A Probabilistic Approach to Conditional Reasoning Development

How likely is the glass to break, given that it is heated? The present study asks questions such as this with or without the premise if the glass is heated, it breaks. A reduced problem (question without premise) measures the statistical dependency (conditional probability) of an event to occur, given that another has occurred. Such statistical dependency represents knowledge-based reasoning (inferring from “glass heated” to “its breaking”) and is a component of the response to the complete problem (question with premise). The complete problems therefore measure not only knowledge-based reasoning in terms of statistical dependencies (inductive component) but assumption-based reasoning (deductive component). Two experiments revealed: a) Knowledge-based reasoning continues to develop and attains adult levels at 7th grade for the problems tested, and b) assumption-based reasoning (deductive component) is reliable only for secondary school students (7th graders).     

The impact of parental discipline on the image of God

The purpose of this study was to examine the impact of parental discipline on men's and women's image of God – specially the degree to which they report perceiving God as loving, forgiving, trustworthy, and available. It compares the four major different parenting styles – authoritative, authoritarian, permissive/indulgent, and neglectful/rejecting – that people received during childhood on their perceptions of God when they are in college. Based on questionnaires completed by undergraduate students at a state university in Utah, this study found that parental discipline styles are related to individuals’ images of God to some extent. The results of a logistic regression show that parental discipline styles have differential impacts on the image of God between male and female respondents. For men, the image of God is significantly related to the parenting styles they received during their childhood, whereas for women, the relationship is not significant. Implications are discussed.     

Immigrant concentration and educational attainment: Evidence from US data

Ninety-five percent of the 30 million foreign-born persons living in the United States reside in a metropolitan area, and more than one half reside in just six gateway cities. We investigate whether less-educated immigrants tend to settle in large urban communities of their compatriots. Based on statistical analysis we find a negative relationship between the level of education and the size of immigrant population for the immigrants born in China, India, Philippines, Korea, El Salvador, Cuba, and Mexico. The relationship is strongest for Chinese, with a decrease of 2.7 years in average educational attainment for each tenfold increase in the size of immigrant community. Generally, this relationship is stronger for the immigrants from Asia and Latin America and nonexistent or mixed for immigrants from Europe and Canada.     

The in vitro immunomodulatory effects of glyconutrients on peripheral blood mononuclear cells of patients with chronic fatigue syndrome

In humans, eight monosaccharides are required for the synthesis of glycoproteins. Dietary supplements that supply these crucial sugars are known as glyconutrients. A glyconutrient compound was added to Peripheral Blood Mononuclear Cells (PBMC) isolated from normal controls and patients with the Chronic Fatigue Syndrome (CFS), a disease associated with immune dysregulation. The in vitro immunomodulatory effects were investigated. Cell surface expression of the glycoproteins CD5, CD8, and CD11a were significantly lower in patients with CFS compared to normal controls. Addition of glyconutrient homogenate to PBMC from patients with CFS stimulated with phytohemagglutinin significantly increased the expression of each glycoprotein. Furthermore, natural killer (NK) cell function was reduced in CFS patients. The glyconutrient preparation significantly enhanced NK cell activity versus human herpes virus 6 (HHV-6)-infected H9 cells in an 8 h⁵¹Cr release assay compared to placebo for PBMC from patients with CFS (p<.01). Finally, apoptosis was significantly higher in patients with CSF. The percentage of apoptotic cells was significantly decreased in PBMC from patients with CFS that had been incubated for 48 h with glyconutrients. Thus, glyconutrients improved abnormal immune parameters in vitro in patients with CFS. Dr. See is an Independent Mannatech Associate.     

Using intraverbal prompts to increase divergent intraverbal responses by a child with autism

We examined the effectiveness of intraverbal prompts to increase the number of divergent responses to categorical questions composed of compound stimuli (e.g., Name some red things) for a 6‐year‐old child with autism. The intraverbal prompts involved providing the function, feature, and class of the target responses. A multiple probe across behaviors design was used. Results indicated that the child's total number of divergent responses was increased and maintained during 2‐week follow‐up probe trials. Novel responses were observed across conditions.     

