Multiple aspects in the sense of agency

Recent significant research in a number of disciplines centers on the concept of the sense of agency. Because many of these studies cut across disciplinary lines there is good reason to seek a clear consensus on what ‘sense of agency’ means. In this paper I indicate some complexities that this consensus might have to deal with. I also highlight an important phenomenological distinction that needs to be considered in any discussion of the sense of agency, regardless of how it gets defined. Finally, I suggest that the sense of agency has an ambiguous phenomenology and I offer some critical comments on current models that fail to notice this ambiguity.     

Investigating the dose-response relationship between motor imagery and motor recovery of upper-limb impairment and function in chronic stroke: A scoping review

The recovery of upper-limb impairment and dysfunction post-stroke is often incomplete owing to the limited time in therapy focused on upper-limb recovery and the severity of the impairment. In these cases, motor imagery (MI) may be used as a precursor to physical therapies to initiate rehabilitation early on when it would be otherwise impossible to engage in therapy, as well as to increase the dose of therapy when MI is used in adjunct to physical therapy. While previous reviews have shown MI to be effective as a therapeutic option, disparity in findings exists, with some studies suggesting MI is not an effective treatment for post-stroke impairment and dysfunction. One factor contributing to these findings is inconsistency in the dose of MI applied. To explore the relationship between MI dose and recovery, a scoping review of MI literature as a treatment for adult survivors of stroke with chronic upper-limb motor deficit was performed. Embase, Medline and CINHAL databases were searched for articles related to MI and stroke. Following a two-phase review process, 21 papers were included, and data related to treatment dose and measures of impairment and function were extracted. Effect sizes were calculated to investigate the effect of dosage on motor recovery. Findings showed a high degree of variability in dosage regimens across studies, with no clear pattern for the effect of dose on outcome. The present review highlights the gaps in MI literature, including variables that contribute to the dose-response relationship, that future studies should consider when implementing MI.     

Experimenting with phenomenology

We review the use of introspective and phenomenological methods in experimental settings. We distinguish different senses of introspection, and further distinguish phenomenological method from introspectionist approaches. Two ways of using phenomenology in experimental procedures are identified: first, the neurophenomenological method, proposed by Varela, involves the training of experimental subjects. This approach has been directly and productively incorporated into the protocol of experiments on perception. A second approach may have wider application and does not involve training experimental subjects in phenomenological method. It requires front-loading phenomenological insights into experimental design. A number of experiments employing this approach are reviewed. We conclude with a discussion of the implications for both the cognitive sciences and phenomenology.     

Reduction of the misinformation effect by arousal induced after learning

Misinformation introduced after events have already occurred causes errors in later retrieval. Based on literature showing that arousal induced after learning enhances delayed retrieval, we investigated whether post-learning arousal can reduce the misinformation effect. 251 participants viewed four short film clips, each followed by a retention test, which for some participants included misinformation. Afterward, participants viewed another film clip that was either arousing or neutral. One week later, the arousal group recognized significantly more veridical details and endorsed significantly fewer misinformation items than the neutral group. The findings suggest that arousal induced after learning reduced source confusion, allowing participants to better retrieve accurate details and to better reject misinformation.     

IJPR: beyond the limit and limiting the beyond

It is now almost 20 years since Janicaud’s critique of the ‘theological turn in French phenomenology’ (Janicaud 1991, 2000), with its emphasis on phenomenology and theology as two and never one. Yet since that time there been an explosion of phenomenologies which are, if not overtly, implicitly religious and phenomenology. Thus, we have phenomenologies of prayer, or love, or hope, and the possibilities of further phenomenologies. The challenge of these emerging phenomenologies is that there seems to be no noematic correlate to a noesis in intentionality. To the fore in the reconsideration of this phenomenological challenge is Jean-Luc Marion (although there are others such as Levinas, Jean-Louis Chrétien, and Michel Henry): all aspects of lived experience appear now to belong to the proper scope of phenomenology. Marion considers the relation in Husserl between intentions and intuitions which fulfil these intentions, and suggests a reversal. In Marion, although intentionality is not rejected, the phenomenological flow which the reduction brings to light is from the object as such as it gives itself in intuition, and then from intuition to intention. For Marion, phenomena are saturated—they give too much. Religion becomes a test-case for all phenomenology. This bearing, drawing mainly on The Visible and the Revealed, offers some of the key things in Marion’s phenomenology.
