Attachment hierarchies in Bangladeshi women in couple-initiated and arranged marriages

Attachment theory posits that in adulthood, romantic partners typically fill the role of primary attachment figure, yet few studies have examined whether these findings hold in cultures that practice arranged marriage or that emphasise collectivistic values and filial piety. In the current study, we compared attachment hierarchies in 116 Bangladeshi women engaged to be married or in the first 3 years of couple-initiated (also known as love) marriages and arranged marriages. Women in couple-initiated marriages reported greater use of their partners for the attachment functions of safe haven and secure base than women in arranged marriages. However, women in both groups were more likely to identify one of their parents than their partner as their primary attachment figure. Although replication is necessary, these findings suggest that partners may not be universally prioritised above parents in the attachment hierarchy and that attachment theory's assumptions of individuation from parents in adulthood may not apply cross-culturally. Findings are discussed in terms of cultural differences from samples previously represented in attachment research, such as kinship structures, the meaning of marriage and filial piety.     

Problem Solvers Adjust Cognitive Offloading Based on Performance Goals

When incorporating the environment into mental processing (cf., cognitive offloading), one creates novel cognitive strategies that have the potential to improve task performance. Improved performance can, for example, mean faster problem solving, more accurate solutions, or even higher grades at university.¹ Although cognitive offloading has frequently been associated with improved performance, it is yet unclear how flexible problem solvers are at matching their offloading habits with their current performance goals (can people improve goal‐related instead of generic performance, e.g., when being in a hurry and aiming for a “quick and dirty” solution?). Here, we asked participants to solve a cognitive task, provided them with different goals—maximizing speed (SPD) or accuracy (ACC), respectively—and measured how frequently (Experiment 1) and how proficiently (Experiment 2) they made use of a novel external resource to support their cognitive processing. Experiment 1 showed that offloading behavior varied with goals: Participants offloaded less in the SPD than in the ACC condition. Experiment 2 showed that this differential offloading behavior was associated with high goal‐related performance: fast answers in the SPD, accurate answers in the ACC condition. Simultaneously, goal‐unrelated performance was sacrificed: inaccurate answers in the SPD, slow answers in the ACC condition. The findings support the notion of humans as canny offloaders who are able to successfully incorporate their environment in pursuit of their current cognitive goals. Future efforts should be focused on the finding's generalizability, for example, to settings without feedback or with high mental workload.     

Inferences about which of J dependent groups has the largest robust measure of location

Recently, a multiple comparisons procedure was derived with the goal of determining whether it is reasonable to make a decision about which of J independent groups has the largest robust measure of location. This was done by testing hypotheses aimed at comparing the group with the largest estimate to the remaining J − 1 groups. It was demonstrated that for the goal of controlling the familywise error rate, meaning the probability of one or more Type I errors, well-known improvements on the Bonferroni method can perform poorly. A technique for dealing with this issue was suggested and found to perform well in simulations. However, when dealing with dependent groups, the method is unsatisfactory. This note suggests an alternative method that is designed for dependent groups.

Assessment and choice: an operant simulation of foraging in patches

Pigeons were presented with an operant simulation of two prey patches using concurrent random-ratio schedules of reinforcement. An unstable patch offered a higher initial reinforcement probability, which then declined unpredictably to a zero reinforcement probability in each session. A stable patch offered a low but unvarying reinforcement probability. When the reinforcement probability declined to zero in a single step, the birds displayed shorter giving-up times in the unstable patch when the ratio between the initial reinforcement probabilities in the unstable and stable patches was greater and when the combined magnitude of the reinforcement probabilities in the two patches was greater. When the unstable patch declined in two steps, the birds behaved as if their giving-up times were influenced heavily by events encountered during the most recent step of the double-step change. This effect was observed, however, only when the reinforcement probability in that step was .04, not when it was .06. All of these data agree with the predictions of a capture-probability model based on a comparison of the estimated probability of receiving a reinforcer in the current patch with that in alternative patches.     

RALPH WENDELL BURHOE IN HISTORICAL PERSPECTIVE

Abstract. Ralph Burhoe has sought to preserve “traditional religious wisdom,” but he emphasizes science as a new revelation. His relation to philosophical positivism and his insistence on including in a scientific theology only views that reflect the scientific worldview constitute major philosophical and theological problems. This essay considers the influence of several historical precursors—Francis Ellingwood Abbot, George Burman Foster, and Shailer Mathews of the “Chicago School” of theology, Douglas Clyde Macintosh, and, especially, Henry Nelson Wieman—which has contributed to a favorable reception of Burhoe's ideas. Social problems such as the youth revolution of the 1960s and indifference to the lack of intellectual credibility of religious beliefs have, however, hindered reception of his ideas. The conclusion notes some tasks that must yet be accomplished in order to continue Burhoe's work, particularly that of increasing the general level of education in the sciences.     

Application of model-selection criteria to some problems in multivariate analysis

A review of model-selection criteria is presented, with a view toward showing their similarities. It is suggested that some problems treated by sequences of hypothesis tests may be more expeditiously treated by the application of model-selection criteria. Consideration is given to application of model-selection criteria to some problems of multivariate analysis, especially the clustering of variables, factor analysis and, more generally, describing a complex of variables.     

Statistical inference for false positive and false negative error rates in mastery testing

This paper describes an asymptotic inferential procedure for the estimates of the false positive and false negative error rates. Formulas and tables are described for the computations of the standard errors. A simulation study indicates that the asymptotic standard errors may be used even with samples of 25 cases as long as the Kuder-Richardson Formula 21 reliability is reasonably large. Otherwise, a large sample would be required.This work was performed pursuant to Grant No NIE-G-78-0087 with the National Institute of Education, Department of Health, Education and Welfare, Huynh Huynh, Principal Investigator.

Patterns of change in fairness perceptions during the hiring process: A conceptual replication in a controlled context

The present paper tackles a problem in the candidate reactions literature: the replicability of results that emerge when using in vivo and in vitro designs. The current study was designed to provide a conceptual replication of a dynamic model of change in fairness perceptions during the hiring process, using a different research design, different measures, and a different sample than the original paper. A sample of 209 participants in a simulated selection process reported their level of perceived fairness three times: before the testing, after the testing, and after the results were communicated. These results support the results of the original that the construction of fairness perceptions declines in a nonlinear way over time, with high initial levels of fairness perception corresponding to a lower rate of decline, and vice versa. Further analysis revealed no change in the individuals’ conceptualization of perceived fairness nor any shift in the respondents’ use of the measurement scale (i.e., no beta and gamma change were detected).     

Guided search through memory

In “hybrid” search, observers search a visual display for any of several targets held in memory. It is known that the contents of the memory set can guide visual search (e.g., if the memorized targets are all animals, visual attention can be guided away from signs). It is not known if the visual display can guide memory search (e.g., if the memory set is composed of signs and animals, can a visual display of signs restrict memory search to just the signs?). In three hybrid search experiments, participants memorized sets of items that belonged to either one or several categories. Participants were then presented with visual displays containing multiple items, also drawn from one or several categories. Participants were asked to determine if any of the items from their current memory set were present in the visual display. We replicate the finding that visual search can be guided by the contents of memory. We find weaker, novel evidence that memory search can be guided by the contents of the visual display.
