Separating global and specific factors in developmental dyslexia

The general goal of the study was to identify global and specific components in developmental dyslexia using various manipulations based on the rapid automatization paradigm (RAN). In two experiments, we used both factor analysis and the Rate-and-Amount Model to verify if one (or more) global factor(s) and a variety of specific effects contribute to the naming (and visual search) deficits in children with dyslexia. Results of Experiment 1 indicated the presence of three global components: pictorial naming, detailed orthographic analysis, and visual search. Pictorial naming is predicated by typical RAN tasks (such as naming colors or objects), independent of set size, but also from a variety of other tasks including Stroop interference conditions. The detailed orthographic analysis factor accounts for naming of orthographic stimuli at high set size. Visual search marked tasks requiring the scanning of visual targets. Results of Experiment 2 confirmed the separation between the pictorial naming and detailed orthographic analysis factors both in the original sample and in a new group of children. Furthermore, specific effects of frequency, lexicality, and length were shown to contribute to the reading deficit. Overall, it is proposed that focusing on the profile of both global and specific effects provides a more effective and, at the same time, simpler account of the dyslexics' impairment.     

Psychosocial predictors of relapse in cocaine-dependent patients in treatment

Relapses in cocaine abusers in treatment are an important problem. The majority of patients are incapable of sustaining abstinence over any length of time. To identify the factors associated to relapses risk in the cocaine use can be an optimal choice to improve the treatment strategies. The aim of this study was to analyze relapse-risk factors in cocaine-dependent patients on treatment. Participants were 102 patients who had begun outpatient treatment at a public health center in Spain. Some functional areas and cocaine use are evaluated for a period of six months. A structural equations model was used to identify possible predictive variables. The results show that social-family environment and economic-employment situation were associated with greater risk of relapse. Likewise, the social-family environment was related to severity of addiction. It is concluded that the incorporation of family intervention strategies and vocational/employment counseling may help to reduce relapse rates in cocaine addicts receiving treatment.     

Web-based, psychosocial treatment for substance use disorders in community treatment settings

The purpose of this multisite clinical trial was to evaluate the effectiveness of a web-based version of the Community Reinforcement Approach, plus motivational incentives, within community-based, outpatient substance abuse treatment. This ongoing study is being conducted within the National Drug Abuse Treatment Clinical Trials Network, funded by the National Institute on Drug Abuse. Midway through the enrollment of 500 participants, the study is being implemented in 10 treatment programs across the United States. Information is provided on design, sample, intervention and technology, and preliminary lessons learned.     

Gender stereotyping in young children: Evidence to support a concept-learning approach

Two studies on early gender stereotyping based on a concept-learning approach were conducted. With the use of a forced choice format, study 1 found that both 2 1/2 and 3 1/2-year-old children showed significant and equal stereotyping of both gender-labeled infants and animals. These findings suggest both early learning and generalization of gender stereotypes. In study 2, although 5-year-olds stereotyped more strongly than 3-year-olds, both groups stereotyped others significantly more than themselves. When attributing traits to themselves, children chose the more socially desirable rather than the gender-traditional attributes. These findings are discussed in terms of the acquisition of gender stereotypes as a process distinct from the necessity for related self-schemas.The authors would like to express their appreciation to Pam Newman, Laurie MacGavin, Rebeccah Warren, Sheryl Wilson, Gail McCollum, and Cheryl Hessen for their invaluable assistance in running subjects for these studies.     

Hispanic and majority student attitudes toward forcible date rape as a function of differences in attitudes toward women

