An Experimental Study of Black-White Negotiations1

One hundred and forty variables tapping aspects of the subjective culture (characteristic way or perceiving the social environment) of 300 white male students were subjected to two-mode factor analysis. Five subject types emerged from the similarities in the responses of the students to these variables. In the next phase of the study, 88 representatives of these subject types participated in experimental negotiations. Before the negotiations, caucus groups, consisting of six students homogeneous in their pretest scores, decided what positions should be upheld during the negotiations. Following the caucuses, three two-member teams were formed, from each caucus group. The teams negotiated with two-member black teams of confederates of the experimenters. Negotiations focused on three issues, each of which was represented by 10 Thurstone successive-interval method scaled positions. Negotiation outcomes were predicted from the subjective culture measures (r= .42; p < .005). The negotiation outcomes tended to be more predictable from the reference group (caucuses) preferred positions (r= .65) than from individual preferences (r= .36). Negotiators tended to overconform to caucus positions. Behavioral differential scale ratings of black negotiators predicted the outcomes better than semantic differential ratings of these stimuli. The more specific the attitude measured the more predictive it was of negotiation outcomes. Discussion focused on implications for understanding the relationship between attitudes and behavior and the process of black/white negotiations.     

A six-channel PDP-8 interface for nerve impulse data

An interface operating on the I/O bus of the LINC-8 has been built which accepts up to six channels of nerve impulse data simultaneously at rates up to 4,000 pps/channel. By means of a 100-KHz clock and a 17-bit counter, the time of occurrence of each nerve impulse is strobed into one of six 17-bit buffer registers. The strobe causes a program interrupt to occur. Two I/O instructions are used to read the buffers into the PDP-8 accumulator. Additional instructions for skipping on data or overflow, enabling the counter, clearing the overflow flag, and clearing the counter are available.     

The design of ballantines

The shared variance between two variables can be expressed graphically by overlapping circles. A procedure is presented for locating the circles so that the graphical and statistical relations correspond exactly. The procedure does not generalize to the representation of multiple, part, and partial correlations between three or more variables. The reasons for the nonextension are explained, and some alternative graphical representations are suggested.     

The sentence-verification paradigm: A case study of two conflicting aproaches to individual differences

The contrasting approaches of differential psychology and cognitive psychology to the same individual differences data are outlined. Using illustrative data from the Clark and Chase (1972) sentence-picture verification task, four loci of conflict between these two disciplines are identified. These areas of conflict center around issues of (1) theory versus measurement, (2) meaningfulness versus reliability, (3) linearity of relationships, and (4) discontinuities in performance. We conclude on the basis of observed incompatibilities that a simple derivation of differential psychology from cognitive psychology is not likely, but separate development of complementary theories may be possible.     

Things dreamt: a response to Berislav Marusic

Philosophical Studies - Skeptical arguments from dreaming deny that we can know that we are awake. This denial lacks initial credibility to many of us. Often it seems easy to know. A brief...     

Likability and Similarity as Potential Sources of Predictor-Related Criterion Bias in Validation Research

Previous research on the effects of bias in criterion-related validation research has typically involved the use of statistical corrections for halo, leniency, and/or central tendency. We present arguments that likability and similarity of raters to ratees may constitute a form of predictor-related criterion bias. One cannot investigate this form of bias without clear understanding of method, predictor, and criterion constructs and careful direct measurement of each. Measurement and theorizing of method constructs is rarely, if ever, undertaken in criterion-related validation work. The results of a criterion-related validation of the use of quantitative and verbal ability and interview and role-play simulations to predict the performance of 372 federal investigative agents are reported. Using the all-Y LISREL model (Williams & Anderson, 1994), we found that likability and similarity factors were related to interview and role play measures. However, none of these potential "biases" affected both predictor and criterion constructs, hence there was no effect on the estimates of the relationships between the predictors and criteria. Limitations with respect to the generalizability of these results to criterion-related research in which performance data are not as carefully collected as well as advantages and disadvantages of more traditional regression and correlational analyses are discussed.     

Effects of Training Goals and Goal Orientation Traits on Multidimensional Training Outcomes and Performance Adaptability

This research examined the effects of mastery vs. performance training goals and learning and performance goal orientation traits on multidimensional outcomes of training. Training outcomes included declarative knowledge, knowledge structure coherence, training performance, and self-efficacy. We also examined the unique impact of the training outcomes on performance adaptability by predicting generalization to a more difficult and complex version of the task. The experiment involved 60 trainees learning a complex computer simulation over 2 days. The research model posited independent effects for training goals relative to goal orientation traits and independent contributions of training outcomes to the performance adaptability of trainees. The findings were consistent with the proposed model. In particular, self-efficacy and knowledge structure coherence made unique contributions to the prediction of performance adaptability after controlling for prior training performance and declarative knowledge. Implications and extensions are discussed. Copyright 2001 Academic Press.     

A test of major assumptions about behavior change: a comprehensive look at the effects of passive and active HIV-prevention interventions since the beginning of the epidemic

This meta-analysis tested the major theoretical assumptions about behavior change by examining the outcomes and mediating mechanisms of different preventive strategies in a sample of 354 HIV-prevention interventions and 99 control groups, spanning the past 17 years. There were 2 main conclusions from this extensive review. First, the most effective interventions were those that contained attitudinal arguments, educational information, behavioral skills arguments, and behavioral skills training, whereas the least effective ones were those that attempted to induce fear of HIV. Second, the impact of the interventions and the different strategies behind them was contingent on the gender, age, ethnicity, risk group, and past condom use of the target audience in ways that illuminate the direction of future preventive efforts.     

Ethnicity and adolescent substance use

This study focuses on diverse ethnic differences among adolescent substance use, utilizing selected items from the Substance Abuse Subtle Screening Inventory-Adolescent version (SASSI-A). Data were gathered from a large-scale, cross-sequential study of adolescents during the 1993-1996 school years. Exploratory analyses were conducted for 3,711 students on the basis of their responses to a self-administered survey. Results indicated significant ethnic and gender differences for specific SASSI-A items and factor scores, with Hawaiian, "Other," and Caucasian students reporting higher scores than Japanese students and greater scores for female than male students. These findings suggest the need to develop culturally sensitive substance use prevention and treatment strategies that should also take gender differences into consideration for adolescents in Hawai'i.
