The number of active sweat glands (PSI, palmar sweat index) in stress caused by blood donation

The number of active sweat glands (PSI), heart rate, systolic (SBP) and diastolic blood pressure (DBP) were assessed every 2 minutes in 109 male blood donors. Three measurements were taken at the beginning (adaptation phase), three later but before blood donation (baseline), one during the venous puncture (phase 3), three thereafter but still during donation (phase 4), and four after removal of the cannula (phase 5). Analysis of variance yielded significant differences between phases; PSI and SBP behaved similarly, decreasing from adaptation to baseline, rising during puncture, and decreasing again thereafter. Mean within-subject correlations between variables were significantly above 0. Between-subjects correlations were significantly negative for PSI and DBP. This is best explained by the influence of age on both variables. Correlations of PSI values as determined by three raters had a mean of 0.90. The study shows that the PSI is a very sensitive indicator of stress that is easily accessible also in field studies.     

A kinematic analysis of anticipatory coarticulation in the speech of anterior aphasic subjects using electromagnetic articulography

An investigation was made into the extent and time course of anticipatory coarticulation in the speech of two normal and two anterior aphasic, German-speaking subjects. Both labial and velar coarticulation gestures were investigated. Subjects produced sentences containing target words contrasting in postconsonantal vowel rounding (e.g., [geli:ge]/[gely:gel]) and in nasality (e.g., [ti:de]/[ti:ne]). Speech kinematics were monitored by means of electromagnetic articulography. The data revealed that for correct productions, aphasic speakers' coarticulatory patterns were more highly variable than those of control subjects. These differences, however, were found chiefly for spatial displacement characteristics, while the temporal aspects of articulator movement necessary for anticipatory coarticulation appeared largely intact. Articulator mistiming did not appear to explain a small corpus of stop/nasal substitution errors produced by one of the aphasic speakers.     

Visual and tactile memory for 2-D patterns: Effects of changes in size and left-right orientation

Visual identification of 3-D objects depends on representations that are invariant across changes in size and left-right orientation. We examined whether this finding reflects the unique demands of processing 3-D objects, or whether it generalizes to 2-D patterns and to the tactile modality. Our findings suggest that object representation for identification is influenced greatly by the processing demands of stimulus materials (e.g., 2-D vs. 3-D objects) and stimulus modality (touch vs. vision). Identification of 2-D patterns in vision is adversely affected by left-right orientation changes, but not size changes. Identification of the same patterns in touch is adversely affected by both changes. Together, the results suggest that the unique processing demands of stimulus materials and modality shape the representation of objects in memory.     

Religious Coping and Heart Transplantation: From Threat to Health

Previous research has established the existence of homogeneous religious coping profiles in cardiac-transplantation candidates labeled as the deferring/collaborators, self-directors, and the eclectic religious copers. However, their prospective impact on outcome has not yet been established. This paper examines potential differences between pre-cardiac transplantation religious coping cluster groups on post-cardiac transplantation quality of life (physical functioning, mental health, and general health). Results indicated that the religious coping profiles of deferring/collaborators and self-directors had significantly better scores on mental health and general health than did the eclectics. Implications for religious-coping research and clinical practice are discussed.     

Two Types of Externalism

A contrast is drawn between two types of externalism, one based on ideas of Wittgenstein, the other on arguments from Putnam. Gregory McCulloch's attempt to combine the two types is then examined and criticized. Putnamian externalism is ambiguous. It can be interpreted either as the empirical claim that we give priority to scientific as opposed to other forms of discourse, or as a metaphysical claim that our language attempts to conform to the structure of the world 'in itself'. But the first claim is simply false, and the second involves a form of metaphysical realism that a Wittgensteinian must reject as unintelligible. McCulloch's attempted synthesis of the two types is therefore either incoherent, or else simply adds an empirical falsehood to Wittgenstein's conceptual point. It is also noted that Putnam himself has progressively retreated from his original claims, and now appears to be a Wittgensteinian, but not a 'Putnamian', externalist.     

CONCEPT LEARNING AND LEARNING STRATEGIES

Abstract —Concept teaming and learning strategies of pigeons were manipulated in a matching-Co-sample task. Groups of 4 pigeons responded either 0, J, 10, or 20 times to a sample stimulus, and then chose between a matching comparison stimulus and a nonmatching comparison stimulus. Tests with unfamiliar arrangements of the three training stimuli showed that learning was not by if-then rules. Tests with novel stimuli showed that as the number of sample responses increased, learning about the configural pattern of each display gave way to more teaming about the sample-comparison relationship and more concept learning. Pigeons making the most sample responses showed complete concept teaming.     

Should the behavioral sciences become more pragmatic? The case for functional contextualism in research on human behavior

Although societal need for behavioral science research is enormous, current research practices seem to be inefficient vehicles for producing knowledge that guides practical action. Many of our most popular theories provide little direct guidance for application. They focus on the development of models of the relationships among organismic events such as attitudes, self-efficacy expectations, and behavior, but pay little or no attention to the contextual influences on behavior. Such research is in keeping with a long-standing mechanistic tradition in psychology. We propose a version of contextualism as an alternative paradigm for the behavioral sciences. According to this paradigm, theories and research are evaluated in terms of their contribution to the prediction and influence of behavior. Basic research organized to pursue this goal has a direct bearing on how behavioral phenomena can be changed for practical purposes. Conversely, applied research contributes to basic understanding of the determinants of psychological phenomena.     

Qualitative dimensions of normal worry and normal obsessions: A comparative study

Despite the crucial role typically given to negative thoughts in cognitive conceptualisations of emotional problems, few studies have compared the characteristics of varieties of such thoughts. The present study compared the process features of naturally occurring worries and obsessions in a non-patient group. Analyses of variance revealed several significant differences between these types of thought. The relationship between worries and obsessions, and the clinical and conceptual importance of the observed differences is briefly discussed.     

Gender Differences in College Students' Career Maturity and Perceived Barriers in Career Development

Gender differences in 401 college students' career maturity were investigated. Quantitative measures included career-mature attitudes, career decision-making skills, and vocational congruence. Analyses revealed that female students scored significantly higher than did male students on each of the career maturity measures (p < .005). Nearly one third of the students (n = 128) were also interviewed. Qualitative analyses of the interviews revealed that the perception of barriers may serve as a motivating force in many students' career development. Findings suggest that current theories of career development may be lacking in their application to many of today's college students. Ideas for future research on the perception of barriers to career attainment are discussed.
