A cross-modal effect of noise: the disappearance of the alarm reaction of a freshwater fish

Anthropogenic noise pollution is recognized as a major global stressor of animals. While many studies have assessed the unimodal impacts of noise pollution with a focus on intraspecific acoustic communication, little is known about noise pollution on the perception of visual and chemical information. The ‘distracted prey hypothesis’ posits that processing noise interferes with processing other information in the brain. Here, we found evidence for such a cross-modal effect of noise on the antipredator behaviour of a freshwater prey fish, the fathead minnow, Pimephales promelas. In laboratory trials, exposure to noise from a motorboat caused the total absence of the classical fright reaction of minnows to conspecific alarm cues, whereas an ambient noise control had no such impact. In natural habitats, the impairment of such antipredator behaviour due to noise pollution could have major fitness consequences. We discuss how our findings translate to animal ecology and the need for future studies that target specific management decisions regarding noise pollution.     

Predicting Negotiation Performance from Personality Traits: A field Study across Multiple Occupations

Based on decades-old reviews, many negotiation researchers have expressed doubts about the effect of personality on negotiation outcomes. More recent reviews have found significant associations between traits and outcome measures. Existing research has primarily used laboratory experiments; field studies are rare. In this study, we aim to fill that important gap. Traits measured using the Hogan Personality Inventory were correlated with supervisor ratings of negotiation performance across three occupations: marketing managers, lawyers, and construction supervisors. Ambition and likability independently predicted greater negotiation performance. Results generalized across these three samples with evidence for an interaction effect in the lawyer sample. For attorneys, greater ambition was not additionally helpful for those who were relatively more likable. Results establish the importance of negotiation effectiveness as a distinct component of overall job performance. Practical implications are considered in terms of division of labor, person–job fit, and the state-trait distinction.     

Is Scripture the origin of the Halakhah?

Scripture, in particular the Pentateuch, forms the natural starting point for any inquiry into origins in Judaism. The question answered here derives from a simple fact: the Pentateuch is privileged within the Rabbinic system, which links as much of the Halakhah to the Pentateuchal law codes as it possibly can. So it is quite natural to treat Scripture as the base-line and the Halakhic category-formations as the variable, in seeking the origin of the system. But what happens when we treat the system as the base-line and Scripture as the variable? Then we see that the Halakhic system viewed as a coherent statement does not originate in Scripture. Scripture is not the origin of the Halakhah. Why not? Because of this paradox: Scripture is necessary for the Halakhic system. But Scripture is insufficient for the Halakhic system. The Halakhic system is necessary for Scripture. The Halakhic system is sufficient without Scripture. It requires only Scripture's facts - and these on their own form no system.     

40,000 memories in young teenagers: Psychometric properties of the Autobiographical Memory Test in a UK cohort study

Although the Autobiographical Memory Test (AMT) is widely used its psychometric properties have rarely been investigated. This paper utilises data gathered from a 10-item written version of the AMT, completed by 5792 adolescents participating in the Avon Longitudinal Study of Parents and Children, to examine the psychometric properties of the measure. The results show that the scale derived from responses to the AMT operates well over a wide range of scores, consistent with the aim of deriving a continuous measure of over-general memory. There was strong evidence of group differences in terms of gender, low negative mood, and IQ, and these were in agreement when comparing an item response theory (IRT) approach with that based on a sum score. One advantage of the IRT model is the ability to assess and consequently allow for differential item functioning. This additional analysis showed evidence of response bias for both gender and mood, resulting in attenuation in the mean differences in AMT across these groups. Implications of the findings for the use of the AMT measure in different samples are discussed.     

Feasibility and validity of the structured attention module among economically disadvantaged preschool-age children

Rooted in the theory of attention put forth by Mirsky, Anthony, Duncan, Ahearn, and Kellam (1991), the Structured Attention Module (SAM) is a developmentally sensitive, computer-based performance task designed specifically to assess sustained selective attention among 3- to 6-year-old children. The current study addressed the feasibility and validity of the SAM among 64 economically disadvantaged preschool-age children (mean age = 58 months; 55% female); a population known to be at risk for attention problems and adverse math performance outcomes. Feasibility was demonstrated by high completion rates and strong associations between SAM performance and age. Principal Factor Analysis with rotation produced robust support for a three-factor model (Accuracy, Speed, and Endurance) of SAM performance, which largely corresponded with existing theorized models of selective and sustained attention. Construct validity was evidenced by positive correlations between SAM Composite scores and all three SAM factors and IQ, and between SAM Accuracy and sequential memory. Value-added predictive validity was not confirmed through main effects of SAM on math performance above and beyond age and IQ; however, significant interactions by child sex were observed: Accuracy and Endurance both interacted with child sex to predict math performance. In both cases, the SAM factors predicted math performance more strongly for girls than for boys. There were no overall sex differences in SAM performance. In sum, the current findings suggest that interindividual variation in sustained selective attention, and potentially other aspects of attention and executive function, among young, high-risk children can be captured validly with developmentally sensitive measures.     

