Group Decision as a Technique for Obtaining Compliance: Some Added Considerations Concerning How Altruism Leads to Callousness

Bennett (1955) reported that a critical condition for producing Lewin's (1958) classic group discussion-decision effect (is., high compliance with a request from an authority figure) was a group consensus strongly favoring compliance. This finding prompted investigation of variables potentially affecting such a consensus. A first study found that group consensus is significantly less likely to favor compliance if subjects are allowed to make a majority rather than an individual decision. Group size had no significant effects on decision-making. A second study replicated this effect and investigated several explanations for it. These results suggest that, at least when compliance is not in the subjects' best interest, the Lewinian group discussion-decision effect will be less likely to be found if a majority decision role is followed as opposed to an individual decision rule. The implication of these data for social engineering is discussed.     

Semantic components in children's errors with pronouns

In the presence of the experimenter and two dolls, children were asked to respond to sentences containing pronous which required distinctions to be made on the basis of person, number, and gender, such as “Point tomy (your, his, her, our, their) feet.” Errors tended to maintain distinctions; for example,we was treated as if it meantI (maintaining first person) orthey (maintaining plural) more often than could be accounted for by a response-bias model. Furthermore, there were consistent individual differences in the kinds of distinctions that were difficult; some subjects has more trouble with number, others with person. These findings support the notion that errors made during acquisition result from dropping only part of the correct meaning, and they suggest that individuals may differ in the relative strengths of different components.     

Phonemic stage not necessary for reading

Subjects can classify, as not making sense, phrases which sound as though they make sense, e.g. “tie the not”, as quickly as other phrases which do not even sound right, although they make more errors on the former. When asked whether or not phrases sound sensible regardless of how the phrases look, they are faster and make fewer errors on the phrases that look sensible as well as sound sensible. It is concluded that meaning can be efficiently derived from a visual analysis of text without the use of an intermediate phonemic code, or “inner speech”, although such a code may be used some of the time.     

Effects of wage inequities on work attitudes and performance

A replication and extension of the Adams and Jacobsen (1964) investigation of inequity theory was carried out using a 3 × 2 experimental design with three levels of compensation and two levels of qualifiedness. This design included an overcompensated condition in which the overpayment was not confounded with unqualifiedness, thereby allowing a comparison of differential predictions from inequity and expectancy theory. Comparisons of over and underpayment conditions were also made to test the differential threshold hypothesis of inequity theory. Attitudinal as well as performance data were collected to investigate the possibility of differing modes of inequity reduction.The major finding in the present study was that variations in manipulated perceptions of qualifiedness produced significant effects upon both quality and quantity measures of work behavior while induced variations in the amount of anticipated compensation only affected quality of work. The qualified conditions produced fewer pieces of higher quality. This finding was discussed from the point of view of inequity theory as well as an alternative “self-esteem” explanation.Differences in work performance across pay levels were nonsignificant with the exception of a work quality measure in which the overpaid qualified group produced significantly more errors than the standard pay-qualified group. Possible interpretations of these findings were discussed and a range of conditions which may affect perceptions of inequity were considered.     

Is social comparison irrelevant for producing choice shifts?

After 15 years of research on group induced shifts in individual choice, two hypotheses, social comparison (involving image maintenance) and persuasive arguments (involving attitude change), have emerged as the leading explanatory contenders. Burnstein and his associates have recently reported a series of studies that they feel clearly establish the persuasive arguments hypothesis as the best explanation for the shifts. The present paper takes issue with their conclusion. A study is presented that supports a social comparison interpretation of one of the experiments reported in Burnstein and Vinokur (Journal of Experimental Social Psychology 1973, 9, 123–137). In addition, a critical analysis of several other key studies reported by Burnstein and his associates yields the conclusion that neither hypothesis completely accounts for the available data. Rather, both image maintenance and attitude change processes may operate in a complementary manner, with persuasive arguments facilitating the shifts motivated by social comparison. Parallels are drawn between the factors that affect choice shifts and those that affect conformity behavior.     

Increased reinforcement when timeout from avoidance includes access to a safe place

Three experiments investigated the reinforcing value of access to a safe place during timeout from an avoidance schedule. Rats were trained on conjoint schedules in which responding both postponed shock on a free-operant avoidance schedule and produced periods of timeout on fixed-ratio schedules. In some conditions, a shelf was inserted into the operant chamber during timeout, enabling subjects to get off the grid floor. The combination of timeout and shelf maintained substantially higher response rates than the baseline avoidance schedule with ratio requirements as high as 90 (Experiment I). Adding the shelf to timeouts in one component of multiple fixed-ratio schedules of timeout resulted in higher response rates in the component where the shelf was included (Experiment II). When timeouts with and without the shelf were arranged on concurrent schedules, the shelf-timeout combination was preferred, even when of shorter duration than timeout alone (Experiment III). In all three experiments, subjects climbed on the shelf, although all shocks were cancelled during timeout periods. The results could not be accounted for solely in terms of the reinforcing properties of changes in shock rates, but required an interpretation that ascribed conditioned reinforcing value to stimuli associated with such changes.     

Response-dependent and response-independent timeout from an avoidance schedule

While rats were responding in a single-lever apparatus to avoid electric shock, a signal was presented and followed by a 5-min timeout period when all shocks were omitted. For the response-dependent member of each yoked pair, the first response 60 sec after onset of the pre-timeout signal terminated the signal and initiated timeout. The other, yoked animal was exposed to the same sequence except that signal termination and timeout onset were response independent. Under the response-dependent condition, response rates in the presence of the signal increased relative to baseline rates. Rate increases also occurred when timeout was response independent, but were of lesser magnitude and reliability. Subsequent reversal of the yoking arrangement produced stable and equivalent rate increases under both conditions. Other findings were that increased rates in the presence of the signal diminished when timeout was omitted but were maintained for a time on an avoidance-extinction baseline. In general, the results supported the conclusion of previous experiments that timeout from avoidance can serve as a positive reinforcer. The finding that response-independent presentation of timeout produced rate increases, particularly after a history with response-dependent timeout, was interpreted in terms of adventitious reinforcement of previously established behavior.
