultural Counseling Competencies: An Exploratory Study Over a Ten‐Year Period

The impact of integrated multicultural internship training on multicultural counseling competencies was evaluated. Multicultural Counseling Awareness Scale (MCAS:B; J. G. Ponterotto, C. M. Sanchez, & D. M. Magids, 1991) scores were obtained at the beginning and end of internship. Knowledge/Skills scores significantly increased at the end of training. Implications for training, measurement, and research with multicultural counseling competencies are discussed. El impacto de integrar las competencias de consejería multicultural en el entrenamiento de internados de psicología, fué evaluado. Los resultados de internos en la Escala de Consciencia de Consejería Multicultural (MCAS:B; J. G. Ponterotto, C. M. Sanchez, & D. M. Magids, 1991) fueron obtenidos al principio y al final del entrenamiento. Al fin del entrenamiento los resultados de las technica/conocimientos aumentaron significamente. Consideraciones para el entrenamiento, la medición e investigación de las competencias de consejería multicultural son discutidas.     

Imitation in infancy: the wealth of the stimulus

Imitation requires the imitator to solve the correspondence problem--to translate visual information from modelled action into matching motor output. It has been widely accepted for some 30 years that the correspondence problem is solved by a specialized, innate cognitive mechanism. This is the conclusion of a poverty of the stimulus argument, realized in the active intermodal matching model of imitation, which assumes that human neonates can imitate a range of body movements. An alternative, wealth of the stimulus argument, embodied in the associative sequence learning model of imitation, proposes that the correspondence problem is solved by sensorimotor learning, and that the experience necessary for this kind of learning is provided by the sociocultural environment during human development. In a detailed and wide-ranging review of research on imitation and imitation-relevant behaviour in infancy and beyond, we find substantially more evidence in favour of the wealth argument than of the poverty argument.     

Tufted titmouse (Baeolophus bicolor) calling and risk-sensitive foraging in the face of threat

Individuals often produce alarm or mobbing calls when they detect a threat such as a predator. Little is known about whether such calling is affected by the facial orientation of a potential threat, however. We tested for an effect of facial orientation of a potential threat on tufted titmice, Baeolophus bicolor, a songbird that uses chick-a-dee calls in a variety of social contexts. In two studies, a human observer wore an animal mask that either faced or faced away from the focal bird(s). In Study 1, focal birds were individual titmice captured in a walk-in trap, and the observer stood near the trapped bird. In Study 2, focal birds were titmouse flocks utilizing a feeding station and the observer stood near the station. In both studies, calling behavior was affected by mask orientation. In Study 2, foraging and agonistic behavior were also affected. Titmice can therefore perceive the facial orientation of a potential threat, and this perception affects different behavioral systems, including calling. Our results indicate sensitivity of titmice to the facial orientation of a potential predator in two quite different motivational contexts. This work suggests the possibility of strategic signaling by prey species depending upon the perceptual space of a detected predator.     

Where Am I? A new case of developmental topographical disorientation

Recently, developmental topographical disorientation (DTD) was described (Bianchini et al., 2010, J Clin Exp Neuropsychol, 20, 807–27; Iaria & Barton, 2010, Exp Brain Res, 206, 189–96; Iaria, Bogod, Fox, & Barton, 2009, Neuropsychologia, 47, 30–40) as a navigational deficit in the absence of neurological or psychiatric disorders. Here, we reported the case of a healthy subject who presented this disorder. Dr. WAI was a 29‐year‐old right‐handed man with normal development and no clinical history of neurological or psychiatric diseases who was affected by a very pervasive topographical orientation and navigational disorder. A neuroradiological exam confirmed the absence of structural and anatomical alterations of the brain. Dr. WAI was submitted to an extensive neuropsychological examination and to a battery of tests specifically developed to assess developmental topographical disorder. Using this battery, we analysed Dr. WAI's acquisition of navigational information and re‐orientation processes. He showed severe DTD accompanied by deficits of different cognitive processes directly or indirectly involved in navigational skills. Dr. WAI showed a deficit in developing cognitive maps, already found in previous cases, plus difficulties in evaluating distances and computing metric environmental features. He represents a further confirmation of the existence of DTD suggesting dissociations within the disorder related to the level of development of the ability to build cognitive maps and the association of different imagery deficits. Dr. WAI can help in shedding some light on the mechanisms underlying lack of development of navigational skills.     

Quality of Life and Bladder Management post Spinal Cord Injury: A Systematic Review

To explore the relationship between neurogenic bladder management techniques and quality of life (QoL) among individuals with spinal cord injury (SCI). A key terms literature search was conducted in multiple electronic databases (i.e., MEDLINE, CINAHL, EMBASE, and PsycINFO). Studies published up to and including May 2013 were reviewed and evaluated based on the following criteria: (1) full-length journal article published in the English language; (ii) human subjects ≥18 years; (iii) ≥?50 % of subjects had a SCI; (iv) results on QoL, as it related to bladder management method, were reported for at least three subjects. A total of 422 articles were extracted and upon review of titles and abstracts, 7 studies met the inclusion criteria. There were two level 2 cohort studies and five level 5 observational studies. Sample sizes ranged from 37 to 282 with an average of 117.1 individuals per study. All participants were at least six months post injury. Bladder management methods used included intermittent (patient/attendant), indwelling (suprapubic/transurethral), and condom catheterization, micturition assistive maneuvers, and electrical stimulation. Normal voiders scored better in all QoL measure domains compared to other management methods. Those using attendant intermittent and indwelling catheterization scored the poorest on the domains Personal Relationships, Emotions, and Mental Health. There is insufficient evidence to provide a definite conclusion as to the relationship between bladder management methods and QoL post SCI. However, individuals relying on others to aid in voiding may experience lower QoL compared to those who are independent.     

Client Views and Attitudes to Non-Invasive Prenatal Diagnosis for Sickle Cell Disease,Thalassaemia and Cystic Fibrosis

In the near future the availability of non-invasive prenatal diagnosis (NIPD) for single gene disorders will change the prenatal diagnosis options available to couples who are carriers of conditions such as cystic fibrosis, sickle cell disorder and thalassaemia. Client opinions about NIPD are needed to inform the implementation of NIPD for single gene disorders. This qualitative study used two focus groups (n?=?12) and one-to-one interviews (n?=?16) with carriers and support group representatives of sickle cell disease, thalassaemia and cystic fibrosis. Discussions were digitally recorded, transcribed verbatim and analysed using thematic analysis. Opinions about NIPD were very positive and participants valued the opportunity to have safe and early testing. Uptake of prenatal testing is likely to increase as women who had previously declined invasive testing expressed interest in having NIPD. Participant concerns about NIPD centred on the need for accuracy to be high to be used for subsequent decision making about termination of pregnancy. Participants also raised concerns that less thought may be given to having a blood test compared to an invasive test and that the perceived ease of a blood test may bring increased pressure to have testing. Participants thought NIPD should be offered through existing specialist services to ensure appropriate genetic counseling and support. Maintaining all testing options is important as some people may prefer invasive testing over NIPD if invasive testing was more accurate or if invasive testing could give information about other conditions such as Down syndrome.
