Ineffective deception in conformity research: Some causes and consequences

Suspiciousness of deception threatens the internal validity of the conformity experiment, and analyses suggest it is becoming more widespread. After being led to believe their own ability in a visual judgment task was higher, lower, or the same as the ability of the other group members, 65 undergraduate women made visual and informational judgments in the Crutchfield apparatus. Major findings include treatment effects on suspiciousness, less conformity by suspicious Ss, and ‘significant’ treatment effects on conformity only when suspicious Ss were removed from the analyses. Measures of self-confidence and confidence in others were significantly related to and likely determinants of suspiciousness. Implications for improving deception in conformity research are discussed.     

Sex and coding strategy effects on reaction time to hemispheric probes

Two experiments were conducted to investigate the influence of coding instructions on cerebral laterality differences. Experiment I required 20 subjects (10 female) to use either rehearsal or imagery coding strategies in a recognition task with word probes to the right and left hemispheres. No hemispheric differences were found, but sex of subject was found to be related to coding strategy. Ten subjects (5 female) in Experiment II performed a similar task, except picture probes were used. Subjects using rehearsal coding responded faster to left-hemisphere probes, but faster to right-hemisphere probes when imagery coding was employed. The differing laterality effects in these experiments were attributed to naming responses implicitly required in Experiment II.     

Recognition memory for deducible information

Recent research in language comprehension indicates a constructive encoding process in which the linguistic input is transformed into some more general semantic structure which is stored. In attempting to characterize the nature of such structures, some conflicting findings have been observed for paragraphs which describe similar set-theoretic relations, linear orderings and set inclusions. While the linear ordering research supports the constructivist theory, the set inclusion work does not. The set inclusion studies, however, employed true-false tests and not the usual recognition tests. The present study investigated the processing of set inclusion paragraphs in a self-paced study/recognition test paradigm. Results supported the constructivist theory and were contrary to predictions based upon the previous set inclusion research. Subjects were unable to differentiate between presented information and unpresented deducible information. These results were discussed in terms of accuracy constraints of different tasks on memorial performance and a possible interaction of Type of Test by Universal Quantification.     

Sequential search processes in long-term memory

In an experiment employing the symbol-element recognition task (Mohs, Wescourt, & Atkinson, 1975), subjects first learned six lists consisting of four words (elements) each. Each list was associated with a unique consonant (symbol). Subsequently, on each of a series of test trials, subjects were presented with one, two, or four symbol-element pairs. A positive response was required if all test words were correctly paired with their associated consonants and a negative response if any one test word was incorrectly paired with a consonant. Of primary concern was the way reaction time (RT) varied with number of pairs presented, the type of response required, and, on negative trials, the position of the mismatched pair in the test display. RT increased with the number of pairs presented on a trial and the increase was greater for positive than for negative trials. For negative pair trials, RT increased with the distance of the mismatched pair from the top of the test display. On negative trials in which the top pair in the test display was the mismatched pair, RT increased with the total number of pairs presented on the trial. A serial, probabilistic order of processing model is proposed to account for these results, and applications of the model to other paradigms are discussed.     

The legalization of the school psychologists’ world

Discusses the increasing tendency of legal rules to shape school psychologist's conduct. Court cases, legislation, and empirical studies treating with this issue are analyzed. The article suggests that “the legalization of the school psychologist's world” may afford an opportunity to reshape, in more “non-formal” and collegial ways, relationships with other school professions, students, and parents.     

Handling negative inputs: On the plausible equity formulae

Equity research has been based on defining formulae that do not necessarily imply the hypotheses thought to have been derived from them and that are not consistent with empirical data cited as supporting equity theory. Neither Adams' (1965) ratio definition nor Walster et al.'s (1970, 1972, 1973) formula satisfy the fundamental criterion that, when equity holds, outcome should be an increasing function of input. Six formulae that do satisfy this fundamental criterion (including Adams' ratio definition restricted to positive ratios, Walster et al.'s revision of their formula, three formulae generated by a simple constructive procedure, and an exponential definition) are compared with respect to 11 other criteria and with respect to their predictions of the results of two thought experiments.     

Self-consciousness, self-awareness, and self-attribution

Self-awareness was either manipulated by a mirror (experimental) or not (control). Subjects were selected for being high or low in private self-consciousness (disposition to attend to one's thoughts, feelings, motives). Private self-consciousness had a stronger effect on self-attributions than did self-awareness. These findings have implications for attribution, self-consciousness, and the relationship between manipulations and dispositions.     

Cardiovascular responses to avoidance conditioning in the dog: Effects of alpha adrenergic blockade

Laboratory dogs were trained to press a response panel to postpone shocks during daily one-hour avoidance conditioning periods. Each dog was also confined in the experimental environment for 5 hours prior to the avoidance periods. Blood pressure and heart rate were monitored continuously during these experiments from chronically indwelling arterial catheters. Extended training resulted in the emergence of a cardiovascular response pattern during the pre-avoidance interval characterized by gradual increases in blood pressure together with decreases in heart rate. Elevations in both blood pressure and heart rate were sustained during the avoidance periods. During sessions in which alpha adrenergic activity was suppressed by phenoxybenzamine, absolute levels of blond pressure were found to be lower than during control (non-drug) sessions, but a progressive rise in blood pressure continued to be observed during pre-avoidance. These results suggest that sustained cardiovascular responses during avoidance periods are associated with activation of the sympathetic nervous system, but that the gradual rise in blood pressure during pre-avoidance is due to other factors.     

Selective looking with minimal eye movements

Neisser and Becklen (1975) showed that one of two visually superimposed events could be followed without interference from the other. Neisser and Becklen allowed their subjects to move their eyes without restriction. The present experiment eliminated the possibility that the tracking eye movements of the subjects, which could have been used to maintain the stability of the event on the retina, were instrumental in following the desired event. The experiment of Neisser and Becklen was essentially replicated with one exception: subjects were required to fixate a spot in the center of the visual field during one-half of the trials. It was no more difficult for subjects to follow either a single event or one of two superimposed events when fixation was required. The suggestion was made that eye movements do not initiate a perceptual act, but rather are dependent upon perceptual anticipations.     

Classical aversive conditioning of heart rate in curarized rats at different blood gas levels

In an effort to examine whether normal blood gas tensions were essential for conditioning, paralyzed rats received a classical aversive heart rate (HR) conditioning session while respirated at different peak expired CO₃ values. After the session, arterial blood was drawn for analysis. That peak expired CO₂ was effective in manipulating Pco₂ was indicated by a significant correlation (r = 0.594, df = 17, P < 0.05). In addition, only rats with blood gas values similar to those of anesthetized controls displayed a discriminated HR CR. These animals also had lower baseline HRs and greater HR variability. Further, 7 of the 9 rats with normal blood gas values were respirated at peak expired CO₂ values from 5.0–5.1 per cent, and no animal ventilated within this range displayed abnormal values. These findings suggest that previous difficulties in obtaining classical and operant conditioning in paralyzed animals may, in part, be attributable to inadequate ventilation.
