Parameterization of connectionist models.

We present a method for estimating parameters of connectionist models that allows the model's output to fit as closely as possible to empirical data. The method minimizes a cost function that measures the difference between statistics computed from the model's output and statistics computed from the subjects' performance. An optimization algorithm finds the values of the parameters that minimize the value of this cost function. The cost function also indicates whether the model's statistics are significantly different from the data's. In some cases, the method can find the optimal parameters automatically. In others, the method may facilitate the manual search for optimal parameters. The method has been implemented in Matlab, is fully documented, and is available for free download from the Psychonomic Society Web archive at www.psychonomic.org/archive/.     

Attitudes of Potential Providers Towards Preconceptional Cystic Fibrosis Carrier Screening

To determine the attitudes of potential providers (general practitioners and Community Health Service workers) towards preconceptual cystic fibrosis (CF) carrier screening and to determine which factors are associated with a positive attitude. A survey was conducted among 200 general practitioners (GPs) and 134 Community Health Service (CHS) workers. Fifty-two percent of the eligible GPs participated and 84% of the CHS workers. Fifty-five percent of the GPs and 73% of the CHS workers had a positive attitude towards routinely offering CF carrier screening, and more than 80% were in favor of informing the target population about the possibility of having a CF carrier test. A positive attitude was associated with (a) high perceived severity of CF, (b) religion (nonreligious compared to Reformed), (c) low perceived barriers, and (d) high perceived test reliability. The care providers who are most likely to be involved in a preconceptual CF carrier screening program, i.e. GPs and CHS workers, generally have a positive attitude towards the implementation of such a program.     

Components and Symbols of Ethnic Identity: A Case Study in Informal Education and Identity Formation in Diaspora

L’identité des membres de groupes ethniques qui vivent dans de nombreux pays est influencée par la culture environnante. Ce travail développe un outil qui peit aider les chercheurs à comprendre la façon dont les individus vivent leur identité ethnique. On analyse les composantes et les symboles qui fixent l’dentification ethnique. L’application de techniques d’analyse multidimentionnelle à un ensemble de données empiriques révéla une structure identitaire sur deux axes (cognitif–affectif; particulier–universel). Cette structure permet de faire des comparaisons entre des sous‐populations nationales selon leurs perceptions et accentuations diversifiées de l’identité ethnique. On examine ici les cas de membres de l’enseignement relevant de l’éducation juive informelle. 2119 de ces personnes provenant de sept pays ont fourni des définitions d’elles‐mêmes et des symboles qui exprimaient leur lien avec l’héritage ethnique et religieux. Cette typologie de base pourrait être utilisée dans des études portant sur d’autres groupes ethniques dont les membres ont émigré dans divers pays d’acceuil. The ethnic identity of members of ethnic groups who live in a number of different countries is influenced by the surrounding cultures. This study develops a tool which can help researchers understand the ways in which individuals perceive their own ethnic identity. The components and symbols that determine ethnic identification are analysed. By applying multidimensional analysis techniques to a set of empirical data, we were able to uncover a structure of identity along two axes: the cognitive/affective and the specific/universal. This structure enables us to make comparisons between national sub‐populations in terms of their various emphases and perceptions of ethnic identity. We examine here the case of staff members in Jewish informal educational settings: 2,119 staff members from seven countries were surveyed on the self‐definitions and symbols that express their relationship with their ethnic and religious heritage. This basic typology could be used in studies of other ethnic groups whose members have emigrated to a number of host countries.     

The effect of perceptual distinctiveness on the prospective and retrospective components of prospective memory in young and old adults.

In two experiments, the effect of perceptual distinctiveness of cues on prospective memory performance was examined. Young and older adults completed a visual search task with embedded prospective memory instructions. On each trial, participants were asked to indicate the position of a target letter in a letter string, unless either of two letters previously identified as prospective memory cues was presented. Each prospective cue was associated with a specific response. Perceptual distinctiveness was manipulated by spatially displacing a single letter. The prospective component (successful detection of the cue) and the retrospective memory component (recalling the correct response when a cue is detected) were measured separately. Perceptual displacement of cues modulated performance of the prospective component but not the retrospective component. Young adults successfully detected a larger proportion of cues (prospective component) than older adults. However, there were minimal effects of age and no effect of cue displacement on participants' ability to recall the intention once they detected a cue (retrospective component performance). Results are discussed within the context of current theoretical models of prospective memory.     

Art as the Silence of the World. An Attempt at a Phenomenological Interpretation

This paper provides an analysis of the paradoxical definition of art as the silence of the world, as presented in Maurice Blanchot’s The Space of Literature. The definition is analysed phenomenologically, by treating the world as the universal horizon of all experiences. The paper presents two possible interpretations of Blanchot’s statement. First, a possibility is considered that, according to Blanchot, in genuine artistic experience the mundane everyday life falls silent, and an autonomous fictional world opens up. The paper argues that while Blanchot does oppose art to everyday life, this interpretation is insufficient. Firstly, because on the basis of the phenomenological premise, all possible worlds fall within the universal world-horizon, and secondly, the function Blanchot attributes to art is considerably more radical, as when he speaks about the directedness of art outside of all possible worlds. While such an aim may seem impossible from the viewpoint of the phenomenological premise, the second part of the paper demonstrates that it can indeed be meaningfully interpreted on the basis of Martin Heidegger’s transcendent approach to the world. According to this interpretation, while the phenomenological premise prevents all discussion of places and experiences outside the world, a liminal experience can nevertheless be discussed. If this is true, it is not an entity within the world which opens up, but rather the world-horizon itself in the form of an anxious silence.     

