HYPOTHESIZED THAT SMOKING WOULD DECREASE SS' PERFORMANCE ON PHYSICAL FITNESS TESTS CALLING FOR STRENUOUS ACTIVITY, BUT NOT FOR TESTS CALLING FOR MILD ACTIVITY. 88 SS WERE GIVEN 5 PHYSICAL FITNESS TESTS AS PART OF THEIR WORK REQUIREMENT, AND THEN ASKED TO REPORT THE NUMBER OF PACKAGES OF CIGARETTES SMOKED PER DAY. A MULTIPLE LINEAR REGRESSION ANALYSIS OF THE RESULTS, USING AGE AS A COVARIATE AND AMOUNT OF SMOKING AS THE INDEPENDENT VARIABLE, SUPPORTED THE HYPOTHESIS. THE SMOKING CONDITIONS RESULTED IN SIGNIFICANT DIFFERENCES FOR THE MOST STRENUOUS TEST AND THE 2 MODERATELY STRENUOUS TESTS WITH PERFORMANCE SCORES DECREASING AS REPORTED SMOKING SCORES INCREASED. THE LEAST PHYSICALLY DEMANDING TESTS SHOWED NO SIGNIFICANT DIFFERENCES BETWEEN SMOKING CONDITIONS. AGE WAS AN IMPORTANT FACTOR IN ACCOUNTING FOR SS' PERFORMANCE ON ALL OF THE TESTS.

BRIEFLY CONSIDERS "SOME RELATIONS SUBSISTING AMONG CREATIVITY, PRODUCTIVITY, ACHIEVEMENT, AND EMINENCE . . . . AND PROPOSES THE USE OF A MEASURE, PROFESSIONAL AGE (PA). . . . WHICH IS DEFINED AS THE NUMBER OF YEARS SINCE RECEIVING THE DOCTORAL DEGREE IN PSYCHOLOGY (PHD, SCD, OR EDD)." DATA ARE BASED ON THE PA OF AMERICAN PSYCHOLOGICAL ASSOCIATION (APA) MEMBERS, AND NUMBER OF CONTRIBUTIONS TO SEVERAL APA JOURNALS FOR A 2-YR PERIOD. EMINENCE WAS DETERMINED BY HONORS RECEIVED, LEADERSHIP OF PSYCHOLOGICAL ORGANIZATIONS, ETC. (15 REF.) (PsycINFO Database Record (c) 2010 APA, all rights reserved)  相似文献

20 SCHIZOPHRENICS, 20 DEPRESSIVES, AND 20 NORMALS WERE COMPARED ON MEASURES OF FUTURE TIME PERSPECTIVE (COHERENCE AND EXTENSION), TIME PERCEPTION (SHORT AND LONG INTERVALS), AND TIME ORIENTATION. SCHIZOPHRENICS AND DEPRESSIVES DIFFER FROM NORMALS IN TIME PERSPECTIVE EXTENSION AND COHERENCE. SCHIZOPHRENICS SHOW LESS COHERENCE THAN DEPRESSIVES, AND DEPRESSIVES SHOW A MORE CURTAILED FUTURE PERSPECTIVE THAN THE SCHIZOPHRENICS. BOTH GROUPS ESTIMATE TIME LESS ACCURATELY AND ARE LESS FUTURE ORIENTED THAN NORMALS. (PsycINFO Database Record (c) 2010 APA, all rights reserved)  相似文献

REVIEWS RESEARCH COMPARING THE TRAINING EFFECTIVENESS OF RESPONSE CONFIRMATION WITH RESPONSE PROMPTING UNDER 3 MAJOR HEADINGS: (1) VERBAL LEARNING, (2) PERCEPTUAL LEARNING, AND (3) SIGNAL MONITORING. WITH THE POSSIBLE EXCEPTION OF DISCRIMINATION LEARNING, RESPONSE PROMPTING IS FOUND TO BE AS EFFECTIVE AND OFTEN MORE EFFECTIVE THAN RESPONSE CONFIRMATION. THE MAIN VARIABLES WHICH APPEAR TO DISTINGUISH THE 2 PROCEDURES IN THE VERBAL AND PERCEPTUAL LEARNING AREAS ARE THE CONTIGUITY OF THE STIMULI TO BE ASSOCIATED AND THE OCCURRENCE OF OVERT INCORRECT RESPONSES. IN SIGNAL MONITORING, THE IMPORTANT FACTORS APPEAR TO BE EXPOSURE TO THE SIGNAL AND ITS TEMPORAL DISTRIBUTION. (39 REF.) (PsycINFO Database Record (c) 2010 APA, all rights reserved)  相似文献

