POTENTIAL EFFECTS OF BANDING AS A FUNCTION OF TEST RELIABILITY

Cascio, Outtz, Zedeck, and Goldstein (1991) described the application of a number of test score banding procedures in personnel selection. Equations are developed illustrating the relationship between the width of test score bands and test reliability. When reliability is moderate to low, bands are likely to be larger than the standard deviation of the test, and are likely to include a large proportion of the applicant pool. The relationships between band widths and the differences between higher scoring and lower scoring groups are also examined. When the band is smaller than the differences between groups (which may happen when highly reliable tests are used), banding may not by itself prove effective as a means of reducing the adverse impact of tests, even when banding systems that maximize opportunities for members of the lower scoring group are used.     

DISTINGUISHING BETWEEN EXTINCTION AND PUNISHMENT EFFECTS OF RESPONSE BLOCKING: A REPLICATION

Lerman and Iwata (1996) described a method for distinguishing between sensory extinction and punishment effects of response blocking on self-injurious behavior maintained independent of social contingencies. Results of their study suggested that blocking decreased the self-injurious hand mouthing of their participant via punishment. The current replication of these procedures with the self-injurious eye poking of a woman with developmental disabilities produced patterns of responding indicating that, for this participant, blocking functioned as an extinction procedure.     

MOTHERS' ALCOHOL CONSUMPTION DURING PREGNANCY:

Abstract— Fourteen-year-old adolescents' behavior on a spatial-visual reasoning task was associated with self-report of their mothers' alcohol consumption during pregnancy, IS years earlier The task was arranged so that it was possible to evaluate the examinees' tendency to respond rapidly and less accurately, or slowly and more accurately The greater the mother's reported drinking, the faster and less accurately the adolescent responded The decrement in visual-spatial reasoning related to alcohol appears to be linked to a tendency toward impulsive responding     

MODELING INFLUENCES ON ALCOHOLICS' RATES OF ALCOHOL CONSUMPTION

Two experiments were designed to examine modeling influences on alcoholics' alcohol consumption. Three male alcoholics were paired with confederates, posing as alcoholics. In Experiment 1, alcoholic-confederate pairs participated in a 1-hour taste-rating task, which involved rating different wines on a list of adjectives. Experiment 2 consisted of 1-hour ad lib access to wine in a naturalistic bar setting. In both experiments, confederates alternated 15-minute periods of heavy and light consumption, drinking fluids resembling wine. The amount of wine consumed by alcoholics in each period was secretly recorded and the data examined on a single subject basis. In Experiment 1, two subjects increased and decreased consumption along with their confederate. The third subject followed the confederate's pattern only after the confederate demonstrated heavy consumption. All three subjects varied consumption with the confederate during Experiment 2, performed later on the same day. These results suggest that alcoholics' alcohol consumption can be modified by the social influences of modeling. The implications of this finding for the loss of control hypothesis and alcoholism treatment maintenance were discussed.     

PREDICTIVE EFFICIENCY AS A FUNCTION OF AMOUNT OF INFORMATION

The effect of changing the amount of information on judges' predictive efficiency in a clinical prediction task was studied. Thirty judges predicted 30 students' average achievement scores on the basis of different amount of test data. One group of judges had information about the intercorrelations among the tests and the ecologkal validity of the tests. Another group of judges had only informahion about which tests were used. The predictive efficiency was not a monotonically increasing function of amount of test data. The most marked result was that the relative predictive efficiency decreased from four to six tests in both groups.     

ELECTRODERMAL RESPONSES AS A FUNCTION OF QUANTIFIED THREAT

N iemelá , P. Electrodermal responses as a function of quantified threat. Scand. J. Psychol ., 1969, 10 , 19–56.—Threat was quantified by means of a 20 sec anticipation condition where the subject knew the exact time for the expected shock in advance, as well as the exact probability of receiving a shock. The probabilities used where 0.00, 0.25, 0.50, 0.75 and 1.00. The electrodermal responses (the amplitude of the skin resistance response, the amplitude of the skin potential response, and the number of electrodermal responses) during the anticipation period were found to vary systematically as functions of the probability of shock, and as functions of the time elapsed from the beginning of the experiment.     

FACTORS OF EMOTIONALITY RELATED TO ALCOHOL CONSUMPTION IN LABORATORY MICE

Fifty mice from four genotypes were tested on a factor analyzed battery of measures of emotionality. This was followed by testing of alcohol consumption. The factors were related to alcohol consumption by a stepwise regression procedure. Among the five best predictors, Factor B, interpreted as a disorganization factor and Factor C, interpreted as an audiogenic reactivity factor, were most consistently related to alcohol consumption.     

LOUDNESS AS A FUNCTION OF THE DURATION OF AUDITORY STIMULATION

The perceived loudness of a 1000 c/s tone was measured by a direct scaling method under different conditions of intensity (19–35 db) and duration (50–500 msec) of stimulation. It was found that loudness grows as a logarithmic function of stimulus duration; the relation was verified for ten individual subjects and four levels of intensity. In addition, the relation between temporal threshold and level of intensity was tentatively described.     

PERCEIVED INTENSITY OF ODOR AS A FUNCTION OF TIME OF ADAPTATION

The perceived intensity of odor under conditions of constant stimulation with hydrogen sulphide was investigated in two experiments. A two-step scaling method, involving cross-modality matching and numerical scaling of the matching continuum, was used for measuring intensity of odor. Perceptual intensity was found to decrease exponentially with increase of time of stimulation. Preliminary data concerning the subsequent recovery phase were also obtained.

CHANGES IN LANGUAGE BEHAVIOR AS A FUNCTION OF VERACITY

In this experiment 20 subjects were placed in a situation designed to elicit a number of truthful and untruthful statements. Differences in these statements were examined by the SLCA III and LEXIC programs to find variables that discriminate between truth-tellers and liars. The results indicate that when lying, individuals use fewer words, and, as a consequence, fewer unique words with larger type-token ratios and smaller perceptual-cognitive activity measures, use fewer past tense verb forms, and that males tend to use a greater number of indicative mood sentences and fewer subjunctive mood sentences. When used in a discriminant function equation, 14 of the SLCA III and LEXIC variables were able to provide an adequate level of classification for the veracity of the subjects' statements.     

BINOCULAR RIVALRY AS A FUNCTION OF INCONGRUITY IN MEANING

This is the third of a series of three papers dealing with semantics of facial expressions. The purpose of this experiment was to determine whether the ratings of two stimulus inputs on semantic differential scales would predict the experience of binocular rivalry. The stimuli used were five full-face photographs of a man expressing different emotions. These stimuli were rated on the semantic differential and all possible pairs of these stimuli were used as stereograms. It was hypothesized that semantically incongruous stimulus inputs would lead to binocular rivalry and that congruous ones would lead to an absence of rivalry. The hypothesis was supported.     

FREE RECALL OF REPEATED WORDS AS A FUNCTION OF INTRALIST VARIABILITY

von W right J. M. Free recall of repeated words as a function of intralist variability. Scand. J. Psychol ., 1972, 13 , 39–42.—Five "critical" words were repeated 4 times each in constant positions within lists of 80 items. The number of different filler words, and the order of the repeated filler words, was varied between lists. In free recall tests total recall was approximately constant, but the recall of the critical words was significantly better the greater the variation in the intralist context of these words, especially the greater the number of different filler words. The results are interpreted in terms of the encoding variability hypothesis.
