Deindividualization,Interpersonal Affect and Productivity in Laboratory Task Groups1

In pursuit of efficiency, formal organizations often create deindividualized, uniqueness-depriving environments. The laboratory experiment reported here tests the effects of another's failure to acknowledge one's individuality on interpersonal affect and willingness to help that person. Undergraduate business students were shown a set of bogus ratings representing their task group leader's perceptions of them on 30 personality traits and 10 occupational interests. The ratings indicated that the group leader believed the subject was extremely similar (non-unique) or somewhat similar (unique) to the typical college student. In a highly individualistic culture another's failure to recognize one's uniqueness should be experienced as unwarranted harm and evoke responses mediated by the negative norm of reciprocity. As expected, subjects receiving non-unique feedback volunteered fewer hours to help the group leader perform his or her duties and were less productive when the group leader was believed to benefit from their effort. In spite of these behavioral effects, attitudes toward the leader were not influenced by the uniqueness feedback. After recognizing limits to generalizability, implications for behavior in deindividualized organizations are discussed.     

The double standard in age-discrepant relationships

If a double standard of aging exists, the relationship in which the female is older should be seen more negatively than the more traditional male-older relationship. This study examined the effects of both degree of age discrepancy and sex of the older person on attributions of success for relationships in both adult and adolescent samples. Both samples rated the highly discrepant female-older relationship (18 years difference) least probable of success. Level of discrepancy and sex of older person were significant factors for both groups. Surprisingly, both adult and adolescent males, in contrast to females, did not show the double standard in evaluating moderately discrepant relationship (7 years).     

Solving the eyewitness problem

Faulty eyewitness testimony is a major source of wrongful convictions. Four solutions are examined to safeguard against mistaken testimony having undue impact: (1) to overturn any conviction based solely on the uncorroborated testimony of a single eyewitness, (2) to require that an attorney be present at any pretrial identification procedure, (3) to allow an expert to testify during the trial about factors of perception and memory that could affect a witness's accuracy, and (4) to have the judge deliver a cautionary instruction to the jury, admonishing them to carefully scrutinize eyewitness testimony, or to educate them about such testimony. Each alternative is discussed within the context of psychological research and legal cases.     

On the ability to inhibit simple and choice reaction time responses: a model and a method

This article reports four experiments on the ability to inhibit responses in simple and choice reaction time (RT) tasks. Subjects responding to visually presented letters were occasionally presented with a stop signal (a tone) that told them not to respond on that trial. The major dependent variables were (a) the probability of inhibiting a response when the signal occurred, (b) mean and standard deviation (SD) of RT on no-signal trials, (c) mean RT on trials on which the signal occurred but subjects failed to inhibit, and (d) estimated RT to the stop signal. A model was proposed to estimated RT to the stop signal and to account for the relations among the variables. Its main assumption is that the RT process and the stopping process race, and response inhibition depends on which process finishes first. The model allows us to account for differences in response inhibition between tasks in terms of transformations of stop-signal delay that represent the relative finishing times of the RT process and the stopping process. The transformations specified by the model were successful in group data and in data from individual subjects, regardless of how delays were selected. The experiments also compared different methods of selecting stop-signal delays to equate the probability of inhibition in the two tasks.     

The onset of stuttering following drug overdose

Recently, some attention has been focused on acquired stuttering, disfluencies that begin in adulthood. The nature of acquired stuttering differs in several respects from developmental stuttering. A case of acquired stuttering following drug overdose is presented and contrasted with previously reported cases. The case is noteworthy in that, while many characteristics of acquired stuttering are evidenced, several symptoms associated with developmental stuttering are also observed. The findings are discussed in terms of a possible link between developmental and acquired forms of stuttering.     

A note on interobserver reliability for sequential data

It is well accepted that reliability measures based on simple frequency counts of designated codes are inappropriate for sequential analysis. The stricter point-by-point method, however, is problematic, particularly because it is too strict. It is suggested that a less strict reliability measure based on the number of transitions be used. This method also avoids problems encountered with the point-by-point method and another less stringent method.     

Leading questions and the eyewitness report

A total of 490 subjects, in four experiments, saw films of complex, fast-moving events, such as automobile accidents or classroom disruptions. The purpose of these experiments was to investigate how the wording of questions asked immediately after an event may influence responses to questions asked considerably later. It is shown that when the initial question contains either true presuppositions (e.g., it postulates the existence of an object that did exist in the scene) or false presuppositions (e.g., postulates the existence of an object that did not exist), the likelihood is increased that subjects will later report having seen the presupposed object. The results suggest that questions asked immediately after an event can introduce new—not necessarily correct—information, which is then added to the memorial representation of the event, thereby causing its reconstruction or alteration.

Recognition and recall as measures of long-term retention

Acquisition and retention of a list of paired associates were measured either by cued recall or by multiple-choice recognition. The method of testing used during original learning was combined factorially with the type of test administered after a 1-week interval. Speed of learning to criterion under the two procedures was comparable. Long-term recognition was substantially higher than recall. This difference did not interact significantly with the method of learning. Recall benefited substantially from a prior test of recognition, but there was little effect when the order of tests was reversed. It is concluded that (a) both occurrence and retrieval information were stored under each condition of learning, and (b) occurrence information is less subject to forgetting than retrieval information.
