Luck and Vogel (1997) showed that the storage capacity of visual working memory is about four objects and that this capacity does not depend on the number of features making up the objects. Thus, visual working memory seems to process integrated objects rather than individual features, just as verbal working memory handles higher-order "chunks" instead of(More)
In this case study, 14 witnesses of an armed robbery were interviewed after 3 months. Security camera recordings were used to assess memory accuracy. Of all information that could be remembered about 84% was correct. Although accurately recalled information had a higher confidence level on average than inaccurately recalled information, the mean(More)
If 2 words are presented successively within 500 ms, subjects often miss the 2nd word. This attentional blink reflects a limited capacity to attend to incoming information. Memory effects were studied for words that fell within an attentional blink. Unrelated words were presented in a modified rapid serial visual presentation task at varying stimulus-onset(More)
Working memory (WM), including a 'central executive', is used to guide behavior by internal goals or intentions. We suggest that WM is best described as a set of three interdependent functions which are implemented in the prefrontal cortex (PFC). These functions are maintenance, control of attention and integration. A model for the maintenance function is(More)
The authors discuss some problems in learning networks. They propose a new learning procedure, CALM (Categorizing And Learning Module). CALM uses pairs of excitatory representation nodes and inhibitory veto nodes, bound together in a modular structure with an arousal node. Learning in the module is enhanced by a nonspecific external node connected to the(More)
We used the terrorist attacks on September 11, 2001 to investigate if the formation, confidence, and nature of flashbulb memories were dependent on age. In addition, we compared the consistency over time of flashbulb memories with event memory, i.e., widely publicized factual details of the event, in a group of young respondents. College students (n=34, M(More)
