Ask and ye shall receive: behavioural specificity in the accuracy of subjective memory complaints

A cross‐sectional sample of adults completed an extensive set of cognitive tasks and a set of questionnaires measuring depressive affect, memory complaint, and other variables. During an interview about their prescribed medications, the participants also reported whether they were having problems remembering to take the medication as prescribed (an everyday prospective memory problem). Their medication adherence at home was then monitored for one month using pill bottles which microelectronic caps. Cognitive tasks correlated with memory complaints, as measured by the Memory Functioning Questionnaire, but not with problems in remembering to take medications. The highest correlations were with a free recall task. Conversely, reported problems with medication adherence during the interview had good predictive validity for subsequent adherence problems, but not for cognitive tasks, including a measure of prospective memory. Depressive affect was related to both the questionnaire and the interview complaints about medication adherence, but a structural equation model showed that the relationships of cognition and medication adherence to the different memory complaints were independent of depressive affect. The results are interpreted in terms of a behavioural specificity hypothesis, which states that adults' self‐reports of memory problems are valid when they focus directly on specific memory‐related behaviours in everyday contexts.

Using intraverbal training to increase symbolic play in children with autism spectrum disorder

We evaluated the effects of an intraverbal training procedure on the acquisition, maintenance, and generalization of object‐substitution symbolic play in three 6‐year‐old Korean boys with autism spectrum disorder. A multiple probe across four behaviors design was used. All children acquired target symbolic play behavior, and novel responses emerged in training and follow‐up conditions. Generalization of object substitutions to untaught objects occurred in all three children. Free play observations indicated that symbolic play emerged in one child, and functional play increased in all three children.     

The Use of Exploratory Factor Analysis and Principal Components Analysis in Communication Research

Exploratory factor analysis is a popular statistical technique used in communication research. Although exploratory factor analysis (EFA) and principal components analysis (PCA) are different techniques, PCA is often employed incorrectly to reveal latent constructs (i.e., factors) of observed variables, which is the purpose of EFA. PCA is more appropriate for reducing measured variables into a smaller set of variables (i.e., components) by keeping as much variance as possible out of the total variance in the measured variables. Furthermore, the popular use of varimax rotation raises some concerns about the relationships among the factors that researchers claim to discover. This paper discusses the distinct purposes of PCA and EFA, using two data sets as examples to highlight the differences in results between these procedures, and also reviews the use of each technique in three major communication journals: Communication Monographs, Human Communication Research, and Communication Research.

Family well-being is valued more than personal well-being: A four-country study

Well-being is recognized as a fundamental human goal and a universal human aspiration. However, some cross-country studies suggest that the desirability of the most often studied concept of well-being—personal life satisfaction—varies across countries, and we know little about the desirability of other types of well-being. Extending this novel area of research, we argue that focusing on the family (as compared to the individual) as the subject of well-being may be another important distinction in how well-being is conceptualized and valued. With data collected in four countries that tend to occupy different positions in rankings of personal life satisfaction (i.e., Canada, Colombia, Japan, and Poland), we document that, irrespective of cultural context, family well-being is valued over personal well-being. These findings suggest that policy makers and scientists may need to pay more attention to family well-being than they currently do.

     

Event-related Desynchronization of Mu Rhythms During Concentric and Eccentric Contractions

The purpose of this study was to compare the electroencephalographic (EEG) patterns and reaction times (RTs) of muscle activation between concentric and eccentric biceps brachii contractions under the RT paradigm and to evaluate how the EEG patterns and RTs changed with practice. Sixteen subjects performed 3 sets of 30 repetitions of submaximal voluntary concentric and eccentric biceps contractions. RT, event-related desynchronization (ERD) patterns of mu rhythm onset, and ERD amplitudes were selectively analyzed. Mental demand decreased as familiarity with the motor action increased due to practice regardless of contraction type. However, the 2 types of muscle contractions still have differences in brain activity regardless of decreased mental demand: eccentric contractions require earlier preparation than concentric contractions.     

Religiosity and Healthy Lifestyle Behaviours in Malaysian Muslims: The Mediating Role of Subjective Well-Being and Self-Regulation

Past research on healthy lifestyle behaviours has been primarily conducted within Western or Judeo–Christian contexts, while non-Western or Muslim contexts remain under-represented. This study examined predictors of healthy lifestyle behaviours (religiosity, goal-setting, impulse control, and subjective well-being) in Malaysian Muslims and explored the mechanisms underlying the relationship between religiosity and healthy lifestyle behaviours. Self-report survey responses from 183 healthy adults (M _age = 28.63 years, 18–50 years) were analysed using regression and multiple mediation analyses. The results indicated that subjective well-being emerged as the strongest predictor, followed by goal-setting. Furthermore, subjective well-being and goal-setting mediated the religiosity–healthy lifestyle behaviour relationship. The findings provide guidance for future health-promoting interventions.