GRADE SCHOOL SS AT 3 AGE LEVELS (M = 8, 91/2, AND 111/2) WERE GIVEN A TAT-LIKE PICTURE WITH A LIMITED NUMBER OF PROMINENT STIMULUS OBJECTS AND ASKED TO TELL STORIES WHICH EXCLUDED 1 OF THE STIMULI. RESPONSES WERE CLASSIFIED ACCORDING TO THE PROCESS USED IN SUPPRESSING THE FORBIDDEN STIMULUS. INTELLIGENCE, MEASURED BY SCORES ON FIGURE DRAWINGS, WAS UNCORRELATED WITH ABILITY TO SUPPRESS. DEVELOPMENTAL DIFFERENCES, HOWEVER, WERE APPARENT. SEVERAL OF THE YOUNGER SS WERE UNABLE TO COMPLY WITH THE TASK AT ALL, AND GENERALLY USED MORE PRIMITIVE SUPPRESSIVE METHODS THAN OLDER SS. IN ADDITION, THE NUMBER AND REFINEMENT OF SUPPRESSIVE TECHNIQUES USED BY ALL GRADE SCHOOL SS WERE MORE LIMITED THAN THOSE USED BY OLDER SS PREVIOUSLY STUDIED.

SS WERE SHOWN PAIRED PSEUDOWORDS (EITHER 0- OR 4-ORDER APPROXIMATION TO ENGLISH) FOR 100 MSEC. AND WERE THEN INSTRUCTED TO IDENTIFY LETTERS FROM 1 OF THE PSEUDOWORDS. APPROXIMATION TO ENGLISH OF THE PSEUDOWORDS REPORTED AND THOSE NOT REPORTED AFFECTED ACCURACY OF IDENTIFICATION. DELAYING THE POSTEXPOSURE INSTRUCTION CUE 400 MSEC. REDUCED PERFORMANCE EQUALLY FOR BOTH KINDS OF MATERIAL. IT APPEARED THAT S PROCESSES ALL THE MATERIAL, NOT JUST THAT REPORTED, AND THAT A LIMITED CAPACITY SYSTEM, RATHER THAN OUTPUT UNCERTAINTY (RESPONSE BIAS) IS REQUIRED TO EXPLAIN THE SUPERIOR RECOGNITION OF FAMILIAR MATERIALS.

ATTEMPTED TO CLARIFY THE RELATIONSHIP OF REPRESSION-SENSITIZATION TO ADJUSTMENT STATUS, SOCIAL DESIRABILITY, AND ACQUIESCENCE RESPONSE SET. SS WERE 83 HOSPITALIZED MALE MEDICAL/SURGICAL PATIENTS CLASSIFIED AS ADJUSTED AND 78 HOSPITALIZED MALE PSYCHIATRIC PATIENTS CLASSIFIED AS MALADJUSTED. THE DEFENSIVE STYLE OF REPRESSION OCCURRED WITH SIGNIFICANTLY HIGHER FREQUENCY IN THE ADJUSTED POPULATION, WHILE THE DEFENSIVE STYLE OF SENSITIZATION OCCURRED WITH SIGNIFICANTLY GREATER FREQUENCY IN THE MALADJUSTED POPULATION. THERE WAS A SIGNIFICANT CORRELATION BETWEEN THE REPRESSION-SENSITIZATION DIMENSION AND BOTH SOCIAL DESIRABILITY AND ACQUIESCENCE RESPONSE SET. HOWEVER, THE CORRELATIONS WERE LOW ENOUGH TO SUGGEST THAT THE REPRESSION-SENSITIZATION DIMENSION IS TAPPING SOMETHING NOT MEASURED BY THE OTHER 2 VARIABLES.

36 MALE AND 36 FEMALE HOODED RATS WERE GIVEN AN ADAPTATION TRIAL IN A 6-CHOICE-POINT MULTIPLE-T MAZE. FOR 1/2 THE SS THE MAZE WAS BLACK ON THE ADAPTATION TRIAL AND FOR THE OTHER 1/2 THE MAZE WAS WHITE. AFTER AN INTERTRIAL INTERVAL OF EITHER 15 MIN., 4 HR., OR 24 HR., THE CORRECT PATH OR THE CULS WERE CHANGED IN BRIGHTNESS LEAVING THE REMAINDER OF THE MAZE UNCHANGED. IT WAS FOUND THAT SELECTION OR AVOIDANCE OF A GIVEN ALTERNATIVE WAS INFLUENCED BY THE CHANGE BETWEEN TRIALS FOR ALL 3 INTERTRIAL INTERVALS BUT THAT THE AMOUNT OF INCREASE OR DECREASE IN THE SELECTION OF THE CHANGED ALTERNATIVE DECREASED WITH INCREASING INTERTRIAL INTERVALS. IT WAS ALSO FOUND THAT THE SS PREFERRED A CHANGE FROM WHITE TO BLACK TO A CHANGE FROM BLACK TO WHITE. IN OTHER WORDS, ADAPTATION, TIME BETWEEN ADAPTATION AND CHANGE, AND BRIGHTNESS PREFERENCES JOINTLY DETERMINED CHOICE-POINT BEHAVIOR. THE RELEVANCE TO CERTAIN THEORIES ACCOUNTING FOR RESPONSE TO CHANGE AND NOVELTY ARE DISCUSSED BRIEFLY. (FRENCH SUMMARY) (PsycINFO Database Record (c) 2010 APA, all rights reserved)  相似文献
