MATERNAL ATTITUDES ABOUT FAMILY LIFE AND CHILD REARING AS AVOWED BY MOTHERS AND PERCEIVED BY THEIR UNDERACHIEVING AND HIGH-ACHIEVING SONS.

BRIGHT TEEN-AGE BOYS ENROLLED IN SPECIAL EDUCATION PROGRAMS FOR ACADEMIC UNDERACHIEVERS AND HIGH ACHIEVERS WERE ADMINISTERED THE PARENTAL ATTITUDE RESEARCH INSTRUMENT (PARI) WITH INSTRUCTIONS TO COMPLETE THE INVENTORY THE WAY THEIR MOTHERS WOULD RESPOND. THE PARI WAS ALSO ADMINISTERED TO THE MOTHERS. THE 2 GROUPS OF BOYS DID NOT DIFFER IN PERCEPTIONS OF MATERNAL HOSTILITY, BUT THE UNDERACHIEVERS PERCEIVED THEIR MOTHERS AS SIGNIFICANTLY HIGHER ON MATERNAL CONTROL. THERE WERE NO SIGNIFICANT DIFFERENCES BETWEEN MATERNAL ATTITUDES AVOWED BY THE 2 GROUPS OF MOTHERS, ALTHOUGH THERE WAS A TREND SUGGESTIVE OF MORE CONTROL AVOWED BY MOTHERS OF THE HIGH-ACHIEVING BOYS. MUCH GREATER DIFFERENCES BETWEEN MOTHERS' AVOWAL AND SONS' PERCEPTIONS WERE FOUND IN THE UNDERACHIEVING GROUP, WITH THE MOST PRONOUNCED DISCREPANCIES BEING EVIDENCED ON MEASURES OF MATERNAL CONTROL. WHEREAS MOTHERS' AND SONS' SCORES CORRELATED SIGNIFICANTLY FOR THE CONTROL FACTOR IN THE GROUP OF HIGH ACHIEVERS, THERE WERE NO SIGNIFICANT ASSOCIATIONS BETWEEN ATTITUDES ASCRIBED TO THEIR MOTHERS AND ACTUAL ATTITUDES AVOWED BY MOTHERS OF THE UNDERACHIEVERS.

SHORT-FORM TESTS: A METHODOLOGICAL REVIEW.

REVIEWS STUDIES IN WHICH CLINICAL INTELLIGENCE TESTS ARE ABBREVIATED TO SAVE TESTING TIME. SERIOUS METHODOLOGICAL PROBLEMS ARE EVIDENT: SAMPLES ARE OFTEN SMALL, UNREPRESENTATIVE, AND HETEROGENEOUS IN COMPOSITION; AND SHORT-FORM VALIDITY IS SYSTEMATICALLY OVERESTIMATED. IT IS ARGUED THAT PRESENT STATEMENTS OF THE PROBLEM DO NOT LEAD TO A UNIQUE SOLUTION. THE GENERAL REQUIREMENT THAT AN ABBREVIATED TEST SHOULD SAVE TIME WHILE RETAINING MAXIMUM VALIDITY CANNOT BE SATISFIED IN THE ABSENCE OF A STATEMENT ABOUT THE RELATIVE UTILITY OF "TIME SAVED" AND "VALIDITY LOST."

THE EFFECT OF PRIOR EXPOSURE TO SHOCK ON A VISUAL DISCRIMINATION BY RATS.

EXAMINED THE EFFECT OF 3 DURATIONS OF PRIOR ELECTROSHOCK ON LEVER PRESSING BY HUNGRY RATS DURING THE PERFORMANCE OF A VISUAL DISCRIMINATION. TESTING OCCURRED AFTER VARYING DEGREES OF EXPERIENCE WITH EXTINCTION. ALSO STUDIED WERE THE EFFECTS OF INCREASED DRIVE ON LEVER-PRESSING BEHAVIOR AFTER PROLONGED EXTINCTION. THE RESULTS SHOWED THAT INCREASING DURATIONS OF SHOCK LED TO INCREASING SUPPRESSIONS OF OVERALL RESPONDING, ALTHOUGH THE VISUAL DISCRIMINATION ITSELF WAS NOT SO SERIOUSLY AFFECTED. THE GREATER THE EXPERIENCE WITH EXTINCTION, THE GREATER WERE THE EFFECTS OF THE SHOCK ON THE TOTAL NUMBER OF RESPONSES MADE AND THE LESS THE EFFECTS ON THE VISUAL DISCRIMINATION. INCREASED HUNGER DRIVE ENHANCED TOTAL RESPONDING WHILE IMPAIRING DISCRIMINATION. (FRENCH SUMMARY) (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

