Proneness to psychosis and selection of objects of visual attention: individual differences in visual marking

Deficits in early visual attention and perceptual organisation have frequently been shown to associate with both poor pre-morbid schizophrenia and those at a greater putative risk of psychosis. The nature of the deficit is unclear. The present study investigated the relationship between speed of visual marking and proneness to psychosis. 20 males and 20 females completed several tasks assessing speed of selection and de-selection of visual objects. As predicted, negative schizotypy was associated with poorer marking in males, but socially desirable responding potentially confounded this result. In addition, impulsive non-conformity swas associated with poorer visual marking, more prominently in females. These results are discussed in relation to possible mechanisms by which psychosis-proneness and impulsivity may restrict the top–down influences operating on early visual attention.     

Evidence for covert attention switching from eye-movements. Reply to commentaries on Liechty et al., 2003

We argue that our research objectives in Liechty, Pieters, and Wedel (2003) are to provide generalizable insights into covert visual attention to complex, multimodal stimuli in their natural context, through inverse inference from eye-movement data. We discuss the most important issues raised by Feng (2003) and Reichle and Nelson (2003), in particular the task definition, inclusion of ad features, object-based versus space-based attention and the evidence for the where and what streams.Author names are in reverse alphabetical order.     

Parallel patterns of spatial compatibility and spatial congruence…as long as you don't look too closely

The effects of spatial compatibility and spatial congruence have both been explained in terms of a dual-route model under which spatial information about the stimulus, regardless of task relevance, is directly passed from perception to action. Recently, however, some alternatives to the dual-route model of the Simon Effect have been proposed (or re-introduced) as viable explanations. The present experiment compared the magnitudes of the effects of spatial compatibility and spatial congruence across a range of tasks that varied in their dimensional overlap. The results exhibited a remarkable parallel between the two phenomena when viewed only in terms of the interaction between stimulus set and response set. This could be taken as new evidence for a common origin. However, when the entire pattern of results was examined, a large difference between compatibility and congruence were also seen, which implies that there is at least one important difference between the two phenomena.     

Not so fast: Rethinking the effects of action video games on attentional capacity

Considerable excitement has been generated by recent studies showing that video gaming alters fundamental aspects of attention. We tested the claim that people who frequently play action video games (video game players (VGPs)) have a greater capacity of attention than those who rarely play video games (non‐video game players (NVGPs)). We first attempted to replicate previous findings by comparing VGPs and NVGPs on a flanker compatibility task (Experiment 1). In contrast with previous studies, VGPs did not demonstrate greater intrusion from distractors, calling into question the reliability of previous findings. In Experiment 2, we manipulated the eccentricity of flankers in an Eriksen flanker task to examine the extent to which VGPs and NVGPs processed irrelevant peripheral stimuli. No attentional differences emerged in the conditions tested, with both groups displaying compatibility effects at all eccentricities. Together these results raise doubts that video game playing increases attentional capacity.     

Supporting Japanese Mothers of Children with ADHD: Cultural Adaptation of the New Forest Parent Training Programme

International practice guidelines recommend medication and behavioral intervention as evidenced‐based treatments for attention deficit hyperactivity disorder (ADHD). Currently in Japan, the availability of non‐pharmacological interventions for ADHD is limited. We report the results of a pilot and a proof‐of‐concept study for a new behavioral intervention for Japanese mothers of children with ADHD. The pilot study delivered a standard six‐session behavioral intervention and two parent‐support sessions. Participants approved the group format and requested additional support to change parenting practices and behavioral strategies targeting ADHD symptoms. For the proof‐of‐concept study, the intervention was revised to include five sessions of pre‐intervention support followed by six sessions of the New Forest Parent Training Programme (NFPP), an evidence‐based intervention for ADHD. The revised intervention, NFPP‐Japan, was associated with reductions in the mothers’ reports of children's ADHD symptoms and aggression, more effective parenting practices, and reduced parenting stress. The pilot and proof‐of‐concept studies indicate that it is possible to successfully modify Western behavioral interventions for Japanese mothers and to justify a randomized controlled trial evaluation of the NFPP‐Japan, which is currently underway.     

Visual orienting and attention deficits in 5- and 10-month-old preterm infants

Cognitive outcomes for children born prematurely are well characterized, including increased risk for deficits in memory, attention, processing speed, and executive function. However, little is known about deficits that appear within the first 12 months, and how these early deficits contribute to later outcomes. To probe for functional deficits in visual attention, preterm and full-term infants were tested at 5 and 10 months with the Infant Orienting With Attention task (IOWA; Ross-Sheehy, Schneegans and Spencer, 2015). 5-month-old preterm infants showed significant deficits in orienting speed and task related error. However, 10-month-old preterm infants showed only selective deficits in spatial attention, particularly reflexive orienting responses, and responses that required some inhibition. These emergent deficits in spatial attention suggest preterm differences may be related to altered postnatal developmental trajectories. Moreover, we found no evidence of a dose-response relation between increased gestational risk and spatial attention. These results highlight the critical role of postnatal visual experience, and suggest that visual orienting may be a sensitive measure of attentional delay. Results reported here both inform current theoretical models of early perceptual/cognitive development, and future intervention efforts.     

Threat captures attention but does not affect learning of contextual regularities

Some of the stimulus features that guide visual attention are abstract properties of objects such as potential threat to one's survival, whereas others are complex configurations such as visual contexts that are learned through past experiences. The present study investigated the two functions that guide visual attention, threat detection and learning of contextual regularities, in visual search. Search arrays contained images of threat and non-threat objects, and their locations were fixed on some trials but random on other trials. Although they were irrelevant to the visual search task, threat objects facilitated attention capture and impaired attention disengagement. Search time improved for fixed configurations more than for random configurations, reflecting learning of visual contexts. Nevertheless, threat detection had little influence on learning of the contextual regularities. The results suggest that factors guiding visual attention are different from factors that influence learning to guide visual attention.     

Identification of emotional expressiveness in facial photographs over 36 h of extended vigilance in healthy young men—a preliminary study

Changes in sleep patterns negatively influence some emotional responses, but their effects on facial expressiveness identification are unclear. To investigate these effects, 21 young, healthy, male volunteers of intermediate chronotype evaluated emotional expressiveness of faces depicting 6 basic emotions in 5 emotional gradients every 4?h over 36?h of continuous wakefulness. To measure attention and mood we used the Psychomotor Vigilance test and the Positive and Negative Affect Schedule Expanded, respectively. We found effects of emotional gradient for all types of emotions (100%?>?80%?>?60%?>?40%?>?20%) during all tested periods, with no indications of circadian effects. The only emotional rating to be affected was disgust, which was progressively blunted throughout the experiment. This effect did not parallel homeostatic and circadian changes in mood, alertness or attention. We conclude that identifying disgust on facial photographs is particularly sensitive to lack of sleep irrespective of sleep-induced changes in mood and attention in males.
