Little research has evaluated open-ended parent reports to identify reinforcers for children with autism. This study evaluated open-ended parent reports and direct preference assessments for six young children with autism in home-based therapy. Results indicated little correspondence between parent reports and direct assessment assessments for all but one child. However, a follow-up reinforcer assessment with two children showed that the top ranked stimulus from both assessments functioned as reinforcers, with one child demonstrating higher levels of responding for the top ranked stimulus from the parent report. Results tentatively support open-ended parent reports to identify reinforcers for young children with autism.  相似文献

Many people who develop cancer symptoms wait inordinate amounts of time before seeking medical attention. Studies have found that symptom appraisal time–the time that passes before the individual concludes that their symptoms could be serious–accounts for most of the total delay time across subjects. It is thus important to understand the individual characteristics associated with slow recognition of dangerous symptoms. In this study, 62 patients (38 males) recently diagnosed with rectal cancer answered questions regarding the development of symptoms as well as their decisions and behaviors prior to seeking help. One subgroup of patients–males with the lowest scores on a measure of trait anxiety–took significantly longer to recognize the seriousness of their symptoms as compared to all other patients. This finding is discussed in the context of recent studies where the interaction of sex and negative affect is related to symptom reporting and other health-related behaviors.  相似文献

In order to develop scales representing curiosity-arousing components of pictures (slides) of either common objects or random shapes, a total of 56 college student Ss rated both sets of material on nine dimensions. Factor analyses indicated that the nine dimensions could be reduced to two factors. In order to test the ability of these factors to predict memorial performance and exploratory behavior, an additional 80 undergraduates were then tested for recognition or free looking time (FLT) of either object or random shape slides. Separate regression equations, using FLT and recognition performance as criterion measures, were computed. The present results not only indicate stability in visual exploratory scaling plus redundancy among various attributes of visual stimuli, but also suggest that behavior can be considered as elicited by two separate attributes of visual stimuli.  相似文献

The paper attempts some clarifications and differentiations concerning (1) Bick's classic distinction between states of helpless unintegration and states of defensive disintegration; (2) the difference between a state and a phase, and Bick's apparent challenge to some aspects of object relations thinking. The paper then lists some types of early pre-depressive and pre-Oedipal integrations and integrators: these include, as well as various kinds of containment, the role of the interested, interesting, and occasionally reclaiming object.  相似文献

The modified interfering cue theory put forward by Fletcher et al. (2) to explain performance in the ambiguous cue problem (ACP) was examined. Eight-year-old children were first trained to acquire response tendencies to the individual cues of this problem. When presented subsequently with the problem, the children showed marked differences in the number and type of errors made. The results were interpreted as supporting the theory of Fletcher et al. It was also suggested that the cues with clear positive or negative values were employed by the subjects to limit or neutralize the interference caused by the ambiguous cue.  相似文献

In everyday life, many probabilistic situations may be characterized as probabilistic waiting. A gambler, for example, bets repeatedly at the racetrack, the casino, or the card table. The gambler may not win on the first try, but if a gamble is repeated enough times, a win is almost certain to occur eventually. If repeated gambles are structured as strings of losses ending in a win (probabilistic waiting) and the amount won is discounted by the delay caused by the series of losses, then strings with many losses will be discounted more than those with fewer losses, thereby causing subjective value of the series of gambles as a whole to increase. The current study used the opposite effect that amount has on the degree of delay and probability discounting as a marker to determine whether people evaluate situations involving probabilistic waiting as they evaluate situations involving delayed outcomes or as situations involving probabilistic outcomes. We find that the more likely a probabilistic waiting situation is to end in reward (e.g., a gamble is repeated indefinitely until reward is obtained), the more that situation conforms to delay discounting; the less likely a probabilistic waiting situation is to end in reward (e.g., a fixed, small number of gambles), the more that situation conforms to probability discounting. We argue that the former situation is applicable to pathological gambling, and that people with steep delay discount functions would therefore be more likely to have gambling problems.

Delay discounting—preference for immediate, smaller rewards over distal, larger rewards—has been argued to be part of the “generality of deviance”, which describes the co‐occurrence of various forms of impulsive and risky behaviors among individuals. Some studies have linked laboratory‐measured delay discounting to behaviors, traits, attitudes, and outcomes associated with risk, but these associations have been inconsistent. Furthermore, many of these studies have been conducted with exclusively undergraduate samples, or in samples offering low statistical power. In a large community sample (n = 328) diverse in age and socioeconomic status, we examined associations between two measures of behavioral delay discounting (single‐shot and canonical k‐parameter estimation) and behavioral risk‐taking, personality traits associated with risk, domain‐specific risk attitudes, gambling and problem gambling, antisocial behavior, and criminal outcomes. In addition, we explored whether a novel response time latency measure of delay discounting explained variance in these risk‐related outcomes. Results indicated that behavioral delay discounting was consistently associated with all variables related to impulse control: high trait impulsivity, low trait self‐control, risk‐averse attitudes toward financial investment, risk‐prone attitudes toward gambling and health/safety risks, gambling and problem gambling, antisocial conduct, and criminal outcomes. Latency‐measured delay discounting was inconsistently associated with behavioral delay discounting and risk‐related measures. Together, results suggest that delay discounting is associated with poor impulse control consistent with a generality of deviance account. Copyright © 2016 John Wiley & Sons, Ltd.  相似文献
