Behavioural automaticity moderates and mediates the relationship of trait self-control and physical activity behaviour

Objectives: Trait self-control has been shown to be associated with physical activity behaviour. However, in contrast with the theoretical assumption underlying the strength model of self-control, self-control seems to be more important for automatic compared with controlled behaviours. It is argued that self-control might facilitate the formation of adaptive habits (behavioural automaticity) and therefore enhance health behaviour through an indirect effect. The credibility of this hypothesis was empirically assessed in a proof-of-concept study.

Methods: In a prospective design study with two laboratory sessions, participants (N = 124) completed standardised questionnaires assessing trait self-control and behavioural automaticity as predictors (1st session) and actual physical activity behaviour (after one week) as the dependent variable (2nd session).

Results: The predictive power of self-control was stronger for participants with high behavioural automaticity compared with participants with low behavioural automaticity. Furthermore, automaticity mediated the relationship between self-control and behaviour.

Discussion: Behavioural automaticity appears to be a helpful construct for specifying the relationship between self-control and physical activity. Our results support the approach of effortless self-control and self-control success, an extension of the strength model of self-control which assumes that self-control is helpful in creating effective routines. In future studies, causal relationships should be examined using more robust and rigorous research designs.     

The Lazarus Project and Grace Ministries: The Role of Religious Nonprofits in Addressing Personal and Social Problems

This review essay of Williamson and Hood’s (2016) Psychology and Spiritual Transformation in a Substance Abuse Program: The Lazarus Project examines spiritual transformation in the context of substance abuse and homelessness. The essay first tackles the question of whether change results mostly from individual spiritual transformation experiences or from the social surroundings the converts are part of, based on the author’s research on spiritual transformation and homelessness as well as Williamson and Hood’s work, and then it examines the debate surrounding the application of Foucault’s “technologies of the self” to programs that are similar to the Lazarus Project. The last part of the essay offers a few methodological suggestions for studies of similar projects.

An individual differences perspective on pragmatic abilities in the preschool years

Pragmatic abilities are fundamental to successful language use and learning. Individual differences studies contribute to understanding the psychological processes involved in pragmatic reasoning. Small sample sizes, insufficient measurement tools, and a lack of theoretical precision have hindered progress, however. Three studies addressed these challenges in three- to 5-year-old German-speaking children (N = 228, 121 female). Studies 1 and 2 assessed the psychometric properties of six pragmatics tasks. Study 3 investigated relations among pragmatics tasks and between pragmatics and other cognitive abilities. The tasks were found to measure stable variation between individuals. Via a computational cognitive model, individual differences were traced back to a latent pragmatics construct. This presents the basis for understanding the relations between pragmatics and other cognitive abilities.

Research Highlights

• Individual differences in pragmatic abilities are important to understanding variation in language development.
• Research in this domain lacks a precise theoretical framework and psychometrically high-quality measures.
• We present six tasks capturing a wide range of pragmatic abilities with excellent re-test reliability.
• We use a computational cognitive model to provide a substantive theory of individual differences in pragmatic abilities.

     

Spanish-speaking caregivers’ use of referential labels with toddlers is a better predictor of later vocabulary than their use of referential gestures

Variation in how frequently caregivers engage with their children is associated with variation in children's later language outcomes. One explanation for this link is that caregivers use both verbal behaviors, such as labels, and non-verbal behaviors, such as gestures, to help children establish reference to objects or events in the world. However, few studies have directly explored whether language outcomes are more strongly associated with referential behaviors that are expressed verbally, such as labels, or non-verbally, such as gestures, or whether both are equally predictive. Here, we observed caregivers from 42 Spanish-speaking families in the US engage with their 18-month-old children during 5-min lab-based, play sessions. Children's language processing speed and vocabulary size were assessed when children were 25 months. Bayesian model comparisons assessed the extent to which the frequencies of caregivers’ referential labels, referential gestures, or labels and gestures together, were more strongly associated with children's language outcomes than a model with caregiver total words, or overall talkativeness. The best-fitting models showed that children who heard more referential labels at 18 months were faster in language processing and had larger vocabularies at 25 months. Models including gestures, or labels and gestures together, showed weaker fits to the data. Caregivers’ total words predicted children's language processing speed, but predicted vocabulary size less well. These results suggest that the frequency with which caregivers of 18-month-old children use referential labels, more so than referential gestures, is a critical feature of caregiver verbal engagement that contributes to language processing development and vocabulary growth.

Research Highlights

• We examined the frequency of referential communicative behaviors, via labels and/or gestures, produced by caregivers during a 5-min play interaction with their 18-month-old children.
• We assessed predictive relations between labels, gestures, their combination, as well as total words spoken, and children's processing speed and vocabulary growth at 25 months.
• Bayesian model comparisons showed that caregivers’ referential labels at 18 months best predicted both 25-month vocabulary measures, although total words also predicted later processing speed.
• Frequent use of referential labels by caregivers, more so than referential gestures, is a critical feature of communicative behavior that supports children's later vocabulary learning.
