A psychometric examination of the multidimensional perfectionism scale

The Multidimensional Perfectionism Scale (MPS), developed by Frost, Marten, Lahart, and Rosenblate (1990), was constructed using an all female sample at an elite university. This study examined the psychometric properties of the instrument using a more typical sample (n=278) of college students from a large state university and a small liberal arts college, both located in the South. Significant differences were found on the overall MPS score as well as six of the seven subscales between this sample and that of Frostet al. No gender differences were found for any of the MPS scores. Internal reliability was found to be .88 for the total score, with subtests ranging from .57 to .95. Interscore correlations were relatively consistent with the Frostet al. sample except for a negative correlation between the PS subscale and the total score. There was a strong confirmation of the underlying factor structure reported by Frostet al. The overall impression was that the MPS is a psychometrically sound instrument of potential value in studying the construct of perfectionism.     

Reaction time measures of feature saliency in schematic faces

Two separate paradigms utilizing measurements of reaction time were employed to study facial feature saliency in schematic line drawn faces. In the first paradigm the speed of response to the omission of different facial components was measured, and in the second, the speed of response to feature substitution was measured. In both paradigms the facial features were presented in a random temporal sequence in order to minimise preferential scanning strategies. The two separate paradigms reflected the feature hierarchy most commonly found in the literature, ie the outline and eyes are more salient than the nose and mouth in terms of both speed of processing and error rate. In a third study the feature substitution paradigm was used to investigate the effects of feature saliency on the perception of emotional faces. The results suggest a change in the eyes/mouth hierarchy so that the mouth becomes the most salient feature in the surprised, happy, and sad target faces. This reverse in hierarchy, however, was not evident with the angry target face. These results are discussed in terms of changes in the focus of 'attention' and/or changes in 'processing efficiency'.     

OPERANT TREATMENT OF OROFACIAL DYSFUNCTION IN NEUROMUSCULAR DISORDERS

The popularity and reported success of biofeedback treatment for neuromuscular disorders has occurred despite a lack of research identifying the critical variables responsible for therapeutic gain. In this study, we assessed the degree to which severe neurological dysfunction could be improved by using one of the components present in all biofeedback treatment, contingency management. Three cases of orofacial dysfunction were treated by reinforcing specific improvements reliably detectable without the use of biofeedback equipment. The results showed that contingency management procedures alone were sufficient to improve overt motor responses but, unlike biofeedback treatment, did not produce decreases in the hypertonic muscle groups associated with the trained motor behavior. The findings suggest that sophisticated, expensive biofeedback equipment may not be necessary in treating some neuromuscular disorders and that important clinical gains may be achieved by redesigning the patient's daily environment to be contingently therapeutic, rather than only accommodating the disabilities of the physically handicapped.     

External threat and the definition of deviance

Research ( Lauderdale , 1976; Schachter , 1951) suggests that an external threat to a group can lead to the rejection of deviant members of the group and alteration of group communication patterns and solidarity. This study sought to extend those findings, integrate them with concepts from Simmel 's (1917/1955) work on group conflict, and link them to key issues in the societal reaction approach to deviant behavior. We examined the effect of variation in level of threat, the relationship between deviant status and nonconformity to the central task norm, the role of high-status actors in deviance designation, the relationship between rejection and negative definition of the deviant, and the effects of rejection and negative definition on group solidarity. Hypotheses were tested in an experimental design involving three conditions (strong threat, weak threat, and no threat). The results suggest that (a) the level of threat is directly related to the extent of rejection and negative definition, (b) nonconformity to the central task norm is not systematically related to deviant status, (c) high-status actors are more involved in the rejection of the deviant, (d) sociometric rejection of the deviant is accompanied by negative definition in the strong-threat condition, and (e) the level of group solidarity is related to the extent of rejection and negative definition. Implications of these findings are discussed relative to the societal reaction approach to deviant behavior and analogous processes in other social groups.     

Tilt from ahead-inverted position produces displacement of visual subjective vertical in the opposite direction

Observers who lie supine with their heads inverted report large (up to 60°) tilt of a light line in an otherwise dark room when their heads and/or bodies are tilted. Most observers report that visual subjective vertical is tilted in the direction opposite to the head/body tilt. The results can be interpreted by employing a model developed by Mittelstaedt (1983), which suggests that visual subjective vertical is derived from a gravity vector transduced by vestibular and somesthetic receptors combined with “idiotropic vectors” that represent the orientation of the observer’s own head and body axes.

The Place of Counseling in the Preparation of Student Personnel Workers

The nature of preparation of student personnel workers is currently under discussion. Because of the variety of settings within higher education in which student personnel workers function and the specialized nature of their functions, their preparation should be different from counseling psychologists. Consideration is given to the possible conflicting nature of the student personnel worker's commitment to the institution and his commitment to individual students. The inadequacy of a philosophy of counseling based on radical individualism is discussed. An attempt is made to formulate a consistent and integrated rationale for student personnel work. The position is taken that education as a counselor, based upon an adequate philosophy of individual development within lines that will benefit the whole society, is crucial to adequate functioning as an effective student personnel worker.
