The development of the Minnesota Multiphasic Personality Inventory

The Minnesota Multiphasic Personality Inventory (MMPI) was constructed at the University of Minnesota before and during World War II. In its developmental phase, the MMPI was conceputalized as an efficient way of detecting psychiatric disturbance. The test's construction was made possible by atypical cooperation between psychologists and psychiatrists, within the context of a crisis in the U.S. public mental health care system. The MMPI was designed to meet the diagnostic needs of psychiatrists. As such, it represented the operationalization of medical hegemony. However, the interpretation of the MMPI shifted significantly after the war, reflecting organizational reform in clinical psychology and changing professional relationships between psychologists and psychiatrists.     

An interactive data-generating and answer-correcting system for problems in statistics

A computer-assisted instructional system is described which provides the student with extensive drill and feedback in the application of statistical methods to computer-simulated data. The system consists of three interactive programs that perform the following functions: (1) FILEMAKE creates “source” data for problems in statistics having whatever population characteristics are desired by the instructor; (2) DATASET generates unique data for each student by performing a random modification, based on sampling theory, of the source data; and (3) CORRECT corrects each student’s unique answers to the problem.     

Perceived benefits of using an Internet-based interactive career planning system

Making Better Career Decisions (MBCD) is an Internet-based interactive career planning system designed to help deliberating individuals. The present research examined the benefits of a dialogue with MBCD, by analyzing 712 users’ perceptions of its contribution to their career decision-making process, and locating variables associated with these perceptions. A pre-dialogue and a post-dialogue questionnaire were used to collect the users’ perceptions of its benefits and measure the change in the degree of decidedness. Perceived benefit was derived from participants’ ratings of the degree of progress they had made in their career decision-making process, whether they had learned about additional factors to be considered and their career-related preferences, as well as their ratings of the quality of the list of “promising” career alternatives presented to them during their dialogue with MBCD. This composite perceived benefit was found to be positively associated with the users’ decidedness at the completion of the dialogue with MBCD. Users’ satisfaction with the length and variety of their personal “promising alternatives” list was associated with a higher perceived benefit.     

The Minnesota Multiphasic Personality Inventory-2: A Review

The new version of the Minnesota Multiphasic Personality Inventory, the MMPI-2, is described and critiqued in this article. The MMPI-2 has many positive features such as updated items, new norms, additional validity scales, and additional clinical scales for diagnosing problems not addressed by the original MMPI. There are, however, also many negative features for this test such as problems with the compatibility of code types and the representativeness of the norm group. Much research needs to be done before accurate interpretations can be made for all MMPI-2 profiles and the full potential of the test is realized.     

The interactive evolution of human communication systems

This paper compares two explanations of the process by which human communication systems evolve: iterated learning and social collaboration. It then reports an experiment testing the social collaboration account. Participants engaged in a graphical communication task either as a member of a community, where they interacted with seven different partners drawn from the same pool, or as a member of an isolated pair, where they interacted with the same partner across the same number of games. Participants' horizontal, pair-wise interactions led "bottom up" to the creation of an effective and efficient shared sign system in the community condition. Furthermore, the community-evolved sign systems were as effective and efficient as the local sign systems developed by isolated pairs. Finally, and as predicted by a social collaboration account, and not by an iterated learning account, interaction was critical to the creation of shared sign systems, with different isolated pairs establishing different local sign systems and different communities establishing different global sign systems.     

The adaptive character of the attentional system: statistical sensitivity in a target localization task

A localization task required participants to indicate which of 4 locations contained a briefly displayed target. Most displays also contained a distractor that was not equally probable in these locations, affecting performance dramatically. Responses were faster when a display had no distractor and almost as fast when the distractor was in its frequent location. Conversely, responses were slower when targets appeared in frequent-distractor locations, even thou targets were equally likely in each location. Negative-priming effects were reliably smaller when targets followed distractors in the frequent-distractor location compared to the rare-distractor location, challenging the episodic-retrieval account Experiment 2 added a 5th location that rarely displayed distractors and never targets, yet responses slowed most when distractors appeared there. The results confirmed that the attentional system is sensitive to first- and higher-order statistical patterns and can make short- and long-term adjustments in preferences based on prior history of inspecting unsuccessful locations.     

Minnesota Employment Counselor Activities

Employment counselors, counselor supervisors, managers, and counselor educators were surveyed in Minnesota concerning the amounts of time that are now spent and should be spent in eleven employment counselor activities. All respondents generally agreed on the amounts of time that are now spent and should be spent in the activities. They also agreed that there should be significant increases (p > .05) in the amounts of time that should be spent in counseling, teaching, and research/follow-up, and decreases in the amounts of time that should be spent in selection/intake and records/clerical activities. Employment counselors in main offices indicated that they now spend significantly less time than counselors in subordinate offices in counseling, consulting, and staff activities, and significantly more time in testing.

The advantage of being left-handed in interactive sports

As compared with their prevalence in the general population, left-handers are overrepresented in the expert domain of many interactive sports. This study examined to what extent this is due to negative perceptual frequency effects—that is, whether the greater frequency of tennis matches with right-handed opponents makes it possible to discriminate the stroke movements of right-handed players more precisely. Fifty-four right-handed and 54 left-handed males in three equal-sized groups of varying levels of tennis expertise (national league experts, local league intermediates, and novices) completed a tennis anticipation test in which they had to predict the subsequent direction of an opponent’s temporally occluded tennis strokes on a computer screen. The results showed that all three groups were better at predicting the direction of strokes by right-handed players. This supports the hypothesis that the overrepresentation of left-handers in the expert domain is partly due to perceptual frequency effects.     

A pseudoperceptual display system for investigating human statistical decision processes

A CRO display system is described in which a random sequence of dots appears on the CRO derived from a Gaussian distribution with a specified mean and standard deviation. Os are required to make judgments about the statistical parameters of the distributions.     

The automaticity of visual statistical learning

The visual environment contains massive amounts of information involving the relations between objects in space and time, and recent studies of visual statistical learning (VSL) have suggested that this information can be automatically extracted by the visual system. The experiments reported in this article explore the automaticity of VSL in several ways, using both explicit familiarity and implicit response-time measures. The results demonstrate that (a) the input to VSL is gated by selective attention, (b) VSL is nevertheless an implicit process because it operates during a cover task and without awareness of the underlying statistical patterns, and (c) VSL constructs abstracted representations that are then invariant to changes in extraneous surface features. These results fuel the conclusion that VSL both is and is not automatic: It requires attention to select the relevant population of stimuli, but the resulting learning then occurs without intent or awareness.     

The knowledge content of statistical data

An information-theoretic framework is used to analyze the knowledge content in multivariate cross classified data. Several related measures based directly on the information concept are proposed: the knowledge content (S) of a cross classification, its terseness (Zeta), and the separability (Gamma _X ) of one variable, given all others. Exemplary applications are presented which illustrate the solutions obtained where classical analysis is unsatisfactory, such as optimal grouping, the analysis of very skew tables, or the interpretation of well-known paradoxes. Further, the separability suggests a solution for the classic problem of inductive inference which is independent of sample size.
