Love,Power and Consistency: Scotus’ Doctrines of God’s Power,Contingent Creation,Induction and Natural Law

I first examine John Duns Scotus’ view of contingency, pure possibility, and created possibilities, and his version of the celebrated distinction between ordained and absolute power. Scotus’ views on ethical natural law and his account of induction are characterised, and their dependence on the preceding doctrines detailed. I argue that there is an inconsistency in his treatments of the problem of induction and ethical natural law. Both proceed with God’s contingently willed creation of a given order of laws, which can be revoked and replaced with a new order of laws. In the case of ethical natural law God promulgated the Decalogue, for example; in the case of nature, there are physical laws that can be known by induction. Scotus exalts the freedom of God and the mutability of ethical natural law in order to explain exceptions to it disclosed by revelation (for example, the Old Testament command to Abraham to kill Isaac). Yet he treats ethical natural laws as (mostly) not universal and immutable. In contrast, he holds that we can arrive at knowledge of the universal and immutable laws of nature, except for those regularities that result from free will. Finally, I present several ways of characterising this tension between Scotus’ doctrines.     

Synergies between processing and memory in children’s reading span

Previous research has established the relevance of working memory for cognitive development. Yet the factors responsible for shaping performance in the complex span tasks used to assess working memory capacity are not fully understood. We report a study of reading span in 7‐ to 11‐year‐old children that addresses several contemporary theoretical issues. We demonstrate that both the timing and the accuracy of recall are affected by the presence or absence of a semantic connection between the processing requirement and the memoranda. Evidence that there can be synergies between processing and memory argues against the view that complex span simply measures the competition between these activities. We also demonstrate a consistent relationship between the rate of completing processing operations (sentence reading) and recall accuracy. At the same time, the shape and strength of this function varies with the task configuration. Taken together, these results demonstrate the potential for reconstructive influences to shape working memory performance among children.     

The Authority Account of Prudential Options

The Authority Account provides a new explanation why commonsense morality contains prudential options—options that permit agents to perform actions that promote their own wellbeing more than the action they have most reason to do, from the moral point of view. At the core of that explanation are two claims. The first is that moral requirements are traditionally widely taken to have an authoritative status; that is, to be rules that morality (or more specifically some suitable agent or agency, acting on behalf of morality) imposes by right. The second is that in order for moral requirements to have such a status, morality must contain prudential options. If both of these claims are true, then they will create a (rational) pressure to think of morality as containing prudential options. And according to the Authority Account, the fact that commonsense morality contains such options is (at least in significant part) the result of this pressure.     

High Aspirations: Differences in Employee Satisfaction Between University Faculty and Staff

Employee satisfaction surveys were examined for five universities in the US, UK and Canada, selected because they presented results for faculty and other staff separately. Faculty consistently score more negatively on employee satisfaction across a wide range of areas. The most negative responses are for areas such as personal/worklife balance, work demands/workload, university direction, and whether the employee would choose to work at the same institution again/would recommend it for employment. The results are consistent with previous studies which have shown that education level is negatively associated with job satisfaction. The results suggest that university faculty have high aspirations, since in a number of indicators faculty working conditions appear superior to those of staff (tenure; average income; sabbatical leaves; work control; involvement and consultation in university decision-making), although junior faculty prior to tenure may experience more stress than staff. Employers undertaking employee satisfaction surveys need to take into account systematic differences in aspirations among their employees, when interpreting survey results.     

Comparing techniques for estimating automatic retrieval: effects of retention interval

Results from implicit memory (IM) tasks suggest that automatic retrieval remains stable or decreases over time. In contrast, results from the process dissociation approach (PDA) suggest that automatic retrieval may actually increase over time. One explanation for these discrepant results is that performance on IM tasks is contaminated by controlled retrieval strategies, thereby overestimating automatic retrieval, particularly at short retention intervals, when controlled retrieval strategies are high. An alternative explanation is that automatic and controlled retrieval are positively correlated, rather than independent as assumed by the PDA. If so, the PDA would underestimate automatic retrieval, particularly when controlled retrieval strategies are high. Results from a speeded IM task suggest that a standard IM task provided an accurate estimate of automatic retrieval, whereas the PDA underestimated automatic retrieval at a short retention interval. This pattern of underestimation by the PDA supports the conclusion that automatic and controlled retrieval were positively correlated rather than independent.     

Development of and change in cognitive control: A comparison of children, young adults, and older adults

Cognitive control involves adjustments in behavior to conflicting information, develops throughout childhood, and declines in aging. Accordingly, developmental and age-related changes in cognitive control and response-conflict detection were assessed in a response-compatibility task. We recorded performance measures, pre-response time (pre-RT) activity and medial frontal negativity (MFN)—sequentially occurring, putative event-related potential (ERP) indexes, respectively, of cognitive control and response-conflict detection. When response conflict reached the highest levels by requiring incompatible responses on posterror trials, children and older adults showed the greatest performance decrements. ERPs indicated that young adults implemented control (pre-RT) and detected the increased conflict (MFN) only when that conflict was at the highest levels, whereas children and older adults did so at lower levels (e.g., posterror, compatible responses). Consequently, the developmental and age-related performance decrements observed here may be due to the undifferentiated and inefficient manner in which children and older adults recruited the processes associated with both cognitive control and response-conflict detection.     

The self and dreams during a period of transition

The content of dreams and changes to the self were investigated in students moving to University. In study 1, 20 participants completed dream diaries and memory tasks before and after they had left home and moved to university, and generated self images, “I am…” statements (e.g. I am an undergraduate), reflective of their current self. Changes in “I ams” were observed, indicating a newly-formed ‘university’ self. These self, images and related autobiographical knowledge were found to be incorporated into recent dreams but not into dreams from other periods. Study 2 replicated these findings in a different sample (N = 55). We suggest that these data reflect a period of self-consolidation in which new experiences and self images are incorporated into autobiographical memory knowledge structures representing personal goals during sleep.
