Understanding the relationships between age,gender, and life satisfaction: the mediating role of stress and religiosity

Although hundreds of investigations have examined the relationship between age and life satisfaction, a recent review of these studies reveals that relatively little is known about the nature of this relationship, especially between genders and across cultures, and the mechanisms that link age to life satisfaction. Using a large-scale study in Malaysia, the present research explores the mediating effects of stress and religiosity that might be responsible for the empirical findings reported in previous studies. Contrary to previous findings based on US studies, this study finds that women are more satisfied with their lives than men in the early and later stages of life. Chronic stress and religiosity were found to partially mediate the relationship between age and life satisfaction, suggesting that these may be mechanisms that explain the findings of previous studies.     

Categorical Abstract Algebraic Logic: Behavioral π-Institutions

Recently, Caleiro, Gon¸calves and Martins introduced the notion of behaviorally algebraizable logic. The main idea behind their work is to replace, in the traditional theory of algebraizability of Blok and Pigozzi, unsorted equational logic with multi-sorted behavioral logic. The new notion accommodates logics over many-sorted languages and with non-truth-functional connectives. Moreover, it treats logics that are not algebraizable in the traditional sense while, at the same time, shedding new light to the equivalent algebraic semantics of logics that are algebraizable according to the original theory. In this paper, the notion of an abstract multi-sorted π-institution is introduced so as to transfer elements of the theory of behavioral algebraizability to the categorical setting. Institutions formalize a wider variety of logics than deductive systems, including logics involving multiple signatures and quantifiers. The framework developed has the same relation to behavioral algebraizability as the classical categorical abstract algebraic logic framework has to the original theory of algebraizability of Blok and Pigozzi.     

What to do with a forecast?

In the literature one finds two non-equivalent responses to forecasts; deference and updating. Herein it is demonstrated that, under certain conditions, both responses are entirely determined by one’s beliefs as regards the calibration of the forecaster. Further it is argued that the choice as to whether to defer to, or update on, a forecast is determined by the aim of the recipient of that forecast. If the aim of the recipient is to match their credence with the prevailing objective chances, they should defer to the forecast; if it is to maximize the veritistic value of their beliefs, they should update on the forecast.     

Exploring Differential Subgroup Functioning on SAT Writing Items: What Happens When English Is Not a Test Taker's Best Language?

The purpose of this study is to explore patterns in model-data fit related to subgroups of test takers from a large-scale writing assessment. Using data from the SAT, a calibration group was randomly selected to represent test takers who reported that English was their best language from the total population of test takers (N = 322,011). A reference scale for the items was constructed based on EBL responses. Response behaviors of test takers who reported that English was not their best language (ENBL) were examined in relationship to this reference scale. This study illustrates the use of differential subgroup analyses to identify patterns related to person misfit within subgroups, as well as subsets of items, that may affect the validity of writing scores for ENBL test takers. The methodology described here offers an approach that can be used to explore, understand, and improve the validity of scores obtained from ENBL test takers in large-scale writing assessments.     

Terms of the debate on the format and structure of visual memory

Our ability to actively maintain information in visual memory is strikingly limited. There is considerable debate about why this is so. As with many questions in psychology, the debate is framed dichotomously: Is visual working memory limited because it is supported by only a small handful of discrete “slots” into which visual representations are placed, or is it because there is an insufficient supply of a “resource” that is flexibly shared among visual representations? Here, we argue that this dichotomous framing obscures a set of at least eight underlying questions. Separately considering each question reveals a rich hypothesis space that will be useful for building a comprehensive model of visual working memory. The questions regard (1) an upper limit on the number of represented items, (2) the quantization of the memory commodity, (3) the relationship between how many items are stored and how well they are stored, (4) whether the number of stored items completely determines the fidelity of a representation (vs. fidelity being stochastic or variable), (5) the flexibility with which the memory commodity can be assigned or reassigned to items, (6) the format of the memory representation, (7) how working memories are formed, and (8) how memory representations are used to make responses in behavioral tasks. We reframe the debate in terms of these eight underlying questions, placing slot and resource models as poles in a more expansive theoretical space.     

Mentor status,occupational context,and protégé career outcomes: Differential returns for males and females

We report two studies examining the moderating effects of mentor status and protégé gender, along with the moderating role of occupational context, in the relationship of mentoring with protégé career outcomes. Our research replicates and extends previous findings, especially those by Ramaswami et al. (2010b). Results from Study 1 indicated that business school alumni with senior-male mentors earned more compensation than those with no mentors. Additionally, a 3-way interaction (protégé gender × senior-male mentor × occupation type) indicated that the senior-male mentor effect for compensation was especially prominent for females in male-gendered occupation types. Study 2, conducted in an aerospace manufacturing firm comprising both a male-gendered occupation and industry context, confirmed mentor-status by protégé gender interaction for compensation. Female protégés with senior mentors received more compensation than females with no mentors, and also more compensation than males with senior mentors. In contrast, protégés with “other” (not senior) mentors received less compensation than those with no mentors, with this negative effect being especially strong for females. Taken as a whole, these results confirm the importance of mentor status for protégé career success. The results also underscore the importance of considering both mentor attributes and work context in understanding male and female protégés' career returns from mentoring.     

Complexity of interruptions: Evidence supporting a non-interruption-based theory

Interruptions are known to be pervasive and harmful for concentration. It is also known that many factors can influence their effect, such as the complexity of the interrupting task. Less, however, is known about the processes underlying the resumption of the primary task, especially if the interrupting task is complex. Many hypotheses have been proposed but, as yet, it has not been possible to distinguish between their various qualities. In the current study, we carried out two experiments in which we manipulated the complexity of the interrupting task (either simple or complex) and the time between the end of the interrupting task and the resumption of the primary task (i.e., a break). Results showed that complex interrupting tasks led to longer resumption lags (RL) when there was no break, as has already been shown many times. However, while RL after simple interrupting tasks did not change as the break before resumption lengthened up to 1,500 ms, those after complex interrupting tasks decreased. Moreover, after a break of 3,000 ms, RL were longer overall. These results can only support the hypothesis based on task-switching theories, but not hypotheses derived from interruption-based models. Our findings therefore provide empirical evidence in support of explanations of complexity effects and the implications for research and application are discussed.