BEHAVIOR PROBLEMS OF CHILDREN AS VIEWED BY TEACHERS AND THE CHILDREN THEMSELVES.

THE 50 BEHAVIORS ORIGINALLY USED BY WICKMAN ON ADULTS WERE RATED ON A 4-POINT SCALE OF SERIOUSNESS BY 455 BOYS AND 456 GIRLS IN GRADES 7-12. BY SEX AND GRADE LEVEL, THE FREQUENCIES IN EACH CELL WERE COMPARED BY CHI-SQUARE TESTS OF INDEPENDENCE TO FREQUENCIES SIMILARLY GENERATED BY THEIR TEACHERS. CONSIDERING THE 20 BEHAVIORS RATED MOST AND LEAST SERIOUS BY THE STUDENTS, DISAGREEMENT WAS OBSERVED BETWEEN BOYS AND GIRLS, AMONG GRADES, AND BETWEEN STUDENTS AND TEACHERS. SOME OF THE BEHAVIORS GAVE RISE TO MORE DISAGREEMENTS THAN OTHERS. THE RELATIVE ORDERS OF THE BEHAVIORS AS RANKED BY STUDENTS AND TEACHERS WERE COMPARED TO THE ORDER ESTABLISHED BY WICKMAN'S ORIGINAL TEACHER GROUP.

HUNGER IN MAN: COMPARATIVE AND PHYSIOLOGICAL STUDIES.

HUNGER AND FEEDING ARE UNDER MULTIFACTOR CONTROL. THESE FACTORS ARE INTEGRATED IN THE CNS, PARTICULARLY IN THE HYPOTHALAMUS, WHERE THERE ARE BOTH EXCITATORY AND INHIBITORY MECHANISMS CONTROLLING FOOD INTAKE AND HUNGER MOTIVATION. 30 FIGURES SUMMARIZE CONCEPTIONS AND RESEARCH CONCERNING FEEDING AND DRINKING PRIMARILY IN ANIMALS. IT IS CONCLUDED THAT: "1. WE CAN STUDY FEEDING BEHAVIOR IN MAN OBJECTIVELY. 2. IN OUR EXPERIMENTAL SITUATION, WE CAN REDUCE HUMAN FEEDING TO A BASIC, PHYSIOLOGICAL, REGULATORY RESPONSE. 3. MAN IS A SUPERB PHYSIOLOGICAL PREPARATION, AND UNDER THE RIGHT CONDITIONS PERMITS THE USE OF EXPERIMENTAL MANIPULATIONS. 4. THE STUDY OF MAN ALSO GIVES US ACESS TO THE WHOLE SUBJECTIVE SIDE OF HUNGER, WITH VALIDATION IN ACTUAL FOOD INTAKE. 5. FINALLY, HUNGER AND THIRST ARE UNDER THE CONTROL OF A NUMBER OF PHYSIOLOGICAL FACTORS, CONTRIBUTING TO A CENTRAL NEURAL INTEGRATING MECHANISM THAT YIELDS THE PHYSIOLOGICAL REGULATION, THE MOTIVATIONAL CONTROL, AND PERHAPS ALSO THE SUBJECTIVE EXPERIENCE."

MILITARY PSYCHOLOGY: A COMPARATIVE IMAGE.

SALARIES AND CAREER BENEFITS OF UNIFORMED, FEDERAL CIVIL SERVICE AND NONFEDERAL CIVILIAN PSYCHOLOGISTS ARE PRESENTED AND COMPARED. JOB SATISFACTION ATTITUDES FOR THESE SAME 3 GROUPS OF PSYCHOLOGISTS ARE ALSO DISCUSSED. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

CHARACTERISTIC PACE AS DETERMINED BY THE USE OF A TRACKING TREADMILL.

