The Effects of Force and Direction Uncertainty on Choice Reaction Time in an Isometric Force Production Task

The two experiments reported examined the temporal organization of force and direction motor-programming processes in a step-input tracking type task. Both experiments observed a reduction in reaction time in the direction-uncertain conditions compared to the direction-certain ones. Thus it seems as though the direction decision does not have to precede the selection of the proper amount of force. Experiment 2 observed an underadditive interaction between levels of direction uncertainty (certain or uncertain) and levels of force uncertainty (certain or uncertain). This interaction was interpreted as support for a parallel organization of the processes responsible for the programming of force and direction and thus, strongly supports the parallel model of programming recently proposed by Klapp (1977a, b).     

Symmetry, Compact Closure and Dagger Compactness for Categories of Convex Operational Models

In the categorical approach to the foundations of quantum theory, one begins with a symmetric monoidal category, the objects of which represent physical systems, and the morphisms of which represent physical processes. Usually, this category is taken to be at least compact closed, and more often, dagger compact, enforcing a certain self-duality, whereby preparation processes (roughly, states) are interconvertible with processes of registration (roughly, measurement outcomes). This is in contrast to the more concrete “operational” approach, in which the states and measurement outcomes associated with a physical system are represented in terms of what we here call a convex operational model: a certain dual pair of ordered linear spaces–generally, not isomorphic to one another. On the other hand, state spaces for which there is such an isomorphism, which we term weakly self-dual, play an important role in reconstructions of various quantum-information theoretic protocols, including teleportation and ensemble steering. In this paper, we characterize compact closure of symmetric monoidal categories of convex operational models in two ways: as a statement about the existence of teleportation protocols, and as the principle that every process allowed by that theory can be realized as an instance of a remote evaluation protocol—hence, as a form of classical probabilistic conditioning. In a large class of cases, which includes both the classical and quantum cases, the relevant compact closed categories are degenerate, in the weak sense that every object is its own dual. We characterize the dagger-compactness of such a category (with respect to the natural adjoint) in terms of the existence, for each system, of a symmetric bipartite state, the associated conditioning map of which is an isomorphism.     

The Rorschach Concept Evaluation Technique

The Back Pain Classification Scale (BPCS). identifies patients whose low back pain reflects a primary psychological disturbance. BPCS scores were related to the MMPI, State-Trait Anxiety Inventory, Multiple Affect Adjective Check List, and Social Readjustment Rating Scale scores; to distribution, intensity, and activities affecting pain; and to social characteristics of t 16 patients. High scores on the BPCS (psychological disturbance) are associated with elevated MMPI profiles, and with more widely distributed and more intense pain. Stepwise multiple regression solutions indicate that the MMPI Hypochondriasis (Hs) scale accounts for 15.5% of the variance. No other variable accounts for as much as 3% of the variance. Scores on Hs relate primarily to words in the BPCS psychologically disturbed pole, supplying convergent validity to the BPCS. BPCS scores are unrelated to social characteristics, implying usefulness with the variety of patients seen for evaluation of low back pain.     

Stability of the MCMI Among Depressed Psychiatric Outpatients

The Milton Clinical Multiaxial Inventory (MCMI) is a promising, yet somewhat unproven psychometric inventory developed to identify clinical syndromes and personality traits consonant with the Diagnostic and Statistical Manual of Mental Disorders (3rd ed. [DSM-III]; American Psychiatric Association, 1980). The stability of its measures for both the theoretically more stable personality characteristics and the clinical syndromes was investigated in a group of depressed psychiatric outpatients. In this test-retest design with a 3-month interval between tests, clinical syndrome scales of relevance changed significantly as expected. However, many of the personality scales also changed significantly. Only four of the personality scales met a two-fold test of stability. Findings are discussed in terms of characteristics of self-report inventories such as the MCMI, the uniqueness of the depressed population, and characteristics of personality disorders.     

The Clinical Inference Process and the Role of Theory

Perhaps the most challenging and creative aspect of clinical testing is the clinical inference process, the sequential steps the examiner takes in transforming the raw test data into a clinically relevant testing report. Unfortunately, this part of the testing process has received little attention in the testing literature. In this article, the specific steps in the inferential process are outlined. In addition, the ways in which theory enter into the inferential process are also discussed.     

Heroin Addicts' Views of Commonly Abused Drugs: A Semantic Differential Approach

52 heroin addicts were given a form of the Semantic Differential asking for their perceptions of heroin, methadone, LSD, amphetamines and marijuana. Marijuana was viewed most favorably, heroin least favorably. Views of heroin and marijuana were positively correlated; but not so heroin and methadone. There was a positive relationship between length of time on methadone maintenance and the potency score for heroin.     

A Comparison of Normals and Schizophrenics on a New Scale of the Rorschach CET

A new scale for scoring the number of correct responses on the Rorschach Concept Evaluation Technique was developed, based on the responses of 250 normal subjects. Using this scale the scores of 125 hospitalized schizophrenics were compared with the normals. The two groups we're differentiated at better than the .001 level.     

On the Attention — Demand Value of Rorschach Stimuli

The attention-demand value of the Rorschach stimuli was investigated by measuring free looking time elicited by each card. Reports of content were not given by Ss. There were significant differences between cards in amount of looking which they elicited. This was closely related to judged complexity of the cards (r = .78) and response productivity of the cards under normal administration of the Rorschach test (r = .72). A comparison of looking times under two instructions, non-defensive and defensive, showed that the instructional variable tended to produce greater differences in looking time for some cards than for others. Cards low in complexity showed relatively longer looking times under the defensive conditions.     

Empirical Correlates of the MMPI–2 Restructured Clinical (RC) Scales in Psychiatric Inpatients

We identified empirical correlates of the MMPI–2 Restructured Clinical (RC) scales in 1,872 male and 498 female psychiatric inpatients drawn from 2 large tertiary care medical centers. We generated clinical criteria from a systematic review of the patients' intake and discharge medical records. We report zero order correlations between RC scales and clinical criteria and relative risk ratios for dichotomous variables. We found the RC scales to be correlated with conceptually relevant criteria such that for each scale, we identified significant increases in the risk for a variety of emotional, cognitive, and behavioral problems among individuals whose T score exceed 64.     

Cohort Differences in Hand Test Performance: A Time Lagged Analysis

In order to examine the impact of cultural differences (cohort and/or time of measurement) on the intrapsychic processes of older adults, two samples (1976, n = 102; 1986, n = 88) of older persons were compared with regard to their Hand Test (HT; Bricklin, Piotrowski, & Wagner, 1962; Wagner, 1983) performance. Relative to those studies investigating cultural effects in personality at the socioadaptational level (Neugarten, 1977), no research to date has examined this issue utilizing projective methods of assessment. Time-lagged analyses of HT scores of these two samples of elderly adults suggested that there appear to be clear age-related variance in HT performance for both content and derived HT variables. Age-related within-sample variability for most HT scores supported this interpretation. These findings are in contrast to those utilizing more standardized, nomothetic measures of personality functioning that suggest stability of personality in adulthood.
