Ulric neisser (1928-2012)

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.

Adaptive memory: enhanced location memory after survival processing

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.     

Cost–benefit and distributional analyses of accessory stimuli

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.     

Understanding memory impairment with memory models and hierarchical Bayesian analysis

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.     

An Extension of SIC Predictions to the Wiener Coactive Model

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.     

We're all in this together now: group performance feedback to increase classroom team data collection

This study's primary goal was to evaluate the use of performance feedback procedures delivered to a classroom team to increase daily data collection. Performance feedback (PFB) was delivered to four classroom teams responsible for the daily collection of data representing student performance during prescribed instructional activities. Using a multiple-baseline design, the effects of the team performance-feedback were evaluated for the target student, and for generalization to data collection for all classroom students. A secondary question evaluated if student on-task behavior correlated with increased data collection. Finally, social validity was investigated to evaluate team satisfaction with the PFB intervention. The results demonstrate improved data collection across all four classroom teams for the target student in each classroom and generalization within classrooms to all remaining students. Slight increases in student on-task behavior were observed in three of the four classrooms, and teacher satisfaction ratings were high.     

Examination of the Psychometric Properties of the Spiritual Fitness Assessment

Using a sample of 196 undergraduate students, the present study investigated the psychometric properties of the Spiritual Fitness Assessment, a measure of spiritual fitness designed for use by health and fitness professionals. Examination of inter-item consistency produced satisfactory alpha coefficients for the total test and its three subscales. Correlations of the SFA with measures of spirituality and spiritual well-being provide support for convergent validity. Significant positive correlations with a measure of self-esteem suggest that the test has satisfactory criterion validity. Correlations with age, sex, and a measure of social desirability indicate that the SFA is significantly, though only moderately, affected by demographic variables and motivated response tendencies. Factor analysis of the SFA items indicate that the test is factorially complex and subscales may need to be refined to better measure their intended constructs. Overall, the results of the study suggest that the test may be useful for evaluations of spiritual fitness. Further research with samples drawn from different populations is needed on the test to better establish its reliability and validity.     

Noise effects on human performance: a meta-analytic synthesis

Noise is a pervasive and influential source of stress. Whether through the acute effects of impulse noise or the chronic influence of prolonged exposure, the challenge of noise confronts many who must accomplish vital performance duties in its presence. Although noise has diffuse effects, which are shared in common with many other chronic forms of stress, it also exerts its own specific influences on various forms of cognitive and motor response. We present a quantitative evaluation of these influences so that their harmful effects can be mitigated, their beneficial effects exploited, and any residual effects incorporated and synthesized into selection, training, and design strategies to facilitate human performance capacities. Predictions of single and joint moderator effects were made on the basis of major theories of noise and performance, specifically those explanations based on arousal, masking, or cognitive-resource mechanisms. These predictions were tested through moderator analyses of effects as a function of task type, performance measure, noise type and schedule, and the intensity and duration of exposure. Observed outcome effects (797 effect sizes derived from 242 studies) varied as a function of each of these moderators. Collective findings identified continuous versus intermittent noise, noise type, and type of task as the major distinguishing characteristics that moderated response. Mixed evidence was obtained for the traditional arousal and masking explanations for noise effects. The overall pattern of findings was most consistent with the maximal adaptability theory, a mental-resource-based explanation of stress and performance variation.     

The use and impact of the analyst's subjectivity with empathic and other listening/experiencing perspectives

As part of the epistemological transition from positivistic to relativistic science that had begun earlier in the twentieth century, Kohut (e.g., 1959, 1977, 1982, 1984) attempted to update psychoanalytic thinking in formulating the empathic mode of observation. The purpose of this paper is to reassess, through a conceptual and historical lens, the considerable controversy generated by the empathic perspective. The author specifically addresses constructivist philosophical underpinnings, the use and impact of the analyst's subjectivity, the inclusion of unconscious processes, the need for additional listening perspectives, and the influence of theoretical models in the organization of empathically acquired data. An illustrative clinical vignette is discussed.