IT WAS FOUND THAT WHEN SS WALKED ON A TRACKING TREADMILL UNDER A "COMFORTABLE-BUT-DETERMINED" (C-D) WALKING INSTRUCTIONAL SET FOR A MINIMUM OF 30 MIN. ON EACH OF 3 TESTING DAYS: (1) SS DEMONSTRATED A CHARACTERISTIC C-D PACE THAT WAS STABLE ON ANY GIVEN DAY, (2) SS' C-D PACES DIFFERED STATISTICALLY FROM EACH OTHER (P     

BEHAVIOR THERAPY WITH CHILDREN: A REVIEW AND EVALUATION OF RESEARCH METHODOLOGY.

PAPERS ARE CLASSIFIED IN TERMS OF THE THERAPIST'S GOALS IN TREATMENT INCLUDING: (1) DECELERATION OF MALADAPTIVE BEHAVIOR, (2) ACCELERATION OF PROSOCIAL BEHAVIOR, AND (3) COMBINED PROMOTION OF ADAPTIVE BEHAVIOR AND CONTROL OF PROBLEMATIC BEHAVIOR. ALTHOUGH A NUMBER OF THE STUDIES REVIEWED CONVINCINGLY DEMONSTRATE THE EFFICACY OF BEHAVIORISTIC TREATMENT APPROACHES, THE MAJORITY WERE INADEQUATELY CONTROLLED AND INCOMPLETELY RECORDED CASE STUDIES. IT IS SUGGESTED THAT WHEN INDIVIDUAL SS ARE USED FOR THERAPY-EVALUATION STUDIES, E SHOULD PROVIDE: (1) ADEQUATE BASE-LINE MEASURES OF THE TARGET BEHAVIOR, (2) SYSTEMATIC VARIATION OF REINFORCEMENT CONTINGENCIES OR OTHER PROCEDURES DEMONSTRATING CONTROL OF S'S BEHAVIOR, (3) EVIDENCE THAT BEHAVIOR OBSERVATIONS ARE UNBIASED, AND (4) RIGOROUS FOLLOW-UP EVALUATIONS.

PERFORMANCE AND SATISFACTION AS A FUNCTION OF INDIVIDUAL-ENVIRONMENT FIT.

RESEARCH IS REVIEWED WHICH TREATS PERFORMANCE AND SATISFACTION AS A FUNCTION OF THE INTERACTION BETWEEN THE CHARACTERISTICS OF THE INDIVIDUAL AND THOSE OF THE INTERPERSONAL AND NONINTERPERSONAL ENVIRONMENTS. RELEVANT THEORETICAL POSITIONS ARE CONSIDERED. ALTERNATIVE MODELS FOR THE ANALYSIS OF INTERACTIONS OR TRANSACTIONS BETWEEN INDIVIDUALS AND ENVIRONMENTS ARE DISCUSSED. THE CONCLUSION POINTS TO 3 QUESTIONS: SHOULD ONE CONSIDER THE PERCEIVED OR ACTUAL ENVIRONMENT? WHAT UNITS SHOULD BE USED AND SHOULD THESE BE THE SAME UNITS OF ANALYSIS FOR INDIVIDUALS AND ENVIRONMENTS? WHAT IS THE NATURE OF THE PROCESSES INVOLVED IN INDIVIDUAL ENVIRONMENT RELATIONSHIPS? (3 P. REF.) (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

DISCRIMINATION REACTION TIME AS A FUNCTION OF ANXIETY AND INTELLIGENCE.

"1. Two groups of Ss of high and low anxiety as determined by a Scale of Manifest Anxiety were given a complex discrimination-reaction-time task involving a high degree of interference. 2. While the low-anxiety group was superior in performance on the reaction-time task, it was found that this superiority could be attributed to intellectual differences rather than to differences in level of anxiety."

MEDIATION EFFECTS AS A FUNCTION OF MEDIATOR RECALL AND MEANINGFULNESS.

