Simply Satisfied: The Role of Psychological Need Satisfaction in the Life Satisfaction of Voluntary Simplifiers

Low consumption lifestyles have the potential to impact positively on the environment and mental health. Past research indicates that individuals who engage in a low consumption lifestyle known as voluntary simplicity have higher levels of life satisfaction. This investigation aimed to test the role of psychological needs as proposed by Ryan and Deci’s (Am Psychol 55(1):68–78, 2000. doi: 10.1037/0003-066X.55.1.68) self-determination theory, in the relationship between voluntary simplicity and life satisfaction in a sample of 571 adults who may or may not identify as voluntary simplifiers. Self-report data was analysed using structural equation modeling to test a hypothesised path from simplifying behaviours to life satisfaction via gratification of the three proposed psychological needs. Consistent with previous research, simplifying behaviours were associated with increased life satisfaction. The proposed pathway: simplicity—psychological need gratification—life satisfaction was supported in the empirical test of the structural equation model suggesting psychological need satisfaction plays a mediating role in the increased life satisfaction of voluntary simplifiers.     

Hope for the Future and Avoidance of the Present: Associations with Well-being in Older Adults

Positive psychology and third wave cognitive behavioral therapy approaches have seldom been applied to older adults. This study therefore examined whether two concepts drawn from these areas, hope for the future and avoidance in the present, were associated with well-being in a sample of 259 older adults (65–94 years). Hope was measured as a stable trait. Experiential avoidance was measured as avoidance of present internal and external events. Respondents also completed two well-being measures: hedonic (positive and negative affect) and eudeimonic (meaning in life). Path analyses showed that high hope was significantly associated with high positive affect, and high meaning in life; and high experiential avoidance was associated with high negative affect and low meaning in life. This was also true when both (hope and avoidance) were taken into account, along with sociodemographic variables and perceived health. Many of the pathways between hope and well-being, and between experiential avoidance and well-being appear to be bidirectional. However the path from hope to positive affect was stronger than that from positive affect to hope. Further research is needed to clarify each of these points. Both hope for the future and lack of avoidance in the present are important for well-being in older adulthood and interventions targeting these processes may enhance positive aging and contribute to a sense of having a meaningful life.     

Analysis of precursors to multiply controlled problem behavior: A replication

We replicated Fritz, Iwata, Hammond, and Bloom (2013) by evaluating the efficacy of an experimental methodology to identify precursors to aggression displayed by an adolescent with autism spectrum disorder. Using their trial‐based precursor analysis, we identified seven precursors to aggression. Next, we compared the outcomes of separate precursor and aggression functional analyses and showed that both precursors and aggression were multiply controlled by the same variables.     

Evidence and the openness of knowledge

The paper argues that knowledge is not closed under logical inference. The argument proceeds from the openness of evidential support and the dependence of empirical knowledge on evidence, to the conclusion that knowledge is open. Without attempting to provide a full-fledged theory of evidence, we show that on the modest assumption that evidence cannot support both a proposition and its negation, or, alternatively, that information that reduces the probability of a proposition cannot constitute evidence for its truth, the relation of evidential support is not closed under known entailment. Therefore the evidence-for relation is deductively open regardless of whether evidence is probabilistic or not. Given even a weak dependence of empirical knowledge on evidence, we argue that empirical knowledge is also open. On this basis, we also respond to the strongest argument in support of knowledge closure (Hawthorne 2004a). Finally, we present a number of significant benefits of our position, namely, offering a unified explanation for a range of epistemological puzzles.     

Extending SME to Handle Large‐Scale Cognitive Modeling

Analogy and similarity are central phenomena in human cognition, involved in processes ranging from visual perception to conceptual change. To capture this centrality requires that a model of comparison must be able to integrate with other processes and handle the size and complexity of the representations required by the tasks being modeled. This paper describes extensions to Structure‐Mapping Engine (SME) since its inception in 1986 that have increased its scope of operation. We first review the basic SME algorithm, describe psychological evidence for SME as a process model, and summarize its role in simulating similarity‐based retrieval and generalization. Then we describe five techniques now incorporated into the SME that have enabled it to tackle large‐scale modeling tasks: (a) Greedy merging rapidly constructs one or more best interpretations of a match in polynomial time: O(n²log(n)); (b) Incremental operation enables mappings to be extended as new information is retrieved or derived about the base or target, to model situations where information in a task is updated over time; (c) Ubiquitous predicates model the varying degrees to which items may suggest alignment; (d) Structural evaluation of analogical inferences models aspects of plausibility judgments; (e) Match filters enable large‐scale task models to communicate constraints to SME to influence the mapping process. We illustrate via examples from published studies how these enable it to capture a broader range of psychological phenomena than before.     

Changes in positive and negative affect as predictors of change in felt age: Results from the Health and Retirement Study

The present study aimed to examine how changes in positive and negative affect and their interaction predict changes in felt age in a longitudinal design of two waves drawn from the Health and Retirement Study (HRS). Participants (n = 4174) at an average age of 67.97 completed the 2008 and 2012 left behind questionnaire of the HRS. Our results showed that an increase in positive affect and a decrease in negative affect from Wave 1 to Wave 2 predicted an accelerated decrease in felt age. There was an interaction effect showing that for those with an increase in negative affect, a higher change in positive affect predicted reduced odds for accelerated increase in felt age. To conclude, improving favorable change in the combination between positive and negative affect might in turn relate to the individual’s self-perceptions of aging, in the second half of life.     

A randomised wait list-controlled pre–post–follow-up trial of a gratitude diary with a distressed sample

In a randomised wait list-controlled trial with repeated measures pre-, post- and follow-up design, participants (N = 109) with a current self-reported diagnosis of an anxiety disorder and/or depression, took part in an internet-based study. After completing a three-week gratitude diary returning participants had lower scores on measures of depression, anxiety, stress and perceived sleep difficulties and higher scores on a measure of subjective well-being than immediately pre-intervention. At three-week follow-up depression and sleep scores for returning participants were no longer significantly different from pre-intervention, however, improvements for subjective well-being and stress at post-intervention were maintained. At follow-up anxiety scores had not only been maintained but had improved significantly beyond post-intervention results. Intention to treat analyses were conducted and provided support for most completer results. Differences between the two sets of analyses are discussed below. This trial provides support for the use of gratitude diaries as an intervention with distressed populations.
