On competence and ethicality in psychodiagnostic assessment

To function competently, psychodiagnosticians must have an accurate sense of what their tests can and cannot do. To function ethically, they must act accordingly--expressing only opinions that are consonant with the current status of validity data. Psychologists who extol tests as doing more than is commonly known they can or who denigrate them as doing less than is commonly known they can are behaving unethically.     

Testing some attribution-emotion relations in the People's Republic of China

We conducted a questionnaire study to test the generality of attribution-emotion relations to individuals in the People's Republic of China. Replications of prior findings of studies conducted with American subjects were reported: (a) High effort and success enhanced interpersonal evaluations when ability, effort, and outcome information were provided; (b) affective communications of pity, anger, and guilt were respectively used to infer low ability, lack of effort, and teacher as causes of failure; (c) effort and ability levels were inferred from the presence or absence of anger reactions; and (d) controllable causes of a broken social contract were expected to result in anger from others. Chinese and American respondents also indicated what situations would arouse the affects of anger, guilt, pity, pride, and shame. We found no evidence for the characterization of Chinese as (a) emphasizing effort over ability as a cause of achievement outcomes or (b) de-emphasizing the importance of personal achievement and stressing group goals and accomplishments.     

The effect of repetition on iconic memory

The present experiment examined the influence of repetition on iconic memory using the Sperling (1960) procedure. It was assumed that the whole-report procedure would estimate only information available from a somewhat more permanent memory system than the icon, while the partial report would estimate both that information and the information available in the icon. The difference between the whole and partial report was assumed to measure information available only in the icon. Across a series of 160 displays one particular display occurred half the time (80 repetitions). The results indicated that the repetition influenced recall from the more permanent memory system assessed by whole report, but had no influence on the information available from the icon (partial report minus whole report).     

Response cost and the aversive control of human operant behavior

The effects of cost (point-loss per response) upon human avoidance, escape, and avoidance-escape behavior maintained by PLPs (point-loss periods) were investigated. Cost had a marked but differentially suppressive effect upon responding under all schedules. The greatest number of PLPs taken under cost occurred on the escape schedule. In most instances PLPs were more frequent on the avoidance-escape schedule than on the avoidance schedule under cost. Inferior avoidance performance appeared only under cost conditions. Under no-cost, all subjects (Ss) successfully avoided all PLPs after the first hour of conditioning. These results indicate that the development and maintenance of human avoidance and escape behavior may, in part, be dependent upon response cost conditions. Aversive control of human operant behavior may be limited without an adequate specification of response-cost conditions.     

Some effects of response cost upon human operant behavior

Three experiments are reported which investigated the effects of cost (point loss per response) upon human-observer responses maintained by VI and FI schedules of reinforcement (acquisition of points via critical-signal detections). (I) Cost attenuated VI response rates without substantially disturbing the constancy of responding, regardless of the presentation sequence of the no-cost and cost conditions. (II) FI scalloping appeared only under cost conditions. Under no cost, a constant rate of responding (similar to VI performance) characterized inter-reinforcement intervals. Exposure to cost did not prevent the recovery of previously established no-cost baselines. (III) FI irregularities, analogous to those commonly observed under FI reinforcement schedules, may be produced by different temporal presentations of the no-cost and cost conditions.

The results of all three experiments emphasize the importance of cost as a factor in the maintenance of human behavior on schedules of positive reinforcement.

     

A Survey of Undergraduate Women's Social Regulations

Data concerning women undergraduates' social regulations in a selected number of coeducational colleges and universities were collected in order to identify liberal regulations in use or under consideration in these institutions grouped according to size, control, and regional location. The collected information supported considerable liberalization in the areas of room and apartment visiting, off-campus living, clothing, sign-out, curfew hours, and coeducational residence halls. Larger respondent institutions' regulations and those of Western institutions evidenced the most liberalization, while regulations of public-control and private-control institutions were considered equally liberal.     

A note on the use of mood's likelihood ratio test for item analyses involving 2 × 2 tables with small samples

Mood's likelihood ratio test is generally considered an unreliablex ² approximation in 2 × 2 contingency tables containing expected cell frequencies less than five. Probability values were computed for 60 such tables as part of an item analysis for two 30-item alternate forms of a measure. The rank orders of the items, from best to worst differentiators, as determined separately by Mood's test and by Fisher's exact test correlated .97 for one form and .96 for the other.