STUDIED MEDIATION EFFECTS AS A FUNCTION OF MEDIATOR RECALL AND MEANINGFULNESS. USING THE A-B, A-C, B-C (A-B, D-C, B-C CONTROL) PARADIGM, B AND C ITEMS WERE PRESENTED AT A 0/6, 2/6, 4/6, OR 6/6 CRITERION OF STAGE 3 ACQUISITION, AND S RECALLED THE ITEMS ASSOCIATED WITH B AND C IN STAGES 1 AND 2. THE A AND D ITEMS WERE PRESENTED AFTER STAGE 2 IN ORDER TO ASSESS DIFFERENCES IN FORWARD AND BACKWARD RECALL AT THE 0/6 CRITERION. HIGH- AND LOW-M VERBAL MATERIAL CONDITIONS WERE ORTHOGONAL TO THE RECALL CONDITIONS. THE MAJOR RESULTS WERE: (1) HIGH-M MATERIALS APPARENTLY YIELD SUPERIOR BACKWARD LEARNING AND LESS BACKWARD UNLEARNING IN STAGES 1 AND 2, THUS MAKING THE MEDIATOR MORE AVAILABLE FOR HIGH-M MATERIAL AT THE ONSET OF STAGE 3; (2) STAGE 3 ACQUISITION PRODUCES A GENERAL DECREASE IN MEDIATOR RECALL; AND (3) THERE WAS A GENERAL LACK OF RELATIONSHIP BETWEEN MEDIATOR RECALL IN STAGE 3 AND B-C PERFORMANCE. THE FINDINGS WERE INTERPRETED IN TERMS OF THE RELATION OF ASSOCIATIVE STRENGTH OF B-A AND C-A AFTER STAGE 1 AND 2 ACQUISITION AND ITS RELATION TO MEDIATOR USAGE. (FRENCH SUMMARY) (19 REF.)

RELIABILITY AND VALIDITY OF INTERNAL-EXTERNAL CONTROL AS A PERSONALITY DIMENSION.

EXTENSIVE NEW DATA ARE REPORTED ON THE TEST-RETEST RELIABILITIES AND PERSONALITY SCALE CORRELATES OF THE INTERNAL-EXTERNAL (I-E) CONTROL DIMENSION. I-E IS FOUND TO RELATE CONSISTENTLY TO MEASURES OF MALADJUSTMENT, WITH INTERNAL SCORERS LESS MALADJUSTED. I-E IS RELATED TO A VARIETY OF PERSONALITY SCALES, WITH INTERNAL SCORERS DESCRIBING THEMSELVES AS MORE ACTIVE, STRIVING, ACHIEVING, POWERFUL, INDEPENDENT, AND EFFECTIVE. FOR 2 OF 3 SAMPLES, INTERNAL SCORERS WERE ALSO SIGNIFICANTLY MORE EFFECTIVE AS MENTAL HOSPITAL VOLUNTEERS THAN EXTERNAL SCORERS. THESE RESULTS ARE CONSISTENT WITH THOSE REPORTED IN PREVIOUS REVIEWS, BUT ADJECTIVAL DESCRIPTIONS OF EXTREME SCORERS, AND OTHER DATA, SUGGEST THAT INTERNAL SCORERS ARE A MORE HOMOGENEOUS GROUP THAN EXTERNAL SCORERS. SUGGESTIONS ARE OFFERED FOR DIFFERENTIATION OF THE CONCEPT OF EXTERNALITY. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

PERCEPTION OF AND REACTION TO AMBIGUITY BY REPRESSORS AND SENSITIZERS: A CONSTRUCT-VALIDITY STUDY.

