Many studies have documented that cognitive performance is often higher among people of the same age who are tested in more recent years, and it is sometimes suggested that this phenomenon will distort the relations between age and cognition in cross-sectional studies. This possibility was examined with data from two large projects involving adults across a wide age range. The results indicated...

The cognitive correlates of anger arousal were investigated in community-based samples of maritally violent (MV), maritally distressed-nonviolent (DNV), and maritally satisfied-nonviolent (SNV) husbands. Participants performed the Articulated Thoughts in Simulated Situations (ATSS) paradigm while listening to anger-arousing audiotapes. Trained raters coded for irrational beliefs, cognitive bias...

Some maladaptive thought processes are characterized by reflexive and habitual patterns of cognitive and emotional reactivity. We review theoretical and empirical work suggesting that mindfulness -a state of nonjudgmental awareness of the present moment -can facilitate the discontinuation of such automatic mental operations. We propose a framework that suggests a series of more specific mechani...

Cognitive Radio Networks have recently attracted attention because of high efficiency and throughput performance. They transmit (1) repetitively collected readings (e.g. monitoring) and (2) highly confidential data (e.g. geometric location). However, the privacy and the authenticity of the transmitted data are major challenges. This paper proposes a novel steganographic technique that guarantee...

Our route choices depend on our own mental map of the city. This assumption, brought from the areas of spatial cognition and cognitive mapping, establishes a distorted graph as the cognitive model that represents our trips. The task of trajectory prediction consists of determining, when a driver is making a trip, which path will be chosen. Our approach consists of transforming the map according...

As people get older, they experience fewer negative emotions. Strategic processes in older adults' emotional attention and memory might play a role in this variation with age. Older adults show more emotionally gratifying memory distortion for past choices and autobiographical information than younger adults do. In addition, when shown stimuli that vary in affective valence, positive items acco...

OBJECTIVE The major cognitive theories of persecutory delusion formation and maintenance are critically examined in this article. METHOD The authors present a comprehensive review of the literature, citing results of relevant functional neuroimaging and neural network studies. RESULTS People with persecutory delusions selectively attend to threatening information, jump to conclusions on the...
