An edited translation of the first dissertation in experimental psychology by Max Friedrich at Leipzig University in Germany

Summary The present paper presents an edited translation of the first doctoral thesis in experimental psychology, completed by Max Friedrich at Leipzig University during the Winter Semester of 1879–80. The official degree was awarded in 1880 and the full text was published in the first issue of Wundt's journal Philosophische Studien (Philosophical Studies). In addition to a translation of the original text, the author provides a critical analysis of the methodology and results of Friedrich within the context of modern psychophysics.Support for this project came from grants from the Scholarship Support Fund of The Pennsylvania State University. Appreciation is extended to Doris Grab who ably assisted in the translation process and to Wolfgang Bringmann who was instrumental in this project becoming a reality from its conception in 1975     

Repeating the Errors of Our Parents? Family‐of‐Origin Spouse Violence and Observed Conflict Management in Engaged Couples*

Based on a developmental social learning analysis, it was hypothesized that observing parental violence predisposes partners to difficulties in managing couple conflict. Seventy-one engaged couples were assessed on their observation of parental violence in their family of origin. All couples were videotaped discussing two areas of current relationship conflict, and their cognitions during the interactions were assessed using a video-mediated recall procedure. Couples in which the male partner reported observing parental violence (male-exposed couples) showed more negative affect and communication during conflict discussions than couples in which neither partner reported observing parental violence (unexposed couples). Couples in which only the female partner reported observing parental violence (female-exposed couples) did not differ from unexposed couples in their affect or behavior. Female-exposed couples reported more negative cognitions than unexposed couples, but male-exposed couples did not differ from unexposed couples in their reported cognitions.     

Changes in Late Adolescents and Young Adults’ Attachment,Separation, and Mental Health During Wilderness Therapy

The study explored changes in young adults’ mental health, attachment, and separation from parents during a seven-week wilderness therapy program. Utilizing a longitudinal one-group design, the study examined outcomes of 157 young adults in one wilderness therapy program. From pre to post treatment, participants reported significant improvement in mental health symptoms and interpersonal relationships, as well as increases in the belief that others can be depended upon. Participants reported less resentment and anger towards mothers from pre to post treatment, but an increase in their needs for approval from fathers. The study details a link between young adults’ attachment, independence from parents, and improvement in mental health, suggesting that treatment which targets these links may provide more effective intervention.     

A simplified version of the maximum information per time unit method in computerized adaptive testing

In this article, we propose a simplified version of the maximum information per time unit method (MIT; Fan, Wang, Chang, & Douglas, Journal of Educational and Behavioral Statistics 37: 655–670, 2012), or MIT-S, for computerized adaptive testing. Unlike the original MIT method, the proposed MIT-S method does not require fitting a response time model to the individual-level response time data. It is also computationally efficient. The performance of the MIT-S method was compared against that of the maximum information (MI) method in terms of measurement precision, testing time saving, and item pool usage under various item response theory (IRT) models. The results indicated that when the underlying IRT model is the two- or three-parameter logistic model, the MIT-S method maintains measurement precision and saves testing time. It performs similarly to the MI method in exposure control; both result in highly skewed item exposure distributions, due to heavy reliance on the highly discriminating items. If the underlying model is the one-parameter logistic (1PL) model, the MIT-S method maintains the measurement precision and saves a considerable amount of testing time. However, its heavy reliance on time-saving items leads to a highly skewed item exposure distribution. This weakness can be ameliorated by using randomesque exposure control, which successfully balances the item pool usage. Overall, the MIT-S method with randomesque exposure control is recommended for achieving better testing efficiency while maintaining measurement precision and balanced item pool usage when the underlying IRT model is 1PL.     

Descartes’ Morals

The Children's Act (Act No. 38 of 2005) and its associated regulations allow for virginity tests to be performed on male and female children over the age of 16. This is subject to a number of legislated conditions, including that informed consent should be obtained. In this article I argue that, whilst it is important that the right to social and cultural practice be protected in South Africa, virginity testing is a practice that cannot be morally justified. Firstly, I defend the claim that the practice is inherently unjust. At least some of those subjected to the tests will inevitably experience the undesirable consequences of a false test result. The practice is also discriminatory as it typically and unjustly targets girl children, since boys are far less commonly tested. I argue further that the practice perpetuates a harmful patriarchal social order. Finally, I contend that any attempts to justify this legislation are fatally flawed, because it is fundamentally irrational, since there is no reliable means of testing for virginity.     