EXAMINED (1) WHETHER BYRNE'S (SEE 37:2) CONCEPTUALIZATION OF THE REPRESSION-SENSITIZATION (R-S) SCALE AS A MEASURE OF THE REPRESSION-SENSITIZATION CONSTRUCT COULD BE VALIDATED WITH EXPERIMENTALLY DEFINED MEASURES, PERCEPTUAL RATINGS OF AMBIGUITY AND RESPONSE LATENCIES, AND (2) WHETHER DIFFERENTIAL EGO INVOLVEMENT WOULD AUGMENT THE DEFENSIVE MODES OF REPRESSORS AND SENSITIZERS. STRUCTURED VERBAL AND UNSTRUCTURED PERCEPTUAL STIMULUS DIMENSIONS WERE USED, AND WITHIN EACH, 2 LEVELS OF EGO INVOLVEMENT WERE ATTEMPTED BY VARYING STIMULUS MATERIALS AND INSTRUCTIONAL SET. THE EGO INVOLVEMENT HYPOTHESIS WAS NOT SUPPORTED, BUT SENSITIZERS PRODUCED MUCH LONGER RESPONSE LATENCIES THAN EITHER REPRESSORS OR NEUTRALS. THE IMPLICATIONS OF THIS FINDING FOR A THEORY OF PERCEPTUAL TOLERANCE OF AMBIGUITY AND THE VALIDITY OF THE R-S SCALE ARE DISCUSSED. (23 REF.)

THE HUMAN USE OF PERSONALITY TESTS: A DISSENTING VIEW.

CONSIDERS PUBLIC RESENTMENT OF PERSONALITY TESTS AND PSYCHOLOGISTS' REACTIONS TO THIS. THIS ISSUE IS DESCRIBED AS "ONE OF RECONCILING 3 DIVERGENT INTERESTS: (A) THE PUBLIC'S RIGHT TO PRIVACY; (B) THE SOCIAL SCIENTIST'S FREEDOM OF INQUIRY; AND (C) THE PERSONNEL WORKER'S RIGHT TO DETERMINE FITNESS FOR EMPLOYMENT." (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

TEAM PERFORMANCE AS A FUNCTION OF TEAM ARRANGEMENT AND WORK LOAD.

32 PAIRS OF MALE UNDERGRADUATES SERVED AS RADAR CONTROLLERS IN A SIMULATED APPROACH CONTROL TASK, AND WERE REQUIRED TO ALTERNATE IN DIRECTING AIRCRAFT APPROACHES. PRESCRIBED APPROACH RATE WAS 1/MIN (HIGH WORK LOAD) OR EVERY 2 MIN. (LOW WORK LOAD). S COULD COMPENSATE FOR HIS PARTNER'S EARLY OR LATE APPROACHES IN COMPENSATORY BUT NOT IN NONCOMPENSATORY TEAMS. EACH TEAM COMPLETED 4 SESSIONS. STANDARDIZED ALGEBRAIC AVERAGE OF APPROACH TIMES WAS CLOSER TO CRITERION IN COMPENSATORY TEAMS, PARTICULARLY UNDER LOW LOAD. UNDER HIGH LOAD FEWER FLIGHT ERRORS OCCURRED IN COMPENSATORY TEAMS. TEAM COMMUNICATION INHIBITED PERFORMANCE ONLY IN THE NONCOMPENSATORY HIGH LOAD CONDITIONS. IT IS CONCLUDED THAT SOME TEAM FUNCTIONS HINDER, OTHERS ENHANCE, TEAM OUTPUT. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

THERAPIST RESPONSES TO HOSTILITY AND DEPENDENCY AS A FUNCTION OF TRAINING.

THERAPIST RESPONSES TO A TYPICAL CLIENT, A HOSTILE CLIENT, AND A DEPENDENT CLIENT WERE STUDIED AS A FUNCTION OF THE SS' TRAINING. SS WERE 18 ADVANCED GRADUATE STUDENTS IN A COURSE IN THEORIES AND TECHNIQUES OF PSYCHOLOGICAL COUNSELING. THE COURSE INCLUDED DIDACTIC MATERIAL WITH SUPERVISED EXPERIENCE IN THE FORM OF ROLE PLAYING, STRUCTURED INTERVIEWS, AND PRACTICE COUNSELING. RESPONSES TO TAPE RECORDINGS OF THESE CLIENTS WERE OBTAINED BEFORE AND AFTER THE COURSE AND WERE SCORED FOR DIRECTIVENESS. RESULTS SHOWED SS TO BE INCREASINGLY DIRECTIVE TO THE TYPICAL, HOSTILE, AND DEPENDENT CLIENTS, RESPECTIVELY, ON BOTH ADMINISTRATIONS AND SHOWED SS TO BE LESS DIRECTIVE TO ALL 3 CLIENTS ON THE 2ND ADMINISTRATION. THE DECREASE IN DIRECTIVENESS TO THE DEPENDENT CLIENT, HOWEVER, WAS NOT SIGNIFICANT. IMPLICATIONS SUGGESTED WERE THAT DIFFERENT CLIENTS ELICIT DIFFERENT RESPONSES FROM THE SAME THERAPIST, AND THAT TRAINING MAY AFFECT RESPONSES TO HOSTILITY MORE THAN IT AFFECTS RESPONSES TO DEPENDENCY.

