Cognitive Information

In the prodromal phase of schizophrenia, severe alterations of the visual appearance of the environment have been found, accompanied by a state of intense anxiety. The present study considers the possibility that these alterations really exist in the appearance of objects, but that healthy people do not see them. The image of the world that we see is continuously deformed and fragmented by foreshortenings, partial overlapping, and so on and must be constantly reassembled and interpreted; otherwise, it could change so much that we would hardly recognize it. Since pleasure has been found to be involved in visual and cognitive information processing, the possibility is considered that anhedonia (the reduction of the ability to feel pleasure) might interfere with the correct reconstruction and interpretation of the image of the environment and alter its appearance. The possibility is also considered that these alterations might make the environment hostile, might at times evoke the sensation of being trapped by a predator, and might be the cause of the anxiety that accompanies them. According to some authors, they might also induce delusional ideas, in an attempt to restore meaning in a world that has become chaotic and frightening.

Cognitive Information

This chapter addresses role of cognitive, information processing and learning mechanisms underlying children’s acquisition of quantifiers in natural language. We discuss the cognitive mechanisms that provide content to quantificational expressions, constraints on possible quantifier meanings, and the role of syntax in identifying a novel word as quantificational. We also examine the syntax and semantics of quantifiers in development, examining interactions between multiple scope bearing expressions in a single sentence. We explore the grammatical and psycholinguistic constraints at play in shaping children’s acquisition and use of quantificational expressions, highlighting factors that can mask children’s competence in this domain.

A mental state has intentional content when it represents features of the world. The intentional content of a belief can be characterized in terms of concepts: the content of the belief that fish swim is characterized by the concept of fish and the concept of swimming. The contents of beliefs are, for this reason, often described as conceptual. One way to explain this idea is to say that to have a belief, one has to possess the concepts which characterize the belief’s content. Another way to explain it is to say that the propositional content of the belief is made up of concepts. Some philosophers believe that certain mental states have non conceptual contents: either in the sense that these states represent the world without the subject having to possess the relevant concepts, or in the sense that their propositional contents are not made up of concepts. The main examples of these putative mental states with nonconceptual contents are conscious perceptual experiences and the nonconscious states of cognitive information-processing systems (such as the visual system).

To say that a mental state has intentional content is to say that it represents features of the world. The intentional content of a belief can be characterized in terms of concepts: the content of the belief that fish swim is characterized by the concepts ‘fish’ and ‘swimming’. The contents of beliefs are, for this reason, often described as conceptual. One way to explain this idea is to say that to have a belief, one has to possess the concepts which characterize the belief’s content. However, some philosophers believe that certain mental states have non-conceptual contents: these states represent the world without the subject having to possess the concepts which characterize their contents. The main examples of these putative states are conscious perceptual experiences and the non-conscious states of cognitive information-processing systems (such as the visual system).

Complex Monitoring

To obtain a more precise understanding of the constructs underlying complex monitoring, measures of short-term memory and visual search were administered to 7 male and 13 female college students. The hypothesis was that more rapid short-term memory and visual search would be related to successful monitoring. A correlational analysis indicated that choice reaction time was related to performance ( r = –.38 and –.43) while rate of serial comparisons was not ( r = –.08 and –.28). It was concluded that information-processing measures enhanced the understanding of the underlying processes in monitoring beyond that provided by traditional cognitive tests.
