Simulating Local Biases in Visual Attention in Neurocognitive Performance.

Typical visual perception includes an attention bias toward right hemisphere mediated global, holistic cortical processing. An atypically local, detail-oriented focus of attention is characteristic of left hemisphere processing and is often observed in patients whose field of attention is restricted by certain types of neurocognitive impairment. We designed the present pair of studies to induce a local attentional focus to observe its consequences on neurocognitive measures of visuospatial processing. In Experiment I, participants wore glasses mimicking simultanagnosia, a disorder of visual attention, to induce a narrowed, atypical attentional style while they completed visual neuropsychological tasks. This simulation impaired participants' capacities to visually synthesize and efficiently reproduce Complex Figure stimuli as measured with the Boston Qualitative Scoring System (BQSS), and it induced an atypical attentional style on Rorschach Performance Assessment System (R-PAS) responses. In Experiment II, participants wore glasses designed to provoke differential hemispheric activation, also hypothesized to influence style of visual attention; but this manipulation did not influence neurocognitive task performance. We discuss implications for the interpretation of BQSS and R-PAS scores and offer directions for future research.

The Effects of Coding the Location of Individual Objects in a Normative Sample of Rorschach Data.

The locations people use when constructing responses to the Rorschach task demonstrate their style of perceiving the environment. Current systems code location use into three mutually exclusive categories: use of the whole inkblot (W), common detail areas (D), and rare detail areas (Dd). The location of objects within multiobject W responses typically are never classified and those within D areas might or might not be, which could lead to a biased understanding of the visual structure embedded in the task. To better understand this structure, we systematically coded the location of all individual response objects in 145 normative protocols, finding some notable differences relative to conventional coding guidelines. Across cards, from 8% to 71% (M = 40.2%) of W responses had multiple subcomponent objects that typically are never tallied, and multiple unnumbered location areas are used more often than many specific numbered areas. To assess generalizability, we documented correspondence with location frequencies in 4,786 protocols gathered using Rorschach Performance Assessment System guidelines. The results contribute to an improved understanding of the visual structure built into the inkblot stimuli and a method for quantifying exhaustiveness, commonness, and atypicalness as independent dimensions. We discuss implications for coding and interpreting inkblot location use.

Contemporary Data on the Location of Response Objects in Rorschach's Inkblots.

Using a diverse sample of 4,786 protocols obtained with the Rorschach Performance Assessment System (Meyer, Viglione, Mihura, Erard, & Erdberg, 2011), we provide a contemporary overview of how people organize Rorschach's inkblots into identifiable regions while formulating responses. After examining how frequently each location was used across all cards in this sample, we examined the consistency of their use by computing parallel information in 17 samples (N = 4,701) obtained using the Comprehensive System (CS; Exner, 2003), including clinical, nonclinical, and adult, child, and adolescent data. Even though the CS data could only record a single location for each response, the average correlation of location use across samples was .96. The results also document continuous dimensionality in use rather than any discontinuities that would demarcate a boundary between common and uncommon locations. Implications of this notable reproducibility and dimensionality are discussed for future conceptualization of location typicality, including location coding considerations and possibilities for improved measures of perceptual fit.
