Adaptation of parent-child interaction therapy for Puerto Rican families: a preliminary study

This study examines how parent-child interaction therapy (PCIT) was adapted for Puerto Rican parents of children aged 4-6 with hyperactivity and other significant behavior problems. Four steps were followed: (1) translation and preliminary adaptation of the treatment manual, (2) application of the treatment to 9 families as part of an exploratory study using repeated measures, (3) treatment revision and refinement, and (4) in-depth interviews with parents (n=15) and clinical psychologists (n=5) from Puerto Rico who provided feedback on treatment process and components. Throughout this process, cultural elements and modifications were recommended to be incorporated into the treatment protocol. Both quantitative and qualitative results suggest that PCIT seems to be an acceptable intervention for this population, with some minor changes. Parents reported a high level of satisfaction, a significant reduction in children's externalizing behavior problems, and reduction of parenting stress and improvement in their parenting practices. Psychologists also evaluated positively the treatment protocol and recommended its use. Results from this study may inform clinicians and researchers who work with Latino families about relevant issues to be considered to promote their participation in behavioral family interventions and to enhance their acceptability and effectiveness.     

Measuring individual and cultural differences in implicit trait theories

A new measure of implicit theories or beliefs regarding the traitedness versus contextuality of behavior was developed and tested across cultures. In Studies 1 (N = 266) and 2 (N = 266), these implicit beliefs dimensions were reliably measured and replicated across U.S. college student samples and validity evidence was provided. In Study 3, their structure replicated well across an individualistic culture (the United States; N = 249) and a collectivistic culture (Mexico; N = 268). Implicit trait and contextual beliefs overlapped only modestly with implicit entity theory beliefs and were predicted by self-construals in ways that generally supported cultural psychology hypotheses. Implicit trait beliefs were fairly strongly endorsed in both cultures, suggesting that such beliefs may be universally held.     

Hippocampal gene expression profiling in spatial discrimination learning

Learning and long-term memory are thought to involve temporally defined changes in gene expression that lead to the strengthening of synaptic connections in selected brain regions. We used cDNA microarrays to study hippocampal gene expression in animals trained in a spatial discrimination-learning paradigm. Our analysis identified 19 genes that showed statistically significant changes in expression when comparing Nai;ve versus Trained animals. We confirmed the changes in expression for the genes encoding the nuclear protein prothymosin(alpha) and the delta-1 opioid receptor (DOR1) by Northern blotting or in situ hybridization. In additional studies, laser-capture microdissection (LCM) allowed us to obtain enriched neuronal populations from the dentate gyrus, CA1, and CA3 subregions of the hippocampus from Nai;ve, Pseudotrained, and spatially Trained animals. Real-time PCR examined the spatial learning specificity of hippocampal modulation of the genes encoding protein kinase B (PKB, also known as Akt), protein kinase C(delta) (PKC(delta)), cell adhesion kinase(beta) (CAK(beta), also known as Pyk2), and receptor protein tyrosine phosphatase(zeta/beta) (RPTP(zeta/beta)). These studies showed subregion specificity of spatial learning-induced changes in gene expression within the hippocampus, a feature that was particular to each gene studied. We suggest that statistically valid gene expression profiles generated with cDNA microarrays may provide important insights as to the cellular and molecular events subserving learning and memory processes in the brain.     

Development of an ethanol model using social insects: II. Effect of Antabuse on consumatory responses and learned behavior of the honey bee (Apis mellifera L.)

The ability of Antabuse (disulfiram) to influence ethanol consumption and learning in harnessed honey bees was investigated. In the first series of experiments a factorial design was used with 5 levels of ethanol concentration (0%, 1%, 5%, 10%, 20%), 4 doses of Antabuse (0, 37 microg/g, 3.7 microg/g, .37 microg/g), and 2 testing intervals (1 min., 10 min.). Animals were fed a single 1 microl dose of Antabuse and contact time with an ethanol solution measured. A second series of experiments investigated the influence of Antabuse on the formation of Pavlovian conditioning of the proboscis extension reflex. A factorial design was used with two levels of training (paired, unpaired), three levels of ethanol (0%, 1%, 5%), and 2 levels of pretreatment (distilled water, 3.7 microg/g). Analysis of the consumption experiments indicate that pretreatment with Antabuse reduces ethanol intake, although there was substantial variability. The findings of the Pavlovian experiments suggest that pretreatment with Antabuse significantly reduced responding to a CS signaling the availability of ethanol.     

