Are generic predictions enough?

Summary and conclusions I have argued not that economics has no predictive content, but that it is limited, or at least has so far been limited to generic predictions. Now this is an important kind of prediction, and almost certainly a necessary preliminary to specific or quantitative predictions. But if the sketch of an important episode in the twentieth century history of the subject I have given is both correct and representative, then economics seems pretty well stuck at the level of generic prediction. And at least some influential economists and philosophers of economics seem well satisfied with stopping at the point of generic prediction. Or at least they give no other reason than its power to produce such predictions as a justification for the character of economic theory. But this leads to the question that is the title of my paper, is generic prediction enough?     

Gender attitudes in children

This study investigated children's gender attitudes as a function of the sex, age, and race of the child as well as a geographical SES factor. Two attitudes were measured: gender pride (attributing positive characteristics to a child of the same sex) and gender prejudice (attributing negative characteristics to a child of the other sex). Results indicated that all children tended to select children of the same sex for the positive attributes, but that both boys and girls selected boys for the negative attributes. Although all sex pride scores decreased with age, this effect was most pronounced for girls from an upper-lower-class urban environment.The write-up of this article was supported by our current National Institute of Mental Health Grant No. 1R01MH29417-01, Principal Investigator, Dr. Phyllis A.

Acoustic feature analysis in the perception of voicing contrasts

Various types of acoustic cues have been shown to signal voicing contrasts in initial prestressed stop consonants. Two of the most important of these cues are the time interval between the release burst and the onset of voicing (voice onset time) and the duration of voiced transitions. In the present experiment, a selective adaptation procedure was used to investigate possible feature extraction mechanisms which underlie the perception of voicing. Subjects first identified either of two series of test stimuli, [ba-p^ha) or [ga-k^ha]. Next they listened to repeated presentations of an adapting stimulus and then again identified the original test series. Adapting stimuli having the same value of voice onset time but different voiced transition durations produced differential (and sometimes opposite) effects on the identification of the test stimuli. In every case, the adapting stimulus with the greater duration of voiced transitions led to larger reduction in voiced responses or to a smaller increase in voiceless responses. These results are incompatible with models of voicing perception based strictly on detectors for voice onset time. The results also suggest that the adaptation effect occurs at a point in the system prior to the actual phonetic decision.     

Linkages between facial expressions of anger and transient myocardial ischemia in men with coronary artery disease

The authors examined whether facial expressions of emotion would predict changes in heart function. One hundred fifteen male patients with coronary artery disease underwent the Type A Structured Interview, during which time measures of transient myocardial ischemia (wall motion abnormality and left ventricular ejection fraction) were obtained. Facial behavior exhibited during the ischemia measurement period was videotaped and later coded by using the Facial Action Coding System (P. Ekman & W. V. Friesen, 1978). Those participants who exhibited ischemia showed significantly more anger expressions and nonenjoyment smiles than nonischemics. Cook-Medley Hostility scores did not vary with ischemic status. The findings have implications for understanding how anger and hostility differentially influence coronary heart disease risk.     

Brain hyper‐connectivity and operation‐specific deficits during arithmetic problem solving in children with developmental dyscalculia

Developmental dyscalculia (DD) is marked by specific deficits in processing numerical and mathematical information despite normal intelligence (IQ) and reading ability. We examined how brain circuits used by young children with DD to solve simple addition and subtraction problems differ from those used by typically developing (TD) children who were matched on age, IQ, reading ability, and working memory. Children with DD were slower and less accurate during problem solving than TD children, and were especially impaired on their ability to solve subtraction problems. Children with DD showed significantly greater activity in multiple parietal, occipito‐temporal and prefrontal cortex regions while solving addition and subtraction problems. Despite poorer performance during subtraction, children with DD showed greater activity in multiple intra‐parietal sulcus (IPS) and superior parietal lobule subdivisions in the dorsal posterior parietal cortex as well as fusiform gyrus in the ventral occipito‐temporal cortex. Critically, effective connectivity analyses revealed hyper‐connectivity, rather than reduced connectivity, between the IPS and multiple brain systems including the lateral fronto‐parietal and default mode networks in children with DD during both addition and subtraction. These findings suggest the IPS and its functional circuits are a major locus of dysfunction during both addition and subtraction problem solving in DD, and that inappropriate task modulation and hyper‐connectivity, rather than under‐engagement and under‐connectivity, are the neural mechanisms underlying problem solving difficulties in children with DD. We discuss our findings in the broader context of multiple levels of analysis and performance issues inherent in neuroimaging studies of typical and atypical development.

Crossing the cultural divide: issues in translation, mistrust, and cocreation of meaning in cross-cultural therapeutic assessment

This article examines cross-cultural therapeutic assessment in a community mental health clinic. The first case describes the work between a Caucasian assessor and a Mexican American family. The authors explore the metaphorical and literal translation of the findings from English to Spanish and the parallel process of translation of the self, experienced by both assessor and client. The second case describes the work between a Caucasian assessor and an African American adolescent. We describe the inherent challenge between the Eurocentric "task" orientation of the evaluation and the Afrocentric "relationship" orientation. We suggest that bridging the gap between cultures and overcoming cultural mistrust lay in the building of the assessor-client relationship. Fischer's concepts of rapport and intimacy are emphasized and expanded on as we emphasize the importance of cocreated meaning in cross-cultural assessment work.
