Role of the unquantified electroencephalography in psychiatric research

This paper outlines potential research applications of the unquantified (paper or digital) electroencephalography (EEG) in psychiatry. Three main areas are highlighted: first, the need for thorough familiarity with the unquantified EEG is emphasized, including the ability to confidently recognize all normal and abnormal activities that could influence further analysis of the record as well as artifacts that can contaminate the tracings; second, the fact that definitive studies relating EEG abnormalities to psychiatric symptomatology and clinical response are lacking; and third, the potential for EEG to be utilized as a tool to decrease the risk of invasive research studies is discussed.     

The deterioration of semantic memory in Alzheimer's disease.

Semantic memory impairment is a common feature of dementia of the Alzheimer type (DAT). Recent research has shown that patients with DAT are more impaired (relative to non-demented controls) in generating exemplars from a particular semantic category (e.g., animals) than words beginning with a particular letter, exhibit an altered temporal dynamic during the production of category exemplars, are impaired on confrontation naming tasks and make predominantly superordinate or semantically related errors, consistently misidentify the same objects across a variety of semantic tasks, and have alterations in multi-dimensional scaling models of their semantic network that are indicative of a loss of concepts and associations. These results are consistent with the view that Alzheimer's disease results in a breakdown in the organization and structure of semantic knowledge as neurodegeneration spreads to the association cortices that presumably store semantic representations.     

Reading speech and hearing print: constraining models of visual word recognition by exploring connections with speech perception.

Current models of reading and speech perception differ widely in their assumptions regarding the interaction of orthographic and phonological information during language perception. The present experiments examined this interaction through a two-alternative, forced-choice paradigm, and explored the nature of the connections between graphemic and phonemic processing subsystems. Experiments 1 and 2 demonstrated a facilitation-dominant influence (i.e., benefits exceed costs) of graphemic contexts on phoneme discrimination, which is interpreted as a sensitivity effect. Experiments 3 and 4 demonstrated a symmetrical influence (i.e., benefits equal costs) of phonemic contexts on grapheme discrimination, which can be interpreted as either a bias effect, or an equally facilitative/inhibitory sensitivity effect. General implications for the functional architecture of language processing models are discussed, as well as specific implications for models of visual word recognition and speech perception.     

Marital satisfaction and topographical assessment of marital interaction: A longitudinal analysis of newlywed couples

Despite numerous tests of social learning hypotheses relating to marriage, important questions remain concerning how best to quantify behavior displayed in marital interaction. In the present study, 60 newlywed couples reported their marital satisfaction, engaged in a 15-minute problem-solving discussion, and reported their marital satisfaction again 6 and 12 months later. The interactions were microanalytically coded, the codes were assigned a numeric value, and each spouse's cumulative point totals were plotted as a function of time in the interaction. This was done separately for all 60 couples. Graphs were divided into groups based on the topography of the graphically represented interactions. These groups differed cross-sectionally and longitudinally in their level of marital satisfaction. Couples tended to have lower satisfaction scores when their initial interactions were characterized with behavioral parity between the spouses at the beginning of a discussion, changing to asymmetrical patterns of behavior later in the conversation. This method was found to be more predictive of marital satisfaction than were standard methods of assessing dyadic interaction (i.e., base rates of behavior and sequential analysis). Implications of these data for understanding how interactions relate to the course of newlywed marriage are discussed.     

That’s the way the ball bounces: infants’ and adults’ perception of spatial and temporal contiguity in collisions involving bouncing balls

Three experiments investigated the perception of collisions involving bouncing balls by 7- and 10-month-old infants and adults. In previous research, 10-month-old infants perceived the causality of launching collisions (events in which one object moves along a smooth horizontal trajectory toward a second object, apparently launching it into motion) in relatively simple event contexts. In more complex event contexts, infants failed to discriminate among the events or respond to changes in individual features. Experiments 1 and 2 of the present investigation revealed that 7- and 10-month-old infants attended to spatial and temporal contiguity, but not causality, in collisions involving the movement of bouncing balls. In Experiment 3, both spatiotemporal contiguity and general knowledge about movement trajectories influenced adults’ judgments of causality for these collisions. The present results add to a growing understanding of infants’ event perception as constructive and a function, in part, of the complexity of the event context.     

