The influence of syntactic segmentation on perceived stress

Chomsky and Halle (1968) claim that the stress and intonation of an utterance are not determined solely by physical properties of the acoustic signal but are also influenced by the syntactic organization of the utterance. Strong support for their contention has been obtained by presenting listeners with a continuously repeated string of monosyllabic words. Such sequences undergo spontaneous perceptual re-grouping sometimes producing strings with different syntactic organizations; such syntactic changes are accompanied by immediate and dramatic changes in apparent stress and intonation although the physical signal itself never varies.     

Extinction of a phobia of physical examination in a seven-year-old mentally retarded boy—A case study

Counterconditioning is a process in which aversive stimuli that ordinarily evoke emotional or avoidance responses are paired with positive stimuli which evoke incompatible activities. Several sets of operations have been employed to induce these incompatible activities (e.g. food, Jones, 1924; relaxation. Grossberg, 1964; positive imagery, Lazarus and Abramowitz, 1962; pharmacological agents, Friedman, 1966; laughter, Ventis, 1973).Although the Counterconditioning process has been successfully applied to a wide variety of emotional disorders, special problems arise when the procedure is applied to the mentally retarded. First, because of the limitations in cognitive abilities, it is generally impossible to train the subject in either relaxation or positive imagery processes. Consequently, it is necessary to place the child in direct contact with the anxiety-inducing situation. Secondly, it is often difficult to find an anxiety-free situation which is incompatible with the anxiety-arousing situation and which can be practically implemented, particularly when the phobia involved is complex.The purpose of this paper is to describe a case whereby a phobic response of physical examination by male doctors in a 7–yr-old mentally retarded boy was extinguished by pairing the examination with an anxiety-free situation, i.e. an extremely comfortable relationship between the patient and a nurse on the ward. Previous research had indicated that parents and people who have positive relationships with a person might possibly serve as effective anxiety reducers in fear-provoking situations (Jersild and Holmes, 1935).     

Data integration in legal evaluations: Can clinicians deliver on their premises?

Clinicians often claim to base their conclusions on configural analysis and integration of most or all of the data. However, research suggests that subjective beliefs about complex interpretive strategies and their resultant success are largely illusory. Studies show that: (1) access to more data does not necessarily improve judgmental accuracy, (2) clinical judgments, which purportedly depend on configural analyses, can usually be duplicated by simple linear models, (3) individuals often have difficulty deciphering interactions or patterns among just two or three variables, and (4) actuarial methods, even those that simply add variables together, almost always equal or exceed the accuracy of clinicians who purport to integrate large amounts of information. Corrective suggestions are discussed that may help the clinician better manage large data sets.     

Levels of selective attention revealed through analyses of response time distributions

The present research examines the nature of the interference effects in a number of selective attention tasks. All of these tasks result in interference in performance by presenting information that is irrelevant to task performance but competes for selection. The interference from this competing information slows the response time (RT) of participants relative to a condition where the competition is minimized. The authors use a convolution of an exponential and a Gaussian (ex-Gaussian) distribution to examine the influence of interference on the characteristics of RT distributions. Consistent with previous research, the authors show that interference in the Stroop task is reflected by both the Gaussian and exponential portions of the ex-Gaussian. In contrast, in 4 experiments they show that several other interference tasks evidence interference that is reflected only in the Gaussian portion of the ex-Gaussian distribution. The authors suggest that these differences reflect the operation of different selection mechanisms, and they examine how sequential sampling models accommodate these effects.     

Holistic thinking is not the whole story: alternative or adjunct approaches for increasing the accuracy of legal evaluations

There are a number of very helpful, but often underutilized, principles and procedures that can augment decision making in clinical and legal settings. Psychologists often restrict their range of decision-making strategies and options--at the cost of maximizing diagnostic and predictive accuracy--in part as the result of "ontological-epistemological one-worldedness" (O-E O-W). However, no philosophical, logical, or scientific necessity demands strict consistency between views regarding the nature of psychological phenomena and views about how to best assess or learn about those phenomena. Relaxing this unnecessary and largely psychologically-based O-E O-W may promote greater comfort with and utilization of the methods that are discussed in this article for increasing judgmental accuracy.
