Memory and consciousness: trace distinctiveness in memory retrievals

The aim of this article was to provide experimental evidence that classical dissociation between levels of consciousness associated with memory retrieval (i.e., implicit or explicit) can be explained in terms of task dependency and distinctiveness of traces. In our study phase, we manipulated the level of isolation (partial vs. global) of the memory trace by means of an isolation paradigm (isolated words among non-isolated words). We then tested these two types of isolation in a series of tasks of increasing complexity: a lexical decision task, a recognition task, and a free recall task. The main result of this study was that distinctiveness effects were observed as a function of the type of isolation (level of isolation) and the nature of the task. We concluded that trace distinctiveness improves subsequent access to the trace, while the level of trace distinctiveness also appears to determine the possibility of conscious or explicit retrieval.     

One Conception of Secularism for All? A Comparison of Conceptions of Laïcité among Nonbelievers,Catholics, and Muslims in France

In European countries, a large number of people feel that Islam is incompatible with secularism. France's legal principle of laïcité (a type of state “secularism”) has governed the relationship between religion and society since 1905. However, recent research suggests that there coexist two distinct lay conceptions of laïcité that differ most notably in their tolerance for the presence of religious symbols in public places, one inclusive, the other restrictive. This latter conception appears to target mainly Muslims. The present research examined the lay conceptions of laïcité held by Catholics, Muslims, and nonbelievers. Analyses of participants’ responses (N = 375) to a scale measuring lay beliefs about laïcité confirmed the existence of two distinct lay conceptions of laïcité that differed in the importance given to public expression of religious beliefs, religious neutrality of the state, and equal treatment of different religions. The results also showed that, independent of participants’ religiosity, the restrictive conception was more prevalent among nonbelievers, the two conceptions were equally prevalent among Catholics, and the inclusive conception was more prevalent among Muslims.

Stereotype content of people with acquired brain injury: Warm but incompetent

Since stereotypes about people with acquired brain injury (ABI) can lead to prejudice, studying these stereotypes is highly important. In two studies, we examined these stereotypes both on idiosyncratic dimensions and on the two dimensions of the Stereotype Content Model. Participants completed a specific questionnaire about ABI and warmth and competence questionnaires regarding people with ABI and other social groups. Specific stereotypes about ABI were found to be underpinned by dimensions of “cognitive impairments and ADL limitations,” “catastrophic outcomes,” and “personal and interpersonal development.” Within the model, people with ABI were seen as being warm but incompetent. The ambivalent ABI stereotype could elicit prejudicial attitudes that may impede rehabilitation.     

A kinematic and dynamic comparison of surface and underwater displacement in high level monofin swimming

Fin swimming performance can be divided into underwater and surface water races. World records are about 10% faster for underwater swimming vs. surface swimming, but little is known about the advantage of underwater swimming for monofin swimming. Some authors reported that the air–water interface influences the kinematics and leads to a narrow vertical amplitude of the fin. On the one hand, surface swimming is expected to affect drag parameters (cross-sectional area (S) and active drag (AD)) when compared to underwater swimming. On the other hand, the surface swimming technique may also affect efficiency (η_F). The aim of this study is therefore to evaluate and compare drag parameters and efficiency during underwater and surface swimming. To this end, 12 international level monofin swimmers were measured during both underwater and surface swimming. Kinematic parameters (both dimensional and non-dimensional), η_F (calculated according to the Elongated-Body Theory), and AD (computed with Velocity Perturbation Method) were calculated for an underwater and a surface fin swimming trial, performed at maximal speed. As expected, results showed significantly lower velocities during surface swimming vs. underwater  = 2.5 m s⁻¹ vs.  = 2.36 m s⁻¹, p < .01). Velocities during underwater and surface swimming were strongly correlated (r = .97, p < .01). Underwater swimming was also associated with higher vertical amplitudes of the fin compared to surface swimming ( = 0.55 m vs. ) = 0.46 m, p < .01). Length-specific amplitudes (A_under/L_b) were in the order of 20% during underwater swimming as for undulating fish, and significantly higher than during surface swimming (A_surf/L_b = 17%, p < .01). Efficiency for surface swimming was about 6% lower than for underwater swimming ( = 0.79 vs.  = 0.74, p < .01). This decrease could be associated with an increase in swimming frequency for surface swimming ( = 2.15 Hz vs.  = 2.08 Hz, p < .01). Active drag during surface swimming was about 7% higher than for underwater swimming ( = 78.9 N vs.  = 84.7 N, p < .01). A significantly smaller cross-sectional area for surface swimming ( = 0.053 m² vs.  = 0.044 m², p < .01) and higher drag coefficient for surface swimming ( = 0.47 vs.  = 0.69, p < .01) were measured. Finally, correlation between cross-sectional area and vertical amplitude of the fin was reported for both underwater and surface swimming. These results suggest that the performance improvement during underwater swimming is not only linked to a wave drag reduction effect but also to a specific swimming technique due to the free surface.     

Community psychology,digital technology,and loss: Remembrance activities of young adults who have experienced the death of a close friend

We argue for community psychology to include digital communications technology in research on ways that the social environment shapes fundamental human experiences. We present a qualitative study that examined the narrative accounts of 20 young adults who experienced the death of a close friend to describe both traditional and digital forms of remembrance in coping with loss. Findings suggest that young adults' activities both online and offline were intended to acknowledge the loss, exchange social support, create and sustain memories of their deceased friend, and facilitate continued communication with the deceased. Participants described both costs and benefits to their real and virtual remembrance activities. Findings illustrate ways that the study of digital technology adds to our understanding of grief and bereavement and contributes to dominant cultural narratives about coping with death. Implications of findings for research in community psychology are discussed.