New Approaches to Teaching Early Confucianism

Teachers are often tempted to present early Confucianism as an abstract ethical philosophy whose wisdom stands outside of time and space. Nevertheless, this kind of rarefied treatment makes it difficult for students to understand. Instead, one should try to make Confucianism more tangible by firmly placing it in its historical and intellectual context. This can be done in the following ways: Use indigenous nomenclature for words like “Confucius” and “Confucianism.” Closely examine the history and character of the Confucian community. Draw attention to the overwhelming importance of ritual in Confucian doctrine. Underline the all-encompassing nature of Confucian religiosity. Show the popular stories and images by which Confucians transmitted their teachings. Although these methods focus on the otherness of early Confucianism and thereby might make it less appealing to modern tastes, they will provide students with a lively and vivid image of the early tradition and its advocates.     

Familiarity and pronounceability of nouns and names

Ratings of familiarity and pronounceability were obtained from a random sample of 199 surnames (selected from over 80,000 entries in the Purdue University phone book) and 199 nouns (from the Ku?era-Francis, 1967, word database). The distributions of ratings for nouns versus names are substantially different: Nouns were rated as more familiar and easier to pronounce than surnames. Frequency and familiarity were more closely related in the proper name pool than the word pool, although both correlations were modest. Ratings of familiarity and pronounceability were highly related for both groups. A production experiment showed that rated pronounceability was highly related to the time taken to produce a name. These data confirm the common belief that there are differences in the statistical and distributional properties of words as compared to proper names. The value of using frequency and the ratings of familiarity and pronounceability for predicting variations in actual pronunciations of words and names are discussed.     

The effectiveness of psychoanalytic psychotherapy: the role of treatment duration, frequency of sessions, and the therapeutic relationship

This is an effectiveness study of treatment outcome that relies on patients' perception of their mental health during and after psychoanalytic psychotherapy. Ninety-nine outpatients attending the IPTAR Clinical Center (ICC) responded to the Effectiveness Questionnaire (EQ) adapted from that developed by Consumer Reports. Effectiveness is studied from various perspectives. Findings indicated (1) an incremental gain in effectiveness scores from six to over twenty-four months of therapy; (2) an incremental gain with greater session frequency from one to two or three weekly sessions; (3) facilitation of effectiveness by the experience of a positive relationship with the therapist; (4) an interplay between clinical syndrome and treatment conditions. A method giving clinical validity to the quantitative findings is described. Brief summaries of two recorded interviews reveal differential reconstruction of events that had occurred during treatment. The findings are discussed from the vantage point of two hypotheses: cognitive dissonance and internalization of therapeutic experience.     

Early sexual experiences among pregnant and parenting adolescents.

One hundred sixty-six pregnant or parenting adolescent females completed a survey regarding early sexual experiences (wanted and unwanted), family dysfunction and violence, and health-risky behaviors occurring prior to age 18. Fifty-three percent had at least one unwanted sexual experience. Younger age at first unwanted sexual experience was associated with younger age at first wanted sexual experience. Adolescent females with an unwanted sexual experience, as compared to those without, were more likely to be victims of physical violence, to have run away, to be substance abusers, and to have family members with drug or alcohol problems. Four factors explained 39% of the variance in age at first pregnancy: presence of a family member with a drinking problem, age first got hit with a belt or other object by a family member, age first got drunk, and age at first wanted sexual experience. It was concluded that the prevention of teenage pregnancy entails a multifaceted approach that addresses family life, early sexual experiences, and health-risky behaviors.     

Children's artistic responses to musical intervals

In one experiment, White South African boys drew pictures in response to four musical intervals. In the second, the subjects were of both sexes and drawn from White, urban Black, and rural Black populations. Six intervals were used. Drawing content was similar cross-culturally. Consonances were perceived as generally positive; dissonances, generally negative. There was also an activity dimension. Children in a lower grade drew more concrete pictures than did those in a higher grade, regardless of age. Even young listeners were fairly consistent in their responses. This suggests that perception of musical meaning is a universal rather than culturally based phenomenon.
