Exposure to a specific prompt topography predicts its relative efficiency when teaching intraverbal behavior to children with autism spectrum disorder

Comparisons of the relative efficiency of different prompt topographies (visual or auditory), when teaching intraverbal behavior to children with disabilities, have yielded idiosyncratic results. Recent research has shown that previous exposure to a specific prompt type may affect its efficiency when teaching intraverbal behavior to preschool children. The current study was an attempt to replicate these results with 3 children diagnosed with autism spectrum disorder. For all participants, increased exposure to one prompt topography was sufficient to make it relatively more efficient as measured by number of trials to criterion. These results suggest that previous history with a prompt type may predict its efficiency.     

Simple discrimination training with differential responses to establish functional and equivalence classes with preschool children

The present study assessed whether simple discrimination training with differential responses would produce functional and equivalence classes with preschool children. In Experiment 1, we exposed 10 children to simple successive discrimination training in which they had to press different buttons (selection‐based responses). Response 1 (R1) was reinforced only in the presence of A1, B1, or C1, and Response 2 (R2) was reinforced only in the presence of A2, B2, or C2. We assessed the formation of functional classes by training new selection responses in the presence of one member of each class (A1‐R3, A2‐R4) and testing to see if these responses would occur in the presence of other members. Eight children responded consistently with functional class formation. Four of these eight children also responded consistently with the formation of equivalence classes. Experiment 2 investigated whether differential motor responses (i.e., gestures) would improve equivalence class yields. Three of six children showed both functional and equivalence class formation. In general, the results indicate that the simple discrimination procedure with differential responses yielded functional and equivalence class formation.     

Attachment and coparenting representations in men during the transition to parenthood

Coparenting is based on parents’ representations of themselves as coparents. Attachment theory can be a useful framework to understand the way that different coparenting representations are developed during the transition to parenthood. This study aimed to analyze the association between men's attachment and coparenting representations at the first trimester of pregnancy and from the first trimester of pregnancy to 6 months’ postpartum. A sample of 86 men was recruited and completed self-report measures of attachment and coparenting representations at the first and third trimester of pregnancy and at 1 and 6 months’ postpartum. At the first trimester of pregnancy, higher attachment avoidance was associated with higher lack of coparenting support. From the first trimester of pregnancy to 6 months’ postpartum, higher attachment avoidance was associated with (a) a steeper increase on lack of coparenting support, (b) an increase on coparenting conflict (while low attachment avoidance was associated with a decrease), and (c) a lower decrease on coparenting disagreement. This study may contribute to coparenting research by showing new evidence on attachment theory as a useful framework to understand how different coparenting representations are developed in men during the transition to parenthood.     

Temperature increases in preterm infants during massage therapy

Temperature was assessed in 72 preterm infants randomly assigned to a control or a massage therapy group. A greater increase in temperature was noted for preterm infants receiving massage therapy versus a control group, even though the incubator portholes remained open during the 15 min massage therapy session but not for the control group over an equivalent time period.     

Short-term storage and mental speed account for the relationship between working memory and fluid intelligence

Here, we explore the role of short-term storage, mental speed, processing efficiency, and controlled attention to account for the relationship between working memory and fluid intelligence. Ninety-six secondary school students were assessed by several tests and tasks to tap these psychological constructs. Specifically, each construct was measured by two tests or tasks from different content domains (verbal-numerical and spatial). The findings show that short-term storage and, to a lesser degree, mental speed, account for the relationship between working memory and fluid intelligence. Further, processing efficiency and controlled attention do not play a significant role.     

