Conversational time patterns and mutual influence in parent-child interactions: A time series approach

Mutual influencing processes are assumed to be the basic building blocks in establishing parentchild bonding and in influencing cognitive and language behavior. A study by Jasnow and Feldstein (1986) revealed that, within the temporal domain of speech, preverbal (9-month-old) infants and their mothers exhibit a pattern of mutual influence (attunement) in their average durations of switching pauses. The general purpose of this research was to extend those findings to children with higher verbal functioning. In addition, parent and child genders, nature of the interaction, and specific aspects of parents' personalities, expressiveness, and instrumentality were considered. Each parent interacted with their 4-or 5-year-old son or daughter in each of two conversations—unstructured (social conversation) and structured (task activity). Conversations were processed by an automated computer system yielding objective measure of turns, vocalizations, pauses, and switching-pause durations. To examine interspeaker influence or attunement of temporal speech patterns, influence coefficients were computer for each speaker on a turn-by-turn basis using time series regression. Analysis of these coefficients revealed that: (1) Mutual influence is most evident with switching-pause duration. (2) Structure in the conversation (as defined by the task or parental instrumentality) seems to facilitate attunement for vocalization and switching pause duration. (3) Attunement with girls seems to occur equally well with both parents, while boys exhibit a style of temporal patterning influence which suggests greater identification with the father. (4) Expressiveness seems to facilitate attunement to the child's switching-pause duration.     

A multidimensional scaling analysis of vowel discrimination in humans and monkeys

Multidimensional scaling (MDS) was used to compare perceptual maps for 10 synthetic English vowels in humans and Old World monkeys (Macaca fuscata andCercopithecus albogularis). Subjects discriminated among the vowels using a repeating background procedure, and reaction times were submitted to an MDS analysis to derive measures of perceived similarity. The dimensions that emerged related to the frequencies of the first(F1), second(F2), and third(F3) formants. Human data indicated a good match to previous MDS studies using rating procedures or confusion matrices: The dominant dimension mapped onto vowelF2, the phonetically most important formant, and the second and third dimensions mapped ontoF1 andF3, respectively.For monkeys, equal weightings occurred forF1 andF2, andF3 was not clearly represented. Monkey sensitivity to the formants appeared to relate to formant amplitudes. If monkeys are giving an accurate representation of the psychoacoustic relations among the formants, then our human results suggest that species-specific mechanisms, reflecting the salience of the phonetic feature of advancement, may contribute to vowel coding in humans.     

“My big sister the town supervisor”: Family leadership training is not just for boys

This study investigates gender similarity in the effects of birth order upon political leadership. Town supervisors were the leaders studied as there are a considerable number of women who attain this level of leadership. Questionnaires about birth order and family size were gained from 66 women who were town supervisors in New York State in 1992, and compared to a randomly selected sample of 57 male town supervisors. It was found that women as well as men town supervisors were more likely to have been first born in their families. However, whereas gender does not apparently influence the relevance of birth order for leadership, it clearly does exert an influence on the level of political leadership attained. Women town supervisors gained their positions in towns that were considerably smaller than the towns led by the male supervisors. Discussion concerned the nature of family experiences that contribute to leadership training, including those that may be different for girls and boys. Further research is needed to clarify barriers to female assertion of political leadership at more senior levels, because as this study shows, female leadership is being trained in families.     

Mindless reading: Eye-movement characteristics are similar in scanning letter strings and reading texts

The purpose of the present study was to compare the oculomotor behavior of readers scanning meaningful and meaningless materials. Four conditions were used—a normal-text-reading control condition, and three experimental conditions in which the amount of linguistic processing was reduced, either by presenting the subjects with repeated letter strings or by asking the subjects to search for a target letter in texts or letter strings. The results show that global eye-movement characteristics (such as saccade size and fixation duration), as well as local characteristics (such as word-skipping rate, landing site, refixation probability, and refixation position), are very similar in the four conditions. The finding that the eyes are capable of generating an autonomous oculomotor scanning strategy in the absence of any linguistic information to process argues in favor of the idea that such predetermined oculomotor strategies might be an important determinant of eye movements in reading.     

MENSTRUAL JOY The Construct and Its Consequences

Fifty female college students participated in a study of women's health. In a counterbalanced design, half of the participants completed the Menstrual Joy Questionnaire (MJQ) and the Menstrual Attitude Questionnaire (MAQ) in the first testing session. A week later they completed the Menstrual Distress Questionnaire (MDQ) and the Menstrual Attitude Questionnaire. The other participants completed the MDQ and MAQ in the first session and the MJQ and MAQ in the second. A multivariate analysis of variance revealed that those who received the MJQ first reported more positive cyclic changes on the MDQ and more positive attitudes on the MAQ. A follow-up study of 40 college students examined their responses to the MJQ. Participants reported that they were surprised or incredulous; most had not previously considered positive aspects of the menstrual cycle. Thirty percent reported that the MJQ had caused them to look at menstruation in a different way.     

Memory trace development along a coarse-to-fine dimension; a study supporting a progressively finer attributes theory

This study presents two experiments that demonstrate that the memory trace of a tobe-remembered item develops along a dimension (continuum) from coarse/general to fine/specific. Similarly, forgetting is shown to be a reverse movement along this dimension from fine to coarse, as increasingly less fine attributes are lost. The attribute acquisition pattern of this Progressively Finer Attributes Theory is robust and predictable, valid for experimentally unstructured (Experiment 2) as well as experimentally structured (Experiment 1) material.     

The development of beliefs about spelling and their relationship to spelling performance

This study examined relations among spelling performance and students' beliefs about spelling, including self-efficacy for spelling ability, outcome expectancy for spelling, and attributions for good spelling across grades 4, 7, and 10. Spelling self-efficacy remained relatively constant across grades. Spelling outcome expectancies for adult life and school declined across grades, as did effort and ability attributions for spelling success, with a disproportional decrease in ability attributions between grades 4 and 7. Self-efficacy was the strongest predictor of spelling performance at all grade levels; attribution for ability entered into the regression for grade 4 students, while outcome expectancies for school and writing were more important in grades 7 and 10. Cluster analyses on the grade 10 sample showed that students with high efficacy as spellers and high outcome expectancy of spelling for writing were the best spellers, with the highest performance reserved for those who attributed good spelling more to effort than ability. The impact of spelling instruction on developing beliefs is discussed.     

Issues presented by mandatory reporting requirements to researchers of child abuse and neglect

Mandatory reporting laws, which vary slightly from state to state, require reporting by helping professionals when there is reasonable cause to suspect child abuse. Institutional Review Boards (IRBs) require researchers to warn subjects of this duty to report, which may have a chilling effect on subject rapport and candor. Certificates of confidentiality, in conjunction with other precautions, may reduce some barriers to valid research. Attempts to resolve problems created by reporting laws must produce the most valid research, while minimizing harm and distress to research participants, their families, and the researcher and meeting local and federal legal requirements.     

A NINETEENTH-CENTURY IRASian: SARAH ALDEN BRADFORD RIPLEY

Abstract. Almost entirely self-educated, Sarah Alden Bradford Ripley (1793–1867) combined wide-ranging personal studies with the daily responsibilities of a New England minister's wife, mother, and teacher in her husband's boarding school. As she struggled to reconcile the conventional Unitarian Christian beliefs of her time with her own life experience and with the discoveries of advancing science, her childhood faith gave way to skepticism. Gradually she was able to integrate her understanding of nature, science, philosophy, and religion into a mature faith. She would have welcomed the companionship and support of IRAS if it had existed in her day.
