APPLICABILITY OF THE COCHRAN Q TEST AND THE F TEST FOR STATISTICAL ANALYSIS OF DICHOTOMOUS DATA FOR DEPENDANT SAMPLES.

DISCUSSES STATISTICAL ANALYSIS OF EXPERIMENTS GIVING DICHOTOMOUS DATA AND USING A DESIGN WITH REPEATED OBSERVATION OF THE SAME SS OR WITH MATCHED GROUPS. A MINOR EXTENSION OF COCHRAN'S Q TEST IS PRESENTED AND THE IMPORTANCE OF EXACTLY SPECIFYING THE NULL HYPOTHESIS WHEN USING THIS TEST IS EMPHASIZED. THE POSSIBILITY OF USING THE F TEST FOR DICHOTOMOUS DATA IS INVESTIGATED IN COMPUTER SIMULATED EXPERIMENTS. RESULTS INDICATE THAT FOR THE EXAMPLES CHOSEN, THE F TEST AS A RULE GIVES RESULTS AS GOOD AS THE Q TEST WITH REGARD TO TYPE I ERROR. APPROXIMATION TO THE THEORETICAL SIGNIFICANCE LEVEL IS GOOD EXCEPT IN SOME CASES WHERE THERE ARE VERY STRONG DEVIATIONS FROM F TEST ASSUMPTIONS.

FAILURE OF THE CONCEPTUAL STYLES TEST TO DISCRIMINATE NORMAL AND HIGHLY IMPULSIVE CHILDREN.

2 COGNITIVE DISPOSITIONS, INFERENTIAL AND ANALYTIC, AND THEIR RELATIONSHIP TO IMPULSIVE SCHOOL BEHAVIOR WERE INVESTIGATED. THE RELATIONSHIP OF THE DISPOSITIONS TO THE FISHER-CLEVELAND BARRIER SCORE WAS ALSO TESTED. THE KAGAN CONCEPTUAL STYLES TEST (CST) AND THE RORSCHACH INK BLOTS WERE ADMINISTERED TO 46 EXTREMELY IMPULSIVE BOYS IN SPECIAL 4TH-GRADE SCHOOL CLASSROOMS. THE CST WAS NOT ABLE TO DISTINGUISH THESE IMPULSIVE CHILDREN FROM KAGAN'S EQUIVALENT NORMAL SAMPLE OR FROM ANOTHER NORMAL GROUP. AS ANTICIPATED, NO SIGNIFICANT RELATIONSHIPS EXISTED BETWEEN THE BARRIER SCORE AND EITHER OF THE SCORES DERIVED FROM THE CST. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

PSYCHOLOGICAL TEST FOR PSYCHOPATHOLOGY.

DISCUSSES THE NEED FOR A STANDARDIZED PSYCHOLOGICAL METHOD OF EVALUATION OF PSYCHOPATHOLOGY COMPARABLE TO THE STANDARDIZED PSYCHOLOGICAL METHOD FOR INTELLIGENCE EVALUATION. A QUANTITATIVE APPROACH TO THE IDENTIFICATION OF MALADAPTIVE BEHAVIOR PATTERNS IS PROVIDED BY THE STRUCTURED CLINICAL INTERVIEW (SCI). THE SCI WAS DESIGNED TO SERVE AS AN INDIVIDUAL TEST OF SOCIAL AND PSYCHOLOGICAL ADJUSTMENT. IT CAN PROVIDE RELIABLE SCORES WHEN IT IS ADMINISTERED AND EVALUATED BY A SPECIALLY TRAINED CLINICAL OR COUNSELING PSYCHOLOGIST. IT MAY BE USED TO COMPARE PATIENTS WITH ONE ANOTHER, TO FOLLOW UP CHANGES IN INDIVIDUAL PATIENTS, OR TO DETECT SS WITH POTENTIAL PATHOLOGY IN THE COMMUNITY.

STUDIES IN THE SOURCES OF VARIATION IN CLOZE SCORES: I. THE RATERS.

