Telling stories: metaphors of the Human Genome Project

Scientists of the Human Genome Project tend to rely on three metaphors to describe their work, each of which implicitly tells much the same story. Whether they claim to interpret the ultimate “book,” to fix a flawed “machine,” or to map a mysterious “wilderness,” they invariably cast the researcher as one who dominates and exploits the Other. This essay, which explores the ways such a story conflicts with feminist values, proposes an alternative.     

Marital attributions in spouses of depressed patients

Causal attributions (i.e., locus, stability, globality) and responsibility attributions (i.e., bad intent, selfish motivation, blame) were assessed in the spouses of 27 depressed psychiatric inpatients and 30 nondepressed dyads to test predictions derived from Hooley's (1987) symptom-controllability model of marital distress. Results indicated that (1) depressed patients and their spouses were less dyadically adjusted than nondepressed spouses, (2) causal and responsibility attributions about depressive behaviors predicted lower dyadic adjustment, and (3) attributions of causality mediated the relationship between group status (depressed or nondepressed) and dyadic adjustment among spouses who had higher expectations for their partner to change. Results suggest that among spouses with a high expectancy for change, depression may be a risk factor for marital distress.     

PHONOLOGICAL CODES ARE AUTOMATICALLY ACTIVATED DURING READING:

Abstract— Subjects read sentences containing target words that were homophones (words with a single pronunciation but different spellings) while their eye movements were recorded A prime word was presented briefly at the onset of fixation on the target region The prime for a given target (e g, beach) was either identical to the target (beach, a phonologically similar word (the homophone beech), a visually similar nonhomophone (bench), or a dissimilar word (noise) Phonological priming effects were assessed by comparing fixation times on the target when It was preceded by the homophone versus the visually similar word Results suggest that phonological codes are automatically activated during eye fixations in reading     

MOTHERS' ALCOHOL CONSUMPTION DURING PREGNANCY:

Abstract— Fourteen-year-old adolescents' behavior on a spatial-visual reasoning task was associated with self-report of their mothers' alcohol consumption during pregnancy, IS years earlier The task was arranged so that it was possible to evaluate the examinees' tendency to respond rapidly and less accurately, or slowly and more accurately The greater the mother's reported drinking, the faster and less accurately the adolescent responded The decrement in visual-spatial reasoning related to alcohol appears to be linked to a tendency toward impulsive responding     

Dissociating the generation stage in implicit and explicit memory tests: Incidental production can differ from strategic access

An assumption of the generate/recognize model of direct and indirect memory is that the generation stage is identical on explicit and implicit tests. Two experiments were conducted to examine the generation stage by requiring subjects to write down every word-stem solution they could generate on either an implicit test, a cued-recall test, or a generate/recognize test. In Experiment 1, the subjects studied words and anagrams; target generation was not significantly different on the three tests. However, in Experiment 2, the subjects studied the target words with a context word, and saw either thesame ordifferent context with the test stem. Now the generation stages dissociated, such that the context manipulation had no significant effect on the implicit test, but on the cued-recall test, more targets were generated with the same context words than were generated with different context words. The results argue against the claim that dissociations between implicit and explicit tests are due only to the addition of recognition processes on the explicit test, because the generation processes themselves can be dissociated.     

The advantage of first mention in Spanish

An advantage of first mention—that is, faster access to participants mentioned first in a sentence—has previously been demonstrated only in English. We report three experiments demonstrating that the advantage of first mention occurs also in Spanish sentences, regardless of whether the first-mentioned participants are syntactic subjects, and regardless, too, of whether they are proper names or inanimate objects. Because greater word-order flexibility is allowed in Spanish than in English (e.g., nonpassive object-verb-subject constructions exist in Spanish), these findings provide additional evidence that the advantage of first mention is a general cognitive phenomenon.     

Vibrotactile pattern discrimination and communality at several body sites

In a series of experiments, the effects of spatial layout on vibrotactile pattern perception were explored by testing the ability to discriminate between two sequentially presented patterns that share active elements in the same spatial locations. Two-dimensional displays were used in order to examine the functional relationship between discrimination performance and patterncommunality, defined as the sharing elements, on different body sites. Accuracy of discrimination judgments was inversely proportional to communality, regardless of the number of pattern elements. For compact arrays fitted to the finger, palm, and thigh, the effects of communality appeared equivalent. The similarity between finger and thigh functions is remarkable, considering the dramatic differences between these sites in receptor components and structure. When these data were compared with those from arrays with distributed contactors, performance was substantially better with well-separated pattern elements. Such findings help to explicate how information from apposed patterns can best be delivered to the skin through tactile communication systems.     

The Fire Chief microworld generating program: An illustration of computer-simulated microworlds as an experimental paradigm for studying complex decision-making behavior

Computer-simulated microworlds bridge the gap between the complexity of field investigations and the rigor of laboratory studies. The purpose of this paper is to draw attention to the major methodological issues involved in developing and using computer-simulated microworlds for the psychological study of complex decision-making behavior. These issues comprise flexibility and generality in the microworlds that can be created, adequate psychological validity, automatic trial administration and data logging, capacity to interface simulations of psychological processes, and adequate testing and documentation. Each of these issues is illustrated by indicating how it has been addressed in Fire Chief, a microworld generating program specifically designed for creating realistic, yet controllable, decision-making task environments in the psychology laboratory. Fire Chief (Omodei & Wearing, 1993a) is introduced as both fully portable to other research teams and suitable for use in many different contexts requiring a complex task situation.     

Individual differences in preschoolers' physiological and verbal responses to videotaped angry interactions

Individual differences in selection of intensity of angry interactions and physiological and self-reported responses to interadult anger were examined in preschoolers (N=34). Children watched two videotaped angry interactions between adults, while their heart rates and skin conductance responses and levels were monitored; then they were interviewed. Before the second argument, children were given the perceived choice of watching an intense or mild angry exchange. Individual differences in responding to the angry interactions were found. Both (a) children with relatively higher externalizing behavior problems and (b) boys who chose to watch intense anger had lower tonic heart rates; 80% of boys with externalizing problems chose to watch intense anger. Further, children who chose to watch intense anger (a) exhibited lower declines in heart rates upon the presentation of the argument, (b) perceived the actors as more angry, and (c) reported lower amounts of distress during the argument than those who chose mild anger.     

An observation of gender-specific teacher behavior in the ESL classroom

For the most part, gender-differentiated teacher behavior in English as a Second Language classrooms in the United States has not been examined. Does the preference for male students demonstrated by both male and female teachers in American classrooms (Sadker et. al., 1992) also occur in ESL classrooms? If so, are ESL teachers aware they show such bias? To find out, the author observed and evaluated, both quantitatively and qualitatively, classroom interactions of four ESL teachers. The teachers, two males and two females, were white, American-born, and had finished graduate studies. All but one of the ESL teachers observed showed remarkable equality in their classroom interactions with the genders. The results are discussed, and future research directions proposed.
