Methods for Image-based Surveys of Benthic Macroinvertebrates and Their Habitat Exemplified by the Drop Camera Survey for the Atlantic Sea Scallop N. David Bethoney1, Kevin D. E. Stokesbury1 1School for Marine Science and Technology, University of Massachusetts Dartmouth Image based surveying is an increasingly practical, non-invasive method to sample the marine environment. We present the protocol of a drop camera survey that estimates the abundance and distribution of the Atlantic sea scallop (Placopecten magellanicus). We discuss how this protocol can be generalized for application to other benthic macroinvertebrates.
Central and Divided Visual Field Presentation of Emotional Images to Measure Hemispheric Differences in Motivated Attention Aminda J. O'Hare1, Ruth Ann Atchley2, Keith M. Young3 1Department of Psychology, University of Massachusetts Dartmouth, 2Department of Psychology, University of Kansas, 3Department of Psychology, University of Minnesota Duluth This study compared central versus divided visual field presentations of emotional images to assess differences in motivated attention between the two hemispheres. The late positive potential (LPP) was recorded using electroencephalography (EEG) and event-related potentials (ERPs) methodologies to assess motivated attention.
