Manipulation of walnuts to facilitate opening by the great spotted woodpecker (Picoides major): is it tool use?

True tool use has been documented in some bird species, but to our knowledge, it has not been shown in woodpeckers. Here, we investigated the ability of Picoides major to open nuts of Juglans mandshurica by consistently inserting walnuts between tree branches in a specific position that facilitated nut opening. As seen in these birds, we showed that woodpeckers removed 96 % of the nuts of J. mandshurica from experimental seed trays and inserted each nut in a precise position that specifically allowed nut cracking. When we inserted nuts in an alternative position, woodpeckers manipulated and repositioned nuts to allow nut opening. In contrast, when we inserted the nuts in positions preferred for nut opening, woodpeckers did not alter their position and instead opened the nuts. We suggest that the origin of this behavior, as in other forms of tool use, likely requires a higher cognitive ability in these birds.     

Prospective memory in children and chimpanzees

Prospective memory (PM) involves remembering to do something at a specific time in the future. Here, we investigate the beginnings of this ability in young children (3-year-olds; Homo sapiens) and chimpanzees (Pan troglodytes) using an analogous task. Subjects were given a choice between two toys (children) or two food items (chimpanzees). The selected item was delivered immediately, whereas the unselected item was hidden in an opaque container. After completing an ongoing quantity discrimination task, subjects could request the hidden item by asking for it (children) or by pointing to the container and identifying the item on a symbol board (chimpanzees). Children and chimpanzees showed evidence of prospective-like memory in this task, as evidenced by successful retrieval of the item at the end of the task, sometimes spontaneously with no prompting from the experimenter. These findings contribute to our understanding of PM from an ontogenetic and comparative perspective.     

Lamentations 5:21 within the Development of Thomas Aquinas' Theology of the Grace of Conversion

As a case study in Thomas Aquinas' use of Scripture, this article examines his appeals to Lamentations 5:21 over the course of his career, highlighting the ways in which it informs the development of his mature theology of the grace of conversion. These considerations show how key Scripture verses not only inspire the material content of Thomas' theology, but also serve as indispensible formal components for its expression.     

Neural correlates of sensory‐enabling presentation: An fMRI study of image zooming and rotation video effects on online apparel shopping

For experience products, such as apparel, sensory‐enabling presentations that provide a sense of tactile experience have been suggested as an effective strategy to reduce perceived risk and increase the likelihood of a pleasurable shopping experience. Using functional Magnetic Resonance Imaging (fMRI), we investigated whether sensory‐enabling presentations, specifically, image zooming and rotation videos, would evoke different cognitive and affective brain functions during product evaluation and purchase decision processes. The results suggested that whereas image zooming may evoke more visual perception in the product evaluation process, the rotation view evokes more mental imagery, pleasure, and reward anticipation during the purchase decision process.

The Relative Importance and Interaction of Contextual and Methodological Predictors of Mean rWG for Work Climate

A variety of collective phenomena are understood to exist to the extent that workers agree on their perceptions of the phenomena, such as perceptions of their organization’s climate or perceptions of their team’s mental model. Researchers conducting group-level studies of such phenomena measure individuals’ perceptions via surveys and then aggregate data to the group level if the mean within-group agreement for a sample of groups is sufficiently high. Despite this widespread practice, we know little about the factors potentially affecting mean within-group agreement. Here, focusing on work climate, we report an investigation of a number of expected contextual (social interaction) and methodological predictors of mean r_WG, a common statistic for judging within-group agreement in applied psychology and management research. We used the novel approach of meta-CART, which allowed us to assess the relative importance and possible interactions of the predictor variables. Notably, mean r_WG values are driven by both contextual (average number of individuals per group and cultural individualism-collectivism) and methodological factors (the number of items in a scale and scale reliability). Our findings are largely consistent with expectations concerning how social interaction affects within-group agreement and psychometric arguments regarding why adding more items to a scale will not necessarily increase the magnitude of an index based on a Spearman-Brown “stepped-up correction.” We discuss the key insights from our results, which are relevant to the study of multilevel phenomena relying on the aggregation of individual-level data and informative for how meta-analytic researchers can simultaneously examine multiple moderator variables.
