Deconstructing the manifest dream

A major part of the analyst's task is to discover the basis for the patient's misidentification of his present life situation with significant but threatening events of his earlier life, now repressed and inaccessible to conscious recall. Reconstructing the patient's history is a crucial step in this process of discovery, but the dynamic relation between the present and the past must be reconstructed as well. The structure of the manifest dream contains the key to this relation. The imagery of the dream is a composite of experimental materials drawn from important drive-related events of the present and the past. The complex formed by the manifest dream and the patient's associations provides the analyst with data about both of these distinct sets of drive-related experiences. As Freud's discussion of his M elusine dream illustrates, one associative thread can be traced to an experience that incorporates a conflicted current wish. Another thread will lead to an experience in which a repressed wish of childhood has been expressed. Where the two associative threads converge, in the composite imagery of the dream, the basis for the identification between the wishes of the present and the past will be exposed. An understanding of the structure of the manifest dream helps to clarify some of the important theoretical issues left unresolved in Freud's writings. These include: the function of the day residue and the mechanism through which it is formed, the relation of the screen memory to the associative process, and the differing roles of condensation and displacement in dream construction and free association. A simple procedure is described for enhancing the recovery of the significant childhood memories whose details have been incorporated into the composite imagery of the manifest dream.     

Induction by reinforcer schedules.

Traditional strategies for determining whether a reinforcer schedule enhances the occurrence of an activity are reviewed and critically evaluated. A basic assumption underlying these strategies is that it is possible to isolate the effect of reinforcer intermittency on schedule induction. It is concluded that this is not, in fact, possible. An alternative approach is proposed that emphasizes the inductive effects of the reinforcer schedule as a unit and the effects of particular aspects of the reinforcer schedule (e.g., interreinforcer interval, repetition of the reinforcer, reinforcer magnitude).     

The experimental analysis of agoraphobia

A concerted move towards the use of experimental analyses is proposed. It is suggested that our understanding of agoraphobia can best be advanced by taking this step. The argument in support of such a move is illustrated and developed in respect of the role of safety signals in maintaining and influencing agoraphobic behaviour. A detailed analysis is given of the factors postulated to determine the strength of safety signals, and the complex inter-relations between fear and safety are examined.     

Relaxation-induced anxiety: mechanisms and theoretical implications

Literature evidence documenting the occurrence of relaxation-induced anxiety is reviewed, and several hypothesized mechanisms to explain the phenomenon are discussed. Possible avenues for circumventing the problem in therapy are offered. Finally, a theoretical model is presented wherein the phenomenon is viewed with a broader framework designed to explain the development and maintenance of the more generalized anxiety disorders. That framework emphasizes the emergence of fear of somatic anxiety cues and fear of loss of control from more fundamental interpersonal anxieties.     

Time course of visual information utilization during fixations in reading

College students read short texts from a cathode-ray tube as their eye movements were being monitored. During selected fixations, the text was briefly masked and then it reappeared with one word changed. Subjects often were unaware that the word had changed. Sometimes they reported seeing the first presented word, sometimes the second presented word, and sometimes both. When only one word was reported, two factors were found to determine which one it was: the length of time a word was present during the fixation and the predictability of a word in its context. The results suggested that visual information is utilized for reading at a crucial period during the fixation and that this crucial period can occur at different times on different fixations. The pattern of responses suggested that the first letter of a word is not utilized before other letters and that letters are not scanned from left to right during a fixation.     

Retrieval inhibition from part-set cuing: A persisting enigma in memory research

When people are asked to recall words from a list they have just studied or to produce as many items as possible from a well-known category (e.g., states of the United States), having available a subset of the items as cues often does not facilitate retrieval of the remaining items and sometimes inhibits it. The finding has been obtained many times with a variety of experimental tasks including recall from categorized and noncategorized lists and retrieval from very long-term memory. This paper reviews the studies that have yielded the effect, and considers several explanations of it that have been proposed. None of these explanations is viewed to be entirely adequate and compelling.
