Sexual ethics and communal judgments: on the pluralism of virtues, values, and practices.

Different judgments by Christian communities on issues in sexual ethics involve different weightings of various sources of moral authority, different understandings of the normativity of the natural, and different assessments of the scope of freedom to be exercised in relation to the goods of marriage. These fundamental differences of interpretation can be exemplified by the ongoing Roman Catholic discussion of the legitimacy of voluntary sterilization in certain "hard cases." The contributors to this issue of Christian Bioethics, in their spirited exchange on that issue, exemplify the need for careful attention to the ways that differences of theological emphasis and moral method lead to different judgements in particular cases, both within and between particular Christian communities.     

Does retrieval intentionality really matter? Similarities and differences between involuntary memories and directly and generatively retrieved voluntary memories

Theories of autobiographical memory distinguish between involuntary and voluntary retrieval as a consequence of conscious intention (i.e., wanting to remember). Another distinction can be made between direct and generative retrieval, which reflects the effort involved (i.e., trying to remember). However, it is unclear how intention and effort interacts. For example, involuntary memories and directly retrieved memories have been used interchangeably in the literature to refer to the same phenomenon of effortless, non‐strategic retrieval. More recent theoretical advances suggest that they are separate types of retrieval, one unintentional (involuntary), another intentional and effortless (direct voluntary retrieval), and a third intentional and effortful (generative voluntary retrieval). Whether this also entails differing phenomenological characteristics, such as vividness, rehearsal, or emotional valence, has not been previously investigated. In the current study, participants reported memories in an experimental paradigm designed to elicit voluntary and involuntary memories and rated them on a number of characteristics. If intention affects the retrieval process, then we should expect differences between the characteristics of involuntary and directly retrieved memories. The results imply that retrieval intention seems to differentiate how a memory appears in a person's mind. Furthermore, we argue that these differences in part could result from differences in encoding and consolidation.     

How intention to retrieve a memory and expectation that a memory will come to mind influence the retrieval of autobiographical memories

While involuntary memories are retrieved with no intention and are usually unexpected (when one is not waiting for a memory to arise), voluntary memories are intended and expected (when one is searching and waiting for a memory to arise). The present study aimed to investigate the effects of retrieval intentionality (i.e. wanting to retrieve a memory) and monitoring processes (i.e. waiting for a memory to appear) during autobiographical memory retrieval. In addition, we introduced two novel laboratory conditions that have not been used in previous research on voluntary memories: in the first, participants were asked to report anything they could think of in response to each cue word; in the second, they could skip a word if nothing came to mind. These novel manipulations allowed us to differentiate between voluntary memories retrieved in response to experimenter-generated cues (when participants were forced to provide a memory or a thought for each cue) and self-selected cues (when participants were free to not answer a cue if they found it too difficult). We found that highly accessible memories were mostly experienced when retrieval was involuntary and unexpected, while memories with low accessibility were accessed through intentional retrieval and monitoring processes. Response times for memories recalled in the experimenter-generated cue conditions were longer compared to the self-selected cue conditions. This novel finding shows that experimenter-generated recall favours memories with low accessibility; it further supports the idea that, in a substantial number of trials, voluntary memories are directly rather than effortfully retrieved. The idea that the driving force behind differences between involuntary and voluntary memories is not the intention per se is further discussed.     

Facilitation of return in voluntary orienting to visual attributes1

Abstract: The present study examined the effects of voluntary and automatic orienting after a relatively long interval in an attentional cueing paradigm. Facilitation of return was observed after the voluntary orienting to a designated color (Experiment 1) and motion direction (Experiment 2), whereas inhibition of return was observed after the automatic orienting to an abrupt stimulus onset (Experiment 1). These results suggest that the voluntary orienting to a visual attribute modulates subsequent processes differently from the automatic orienting to an abrupt onset. In the voluntary orienting to visual attributes, it would be advantageous to return attention to the previously attended location, which is a potential source of information.

