A computer-automated laboratory for studying complex perception-action skills

In this paper, we describe a computer-based laboratory for collecting and analyzing real-time performance and eye-movement data by using video game-like tasks. These tasks assess skills that require the integration of varying numbers of perception and action components. Customized hardware and software are described for configuring tasks, collecting data, reconstructing performance, and organizing, editing, and reducing data. General design considerations are emphasized for solving several of the problems encountered in constructing a real-time data collection system. The paper concludes with examples of data that illustrate the system’s usefulness for studying complex perception-action skills.     

Intense classification training to increase the detection of drowning swimmers

Lifeguards engage in a continuous process of deciding whether swimmers are in danger or not. The variety of behaviours that distressed swimmers show makes it difficult to impart declarative knowledge to this effect during lifeguard training. As an alternative, we propose a novel training tool that requires novice participants to rapidly categorise 3-s video clips of real-life swimmers as either ‘safe’ or ‘drowning’. A control group also completed a sham intervention, with surfers that may ‘fall’. Due to the complex nature of swimming pools, a scaffolded training approach was employed, which gradually increased the amount of background information over subsequent training rounds. Results demonstrated that the drowning classification training improved responses in a subsequent drowning detection test, compared with the active control-group. The scaffolded approach appeared to prepare participants for processing swimmers in the drowning-detection test. The results provide a foundation for a novel training protocol to improve lifeguard skills.     

A Latent Growth Curve Modeling Approach to Pooled Interrupted Time Series Analyses

This paper presents a latent variable approach for the estimation of treatment effects within a pooled interrupted time series (ITS) design. Although considered quasi-experimental, the ITS design has been noted as representing one of the strongest alternatives to the randomized experiment, making it highly appropriate for use in documenting the presence of effects that might warrant further evaluation in a large-scale randomized study. Results suggest that the latent variable growth modeling (LGM) is capable of detecting simultaneous differences in both level and slope, and provides tests of significance for these two necessary indicators of an ITS intervention effect. As shown in the analyses, the LGM framework provides a comprehensive and flexible approach to research design and data analysis, making available to a wide audience of researchers an analytical framework for a variety of analyses of growth and developmental processes.     

Positive Emotional Experiences in Scottish and Italian Young Adults: a Diary Study

This research focused on the nature and frequency of positive emotion in a sample of Scottish and Italian young adults and is part of larger scale on-going cross-cultural studies on positive emotion, well-being and happiness. A total of 1043 positive incidents were collected from 157 students who completed diaries in the two countries. Positive incidents were frequent in the course of daily life and were triggered by a wide variety of personal, social and environmental antecedents. Although each culture had a very similar life-satisfaction rating some cultural differences in the phenomenology of positive incidents and their emotions still emerged. As hypothesised Italian and Scottish cultures differed in the domain of independence and interdependence. Italians reported more social interactions involving talking with another and intimacy with a significant other. The Scots, in contrast, reported positive feelings associated with relaxation and being alone as frequently as other social categories, thus exemplifying independence. Recording positive incidents, as they occur moment to moment deconstructs the global and retrospective study of subjective well-being and happiness and fulfills the necessity for ecologically valid research.     

Evaluating a model of global psychophysical judgments—II: Behavioral properties linking summations and productions

Steingrimsson and Luce [Journal of Mathematical Psychology, in press] outlined the second author's proposed psychophysical theory [Luce (2002), Psychological Review, 109, 520-532; Luce (2004a) Psychological Review, 111, 446-454] and tested behavioral attributes that, separately, gave rise to two psychophysical functions, Ψ_⊕ and Ψ_°p. The function Ψ_⊕ maps pairs of physical intensities onto the positive real numbers and represents subjective summation, and the function Ψ_°p represents a form of ratio production. This article evaluates properties linking summation and production in such a way as to force Ψ_°p=Ψ_⊕=Ψ. These properties, which are a form of distributivity, are subjected to an empirical evaluation in three experiments. The testing strategy is carried out in the auditory domain and concerns the subjective perception of loudness. Considerable support is provided for the existence of a single function Ψ for both summation and ratio production.     

Hegel on Private Property: A Contextual Reading

Hegel is often read as defending private property and property rights on the basis of the so‐called “developmental thesis,” which holds that the institution of private property is a necessary condition for individuals to develop the basic capabilities required for free choice. In this paper, I challenge the developmental thesis, and present my own interpretation of Hegel's justification of private property and theory of property rights. Reconstructing Hegel's theory requires that we read the Philosophy of Right as a whole and consider the role of property within the context of the political system that Hegel sketches there, rather than merely looking at the Property subsection of the work in isolation, as works that argue for the developmental thesis tend to do.     

Emotion Regulation of Preschool Children in Foster Care: The Influence of Maternal Depression and Parenting

Emotion regulation is a core developmental process that is related to children’s academic success and mental health. A small body of research has documented that maltreated children show deficits in this developmental arena. The current study was designed to add to the limited literature on emotion regulation in maltreated children in foster care. Emotion regulation tasks were administered to preschool foster children, videotaped, and later coded. Parenting was assessed via coded observations of mother-child interactions. Mothers reported on their experience of depressive symptomatology. We examined the relation of foster parenting and foster mother depression, as well as child characteristics and child welfare experiences, to emotion regulation, specifically in the joy and anger domains. Findings revealed that maternal depression and parental structuring significantly contributed to children’s anger regulation, but not to their regulation of joy. These findings are considered in the context of future research with respect to young maltreated children in foster care.     

Revised Provisional Diagnostic Profile: 2016

ABSTRACT

In Anna Freud’s and other previous versions of the diagnostic profile, drive theory and the structural model were the central organizing concepts. Though these are retained in the current version, greater emphasis has been made of other conceptual perspectives. In particular, the importance of understanding the impact of the child’s external world and the child’s attachment security; also the central importance of affects, both their recognition and management. These changes are seen in such sections as those on the ego which has been expanded to include a section on play and affects. The developmental line of anxiety and the concept of theory of mind have also been added.     

Thieves of thankfulness: Traits that inhibit gratitude

If gratitude is important to well-being, it is important to understand the factors that might inhibit gratitude. The purpose of this study was to investigate four putative inhibitors of gratitude: narcissism, cynicism, materialism/envy, and indebtedness. We used a prospective design where participants were administered measures related to the putative inhibitors along with trait and state gratitude, 2 months apart. After controlling for initial levels of gratitude, Time 1 narcissism, cynicism, and materialism/envy were negatively associated with Time 2 state gratitude. Evidence also supported the theory that narcissism and cynicism may interact in a vicious cycle over time. We conclude that narcissism, cynicism, and materialism inhibit state gratitude, and narcissism and cynicism may be the foundational ‘thieves of thankfulness.’
