Collectivize social support? Elements for reconsidering the social dimension in the study of social support

Psychological models of mental disorders play an important role in the explanation of psychological deterioration. Researchers from this area usually study several cognitive and behavioral variables to account for the onset and maintenance of depression. However, many authors have detected the need to include a "social dimension" in the explanation of deterioration. In this sense, social support has become a crucial aspect in the study of mental health, and the psychological literature on this topic has generated an intense debate about several facets of the positive impact of social networks on psychological well-being. In this article, the author defends that this increasing centrality of the concept has been accompanied by a psychological reductionism that is making the role of "social aspects" to explain psychological well-being more problematic. Implications of this reductionism are discussed, and an alternative proposal is made to overcome some theoretical and empirical problems related to social support research.     

ERPs studies of cognitive processing during sleep

In the last few decades, several works on cognitive processing during sleep have emerged. The study of cognitive processing with event related potentials (ERPs) during sleep is a topic of great interest, since ERPs allow the study of stimulation with passive paradigms (without conscious response or behavioural response), opening multiple research possibilities during different sleep phases. We review ERPs modulated by cognitive processes during sleep: N1, Mismatch Negativity (MMN), P2, P3, N400-like, N300-N550, among others. The review shows that there are different cognitive discriminations during sleep related to the frequency, intensity, duration, saliency, novelty, proportion of appearance, meaning, and even sentential integration of stimuli. The fascinating results of cognitive processing during sleep imply serious challenges for cognitive models. The studies of ERPs, together with techniques of neuroimaging, have demonstrated the existence of cognitive processing during sleep. A fundamental question to be considered is if these cognitive phenomena are similar to processing that occurs during wakefulness. Based on this question we discussed the existence of possible mechanisms associated with sleep, as well as the specific cognitive and neurophysiologic differences of wakefulness and sleep. Much knowledge is still required to even understand the conjunction of dramatic changes in cerebral dynamics and the occurrence of cognitive processes. We propose some insights based on ERPs research for further construction of theoretical models for integrating both cognitive processing and specific brain sleep dynamics.     

Semiorders and thresholds of utility discrimination: Solving the Scott–Suppes representability problem

We find an internal characterization of the so-called Scott–Suppes representability of a semiorder, defined as the existence of a numerical representation for a semiorder through a real-valued utility function and a positive constant threshold of discrimination.     

Cultural-Related, Contextual, and Asthma-Specific Risks Associated with Asthma Morbidity in Urban Children

The objective of this study was to examine associations between specific dimensions of the multi-dimensional cumulative risk index (CRI) and asthma morbidity in urban, school-aged children from African American, Latino and Non-Latino White backgrounds. An additional goal of the study was to identify the proportion of families that qualify for high-risk status on each dimension of the CRI by ethnic group. A total of 264 children with asthma, ages 7–15 (40% female; 76% ethnic minority) and their primary caregivers completed interview-based questionnaires assessing cultural, contextual, and asthma-specific risks that can impact asthma morbidity. Higher levels of asthma-related risks were associated with more functional morbidity for all groups of children, despite ethnic group background. Contextual and cultural risk dimensions contributed to more morbidity for African-American and Latino children. Analyses by Latino ethnic subgroup revealed that contextual and cultural risks are significantly related to more functional morbidity for Puerto Rican children compared to Dominican children. Findings suggest which type of risks may more meaningfully contribute to variations in asthma morbidity for children from specific ethnic groups. These results can inform culturally sensitive clinical interventions for urban children with asthma whose health outcomes lag far behind their non-Latino White counterparts.     

A comparison of individual and group equivalence-based instruction delivered via Canvas

Equivalence-based instruction (EBI) is an efficient method that has been used to teach various skills, including content in college courses. This study extended the literature on EBI in higher education by teaching 13 graduate students to identify features of functional analysis conditions and variations. Equivalence-based instruction methods were implemented using Canvas, an online learning management system. Participants completed pretests, experienced EBI individually and in small groups, and completed a posttest, all using the quiz feature in Canvas. The EBI modules increased students' posttest scores relative to pretest scores by 36%, on average, and there was a slight increase in correct responding in the group relative to the individual teaching condition. Furthermore, responses to social-validity surveys indicated that EBI was acceptable to most students; however, students' preferences for group and individual EBI varied.     

Relationship between impulsiveness and deviant behavior among adolescents in the classroom: age and sex differences

To assess the relationship between impulsiveness and deviant behavior among 103 adolescents, taking into account their sociodemographic characteristics, the Barratt Impulsiveness Scale and a self-assessment measure with regard to disruptive and deviant behaviors which had occurred in the last 90 days were used. The results show that impulsiveness and disruptive behavior in the classroom were related to deviant behavior outside of the classroom. Therefore, age and sex explained the relationship between impulsiveness and behavior. The older adolescents and the girls showed less disruptive behaviors than the younger participants and the boys; both variables showed an interactive effect on disruptive behavior. The age at which sexual activity commenced and the number of sexual partners were also significantly related to impulsiveness and disruptive and deviant behavior. Similarly, impulsiveness was shown to have a significant relationship with disruptive and deviant behavior, and disruptive behavior was shown to have a significant relationship with deviant behavior.     

Visual recognition memory enhancement in children through differential outcomes

Objective

The use of differential outcomes has been shown to enhance discriminative learning and face recognition in children and adults. In this study, we further investigated whether the differential outcome procedure (DOP) would also be effective in improving recognition memory for a wide range of stimuli with varying visual complexity (familiar objects, abstract stimuli, and complex scenes) in 5- and 7-year-old children.

Method

Participants viewed a sample stimulus and, after a short (5 s) or a long (15 s) delay, they had to identify the previously seen stimulus among four choice alternatives. In the differential outcomes condition, each sample stimulus was paired with a specific outcome; whereas in the non-differential conditions outcomes were administered randomly. In Experiment 2, we replicated Experiment 1 but in addition we asked participants to perform an articulatory suppression task to prevent verbal rehearsal.

Results

Children showed a greater overall visual delayed recognition when differential outcomes were arranged in both experiments. The type of stimulus being used modulated this effect; a beneficial effect of the differential outcomes training was evident with abstract objects in Experiment 1 and with both, abstract objects and scenes in Experiment 2.

ADOLESCENTS' SEXUAL INFERENCES ABOUT GIRLS WHO CONSUME ALCOHOL

The purpose of this study was to document whether adolescents make inferences regarding male and female vignette characters in terms of the characters' sexuality, social skills, impairment, and aggressiveness when the characters consume alcohol. A Web-based survey of 1,691 middle and high school students (grades 6–11) from diverse socioeconomic and ethnic backgrounds was conducted. The Dating Vignette and Subjective Perception Form ( George, Gournic, & McAfee, 1988 ) were modified for use with an adolescent sample and embedded within the Web-based survey. There were significant interaction effects between the male and female characters' alcohol consumption in terms of the respondents' perception of the female character for all of the subscales examined (i.e., sexual disinhibition, social skills, impairment, and aggressiveness). In contrast, there were no significant interactions between the characters' drinking and the respondents' perception of the male character. Collectively, these findings suggest that adolescents' perceptions of girls are based not only on the girls' own drinking behaviors, but also their male partners' drinking behaviors.
