ABSTRACT— Proponents of unconscious-thought theory assert that letting the unconscious "mull it over" can enhance decisions. In a series of recent studies, researchers demonstrated that participants whose attention was focused on solving a complex problem (i.e., those using conscious thought) made poorer choices, decisions, and judgments than participants whose attention was distracted from the problem (i.e., those purportedly using unconscious thought). We argue that this finding, rather than establishing the existence of a deliberation-without-attention effect, is explained more compellingly in terms of the well-established distinction between on-line and memory-based judgments. In Experiment 1 , we reversed the recent finding by simply changing participants' on-line processing goal from impression formation to memorization. Experiment 2 provided a replication and further established that some cognitive effort appears necessary to produce both the original pattern of results and its reversal, suggesting that such judgments are ultimately a product of conscious, rather than unconscious, thinking. 相似文献

This study describes changes over a 36-month period in the lives of children of probationers who were subjects of reports
of maltreatment. Data on a nationally representative sample of reported victims of maltreatment were used to examine probationer-parents’
contact with the criminal justice system, and concurrent changes in their children’s households, risk exposure, and emotional
and behavioral problems. Results show that 36 months after coming in contact with the child welfare system, about 40% of probationer’s
children no longer lived with their probationer-parents. During the same period, children’s exposure to risk (i.e., parental
substance abuse, mental illness, and domestic violence) dropped markedly; however, there was an upward trend in the prevalence
of child emotional and behavioral problems. These problems ultimately declined among very young children, but persisted among
elementary school age children. Further prospective studies are needed to better understand the confluence of factors affecting
the outcomes of probationers’ children. 相似文献

Three previous psychophysical studies have demonstrated that interaural time difference (ITD) coding mechanisms can undergo frequency-specific, selective adaptation. We sought to determine whether this phenomenon extends to the pitch domain, by employing the same psycho-physical paradigm as one used previously, but with harmonic tone complexes lacking energy at the fundamental frequency. Ten normal listeners participated in experiment 1. Psychometric functions for ITDs were obtained for harmonic tone complexes with fundamental frequencies of 110 Hz and 185 Hz, before and after selective adaptation with complexes of the same fundamental frequencies lateralised to opposite sides. In experiment 1, each subject was tested twice. On separate days, subjects were tested with 110 Hz and 185 Hz stimuli that were either partially resolvable complexes or unresolvable ones. Both partially resolved and unresolved stimuli supported adaptation, and at both fundamental frequencies. In experiment 2, which employed nine listeners, the adaptor tone complexes were presented in conjunction with a diotic noise background designed to mask difference tones generated by the adaptor stimuli. The use of the masker had little effect on the mean strength of the adaptation effected by the unresolved adaptor stimuli, and only slightly weakened the adaptation effect found with the partially resolved adaptor stimuli. Taken together, these data constitute the first demonstration of selective adaptation exerted on a central mechanism in the pitch domain. 相似文献

Adults described and dated two kinds of personal remembrances: a fragment—a memory moment that is largely bereft of context—and an episodic, personal event memory—a narrative that consists of a number of related events. In Experiment 1 subjects reported memories from when they were 0–8 years of age and in Experiment 2, from when they were 0–16 years of age. Fragments were judged to be older than event memories, especially in Experiment 2 where the estimated ages of most fragments were from 0 to 8 years and of most episodic memories, from 8 to 16 years. Ratings of various features of the two kinds of memories also differed. We conclude that isolated memory moments possess validity and that although they are most likely to arise when the autobiographical memory system is not fully developed, they can also originate during a time when it is.

