From intentions via planning and behavior to physical exercise habits

ObjectivesIndividuals who enact a health behavior effortlessly with minimal conscious deliberation can be assumed to have formed a healthy habit. This can be reflected by increases in self-reported habit strength of a behavior. We examined whether physical exercise intentions facilitate changes in exercise habit strength by increasing the use of action planning and exercise.DesignTwo field studies investigated the effect of behavioral intentions on changes in habit strength through a sequential path from action planning to exercise.MethodExercise intentions, action planning, habit strength, and exercise were assessed at two measurement points in time in 231 university students (Study 1), and at four points in time in 134 rehabilitation patients (Study 2).ResultsIn multiple-step mediation models in both samples, there were indirect effects of intentions on habit strength through action planning and behavior.ConclusionAction planning and behavior operated as sequential mediators to bridge the gap between intentions and habit strength. Exercise habit strength may increase as a result of conscious action planning and frequent behavior enactment. Including these constructs jointly into behavior change models may improve the understanding of the mechanisms involved in behavior maintenance.     

Making Reading More Difficult: A Degraded Text Microworld for Teaching Reading Comprehension Strategies

We present an empirical study that investigated seventh-, ninth-, and eleventh-grade students’ understanding of the infinity of numbers in an interval. The participants (n = 549) were asked how many (i.e., a finite or infinite number of numbers) and what type of numbers (i.e., decimals, fractions, or any type) lie between two rational numbers. The results showed that the idea of discreteness (i.e., that fractions and decimals had “successors” like natural numbers) was robust in all age groups; that students tended to believe that the intermediate numbers must be of the same type as the interval endpoints (i.e., only decimals between decimals and fractions between fractions); and that the type of interval endpoints (natural numbers, decimals, or fractions) influenced students’ judgments of the number of intermediate numbers in those intervals. We interpret these findings within the framework theory approach to conceptual change.     

The Neuroimaging of Long-term Memory Encoding Processes

There needs to be more crosstalk between the lesion and functional neuroimaging memory literatures. This is illustrated by a discussion of episode and fact encoding. The lesion literature suggests several hypotheses about which brain regions underlie the storage of episode and fact information, which can be explored by functional neuroimaging. These hypotheses have been underexplored because neuroimaging studies of encoding have been insufficiently hypothesis-driven and have not controlled encoding-related processes sufficiently well to allow clear interpretations of results to be made. Nevertheless, there is good evidence that certain kinds of associative encoding and/or consolidation are sufficient to activate the medial temporal lobes, and preliminary evidence that some kinds of associative priming may reduce activation of this region. It remains to be proved that attentional orienting to certain kinds of novel information activates the medial temporal lobes. Evidence is growing that the HERA model, developed from neuroimaging rather than lesion data, requires modification and that frontal cortex encoding activations are probably caused by executive processes that are important in effortful memory processing. Neuroimaging studies allow the detection of encoding-related activations in previously unexpected brain regions (e.g. parietal lobes) and, in turn, these findings can be explored with lesion studies.     

Perceptions of coparenting in foster care

Although literature supports the association between harmonious coparenting practices and lowered child problems, little is known about coparenting influences among family constellations in the foster care system. Via a compilation of a new coparenting practices measure, we examined similarities and differences on foster parent-derived perceptions of support/flexibility, shared communication, conflict/triangulation, and total coparenting between foster and biological parents and their independent contribution to child internalizing and externalizing problems. Self-reports were gathered from foster parents (N=80) in 2 groups: kin and nonkin. As compared with nonkin, kin foster parents reported higher perceived support/flexibility, shared communication, and total coparenting. A tendency for higher conflict/triangulation among kin foster parents was also found. After considering foster parent group, psychological distress, and harsh discipline, hierarchical regression analyses revealed that perceived total coparenting and conflict/triangulation contributed to child internalizing and externalizing problems. Results support the linkage between perceptions of coparenting and child problems among caregivers (foster and biological alike) in kin and nonkin arrangements and highlight training in coparenting in general, and conflict management in particular, as an important intervention focus to reduce the high level of child problems in this vulnerable population.     

Psychometric properties of the Coping Response Inventory with Brazilian adolescents

To analyze the psychometric properties of the Coping Response Inventory-Youth Form (CRI-Y) and its applicability, 426 Brazilian adolescents (43.3% boys, 56.7% girls), ages 12 to 18 years (M = 16.5, SD = 1.6), completed the authorized Brazilian/Portuguese version of the 1993 original. Analysis showed higher use of Approach coping and Emotional Discharge by the girls. The inventory showed internal consistency reliability was similar to that of the original scale. A two-factor structure reflecting Approach and Avoidance coping was found; however, the distribution of loadings of specific coping scales on this two-factor structure did not fit the original Moos model. The criterion validity analyzed by the use of the Youth Self-Report showed significant positive relation between the Avoidance dimension and Psychopathological symptoms for boys and girls. Data were discussed with respect to coping theory, assessment, and cultural influences.     

Adaptation of a behavioral parent‐training curriculum for Hispanic caregivers: HOT DOCS Español

This article presents the process utilized to adapt a behavioral parent‐training curriculum for Hispanic caregivers from a program currently available in English. Throughout this process, a number of cultural and language elements were identified as needing to be modified to meet the needs of the Hispanic population served. Fidelity and fit were balanced to develop a curriculum acceptable to diverse Hispanic caregivers while also incorporating all the essential elements of a theory‐based approach to training caregivers. The lessons learned from this adaptation may assist others in their attempts to meet the needs of Hispanic families.     

Gutachtenleitfaden

The article presents an operationalized and manualized approach for the assessment of the capability of performance. This manual has been conceptualized and tested empirically by a multicentric and interdisciplinary workgroup. It is basically oriented to the “International Classification of Functioning” (ICF; WHO), which is well accepted for assessing the course of chronic diseases and the consequences for the individual. It is especially widely applied in the context of rehabilitation. The different diagnostic levels of the manual and their operationalization are outlined. Furthermore, the first results concerning reliability, content validity, applicability and practicability are described and questions on the areas of application of the instrument are discussed.     

Cognitive aspects of congenital learned helplessness and its reversal by the monoamine oxidase (MAO)-B inhibitor deprenyl

Cognitive processes are assumed to change with learned helplessness, an animal model of depression, but little is known about such deficits. Here we investigated the role of cognitive and related functions in selectively bred helpless (cLH, n = 10), non-helpless (cNLH, n = 12) and wild type (WT, n = 8) Sprague Dawley rats. The animals were exposed to an open field for 10 min on each of two test days. On the third day, an object exploration paradigm was carried out. The animals were later tested for helplessness. Both cLH and cNLH rats were more active than WTs on the first day in the open field. Over trials, cNLH and WT rats lowered their activity less than cLH rats. This resistance-to-habituation co-varied with a resistance to develop helplessness. In cLH rats, higher ‘anxiety’ or less time spent in the center of the open field co-varied with severe helplessness. In WTs, a greater reactivity to novel objects and to a spatially relocated object predicted lower levels of helplessness. In cLH rats (n = 4–5 per group), chronic treatment with a high dose of the monoamine oxidase (MAO)-B inhibitor deprenyl (10 mg/kg; i.p.), an anti-Parkinson, nootropic and antidepressant drug, attenuated helplessness. Remarkably, helplessness reversal required the experience of repeated test trials, reminiscent of a learning process. Chronic deprenyl (10 mg/kg; i.p.) did not alter locomotion/exploration or ‘anxiety’ in the open field. In conclusion, helplessness may be related to altered mechanisms of reinforcement learning and working memory, and to abnormalities in MAO-A and/or MAO-B functioning.
