Is the emotional modulation of the attentional blink driven by response bias?

Several studies have shown that the attentional blink (AB; Raymond, Shapiro, & Arnell, 1992) is diminished for highly arousing T2 stimuli (e.g., Anderson, 2005). Whereas this effect is most often interpreted as evidence for a more efficient processing of arousing information, it could be due also to a bias to report more arousing stimuli than neutral stimuli. We introduce a paradigm that allows one to control for such a response bias. Using this paradigm, we obtained evidence that the diminished AB for taboo words cannot be explained by a response bias. This supports the idea that the emotional modulation of the AB is caused by attentional processes.     

A Picture-Based Activity Schedule Intervention to Teach Adults with Mild Intellectual Disability to Use an iPad During a Leisure Activity

Individuals with developmental disabilities have limited opportunities to participate in leisure activities, frequently due to lack of skills. The purpose of the current study was to teach three adults diagnosed with mild intellectual disability to use an iPad in the context of playing the video game Angry Birds. We used an adapted multiple baseline across participants research design to teach the task, which included opening the cover of the iPad, unlocking the device, opening Angry Birds, playing the game, and putting the iPad away. Instruction took place during breaks in a private room at a sheltered workshop. During intervention, participants had access to an activity schedule to aid in completion of the task. In some cases, extra prompts were provided to increase attention to the activity schedule. All three participants showed improvement in the target skill with intervention and gains were sustained during the maintenance phase.     

The need for public policies to promote healthier food consumption: A comment on Wansink and Chandon (2014)

Current approaches to addressing obesity have fallen short. This is largely due to the many environmental forces that undermine people's self-regulatory capacity to be personally responsible for their food choices. Novel insights from the social sciences are needed to inform voluntary, health-promoting actions by companies, institutions, and citizens as well as the design of public health policies. Voluntary interventions that rely on nudges should complement traditional public health strategies such as taxation and restriction of child-targeted marketing in schools. In this commentary, we discuss four food policy issues that would benefit from consumer psychology research: (a) the restriction of food marketing to children, (b) provision of nutrition information through food labels, (c) improving school food environments, and (d) placing limits on portion sizes. Identifying effective solutions for obesity will require approaches that integrate psychological, public health, and legal perspectives and methods.     

Integration of visuospatial information encoded from different viewpoints

Two experiments investigated whether separate sets of objects viewed in the same environment but from different views were encoded as a single integrated representation or maintained as distinct representations. Participants viewed two circular layouts of objects that were placed around them in a round (Experiment 1) or a square (Experiment 2) room and were later tested on perspective-taking trials requiring retrieval of either one layout (within-layout trials) or both layouts (between-layout trials). Results from Experiment 1 indicated that participants did not integrate the two layouts into a single representation. Imagined perspective taking was more efficient on within- than on between-layout trials. Furthermore, performance for within-layout trials was best from the perspective that each layout was studied. Results from Experiment 2 indicated that the stable environmental reference frame provided by the square room caused many, but not all, participants to integrate all locations within a common representation. Participants who integrated performed equally well for within-layout and between-layout judgments and also represented both layouts using a common reference frame. Overall, these findings highlight the flexibility of organizing information in spatial memory.     

How memory mechanisms are a key component in the guidance of our eye movements: Evidence from the global effect

Investigating eye movements has been a promising approach to uncover the role of visual working memory in early attentional processes. Prior research has already demonstrated that eye movements in search tasks are more easily drawn toward stimuli that show similarities to working memory content, as compared with neutral stimuli. Previous saccade tasks, however, have always required a selection process, thereby automatically recruiting working memory. The present study was an attempt to confirm the role of working memory in oculomotor selection in an unbiased saccade task that rendered memory mechanisms irrelevant. Participants executed a saccade in a display with two elements, without any instruction to aim for one particular element. The results show that when two objects appear simultaneously, a working memory match attracts the first saccade more profoundly than do mismatch objects, an effect that was present throughout the saccade latency distribution. These findings demonstrate that memory plays a fundamental biasing role in the earliest competitive processes in the selection of visual objects, even when working memory is not recruited during selection.
