Diverging Perceptions of Personal Moral Values and the Values of One's Religious Group

A popular notion in many religions is that less pious individuals are also less moral. We sought to test the self-described moral values of religious and nonreligious individuals under the framework of Moral Foundations Theory. In Study 1, we found that atheists differ from Christians in some moral domains. We also found evidence that Christians’ self-ratings are consistently lower than what they perceive to be the moral values of other Christians. This finding contradicts previous findings that suggest that Christians may inflate their positive characteristics relative to their peers in other domains. In Studies 2 and 3, we tested several alternative explanations for this finding. Preliminary evidence suggests that Christians rate their moral values lower in comparison to Christian exemplars such as religious leaders, and not from a sense of humility. In contrast, atheists may not have exemplars for such a comparison.     

Examination of a Regressive Prompt-Delay Procedure for Improving Sight-Word Reading

The current two-experiment study examined the effects of a regressive prompt-delay procedure on sight-word reading of four elementary school students. In contrast to traditional progressive prompt-delay procedures in which the latency of prompts is increased, the regressive prompt-delay latency is decreased over time. Data indicate that participants learned sight words quickly and maintained responding at high levels when instruction was withdrawn across both regressive and progressive prompt-delay conditions. Results are discussed in context of empirically supported prompting strategies and possible motivating operations that might be introduced when the learner is instructed to respond more quickly than the experimenter in regressive prompt delay (e.g., a game-like activity that potentially makes the activity educational, engaging, and enjoyable for students).     

High Hopes? Educational,Socioeconomic, and Ethnic Differences in Parents’ Aspirations for their Unborn Children

Parents’ aspirations shape children’s development. In this study, over 6700 pregnant women and over 4300 of their partners from the Growing Up in New Zealand cohort responded to a question about their hopes, dreams, and expectations for their unborn children. Responses were coded according to a Maslowian hierarchy of needs. Mothers and their partners predominantly mentioned self-actualization and physiological aspirations for their unborn children, but their responses varied as a function of parental ethnicity and level of educational achievement and less so as a function of socioeconomic status. Mothers of European ethnicity, and parents with higher levels of educational achievement, mentioned more aspirations for their children—especially for self-actualization and belonging—than mothers of non-European ethnicity and parents with lower levels of educational achievement. These findings are discussed with respect to Maslowian theory and cultural developmental theories, and in terms of understanding the aspirations of parents from diverse backgrounds.     

Scaling reward value with demand curves versus preference tests

In Experiment 1, six capuchins lifted a weight during a 10-min session to receive a food piece. Across conditions, the weight was increased across six different amounts for three different food types. The number of food pieces obtained as a function of the weight lifted was fitted by a demand equation that is hypothesized to quantify food value. For most subjects, this analysis showed that the three food types differed little in value. In Experiment 2, these monkeys were given pairwise choices among these food types. In 13 of 18 comparisons, preferences at least equaled a 3-to-1 ratio; in seven comparisons, preference was absolute. There was no relation between values based on degree of preference versus values based on the demand equation. When choices in the present report were compared to similar data with these subjects from another study, between-study lability in preference emerged. This outcome contrasts with the finding in demand analysis that test–retest reliability is high. We attribute the unreliability and extreme assignment of value based on preference tests to high substitutability between foods. We suggest use of demand analysis instead of preference tests for studies that compare the values of different foods. A better strategy might be to avoid manipulating value by using different foods. Where possible, value should be manipulated by varying amounts of a single food type because, over an appropriate range, more food is consistently more valuable than less. Such an approach would be immune to problems in between-food substitutability.     

The moment‐to‐moment pitch dynamics of child‐directed speech shape toddlers’ attention and learning

Young children have an overall preference for child‐directed speech (CDS) over adult‐directed speech (ADS), and its structural features are thought to facilitate language learning. Many studies have supported these findings, but less is known about processing of CDS at short, sub‐second timescales. How do the moment‐to‐moment dynamics of CDS influence young children's attention and learning? In Study 1, we used hierarchical clustering to characterize patterns of pitch variability in a natural CDS corpus, which uncovered four main word‐level contour shapes: ‘fall’, ‘rise’, ‘hill’, and ‘valley’. In Study 2, we adapted a measure from adult attention research—pupil size synchrony—to quantify real‐time attention to speech across participants, and found that toddlers showed higher synchrony to the dynamics of CDS than to ADS. Importantly, there were consistent differences in toddlers’ attention when listening to the four word‐level contour types. In Study 3, we found that pupil size synchrony during exposure to novel words predicted toddlers’ learning at test. This suggests that the dynamics of pitch in CDS not only shape toddlers’ attention but guide their learning of new words. By revealing a physiological response to the real‐time dynamics of CDS, this investigation yields a new sub‐second framework for understanding young children's engagement with one of the most important signals in their environment.     

Understanding culture across species

Recent claims of culture in great apes have provoked fervent argument about the 'true' definition of culture, most of which has been unhelpful. Instead, a range of definitions should be used to explore different aspects of the cognitive processes that together result in human culture, many of which can be productively studied in non-humans. A richer cognitive account of the contents of culture needs to be developed and used to compare animal and human cultures, instead of sterile searching for a cognitive Rubicon between them. Exploring six views of culture, this article highlights the fundamental contrast of whether culture evolves as a by-product of cumulative change in cognitive mechanisms, or whether it is actively selected for its advantages.
