On Alan Turing's anticipation of connectionism

It is not widely realised that Turing was probably the first person to consider building computing machines out of simple, neuron-like elements connected together into networks in a largely random manner. Turing called his networks unorganised machines. By the application of what he described as appropriate interference, mimicking education an unorganised machine can be trained to perform any task that a Turing machine can carry out, provided the number of neurons is sufficient. Turing proposed simulating both the behaviour of the network and the training process by means of a computer program. We outline Turing's connectionist project of 1948.In Memory of Robin Gandy     

Is Speech Arrest during Wada Testing a Valid Method for Determining Hemispheric Representation of Language?

Background and objective: The intracarotid amobarbital procedure, or Wada test, is the method of choice to determine hemispheric representation of language, and is routinely used in the presurgical evaluation for intractable epilepsy. Some investigators perform comprehensive language assessments, but others base language lateralization solely on speech arrest. This study sought to determine whether speech arrest alone during Wada testing provides valid data regarding language lateralization. Methods: The subjects (previously reported) were 21 patients evaluated for intractable epilepsy, who underwent language lateralization by Wada testing and functional MRI (FMRI). For each patient, language representation was determined by calculating: (1) a Wada laterality index based exclusively on speech arrest; (2) a Wada laterality index based on comprehensive language assessment; and (3) an FMRI laterality quotient. Correlation coefficients and categorical classifications were analyzed. Results: There was no significant correlation between the Wada laterality quotient derived from duration of speech arrest and either the comprehensive Wada language laterality score (r= .35,p= .12) or FMRI language laterality score (r= .32,p= .16). Categorical classification as left, right or bilateral language also showed marked discordance between speech arrest and the other two methods. Conclusion: Duration of speech arrest during Wada testing is not a valid measure of language dominance.     

You'll Never Believe This: Irony and Hyperbole in Expressing Surprise

Three experiments compared how people comprehend irony and hyperbole as expressing surprise. Experiment 1 demonstrated that, when irony and hyperbole are used together, they express more surprise than if either is used alone. There was no difference between the degree of surprise expressed by hyperbole and irony, although both expressed more surprise than literal commentary. Experiment 2 revealed that, when a speaker has exaggerated about some unexpected event, as much surprise is expressed by very slight, realistically possible hyperbole as by outlandish, impossible hyperbole. In a third experiment the range of possible levels of hyperbole tested in Experiment 2 was shown to cause differences in how easy it was to determine that a speaker was surprised at some turn of events. The results are discussed in terms of theories of irony and hyperbole comprehension.     

Lifelong Mild Bad Feelings: A Review and Solution to a Psychotherapeutic Enigma

A review indicates that (a) comparatively little is known about the common phenomenon of lifelong mild bad feelings, and (b) psychotherapy has generally overlooked an effective focus on this enigmatic feeling state. As an invitation for clinicians to provide more attention to this feeling state, a proposal is suggested toward one way of freeing a patient of lifelong mild bad feelings in the course of a session.     

The Impact of Sex and Gender Role Self-Perception on Affective Reactions to Different Types of Film

To what extent do differences in biologicalsexand psychological gender identity influence affectivereactions to different genres of film? In order toaddress this question, this investigation examined the impact of sex and gender roleself-perceptions on viewers' responses to neutral,melodramatic, and violent film segments. Working with apredominantly Caucasian population (93% Caucasian) at asoutheastern university, the results emphasize theimportance of sex and gender role self-perceptions onviewers' affective responses to media entertainment. Theimplications of these findings are discussed.

     

Prevalence of ADHD and comorbid disorders among elementary school children screened for disruptive behavior

In the context of a school-based prevention of conduct disorder program, 7,231 first- through fourth-grade children were screened for cross-setting disruptive behavior. Frequencies of DSM-III-R psychiatric disorders and patterns of comorbidity were assessed. We also examined the association of psychiatric diagnosis with child and parent characteristics to determine differential risk based on diagnostic subgroups. Attention deficit hyperactivity disorder (ADHD) and oppositional-defiant disorder (ODD) were the most frequent diagnoses. Mood and anxiety disorders were infrequent as single diagnoses. Patterns of comorbidity demonstrated that both externalizing and internalizing disorders commonly cooccurred with ADHD. More severe degrees of psychopathology and psychosocial risk accrued to the subgroup of youths with ADHD plus a comorbid externalizing disorder.This study was supported by grant MN-46584 from the National Institute of Mental Health.     

EXPANDING THE MOTHER-CHILD PARADIGM

Reliance on the mother–child dyad as the primary context for under–standing child development has caused fathers to be underrepresented in published research on child development and developmental psychopathology. In order to investigate whether this pattern was also evident in the work of future psychologists, we reviewed Dissertation Abstracts from 1986 through 1994. Results showed that fathers were the focus of significantly fewer dissertation studies (10.5%) than were mothers (59.5%) or both parents (30.0%). We argue that essentializing the mother–child bond is a political philosophy about the roles of men and women that places the discipline of psychology at risk for inadvertently becoming an apologist for the neoconservative political right. Specific suggestions for revising graduate training are presented. The social policy implications for continuing this trend into the next generation of psychologists are discussed.     

Gender and aggression II: Personal aggressiveness

To investigate how gender, ethnicity, age and education influence aggressiveness, we surveyed 115 male and female college students (56% male; 50% Anglo and 26% Hispanic) and 79 persons (72% male; 92% Anglo) working on a military base. Participants were administered the Buss-Perry Aggression Questionnaire and asked about their own aggressive behaviors. In both samples, men scored significantly higher than women on the Physical Aggression scale of the Aggression Questionnaire but not on the other scales. In the military sample, men indicated that they expected to behave more aggressively than women. Positive correlations among different aspects of aggressiveness were found for both men and women. Increasing age and education were associated with lower aggressiveness in both genders, suggesting that aggressiveness may be susceptible to modification over the course of one's life.We would like to thank Angela Bennett, Gail Bliss, Kayleigh Carabajal, Julie Depree, Carmen Gonzales, Deborah Good, Scott Griffin, Gladys Herrera, George Selix, Ruth Tangman, and Jon Woodland for their assistance with the development, distribution, and coding of the questionnaire.     

Group climate in an open-ended cancer support group

A number of well-described, controlled studies assessing cancer support group intervention support their effectiveness. All of these experimental groups have been close-ended and typically involve six to eight weekly sessions. Because many cancer patients are unable or unwilling to participate in closed, extended-session groups, there is particular need for analysis of the effectiveness of short-term, open-ended groups. Additionally, objective measures are needed to delineate the factors contributing to a successful outcome in cancer support groups. We used the Short Form of the Group Climate Questionnaire (GCQ-S) to characterize 23 sessions in an open-ended, short-term, Veterans Hospital based cancer support group. The cancer group scored significantly lower on the Avoiding and Conflict dimensions (p<.001) compared to a normative psychotherapy group sample. There was no difference on the Engaged dimension. This pilot study suggests that a cancer support group in this setting can create an environment where members are cohesive and take responsibility for their own change process, while keeping interpersonal conflict to a minimum. Based on these preliminary findings, we encourage controlled clinical trials examining the efficacy of open-ended cancer support groups.At the time of this study, Dr. Daroff was a resident in Psychiatry, University of California, San Francisco.
