Genetic Testing Considerations in Breast Cancer Patients

Genetic testing is now feasible for a growing number of cancers. Although the implications for unaffected relatives have been widely described, the impact of the tests on affected individuals are often not recognized. We present and discuss four cases that highlight some of the issues—for example, feelings of guilt and anxiety, intrafamilial conflict, and support needs—that may arise in testing affected individuals. We offer some suggestions to aid in the approach to such testing.

Size and distance judgements in the vertical plane under water

Summary Experiments with subjects of varied diving experience in clear water of Malta showed that divers tend to underestimate the distance of the surface more than that of the seabed. The underestimation is most marked in clear empty water, but disappears with practice. Objects viewed vertically downwards tend to be correctly estimated in size; but this is an underestimate in comparison with the overestimation which normally occurs with horizontal viewing. These effects are similar to the moon illusion, but are probably due to visual rather than proprioceptive changes in the vertical plane.

Résumé Des expériences faites avec des sujets possédant divers niveaux d'expérience de plonger en eau claire devant Malte ont montré ques les plongeurs ont tendance à sous-estimer léloignement de la surface plus que du fond de la mer. Cette sous-estimation se révèle la plus marquée en eau claire et vide, mais disparaît avec l'habitude. Des objets regardés verticalement en bas ont tendance à être estimés justement en grandeur; mais c'est là une sous-estimation en comparaison avec la surestimation qui se produit quand ils sont regardés horizontalement. Ces effets sont semblables à la lune-illusion, mais ont probablement pour cause des changements plutôt visuels que proprioceptifs dans le plan vertical.

     

The therapist's poetry as a therapeutic incident

Poetry can be understood as an intrapsychic record of introspection, and as a means for interpretation in the therapeutic situation. In this installment (the second of a series to be eventually published at book-length) the authors examine from their personal research the uses, as well as dangers, of utilizing poetry in therapy. Poetry should not be used as a gimmick to direct the process of therapy, but as a point of spontaneous interaction, insight, and empathy. Used appropriately, poetry may bring to the client and to the therapist insight and meaning. The therapist may also use his or her own poetry as a creative means for recognizing countertransference in the therapeutic setting.Dr. Moss is an Episcopal Priest and the Executive Director of The Seabury Institute for Pastoral Psychotherapy, Atlanta, Georgia.

Verbal contingent stimulation of stuttering in laboratory and home settings

The effect of verbal contingent stimulation for stuttering behaviors was examined during changes of stimulus delivery mode and experimental setting. In Experiment I, contingent stimuli were delivered in the laboratory setting with the experimenter and subject in a face-to-face arrangement versus presentations by the experimenter from a control room via a headset arrangement. In Experiment II, contingent stimulation of stuttering was examined in the laboratory and home setting. Findings revealed that stuttering frequency was reduced in all conditions of both experiments. However, the only significant reductions occurred under the headset delivery conditions in the laboratory setting.     

Competence and processing in children's grammar of relative clauses

We report two toy-manipulation experiments investigating 4–5-year-old children's interpretations of relative clauses. In the first experiment we show that the frequency with which relatives modifying the matrix direct object are interpreted as referring to the matrix subject is sensitive to the nature of the material in the relative. Animacy of the relative direct object leads to an increase in subject coreference errors for relatives; a similar effect of animacy was not found for infinitival complements. We propose that such errors arise when the child's sentence processor is taxed. In our second experiment we compare children's interpretations of relatives to their interpretations of temporal participial complements. Children eschewed coreference between the complement and the object of a passive prepositional phrase in the case of temporal participials but not in the case of relatives. We interpret this result as evidence that children are capable of analyzing relatives as constituents of the NP node, and hence that this node is recursive in their grammars. We discuss the results of both experiments in the context of a two-stage parsing model, arguing that our data fit a picture of children's linguistic abilities in which the 4-year-old has a sophisticated competence grammar and a parsing mechanism of essentially the same structure as the adult's. We compare our approach to a number of other approaches to children's relative clause interpretations in the literature, arguing that these alternatives are too structure-specific and can lead to underestimations of the child's competence grammar. We conclude that our analysis is compatible with a picture of acquisition in which the child's competence grammar of relatives is not qualitatively different from the adult's.     

Event-related potential studies of cerebral specialization during reading: I. Studies of normal adults

A number of methodological features were incorporated in a paradigm designed to maximize the likelihood of finding reliable event-related potential (ERP) signs of functional specializations between and within the cerebral hemispheres. Every subject was more accurate in identifying words presented to the right than to the left visual field. The morphology of the ERPs elicited by these words varied considerably as a function of electrode position both within and between the hemispheres. Amplitude asymmetries of ERP components recorded from occipital regions of the two hemispheres varied systematically with the position of the word in the visual field. On the other hand, ERPs from more anterior (temporal and frontal) regions displayed large asymmetries which were in the same direction regardless of the visual field of word presentation. The most prominent such asymmetry was in the negativity in the region 300–500 msec (N410) which was larger in the left than the right hemisphere in every subject. These results demonstrate that in this paradigm which demands specialized language processing ERPs are sensitive to aspects of cerebral organization both within and between the two hemispheres.     

An ultrasonic auditory stimulator

An auditory stimulator with a frequency range to 40 kHz is described. The onset and cessation of the stimulation tone are carefully shaped in order to eliminate unwanted clicks. Rats have shown marked responses in electrical brain activity to ultrasonic stimulation.
