Presents an obituary for Ulric Neisser. Neisser changed the course of psychology. He moved a generation of psychologists in the direction of the field named by his first book, Cognitive Psychology (1967, Appleton-Century-Crofts). He then challenged that field with his later book Cognition and Reality (1976, W. H. Freeman). Finally, he explored cracks in the received wisdom within the fields of attention, memory, and intelligence through a distinguished array of edited volumes and provocative articles. Throughout his life, he made a marriage between belief in discovered truth and complete skepticism by means of a passionate, serial monogamy of ideas. He died on February 17, 2012, at age 83 of complications from Parkinson's disease. His many honors included election as a member of the National Academy of Sciences and as a fellow of the American Academy of Arts and Sciences.

Two experiments investigated whether survival processing enhances memory for location. From an adaptive perspective, remembering that food has been located in a particular area, or that potential predators are likely to be found in a given territory, should increase the chances of subsequent survival. Participants were shown pictures of food or animals located at various positions on a computer screen. The task was to rate the ease of collecting the food or capturing the animals relative to a central fixation point. Surprise retention tests revealed that people remembered the locations of the items better when the collection or capturing task was described as relevant to survival. These data extend the generality of survival processing advantages to a new domain (location memory) by means of a task that does not involve rating the relevance of words to a scenario. 相似文献

The conflict monitoring model of cognitive control posits that response conflict triggers a top-down enhancement of a task’s
representation in working memory. In the present study, we conducted a novel test of the conflict monitoring model using a
voluntary task switching paradigm. We predicted that a task’s representation would be enhanced following events associated
with high response conflict (i.e., incongruent trials and incorrect responses), leading participants to voluntarily choose
to repeat that task more often after these events than after events associated with low response conflict (i.e., congruent
trials and correct responses). In two experiments, performance following incongruent trials was consistent with the conflict
monitoring model. However, performance following incorrect trials did not fit with the model’s predictions. These findings
provide novel support for the conflict monitoring model while revealing new effects of incorrect trials that the model cannot
explain. 相似文献

The study explored the achromatic-color determinants of grouping of uniform surfaces. The stimuli were a set of separate uniform
achromatic disks on either a uniform or a bipartite achromatic background. The participants rated the salience of grouping
of these disks for different combinations of stimulus luminances. The results show that achromatic color similarity alone
could not sufficiently explain the pattern of obtained factorial curves but this factor coupled with the factor of surface
segregation could. Luminance contrast similarity per se was found to be unimportant for grouping. 相似文献

Accessory stimuli (AS) are task-irrelevant events (typically an auditory tone) that speed reaction time (RT). With two conditions (AS-present, AS-absent) it is unclear whether AS-presence causes benefits or AS-absence causes costs, possibly due to the expectancy violations. The current study added a third condition where AS were absent in blocks and not expected (pure blocks); in other blocks, AS occurred with a probability of 0.5 (mixed blocks), allowing cost-benefit analysis comparing AS-absent RTs in pure and mixed blocks. Results demonstrated RTs were slower when AS were absent, regardless of whether the absence occurred in a mixed block or a pure block, suggesting AS do provide a benefit to RT. Additionally, AS-facilitation across the RT distribution was analysed using cumulative distribution frequencies and ex-Gaussian parameter estimation. Both provided converging evidence that AS-facilitation increases towards the slower end of the RT distribution. The implications for the utility of AS paradigms are discussed. 相似文献

The study of human episodic memory is a topic that interests cognitive and mathematical psychologists as well as clinicians interested in the diagnosis and assessment of Alzheimer’s disease and related disorders (ADRD). In this paper, we use simple cognitive models for the recognition and recall tasks typically applied in clinical assessments of ADRD to study memory performance in ADRD patients. Our models make use of hierarchical Bayesian methods as a way to model individual differences in patient performance and to facilitate the modeling of performance changes that occur during multiple recall tasks. We show how the models are able to account for different aspects of patient performance, and also discuss some of the predictive capabilities of the model. We conclude with a discussion on the scope to improve on our results by discussing the link between memory theory in psychology and clinical practice. 相似文献

The survivor interaction contrasts (SIC) is a powerful measure for distinguishing among candidate models of human information processing. One class of models to which SIC analysis can apply are the coactive, or channel summation, models of human information processing. In general, parametric forms of coactive models assume that responses are made based on the first passage time across a fixed threshold of a sum of stochastic processes. Previous work has shown that the SIC for a coactive model based on the sum of Poisson processes has a distinctive down-up-down form, with an early negative region that is smaller than the later positive region. In this note, we demonstrate that a coactive process based on the sum of two Wiener processes has the same SIC form. 相似文献

This paper surveys the field of Judaism and health. The authors trace the history of discourse on health and healing within
Judaism, from the biblical and rabbinic eras to contemporary research and writing on Jewish bioethics, pastoral care, communal
services, and aging, including congregational and community programming related to health and illness and the emergence of
the Jewish healing movement. The work of the Kalsman Institute on Judaism and Health is described, focusing on efforts to
unite these various threads into a scholarly field emphasizing basic and applied research on the instrumental functions of
Jewish religious life for health and well-being. 相似文献

A new bill regulating ovum donation in Israel is set to pass its second and third readings in the Israel Parliament in the
upcoming months. The new law will expand the number of locally donated ova available, as previously Israeli women were prohibited
from donating eggs unless they were undergoing fertility treatment. Parallel to this legislative initiative, there has been
a change in rabbinical thinking over who is considered the mother in a case of surrogacy. Previously, the consensus has been
that the birth mother is to be considered the mother, but over the last few years there has been a change in thinking and
the genetic mother is now considered the mother. The purpose of this paper is to present the ethical and legal issues from
a Jewish perspective in determining maternal identity. The dilemma also demonstrates some of the difficulties in applying
Talmudic law to modern problems and the various methodologies used to overcome these issues. 相似文献

Deciding who should receive maximal technological treatment options and who should not represents an ethical, moral, psychological
and medico-legal challenge for health care providers. Especially in patients with chronic heart failure, the ethical and medico-legal
issues associated with providing maximal possible care or withholding the same are coming to the forefront. Procedures, such
as cardiac transplantation, have strict criteria for adequate candidacy. These criteria for subsequent listing are based on
clinical outcome data but also reflect the reality of organ shortage. Lack of compliance and non-adherence to lifestyle changes
represent relative contraindications to heart transplant candidacy. Mechanical circulatory support therapy using ventricular
assist devices is becoming a more prominent therapeutic option for patients with end-stage heart failure who are not candidates
for transplantation, which also requires strict criteria to enable beneficial outcome for the patient. Physicians need to
critically reflect that in many cases, the patient’s best interest might not always mean pursuing maximal technological options
available. This article reflects on the multitude of critical issues that health care providers have to face while caring
for patients with end-stage heart failure. 相似文献