Less rejecting attitudes toward forcible date rape are related to more traditional attitudes toward women, as measured by the Attitudes Toward Women Scale (G. J. Fischer, “College Student Attitudes Toward Forcible Date Rape. I. Cognitive Predictors,” Archives of Sexual Behavior, 1986, 15, 457–466). Does this relation reflect more traditional or more negative attitudes toward women? If the former, then an ethnic minority having still more traditional attitudes toward women (than the nonethnic majority), also should be less rejecting of forcible date rape. This hypothesis was assessed by surveying attitudes of bicultural and bilingual Hispanic, other self-reported Hispanics, and nonethnic majority college students from a large introductory sociology class in a large Southwestern university. Results showed that Hispanics, overall, (1) had more traditional attitudes toward women than nonethnic majority and (2) as hypothesized, had less rejecting attitudes toward forcible date rape. However, these effects were not a simple function of ethnicity, at least not for males. For example, bicultural and bilingual Hispanic males were least likely to blame the male for the forcible date rape, but were no less rejecting of such behavior than other Hispanic males and had no more traditional attitudes toward women than other Hispanic or majority males. Bicultural and bilingual Hispanic females, on the other hand, were most likely to blame the male, had the least rejecting attitudes toward date rape, and had the most traditional attitudes toward women. one interpretation is that exposure to less restrictive sex roles of the majority culture is a liberating influence on Hispanic females, but not on Hispanic males who, perhaps, see more liberal attitudes toward women as having no or even negative payoff. Differences found between Hispanics who are bicultural and bilingual and other self-reported Hispanics suggest that these groups should not be combined, and that a research sample needs to be defined more specifically than “Hispanic.”     

Development of kinetic images: When does the child first represent movement in mental images?

An experiment investigated at what age children could represent movement in imagery. Five- and eight-year olds were asked whether two stimuli were the same or different in shape. The two stimuli were either presented in the same orientation or one stimulus differed from the other by clockwise rotation of 30 ° (0.52 rad), 60 ° (1.05 rad), 120 ° (2.09 rad), or 150 ° (2.62 rad). Children were instructed to visually imagine the counterclockwise rotation of one shape into the position of the other to help make the judgment. For both 5- and 8-yr olds, reaction times increased as a linear function of angular discrepancy between stimuli, indicating that both age groups represented rotation in their imagery. The findings conflict with Piaget and Inhelder's thesis that imagery representing movement first emerges when children are 7 to 8 yrs of age.     

Affective state and preference for immediate versus delayed reward

Fifty-two 9-year-olds were randomly assigned to success and failure treatment conditions involving acceptance or rejection of a drawing made for an art show. In a pilot study, this treatment was shown to influence significantly subjects' affective states. Just after treatment, subjects were presented with choices between pairs of small immediate and large delayed rewards. As predicted, subjects who had experienced success chose more often the large delayed reward than those who failed (p < .02). Prior expectancy for success and sex were not significantly related to choice behavior. The influence of affective state on various parameters of the choice paradigm was discussed, and other evidence was cited indicating that affective state is a major determinant of self-gratification behavior.     

A small-animal inhalation chamber for short-to-intermediate term exposure

An inhalation chamber for behavioral toxicology studies is described. Complete and uniform diffusion of test atmospheres throughout the chamber is achieved, thus solving a dead-airspace problem prevalent in extant chamber designs. Modular attachments to the chamber allow for a variety of uses, including physiological-pathological and classical or operant conditioning. The chamber design and size are appropriate for testing most small laboratory animals (e.g., birds, rodents, and small primates), but the chamber is easily modified for use with larger vertebrates. Despite the versatility of design, the chamber is relatively inexpensive and easy to build.     

Prejudice and discrimination within the school psychology profession: Survey results from the committee on prejudice and discrimination,Division of School Psychology,American Psychological Association

The committee on prejudice and discrimination, Division of School Psychology, American Psychological Association, conducted a survey in order to determine whether school psychologists have (a) experienced any prejudice and/or discrimination with respect to ethnicity, gender, age, and sexual orientation in salary schedule (in primary employment and in consultative employment), in tenure status, and in publication and grant productivity rate (number of articles published in professional journals, whether they have reviewed articles for journals, amount of typical research grant received); and (b) engaged in legal and/or legislative activity around any existing prejudice or discrimination. A total of 850 surveys were sent to a random sample of approximately 2,500 members of Division 16, American Psychological Association, and the total return was 52%, with 41.2% usuable responses. The results do not in themselves indicate bias with respect to ethnicity, gender, age, or sexual orientation. The findings do, however, indicate the need for further study regarding possible prejudice and discrimination.
