Approaches to Assessment

We have two Tobii T60XL eyetrackers, which we use to track patterns of attentional allocation, as well as pupil dilation, in studies of information-processing biases.

We have two 32-chanel Biosemi ActiveTwo EEG/ERP systems, which we use to assess event-related potentials relevant to attentional allocation, affective reactivity, and working memory. These systems are also used in studies of resting EEG.

We have five Biopac BioNomadix wireless physiological monitoring systems, which we use to assess heart rate, heart-rate variability, respiration, facial EMG, and electrodermal activity. These are used both in single-subject sessions as well as in studies of parent-child interactions.

We have five Emotiv wireless EEG systems, which we use to assess EEG power (e.g., alpha) in resting EEG as well as EEG synchrony between parents and children during interaction tasks.

We have one Biopac Functional Near Infrared (fNIR) optical brain imaging system, which we use to assess dynamic blood oxygenation changes in prefrontal cortex during cognitive and emotional tasks.

Finally, BMDI staff are certified phlebotomists and collect blood samples from research participants for studies of genetic, epigenetic, cytokine, and hormonal influences on cognition and mood.
