Distinct Pathways From Parental Beliefs and Practices to Children’s Numeric Skills

It is imperative to identify contextual factors contributing to the development of early math skills, considering their role in later academic achievement. To pursue this goal, the present study investigated the paths connecting parental beliefs and practices during the preschool years to children’s numeric skills at the end of kindergarten (N = 98). Results were consistent with theoretical predictions of specific relations between particular types of parental input and different aspects of number knowledge. Direct math learning activities mediated the relation between parental beliefs and children’s number identification skills. Daily activities involving quantitative components mediated the relation between parental beliefs and children’s numerical magnitude understanding. Both types of activities predicted arithmetic skills that integrate the basic aspects of symbolic number knowledge. These findings contribute to developmental theory by specifying how characteristics of children’s environments are related to particular aspects of their development, which is critical for informing intervention work to improve early math skills.     

<Emphasis Type="Italic">StimulStat</Emphasis>: A lexical database for Russian

In this article, we present StimulStat – a lexical database for the Russian language in the form of a web application. The database contains more than 52,000 of the most frequent Russian lemmas and more than 1.7 million word forms derived from them. These lemmas and forms are characterized according to more than 70 properties that were demonstrated to be relevant for psycholinguistic research, including frequency, length, phonological and grammatical properties, orthographic and phonological neighborhood frequency and size, grammatical ambiguity, homonymy and polysemy. Some properties were retrieved from various dictionaries and are presented collectively in a searchable form for the first time, the others were computed specifically for the database. The database can be accessed freely at http://stimul.cognitivestudies.ru.     

The status of consonants and vowels in phonological assembly: Testing the two-cycles model with Italian

Recent studies by Berent and Perfetti (1995) and Lee, Rayner, and Pollatsek (2001) have shown a processing priority of consonants over vowels in tasks like backward masking and reading, respectively. One possible explanation for this advantage of consonants is in terms of the specific characteristics of the English spelling (i.e., a great inconsistency in the spelling-sound relations for vowels), and therefore is not predicted for a language, like Italian, with a transparent orthography. The aim of the present experiments was to investigate the consonant advantage in Italian with the backward masking paradigm. The first two experiments, with a perceptual identification and a naming task, showed a masking reduction effect for masks sharing vowels with the target at the shortest SOAs, in addition to a pseudo-homophone advantage as compared to the control condition. In the third experiment, where a lexical decision task was used, the advantage of the mask sharing vowels disappeared. The fourth experiment was a replication of Experiment 1 with different materials. Overall, the results suggest that the advantage of consonants can only be found in English, whereas in Italian, for which the computation of phonology of vowels and consonants is similar, no effect is apparent. Thus, the processing priority for consonants seems to depend on the inconsistencies of vowel phonology in English.     

The Effectiveness of Coping Power Program for ADHD: An Observational Outcome Study

The present study evaluates the implementation of the Coping Power Program (CPP)-Child Component in a group of patients with attention deficit/hyperactivity disorder (ADHD), and explores the effects of this treatment on changes in the primary and associated symptoms of ADHD. A clinical sample of 50 children and preadolescents (8–13 years) with ADHD was involved. The clinical sample was split into a treatment group (TG; N?=?26), which was included in the child training program (CPP), and a control group (CG; N?=?24), which was placed on a waiting list. The Clinical Global Impression-Severity (CGI-S) and the Child Behavior Checklist 6–18 (CBCL 6–18) were assessed at baseline and at the end of treatment. The outcomes were assessed as a CBCL-subscale response rate and a CGI-S shift. Our results showed a significant improvement in children’s global functioning and in emotional and behavioral symptoms. The children in the TG were more likely to shift from a more severe functional impairment class to a less severe one (69.2% of TG vs. 20.8% of CG). Further, the CGI-S scores diminished significantly in the TG (p?<?0.01). There were significant differences in the changes in Social Problems (p?<?0.05), Attention Problems (p?<?0.05) and Rule-Breaking Behavior Scales (p?<?0.05). CPP seemed to be effective in children and adolescents with ADHD without comorbidity for ODD or CD. Our study revealed an improved outcome, not only in the core symptoms of ADHD, but also in global functioning and social adjustment. Possible improvements to the present formulation of CPP-C are discussed.     

Is desynchrony tolerance adaptable in the perceptual organization of speech?

Speech signal components that are desynchronized from the veridical temporal pattern lose intelligibility. In contrast, audiovisual presentations with large desynchrony in visible and audible speech streams are perceived without loss of integration. Under such conditions, the limit of desynchrony that permits audiovisual integration is also adaptable. A new project directly investigated the potential for adaptation to consistent desynchrony with unimodal auditory sine-wave speech. Listeners transcribed sentences that are highly intelligible, with veridical temporal properties. Desynchronized variants were created by leading or lagging the tone analog of the second formant relative to the rest of the tones composing the sentences, in 50-msec steps, ranging from 250-msec lead to 250-msec lag. In blocked trials, listeners only tolerated desynchronies <50 msec, and exhibited no gain in intelligibility to consistent desynchrony. Unimodal auditory and bimodal audiovisual forms of perceptual integration evidently exhibit different temporal characteristics, an indication of distinct perceptual functions.     

Sex differences in developmental trends of suicide ideation, plans, and attempts among European American adolescents

Although suicide ideation, plans, and attempts increase during adolescence, it remains unclear whether boys' and girls' risk for these outcomes peaks at different ages. We used longitudinal categorical data (never, once, 2+ times) from the Family Transitions Project (N = 1,248 rural European Americans, ages 11-19) to investigate whether yearly prevalence rates of adolescent suicidal episodes follow different patterns by sex. Multiple-group growth models revealed that peak levels of past-year ideation and plans occurred during mid adolescence for girls, but slowly increased through late adolescence for boys. We found that prevalence patterns for attempts were very similar for boys and girls, with both increasing through mid adolescence and then declining, although girls' risk declined slightly more rapidly. This information may help alert gatekeepers to developmental periods during which boys and girls are particularly vulnerable to suicide-related experiences, and also may help inform the timing of preventive efforts.     

Motivating minority older adults to exercise

The purpose of this qualitative study was to explore with minority older adults their experience in the Senior Exercise Self-Efficacy Pilot Program (SESEP) and establish what aspects of the SESEP helped the participants engage in exercise and what decreased their willingness to exercise. A total of 148 older adults from 12 Senior Centers participated. The majority of the participants were African American (77%), and female (79%) and the average age was 72.9+/-8.0. Analysis of the semi-structured interviews revealed 36 codes which were categorized and reduced to 13 major themes. Eleven of these themes focused on factors that facilitated participation in exercise and two themes included factors that decreased willingness to participate in exercise. Findings support the use of the theory of self-efficacy to change behavior among minority older adults, and future research should focus on identifying culturally specific interventions that will strengthen these beliefs and thereby increase exercise behavior.