Wachtel's article is as relevant today as it was over a quarter century ago, especially as public support for higher education has declined, and increased pressure to obtain external research funding is needed in order to support universities. Although Wachtel's observation that research and grant funding are more likely to be reinforced then theoretical inquiry, there is a serious question regarding whether theory can be effective in advancing the field of psychology and psychotherapy. Some of problems that typically have been associated with theory in our field are discussed, and the argument is made that theoretical inquiry be directed to the formulation of less abstract and more focal principles of human behavior and the therapy change process. 相似文献

The authors considered compliance with a decision aid that E. Thorp (1966) designed to minimize loss in a gambling paradigm under different levels of risk or impairment. Twenty adult men (aged 18-46) completed the South Oaks Gambling Screen (SOGS; H.R. Lesieur & S. B. Blume, 1987) and the Alcohol Use Disorders Identification Test (AUDIT; J. P. Allen, D. E Reinert, & R. J. Volk, 2001) and then played a computer blackjack program before and after ingesting alcohol. The decision aid (online Basic advice) increased players' compliance with optimal play and also increased players willingness to wager more at high stakes. Participants attained a mean peak blood alcohol concentration (BAC) of 0.048%. Alcohol increased the rate of play. After consuming alcohol, participants appeared to spend less time on their decisions and were more reliant on support. The authors explained these results in terms of an alcohol-induced myopia that enhances responses to salient cues. 相似文献

Predictive visual context facilitates visual search, a benefit termed contextual cuing (M. M. Chun & Y. Jiang, 1998). In the original task, search arrays were repeated across blocks such that the spatial configuration (context) of all of the distractors in a display predicted an embedded target location. The authors modeled existing results using a connectionist architecture and then designed new behavioral experiments to test the model's assumptions. The modeling and behavioral results indicate that learning may be restricted to the local context even when the entire configuration is predictive of target location. Local learning constrains how much guidance is produced by contextual cuing. The modeling and new data also demonstrate that local learning requires that the local context maintain its location in the overall global context. 相似文献

Noncontingent reinforcement (NCR) is a commonly used treatment for severe problem behavior displayed by individuals with intellectual and developmental disabilities. The current study sought to extend the literature by reporting outcomes achieved with 27 consecutive applications of NCR as the primary treatment for severe problem behavior. All applications of NCR were included regardless of treatment outcome to minimize selection bias favoring successful cases. Participants ranged in age from 5 to 33 years. We analyzed the results across behavioral function and with regard to the use of functional versus alternative reinforcers. NCR effectively treated problem behavior maintained by social reinforcement in 14 of 15 applications, using either the functional reinforcer or alternative reinforcers. When we implemented NCR to treat problem behavior maintained by automatic reinforcement, we often had to add other treatment components to produce clinically significant effects (five of nine applications). Results provide information on the effectiveness and limitations of NCR as treatment for severe problem behavior. 相似文献

We compared 2 rating scales with different manic symptom items on diagnostic accuracy for detecting pediatric bipolar spectrum disorder (BPSDs) in outpatient mental health clinics. Participants were 681 parents/guardians of eligible children (465 male, mean age = 9.34) who completed the Parent General Behavior Inventory-10-item Mania (PGBI-10 M) and mania subscale of the Child and Adolescent Symptom Inventory-Revised (CASI-4R). Diagnoses were based on KSADS interviews with parent and youth. Receiver operating characteristic (ROC) analyses and diagnostic likelihood ratios (DLRs) determined discriminative validity and provided clinical utility, respectively. Logistic regressions tested for incremental validity in the CASI-4R mania subscale and PGBI-10 M in predicting youth BPSD status above and beyond demographic and common diagnostic comorbidities. Both CASI-4R and PGBI-10 M scales significantly distinguished BPSD (N = 160) from other disorders (CASI-4R: Area under curve (AUC) = .80, p < 0.0005; PGBI-10 M: AUC = 0.79, p < 0.0005) even though scale items differed. Both scales performed equally well in differentiating BPSDs (Venkatraman test p > 0.05). Diagnostic likelihood ratios indicated low scores on either scale (CASI: 0–5; PGBI-10 M: 0–6) cut BPSD odds to 1/5 of those with high scores (CASI DLR- = 0.17; PGBI-10 M DLR- = 0.18). High scores on either scale (CASI: 14+; PGBI-10 M: 20+) increased BPSD odds about fourfold (CASI DLR+ = 4.53; PGBI-10 M DLR+ = 3.97). Logistic regressions indicated the CASI-4R mania subscale and PGBI-10 M each provided incremental validity in predicting youth BPSD status. The CASI-4R is at least as valid as the PGBI-10 M to help identify BPSDs, and can be considered as part of an assessment battery to screen for pediatric BPSDs. 相似文献
