Choice in a self-control paradigm: Quantification of experience-based differences 总被引:14,自引:14,他引:0 下载免费PDF全文

Previous quantitative models of choice in a self-control paradigm (choice between a larger, more-delayed reinforcer and a smaller, less-delayed reinforcer) have not described individual differences. Two experiments are reported that provide additional quantitative data on experience-based differences in choice between reinforcers of varying sizes and delays. In Experiment 1, seven pigeons in a self-control paradigm were exposed to a fading procedure that increased choices of the larger, more-delayed reinforcer through gradually decreasing the delay to the smaller of two equally delayed reinforcers. Three control subjects, exposed to each of the small-reinforcer delays to which the experimental subjects were exposed, but for fewer sessions, demonstrated that lengthy exposure to each of the conditions in the fading procedure may be necessary in order for the increase to occur. In Experiment 2, pigeons with and without fading-procedure exposure chose between reinforcers of varying sizes and delays scheduled according to a concurrent variable-interval variable-interval schedule. In both experiments, pigeons with fading-procedure exposure were more sensitive to variations in reinforcer size than reinforcer delay when compared with pigeons without this exposure. The data were described by the generalized matching law when the relative size of its exponents, representing subjects' relative sensitivity to reinforcer size and delay, were grouped according to subjects' experience. 相似文献

Organizational citizenship behavior (OCB) is assessed by measuring how frequently employees display extra-role and discretionary behaviors. One hundred forty-four managerial employees responded to an OCB scale and indicated the number of behaviors on the scale they believed to be formally evaluated. None of the behaviors were believed to be unevaluated by all employees. Data suggest that a typical OCB scale is not measuring citizenship behaviors for everybody, and that OCB measurement needs refinement. Best prediction of other organizational variables was obtained when both the OCB and an index of "unevaluated" behaviors were used as predictors. Supervisor fairness interacted with OCB when predicting organizational commitment, and this interaction was contingent on the extent OCBs were believed to be unevaluated. 相似文献

Toddlers' use of effective attention deployment strategies to cope with separation from the mother and with maternal behavior predicted the use of effective delay-of-gratification strategies at age 5, even though the contexts, measures, and manifest behaviors were different. Toddlers who used distraction strategies during a brief separation from the mother were able, at age 5, to delay immediate gratification longer for more valued rewards. Toddlers who explored at a distance from a controlling mother when she tried to engage the child also delayed longer and used more effective delay strategies at age 5, compared with toddlers who did not distance themselves. Toddlers whose mothers were not controlling showed the opposite pattern: Those who did not distance themselves from the mother's bids had longer preschool delay times and more effective strategies. Strategic attention deployment was shown to be an enduring self-regulatory skill visible in early development across domains, measures, and over time. 相似文献

Borderline personality disorder (BPD) features have been linked to deficits in mindfulness, or nonjudgmental attention to present-moment stimuli. However, no previous work has examined the role of fluctuations in mindfulness over time in predicting BPD features. The present study examines the impact of both between-person differences and within-person changes in mindfulness. 40 women recruited to achieve a flat distribution of BPD features completed 4 weekly assessments of mindfulness (Five Facet Mindfulness Questionnaire; FFMQ) and BPD features. Multilevel models predicted each outcome from both 1) a person’s average levels of each facet and 2) weekly deviations from a person’s average for each facet. Average acting with awareness, nonjudging, and nonreactivity predicted lower BPD features at the between-person level, and weekly deviations above one’s average (i.e., higher-than-usual) nonjudging predicted lower BPD feature expression at the within-person level. Within-person fluctuations in the nonjudging facet of mindfulness may be relevant to the daily expression of BPD features over and above dispositional mindfulness. 相似文献

Younger sisters of teenage parents have elevated rates of engaging in unprotected sex. This may result from changes in parenting behavior after a sibling becomes pregnant or impregnates a partner, and be particularly pronounced for girls seeking mental health treatment. The current study examines condom use over time in 211 African-American girls recruited from outpatient psychiatric clinics. Findings indicate that having a sibling with a teenage pregnancy history predicts less consistent condom use 2 years later. After accounting for earlier condom use and mental health problems, maternal monitoring moderates condom use such that for girls with a sibling with a pregnancy history, more vigilant maternal monitoring is associated with increased condom use, while for girls with no sibling pregnancy history, maternal monitoring is unrelated to adolescents’ condom use 2 years later. Findings suggest that targeted interventions to increase maternal monitoring of high-risk teens may be beneficial for girls with a sibling history of teenage pregnancy. 相似文献