Drug consumption and perception among Latin American immigrants

The aim of this study is to obtain information about drug consumption, leisure activities and knowledge of community services among Spanish-speaking immigrants to prevent drug abuse in this population. Quantitative methodology was used. The field work of this study has two phases: in the first stage (2003), a survey of social perception of drugs was administered to 147 subjects. During the second stage (2004), 610 surveys were administered. Data were analysed by bivariate analysis. Usual consumption of alcohol was 40.1%, usual consumption of tobacco was 31.3%, and usual consumption of cannabis was 3.4%. Drug users considered that the main reason for drug consumption was "to have fun" (p<.03). There is a relationship between leisure time and drug use. Family plays an important role in drug abuse prevention and preventive drug abuse programs must be adapted to this population.     

Development of the brief Spanish Cocaine Craving Questionnaire-General

Combining two different samples of cocaine users (N = 183), we tested the factor structure of a brief (12-item), Spanish version of the Cocaine Craving Questionnaire-General using confirmatory factor analysis. The four-factor model provided excellent fit to the measure. Moreover, the measure significantly differentiated between recent cocaine users and abstainers, as well as between participants with different levels of severity of drug-use history. Factor 1 expresses highly intense and overwhelming desires, Factor 2 expresses lack of self-control over cocaine use, Factor 3 items express lack of positive reinforcement expectancies, and Factor 4 expresses stimulating expectancies for cocaine use. The results revealed the validity of the CCQ-General brief as an instrument to assess cocaine craving in Spanish and supported the conceptualization of cocaine craving as a multifaceted construct.     

Body-image and obesity in adolescence: a comparative study of social-demographic, psychological, and behavioral aspects

In current society, body and beauty's cult emerge as one of the main factors of adolescence. That leads adolescents to be dissatisfied with their own appearance, to psychological maladjustment, and nutritional disorders. This quantitative, exploratory, and cross-sectional research evaluates how adolescents perceive their weight and the prevalence of obesity in a sample of adolescents from the district of Viseu (Portugal). It also attempted to compare the relation of body-image and obesity with sociodemographic (school, sex, age, socioeconomic status, family functioning), psychological (self-concept, depression, school success) and behavioral aspects (physical inactivity). After data analyses, it was verified that the prevalence of obesity was 8.8% but 12.7% considered themselves obese. These adolescents had higher physical inactivity, poorer family functioning, a lower self-concept, and a higher depression index. The really obese adolescents were older and had poorer academic results. Obesity was higher in boys, but girls perceived themselves more as being obese. In conclusion, it is essential to evaluate weight perception in addition to body mass index (BMI), because the main problem could be related not only to being obese, but also to the perception of having a higher than ideal weight.     

Types of media violence and degree of acceptance in under‐18s

It is an established fact that almost every TV channel offers a high level of violent content. The object of this study is to check the degree of acceptance of this media violence in under‐18s. We will also check what cognitive and emotional effects the viewing of different types of violence has. A sample of 203 subjects aged 13 years from Madrid, Spain, viewed a clip from different films. Before and after the film, data were collected about their opinion on violence. Three viewing conditions were established according to the degree and type of violence shown and based on Berkowitz [(1996): Desclée De Brouwer]: action without violence, socially justified violence, and socially unjustified violence. Several ANOVAs were carried out revealing that violence is better valued and more attractive after watching the film sequences than before the showing. Aggr.

Differential sucking by neonates of depressed versus non-depressed mothers

Forty-two neonates (M = 39-h old) of depressed and non-depressed mothers sucked on cold (50 °F) and warm (78 °F) nipples on alternating trials. Half the infants received the cold nipple on the first of the eight trials (20 s each) and the other half received the warm nipple first. Neonates of depressed mothers sucked twice as much as neonates of non-depressed mothers, suggesting arousal dysregulation, overactivity or greater hedonic behavior in the newborns of depressed mothers. Although the newborns did not show a preference for cold or warm nipples, a temperature order effect revealed that neonates who received the cold nipple on the first trial sucked significantly more on trials 2–8 than those who received the warm nipple on the first trial, suggesting that an initially cold nipple might elicit greater sucking. More research is needed on maternal mood effects and temperature of objects to determine how these factors affect neonatal sucking behaviors.
