Does physical pain impair abstract thinking?

The ability to think abstractly constitutes a fundamental dimension of human cognition. Although abstraction has been extensively studied, its emotional and affective antecedents have been largely overlooked. One experiment was conducted to examine whether physical pain affects abstraction. Drawing on Construal Level Theory [Trope, Y., &; Liberman, N. (2010). Construal-level theory of psychological distance. Psychological Review, 117, 440–463] and Loewenstein’s [(1996). Out of control: Visceral influences on behavior. Organizational Behavior and Human Decision Processes, 65, 272–292] visceral factors theory, we hypothesised that pain impairs abstraction because pain constricts people’s mental horizons and lead to a concrete, inward-focus toward oneself in the here and now. Physical pain was manipulated between subjects (N?=?150). The participants either kept their left hand immersed in cold (painful) water or neutral (painless) water while we measured abstract versus concrete behaviour identification, categorisation, and perceptual processing. Bayesian statistical analyses indicate substantial evidence against the hypothesis that pain impairs abstraction. In contrast to many other previously studied cognitive outcomes (e.g. attention), abstraction appears to be largely immune to acute, experimentally induced pain.     

Describing scenes hardly seen

Knowledge about scene categories, the so-called gist, can be extracted very rapidly, while recognition and naming of individual scene objects is a more effortful process. We investigate this phenomenon by presenting action scenes involving two actors for durations varying between 100 and 300 ms. Incoherence was created by mirroring individual scene actors. Upon masked presentation participants had to report content, actors and objects and to indicate whether the scene was meaningful or not. Scene coherence was judged correctly at all presentation durations. Actors were correctly identified in about one-third of the cases even with presentation durations of 100 ms, and identification rate increased up to 80% with longer durations. Identification depended on scene coherence, on the position of agents in the scene, and on the position of actors relative to the fixation cross. These interdependencies of scene and object perception indicate that the visual system seems to be very sensitive to meaningful interactions of living entities. A series of fixations is not necessary to identify actors of a scene.     

Beyond the forest and the trees: local and global interference in hierarchical visual stimuli containing three levels

Our visual world can be thought of as organised in a hierarchical manner. Studies on hierarchical letter stimuli (a large letter composed of smaller letters) suggest that processing of a visual scene is global to local, a phenomenon known as the global-precedence effect. Elaborating on this global-to-local hypothesis we tested whether global interference will increase with increasing level of globality. For this, we used three-level hierarchical letter stimuli with a global, middle, and local level. When attending to the local level of the stimulus, only the middle level showed an interference effect, whereas the global level did not interfere at all. We argue that, considering the perceptual and attentional contributions to this effect, the hypothesis of global-to-local processing of a visual scene may only hold within a limited spatial attentional window.
