Emotion and perception of one's own actions--a comment on Wilke, Synofzik and Lindner

Wilke et al. (2012) make significant headway in gaining a better understanding of the influence affect cues may have on action perception and judgement. In our view their account also brings up a row of important questions demanding further research. This concerns (a) the role of conceptual and non-conceptual content and (b) the different effects emotions of the same valence may play in the perception and judgement of action.     

Children’s Acceptance of Others with Disability: The Influence of a Disability-Simulation Program

Elementary school is a transitional and impressionable period for any child. In inclusive classroom settings, children with disabilities may experience the challenges of acceptance and integration into peer relationships. The experience of children with disabilities in such classrooms can be positive if their classmates are accepting and open. One way to encourage these attitudes is by increasing awareness through disability-simulation. This study evaluates an existing school program, whose goal is to increase acceptance of others with disability. We surveyed students to assess the influence of the program. An adapted acceptance scale was distributed to students before and after participation in the program. Our hypothesis was that student acceptance would increase after participating in the program. Additionally, we hypothesized that physical, visual, and auditory disabilities would be easier for students to understand, making acceptance scores for these disabilities higher than those for a learning disability. We report changes in acceptance using group means. Our results reveal that post-survey responses showed higher acceptance than pre-survey responses, especially for auditory disabilities. Other significant findings include differences in attitudes between the two schools and differences based on prior experience with someone with a disability. By evaluating the effectiveness of this type of program (whose efficacy has been controversial in the literature), this study can provide teachers, administrators, genetic counselors, and parents with a better idea of how to address children’s attitudes towards peers. In our study, the effectiveness of promoting understanding through disability-simulation has proven its worth to improve children’s acceptance.     

Psychometric properties of the Five Facets Mindfulness Questionnaire (FFMQ) in a meditating and a non-meditating sample

The factor structure, internal consistency, construct validity, and predictive validity of the Dutch version of the Five Facet Mindfulness Questionnaire (FFMQ-NL) were studied in a sample of meditators (n = 288) and nonmeditators (n = 451). A five-factor structure was demonstrated in both samples, and the FFMQ-NL and its subscales were shown to have good internal consistencies. Meditators scored higher on all facets of the FFMQ-NL than the participants in the nonmeditating sample. For both samples, expected negative correlations between most mindfulness facets (all except for the Observing facet) and the constructs of alexithymia, thought suppression, rumination, worry, and dissociation were found. The Observing facet of the FFMQ-NL showed an unexpected positive correlation with thought suppression in the nonmeditating sample. Furthermore, as expected, mindfulness facets were negatively related to psychological symptoms, and all mindfulness facets except for Observing and Describing significantly predicted psychological symptoms. Overall, the Dutch FFMQ demonstrated favorable psychometric properties, commensurate with its (original) English language version.     

A mixed model approach to meta-analysis of diagnostic studies with binary test outcome

We propose 2 related models for the meta-analysis of diagnostic tests. Both models are based on the bivariate normal distribution for transformed sensitivities and false-positive rates. Instead of using the logit as a transformation for these proportions, we employ the tα family of transformations that contains the log, logit, and (approximately) the complementary log. A likelihood ratio test for the cutoff value problem is developed, and summary receiver operating characteristic (SROC) curves are discussed. Worked examples showcase the methodology. We compare the models to the hierarchical SROC model, which in contrast employs a logit transformation. Data from various meta-analyses are reanalyzed, and the reanalysis indicates a better performance of the models based on the tα transformation.

The influence of control and related variables on commuting stress

Existing research on commuting stress has shown that it is affected by variables such as control, predictability, the duration of the commute and impedance. The present study investigates the impact of several factors on the stress that commuters experience and clarifies possible relations between variables. For the purpose of this study, an online questionnaire was completed by 363 commuters of the Vienna region. The relative strength of the relationship between predictors and commuting stress was determined by multiple regression analysis. Results suggest that control is the most powerful predictor of commuting stress, followed by the duration of the commute, predictability and impedance. Control significantly interacts with the duration of the commute and predictability. Based on these findings a research model is proposed, clearly depicting the moderating impact of the duration of the commute and incorporating a clear distinction between predictability and control.     

Bicycle helmets – A case of risk compensation?

