Psychodynamic Theory and Counseling in Predictive Testing for Huntington’s Disease

This paper revisits psychodynamic theory, which can be applied in predictive testing counseling for Huntington’s Disease (HD). Psychodynamic theory has developed from the work of Freud and places importance on early parent–child experiences. The nature of these relationships, or attachments are reflected in adult expectations and relationships. Two significant concepts, identification and fear of abandonment, have been developed and expounded by the psychodynamic theorist, Melanie Klein. The processes of identification and fear of abandonment can become evident in predictive testing counseling and are colored by the client’s experience of growing up with a parent affected by Huntington’s Disease. In reflecting on family-of-origin experiences, clients can also express implied expectations of the future, and future relationships. Case examples are given to illustrate the dynamic processes of identification and fear of abandonment which may present in the clinical setting. Counselor recognition of these processes can illuminate and inform counseling practice.     

Learning multiple rules simultaneously: Affixes are more salient than reduplications

Language learners encounter numerous opportunities to learn regularities, but need to decide which of these regularities to learn, because some are not productive in their native language. Here, we present an account of rule learning based on perceptual and memory primitives (Endress, Dehaene-Lambertz, & Mehler, Cognition, 105(3), 577–614, 2007; Endress, Nespor, & Mehler, Trends in Cognitive Sciences, 13(8), 348–353, 2009), suggesting that learners preferentially learn regularities that are more salient to them, and that the pattern of salience reflects the frequency of language features across languages. We contrast this view with previous artificial grammar learning research, which suggests that infants “choose” the regularities they learn based on rational, Bayesian criteria (Frank & Tenenbaum, Cognition, 120(3), 360–371, 2013; Gerken, Cognition, 98(3)B67–B74, 2006, Cognition, 115(2), 362–366, 2010). In our experiments, adult participants listened to syllable strings starting with a syllable reduplication and always ending with the same “affix” syllable, or to syllable strings starting with this “affix” syllable and ending with the “reduplication”. Both affixation and reduplication are frequently used for morphological marking across languages. We find three crucial results. First, participants learned both regularities simultaneously. Second, affixation regularities seemed easier to learn than reduplication regularities. Third, regularities in sequence offsets were easier to learn than regularities at sequence onsets. We show that these results are inconsistent with previous Bayesian rule learning models, but mesh well with the perceptual or memory primitives view. Further, we show that the pattern of salience revealed in our experiments reflects the distribution of regularities across languages. Ease of acquisition might thus be one determinant of the frequency of regularities across languages.     

Psychoanalysis is a two‐way street

The paper discusses psychoanalysis as a mutual exchange between the analyst and analysand. A number of questions are raised: What was Ferenczi's and the early psychoanalysts' contribution to the interpersonal relational dynamics of psychoanalytic treatment? Why did countertransference become an indispensable tool in relationship‐based psychoanalysis? Why is the transference‐countertransference dynamic seen as a special dialogue between the analyst and analysand? What was Ferenczi's paradigm shift in the trauma theory? How did he combine the object relation approach with Freud's original trauma theory? The paper illustrates through some case study vignettes the intersubjective and intrapsychic dynamic in the process of traumatization. We can look at countertransference as an indicator of the patient's basic interpersonal experiences and traumas. Finally the paper discusses countertransference in the light of attachment theory, connecting the early initiatives of inter‐relational approaches in psychoanalysis with recent research.     

The crucial role of tense for verb production

The case of an aphasic patient whose spontaneous speech contains very few lexical verbs is reported. Instead of sentences with lexical verbs, the patient produces many (grammatical) copular constructions. He also substitutes lexical verbs with the copula. Although this results in ungrammatical utterances, by doing so, a resemblance of sentence structure and a degree of grammaticality of his utterances are preserved. Although the patient is more impaired in naming action than object pictures, it is unlikely that lexical retrieval difficulties are solely responsible for the paucity of lexical verbs in his speech. A series of tests revealed a profound deficit in producing tense marking inflections and in understanding their significance. We argue that the unavailability of tense features is the primary reason for the lack of lexical verbs in his speech. An alternative possibility, that the tense deficit interacts with the verb retrieval deficit, is also discussed. The patient has a complex lesion and language profile, with features associated with both Broca's and Wernicke's aphasia. However, since the study focuses on his verb and tense deficits and the grammaticality of his utterances, issues that are often discussed in relation to agrammatic Broca's aphasia, the literature that is relevant to these topics and to Broca's aphasia is reviewed, despite the different diagnostic profile of the patient.     

Sleep-dependent consolidation of procedural motor memories in children and adults: the pre-sleep level of performance matters

In striking contrast to adults, in children sleep following training a motor task did not induce the expected (offline) gain in motor skill performance in previous studies. Children normally perform at distinctly lower levels than adults. Moreover, evidence in adults suggests that sleep dependent offline gains in skill essentially depend on the pre-sleep level of performance. Against this background, we asked whether improving children's performance on a motor sequence learning task by extended training to levels approaching those of adults would enable sleep-associated gains in motor skill in this age group also. Children (4-6 years) and adults (18-35 years) performed on the motor sequence learning task (button-box task) before and after ~2-hour retention intervals including either sleep (midday nap) or wakefulness. Whereas one group of children and adults, respectively, received the standard amount of 10 blocks of training before retention intervals of sleep or wakefulness, a further group of children received an extended training on 30 blocks (distributed across 3 days). A further group of adults received a restricted training on only two blocks before the retention intervals. Children after standard training reached lowest performance levels, whereas in adults performance after standard training was highest. Children with extended training and adults after reduced training reached intermediate performance levels. Only at these intermediate performance levels did sleep induce significant gains in motor sequence skill, whereas performance did not benefit from sleep in the low-performing children or in the high-performing adults. Spindle counts in the post-training nap were correlated with performance gains at retrieval only in the adults benefitting from sleep. We conclude that, across age groups, sleep induces the most robust gain in motor skill at an intermediate pre-sleep performance level. In low-performing children sleep-dependent improvements in skill may be revealed only after enhancing the pre-sleep performance level by extended training.     

Community psychology values and the culture of graduate training: A self-study

In this self-study of an M.A. program in community psychology, the authors focused on evaluation of training goals related to the values of collaboration, empowerment, and diversity. Employing quantitative and qualitative methods, the evaluator, a thesis student in the program, cooperated with a stakeholder committee and other student, staff, and faculty members of the program to construct the methods and interpret the findings. Although the converging sources of data showed that the program was meeting its process goals to some extent, several key issues in the culture of training, such as the status of women, the psychological sense of community, and a supportive learning environment, needed improvement. The authors interpret the findings in terms of the impact of the university system and patriarchal norms on training in community psychology. This study is based on the first author's M.A. thesis, which the second author supervised. Judit Alcalde works in health promotion with the Regional Municipality of Waterloo, Community Health Department. She presented an earlier version of this work at the conference of the Canadian Psychological Association, Calgary, Alberta, June 1991. We are grateful to the thesis committee members for their support and guidance, to our colleagues for their participation, to Paul Davock, and to the reviewers and editor for their helpful comments.
