Stability of attachment representations: the transition to marriage

This study examined the stability of adult attachment representations across the transition to marriage. One hundred fifty-seven couples were assessed using the Adult Attachment Interview (AAI; C. George, N. Kaplan, & M. Main, 1985), the Current Relationship Interview (J. A. Crowell & G. Owens, 1996), and measures describing relationship functioning and life events 3 months prior to their weddings and 18 months into their marriages. The authors tested the hypotheses that attachment classifications are stable and that change is related to experiences in the relationship and/or life events; 78% of the sample received the same primary AAI classification (secure, preoccupied, and dismissing) at both times. Change was toward increased security and was associated with feelings and cognitions about the relationship. Only 46% of participants initially classified as unresolved retained the classification. Stability of the unresolved classification was associated with stressful life events and relationship aggression.     

Assessing secure base behavior in adulthood: development of a measure,links to adult attachment representations,and relations to couples' communication and reports of relationships

A focus on the secure base phenomenon creates a framework for exploring the function of the attachment system in adulthood. Engaged couples (N = 157) were videotaped in a problem-solving interaction and assessed using the Secure Base Scoring System (SBSS), a system based on Ainsworth's analyses of infant-parent secure base use and support. Study 1 showed behavior was significantly related to representations assessed with the Adult Attachment Interview (M. Main & R. Goldwyn, 1994). In Study 2, the interactions were independently scored with the Rapid Marital Interaction Coding System (RMICS; R. E. Heyman & D. Vivian, 1993), a communication-based system. The SBSS predicted relationship variables beyond the RMICS, especially for women. Results indicate that the secure base phenomenon provides a cogent perspective on adult attachment behavior.     

Strategy planning in cats (Felis catus) in a progressive elimination task

Domestic cats (Felis cans) were administered a progressive elimination task in which they had to visit and deplete 3 baited sites. Cats were brought back to the starting point after each visit to any site whether the visit represented a correct or an incorrect choice. The results revealed that cats organized search as a function of the least distance principle whether they had to assess starting point to target distances (Experiment 1, n = 12) or adjacent bowl distances (Experiment 2, n = 12). The results also revealed that the starting point to target distance factor was the most influential in determining the initial choice (Experiment 3, n = 6) and in producing errors. Errors were also linked to the antero-posterior bodily axis of the cat. Results are discussed in terms of the predatory behavior of the cat.     

Neural substrates of impaired categorical perception of phonemes in adult dyslexics: an fMRI study

Phonological developmental dyslexics remain impaired in phonetic categorical perception (CP) even in adulthood. We studied the brain correlates of CP in dyslexics and controls using a block design fMRI protocol and stimuli from an phonetic continuum between natural /Pa/ and /Ta/ syllables. Subjects performed a pseudo-passive listening task which does not imply voluntary categorical judgment. In the control group, categorical deviant stimuli elicited specific activations in the left angular gyrus, the right inferior frontal gyrus and the right superior cingulate cortex. These regions were not activated in the dyslexic group in which activation was observed for acoustic but not phonetic changes in stimuli. Failures to activate key regions for language perception and auditory attention in dyslexic might account for persistent deficits in phonological awareness and reading tasks.

Object features, object locations, and object files: which does selective attention activate and when?

The representation within which attention operates was investigated in 3 experiments. The task was similar to that of R. Egly, J. Driver, and R. D. Rafal (1994). Participants had to detect the presence of a target at 1 of 4 ends of 2 shapes, differing in color and form. A precue appeared at 1 of the 4 possible corners. The 2 shapes occupied either the same or different locations in the cuing and target displays. The results showed that the cued object location was attended whether or not space was task relevant, whereas the cued object features (color and form) were attended only when these were task relevant. Moreover, when object file continuity was maintained through continuous movement, attention was found to follow the cued object file as it moved while also accruing to the cued location.     

Aktueller Stand der Gruppenpsychotherapieforschung

In view of an increasing importance of group therapies and the intention in healthcare politics to support group treatment, it seems appropriate to provide a review of the current research efforts in this field. In this review, several research traditions are described with a clear focus on the effectiveness of group treatment. Both systematic narrative reviews and recent meta-analyses clearly demonstrate that group treatment of various disorders is equally as effective as individual psychotherapy. Besides outcome research there are other developments in the field, such as the improvement of manualized and focused group therapies even outside cognitive behavioral concepts. Studies related to feedback in groups, specific patient characteristics (especially alexithymia and attachment) as well as the construction of new measures seem to be characteristic for group research during recent years. There is still a need for research related to group dynamics and process aspects of small groups as well as the group leaders and their behavior. In total, research on group psychotherapy has clearly progressed, which justifies the support of this treatment setting.     

A shared-memory approach to microprocessor program development

We have developed hardware and software interfaces with which part of a minicomputer’s memory can be shared among its own programs and an Intel 8080 system. Although access to this shared memory is too slow for most real-time operations, the shared area is an excellent buffer for program code to be copied to faster memory for eventual real-time execution. The shared memory can also be used to pass test data between the processors to automate the testing of 8080 program modules.