Multinational data show that conspiracy beliefs are associated with the perception (and reality) of poor national economic performance

While a great deal is known about the individual difference factors associated with conspiracy beliefs, much less is known about the country-level factors that shape people's willingness to believe conspiracy theories. In the current article we discuss the possibility that willingness to believe conspiracy theories might be shaped by the perception (and reality) of poor economic performance at the national level. To test this notion, we surveyed 6723 participants from 36 countries. In line with predictions, propensity to believe conspiracy theories was negatively associated with perceptions of current and future national economic vitality. Furthermore, countries with higher GDP per capita tended to have lower belief in conspiracy theories. The data suggest that conspiracy beliefs are not just caused by intrapsychic factors but are also shaped by difficult economic circumstances for which distrust might have a rational basis.     

The Relation Between Norm Accessibility,Pornography Use,and Parental Mediation Among Emerging Adults

Widespread access to and use of pornography has led to concern about the potentially negative effects of exposure to pornography on emerging adults—its largest user group. Past research shows that salient social norms can influence subsequent behavior. This study, therefore, explored the relationship between salient pornography-related norms and pornography use among emerging adults, as well as the relationship between parental mediation of pornography during adolescence and emerging adults’ salient pornography-related norms. Results revealed that emerging adults are more likely to view pornography when they hold a salient belief (norm) that their peers both approve of viewing and regularly view pornography. The study also found that parents’ provision of rules about viewing pornography during adolescence may reduce future pornography use by instilling the salient belief that the parent disapproves of viewing pornography. These findings suggest that the effect of rules in the home about adolescents’ use of pornography may persist into emerging adulthood.     

Brain mapping in dysphonemic dyslexia: in resting and phonemic discrimination conditions.

Topographic mapping of EEG bands and alpha asymmetry were analyzed during resting conditions and an auditory phonemic discrimination task (APD) in carefully screened samples of 9.0- to 12-year-old control and dysphonemic-sequencing dyslexic children. The EEG was recorded over the entire scalp, with a linked ears reference. We found: (1) no differences between groups during resting conditions in any frequency band analyzed; (2) a left hemisphere alpha responsiveness in dyslexic children during the APD condition; and (3) a beta 2 decrease in the left posterior quadrant in dyslexics during the APD condition. We conclude that the lower alpha and beta 2 responsiveness may be due to a diminished cortical reactivity and may be related to intrinsic disorganization of the neural processors associated directly with the APD task demands, the alpha activity reflecting poor attention to an external stimuli source and the beta 2 decrease reflecting an unusual processing associated with the linguistic cognitive requirements.     

Fear,attachment and affiliation: The interaction of functional systems in 8- and 12-month-old infants

In this research fear of strangers has been analysed as it interacts with attachment and affiliation, and in relation to developmental level, in conditions most similar to the natural situations where encounters with unfamiliar persons take place. A total of 30 infants and their mothers participated. The children were divided into two groups (8-9 and 11-12 months). Each infant was approached by two females, who, in turn, produced either of two natural sequences. Our results allowed us to confirm the universality of fear and its coexistence and interaction with attachment and affiliation. As far as the role that developmental level plays, it was noted that in the 12-month-old infants fear reactions were more intense than in the younger ones. Furthermore, the attachment system was more activated in the older group in the intrusive episodes, but when the threatening nature of the situation decreased, attachment was activated less in the 12-month-old group. Another difference was related to control resources. While in the younger infants we observed a tendency to control their own emotional state, the 12-month-old infants tried to gain control over the stranger. These results were interpreted by considering the adaptative value of an increase with age of the capacity to evaluate a situation's threat value, of attachment security, and of behavioural resources permitting some control over the stranger's behaviour.
