Effects of exposure duration and eccentricity of global and local information on processing dominance

Abstract

The effects of exposure duration of stimuli and the eccentricity of local and global information in hierarchical patterns on processing dominance were examined using a paradigm of selective attention and masked stimuli. In the first experiment, the aim was to determine whether the exposure duration of stimuli has differential effects on processing dominance. Stimuli were presented with spatial certainty and controlled eccentricity at four exposure durations (unlimited, 140 msec, 70 msec and 40 msec). The results showed global advantage independently of the exposure duration used. Differential effects were obtained in relation to the interference between the global and local levels depending on the exposure duration. The purpose of the second and third experiments was to determine whether the eccentricity of local and global levels affects processing dominance under a condition of brief exposure duration of stimuli. The results of Experiment 2 showed local dominance when the eccentricity was different for both levels and biased to the local level (H's and S's stimuli). On the contrary, they showed global dominance when the eccentricity of the two levels was the same (C's stimuli). The results of Experiment 3 revealed that the effect of global dominance persisted when the stimuli presented local and global information foveally.     

Using Narrative Approaches to Teach Multicultural Counseling

Narrative approaches to teaching multicultural counseling can assist students in integrating course content with a sense of self. Narrative teaching strategies follow a postmodern view of learning—that is, that truth is constructed through the interaction of participants. Justification for narrative approaches to teaching multicultural counseling and narrative are introduced. Los enfoques narrativos para enseñar la consejería multicultural pueden ayudar a los estudiantes a integrar el contenido del curso con su sentido de ser. Las estrategias de la enseñanza narrativa siguen un panorama postmoderno de aprendizaje—que considera que la verdad se construye por la interacción de participantes. La justificación para enfoques narrativos para enseñar la consejería multicultural y la narrativa se introducen.     

Childbearing depressive symptomatology in high–risk pregnancies: The roles of working models and social support

Guided by both attachment and social support theories, the authors conducted a longitudinal investigation exploring the concomitant effects of perceptions of spouse support (anticipated and received spouse support) and internal working models of attachment (positive–self and positive–other), on childbearing depressive symptomatology. Distinct main and interaction effects for attachment dimensions and perceived support variables were hypothesized for high– and low–risk pregnancies. Participants in the final sample were 200 pregnant women who completed the self–report between the 25th and the 29th weeks of pregnancy, and 8 weeks after childbirth. Controlling for initial levels of depressive symptoms and health conditions, results demonstrated the protective role of high levels of received support and of positive–other models on childbirth depressive symptoms. Moreover, received support and models of positive–other were found to interact with health conditions, producing distinct moderation effects: Received support was found to be a significantly stronger protective factor for childbearing depression among women with low–risk pregnancies; positive–other models were found to be a significantly stronger protective factor among women with high–risk pregnancies. The implications of these findings for the understanding of intrapersonal and interpersonal factors in successful coping with a health risk situation are discussed.     

The Effect of Genetic Counseling on Knowledge and Perceptions Regarding Risks for Breast Cancer

In 1994, a clinic for cancer risk counseling was opened at Hadassah University Hospital in Jerusalem. Most of the counselees have been women who had breast cancer and/or a relative with breast cancer. In order to evaluate the effect of this counseling on women's knowledge and perceptions regarding the risks for breast cancer, a questionnaire was given before and after the counseling session to 60 healthy women who came to the clinic because they have relatives with breast cancer. According to the genetic counselors' estimations, most of these women had a significantly increased risk (compared to the general population) of developing cancer. Before counseling, the women overestimated the population risk for breast cancer, the contribution of heredity to morbidity of cancer, and their own risks to get cancer. After counseling session, they gave reduced estimates, closer to the real ones. The subjective perceptions regarding these risks were reduced after counseling, except for the perceptions regarding their relativerisks which have not changed after the counseling. About 90% of the women who came to the clinic wanted to be tested for genetic predisposition to cancer. For most of these women, the expectations that the test can rule out a genetic predisposition to cancer became more realistic after the counseling. The option to first test an affected relative was offered to all families, and a test was actually conducted in 75% of the families.     

Assessing the forms and functions of aggression using self-report: factor structure and invariance of the Peer Conflict Scale in youths

This study examined the structure of a self-report measure of the forms and functions of aggression in 855 adolescents (582 boys, 266 girls) aged 12 to 19 years recruited from high school, detained, and residential settings. The Peer Conflict Scale (PCS) is a 40-item measure that was developed to improve upon existing measures and provide an efficient, reliable, and valid assessment of four dimensions of aggression (i.e., reactive overt, reactive relational, proactive overt, and proactive relational) in youths. Confirmatory factor analyses showed that a 4-factor model represented a satisfactory solution for the data. The factor structure fit well for both boys and girls and across high school, detained, and residential samples. Internal consistency estimates were good for the 4 factors, and they showed expected associations with externalizing variables (i.e., arrest history, callous-unemotional traits, and delinquency). Reactive and proactive subtypes showed unique associations consistent with previous literature. Implications for the use of the PCS to assess aggression and inform intervention decisions in diverse samples of youths are discussed.     

Regulation of memory accuracy with multiple answers: the plurality option

We report two experiments that investigated the regulation of memory accuracy with a new regulatory mechanism: the plurality option. This mechanism is closely related to the grain-size option but involves control over the number of alternatives contained in an answer rather than the quantitative boundaries of a single answer. Participants were presented with a slideshow depicting a robbery (Experiment 1) or a murder (Experiment 2), and their memory was tested with five-alternative multiple-choice questions. For each question, participants were asked to generate two answers: a single answer consisting of one alternative and a plural answer consisting of the single answer and two other alternatives. Each answer was rated for confidence (Experiment 1) or for the likelihood of being correct (Experiment 2), and one of the answers was selected for reporting. Results showed that participants used the plurality option to regulate accuracy, selecting single answers when their accuracy and confidence were high, but opting for plural answers when they were low. Although accuracy was higher for selected plural than for selected single answers, the opposite pattern was evident for confidence or likelihood ratings. This dissociation between confidence and accuracy for selected answers was the result of marked overconfidence in single answers coupled with underconfidence in plural answers. We hypothesize that these results can be attributed to overly dichotomous metacognitive beliefs about personal knowledge states that cause subjective confidence to be extreme.     

Psychometric analysis of the Catalan version of the Alabama Parenting Questionnaire (APQ) in a community sample

The aim of this study was to adapt to Catalan the parents' and children's global report forms of the Alabama Parenting Questionnaire (APQ), using a community sample of 364 children between 10 and 15 years old and their families. Sociodemographic information (from parents) and the presence of externalizing problems (from parents and teachers) were collected. The results suggest a 3-factor structure corresponding to the scales of Positive Parenting Practices (PPP), Inconsistent and Negative Discipline (IND) and Poor Monitoring/Supervision (PMS). The internal consistency is acceptable in all the scales, except for the IND in the children's format. The scales also present good convergent and discriminant validity, and the relations with the external variable studied pointed in the expected direction: inefficient parenting practices are related to the presence of more behavior problems in children. To sum up, the Catalan version of the parents' and children's global report forms of the APQ are considered suitable for use in the area of children's and adolescents' behavior problems.