Several studies have shown that bicycle helmets have the potential of reducing injuries from accidents. Yet, no studies have found good evidence of an injury reducing effect in countries that have introduced bicycle helmet legislation. Two of the most promising explanations for why helmet laws do not work as intended are risk compensation and shifts in the cycle population as a response to the law.The present article investigates whether the lack of effect of helmet wearing laws is due to risk compensation mechanisms or population shifts (i.e. discouraging cyclists with the lowest accident risk, and thereby increasing the overall average risk per cyclist). A random sample of 1504 bicycle owners in Norway responded to a questionnaire on among other things helmet use, bicycle equipment use, accident involvement, cycling behaviour and risk perception. Data were analysed by using structural equation model (SEM). The results show that the cyclist population in Norway can be divided into two sub-populations: one speed-happy group that cycle fast and have lots of cycle equipment including helmets, and one traditional kind of cyclist without much equipment, cycling slowly. With all the limitations that have to be placed on a cross sectional study such as this, the results indicate that at least part of the reason why helmet laws do not appear to be beneficial is that they disproportionately discourage the safest cyclists.     

Associative memory or algorithmic search: a comparative study on learning strategies of bats and shrews

Two common strategies for successful foraging are learning to associate specific sensory cues with patches of prey ("associative learning") and using set decision-making rules to systematically scan for prey ("algorithmic search"). We investigated whether an animal's life history affects which of these two foraging strategies it is likely to use. Natterer's bats (Myotis nattereri) have slow life-history traits and we predicted they would be more likely to use associative learning. Common shrews (Sorex araneus) have fast life-history traits and we predicted that they would rely more heavily on routine-based search. Apart from their marked differences in life-history traits, these two mammals are similar in body size, brain weight, habitat, and diet. We assessed foraging strategy, associative learning ability, and retention time with a four-arm maze; one arm contained a food reward and was marked with four sensory stimuli. Bats and shrews differed significantly in their foraging strategies. Most bats learned to associate the sensory stimuli with the reward and remembered this association over time. Most shrews searched the maze using consistent decision-making rules, but did not learn or remember the association. We discuss these results in terms of life-history traits and other key differences between these species. Our results suggest a link between an animal's life-history strategy and its use of associative learning.     

Psychometric properties and concurrent validity of two exercise addiction measures: A population wide study

ObjectivesThe existence of exercise addiction has been examined in numerous studies. However, none of the measures developed for exercise addiction assessment have been validated on representative samples. Furthermore, estimates of exercise addiction prevalence in the general population are not available. The objective of the present study was to validate the Exercise Addiction Inventory (EAI; Terry, Szabo, & Griffiths, 2004), and the Exercise Dependence Scale (EDS; Hausenblas & Downs, 2002b), and to estimate the prevalence of exercise addiction in general population.DesignExercise addiction was assessed within the framework of the National Survey on Addiction Problems in Hungary (NSAPH), a national representative study for the population aged 18–64 years (N = 2710).Method474 people in the sample (57% males; mean age 33.2 years) who reported to exercise at least once a week were asked to complete the two questionnaires (EAI, EDS).ResultsConfirmatory Factor Analysis (CFA) indicated good fit both in the case of EAI (CFI = 0.971; TLI = 0.952; RMSEA = 0.052) and EDS (CFI = 0.938; TLI = 0.922; RMSEA = 0.049); and confirmed the factor structure of the two scales. The correlation between the two measures was high (r = 0.79). Results showed that 6.2% (EDS) and 10.1% (EAI) of the population were characterized as nondependent-symptomatic exercisers, while the proportion of the at-risk exercisers were 0.3% and 0.5%, respectively.ConclusionsBoth EAI and EDS proved to be a reliable assessment tool for exercise addiction, a phenomenon that is present in the 0.3–0.5% of the adult general population.     

Mothers' and Fathers' Internal State Language with Their Young Children: An Examination of Gender Differences During an Emotions Task

The current study examined gender differences in mothers' and fathers' internal state language (ISL), children's use of ISL, and whether ISL was related to parents' ratings of the children's social skills. Fifty‐seven (28 boys, 29 girls) toddler/preschool children (M age = 32.5 months, SD = 5.38 months) were observed separately with their mothers and fathers in their homes while they discussed pictures of children's facial expressions of emotions. Parents completed a questionnaire concerning their child's social–emotional behaviours (i.e. BASC‐2). Parents used more ISL with sons compared with daughters, and sons used more ISL with mothers than with fathers. No overall differences were found between mothers' and fathers' ISL. Children's social skills as rated by mothers were predicted by mothers' ISL comments, whereas children's social skills as rated by fathers were predicted by children's age and fathers' ISL clarifications. Implications and limitations of the study are discussed. Copyright © 2012 John Wiley & Sons, Ltd.
