Ego Constriction

The terms ego constriction, ego inhibition, and ego restriction have not been clearly differentiated in their usage in the literature. In this paper a rationale for "ego constriction" as an entity distinct from both ego inhibition and ego restriction is given, despite its clear similarities to each. In a person with an ego inhibition, the ego inhibits a part of its own functioning because a particular function is linked to an unacceptable impulse. It is an internalized conflict. The person with an ego restriction, in contrast, avoids psychological pain triggered from an area in the outside world by restricting activity in that area. Like each of these problems but different, a person with an ego constriction first externalizes an internalized conflict associated with important functions or activities. Then, only through a series of particular obligatory steps can the person "overcome" the ego constriction--albeit temporarily. It is noted in this paper that the function of the specified obligatory steps is structurally parallel to the rigid obligatory behavior necessary for genital gratification in the perversions. As the recognition of this distinction arose in the course of an analysis of a mental health professional, something of the necessarily shared nature of analytic work is noticeable, shining through as the background for the work of this paper.     

Phonological underspecification and mapping mechanisms in the speech recognition lexicon

The problem of recognizing phonological variations in the speech input has triggered numerous treatments in speech processing models. Two areas of current controversy are the possibility of phonological underspecification in the mental lexicon and the nature of the mapping mechanism from the speech signal to the abstract lexical entry. We present data from cross-modal repetition priming experiments in English designed to test the differing predictions of speech recognition models regarding tolerance of phonological mismatch in speech. The results show effects of underspecification, supporting models using underspecified lexical entries (e.g. Lahiri & Marslen-Wilson, 1991; Reetz & Lahiri, 2001) over those using fully specified lexical entries (e.g., McClelland & Elman, 1986). The results also show no effects of context, thus favoring context-independent mapping, such as that in the three-way matching mechanism of the Lahiri and Reetz FUL model ( Lahiri, 1999; Reetz, 1998 and Reetz, 1999; Reetz & Lahiri, 2001) over context-dependent mapping used in phonological inference rules ( Gaskell and Marslen-Wilson, 1996 and Gaskell and Marslen-Wilson, 1998).     

Using video modeling and reinforcement to teach perspective-taking skills to children with autism

We evaluated video modeling and reinforcement for teaching perspective-taking skills to 3 children with autism using a multiple baseline design. Video modeling and reinforcement were effective; however, only 2 children were able to pass an untrained task, indicating limited generalization. The findings suggest that video modeling may be an effective technology for teaching perspective taking if researchers can continue to develop strategies for enhancing the generalization of these new skills.     

Adolescent Substance Use: Preliminary Examinations of School and Neighborhood Context

In considering the influences of microsystems on adolescent substance use, familial and peer contexts have received the most extensive attention in the research literature. School and neighborhood settings, however, are other developmental contexts that may exert specific influences on adolescent substance use. In many instances, school settings are organized to provide educational services to students who share similar educational abilities and behavioral repertoires. The resulting segregation of students into these settings may result in different school norms for substance use. Similarly, neighborhood resources, including models for substance use and drug sales involvement, may play an important role in adolescent substance use. We briefly review literature examining contextual influences on adolescent substance use, and present results from two preliminary studies examining the contribution of school and neighborhood context to adolescent substance use. In the first investigation, we examine the impact of familial, peer, and school contexts on adolescent substance use. Respondents were 283 students (ages 13 to 18) from regular and special education classrooms in six schools. Although peer and parental contexts were important predictors of substance use, school norms for drug use accounted for variance in adolescent use beyond that explained by peer and parental norms. Data from a second study of 114 adolescents (mean age = 15) examines neighborhood contributions to adolescent substance use. In this sample, neighborhood indices did not contribute to our understanding of adolescent substance use. Implications for prevention are presented.     

Gravity biases in a non-human primate?

Pre-school children expect falling objects to travel in a straight line even when there are clear physical mechanisms that deviate the object's path (Hood, 1995). The current study set out to determine whether this expectancy is limited to humans. Cotton-top tamarins (Saguinus oedipus oedipus), a New World monkey species, were tested on Hood's (1995) experimental task where objects are dropped down a chimney connected by an opaque tube to one of three containers. Like human children, there was a significant tendency to search in the container underneath the chimney where the food was dropped on the first trial, even though aligned chimneys and containers were never connected. These search errors suggest that there may be a gravity bias that operates when both primate species fail to understand the constraints operating on object trajectories. Unlike human children however, tamarins were generally more likely to perseverate in making errors even though repeated testing and cost incentives were used.     

Do infants possess innate knowledge structures? The con side

The central question of development is how new forms are made, how some structure, or behavior, or competence that was not there before, arises. This essay argues for a mechanistic answer to the question of the origins of new forms. And, in so doing, the essay argues that the so-called ‘innate versus learned’ dichotomy is logically flawed since ‘innate’ has no specifiable and mechanistic meaning. The essay considers first, a clear case of ‘innate’ structure: the origins of fingers and toes in embryology. The real-time mechanisms which create fingers and toes, however, are general, probabilistic, emergent and distributed across several levels of analyses. The idea of ‘innate’– even though certainly applicable – has no substantive content and yields no predictions about the nature of these mechanisms. The essay considers second, a clear case of a ‘learned’ structure: the origins of the shape bias in children’s early noun learning. Again, the developmental mechanisms are general, probabilistic, emergent and distributed across several levels of analyses. Several criticisms of the argument against ‘innate ideas’ are considered and rebutted.     

A computerized slot machine simulation to investigate the variables involved in gambling behavior

The present paper describes a computerized slot machine simulation designed to examine many of the potential variables involved in gambling behavior. This program was created in Visual Basic Version 6.0 and is designed to run on any Windows 95 or higher equipped computer. The program allows for experimenter manipulation of probabilities of payoffs, visual display of potential winning symbols, exact sequences of wins and losses, as well as pose run time questions to the subject on prespecified trials. The program records data on a trial-bytrial basis to a text file for easy importation into many data analysis and statistical programs. Conceptual and experimental questions that may be addressed with the described program are also discussed.     

Combining Trait Models of Impulsivity to Improve Explanation of Substance Use Behaviour

The UPPS‐P model of impulsivity is gaining popularity among personality and substance use researchers, but questions remain as to whether its five facets have incremental validity in explaining substance use over a more parsimonious model specifying only two facets: reward drive and rash impulsiveness. In three cross‐sectional studies (total N = 486), we investigated whether the novel components of the UPPS‐P model (negative Urgency, Premeditation, Perseverance, Sensation seeking, Positive urgency) predicted typical and problematic alcohol and cannabis use after accounting for reward drive, rash impulsiveness and trait neuroticism (assessed with the Eysenck Personality Questionnaire). Reward drive and rash impulsiveness scores were calculated using principal components analysis of multiple scales, including UPPS‐P premeditation and sensation seeking. Results showed that rash impulsiveness was a robust predictor of typical and problematic substance use. The novel facets of the UPPS‐P did not improve prediction of typical substance use. The urgency scales inconsistently predicted problematic use. Specifically, negative urgency predicted one of three measures of negative consequences from alcohol use, and positive urgency only predicted negative consequences from cannabis use. Results suggest that the three novel facets of the UPPS‐P model add little over a two component model in explaining substance use, although may provide preliminary evidence for the utility of a revised global urgency construct in explaining problematic substance use.
