Modulation of LIP activity by predictive auditory and visual cues

by Yale E. Cohen, Ian S. Cohen, Gordon W. Gifford Iii - Cerebral Cortex , 2004
"... The lateral intraparietal area (area LIP) contains a multimodal repre-sentation of extra-personal space. To further examine this represen-tation, we trained rhesus monkeys on the predictive-cueing task. During this task, monkeys shifted their gaze to a visual target whose location was predicted by t ..."

Schema abstraction‖ in a multiple-trace memory model

by Douglas L. Hintzman - Psychological Review , 1986
"... A simulation model of episodic memory, MINERVA 2, is applied to the learning of concepts, as represented bythe schema-abstraction task. The model assumes that each experience produces a separate memory trace and that knowledge of abstract oncepts i derived from the pool of episodic traces at the tim ..."

Component processes in task switching

by Nachshon Meiran, Ziv Chorev, Ayelet Sapir - Cognitive Psychology , 2000
"... Participants switched between two randomly ordered, two-choice reaction-time (RT) tasks, where an instructional cue preceded the target stimulus and indicated which task to execute. Task-switching cost dissipated passively while the partici-pants waited for the instructional cue in order to know whi ..."

Memory for goals: an activation-based model

by Erik M. Altmann , J. Gregory Trafton , 2002
"... Goal-directed cognition is often discussed in terms of specialized memory structures like the "goal stack." The goal-activation model presented here analyzes goal-directed cognition in terms of the general memory constructs of activation and associative priming. The model embodies three pr ..."

predictive constraints: (1) the interference level, which arises from residual memory for old goals; (1) the strengthening constraint, which makes predictions about time to encode a new goal; and (3) the priming constraint, which makes predictions about the role of cues in retrieving pending goals

Behavioral theories and the neurophysiology of reward,

by Wolfram Schultz - Annu. Rev. Psychol. , 2006
"... ■ Abstract The functions of rewards are based primarily on their effects on behavior and are less directly governed by the physics and chemistry of input events as in sensory systems. Therefore, the investigation of neural mechanisms underlying reward functions requires behavioral theories that can ..."

-calculated decision of a barge captain on how to get the most out of his money and time. The performance in these tasks is managed by the brain, which assesses the values and uncertainties of predictable outcomes (sausage, ale, wine, lock pricing, and access to resources) and directs the individuals' decisions

Conjunctive Representations in Learning and Memory: Principles of Cortical and Hippocampal Function

by Randall C. O'Reilly, Jerry W. Rudy - PSYCHOLOGICAL REVIEW , 2001
"... We present a theoretical framework for understanding the roles of the hippocampus and neocortex in learning and memory. This framework incorporates a theme found in many theories of hippocampal function, that the hippocampus is responsible for developing conjunctive representations binding together ..."

stimulus elements into a unitary rep- resentation that can later be recalled from partial input cues. This idea appears problematic, however, because it is contradicted by the fact that hippocampally lesioned rats can learn nonlinear discrimination problems that require conjunctive representations. Our

Predicting retweet count using visual cues

by Ethem F. Can, Hüseyin Oktay, R. Manmatha - in Proceedings of ACM International Conference on information and knowledge management (CIKM , 2013
"... Social media platforms allow rapid information diffusion, and serve as a source of information to many of the users. Particularly, in Twitter information provided by tweets dif-fuses over the users through retweets. Hence, being able to predict the retweet count of a given tweet is important for und ..."

for understanding and controlling information diffusion on Twitter. Since the length of a tweet is limited to 140 char-acters, extracting relevant features to predict the retweet count is a challenging task. However, visual features of im-ages linked in tweets may provide predictive features. In this study, we

An Activation-Based Model of Sentence Processing as Skilled Memory Retrieval

by Richard L. Lewis , Shravan Vasishth , 2005
"... We present a detailed process theory of the moment-by-moment working-memory retrievals and associated control structure that subserve sentence comprehension. The theory is derived from the application of independently motivated principles of memory and cognitive skill to the specialized task of sent ..."

Predicting grammatical classes from phonological cues: An empirical test

by Gert Durieux, Steven Gillis - In J. Weissenborn & B. Höhle (Eds.), Approaches to bootstrapping , 2001
"... This paper investigates to what extent the grammatical class(es) of a word can be predicted on the basis of phonological and prosodic information only. We report on several experiments with an artificial learning system which has to assign English wordforms to their appropriate grammatical class, us ..."

, using various types of phonological and prosodic information. First of all, we examine several phonological cues which were claimed by Kelly (1996) to be particularly good for distinguishing English nouns from verbs. Our results indicate that these cues are indeed partially predictive for the problem

Temporal structure in neuronal activity during working memory in macaque parietal cortex,”

by Bijan Pesaran , John S Pezaris , Maneesh Sahani , Partha P Mitra , Richard A Andersen - Nature Neuroscience, , 2002
"... The neural basis of working memory is typically studied in non-human primates by recording activity during delayed response tasks 1 . Cue-selective elevations in mean firing rates are found during the delay period in many brain areas using different versions of these tasks Temporally correlated ne ..."
