Some Burning Issues in Research on Health Behavior Change

This response to five excellent commentaries is intended to clarify some issues in research on health behavior change that appear to be ambiguous or controversial, such as the debate about stage models versus continuum models or the search for moderators and mediators. The assumption of stages can be useful, but the quest for truly existing stages is considered fruitless because stage is a scientific construct, not nature. The Health Action Process Approach (HAPA) is designed as an implicit or explicit stage model, based on the distinction between a motivational and a volitional phase. As a template for targeted interventions, it suggests grouping individuals into preintenders, intenders, and actors. Due to indistinct boundaries between stages and to unstable social‐cognitive constructs, the validity of stage assessment becomes the foremost problem. However, if stage‐tailored interventions turn out to be superior to nontailored interventions, then the choice of the corresponding stage model is justified. When analysing the mechanisms of health behavior change or when predicting behaviors, the HAPA is also in line with nonstage (continuum) models. In the latter case, it examines moderators and mediators within a path‐analytic research design. It is suggested that more research be conducted on moderated mediation. Cette réponse aux cinq excellents commentaires tente de clarifier certains des résultats des recherches sur la modification des comportements relatifs à la santé, résultats qui semblent ambigus ou sujets à controverse, ce qui est le cas de la discussion sur les modèles en stades ou en continuum ou encore de la recherche de modérateurs et de médiateurs. L’hypothèse des stades peut se révéler fructueuse, mais il est inutile de considérer que les stades existent réellement puisque le stade, concept scientifique, ne relève pas de la nature. L’Approche des Processus d’Action en faveur de la Santé (HAPA) est par construction un modèle en stades implicites ou explicites basé sur la distinction entre une étape motivationnelle et une étape volitionnelle. Comme cadre pour des interventions ciblées, il propose de regrouper les individus en trois catégories: ceux qui n’ont pas encore l’intention d’agir, ceux qui ont cette intention et enfin ceux qui agissent. En raison des frontières fluctuantes entre les stades et de l’instabilité des concepts socio‐cognitifs, la validité de l’évaluation des stades devient le problème principal. Cependant, si les interventions programmées à partir des stades se révèlent plus efficaces que les autres, le choix de ce modèle est défendable. Quand on analyse les mécanismes des modifications du comportement en faveur de la santé ou quand on prédit ces comportements, l’HAPA accepte aussi le modèle en continuum. En ce cas, elle aborde les modérateurs et les médiateurs avec un plan de recherche en pistes causales. Il faut développer les recherches sur modérateurs et médiateurs.     

The initial capitalization superiority effect in German: evidence for a perceptual frequency variant of the orthographic cue hypothesis of visual word recognition

A perceptual frequency variant of the orthographic cue (OC) hypothesis (Peressotti, Cubelli, & Job, 2003) was tested in two perceptual identification experiments using the variable viewing position technique: German nouns and non-nouns that are most frequently perceived with or without initial letter capitalization, respectively, were tachistoscopically presented in upper-case, lower-case, or with initial capitalization. The results indicated that words were best recognized in the form they are most frequently perceived in, which suggests that during reading acquisition abstract as well as case- and item-specific OCs may be learned and used for recognition.     

Bootstrapping cognition from behavior-a computerized thought experiment

We show that simple perceptual competences can emerge from an internal simulation of action effects and are thus grounded in behavior. A simulated agent learns to distinguish between dead ends and corridors without the necessity to represent these concepts in the sensory domain. Initially, the agent is only endowed with a simple value system and the means to extract low-level features from an image. In the interaction with the environment, it acquires a visuo-tactile forward model that allows the agent to predict how the visual input is changing under its movements, and whether movements will lead to a collision. From short-term predictions based on the forward model, the agent learns an inverse model. The inverse model in turn produces suggestions about which actions should be simulated in long-term predictions, and long-term predictions eventually give rise to the perceptual ability.     

Social-Cognitive Factors in Changing Health-Related Behaviors

Changing health-related behaviors requires two separate processes that involve motivation and volition, respectively. First, an intention to change is developed, in part on the basis of self-beliefs. Second, the change must be planned, initiated, and maintained, and relapses must be managed; self-regulation plays a critical role in these processes. Social-cognition models of health behavior change address these two processes. One such model, the health action process approach, is explicitly based on the assumption that two distinct phases need to be studied longitudinally, one phase that leads to a behavioral intention and another that leads to the actual behavior. Particular social-cognitive variables may play different roles in the two stages; perceived self-efficacy is the only predictor that seems to be equally important in the two phases.     

Beyond sentence boundaries: Grammatical gender information in short-term recall of texts

In the context of text recall it is often stated that surface representations are quickly forgotten. Jarvella (1971) and Sachs (1967) argued that what is retained beyond sentence boundaries is meaning information, whereas lexical and syntactic information is only available for the most recent constituent. We based a text recall experiment on Jarvella’s paradigm, in order to demonstrate that both meaning and grammatical gender information contribute to the recall of short text passages. Although it is known that grammatical gender information is used in anaphor resolution, even if noun and pronoun do not belong to adjacent sentences, there is no direct evidence for a gender contribution to text memory so far. The present experiment demonstrates that grammatical gender information, even when of no semantic importance, is retained beyond sentence boundaries and can contribute to the memory representation of subsequent text.

Assessing the Within‐Trial Treatment Integrity of Discrete‐Trial Teaching Programs Using Sequential Analysis

Discrete‐trial teaching is a strategy frequently used to teach functional skills to individuals with developmental and intellectual disabilities. Research has shown that the within‐trial components of the procedure should be administered with ≥90% treatment integrity to facilitate optimal learning. Usually within‐trial treatment integrity is measured using whole‐session methods such as percentage of trials correctly administered. This study demonstrated one‐step Markov transition matrices as a method of assessing within‐trial treatment integrity. All components of discrete trials were coded and time‐stamped from video recordings of therapist–learner dyads in their typical setting (home or school). Several types of within‐trial treatment integrity errors were identified using the Markov transition matrices, error sequences that could not be identified using a percentage correct analysis. Better identification of errors has the potential both to enhance treatment integrity and to gain efficiency by targeted retraining of therapists. Copyright © 2016 John Wiley & Sons, Ltd.     

One executive function never comes alone: monitoring and its relation to working memory,reasoning, and different executive functions

Monitoring is involved in many daily tasks and is described in several theoretical approaches of executive functioning. This study investigated the relative relationship of cognitive processes that are theoretically relevant to monitoring, such as concept formation, reasoning, working memory, and general cognitive control functions. Data from 699 participants who performed the Balanced Switching Task, aiming at capturing monitoring, were used. Subsamples also performed standard tasks assessing the processes assumed to be related to monitoring. Structural equation modeling revealed that general cognitive control processes are particularly relevant. They mediate the relationship between working memory, reasoning, and monitoring. Updating and maintaining information, as well as concluding from information which strategies can guide behavior toward predefined goals, is required for the ability to exert general cognitive control, which again may be relevant for implementing strategies in a goal-directed way. Together, these processes seem to be necessary to adequately monitor behavior in complex tasks.