Kulturdynamisches Modell der bikulturellen Identit?t

In intercultural psychotherapeutic treatment, the psychological integration of different cultures within an individual has to be involved as an additional developmental dimension. Individual change during the process of migration considered as desirable adaptation has often been conceptualized in terms of a bicultural identity, which includes aspects of the culture of origin as well as aspects of the host culture. The theoretical foundation of the concept of bicultural identity, however, has remained insufficient. The culture-dynamic model presented here differentiates personal and social identity according to the identity concept proposed by Mead (Geist, Identit?t und Gesellschaft, 1988, Suhrkamp, Frankfurt a.?M.). Personal identity is essentially formed by an individual??s culture of origin, while influences of the host culture primarily affect the social identity. For healthy coping with the challenges associated with migration and adequate support of this process in intercultural psychotherapy, it can be assumed that a stabilization of personal identity is required to allow for a dynamization of social identity. Implications for identity constitution in second generation immigrants, in different stages of lifespan development and in the process of learning the language of the host culture are discussed.     

Maternal Sensitivity: Evidence of Stability across Time,Contexts, and Measurement Instruments

Although maternal sensitivity is widely understood as having a direct impact on the quality of the mother–child relationship, empirical evidence supporting this has been inconsistent, possibly because of varied definitions of the construct and limitations of measurements. The Maternal Behavior Q‐Set (MBQS) appears to be a promising measure of sensitivity, showing associations with attachment security (r = .60) higher than those reported (r = .24) in a highly‐regarded meta‐analysis of other sensitivity measures. The present study aimed to further establish the validity and utility of the MBQS by exploring its consistency with a contingency‐based measure of sensitivity, while also seeking evidence of stability across contexts and times. Seventy‐two mothers and their 10‐month‐olds participated in a procedure that included two episodes of Floor Play and Reunions following maternal differential treatment. Mothers were scored on contingent responsivity and warmth. At 12 months, the dyads underwent the Strange Situation Procedure where sensitivity was assessed using a 72‐item version of the MBQS. The findings revealed the stability of maternal sensitivity across times, contexts, and measures. However, linkages applied only to 10‐month scores from reunion, not play, episodes, supporting Pederson and Moran's (1995) assertion that high‐demand circumstances reveal more meaningful differences in maternal sensitivity.

Proactively balancing the validity and legal compliance of personal background measures in personnel management

Despite its proven utility and validity for the prediction of performance, the use of certain biodata questions for selection is being restricted because of fears of charges of discrimination, or of invasion of privacy, arising from increasingly stringent state and federal laws governing employment (Ash, 1989). The objective of this study was to develop alternative items that were valid and also perceived as nondiscriminatory and noninvasive for two biodata subscales in a well-researched biographical inventory. The newly developed subscales had acceptable KR-20 reliability coefficients. Sizeable and significant correlations between the corresponding original and newly developed subscales attested to the latter's construct validity. The performance criterion validity of the new subscales was demonstrated by significant correlations with both salary and with level of organizational functioning, which were regarded as measures of the individual's worth to the organization. The results of the present study encourage the expectation that biodata items can be constructed that are (1) valid, (2) in compliance, and (3) with a sufficiently low level of perceived invasiveness that will allow both the applicant and the test user to be comfortable with their use.     

Perception of clusters in statistical maps

Two experiments observed performance on a cluster identification task across a variety of common statistical maps. Stimulus maps displayed mortality rates for several diseases and subjects had to identify regions of the map that were perceived to form a cluster of particularly high (or low) mortality. Subjects marked the perceived centroid of each cluster, and analyses focused on the dispersion of centroid location across subjects. Under these circumstances, monochrome classed choropleth maps were found to minimize dispersion, compared to a two opposing colours scheme, a dot density map, a pie map, and a categorical (hue-based) colour scheme. Maps using a familiar geographical unit (i. e. a U. S. state) supported better recall of the information than maps using less familiar and smaller geographical units. The results were found to be interpretable within current cognitive theory.