ATTEMPTED TO FIND OUT WHETHER RATERS POSSESSING CERTAIN CHARACTERISTICS MIGHT BE BETTER AT PREDICTING SPEECH IN GENERAL, USING THE CLOZE PROCEDURE, AND ALSO WHETHER SOME RATERS MIGHT BE BETTER AT PREDICTING CERTAIN TYPES OF SPEECH (ALCOHOLIC VS. SCHIZOPHRENIC SPEECH). 279 RATERS WERE CHARACTERIZED IN TERMS OF 15 VARIABLES, INCLUDING 7 SOCIOECONOMIC CHARACTERISTICS AND 6 VERBAL PERFORMANCE MEASURES. EACH RATER WAS ASKED TO PREDICT 2 ALCOHOLIC AND 2 SCHIZOPHRENIC SPEECH PASSAGES. THE VERBAL SCORE ON THE SCHOOL AND COLLEGE ABILITY TEST RELATED SIGNIFICANTLY TO THE PREDICTION OF BOTH ALCOHOLIC AND SCHIZOPHRENIC SPEECH. THERE WAS A NEGATIVE CORRELATION BETWEEN THE VERBAL ASSOCIATION NONANTONYM POPULAR SCORE AND THE GUESSING OF SCHIZOPHRENIC SPEECH. (18 REF.)

RANGE RESTRICTION PROBLEMS IN THE USE OF SELF-SELECTED GROUPS FOR TEST VALIDATION.

DISCUSSES PROBLEMS IN CORRECTING SAMPLE STATISTICS FOR RESTRICTION OF RANGE. THE EMPHASIS IS ON CASES OF RANGE RESTRICTION RESULTING FROM SELF-SELECTION WHERE THE EXPLICIT SELECTION VARIABLE IS EITHER UNKNOWN OR UNMEASURABLE. AN EXAMPLE ILLUSTRATES THE EFFECTS OF SUBSTITUTING AN AVAILABLE IMPLICIT SELECTION VARIABLE FOR AN UNAVAILABLE EXPLICIT ONE IN THE STANDARD CORRECTION FORMULA FOR VARIOUS CORRELATIONS BETWEEN THE 2 AND FOR VARIOUS SELECTION RATIOS. THE CALCULATIONS INDICATE THAT THE SUBSTITUTION RESULTS IN AN UNDERCORRECTION IF THERE IS A SUBSTANTIAL POSITIVE CORRELATION BETWEEN THE IMPLICIT AND EXPLICIT SELECTION VARIABLES; HOWEVER, IT RESULTS IN AN OVERCORRECTION FOR SMALL OR NEGATIVE CORRELATIONS BETWEEN THE 2.

PREDICTION OF THE STANDARD MMPI SCALE SCORES FROM 71 ITEMS: THE MINI-MULT.

SELECTED 71 ITEMS AS REPRESENTATIVE OF THE CONTENT CLUSTERS TAPPED BY THE 11 STANDARD VALIDITY AND CLINICAL MMPI SCALES. THE ABILITY OF THIS ITEM POOL TO PREDICT THE STANDARD SCALE SCORES WAS CONTRASTED WITH THE ABILITY OF A RETEST TO DO THE SAME. THE ABBREVIATED FORM (THE MINI-MULT) WAS ESTIMATED TO HAVE SUFFERED ONLY A 9% LOSS IN RELIABILITY AND A 14% LOSS IN CORRESPONDENCE IN COMPARISON WITH THE READMINISTRATION OF THE STANDARD FORM. CORRELATIONAL, CODE-TYPE, AND GLOBAL RATING DATA WERE USED IN ASSESSING THE DEGREE OF CORRESPONDENCE. THE LOSS IN RELIABILITY AND CORRESPONDENCE WAS NOT SUFFICIENT TO MITIGATE AGAINST THE USE OF THE MINI-MULT WHEN A STANDARD TEST COULD NOT BE OBTAINED. METHODOLOGICAL QUESTIONS RELEVANT TO THE USE OF THE SPEARMAN-BROWN FORMULA AND FACTOR ANALYSIS ARE DISCUSSED. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

STUDIES IN THE SOURCES OF VARIATION IN CLOZE SCORES: II. THE VERBAL PASSAGES.

EXAMINED 100-WORD SPEECH SAMPLES OF 15 ALCOHOLICS AND 10 SCHIZOPHRENICS IN ORDER TO RELATE CHARACTERISTICS OF THESE SAMPLES TO THE DIFFERENTIAL PREDICTABILITY OF (1) ALCOHOLIC SPEECH UNDER DRUG VS. NONDRUG CONDITIONS (LSD-25). AND (2) SCHIZOPHRENIC AND ALCOHOLIC SPEECH, USING THE CLOZE PROCEDURE. THE DELETED WORDS IN THE SAMPLES WERE IDENTIFIED AS TO GRAMMATICAL CLASS FROM AND FREQUENCY OF USAGE, AND THESE CHARACTERISTICS WERE RELATED TO PREDICTABILITY. CHANGES IN PREDICTABILITY AS THE SPEAKER CONTINUED WERE STUDIED. THE AD HOC ANALYSIS IN TERMS OF GRAMMATICAL CLASS FORMS WAS SUGGESTIVE, BUT THE ANALYSIS IN TERMS OF FREQUENCY OF USAGE WAS NOT. PREDICTABILITY TENDED TO RISE AS THE ALCOHOLICS CONTINUED TO SPEAK, BOTH IN DRUG AND NONDRUG CONDITIONS, BUT DROPPED IN SCHIZOPHRENIC SPEECH.

