Explorations of familiarity produced by words with specific combinations of letters

We explore familiarity-based recognition using a paradigm devised by Parkin et al. (2001). The task consists of the creation of two lists of words written with one of two different subsets of letters of the alphabet. We manipulated study time (50, 100, 200, 500 ms per word) of words with different letter probabilistic structure to those originally used by Parkin et al. Letter-based familiarity responding was robust and present even at rates producing otherwise chance performance. A second experiment and structural equation modelling led us to interpret the results from the point of view of a theory that takes into account the processing of similarities and differences (Hunt & MacDaniel, 1993). Finally, our data indicate that the experimental procedure devised by Parkin et al. is an excellent tool with which to study familiarity, once the structure of probabilities of individual letters is considered as the key factor in inducing the effect.

Dispositional hope and life satisfaction among older adults attending lifelong learning programs

BACKGROUND The aim of this study is to explore the indirect effects of dispositional hope in the life satisfaction of older adults attending a lifelong learning program at the University of Valencia, Spain. We examine the mediating impact of dispositional hope regarding its ability to impact life satisfaction while considering affective and confidant social support, perceived health and leisure activities, consciousness and spirituality as predictors. METHODS Analysis were based on survey data (response rate 77.4%) provided by 737 adults 55 years old or more (Mean age=65.41, SD=6.60; 69% woman). A structural model with latent variables was specified and estimated in Mplus. RESULTS The results show the ability of just a few variables to sum up a reasonable model to apply to successful aging population. All these variables are correlated and significantly predict hope with the exception of health. The model additionally includes significant positive indirect effects from spirituality, affective support and consciousness on satisfaction. The model has a good fit in terms of both the measurement and structural model. Regarding predictive power, these comprehensive four main areas of successful aging account for 42% of hope and finally for one third of the life satisfaction variance. CONCLUSIONS Results support the mediating role of dispositional hope on the life satisfaction among older adults attending lifelong learning programs. These findings also support the MacArthur model of successful aging adapted to older adults with high levels of functional, social and cognitive ability. Dispositional hope, perceived health, and social support were the strongest predictors of satisfaction with life.

Method Effects and Gender Invariance of the Rosenberg Self-esteem Scale: A Study on Adolescents

Abstract Rosenbergs self-esteem scale has been extensively used in all areas of psychology to assess global self-esteem (Rosenberg, 1965, 1979). Its construct validity, and specifically its factor structure, has almost from the beginning been under debate. More than four decades after its creation the cumulated evidence points that the scale measures a single trait (self-esteem) but confounded by a method factor associated to negatively worded items. The aim of the study is to examine the measurement invariance of the RSES by gender and test potential gender differences at the latent (trait and method) variable level, while controlling for method effects, in a sample of Spanish students. A series of completely a priori structural models were specified, with a standard invariance routine implemented for male and female samples. The results lead to several conclusions. Conclusions: a) the scale seem gender invariant for both trait and method factors; b) there were small but significant differences between males and females in self-esteem, differences that favored male respondents; and c) there were statistically non-significant differences between men and women in the method factors latent means.

Apoyo docente, compromiso académico y satisfacción del alumnado universitario

The aim of this paper is to analyze the infl uence of academic engagement on university students’ satisfaction with their faculty from teachers’ autonomy support. Scales of Autonomy Support, Academic Engagement and Satisfaction with the Faculty are administered to 870 Dominican university students (50.6% male and 49.4% female). Confi rmatory Factor Analysis and Structural Equation Modelling are carried out. The results refl ect the infl uence of teachers’ autonomy support on the satisfaction with the faculty mediated by academic engagement, as well as the direct effect of perception of teachers’ autonomy support on university students’ satisfaction with their educational center.

Motives to practice exercise in old age and successful aging: A latent class analysis

PURPOSE The aim was to classify motives for exercising trying to find sets of related cases that share common motivations, and to relate these latent classes to markers of successful aging. METHODS 725 old adult aged 55 to 97 years were sampled in several Spanish towns. INSTRUMENTS Successful Aging Inventory (SAI), International Physical Activity Questionnaire (IPAQ), Health Survey SF-8, Satisfaction with Life Scale (SWLS), and motives to practice exercise, were used. Latent Class Analyses (LCAs) were estimated. The classes obtained were compared on markers of successful aging. RESULTS Three latent classes were deemed optimal. Significant differences for several markers of successful aging were found. CONCLUSION A main conclusion derived from the results is that not all old people do exercise for the same motives, and the class of motives you are in had an impact/relation on markers of successful aging. Motives related to internal rather than external pressures should be promoted in the old age.
