The word order problem in agrammatism : II. Production

This study demonstrates that agrammatic aphasics have difficulty describing relations that are signified by the order of noun phrases around verbs or prepositions. The word order deficit is found in a Sentence Order Task, in which written words must be arranged linearly to form a sentence, as well as in oral production. Ordering tendencies reflect factors like animacy or potency, rather than the systematic use of syntactic rules. These results point to a fundamental syntactic disorder in agrammatism.     

Semantic mechanisms in paralexia

This study explores the effects of semantic constraints on the occurrence of paralexic responses in two patients who tend to produce semantic errors in reading aloud. In the first experiment, semantic constraints were provided by using words as proper names (e.g., “brown” vs. “Sam Brown”), and in the second by using short, highly familiar phrases to restrict the meaning of the target word (e.g., the polar bear; green with envy). These constraints were found to be effective in reducing the frequency of paralexic errors.     

CHANGING PERSPECTIVES IN COGNITIVE NEUROPSYCHOLOGY*

Neuropsychology, the study of behavioral and mental disorders resulting from brain damage, seeks to integrate observable mental and motor functions with knowledge of nervous system structure and function. The first part of this paper deals with the empirical and theoretical contributions that arise from the study of classical clinical syndromes, from cognitive psychology based on information processing, and from the computationally-based study of complex cognitive systems such as language. The second part of this paper deals with two areas of neuropsychological research, memory mechanisms and motor behavior, that exemplify some of the methodological and conceptual problems that arise in trying to bridge animal and human studies, or psychological and physiological levels of analysis. Suggestions are made for how greater progress can be made by considering fundamental processes, and, by focusing on levels of abstraction useful to both the psychologist and the biologist. The last part of the paper briefly discusses some of the major issues involved in an attempt to establish a neurobiologically-based theory of human behavioral and mental function.     

Cultural, contextual, and intrapersonal predictors of risky sexual attitudes among urban African American girls in early adolescence

The role of cultural factors in explaining sexual attitudes among African American urban girls, aged 10-13 years, was investigated in this study. The authors predicted that girls with higher school interest, family cohesion, religiosity, and behavioral self-esteem would endorse less risky sexual attitudes. Also, older girls were expected to have more risky sexual attitudes than younger girls, and girls from 1- rather than 2-parent households were expected to have more risky sexual attitudes. The authors hypothesized that ethnic identity and gender role orientations would contribute to explaining variability in sexual attitudes after controlling for contextual and intrapersonal variables. A questionnaire containing measures of the study constructs was administered to 214 girls who were participants in a substance abuse prevention program. Pretest data were used in analyses. A final regression model accounted for 23% of the variance in sexual attitudes. Age and behavioral self-esteem were significant predictors, with younger teens and teens with higher behavioral self-esteem having less risky sexual attitudes. Cultural variables contributed to explaining variation in sexual attitudes after other variables were controlled for. Higher levels of ethnic identity were associated with less risky sexual attitudes. A masculine gender role orientation was associated with more risky sexual attitudes.     

Religious Unbelief in Three Western European Countries: Identifying and Characterizing Unbeliever Types Using Latent Class Analysis

The different forms of religious unbelief are still much of an open question. Using data (N = 4,404) from three European countries—Finland, Denmark, and the Netherlands—we sought to identify underlying unbeliever groups among those with the strongest disbelief in God (N = 2,258). Latent class analyses were conducted on the nontheistic supernatural beliefs of this subsection of participants, resulting in the same three unbeliever groups in each country: analytic atheists, spiritual but not religious (SBNR), and uncertain nonbelievers. Next, we explored these groups on a variety of dimensions, especially on the group members’ attitudes to religion, certainty of beliefs, cognitive dispositions, and worldview. One-way analyses of variance (ANOVAs) revealed similarities as well as distinct characters for each of the latent groups. The groups differed most in intuitive thinking style, overmentalizing bias, and other ontological confusions. To compare the latent groups to all other individuals who took part in the study, two discriminant analyses were run with all participants. This resulted in four meaningful dimensions that supported and extended the ANOVAs findings and allowed for the consideration of other (non)believers. Overall, this study supports earlier findings on analytic atheists and SBNR while providing new information about their dispositions. Of interest, the uncertain nonbeliever group has been largely unexplored previously, and it should gain more attention in future studies.     

A practical guide to time-frequency analysis in the study of human motor behavior: the contribution of wavelet transform

The authors present a practical guide for studying nonstationary data on human motor behavior in a time-frequency representation. They explain the limits of classical methods founded exclusively on the time or frequency basis and then answer those limits with the windowed Fourier transform and the wavelet transform (WT) methods, both of which are founded on time-frequency bases. The authors stress an interest in the WT method because it permits access to the whole complexity of a signal (in terms of time, frequency, amplitude, and phase). They then show that the WT method is well suited for the analysis of the interaction between two signals, particularly in human movement studies. Finally, to demonstrate its practical applications, the authors apply the method to real data.     

A Commentary on Charles Goodwin's Co-Operative Action for Learning Scientists

ABSTRACT

This commentary summarizes the argument Charles Goodwin presents in Co-Operative Action (Co-A, 2018 Goodwin, C. (2018). Co-operative action. New York, NY: Cambridge University Press. [Google Scholar]), his most recent book. Through exploration of the breadth of conceptual and methodological tools that he has built over the course of his career and represents in this book, we suggest paths forward for Learning Sciences towards engaging in more equitable and relational research.