Remembering successes and failures: rehearsal characteristics influence recollection and distancing

We investigated the relationship between components of rumination, brooding and reflection, and autobiographical remembering by testing whether voluntary and involuntary rehearsal mediated rumination-related variation in the sensory-affective and metacognitive features of memory experience. We focused on achievement and failure memories as both are goal-related events, yet they represent distinct experiences in terms of valence and functionality. For failure memories, brooding was associated with intense recollection and reduced psychological distance. Brooding was related to enhanced distance of achievements, indicating the disruptive effects of brooding on remembering. Although reflection attenuated the recollective experience for both achievement and failure memories, it brought achievement memories to a subjective closer past. Structural equation modelling demonstrated the mediating role of involuntary remembering on the pattern of remembering experience.     

Breaking it or Faking it? Some Critical Thoughts on the Voluntary Suspension of Play and Six Proposed Revisions

The voluntary suspension of play (VSP) is a putative fair play norm that has emerged in the last 20 years in association football, though there is no reason in principle why it is limited to that sport. It occurs in football when an injury appears to have been sustained and another player deliberately puts the ball out of play so that the injury can receive rapid attention. It is widely understood as a positive development within the sport and philosophers have added their support on the basis that VSP is a way of players exercising autonomous moral responsibility. It is represented as a case of athletes putting care for their competitors before care for the contest. In this paper, however, it is argued that moral praise for VSP is misplaced. Attempts to induce a VSP almost always occur when a team is seeking to hold a position within a game. As a delaying tactic, it encourages the faking of injuries, which is all the more reprehensible because it exploits someone else's concern for that apparent injury. Conditions for the possibility of VSP within a sport are analysed as well as conditions for the abuse of VSP. VSP occurs because of a loophole, and ways in which this can be closed are presented. In an appendix, some initial empirical evidence is presented that backs the evaluative claims of the paper.     

The Timing of Conscious Experience: A Critical Review and Reinterpretation of Libet''s Research

An extended examination of Libet's works led to a comprehensive reinterpretation of his results. According to this reinterpretation, the Minimum Train Duration of electrical brain stimulation should be considered as the time needed to create a brain stimulus efficient for producing conscious sensation and not as a basis for inferring the latency for conscious sensation of peripheral origin. Latency for conscious sensation with brain stimulation may occurafterthe Minimum Train Duration. Backward masking with cortical stimuli suggests a 125–300 ms minimum value for the latency for conscious sensation of threshold skin stimuli. Backward enhancement is not suitable for inferring this latency. For determining temporal relations between stimuli that correspond to subjects' reports, theendof cerebral Minimum Train Duration should be used as reference, rather than its onset. Results of coupling peripheral and cortical stimuli are explained by a latency after the cortical Minimum Train Duration, having roughly the same duration as the latency for supraliminal skin stimuli. Results of coupling peripheral stimuli and stimuli to medial lemniscus (LM) are explained by a shorter LM latency and/or a longer peripheral latency. This interpretation suggests a 230 ms minimum value for the latency for conscious sensation of somatosensory near-threshold stimuli. The backward referral hypothesis, as formulated by Libet, should not be retained. Long readiness potentials preceding spontaneous conscious or nonconscious movements suggest that both kinds of movement are nonconsciously initiated. The validity of Libet's measures of W and M moments (Libet et al., 1983a) is questionable due to problems involving latencies, training, and introspective distinction of W and M. Veto of intended actions may be initially nonconscious but dependent on conscious awareness.     

Voluntary parents to multiple children with special needs: A profile

A sample of 18 women and men who accompanied their foster or adopted children with severe developmental disabilities to a medical appointment at Henry Ford's Multidisciplinary Care Clinic during the one-year period and who reported during that appointment that they currently had residing with them at least three foster or adopted children with special needs are described in the context of their parental role vis-a-vis these children. Results of the study are presented through use of a six-part organizational scheme: demographic and social traits of the parents and their focal children (the children being seen at the Clinic that day), the focal children in family context, life satisfactions of the parents, foster or adoption motives (whichever applied), foster or adoption satisfactions, and parental sentiments regarding the children as a group.
