Implicit,long-term spatial contextual memory   总被引:4,自引:0,他引:4  
Learning and memory of novel spatial configurations aids behaviors such as visual search through an implicit process called contextual cuing (M. M. Chun & Y. Jiang, 1998). The present study provides rigorous tests of the implicit nature ofcontextual cuing. Experiment 1 used a recognition test that closely matched the learning task, confirming that memory traces of predictive spatial context were not accessible to conscious retrieval. Experiment 2 gave explicit instructions to encode visual context during learning, but learning was not improved and conscious memory remained undetectable. Experiment 3 illustrates that memory traces for spatial context may persist for at least 1 week, suggesting along-term component of contextual cuing. These experiments indicate that the learning and memory of spatial context in the contextual cuing task are indeed implicit. The results have implications for understanding the neural substrate of spatial contextual learning, which may depend on an intact medial temporal lobe system that includes the hippocampus (Mi. M. Chun & E. A. Phelps, 1999).  相似文献

Nicolosi and Byrd in 2002 summarized empirical research on birth order and sexual orientation in men, which research has documented that homosexual men have a later birth order than heterosexual men. They did not, however, note a more refined analysis of an earlier null finding by Siegelman. This 1998 reanalysis by Blanchard, Zucker, Siegelman, Dickey, and Klassen also confirmed the later birth order of homosexual men.  相似文献

There is a strong assumption of intergenerational continuity in behavior patterns, including antisocial behavior. Using a 3-generation, prospective study design, we examine the level of behavioral continuity between Generation 2 (G2) and Generation 3 (G3), and the role of economic disadvantage and parenting behaviors as mediating links. We estimate separate models for G2 fathers and G2 mothers. Data are drawn from the Rochester Youth Development Study, a longitudinal study begun in 1988 during G2's early adolescence (n = 1,000), which has collected prospective data on G2, their parents (G1), and now their G3 children. Results show that intergenerational continuity in antisocial behavior is evident, albeit somewhat modest. Parenting styles and financial stress do play a mediating role, although their effects vary by G2's gender. In general, adolescent delinquency plays a larger role in linking the generations for G2 fathers, whereas parenting behaviors and financial stress play a larger role for G2 mothers.  相似文献

Mental health consumer advocates have long argued that involuntary treatment frightens persons with mental disorder and thus deters them from voluntarily seeking help. We surveyed 85 mental health professionals and 104 individuals with schizophrenia spectrum conditions to assess their experience with and perceptions of involuntary treatment and other treatment mandates. Of the clinicians, 78% reported that overall they thought legal pressures made their patients with schizophrenia more likely to stay in treatment. Regarding involuntary outpatient commitment, 81% of clinicians disagreed with the premise that mandated community treatment deters persons with schizophrenia from seeking voluntary treatment in the future. Of the consumer sample, 63% reported a lifetime history of involuntary hospitalization, while 36% reported fear of coerced treatment as a barrier to seeking help for a mental health problem-termed here "mandated treatment-related barriers to care." In bivariate analyses, reluctance to seek outpatient treatment associated with fear of coerced treatment (mandated treatment-related barriers to care) was significantly more likely in subjects with a lifetime history of involuntary hospitalization, criminal court mandates to seek treatment, and representative payeeship. However, experience with involuntary outpatient commitment was not associated with barriers to seeking treatment. Recent reminders or warnings about potential consequences of treatment nonadherence, recent hospitalization, and high levels of perceived coercion generally were also associated with mandated treatment-related barriers to care. In multivariable analyses, only involuntary hospitalization and recent warnings about treatment nonadherence were found to be significantly associated with these barriers. These results suggest that mandated treatment may serve as a barrier to treatment, but that ongoing informal pressures to adhere to treatment may also be important barriers to treatment.  相似文献

Survival-related clinical reports are abundantly found in the works of classical, object-relational, and self psychological writers, but are underrepresented in major theoretical formulations on anxiety. Fears of being overwhelmed, merged, penetrated, fragmented, and destroyed, as contents of unconscious and conscious fantasies, are regularly interrelated with the typical dangers. Fifteen preliminary propositions invite closer study of such apprehensions and provide definitional components. Annihilation anxieties are triggered by survival threat; are found early but can be engendered throughout the life cycle; constitute a basic danger; are residuals of psychic trauma; have specifiable subdimensions; may occur in presymbolic form or be associated with fantasies in conflict/compromise formation; may arise with or without anticipation; may be accompanied by controlled or uncontrolled anxiety; are motives for defense; and may be associated with particularly recalcitrant resistances. The study of annihilation anxieties in relation to the basic danger series has both theoretical and clinical advantages, especially for understanding traumatic, anxiety, phobic, psychosomatic, addictive, narcissistic, borderline, and psychotic manifestations, as well as sexual problems (including perversions), nightmares, dissociative and panic states, and especially difficult resistances.  相似文献