Branding ‘Canadian Experience’ in Immigration Policy: Nation Building in a Neoliberal Era

This paper examines the branding of ‘Canadian experience’ in Canadian immigration policy as a rhetorical strategy for neoliberal nation-building. Since 2008, the Canadian government has introduced an unprecedented number of changes to immigration policy. While the bulk of these policies produce more temporary and precarious forms of migration, the Canadian government has mobilized the rhetoric of ‘Canadian experience’ as a means to identify immigrants who carry the promise of economic and social integration. Through a critical discourse analysis of Canadian print media and political discourse, we trace how the brand of Canadian experience taps into the affective value of national identity in an era of global economic insecurity. We also illustrate how the discourse of Canadian experience (CE) remains ideologically deracialized, such that the government’s embrace of CE as an immigrant selection criterion dismisses the discriminatory effects that this discourse is shown to have for racialized immigrants in Canada.     

Neural mechanisms involved in the oral representation of percussion music: An fMRI study

Numerous music cultures use nonsense syllables to represent percussive sounds. Covert reciting of these syllable sequences along with percussion music aids active listeners in keeping track of music. Owing to the acoustic dissimilarity between the representative syllables and the referent percussive sounds, associative learning is necessary for the oral representation of percussion music. We used functional magnetic resonance imaging (fMRI) to explore the neural processes underlying oral rehearsals of music. There were four music conditions in the experiment: (1) passive listening to unlearned percussion music, (2) active listening to learned percussion music, (3) active listening to the syllable representation of (2), and (4) active listening to learned melodic music. Our results specified two neural substrates of the association mechanisms involved in the oral representation of percussion music. First, information integration of heard sounds and the auditory consequences of subvocal rehearsals may engage the right planum temporale during active listening to percussion music. Second, mapping heard sounds to articulatory and laryngeal gestures may engage the left middle premotor cortex.     

Location- and object-based inhibition of return are affected by different kinds of working memory

Castel, Pratt, and Craik (2003) have shown that inhibition of return (IOR, the delayed response to a recently cued item) is disrupted by a secondary task that involves spatial working memory (WM), and they suggest that IOR is mediated by spatial WM. However, they did not specify what kind of IOR was involved. We used a dual-task paradigm to examine whether the two kinds of IOR (location- and object-based IOR) are affected by two kinds of secondary task that involve spatial and nonspatial WM, respectively. The results show that location-based IOR was disrupted by a spatial secondary task while the object-based IOR was disrupted by a nonspatial secondary task. The present study further elaborates the conclusion of Castel et al. (2003) by differentiating the effect of the two kinds of WM (spatial vs. nonspatial) on the two kinds of IOR (location based vs. object based).     

The relationship of impairment to personality disorder severity among individuals with specific axis I disorders: results from the National Epidemiologic Survey on Alcohol and Related Conditions

The present study examined one dimensional approach to personality disorders (PDs) in a large (n = 43,093), nationally representative sample of the U.S. population. Respondents were classified in four personality severity categories (no PD, subthreshold PD, simple PD, complex PD). Linear regression analyses were conducted to examine mental disability by PD severity for major DSM-IV substance use, mood and anxiety disorders. Significant increases in disability were observed between no PD and simple PD and between simple PD and complex PD for each Axis I disorder except drug dependence, but few differences in disability were found between no PD and subthreshold PD. This study found support for the clinical utility of the dimensional classification of PD severity with regard to the distinction between simple and complex PD and for a combined no PD-subthreshold PD level of severity. Future planned analyses will address the clinical utility of the classification prospectively, with a full battery of all Axis II PDs.     

Does mood state change risk taking tendency in older adults?

No study has been conducted to evaluate the influences of age differences on specific moods for risk taking tendencies. This study examined the patterns of risk taking tendencies among younger and older persons in 3 transient affective states: positive, neutral, and negative moods. By means of viewing happy, neutral, or sad movie clips, participants were induced to the respective mood. Risk taking tendencies were measured with decision tasks modified from the Choice Dilemmas Questionnaire (N. Kogan & M. A. Wallach, 1964). Consistent with the affect infusion model (J. P. Forgas, 1995), risk taking tendency was greater for those individuals who were in a happy mood than for those who were in a sad mood, for both young and older participants. However, an asymmetrical effect of positive and negative mood on risk taking tendency was identified among both the young and older participants, but in opposite directions. These results are consistent with the predictions of the negativity bias and the positivity effect found in young and older adults, respectively, and are interpreted via information processing and motivation effects of mood on the decision maker.
