Eine Untersuchung zur Entwicklung der mentalen Repräsentation von Zahlen bei Kindern der zweiten Schulklasse anhand der Navon-Aufgabe
… of composite figures (please refer to Navon, 1977). Further on, the Navon task and the achieved score of a test for dyscalculia (Tedi-Math) were correlated and put together with path analysis. To sum up, the results show, that relevant information of the distractor are used for solution …

Investigating the processing style account of the effects of Naval processing on face recognition performance
Engaging in Navon processing prior to face recognition influences recognition performance (Macrae & Lewis, 2002; Perfect, 2003; Weston & Perfect, 2005). Past research has shown that global Navon processing can improve face recognition accuracy whereas local Navon processing impairs it. One …

Featural and holistic processing in facial composite construction: the role of cognitive style and processing sets
… were encoded by individuals, and introduced a Navon (1977) task into the composite construction process using E-FIT. Results showed that the Navon task had an effect on the accuracy of the facial composites that individuals produced which was mediated by the way in which the target face had …

Face off : automatic versus controlled processing: does a shift in processing affect facial recognition?
… recognition rates, much like the manipulated Navon letters do (Perfect, Weston, Dennis, & Snell, 2008), thus providing an alternative explanation for the mechanism underlying the verbal overshadowing effect (Schooler & Engstler-Schooler, 1990).

Working memory, selective visual attention and hierarchical perception
… for the automaticity of working memory. Using Navon stimuli, I explored if and how various types of items held in working memory affect the perception of visual targets non-spatially, at local and global levels in compound letters. The data show that information in working memory biases the …

Perceptual Precedence in Picture Processing
… take place over time. Recent investigations (Navon 1977, 1981) have sug gested that the global aspects of a stimulus are perceived at an earlier stage in the time course of processing than are the local elements of the stimulus. Other studies (Kinchla § Wolfe 1979; Martin 1979; Hoffman 1980) …

Genomic Designation: New kinds of people at the intersection of genetics, medicine and social action
Genetics can do more than predict, explain or help treat medical conditions - it can create new ones. The social sciences have assumed that genetics must work in and through existing categories of human difference in order to inform clinical practice or social mobilization. By contrast, I go beyond …

The Effect of a Mindfulness-Based Intervention on Attention and Cognitive Control as a Function of Smartphone Notifications.
… a computerized task to assess cognitive control (Navon Letter task), while being exposed to smartphone notifications and control sounds. EEG data were recorded continuously during the task. Results indicated that people in the MBI (vs. control) group showed worse cognitive control in terms of both …

Visual attention shifting in autism spectrum disorder
… task with a dimensional shift component and a Navon-type letter task requiring participants to shift attention between global and local levels of a visual stimulus; and (2) to investigate the degree to which deficits in attention shifting as measured by these tasks in ASD as compared to age- …

Can training paradigms enhance global processing style in people with Asperger Syndrome? A randomised experiment
… Training and test materials utilised the Navon Figures, which are large letters (global format e.g., an “H”) made up of smaller letters (local format, e.g., smaller “F’s”). Results: No significant difference between processing styles were found between those with Asperger syndrome and …

Reduced global processing bias in people with a history of mild traumatic brain injury: Grass everywhere and not a field in sight
… investigate this assumption, we employed the Navon task in Chapter 3 to assess whether people with a history of mTBI demonstrated a tendency to prioritize the processing of local details over global information when presented with multiple objects. This task was chosen as it provides a …
