Studying visual attention using the multiple object tracking paradigm: A tutorial review

Human observers are capable of tracking multiple objects among identical distractors based only on their spatiotemporal information. Since the first report of this ability in the seminal work of Pylyshyn and Storm (1988, Spatial Vision, 3, 179–197), multiple object tracking has attracted many researchers. A reason for this is that it is commonly argued that the attentional processes studied with the multiple object paradigm apparently match the attentional processing during real-world tasks such as driving or team sports. We argue that multiple object tracking provides a good mean to study the broader topic of continuous and dynamic visual attention. Indeed, several (partially contradicting) theories of attentive tracking have been proposed within the almost 30 years since its first report, and a large body of research has been conducted to test these theories. With regard to the richness and diversity of this literature, the aim of this tutorial review is to provide researchers who are new in the field of multiple object tracking with an overview over the multiple object tracking paradigm, its basic manipulations, as well as links to other paradigms investigating visual attention and working memory. Further, we aim at reviewing current theories of tracking as well as their empirical evidence. Finally, we review the state of the art in the most prominent research fields of multiple object tracking and how this research has helped to understand visual attention in dynamic settings.     

Consolidation,wider reflection,and policy: Response to ‘Super‐recognisers: From the lab to the world and back again’

Here, David Robertson and Markus Bindemann respond to a recent BJP Target Article on ‘super‐recognisers’ (SRs). They outline the need to consider human factors that could influence SR performance after selection and the need for a co‐ordinated effort to ensure best practice in the implementation of SRs in applied contexts.     

Moving arms: the effects of sensorimotor information on the problem-solving process

Embodied cognition postulates a bi-directional link between the human body and its cognitive functions. Whether this holds for higher cognitive functions such as problem solving is unknown. We predicted that arm movement manipulations performed by the participants could affect the problem-solving solutions. We tested this prediction in quantitative reasoning tasks that allowed two solutions to each problem (addition or subtraction). In two studies with healthy adults (N?=?53 and N?=?50), we found an effect of problem-congruent movements on problem solutions. Consistent with embodied cognition, sensorimotor information gained via right or left arm movements affects the solution in different types of problem-solving tasks.     

Framingham vascular age is associated with worse cognitive performance in the middle-aged and elderly

“Normal” age-related cognitive decline has been associated with cardiovascular risk factors. Framingham Vascular Age is age-normed cardiovascular risk which may help communicate risk to patients and identify those at relatively higher risk. We aim to assess the association between Framingham Vascular Age and cognition. 346 “healthy” participants (57±10 years) without neuropsychiatric disorders or clinical manifestations of cardiovascular disease were studied. Cognition was evaluated using the Brief Memory and Executive Test and Framingham Vascular Age was calculated. The association between Framingham Vascular Age and cognitive performance was determined through General Linear Models to control for covariates. Framingham Vascular age was associated with poorer Memory and Executive Function/Processing Speed indices (p= 0.019 and p<0.001, respectively). We conclude Framingham Vascular Age is associated with worse Executive Function/Processing Speed and Memory. Vascular Age may help identify patients at higher risk of age-related cognitive decline with implications for communicating the morbidity associated with cardiovascular risk.     

What Determines Social Control? People's Reactions to Counternormative Behaviors in Urban Environments1

Social control refers to any reaction by which a bystander communicates to the “perpetrator” of an uncivil behavior that his or her action is not acceptable. In 3 field studies, we examined the factors that affect people's tendency to exert social control. Passersby in the streets were asked how they would react were they to witness different uncivil behaviors. They also rated their appraisal of the situation and the emotions they would feel. The results suggest that 3 factors are primary determinants of social control: the feeling of responsibility to exert it; the perceived legitimacy of social control in the situation; and the extent to which bystanders felt hostile emotions. These results have implications for how to reduce uncivil behaviors.     

Rooting for (and Then Abandoning) the Underdog

Although people prefer to associate with winners, there is also a strong desire to support the lovable loser or underdog. In 4 studies, we demonstrate the underdog effect and its delimiting conditions. In Studies 1 and 2, participants rooted for the underdog in judgments of athletic, business, and artistic competition. In Study 3, participants watched animated clips of struggling and nonstruggling geometric shapes. The results showed that participants showed more rooting, sympathy, and identification with struggling shapes than with nonstruggling ones. Study 4 identified conditions under which people abandon the underdog, showing that participants rooted for the underdog only when both self‐relevance and consequences were high. Theoretical implications of these findings are discussed.     

The role of sleep-related beliefs to improvement in early cognitive behavioral therapy for insomnia

The aim of this investigation was to examine whether sleep-related beliefs, and reductions in such beliefs and attitudes, were related to clinical improvements in sleep and daytime symptoms after cognitive behavioral therapy (CBT). In total, 64 patients with a short history of insomnia (3-12 months) who had participated in a randomized controlled trial with a 1-year follow-up and received CBT were included. With stepwise multiple regression analyses, sleep-related beliefs were linked to clinical improvements in sleep (five outcomes) and daytime symptoms (seven outcomes). Results indicated that sleep-related beliefs played a small predictive role in clinical improvements in sleep and daytime symptoms after CBT group treatment. Sleep-related beliefs were predictive of treatment response only with regard to sleep efficiency and sleepiness. Reductions in sleep-related beliefs were, however, differently related to improvements in sleep and daytime symptoms. Reductions in such beliefs were consistently linked to improvements in daytime symptoms (7-14% of the variance) but not to sleep improvements (except for sleep quality). In all, this might suggest that sleep-related beliefs play a slightly different role in insomnia than previously envisioned.
