A common response bias in psychophysical judgments is regression toward the mean (overestimation of small and underestimation of large values, or the response contraction bias). The same bias is observed in magnitude estimation from memorized quantities. Participants estimated alphabetic interval distances between 2 letters for different levels of interletter distances. The underestimated and overestimated values and the point of least error changed, depending on the level of alphabetic distances judged; furthermore, their estimation showed a progressively increasing tendency toward the mean, rendering the estimation progressively less accurate as the estimation task was repeated. We conclude that the regression toward the mean in memorial quantifying judgment derives from a cognitive adaptation process rather than from a permanent, compressed memory representation of the stimuli. Two opposing views on the adaptive meaning of this judgment bias are discussed. 相似文献

Over the past decade, behavior analysts have increasingly used the term establishing operation (EO) to refer to environmental events that influence the behavioral effects of operant consequences. Nonetheless, some elements of current terminology regarding EOs may interfere with applied behavior analysts' efforts to predict, control, describe, and understand behavior. The present paper (a) describes how the current conceptualization of the EO is in need of revision, (b) suggests alternative terms, including the generic term motivating operation (MO), and (c) provides examples of MOs and their behavioral effects using articles from the applied behavior analysis literature. 相似文献

B. F. Skinner's Science and Human Behavior (1953) became the main source of my understanding of behavior during my first semester as a college professor in 1955 at Kansas University. It has continued to exert a major influence throughout my career as the basis for a completely deterministic science of behavior, as a handbook to be consulted as a first step in dealing with any issue in behavior analysis, and as a tutorial in behavioral interpretive analysis--in the use of a small number of behavioral concepts and principles to understand behavior of all degrees of complexity. I describe four general interpretive orientations or maxims that are of broad significance for behavior analysis, and also two underappreciated major theoretical contributions. 相似文献

Temporal integration of speech prosody is shaped by language experience: an fMRI study 总被引:5,自引:0,他引:5

Differences in hemispheric functions underlying speech perception may be related to the size of temporal integration windows over which prosodic features (e.g., pitch) span in the speech signal. Chinese tone and intonation, both signaled by variations in pitch contours, span over shorter (local) and longer (global) temporal domains, respectively. This cross-linguistic (Chinese and English) study uses functional magnetic resonance imaging to show that pitch contours associated with tones are processed in the left hemisphere by Chinese listeners only, whereas pitch contours associated with intonation are processed predominantly in the right hemisphere. These findings argue against the view that all aspects of speech prosody are lateralized to the right hemisphere, and promote the idea that varying-sized temporal integration windows reflect a neurobiological adaptation to meet the 'prosodic needs' of a particular language. 相似文献

Rogers JR 《Suicide & life-threatening behavior》2003,33(1):9-20
Suicidologists have made tremendous strides in advancing the knowledge of correlates of completed suicide and nonfatal suicidal behavior since the early 1960s. In order to move beyond the simple identification of risk factors, however, scientific suicidology needs to give greater attention to the critical role of theory in guiding inquiry and advancing the understanding of suicidal behaviors. In this article I argue the importance of theoretical grounding from the perspective of psychological science, provide examples of this perspective from my work, and discuss their implications for future research in the field. 相似文献

Now you feel it, now you don't: frontal brain electrical asymmetry and individual differences in emotion regulation 总被引:6,自引:0,他引:6

Recent theoretical accounts of emotion regulation assign an important role in this process to the prefrontal cortex, yet there is little relevant data available to support this hypothesis. The current study assessed the relation between individual differences in asymmetric prefrontal activation and an objective measure of uninstructed emotion regulation. Forty-seven participants 57 to 60 years old viewed emotionally arousing and neutral visual stimuli while eyeblink startle data were collected. Startle probes were also presented after picture presentation to capture the persistence or attenuation of affect following the offset of an emotional stimulus. Subjects with greater relative left-sided anterior activation in scalp-recorded brain electrical signals displayed attenuated startle magnitude after the offset of negative stimuli. This relation between resting frontal activation and recovery following an aversive event supports the idea of a frontally mediated mechanism involved in one form of automatic emotion regulation. 相似文献

