The origins of word learning: Brain responses of 3‐month‐olds indicate their rapid association of objects and words

The present study explored the origins of word learning in early infancy. Using event‐related potentials (ERP) we monitored the brain activity of 3‐month‐old infants when they were repeatedly exposed to several initially novel words paired consistently with each the same initially novel objects or inconsistently with different objects. Our results provide strong evidence that these young infants extract statistic regularities in the distribution of the co‐occurrences of objects and words extremely quickly. The data suggest that this ability is based on the rapid formation of associations between the neural representations of objects and words, but that the new associations are not retained in long‐term memory until the next day. The type of brain response moreover indicates that, unlike in older infants, in 3‐month‐olds a semantic processing stage is not involved. Their ability to combine words with meaningful information is caused by a primary learning mechanism that enables the formation of proto‐words and acts as a precursor for the acquisition of genuine words.     

Hypnoanalyse – Ein Stiefkind der Psychoanalyse

Goal of this article is to present the manifold methods and techniques of modern hypnotherapy/hypnoanalysis and to show the possibilities for linking them to traditional psychoanalytical methods. In the introduction, clarification of concepts and a short historical overview is given. The phenomenology of the hypnotical state and its assessment from a psychoanalytical and a non-psychoanalytical view either follows. In this connection the topic of meditation is shortly discussed. In the main part a definition of hypnoanalysis is given, the most important hypnoanalytical methods are described and demonstrated by case studies. The question whether psychoanalysis is to be considered as a trance therapy, is also discussed. Free association in hypnotical trance is especially recommended with patients having difficulties to reach their own feelings.     

Are occupational interests hormonally influenced? The 2D:4D-interest nexus

Occupational interests constitute a psychological variable with pronounced sex differences. Whereas males are more interested in things, females primarily take an interest in people. As various studies with mammals and humans documented the role of androgen exposure on sex-typical behavior, we assumed that androgen levels are associated with occupational interests. In our study, we used 2D:4D digit ratio as an indicator of prenatal androgen levels and finger lengths as an indicator of post-pubertal androgen levels. Occupational interests were measured with a standard interest inventory. We hypothesized that finger lengths and ratios indicating high androgen levels are associated with stronger interests in things and weaker interests in people. All measures were gathered using an online interest inventory thereby leading to sufficient statistical power (N = 8646). Results partly confirmed our hypotheses. We found significant correlations between finger lengths and interests in things for males. Moreover, in the case of males we identified significant correlations between finger lengths (positive) as well as digit ratios (negative) with realistic interests and significant correlations between finger lengths (negative) and social interests, which are a marker variable of the people-things dimension.     

Viewpoint dependency in the recognition of dynamic scenes

In 3 experiments, the question of viewpoint dependency in mental representations of dynamic scenes was addressed. Participants viewed film clips of soccer episodes from 1 or 2 viewpoints; they were then required to discriminate between video stills of the original episode and distractors. Recognition performance was measured in terms of accuracy and speed. The degree of viewpoint deviation between the initial presentation and the test stimuli was varied, as was both the point of time presented by the video stills and participants' soccer expertise. Findings suggest that viewers develop a viewpoint-dependent mental representation similar to the spatial characteristics of the original episode presentation, even if the presentation was spatially inhomogeneous.     

Do film cuts facilitate the perceptual and cognitive organization of activitiy sequences?

Film depictions of activities possess two kinds of structures--namely, the structural features of the depicted activities themselves and a formal structure defined by film cuts. The former structure is used by everyday observers for perceptually and cognitively unitizing the continuous flow of events into comprehensible entities. It seems conceivable that cuts can serve a similar unitizing purpose for film viewers. For each of two different activity sequences, two film versions were produced. Throughout each film version, cuts were placed either at breakpoints or at nonbreakpoints. In a 2 x 2 (activity sequence x film version) factorial design, 40 subjects segmented the film during viewing and recalled the film content after viewing in a detailed protocol. Segmentation behavior depended primarily on the occurrence of breakpoints and was largely unaffected by the occurrence of cuts. Cuts accompanying a breakpoint lead to more detailed recall protocols for these sections of the film.

An evaluation of exact methods for the multiple subset maximum cardinality selection problem

The maximum cardinality subset selection problem requires finding the largest possible subset from a set of objects, such that one or more conditions are satisfied. An important extension of this problem is to extract multiple subsets, where the addition of one more object to a larger subset would always be preferred to increases in the size of one or more smaller subsets. We refer to this as the multiple subset maximum cardinality selection problem (MSMCSP). A recently published branch‐and‐bound algorithm solves the MSMCSP as a partitioning problem. Unfortunately, the computational requirement associated with the algorithm is often enormous, thus rendering the method infeasible from a practical standpoint. In this paper, we present an alternative approach that successively solves a series of binary integer linear programs to obtain a globally optimal solution to the MSMCSP. Computational comparisons of the methods using published similarity data for 45 food items reveal that the proposed sequential method is computationally far more efficient than the branch‐and‐bound approach.     

Psychometric Evaluation of the Italian Adaptation of the Test of Inferential and Creative Thinking

This article describes the psychometric properties of the Italian adaptation of the Analyse des Schlussfolgernden und Kreativen Denkens (ASK; Test of Inferential and Creative Thinking) for measuring inferential and creative thinking. The study aimed to (a) supply evidence for the factorial structure of the instrument, (b) describe its reliability in terms of internal consistency, and (c) explore its convergent and discriminant validity. The examinees were 284 high school students and adult graduates. Both exploratory and confirmatory factor analyses were used to examine the dimensional structure. The 2-factor model provided an acceptable fit for the empirical data. As expected, stronger correlations were found among the subscales within the same construct domains compared to correlations among the subscales from the different construct domains. The psychometric qualities of the ASK appeared fairly good, thereby suggesting that it might be helpful in several application fields, including academic and professional guidance, human resource selections, and job placement.     

Testing Mean Differences among Groups: Multivariate and Repeated Measures Analysis with Minimal Assumptions

To date, there is a lack of satisfactory inferential techniques for the analysis of multivariate data in factorial designs, when only minimal assumptions on the data can be made. Presently available methods are limited to very particular study designs or assume either multivariate normality or equal covariance matrices across groups, or they do not allow for an assessment of the interaction effects across within-subjects and between-subjects variables. We propose and methodologically validate a parametric bootstrap approach that does not suffer from any of the above limitations, and thus provides a rather general and comprehensive methodological route to inference for multivariate and repeated measures data. As an example application, we consider data from two different Alzheimer’s disease (AD) examination modalities that may be used for precise and early diagnosis, namely, single-photon emission computed tomography (SPECT) and electroencephalogram (EEG). These data violate the assumptions of classical multivariate methods, and indeed classical methods would not have yielded the same conclusions with regards to some of the factors involved.
