Do remembering and knowing differ qualitatively (reflecting distinct underlying processes) or quantitatively (reflecting different levels of strength)? Broadly speaking, models of remember-know judgments based on these alternatives have been tested by examining the proportion of remember and know responses that are made across conditions or levels of confidence. Here, we consider reaction time ...

Cardiovascular responses occur not only in the immediate presence of stressors, but also while later thinking about those experiences. Evidence suggests that these delayed responses, such as those produced by ruminating about prior angering experiences, may play an important role in the development of cardiovascular disease. We examine whether physiological consequences of rumination depend on ...

than they are in a large number of preadolescent boys. In the course of his clinical examination, it was found that he had fourth-grade proficiency in reading, and that he enjoys reading such books as the "Arabian Nights" for his own amusement. He passed the ten-year reading and reproduction test with one memory to spare, so that he remembers fairly well what he reads. He is a trifle slow in hi...

Violent instances of intergroup conflict in recent memory have usually involved cultural groups, but theory and research on the psychology of intergroup relations is largely culture free. The two most prominent theories, realistic group conflict theory (RGCT) and social identity/self-categorization theory (SIT/SCT) provide fundamental insight into basic processes in intergroup relations: (1) th...

Functional neuroimaging and neuropsychological findings suggest that memory retrieval of common and proper names is subserved by different neuro-functional systems but little is known about the topographic localization of neural generators. In the present study brain electrical activity was recorded with a high density electrode montage in healthy young volunteers during lexical retrieval upon ...

According to common practice and oral tradition, learning verbal materials through song should facilitate word recall. In the present study, we provide evidence against this belief. In Experiment 1, 36 university students, half of them musicians, learned an unfamiliar song in three conditions. In the sung-sung condition, the song to be learned was sung, and the response was sung too. In the sun...

AIMS To validate the accuracy of construction worker recall of task and environment based information; and to evaluate the effect of task recall on estimates of noise exposure. METHODS A cohort of 25 construction workers recorded tasks daily and had dosimetry measurements weekly for six weeks. Worker recall of tasks reported on the daily activity cards was validated with research observations...

diabetes mellitus is accompanied with disturbances in learning, memory, and cognitive skills in the humans and experimental animals. due to the anti-diabetic and antioxidant activity of pelargonidin (pg), this research study was conducted to evaluate the efficacy of chronic oral pg on alleviating learning and memory disturbance in streptozotocin-diabetic rats. male wistar rats were divided into...

BACKGROUND Certain manipulations, such as testing oneself on newly learned word associations (recall), or the act of repeating a word during training (reproduction), can lead to better learning and retention relative to simply providing more exposure to the word (restudy). Such benefit has been observed for written words. Here, we test how these training manipulations affect learning of words p...

Twenty healthy subjects (10 men, 10 women) participated in an EEG study with an extended continuous recognition memory task, in which each of 30 words was randomly shown 10 times and subjects were required to make old vs. new decisions. Both event-related brain potentials (ERPs) and induced band power (IBP) were investigated. We hypothesized that repeated presentations affect recollection rathe...
