Remembering computer command names: Effects of subject generation versus experimenter imposition

Two experiments analyzed the effectiveness of goal statements in aiding recall of self-generated as opposed to experimenter-imposed command names. Subjects were presented with a series of before-after pairs representing the computer states before and after a command was executed. In Experiment 1, during study, one group of subjects generated a command name in response to each pair; a second group generated a goal statement describing the goal to be accomplished in addition to generating a command name. During recall, half of each group was required to recall the name, whereas the other half was required to describe the goal before attempting to recall the name. In Experiment 2, during study, command names (and goals for those subjects in the goal condition) were imposed by the experimenter rather than generated by the subject. Subjects who generated goals and names recalled more command names than did those who generated only names or who received imposed goals and/or names. Generation of an appropriate goal at study improved encoding by helping subjects to select more appropriate command names; generation of an appropriate goal at test improved retrieval for appropriate names only, presumably by activating a relevant subset of names. Even in the relatively simple task of naming and remembering command names, having an appropriate model of the domain through the use of specific goal statements substantially improved performance.     

Profiles of right hemisphere language and speech following brain bisection

A variety of language tasks were administered to two patients who had undergone staged callosal section in an effort to control otherwise intractable epilepsy. Right hemisphere lexical capacity varied and preliminary results suggest that the case displaying greater semantic power also possessed some syntactic competence. This same case (V.P.) was also capable of expressive language from the right hemisphere. This rare capacity allowed for fresh observations on the dynamic interactions of conscious control that occur in this kind of patient.     

Effects of naloxone and neuroleptic drugs on muscle rigidity and heart rate of the nervous Pointer dog

Muscle rigidity, a persistent physiological characteristic of the nervous Pointer dog, is not only attenuated by the major neuroleptic drugs, haloperidol and pimozide but also by naloxone. In addition, naloxone administration results in a modest but significant increase in heart rate of these subjects. The data obtained in this study add support for the concept that an abnormality in central nervous system dopaminergic function is involved in the genesis of abnormal behavior of this animal model.     

Personality dimensions in patients with sleep-apnea syndrome: comparison with narcolepsy

Personality measures of Anxiety-Neuroticism, Extraversion and Socialization obtained from self-report questionnaires were studied in a group of sleep-apnea patients (15 males, 5 females), and compared with results from a normal control group (63 males, 21 females) and a group of narcoleptic patients (17 males, 32 females). Sleep-apnea patients were significantly higher in Anxiety-Neuroticism and slightly higher in Extraversion than controls. Although the main symptom, i.e. excessive daytime sleepiness, of sleep-apnea and narcoleptic patients is similar, there were distinct differences in pattern of personality measures. Sleep-apnea patients were lower in Anxiety-Neuroticism and higher in Extraversion. Thus, increased sleepiness alone did not induce uniform changes in personality traits in the two patient groups. It is suggested that the particular personality profile of the sleep-apnea patients is secondary to increased psychosocial strain and coping strategies to keep awake. In contrast, the high Somatic Anxiety scores and low Socialization scores in the narcoleptic group are assumed to reflect a constitutional lability which also involves autonomic and sleep functions.     

Reexamining models of healthy families

This paper presents the perceptions of members of an alternative family form concerning the strengths of their family type, the functions of family, family models, and traits of a healthy families in general. The concepts presented are the product of a qualitative research study of shared home families.     

Extradyadic romantic involvement: Moderating effects of sociosexuality and gender

The present study examined whether relationships of self-reported depression and suicidality to gender roles or gender are moderated by the type of stressful life events that individuals experience. The focus was on events in stereotypic male (achievement) versus female (interpersonal) domains. This study of 290 women and 247 men undergraduates employed the Beck Depression Inventory (BDI), the Personal Attributes Questionnaire and a measure of recent negative life events. In the presence of high achievement stress, high masculinity was related to low suicidality for men. In the presence of high interpersonal stress, high femininity was related to low self-reported depression for women. These findings were interpreted as consistent with the androgyny model of adjustment. However, independent of gender roles, high interpersonal stress was related to high self-reported depression more strongly among women than among men. Suicidality was related to interpersonal events for women and achievement events for men. These findings were interpreted as consistent with the self-schema model of depression.The authors gratefully acknowledge Jane Karyl and Ann Shields for substantial assistance with data collection and management and Michael L.