Credibility has been proposed recently as a standard for assessing the value of policy analysis. While various strategies for enhancing the credibility of policy analysis are available, little evidence exists concerning to what extent and under what circumstances implementing such strategies does, in fact, increase the value of policy analysis in terms of improving organizational decisionmaking. In this paper computer simulation—a methodological approach that has not been widely used to date in the field of knowledge application—is used to begin, to fill this gap. Specifically, the “garbage-can” model of decisionmaking developed by Cohen, March and Olsen (1972) has been modified to reflect a possible contribution of policy analysis to decisionmaking. Using this model, the extent to which enhancing credibility results in improved organizational decisionmaking under various circumstances is examined. Marvin B. Mandell is an assistant professor of policy sciences at the University of Maryland Baltimore County. His present research is focused on quantitative techniques for policy analysis and evaluation and the use of analytical information in decisionmaking.  相似文献

The phenomenon of ‘chasing' has been identified as one of the central characteristics of the behavior of pathological gamblers [American Psychiatric Association (1994). Diagnostic and statistical manual of mental disorders (4th ed., DSM IV). Washington, DC: APA]. It consists of more frequent involvement, increased persistence and elevated monetary risk in an effort to recoup money that has been lost. The present research makes a distinction between within- and between-session chasing, and attempts to examine the determinants of within-session chasing in a reasonably valid laboratory analogue. Male college students who gambled (N=248) were given US$10 and an opportunity to gamble. They could: (1) decline to gamble and keep their US$10 (nonplayers); (2) gamble and win even more money by quitting at a more optimal time (nonchasers); or (3) gamble longer than they should, resulting in the loss of all available money (chasers). Zuckerman's impulsivity factor (from the ZKPQ) discriminated chasers from nonchasers. Breen and Zuckerman's Gambling Beliefs and Attitudes Survey (GABS) discriminated players from nonplayers. A sensation-seeking explanation of within-session chasing was not supported. The results are discussed in terms of the impact of impulsivity on within-session chasing. It is suggested that the GABS may serve as a general measure of ‘affinity' to gambling, and could be useful in examining the process of between-session chasing, that is, returning on another day to ‘get even'.  相似文献

A 21-item survey, regarding school psychologist role functions, was completed by 418 Ohio school superintendents. The data indicated support for traditional child study services, inservice work with teachers, and counseling or parents and children.More limited support was found for school psychologists' participation on curricula committees, general services to secondary students or preschool children, and special functions as drug consultants, researchers, and developers of legislation.The priority level assigned by superintendents to particular tasks seemed contingent upon whether there was clear reference to children referred for evaluation or to the prevention of children's problems.Despite some variations, the data was generally consistent with responses of teachers and school psychologists previously reported.  相似文献

Compared to controls, children who were diagnosed as victims of Nonaccidental Trauma or Failure to Thrive had depressed Bayley Scale Mental Index scores, p < .002and p < .0001, respecitvely. Failure-to-Thrive children also had depressed Bayley Scale Motor Index scores, p < .0001. Nonaccidental-Trauma children had Mental and Motor Scale range scores, as determined by differences between basal and ceiling items on the Mental and Motor scales, that were a function of measured Mental and Motor Index Scores. Specifically, Nonaccidental-Trauma children with lower Mental Index scores had higher Mental Scale range scores than Nonaccidental-Trauma children with higher Mental Index scores, p < .003. Control children had Mental Scale range scores that did not differ between the high-low Mental Index score conditions. On the Motor Scale, range scores of Nonaccidental-Trauma children in the highlow Motor Index score conditions did not differ. However, children with higher Motor Index scores had higher Motor Scale range scores than control children with lower Motor Index scores, p < .02. In addition, the Infant Behavior Record of the Bayley Scales revealed behavior ratings of Nonaccidental-Trauma and Failure-to-Thrive children that differed from Mental and Motor Scale scores on several dimensions. These differences may reflect differential effects of the Nonaccidental-Trauma and Failureto-Thrive conditions.This study was supported in part by Department of Health, Education and Welfare, Office of Child Development Grant OCD-CB-371.