Distinguishing the desire to learn from the desire to perform: The social value of achievement goals

We sought to distinguish mastery goals (i.e., desire to learn) from performance goals (i.e., desire to achieve more positive evaluations than others) in the light of social judgment research. In a pilot study, we made a conceptual distinction between three types of traits (agency, competence, and effort) that are often undifferentiated. We then tested the relevance of this distinction for understanding how people pursuing either mastery or performance goals are judged. On self-perception, results revealed that effort was predicted by the adoption of mastery goals and agency by performance goals (Study 1). On judgments, results showed that (a) the target pursuing mastery goals was perceived as oriented toward effort, and (b) the target pursuing performance goals was oriented toward agency (Study 2). Finally, these links were shown again by participants who inferred a target’s goals from his traits (Study 3). Results are discussed in terms of the social value of achievement goals at school.     

Construct Validity of the Acquired Capability for Suicide Scale: Factor Structure,Convergent and Discriminant Validity

The Acquired Capability for Suicide Scale (ACSS) assesses one of three main constructs in the Interpersonal Theory of Suicide but evidence of its validity is limited. In two studies (Ns = 287 and 738) validity of the full 20-item ACSS and its shorter versions (ACSS-5, ACSS-8, ACSS-FAD) were examined in terms of factor structure and relation to indices of self-reported suicidal behaviour and self-harm. Confirmatory factor analysis (CFA) failed to show good fit for one-, two-, or three-factor models of the ACSS in its various versions. Exploratory factor analysis of the 20-item scale in the first study pointed instead to a five-factor structure and this was supported using CFA in the second study. In both studies all scale versions showed moderate negative correlations to fear of death and dying, indicating scale validity for the purpose of assessing fearlessness about death. In the second study, a model in which the five factors were indicators of a latent variable of Capability was found to predict a latent variable of Suicidality as indicated by suicidal behaviours, but the prediction was substantially enhanced by the addition of Item 20 to the model. This single item was also found in the first study to better predict suicidal and self-harming behaviour than the full ACSS or any of its short versions.     

Considering Gestational Life

This paper is an exploration into the question, “What does considering gestational life add to analytic theory and practice?” It attempts to situate prenatal experience in the psychoanalytic dialogue, to explore its place in subsequent mental life, to discuss how this may be useful in clinical process, and to reconceptualize some theory in light of a gestational perspective. Neuro-psychoanalytic theory is utilized with an emphasis on nonconscious mental process which takes the form of implicit memory, providing people with a sense of continuity and well-being or stress. Intra-uterine experience can include pain and suffering. Fetal stress is an integral part of prenatal development and its metaphorical use in clinical practice. Three concepts—gestational being/becoming, geatational holding, and objectless intersubjectivity—are offered as ideas to introduce order and conceptual clarity into the ineffable mysteries of in utero process. A gestational perspective is used to describe how the analyst intuitively tracks the patient’s sense of well-being/stress.     

Genetic Counselor Workforce Issues: a Survey of Genetic Counselors Licensed in the State of Indiana

The aims of this study were to document movement of genetic counselors (GCs) out of clinical positions and identify factors that might help employers attract and retain clinical GCs. A confidential on-line survey of GCs ever licensed in the state of Indiana was conducted. Of the 46 respondents, most provide direct patient care (69.6 %), have worked in their current position for 5 years or less (72.1 %), and are experienced genetic counselors, having graduated between 6 and 15 years ago (43.5 %). One-third (32.6 %) reported thinking about leaving their current position at least monthly. GCs were more likely to think about leaving their current position when they provided direct patient care (p = 0.04) and worked in a hospital/clinic setting (p = 0.01). Among the 18 respondents that changed jobs in the past two years, 55.6 % currently work in a laboratory/industry setting and 44.4 % provide direct patient care, compared to 8 % of those in a stable position (N = 25) who work in a laboratory/industry setting (p < 0.01) and 88 % who provide direct patient care (p < 0.01). Genetic counselors who have changed jobs within the past 2 years were more satisfied with the possibility for advancement (p = 0.01), the recognition for work they do (p = 0.03) and feeling value from the organization (p = 0.04) in their current positions than those who have not changed jobs. Salary and flexibility were most often reported as reasons for changing jobs. This is the first documentation of the movement of GCs out of clinical roles into industry positions. This changing landscape may impact the access to clinical services and the training of genetic counseling students. This data will provide employers with data to help attract and retain GCs in clinical roles.
