Executive process training in young and old adults

There is a growing body of research on the modifiability of executive functions in different stages of life. Previous studies demonstrate robust training effects but limited transfer in younger and particularly in older adults. The aim of the present study was to investigate whether a theoretically derived intervention for executive functioning, addressing several basic processes (updating, shifting, and inhibition), can induce transfer effects in early and late adulthood. Fifty-nine healthy adults, 29 young and 30 older adults, were randomly assigned to either training or no-contact control groups. The training groups received 15 sessions of executive process training for about 45 min/session during 5 weeks. A test battery including a criterion task and near, intermediate, and far transfer tasks was administered before and after training. Results showed pronounced age-equivalent gains on the criterion task. Near transfer was seen to non-trained updating and inhibition tasks for the young and older trained participants. However, only the young adults showed intermediate transfer to two complex working memory tasks. No far transfer effects were seen for either age group. These findings provide additional evidence for age-related constraints in the ability to generalize acquired executive skills, and specifically show that training of multiple executive processes is not sufficient to foster transfer beyond the very near in older adults.     

Seeking a Variable Standard of Individual Moral Responsibility in Organizations

Relatively few authors attempt to assess individuals’ moral responsibility for collective action within organizations. I draw on fairly technical recent work by Seamus Miller, Christopher Kutz, and Tracy Isaacs in the field of collective responsibility to see what normative lessons can be prepared for people considering entry into large hierarchical, compartmentalized organizations like businesses or the military. I will defend a view shared by Isaacs that group members’ responsibility for collective action depends on intentions to contribute to particular collective actions, against Miller and Kutz’s more inculpating standards. Miller and Kutz fail to achieve their goal of articulating a variable standard for measuring individual responsibility within organizations, for reasons suggesting we might not be able to do better with their theoretical commitments than a threshold warning for all potential entrants to be wary of the groups they enter. Isaacs sketches an approach that is more successful at creating a variable standard for assessing high echelon actors; I build on and refine her theory to argue that organization members can be held responsible for their unique interpretations of the organization mission and unique contributions to their role duties. High echelon actors may share personal responsibility for their subordinates’ behavior when they have created the conditions for those actions through their unique orders.     

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.