The incarceration of mentally ill youth is a serious problem not receiving the same attention as in adults. In this study, we examine the prevalence of psychopathology and level of behavioral symptomatology in incarcerated youth versus youth receiving community mental health services or hospitalization. We randomly recruited youth from middle South Carolina served by a local CMHC (n = 60), youth served by the state adolescent inpatient program (n = 50), and youth in the S.C. Dept. of Juvenile Justice facilities from the same region (n = 75). We used the DISC-PC 2.3 to evaluate DSM-III-R diagnoses and the CBCL and YSR to evaluate behavioral symptomatology. On the DISC, incarcerated youth had significantly higher mean number of diagnoses and symptoms than CMHC youth, but lower numbers than hospitalized youth. Level of caseness (at least one diagnosis) was 86% in hospital youth, 72% in incarcerated youth, and 60% in CMHC youth. The groups differed in CBCL mean total T, internalizing T, and externalizing T scores as well as mean YSR internalizing T scores. Our results indicate the comparability in level of psychopathology in incarcerated and community-treated populations of youth, and the need to develop diversionary programs to prevent the entry of such youth into the juvenile justice system. 相似文献

In two experiments testing age differences in the subjective experience of listening, which we call meta-audition, young and older adults were first trained to learn pairs of semantic associates. Following training, both groups were tested on identification of words presented in noise, with the critical manipulation being whether the target item was congruent, incongruent, or neutral with respect to prior training. Results of both experiments revealed that older adults compared to young adults were more prone to "false hearing," defined as mistaken high confidence in the accuracy of perception when a spoken word had been misperceived. These results were obtained even when performance was equated across age groups on control items by reducing the noise level for older adults. Such false hearing is shown to reflect older adults' heavier reliance on context. Findings suggest that older adults' greater ability to benefit from semantic context reflects their bias to respond consistently with the context, rather than their greater skill in using context. Procedures employed are unique in measuring the subjective experience of hearing as well as its accuracy. Both theoretical and applied implications of the findings are discussed. Convergence of results with those showing higher false memory, and false seeing are interpreted as showing that older adults are less able to constrain their processing in ways that are optimal for performance of a current task. That lessened constraint may be associated with decline in frontal-lobe functioning. 相似文献

Research on feigned mental disorders indicates that severe psychopathology coupled with significant trauma histories often complicate feigning determinations, resulting in inaccuracies on otherwise effective measures. As part of malingering assessments, the Personality Assessment Inventory (PAI) is often used because of its excellent validation and the availability of three feigning indicators (Negative Impression, Malingering Index, and Rogers Discriminant Function), which have evidenced large effect sizes and clinically useful cut scores. The current study examined the effectiveness of the PAI in a traumatized inpatient sample using a between-subjects simulation design. Although Negative Impression appeared affected by trauma--especially in conjunction with dissociative symptoms--very positive results were found for Malingering Index and Rogers Discriminant Function. They remained relatively unelevated under honest conditions, despite posttraumatic stress disorder and extensive comorbidity. Using single-point cut scores provided moderately good classification of feigned and genuine PAI profiles. For purposes of classification, the authors operationally defined small indeterminate groups that were considered too close to classify (i.e., ±5T of the cut scores). With indeterminate cases removed, the overall classification rates improved modestly. However, the more important finding involved the error rates for the indeterminate group, which exceeded 50%. Directions for further research are discussed. 相似文献

Data from 167 participants were used to establish the psychometric properties of the Reidhead spiritual integration scale, 31-item version (SI-31). Structural equation modeling was used to empirically evaluate influences on perceived health functioning, while accounting for possible confounds. The analyses showed that SI-31 predicted perceived mental and physical health while controlling for life satisfaction, religious variables, mood patterns, depression symptoms, and demographics. The importance of SI as a predictor of health-related outcomes is supported, as is the usefulness of the SI-31 in predicting these outcomes. 相似文献