On the Importance of Family,Morality, Masculine,and Feminine Honor for Theory and Research 下载免费PDF全文
Patricia M. Rodriguez Mosquera 《Social and Personality Psychology Compass》2016,10(8):431-442
This paper presents an approach to honor as multifaceted. In this approach, honor is defined as having four different facets, or honor codes: morality‐based honor, family honor, masculine honor, and feminine honor. The honor‐as‐multifaceted approach has generated much psychological research examining the importance of each honor code across different cultural and social groups. An overview of this research shows that that the different honor codes exert a powerful influence on a variety of group processes, including collective action, in‐group identification, the definition of gendered roles within the family, in‐group responses to threats to collective honor, intergroup attitudes, and value change within groups. The paper discusses how defining and measuring honor as multifaceted ‐rather than as an unitary construct‐ provides a fuller understanding of honor's role in group life. 相似文献

The neuropathological correlates of suicide in older persons have received little research attention. Our recent study of elderly suicide victims from an Australian forensic medicine department (n = 143), unlike a previous case-control study, did not find an increased prevalence of Alzheimer's disease (AD) in older persons who committed suicide despite a history of dementia in 6.3%. Both studies were limited to the examination of AD-related pathology by the availability of tissue. We present clinicopathological data on three cases from our study for whom autopsy findings were available. These cases included: a community-dwelling male in his early eighties with dementia who was found to have multiple cortical and striatal lacunes and glial scars, small vessel cerebrovascular disease (SVD) and AD-related pathology; a community-dwelling male in his mid-seventies with depression and loss of concentration, with brainstem predominant Lewy body disease (LBD) and AD-related pathology; and a female nursing home resident in her nineties with a history of stroke and prior suicide attempts who was found to have infarcts and SVD in frontal regions. Neuropathological findings in elderly suicide victims may include multiple neurodegenerative pathologies. The burden and distribution of neurodegenerative diseases apart from AD, including SVD and LBD, should be assessed as possible pathophysiological factors contributing to late life suicide. 相似文献

Previous research investigating attention and impulse control in individuals with Attention-Deficit/Hyperactivity Disorder (ADHD) has largely ignored the symptomatic differences among the three subtypes of ADHD: ADHD-Inattentive Type, ADHD-Hyperactive/Impulsive Type, and ADHD-Combined Type. The present study examined attention and impulse control by focusing on these subtypes. Based on their self-reported symptoms of ADHD, participants belonged to one of four groups: ADHD-Inattentive, ADHD-Hyperactive/Impulsive, ADHD-Combined, and control. Cortical activity was recorded from participants during performance of a Go/NoGo task. The event-related potentials (ERP) measured at frontal and posterior sites discriminated between the control group and participants with symptoms of ADHD. The control group consistently exhibited a higher P3 amplitude than all the ADHD groups. The main difference occurred at the frontal site, indicating that individuals with ADHD symptoms have deficits in the anterior attentional system, which mediates signal detection. Behavioral measures of signal sensitivity revealed that the ADHD-Inattentive and the ADHD-Hyperactive/Impulsive groups had more difficulty with the attention-demanding Go/NoGo respond-to-target task, while behavioral measures of response bias indicated that the ADHD-Hyperactive/Impulsive and the ADHD-Combined groups responded more liberally in the inhibition-demanding Go/NoGo suppress-to-target task. 相似文献

The Relation Between Anxiety Sensitivity and Attachment Style in Adolescence and Early Adulthood 总被引:2,自引:0,他引:2

Given the accumulating evidence for a role of anxiety sensitivity in the etiology of panic, it is important to understand the developmental origins of anxiety sensitivity. To this end, this study examined the relation between attachment beliefs and anxiety sensitivity in a sample of high school students (n = 203; mean age 15.7 years) and university students (n = 324; mean age 21.7 years). The Experiences in Close Relationships (ECR; K. Brennan, C. Clark, &; P. Shaver, 1998) was used to assess attachment beliefs and to classify participants into attachment groups. The Anxiety Sensitivity Index (ASI; R. A. Peterson &; S. Reiss, 1987) was used to assess participants' levels of anxiety sensitivity. Results supported the hypothesis that individuals with insecure attachment, specifically those classified as preoccupied and fearful (i.e., those with a negative model of self), had significantly higher anxiety sensitivity scores than securely attached individuals in both the high school and college samples. 相似文献
