Psychometric Properties and Administration Measurement Invariance of Social Phobia Symptom Measures: Paper-Pencil vs. Internet Administrations

The psychometric properties of the online versions of assessment instruments for phobias and related symptoms were compared to those of paper-pencil versions. The examined measures were the Social Interaction Anxiety Scale (SIAS) and Social Phobia Scale (SPS). Students (n = 514) completed the instruments either in a paper-pencil in lab condition or an online at home condition. Means of the measures were largely equivalent between the two groups. Factor structures of the measures support construct validity of the two versions of the questionnaires. The coefficient alphas for the measures were reasonably high, ranging between .91 and .93 for both groups. Correlations between the measures were similar across groups. Overall, adequate psychometric properties of the online versions of the instruments were demonstrated, however, neither of the social phobia measures demonstrated measurement invariance between the two assessment modalities.     

The Sternberg Triarchic Abilities Test (STAT) as a measure of academic achievement and general intelligence

The degree to which practical, creative, and analytical abilities, measured by the Sternberg Triarchic Abilities Test (STAT) (Sternberg, 1993), significantly contribute to the prediction of academic achievement, independent of general intelligence, was investigated. Although Sternberg et al. (2000) claim that the STAT is not related to, nor a measure of, general intelligence, data obtained by Sternberg, Ferrari, Clinkenbeard, and Grigorenko (1996), found that STAT scores were significantly correlated with measures of general intelligence. In the present study, introductory psychology midterm examination grades, STAT scores, and Wonderlic Personnel Test scores (as a measure of general intelligence), were obtained from undergraduate students at the University of Western Ontario (N=150). Total STAT scores and each of the STAT subsection scores were significantly related to Wonderlic test scores, P<0.01, and the STAT subsections were significantly related to each other, P<0.01. The partial correlations between midterm grades and creative, practical, analytical, and total STAT scores, with the variance due to the Wonderlic test removed, were also found to be significant for practical and for total STAT scores, P<0.05, but nonsignificant for creative and analytical STAT scores. A factor analysis including midterm examination grades, the Wonderlic test, and each of the STAT subsections revealed a single general factor. Thus, some results supported Sternberg but others were contrary to his claims.     

Comparative Sacred Texts and Interactive Interpretation: Another Alternative to the “World Religions” Class

In this article we argue for an introductory course in the study of religion that proceeds through interactive interpretation as a responsible form of comparison. Interactive interpretation proceeds provisionally, and encourages students to formulate new questions of the materials instead of making final categories about the materials. We use examples from a typical classroom to show how we work with three pedagogical principles: (1) critical reading; (2) pluralism within religious traditions as well as between religious traditions; and (3) the use of the working hypothesis as a tool in analyzing religious texts. We also make an argument for textual reading as a form of living intellectual practice, which can work alongside of, and not in opposition to, other approaches to the study of religion, such as ethnographic or historical approaches.     

Free Love: A Hegelian Defense of Same‐Sex Marriage Rights

By revisiting Hegel's Philosophy of Right, I mount a Hegelian defense of same‐sex marriage rights. I first argue that Hegel's account of the Idea of freedom articulates both the necessity of popular shifts in the determinations of the institutions of right, as well as the duty to struggle to progressively actualize freedom through them. I then contend that Hegel, by grounding marriage in free consent, clears the path for expanding this ethical institution to include all monogamous couples. Lastly, I close by sketching the specifically Hegelian reasons we ought to actively struggle to expand the institution of marriage.     

Recognition memory with little or no remembering: Implications for a detection model

Remembering and knowing are two states of awareness that reflect autonoetic and noetic consciousness. Recent extensions of signal detection theory have attempted to fitremember andknow responses, which measure these states of awareness, to a continuum of trace strength or familiarity. The model assumes there are two response criteria, a remembering criterion, which is more strict, and a recognition criterion, which is more lenient and leads to any positive recognition response. The most important prediction of this model is that bias-free estimates of memory should be the same whether derived from overall hit and false alarm rates or fromremember hit and false alarm rates. We describe evidence that disconfirms this prediction and discuss other findings that the model cannot accommodate.     

Individual and group differences in intelligence and speed of information processing

A battery of eight different reaction time (RT) tests, measuring the speed with which individuals perform various elementary cognitive processes, and a group test of scholastic aptitude (the Armed Services Vocational Aptitude Battery, ASVAB) were given to 50 black and 56 white male vocational college students. The regression of the general factor scores of the ASVAB on the RT measures yielded a shrunken multiple correlation of 0.465. Although discriminant analyses, when applied separately to the ASVAB subtests and to the RT variables, showed highly comparable overall discrimination (over 70% correct classification) between the black and white groups, factor scores derived from the general factor (labeled ‘speed of information processing’) of the RT battery show only about one-third as large a mean black-white difference as the mean group difference on the general factor scores derived from the ASVAB. Comparisons were also made between the 106 vocational college students and 100 university students of higher average academic aptitude who had previously been tested on the same RT battery (Vernon, 1983a). These groups showed marked differences on the RT variables, the largest differences occuring on the tests that required more complex cognitive processing. The more complex RT tests also correlate most highly with the psychometric measures of ability within each group. The results are consistent with the hypothesis that individual differences and the mean differences between groups in psychometric abilities and scholastic achievement are related to differences in the speed of information processing as measured in elementary cognitive tasks.     

INTELLIGENCE,COGNITIVE STYLES,AND BRAIN LATERALIZATION

The concept of intelligence as a kind of mental power is criticized, since it is essentially static. Many authors wish to substitute the concept of processes or styles of thinking and learning, which might be developed by appropriate training. But there is no consensus as to which styles are of major importance in intellectual growth, and few of those suggested can be assessed objectively. They resemble the historical notion of types; and like types, they may be weak in internal consistency and generalizability. Some types which are defined by psychometric variables or factors are more promising. Currently the contrast between left brain and right brain functions is over-popularized. But it is associated both with verbal vs visuospatial abilities, and with analytic-sequential vs holistic processing. The right brain has been credited with a wide range of other functions for which there is little evidence, e.g., intuition, creativity, meditational trance states, etc. Findings from studies of brain-damaged or commissurotomized patients, and experiments with normal subjects, are outlined. The dichotomy is not the same as Das' simultaneous vs successive, Freud's primary vs secondary processes, Witkin's field independence, or Guilford's convergent vs divergent. Certain implications for education, for mental testing, and for cross-cultural research are discussed.     

Intelligence, reaction times, and peripheral nerve conduction velocity

Two studies (with sample sizes of 85 and 88) are reported that investigated relationships among measures of intelligence, speed of information processing, and peripheral nerve conduction velocity (NCV). In both studies, NCV was significantly correlated with IQ scores (rs = .42 and .48) and with reaction times (RTs; rs = −.28 and −.18): Thus, faster NCV was associated with higher IQ scores and faster speed of processing. In both studies, NCV and RTs contributed significantly, in combination, to the prediction of fullscale IQ (shrunken multiple Rs = .53 and .57), but the expected pattern of causal relationships between the variables was not borne out. The results are interpreted in terms of a “neural efficiency” model of intelligence, which has recieved support from other studies of physiological correlates of human intelligence.
