Bilingual speech: Bilateral control?

Forty bilinguals from several language backgrounds were contrasted to a group of English-speaking monolinguals on a verbal-manual interference paradigm. For the monolinguals, concurrent finger-tapping rate during speech output tasks was disrupted only for the right hand, indicating left-hemisphere language dominance. Bilingual laterality patterns were a function of language used: native (L1) versus second acquired (L2), and age of L2 acquisition. Early bilinguals (L1 + L2 acquisition prior to age 6) revealed left-hemisphere dominance for both languages, whereas late bilinguals (L2 acquired beyond age 6) revealed left-hemisphere dominance only for L1 and symmetrical hemispheric involvement for L2.     

Linguistic recovery after closed head injury

Recovery from acute aphasia after closed head injury was studied in 21 young adults at least 6 months after injury. Three profiles of scores were found using standardized language tests. Persistent expressive and receptive impairment was present in 6 patients who sustained severe diffuse brain injury resulting in global cognitive deficit. Residual expressive impairment, primarily of naming, was associated with mild diffuse brain injury though focal left-hemisphere injury was present in 3 of 6 cases. Patients who recovered to normal levels on all language tests generally had acute neurologic findings consistent with mild diffuse brain injury. Cranial computed tomography at the time of followup frequently disclosed ventricular enlargement.     

Temporal integration and discrimination of equally detectable,equal-energy stimuli: The effect of frequency

Summary The results of several experiments are reported which indicate: 1) complete auditory temporal summation for threshold of up to 32 msec for tones of 493, 1967, and 7874 Hz using a three-alternative forced-choice technique. 2) Equal-energy, equally detectable stimuli constructed of different intensities and durations within the range of complete integration are discriminable from one another. 3) Discrimination level increases as a function of the overall energy level and, consequently, as a function of detection level. 4) When discrimination level is plotted against detection level on normal-normal coordinates, the result is a straight line with a slope (b) greater than unity (1.41b1.68). 5) The extent of the discrimination capability, as well as the slope of the function relating discrimination level to detection level, was found to be independent of the frequency of the tone.All communications regarding this paper are to be addressed to Dr Harvey Babkoff.

Encoding processes and the recall of text

Two experiments investigated the proposition that the amount of cognitive effort expended to encode information will be directly related to recall of that information. While previous research has shown that amount of processing may affect recall, these studies have generally drawn on the notion of an elaborated memory representation to explain their results. In this study, the amount of processing required to correctly interpret anaphoric relations was varied while the elaboration of the memory trace was held constant. These experiments employed a self-paced reading paradigm in which subjects read a series of short paragraphs and later were cued to recall the final sentence of each paragraph. It was found that recall was significantly improved when more processing was required to correctly interpret the anaphoric relationship expressed in the final sentence. These findings suggest that encoding processes can affect recall performance without elaboration of the memory representation.

Psychometric vs. attentional correlates of early onset alcohol and substance abuse

Adolescent inpatients with a diagnosis of alcohol abuse (n=28), nonalcohol substance abuse disorders (n=15), or psychiatric disorders without substance abuse (n=46) were examined on measures of attentional, intellectual, and personality functioning. High scores on a personality measure, the Substance Abuse Proclivity Scale (SAP), was the best predictor of substance abuse in general. Alcohol abusers were differentiated from other substance abusers by their increased impairment on the Continuous Performance Test. Adolescents with alcohol abuse did not manifest the types of cognitive impairments associated with chronic alcoholism. These data suggest that certain attentional impairments may be associated with early onset alcohol abuse and that earlier conceptions of the role of attentional impairments in risk prediction for alcohol abuse are supported.This research was supported by the Four Winds Foundation.     

Cultural Beliefs About Social Influence Strategies of Mexican Immigrant Women and Their Heterosexual Partners

The present study examined cultural beliefsregarding the use of influence strategies inheterosexual relationships of 40 Mexican immigrantcouples in stable relationships. Although over 75% ofparticipants had completed seven or more years of education,men were more likely to have completed high school thanwomen. Over half the sample (55%) reported familyincomes of $300 or less per week; 23% reported incomes in excess of $400 a week. During a structuredinterview respondents were asked to indicate their levelof agreement on a 4-point Likert scale with 24statements about influence tactics used by women and men in heterosexual relationships. Culturalconsensus analyses revealed a common cultural modelshared by the sample about which strategies men andwomen use to influence their partners. Results suggest that influence strategies are believed similarfor men and women. Direct and indirect strategies areperceived as used by both partners; bilateral strategiesare believed more likely to be used than unilateral strategies. These findings suggest that Mexicanimmigrant women in stable partnerships endorse normsthat support the use of relatively equivalent power inpartner relationships. The use of positive Mexican cultural norms to promote health protectivebehaviors such as condom use and other less risky sexualbehaviors is discussed.
