Development and initial validation of the Brief Adolescent Life Event Scale (BALES)

We report initial validity analyses of the Brief Adolescent Life Event Scale (BALES). This instrument addresses negative and positive events pertinent to the well being of adolescent boys and girls, and is designed for use in studies utilizing an extended research protocol. Selection of items was guided by emerging perspectives on positive psychology , action theory , and personality vulnerability , as well as by new developments in statistical modeling theory. The 36 items of the scale tap negative and positive events, each of which addresses interpersonal and achievement life domains. Using a large sample of early-adolescents ( N = 895), we confirmed the hypothesized structure that includes four domain-level latent factors (i.e., negative interpersonal events, negative achievement events, positive interpersonal events, positive achievement events), and two overarching factors (negative events and positive events). Indices of positive and negative events predicted adolescent depressive symptoms in expected ways, and positive events buffered the effect of negative events on depressive symptoms. These findings encourage an informed use of the BALES and highlight considerations involved in the development of brief measures of stress and coping processes.     

Negative cognitive emotion regulation as a predictor of adolescent heart rate variability and entropy under social stress

ABSTRACT

Background and Objectives: Negative cognitive emotion regulation (ER) strategies are particularly important within the framework of anxiety problems amongst youths and how they cope with stressful events. The aim of this study was to examine the associations between both negative and positive ER style and cardiac regulation under stressful conditions.

Design: Eighty-nine adolescents (M?=?13.31 years, SD?=?0.68, 44.94% girls) were exposed to a socially relevant stress induction protocol.

Methods: Participants’ emotion regulation strategies were assessed and their cardiac function was recorded.

Results: A negative ER style predicted heart rate (HR) entropy at the stressful stage after controlling for anxiety scores. In addition, heart rate variability reactivity and recovery and HR entropy recovery were larger (p?<?.05) in the low negative ER style group (n?=?16) than in the high negative ER style group (n?=?23).

Conclusions: Results suggest that individuals with a highly negative ER style have diminished autonomic flexibility.     

Relationship between heart rate variability and cognitive function during threat of shock

Abstract

The aim of the present study was to investigate the relationship between resting heart rate variability (HRV) and cognitive functions during threat of shock. A Continuous Performance Task and a Working Memory Task were used to measure cognitive functions. Sixty-five male participants from the Royal Norwegian Navy participated. HRV was measured during baseline, test conditions and recovery. Participants were randomly assigned into non-threat and threat groups. Based on the median split of the high frequency (HF) spectral power, groups were divided into two additional groups. Overall, the high HRV participants showed superior performance on cognitive tasks independent of non-threat or threat conditions. During threat condition the low HRV group showed improved performance. Thus, individuals with high HRV were more stress tolerant and resilient in the face of environmental changes. The results from the study might have implications with regard to performance in operational settings, but also for other fields of psychological research such as individual differences, anxiety and coping.     

Accounting for Time Preference in Management Decisions: An Application to Invasive Species

Managers of invasive species seek to prevent and mitigate their impact, which vary in the time horizon over which they are realized. Likewise, stakeholders vary in the time horizons they consider relevant. Agricultural impacts might reasonably be considered over two or three decades, although ecologists typically consider environmental impacts over much longer time frames. Although time preference plays a critical role in decision making, it has largely been ignored in multicriteria analyses. In this study, we examine how time has been treated in previous decision analyses of invasive species management, focusing on the differences between multicriteria and economic cost–benefit analyses. We then outline a method for incorporating time preference information into multicriteria decision analyses to ensure that criteria weights remain a faithful representation of the decision maker's preferences. To illustrate how time preference can be elicited for invasive species problems involving both monetary and nonmonetary consequences, we describe a small empirical study we conducted with a small group of experts and managers. By outlining a way to consider time preference information in multicriteria analyses of invasive species management, we hope to facilitate better decision making that is reflective of the decision maker's true preferences.

A response binding effect in visual short-term memory

The current study aimed to investigate the effect of action on the preservation of stored feature bindings. Prior research suggests that stimuli presented after a memory array can disrupt the feature bindings of memory array items. Here, we conducted three experiments to examine whether response to targets disrupts feature bindings. Two of four letters (A, B, C, D) were presented in a memory array, and were followed by a second array containing a single target letter. After either identifying or localizing the target letter, participants were required to report the identity or location of the memory array items. There was a deficit in memory performance involving spatial repetition when participants were required to localize targets, and involving identity repetition when participants were required to identify targets. We conclude that response codes are fundamentally linked to stimulus representations, and can affect retrieval from visual working memory.

Who is crossing where? Infants' discrimination of figures and grounds in events

To learn relational terms such as verbs and prepositions, children must first dissect and process dynamic event components. This paper investigates the way in which 8- to 14-month-old English-reared infants notice the event components, figure (i.e., the moving entity) and ground (i.e., stationary setting), in both dynamic (Experiment 1) and static representations of events (Experiment 2) for categorical ground distinctions expressed in Japanese, but not in English. We then compare both 14- and 19-month-old English- and Japanese-reared infants’ processing of grounds to understand how language learning interacts with the conceptualization of these constructs (Experiment 3). Results suggest that (1) infants distinguish between figures and grounds in events; (2) they do so differently for static vs. dynamic displays; (3) early in the second year, children from diverse language environments form nonnative – perhaps universal – event categories; and (4) these event categories shift over time as children have more exposure to their native tongue.     

An integrated perspective on the relation between response speed and intelligence

Research in the field of mental chronometry and individual differences has revealed several robust regularities (Jensen, 2006). These include right-skewed response time (RT) distributions, the worst performance rule, correlations with general intelligence (g) that are more pronounced for RT standard deviations (RTSD) than they are for RT means (RTm), an almost perfect linear relation between individual differences in RTSD and RTm, linear Brinley plots, and stronger correlations between g and inspection time (IT) than between g and RTm. Here we show how all these regularities are manifestations of a single underlying relationship, when viewed through the lens of Ratcliff’s diffusion model ( [Ratcliff, 1978] and [Ratcliff et al., 2008] ). The single underlying relationship is between individual differences in general intelligence and individual differences in “drift rate”, which is just the speed of information processing in Ratcliff’s model. We also test and confirm a strong prediction of the diffusion model, namely that the worst performance rule generalizes to phenomena outside of the field of intelligence. Our approach provides an integrative perspective on intelligence findings.
