Effects of canonical color,luminance, and orientation on sustained inattentional blindness for scenes

Whether scene gist perception occurs automatically and unconsciously has been the subject of much debate. In addition to demonstrating a new method that adapts the Mack and Rock (1998) inattentional blindness cross procedure to allow for sustained inattentional blindness over a large number of trials, we report evidence from a series of experiments that shows that canonical scene features reduce inattentional blindness to scenes by facilitating the extraction of scene gist. When attentional demands are high, the combination of canonical color, canonical luminance, and canonical orientation reduces rates of inattentional blindness. However, when attentional demands are reduced, canonical features are independently sufficient to facilitate gist extraction and to capture attention. These results demonstrate that canonical color, canonical luminance, and canonical orientation all contribute to scene gist perception, and that when attentional demands are high, only highly canonical stimuli are sufficient to capture attention.     

Fundamental British values? Possible implications for children’s spirituality

This article argues that the statement of fundamental British values, as introduced in England’s education system in the period 2012–2014, is problematic, not least in relation to children’s spirituality. The context of the introduction of fundamental British values is outlined. The values chosen are more contested than they may seem, being neither fundamental nor distinctively British. How the idea has been conceptualised and implemented has adverse consequences for children’s understanding of identity, especially for some already marginalised groups, and may encourage a limited, superficial view of spiritual, moral, social and cultural development. This risks excluding some groups, especially Muslims, in the current political context, and discouraging open discussion in schools of controversial topics, when such discussion helps to reduce the danger of radicalisation. Consideration of the impact of statements of values, however apparently uncontroversial, must take account of the power of those formulating such statements and the wider context.     

The client,the therapist and the paranormal: a response to the special edition on psychotherapy and the paranormal

Abstract

In this paper, I provide a published paper response to the papers in this special edition on the paranormal and psychotherapy articulated largely from my career as a parapsychologist. In the introduction I note the definitional differences between advocates and counter-advocates in terms of what might be ‘paranormal’, although I argue ultimately that definitional differences aside, the therapist’s relationship with the client’s unusual experiences is critical, taking a phenomenological stance which is echoed by at least two of the papers in the special edition. In broad review, the papers make a variety of welcome contributions; historical individually and small sample phenomenological and also more metaphorically in terms of articulations of the haunting nature of collective and intergenerational trauma in the social and cultural sphere. I review the papers from a parapsychological perspective, considering the evidence drawn from parapsychological studies where it supports or adds to the topics of each paper. In concluding this response, it seems clear that therapists often work from first principles when relating to clients’ anomalous experiences, and that the papers of the special edition each offer practising therapists some important evidential and practical insights into working with client presentations of ostensibly paranormal and anomalous experiences.     

Picture object recognition in an American black bear (<Emphasis Type="Italic">Ursus americanus</Emphasis>)

Many animals have been tested for conceptual discriminations using two-dimensional images as stimuli, and many of these species appear to transfer knowledge from 2D images to analogous real life objects. We tested an American black bear for picture-object recognition using a two alternative forced choice task. She was presented with four unique sets of objects and corresponding pictures. The bear showed generalization from both objects to pictures and pictures to objects; however, her transfer was superior when transferring from real objects to pictures, suggesting that bears can recognize visual features from real objects within photographic images during discriminations.     

Attention training improves aberrant neural dynamics during working memory processing in veterans with PTSD

Posttraumatic stress disorder (PTSD) is associated with executive functioning deficits, including disruptions in working memory (WM). Recent studies suggest that attention training reduces PTSD symptomatology, but the underlying neural mechanisms are unknown. We used high-density magnetoencephalography (MEG) to evaluate whether attention training modulates brain regions serving WM processing in PTSD. Fourteen veterans with PTSD completed a WM task during a 306-sensor MEG recording before and after 8 sessions of attention training treatment. A matched comparison sample of 12 combat-exposed veterans without PTSD completed the same WM task during a single MEG session. To identify the spatiotemporal dynamics, each group’s data were transformed into the time-frequency domain, and significant oscillatory brain responses were imaged using a beamforming approach. All participants exhibited activity in left hemispheric language areas consistent with a verbal WM task. Additionally, veterans with PTSD and combat-exposed healthy controls each exhibited oscillatory responses in right hemispheric homologue regions (e.g., right Broca’s area); however, these responses were in opposite directions. Group differences in oscillatory activity emerged in the theta band (4–8 Hz) during encoding and in the alpha band (9–12 Hz) during maintenance and were significant in right prefrontal and right supramarginal and inferior parietal regions. Importantly, following attention training, these significant group differences were reduced or eliminated. This study provides initial evidence that attention training improves aberrant neural activity in brain networks serving WM processing.