SUGGESTIBILITY IN THE NORMAL WAKING STATE.

EVALUATES ATTEMPTS TO CLASSIFY AND ACCOUNT FOR SUGGESTIBILITY OBSERVED IN NORMAL SS UNDER WAKING (NONHYPNOTIC) CONDITIONS. FACTOR ANALYTIC STUDIES DO NOT CONFIRM THE TRADITIONAL CLASSIFICATION OF "PRIMARY" AND "SECONDARY" SUGGESTIBILITY PRESENTED BY EYSENCK AND FURNEAUX. THESE STUDIES IDENTIFY AT LEAST 3 TYPES OF SUGGESTIBILITY: PRIMARY (MOTOR), CHALLENGE, AND IMAGERY (SENSORY) SUGGESTIBILITY. INTRINSIC, STIMULUS, AND RESPONSE CHARACTERISTICS OF SUGGESTIBILITY TESTS ARE EXAMINED. SUGGESTIBILITY DOES NOT SEEM TO DEPEND ON SET, EXPECTANCY, OR SITUATIONAL VARIABLES; IS NOT ADEQUATELY EXPLAINED BY IDEOMOTOR ACTION; AND IS UNRELATED TO THE PLACEBO RESPONSE. STATE-SPECIFIC RESPONSE TO SUGGESTION OCCURS DURING SLEEP. SUGGESTIBILITY MAY BE RELATED TO ASPECTS OF CLASSICAL, VERBAL, AND SENSORY CONDITIONING. (72 REF.)

连铸二冷气雾冷却过程导热反问题分析

建立了连铸二冷气雾冷却一维非稳态导热过程中由铸坯内部单个测温点测得的温度值反算表面未知温度和表面热流密度的数学模型,利用热平衡法建立各节点差分方程,引入灵敏度系数,通过牛顿迭代法优化假设初始值。为了验证该数学模型的正确性,在铸坯表面施加已知热流密度,结果表明反算得到的热流密度与已知热流密度吻合较好。

AN EVALUATION OF THE TRAIL MAKING TEST.

3 GROUPS (21 SS IN EACH) OF HOSPITALIZED WHITE MALES, HOMOGENEOUS AS TO AGE, SEX, AND EDUCATION, WERE EXAMINED WITH THE TRAIL MAKING TEST (TMT). THE GROUPS WERE IDENTIFIED AS BRAIN-DAMAGED, MIXED NEUROPSYCHIATRIC, AND HOSPITALIZED CONTROLS. THE NULL HYPOTHESIS THAT THE TMT SCORES OF THE 3 GROUPS WOULD NOT DIFFER SIGNIFICANTLY COULD NOT BE REJECTED. ALTHOUGH PART A OF THE TMT DIFFERS SIGNIFICANTLY FROM PART B, THE DIFFERENTIAL PSYCHOLOGICAL ATTRIBUTES BEING TAPPED BY BOTH ARE UNKNOWN. IT IS SUGGESTED THAT IF THE TMT IS TO BE APPLIED IN A CLINICAL SETTING, CONSIDERABLY MORE INFORMATION IS NEEDED CONCERNING TEST PERFORMANCE AS A FUNCTION OF AGE.

SOCIAL INTERVENTION AND THE PROBLEM OF PSYCHOLOGICAL ANALYSIS.

DEFINING THE PRIMARY TASK OF COMMUNITY PSYCHOLOGISTS AS THAT OF INTERVENING AT THE SOCIAL SYSTEM LEVEL TO MODIFY HUMAN BEHAVIOR, SEVERAL CONCEPTUAL PROBLEMS THAT NEED CLARIFICATION AND DEVELOPMENT ARE POSED. THE IMPLICATIONS OF THE MEDICAL MODEL AND THE NEED FOR A THEORY OF MASS MOVEMENTS ARE DISCUSSED. IT IS SUGGESTED THAT THE DEVELOPMENT OF NEW CONCEPTS IN THESE AREAS MAY LEAD TO A NEW SCHOOL OF PSYCHOLOGY. (PsycINFO Database Record (c) 2010 APA, all rights reserved)
