Relationship between learning environment characteristics and academic engagement

The relationship between learning environment characteristics and academic engagement of 777 Grade 6 children located in 41 learning environments was explored. Questionnaires were used to tap learning environment perceptions of children, their academic engagement, and their ethnic-cultural background. The basis of the learning environment questionnaire was the International System for Teacher Observation and Feedback (ISTOF). Factor analysis indicated three factors: the teacher as a helpful and good instructor (having good instructional skills, clear instruction), the teacher as promoter of active learning and differentiation, and the teacher as manager and organizer of classroom activities. Multilevel analysis indicated that about 12% of the differences in engagement between children was related to the learning environment. All the mentioned learning environment characteristics mattered, but the teacher as a helpful, good instructor was most important followed by the teacher as promoter of active learning and differentiation.     

Evidenzbasierte Psychotherapie der Panikst?rung mit und ohne Agoraphobie

From the evidence reported in the recent guidelines [Heinrichs et al. (2009) Evidenzbasierte Leitlinie zur Psychotherapie der Panikst?rung mit und ohne Agoraphobie. Hogrefe, G?ttingen] the following conclusions can be drawn with respect to the treatment of panic disorder with or without agoraphobia, as well as for agoraphobia without panic disorder:

1. Every psychotherapy should be preceded by suitable diagnostics and a case formulation.
2. The effectiveness of every psychotherapy should be evaluated with well established measures.
3. For the treatment of panic disorder without agoraphobia, cognitive behavioral treatment (CBT) and applied relaxation have been shown to be effective (evidence grade 1).
4. For panic disorder with agoraphobia, CBT, combination treatment (CBT plus medication), as well as panic-focused psychodynamic psychotherapy in the outpatient setting have shown short-term effectiveness (evidence grade 1). Longer lasting effects have been documented for CBT (evidence grade 1).
5. For agoraphobia without panic disorder, CBT with a focus on situational exposure can be recommended (evidence grade 1).

     

Future orientation, impulsivity, and problem behaviors: a longitudinal moderation model

In the current study, based on a sample of 1,873 adolescents between 11.4 and 20.9 years of age from the first 3 waves of the National Longitudinal Study of Adolescent Health, we investigated the longitudinal effects of future orientation on levels of and developmental changes in problem behaviors, while controlling for the effects by impulsivity; we also tested the moderating effects by future orientation on the impulsivity-problem behaviors link over time. Additionally, we examined future orientation operationalized by items measuring education, marriage, and life domains. Findings based on growth curve analyses provided evidence of longitudinal effects by education and life future orientation on both levels of and developmental changes in problem behaviors; the effect of marriage future orientation was not significant for either test. In addition, only life future orientation moderated the effect by impulsivity on levels of problem behaviors over time. More specifically, impulsivity had a weaker effect on levels of problem behaviors over time for adolescents who reported higher levels of life future orientation.     

Using personality and cognitive ability to predict academic achievement in a young adult sample

This study examined the relationship between cognitive ability, personality, and academic achievement in post-secondary students, using latent variable models. Testing both simple and complex relationships, we found that cognitive ability and personality predicted reading achievement independently, but that they interact when predicting math achievement - at least in the Conscientiousness and Openness to Experience domains.     

An inkblot for sexual preference: a semantic variant of the Affect Misattribution Procedure

A newly developed Semantic Misattribution Procedure (SMP), a semantic variant of the Affect Misattribution Procedure (AMP), was used in three studies as an indirect measure of sexual interest. Using a known-group approach, homosexual men (Studies 1 and 2), heterosexual men (Studies 1 to 3) and heterosexual women (Study 3) were asked to guess the meaning of briefly presented Chinese ideographs as "sexual" or "not sexual". The ideographs were preceded by briefly presented primes depicting male and female individuals of varying sexual maturity. As hypothesised, the frequency of "sexual" responses increased after priming with pictures of individuals of the preferred sex and increasing sexual maturation. The SMP showed satisfactory reliability and convergent validity as indicated by correlations with direct and two indirect measures of sexual interest. In two further studies, the hypothesised pattern was replicated whereas a standard AMP with the identical prime stimuli did not produce this result. The potential usefulness of semantic variants of the AMP is discussed.     

A policy maker’s dilemma: Preventing terrorism or preventing blame

Although anti-terrorism policy should be based on a normative treatment of risk that incorporates likelihoods of attack, policy makers’ anti-terror decisions may be influenced by the blame they expect from failing to prevent attacks. We show that people’s anti-terror budget priorities before a perceived attack and blame judgments after a perceived attack are associated with the attack’s severity and how upsetting it is but largely independent of its likelihood. We also show that anti-terror budget priorities are influenced by directly highlighting the likelihood of the attack, but because of outcome biases, highlighting the attack’s prior likelihood has no influence on judgments of blame, severity, or emotion after an attack is perceived to have occurred. Thus, because of accountability effects, we propose policy makers face a dilemma: prevent terrorism using normative methods that incorporate the likelihood of attack or prevent blame by preventing terrorist attacks the public find most blameworthy.     

External Validation of Bifactor Model of ADHD: Explaining Heterogeneity in Psychiatric Comorbidity,Cognitive Control,and Personality Trait Profiles Within DSM-IV ADHD

The current paper provides external validation of the bifactor model of ADHD by examining associations between ADHD latent factor/profile scores and external validation indices. 548 children (321 boys; 302 with ADHD), 6 to 18 years old, recruited from the community participated in a comprehensive diagnostic procedure. Mothers completed the Child Behavior Checklist, Early Adolescent Temperament Questionnaire, and California Q-Sort. Children completed the Stop and Trail-Making Task. Specific inattention was associated with depression/withdrawal, slower cognitive task performance, introversion, agreeableness, and high reactive control; specific hyperactivity-impulsivity was associated with rule-breaking/aggressive behavior, social problems, errors during set-shifting, extraversion, disagreeableness, and low reactive control. It is concluded that the bifactor model provides better explanation of heterogeneity within ADHD than DSM-IV ADHD symptom counts or subtypes.     

The big none: No evidence for a general factor of personality in chimpanzees, orangutans, or rhesus macaques

We examined whether a general factor of personality (GFP) was present in chimpanzees, orangutans, or rhesus macaques. We used confirmatory factor analysis (CFA) to model correlations among first-order factors as arising from a GFP. We then conducted principal axis factor analyses (PFA) of the first-order factors to extract a single higher-order factor and then to extract two oblique higher-order factors. The CFA model fit was poor for chimpanzees and orangutans, but not rhesus macaques. The single higher-order factors extracted via PFA did not resemble the GFP in all three species. The oblique higher-order factors extracted via PFA were only weakly correlated in all three species. These results do not support the existence of a GFP in nonhuman primates.     

Habitual computer game playing at night is related to depressive symptoms

This study investigated whether the amount and circadian time of habitual computer game playing were related to depressive symptoms in adolescents and young adults. We expected that habitual late playing relates to more depressive symptoms beyond the effect of the total time of computer game playing as playing at night may involve short, irregular, and disturbed sleep as well as misalignment of the circadian rhythm. 646 adolescents and young adults (ages 13–30; 90.9% males) who play the internet role-playing game World of Warcraft completed an online questionnaire. Habitual computer game playing between 10 pm and 6 am was related to an increased risk of high depression scores independent of the total amount of playing. Adolescents (ages 13–17 years) were most vulnerable when habitually playing during early night (i.e., 10–12 pm), while emergent adults (ages 18–22 years) showed more vulnerability when habitually playing late at night (i.e., after 2 am). The effect was partly mediated by daytime sleepiness but not by sleep loss or insomnia problems.
