Spanish developmental dyslexia: Prevalence, cognitive profile, and home literacy experiences

This study was designed to examine the prevalence, cognitive profile, and home literacy experiences in subtypes of Spanish developmental dyslexia. The subtyping procedure used comparison with chronological-age-matched and reading-level controls on reaction times and accuracy responses to high-frequency words and pseudowords. Using regression-based procedures, 8 phonological dyslexics and 16 surface dyslexics were identified from a sample of 35 dyslexic fourth graders by comparing them with chronological-age-matched controls on reaction times to high-frequency word and pseudoword reading. However, when the dyslexic subtypes were defined by reference to reading-level controls, 12 phonological dyslexics were defined but only 5 surface dyslexics were identified. Both dyslexic subtypes showed a deficit in phonological awareness, but children with surface dyslexia also showed a deficit in orthographical processing assessed by a homophone comprehension task. This deficit was associated with poor home literacy experiences, with the group of parents with children matched in reading age, in comparison with the group of parents with children with surface dyslexia, reporting more literacy home experiences.     

Early detection of drug use and bullying in secondary school children by using a three-dimensional simulation program

The current study analyzes the psychometric properties of an innovative three-dimensional (3D) simulation program, entitled Mii-School (MS), designed for the early detection of drug use and bullying in Secondary School children. This computer program showed adequate reliability and construct validity. The factorial structure, as well as the explanatory weight of the different factors, is presented. In addition, the results of a parallel version in paper and pencil format are also presented and compared with those of the computerized version (i.e., MS). There was a statistically significant difference between the two formats in the total (i.e., combined) sore of risk. When drug use and bullying were separately analyzed, differences were found only with regard to drug use. The relevance of these results as well as the suitability of this type of 3D instrument for the early detection of risky behaviors in young people are discussed.     

Athletes’ Preferred Characteristics and Qualifications of Sport Psychology Practitioners: A Consumer Market Analysis

Studies assessing the perceived characteristics of competent sport psychology practitioners have resulted in skewed data, making it difficult to discern the relative importance of each characteristic. Therefore, the purpose of this study was to assess the attributes of gender, ethnicity, interpersonal skills, physical appearance, athletic background, professional status, and sport culture in relation to one another using conjoint analysis, a consumer market analysis. College student athletes (N = 464) indicated a preference for a female practitioner whose ethnicity matched that of the athlete and possessed high interpersonal skills and sport knowledge, an athletic background, a physically fit body type, and had earned a professional degree. These findings can be used by sport psychology consultants to modify the information they give to current clients and to develop marketing plans to appeal to potential clients.     

Psychometric Properties of the Child Posttraumatic Cognitions Inventory in a Sample of Brazilian Children

Cognitive models of trauma propose that maladaptive cognitions in children and adolescents are causally implicated in the unfolding and maintenance of posttraumatic response. The objective of this study was to evaluate the psychometric properties of the Child Posttraumatic Cognitions Inventory (CPTCI). The sample included 131 children and adolescents. The psychometric properties of the CPTCI were examined, including reliability and convergent validity. The results showed high internal consistency for both CPTCI total scale (α = .90) and its subscales (CPTCI–PC α = .88 and CPTCI–SW α = .79) and a 2-component solution explaining 37.63% of the variance of CPTCI. Convergent validity evidence was obtained through correlations with the Trauma Symptom Checklist for Children and Children’s Depression Inventory. Findings suggest that CPTCI instruments are reliable and had adequate evidence of validity.     

Mouse vocal communication system: Are ultrasounds learned or innate?

Mouse ultrasonic vocalizations (USVs) are often used as behavioral readouts of internal states, to measure effects of social and pharmacological manipulations, and for behavioral phenotyping of mouse models for neuropsychiatric and neurodegenerative disorders. However, little is known about the neurobiological mechanisms of rodent USV production. Here we discuss the available data to assess whether male mouse song behavior and the supporting brain circuits resemble those of known vocal non-learning or vocal learning species. Recent neurobiology studies have demonstrated that the mouse USV brain system includes motor cortex and striatal regions, and that the vocal motor cortex sends a direct sparse projection to the brainstem vocal motor nucleus ambiguous, a projection previously thought be unique to humans among mammals. Recent behavioral studies have reported opposing conclusions on mouse vocal plasticity, including vocal ontogeny changes in USVs over early development that might not be explained by innate maturation processes, evidence for and against a role for auditory feedback in developing and maintaining normal mouse USVs, and evidence for and against limited vocal imitation of song pitch. To reconcile these findings, we suggest that the trait of vocal learning may not be dichotomous but encompass a broad spectrum of behavioral and neural traits we call the continuum hypothesis, and that mice possess some of the traits associated with a capacity for limited vocal learning.     

from the common thug to the local businessman: an exploration into an urban african american barbershop

This ethnographic study investigates the social interactions that transpire in an urban African American barbershop, called Peanut's, located in a Southern city. The results of this study indicate that the urban African American barbershop has the potential to be a place where any number of activities can and do take place. Specifically, this study discovered three levels of the underground economy (i.e., legal, quasi-legal, and illegal) with each level reflecting a different degree of criminal potential.     

Visual laterality in belugas (Delphinapterus leucas) and Pacific white-sided dolphins (Lagenorhynchus obliquidens) when viewing familiar and unfamiliar humans

Lateralization of cognitive processes and motor functions has been demonstrated in a number of species, including humans, elephants, and cetaceans. For example, bottlenose dolphins (Tursiops truncatus) have exhibited preferential eye use during a variety of cognitive tasks. The present study investigated the possibility of visual lateralization in 12 belugas (Delphinapterus leucas) and six Pacific white-sided dolphins (Lagenorhynchus obliquidens) located at two separate marine mammal facilities. During free swim periods, the belugas and Pacific white-sided dolphins were presented a familiar human, an unfamiliar human, or no human during 10–15 min sessions. Session videos were coded for gaze duration, eye presentation at approach, and eye preference while viewing each stimulus. Although we did not find any clear group level lateralization, we found individual left eye lateralized preferences related to social stimuli for most belugas and some Pacific white-sided dolphins. Differences in gaze durations were also observed. The majority of individual belugas had longer gaze durations for unfamiliar rather than familiar stimuli. These results suggest that lateralization occurs during visual processing of human stimuli in belugas and Pacific white-sided dolphins and that these species can distinguish between familiar and unfamiliar humans.
