In many cognitive activities the temporary maintenance and manipulation of mental objects is a necessary step in order to reach a cognitive goal. Working memory has been regarded as the process responsable for those cognitive activities. Our researcha ddresses the question: What limits working memorycapacity? A question that still remains controversial (Lewandowsky, Oberauer, & Brown, 2009). In an attemptto answer thisquestion our studies involve experiments on human beings guided by formal theories about the limits of working memory capacity (Oberauer & Kliegl, 2001; Oberauer & Kliegl, 2006). Specifically, we propose that the dynamics between causes of forgetting (e.g., time-related decay, limited resources, and representational interference) and the processes helping the maintenance, and manipulation of the memoranda (e.g., inhibition, attentional control, and processing speed) are the key aspects in understanding the limits of working-memory capacity (Rodríguez-Villagra, Oberauer, Göthe, Kliegl, & Campos-Ramírez, 2012). In addition, our research has taked into account these dynamics in thecontext of individual differences, developmental differences, and aging differences (Rodríguez-Villagra, Göthe, Oberauer, & Kliegl, 2012).
