The hypothesis that sex differences in spatial visualization ability might account for sex differences in mathematical ability was supported for a group of 183 male and 81 female college students. With spatial visualization statistically controlled, no significant sex differences in Quantitative Scholastic Aptitude Test (QSAT) scores was found; including sex as a predictor variable increased the variance explained by less than 1%. Although the slope of the regression of mathematics on spatial visualization did not differ as a function of sex, males were somewhat more predictable than females. As the OSAT of both males and females high on spatial visualization was more predictable than the QSAT of those scoring less well, it appears that the sex difference in predictability is due to males having higher spatial ability than females. 相似文献

Severely retarded, blind children were conditioned to respond differentially to two intensities of a pure tone. Gradients of auditory generalization were obtained that were reliable and similar to those for normal adults, but often asymmetric and non-monotonic. 相似文献

People are often taught using a combination of instruction and practice. In prior research, we have distinguished between model-based knowledge (i.e., acquired from explicit instruction) and experience-based knowledge (i.e., acquired from practice), and have argued that the issue of how these types of knowledge (and associated learning processes) interact has been largely neglected. Two experiments explore this issue using a dynamic control task. Results demonstrate the utility of providing model-based knowledge before practice with the task, but more importantly, suggest how this information improves learning. Results also show that learning in this manner can lead to "costs" such as slowed retrieval, and that this knowledge may not always transfer to new task situations as well as experientially acquired knowledge. Our findings also question the assumption that participants always acquire a highly specific "lookup" table representation while learning this task. We provide an alternate view and discuss the implications for theories of learning. 相似文献

To what extent do speaker-external communicative pressures versus speaker-internal cognitive pressures affect utterance form? Four experiments measured speakers' references to privately known (i.e., privileged) objects when naming mutually known (i.e., common ground) objects. Although speaker-external communicative pressures demanded that speakers avoid references to privileged objects, 2 experiments showed that speakers often ignored this demand when it coexisted with a speaker-internal pressure to attend to those privileged objects. The authors hypothesize that this was due to increased salience of privileged objects (a speaker-internal pressure). Experiment 3 showed that directly boosting the salience of privileged objects increased the likelihood that speakers will inappropriately refer to those objects. Experiment 4 showed that the salience-sensitive mechanism in Experiments 1 and 2 is likely related to the mechanism causing such references in Experiment 3. Thus, the language production system is especially sensitive to cognitive pressures even when communicative harm results. 相似文献

A medical center-based forensic clinic that provides the necessary comprehensive consultation, continuing education, court testimony, and clinical services through an applied model of teleconferencing applications is addressed. Telemedicine technology and services have gained the attention of both legal and clinical practitioners, examining trends and models of health care for underserved populations, and identifying where consultation with a team of professionals may benefit service providers in rural communities. The contribution offered herein provides an understanding of the history of the development of the clinic, a theoretical model that has been applied to a clinical forensic program that employs telepsychiatry services, and the ethical and malpractice liability issues confronted in using teleconferencing services. This model is examined through a child and adolescent forensic evaluation clinic. The goals of this model are offered, as are a number of applications within the broad spectrum of services utilizing telemedicine. Finally, changing patterns are addressed in clinically based health-care delivery for criminal justice, social services, and forensic mental health. 相似文献

Vital exhaustion has been implicated in the development and progression of cardiovascular disease. In addition, elevated levels of fibrinogen and D-dimer have been associated with an increased risk of cardiovascular disease. Some studies have suggested that fibrinogen and D-dimer are associated with acute, chronic, and perceived stress. In this issue, Kudielka et al examine the relationship between circulating fibrinogen and D-dimer levels and vital exhaustion in a cross-sectional study of middle-aged teachers in Germany, to examine the plausible link between chronic stress and the development of cardiovascular disease. This commentary discusses the limited available evidence of the mechanisms responsible for the association between vital exhaustion and the development of cardiovascular disease and highlights the limitations of previous research and discusses future directions. 相似文献

This research examines the relationship between childhood physical and sexual abuse and the types of crimes committed by male adult offenders. We use the method of discriminant prediction to determine whether independent and dependent variables are related in ways that theories predict. Our analyses of data from the Survey of Inmates in State and Federal Correctional Facilities suggest that offenders model specific behaviors to which they have been exposed. Male offenders who were sexually abused as a child are more likely to commit sexual offenses, particularly sexual offenses against children, than nonsexual offenses. Offenders who were physically abused are more likely to engage in violent offenses than nonviolent offenses. Further analyses show that sexual offenders, and to a lesser extent violent offenders, are likely to specialize in those offenses. Our results are consistent with a social learning approach. They address a heretofore neglected issue: what exactly do children model when they are mistreated. Aggr. Behav. 35:489–501, 2009. © 2009 Wiley‐Liss, Inc. 相似文献

Age differences in emotion recognition from lexical stimuli and facial expressions were examined in a cross-sectional sample of adults aged 18 to 85 (N = 357). Emotion-specific response biases differed by age: Older adults were disproportionately more likely to incorrectly label lexical stimuli as happiness, sadness, and surprise and to incorrectly label facial stimuli as disgust and fear. After these biases were controlled, findings suggested that older adults were less accurate at identifying emotions than were young adults, but the pattern differed across emotions and task types. The lexical task showed stronger age differences than the facial task, and for lexical stimuli, age groups differed in accuracy for all emotional states except fear. For facial stimuli, in contrast, age groups differed only in accuracy for anger, disgust, fear, and happiness. Implications for age-related changes in different types of emotional processing are discussed. 相似文献
