Rapid automatized naming in children referred for evaluation of heterogeneous learning problems: how specific are naming speed deficits to reading disability?

Because the Rapid Automatized Naming (RAN) test reliably predicts reading skill, it is typically viewed as a diagnostic indicator of risk for reading disability (RD). Since most of the work on naming speed has been undertaken within the framework of reading research, however, the extent to which poor RAN is specifically associated with RD or with learning impairment (LI) in general is uncertain. We tested the hypothesis that slow naming speed is specific to RD. Participants were 188 children (ages 7 to 11) referred for evaluation of learning problems. Receiver operating characteristic (ROC) analysis was used to evaluate the utility of the RAN task for classifying children in diagnostic groups. RAN was an excellent tool for detecting risk for learning problems in general, but it was much less effective at distinguishing LI children with and without RD from each other.     

Traumatische Trauer – ein eigenständiges Krankheitsbild?

Grief is a highly individualized process influenced by intrapsychic, interpersonal and social factors. The definition of normal and pathological grief is complicated by the variety of grief reactions. Empirical research indicates that pathological grief may be concerned considered as a separate entity. Two research groups developed empirically validated criteria with a special focus on the traumatic aspect of grief. The current state of research allows, however, in our opinion not the conclusion, that the proposed diagnostic criteria for complicated (Horowitz et al. 1997) or traumatic grief (Prigerson et al. 1999b) do not enclose all types of grief. Further empirical research on representative samples is necessary to validate previous findings and to differentiate specific subgroups of pathological grief.     

Strength of German accent under altered auditory feedback

Borden’s (1979, 1980) hypothesis that speakers with vulnerable speech systems rely more heavily on feedback monitoring than do speakers with less vulnerable systems was investigated. The second language (L2) of a speaker is vulnerable, in comparison with the native language, so alteration to feedback should have a detrimental effect on it, according to this hypothesis. Here, we specifically examined whether altered auditory feedback has an effect on accent strength when speakers speak L2. There were three stages in the experiment. First, 6 German speakers who were fluent in English (their L2) were recorded under six conditions—normal listening, amplified voice level, voice shifted in frequency, delayed auditory feedback, and slowed and accelerated speech rate conditions. Second, judges were trained to rate accent strength. Training was assessed by whether it was successful in separating German speakers speaking English from native English speakers, also speaking English. In the final stage, the judges ranked recordings of each speaker from the first stage as to increasing strength of German accent. The results show that accents were more pronounced under frequency-shifted and delayed auditory feedback conditions than under normal or amplified feedback conditions. Control tests were done to ensure that listeners were judging accent, rather than fluency changes caused by altered auditory feedback. The findings are discussed in terms of Borden’s hypothesis and other accounts about why altered auditory feedback disrupts speech control.

Situational Determinants of the Acceptability of Telling Lies1

It was tested whether the same factors people take into account when involved in the decision to lie apply to the evaluation of lies presented in scenarios. The scenarios represented 12 different situation categories formed by the crossing of the motive for lying (social. individualistic, egoistic), the relative importance of the situation (important matter, unimportant matter), and the closeness of the relation between the subject and the receiver of the lie (best friend, acquaintance). The acceptability of lying was evaluated from 2 perspectives (self, others) by 180 women of the general public. The results show that as the interest of the person that is lied to becomes greater, lying becomes more acceptable. As the interest of the liar becomes greater, lying becomes less acceptable. The systematically higher estimations of acceptability attributed to others indicate a false-uniqueness effect.     

Single and multidimensional same-different judgments

A probabilistic, multidimensional Thurstonian model for treating same-different judgments was tested in an experiment in which subjects made single-dimensional and two-dimensional same-different judgments. Strong asymmetries in the data required adding temporal bias parameters to the model. The model, with bias parameters, accounted for the single- and two-dimensional judgments reasonably well, but the parameters were not invariant between the different solutions. The two-dimensional judgments were more variable than expected on the basis of the single-dimensional judgments.