The Relationship Between Marital Satisfaction,Marital Stability,Nuclear Family Triangulation,and Childhood Depression

This study was to examine the effect of triangulation on depression in children. Clinical samples and nonclinical samples were taken from Utah and Illinois. Families were assessed for marital satisfaction and stability, family triangulation, and children's depression levels by the Marital Adjustment Test, Marital Status Inventory, Nuclear Family Triangulation, and Children's Depression Inventory. Results showed children's depressive symptoms to be most strongly linked to fathers' level of marital satisfaction, marital stability, and perceived family triangulation. Mothers' variables did not affect children's depressive symptoms .

Costs of Treating Conduct Disordered Medicaid Youth with and without Family Therapy

This longitudinal, retrospective study investigated the healthcare costs of youth treated for conduct disorder in the Kansas Medicaid system. Along with a comprehensive range of services, youth received in-office individual therapy, in-office family therapy, or in-home family therapy. Data was available for 3753 youth. Overall, 3086 youth received care that included individual therapy (and no family therapy), 503 received in-home family therapy and 164 others received in-office family therapy. Healthcare costs for a period of two and one half years after therapy were available for analysis. The average cost of healthcare for youth receiving no family therapy was $16, 260. For those receiving in-office family therapy, the average cost was $11,116. Youth who received in-office family therapy received $5,144 (32%) less care on average than those receiving only individual therapy. Those who received in-home family therapy averaged $1,622 over the follow-up the period. Those who received in-home family therapy were least expensive of all, averaging at least 85% less than any form of in-office therapy. There does not appear to be an increase in the healthcare cost when family therapy is included in treatment.     

Tracking Marital Adjustment,Hostility, and Physical Functioning Across Time in a Therapy Population: A Biopsychosocial Model

In this study we sought to explore the biopsychosocial connections between relational adjustment, hostility, and physical functioning of individuals who attended psychotherapy. Assessments were given at therapy intake, 6 months post intake, and 12 months after therapy intake. Path analyses between relational adjustment, hostility, and physical functioning revealed a good fit to the data. Results indicated that therapy may interrupt the relationship between hostility at intake and later marital satisfaction. Individuals’ ability to function physically day to day at 6 months post therapy intake contributed to increased marital adjustment 12 months after intake. Clinical implications are discussed.     

Multiple caregivers' touch interactions with young children among the Bofi foragers in Central Africa

The current study examined the use of three types of touch (caregiving, active social-affectionate, and passive social-affectionate) by caregivers with young children among the Bofi foragers, a seminomadic group of hunter-gatherers in Central Africa. With the purpose of providing a more holistic view of touch interactions in early childhood, compared to extant Western mother-centric views, this study documents stylistic touch patterns used by multiple caregivers (mother, father, adult relatives, and juvenile relatives) with Bofi forager children. Thirty-five Bofi forager children, between 18 and 59 months of age, and their various caregivers were naturalistically observed over 12 daylight hours using a focal child observational technique. Frequencies of each type of touch and the rank order of types of touch that children received were compared between caregivers and examined by child age and gender. Even though nonmaternal caregivers showed high physical involvement with children, mothers exemplified the highest level of involvement. Overall, passive social-affectionate touch was utilized the most by all types of caregivers. Mothers used more caregiving touch, and fathers and adult relatives had similar frequencies of caregiving touch and active social-affectionate touch. In contrast, juvenile relatives showed more active social-affectionate touch with focal children. This study highlights the importance of examining multiple caregivers and physical interactions when studying early childhood experiences. Furthermore, by focusing on multiple caregivers and multiple types of touch, this study provides a more thorough characterization of the touch experiences of young children than previous studies of touch. Finally, the current study exemplifies the value of considering non-Western populations when investigating touch interactions.
