The development of attention to simple and complex visual stimuli in infants: Behavioral and psychophysiological measures

The study of visual attention in infants has used presentation of single simple stimuli, multi-dimensional stimuli, and complex dynamic video presentations. There are both continuities and discontinuities in the findings on attention and attentiveness to stimulus complexity. A continuity is a pattern of looking that is found in the early part of infancy that remains throughout adulthood. A discontinuity is an emerging sensitivity to the content of the information in the stimulus presentations and alterations in patterns of attention based upon stimulus comprehensibility. The current paper reviews some of these findings with particular application to complex video presentations.     

Predicting and manipulating the incidence of inattentional blindness

Inattentional blindness (IB) occurs when an observer, who is engaged in a resource-consuming task, fails to notice an unexpected although salient stimulus appearing in their visual field. The incidence of IB is affected by changes in stimulus-driven properties, but little research has examined individual differences in IB propensity. We examine working memory capacity (WMC), processing styles (flicker task), inhibition (Stroop task), and training in predicting IB. WMC is associated with IB (Experiments 1 and 2) but neither processing style (Experiment 1) nor inhibition (Experiment 2) was associated. In Experiment 2, prior training on a task reduced the incidence of IB compared to no prior training, and this effect was significantly larger when trained on the same tracking task as that used in the IB task rather than a different task. We conclude that IB is related to WMC and that training can influence the incidence of IB.     

Serum lipids and their relationships with hostility and angry affect and behaviors in men.

Research into the relationship between the Type A behavior pattern and coronary heart disease suggests that the anger-hostility-aggression (AHA!) syndrome is directly related to total serum cholesterol and low-density lipoproteins. The present study involved an investigation of the specific components of the AHA! syndrome related to blood lipid levels in 98 healthy men. The disposition to experience and express anger when frustrated, criticized, or treated unfairly (angry reaction, a component of trait anger) was related to total serum cholesterol and to low-density lipoprotein levels. Age and diet also predicted levels of these lipids, but each was unrelated to angry reaction. These results suggest that in healthy men, the experience of strong angry affect in reaction to perceived rejection, criticism, or unfair treatment may be health-toxic because of its relationship to elevated unfavorable serum lipids.     

Development of infant sustained attention and its relation to EEG oscillations: an EEG and cortical source analysis study

The current study examined the relation between infant sustained attention and infant EEG oscillations. Fifty‐nine infants were tested at 6 (N = 15), 8 (N = 17), 10 (N = 14), and 12 (N = 13) months. Three attention phases, stimulus orienting, sustained attention, and attention termination, were defined based on infants' heart rate changes. Frequency analysis using simultaneously recorded EEG focused on infant theta (2–6 Hz), alpha (6–9 Hz), and beta (9–14 Hz) rhythms. Cortical source analysis of EEG oscillations was conducted with realistic infant MRI models. Theta synchronization was found over fontal pole, temporal, and parietal electrodes during infant sustained attention for 10 and 12 months. Alpha desynchronization was found over frontal, central and parietal electrodes during sustained attention. This alpha effect started to emerge at 10 months and became well established by 12 months. No difference was found for the beta rhythm between different attention phases. The theta synchronization effect was localized to the orbital frontal, temporal pole, and ventral temporal areas. The alpha desynchronization effect was localized to the brain regions composing the default mode network including the posterior cingulate cortex and precuneus, medial prefrontal cortex, and inferior parietal gyrus. The alpha desynchronization effect was also localized to the pre‐ and post‐central gyri. The present study demonstrates a connection between infant sustained attention and EEG oscillatory activities.     

Cognitive penetrability,context, and aesthetics: Nanay and Danto on the Gallery of Indiscernibles

Nanay has recently argued, on the basis of the cognitive penetrability of experience, that the attribution of aesthetically relevant properties (ARPs) supervenes on perceptual experience. I argue that this claim is false as stated and cannot be salvaged. I provide a series of thought experiments as counterexamples, showing that the title of an artwork can influence its ARPs, its meaning or value, and the accurate attributions of ARPs while the character of the perceptual experience of the piece remains constant. I introduce the notions of context and appropriate context, and I argue that ARPs supervene on observable properties and appropriate contexts; there is no difference in ARPs without a difference in appropriate context or a difference in observable properties. Two paintings may share all of their observable properties and all of their context-relative perceptual properties but be ARP distinct, since each has a different appropriate context, and contexts are not usually determined or instantiated by perceptual properties.

Profiles in Problem Solving: Psychological Well-Being and Distress Among Persons with Diabetes Mellitus

Although social problem-solving abilities have been consistently associated with indicators of behavioral health, this work has been largely confined to tests of specific theoretical issues. Research has yet to demonstrate how the separate elements of the social problem-solving model relate to different patterns of adjustment, particularly among persons who live with chronic disease. We studied the occurrence of different profiles of social problem-solving abilities observed among persons living with diabetes mellitus. We then examined differences between clusters on measures of life satisfaction and depression. Results indicate that distinct profiles in problem-solving abilities do occur and these groupings can be distinguished by their different patterns of adjustment. Implications for theoretical models of problem solving and clinical assessment and interventions for persons with diabetes are discussed.
