Observed bodies generate object-based spatial codes

Contemporary studies of spatial and social cognition frequently use human figures as stimuli. The interpretation of such studies may be complicated by spatial compatibility effects that emerge when researchers employ spatial responses, and participants spontaneously code spatial relationships about an observed body. Yet, the nature of these spatial codes – whether they are location- or object-based, and coded from the perspective of the observer or the figure – has not been determined. Here, we investigated this issue by exploring spatial compatibility effects arising for objects held by a visually presented whole-bodied schematic human figure. In three experiments, participants responded to the colour of the object held in the figure’s left or right hand, using left or right key presses. Left-right compatibility effects were found relative to the participant’s egocentric perspective, rather than the figure’s. These effects occurred even when the figure was rotated by 90 degrees to the left or to the right, and the coloured objects were aligned with the participant’s midline. These findings are consistent with spontaneous spatial coding from the participant’s perspective and relative to the normal upright orientation of the body. This evidence for object-based spatial coding implies that the domain general cognitive mechanisms that result in spatial compatibility effects may contribute to certain spatial perspective-taking and social cognition phenomena.

A Democratic Opening? The AKP and the Kurdish Left

Since its foundation, militant democratic arguments have underpinned an enforced secularism in Turkey. The 2002 election of the AKP, described as a “moderate Islamist party”, has challenged Turkey’s secular identity. In the more than twelve years since the AKP has been in power, Turkey’s political landscape has experienced significant changes, with periods of extensive democratic reforms punctuated by regression in certain areas, notably freedom of expression and the right to protest. State repressive measures coupled with Recep Tayyip Erdoğan’s reluctance to exit the political stage have been the focus of much commentary and analysis. This article argues, however, that under AKP rule the Kurdish issue – critical to ensuring the normalization of politics and democratization in Turkey – has been brought in from the political cold and assesses the creation and role of the HDP (Halkların Demokratik Partisi), a Kurdish political party that is endeavoring to situate itself in the mainstream of Turkey’s political landscape. We posit that the HDP can be viewed as the offspring of this “democratic opening,” a project that was meant to ensure a radical transformation of the Kurdish issue in Turkey. Through analysing the historical trajectory of both AKP and HDP and the militant democratic arguments that led to their predecessors’ exclusion from the public sphere, this article engages with the key question of the extent to which the AKP’s treatment of the Kurdish issue has provided a vehicle for broader democratisation and facilitated a reconsideration of the Kurdish question in Turkey.

Space-related confabulations after right hemisphere damage

Confabulations are usually referred to memory distortions, characterized by the production of verbal statements or actions that are inconsistent with the patient’s history and present situation. However, behavioral patterns reminiscent of memory confabulations can also occur in patients with right hemisphere damage, in relation to their personal, peripersonal or extrapersonal space. Thus, such patients may be unaware of their left hemiplegia and confabulate about it (anosognosia), deny the ownership of their left limbs (somatoparaphrenia), insult and hit them (misoplegia), or experience a “third”, supernumerary left limb. Right brain-damaged patients can also sometimes confabulate about the left, neglected part of images presented in their peripersonal space, or believe to be in another place (reduplicative paramnesia). We review here these instances of confabulation occurring after right hemisphere damage, and propose that they might reflect, at least partially, the attempts of the left hemisphere to make sense of inappropriate input received from the damaged right hemisphere.
