Argues that the information-processing paradigm can both revitalize so-called strong-effects theories in mass media research and make them more inclusive. Discusses how the four previous studies in this issue show the use of simple solutions to problems that have plagued mass-media-effects research and call out for further inclusion of discussions…

Two accounts explain why studying pictures reduces false memories within the Deese-Roediger-McDermott paradigm (J. Deese, 1959; H. L. Roediger & K. B. McDermott, 1995). The impoverished relational-encoding account suggests that studying pictures interferes with the encoding of relational information, which is the primary basis for false memories…

A study examined the relative contributions of semantic and non-semantic sources of redundancy in printed English, which play a central role in information processing models. Subjects, 40 undergraduate college students, were divided into two groups. One group predicted missing characters using English text, and the second group was required to…

This study investigates attributions based on behavior congruent with situational demands (in-role) and those based on behavior incongruent with situational demands (out-of-role). (Editor)

Designed to minimize information overload in telecommunications systems, the formal model developed in this paper predicts the usefulness of a message based on the available message features, and may be used to rank messages by expected importance or economic worth. The assumptions of binary and two Poisson independent probabilistic distributions…

Location theory was extended into the domain of information-processing firms by attempting to optimally place a federal research and development agency according to its information-processing functions. The techniques used consisted of identifying possible locations within the continental United States, examining the costs of performing the…

This discussion of the information-processing model of learning as it relates to research in educational media traces research in conceptual organization to its beginnings in mathematical models of information-processing; addresses research hypotheses concerning structure and organization, processes and processing systems, and perceptual cues; and…

Experiments dealing with quantification processes in adults were run as part of an attempt to formulate an information processing model of cognitive development. The existence of three quantification operators--subitizing, counting and estimation--was first postulated. Experiments were then designed to refine the parameters which define the…

A reply to a rejoinder in which Pascual-Leone defended his quantitative model of children's information processing capacity. Trabasso focuses on empirical evidence in presenting his reply to this rejoinder. (BD)

Discusses a study which investigated whether a computer simulation model could suggest subroutines that were instructable and whether instruction on these subroutines could facilitate subjects' solutions to the problem task. (JM)

Develops transactional process model of human judgment and information processing that directs attention away from accumulation of information to the needs, motives, and abilities of information user. Argues that model can be used to improve effectiveness of information-based interventions. Discusses two structural aspects of drug use images.…

Concludes that the model of cultural transmission designed by Dobbert et al and described in this journal is a major advance in the field, but that the model will only be fully rounded once they incorporate the processes by which the learner acquires his or her culture. (RDN)

A sophisticated modeling technique which predicts pollutant movement accurately and may aid in the design of new freeways is reported. EXPLOR (Examination of Pollution Levels of Roadways) was developed specifically to predict pollutant concentrations in a milewide corridor traversed by a roadway. (BL)