INTEGRATIVE BEHAVIOR IN ADOLESCENT BOYS AS A FUNCTION OF DELINQUENCY AND RACE.

EXPLORES INTEGRATIVE BEHAVIOR (I.E., BEHAVIOR MAXIMIZING REWARD OVER TIME) IN 88 ADOLESCENT BOYS ALL EVINCING, VIA INTELLIGENCE TEST PERFORMANCES, COMPARABLE SYMBOLIZING CAPACITY. THE FINDINGS WERE THAT DELINQUENCY IS RELATED TO INTEGRATIVE FAILURE AS MEASURED BY CHOICE OF A SMALL BUT IMMEDIATE REWARD OVER A LARGE BUT REMOTE REWARD (CANDY). HOWEVER, CONTRARY TO EXPECTANCY, NEGRO BOYS BEHAVED MORE INTEGRATIVELY THAN WHITE BOYS. THE FINDINGS ARE DISCUSSED IN CONNECTION WITH RESULTS FOUND ON AUXILIARY MEASURES MADE ON ALL SS.

COUNTERTRANSFERENCE RESPONSE AS A FUNCTION OF THERAPIST ANXIETY AND CONTENT OF PATIENT TALK.

12 HIGH-ANXIOUS AND 12 LOW-ANXIOUS THERAPISTS LISTENED TO 3 PATIENT TAPE RECORDINGS CHARACTERIZED BY SEXUAL, AGGRESSIVE, AND NEUTRAL CONTENT, RESPECTIVELY. 10 TIMES IN EACH TAPE THE THERAPISTS WERE ASKED TO SELECT 1 OF A PAIR OF INTERPRETIVE STATEMENTS (DIFFERING IN DEGREE OF "PERSONAL INVOLVEMENT") THEY WOULD HAVE SAID HAD THEY BEEN THE THERAPIST OF THE PATIENTS. THE RESULTS CONFIRMED THE PREDICTION THAT LOW-ANXIOUS THERAPISTS WOULD BE MORE PERSONALLY INVOLVED (SHOW LESS COUNTERTRANSFERENCE) WITH THEIR PATIENTS THAN HIGH-ANXIOUS THERAPISTS. THE PREDICTION THAT BOTH GROUPS OF THERAPISTS WOULD BECOME MORE PERSONALLY INVOLVED WITH THE NEUTRAL PATIENT TAPE, IN CONTRAST TO THE SEXUAL OR AGGRESSIVE TAPES, WAS NOT SUPPORTED. (36 REF.)

RUNWAY EXTINCTION WITH AND WITHOUT SHOCK AS A FUNCTION OF ACQUISITION REWARD MAGNITUDE.

32 ALBINO RATS WERE GIVEN RUNWAY TRAINING WITH EITHER LARGE OR SMALL REWARD. WHEN RUNNING SPEEDS STABILIZED, EXTINCTION BEGAN WITH 1/2 THE SS IN EACH REWARD GROUP RECEIVING SHOCK IN THE UNBAITED GOAL BOX. AS IN PREVIOUS STUDIES, THE LARGE REWARD GROUPS EXTINGUISHED MORE RAPIDLY THAN THE SMALL REWARD GROUPS AND THE SHOCKED SS MORE RAPIDLY THAN THE NONSHOCKED. HOWEVER, NO SIGNIFICANT INTERACTION WAS FOUND BETWEEN ACQUISITION REWARD MAGNITUDE AND EXTINCTION SHOCK TREATMENT. THE RESULTS ARE INTERPRETED IN TERMS OF THE HYPOTHESIZED MEDIATING EMOTIONAL RESPONSE PRODUCED BY BOTH NONREWARD AND SHOCK.
