Possible effects of forced report order on tachistoscopic recognition of bilaterally presented stimuli: A response to Young and Ellis

Comparing visual field asymmetries for bilaterally presented words and corresponding line drawings, we found an RVF advantage for words and no visual field asymmetry for line drawings. We suggested that the RVF advantage previously obtained by Young, Bion, and Ellis (Brain and Language, 11, 54–65, 1980) for bilaterally presented line drawings may have resulted from a forced order of report procedure, noting that the RVF advantage was greater on trials on which subjects were forced to report in the nonpreferred right-to-left order. Young and Ellis (Brain and Language, 20, 166–171, 1983) attempt to discredit this claim and maintain their hypothesis that the RVF advantage for line drawings is attributable to better temporary storage of these stimuli by the left than the right hemisphere. In the present article, we present in greater detail our arguments for the effects of forced order of report on the perception of bilaterally presented stimuli and refute Young and Ellis's ibid. criticisms of this proposal.     

Statistical significance tests for binormal ROC curves

Statistical significance tests are derived and evaluated for measuring apparent differences between an obtained and an expected binormal ROC curve, between two independent binormal ROC curves, and among groups of independent binormal ROC curves. A binormal ROC curve is described by two parameters which represent the spread of the means and the ratio of the standard deviations of the two underlying Gaussian decision variable distributions. To test the significance of apparent differences between or among ROC curves, approximate χ² statistics for each of the three tests were constructed from maximum likelihood estimates of the two parameters defining the binormal ROC curve. The performance of each test statistic was evaluated by simulating five-category rating scale data with equal numbers of noise and signal-plus-noise trials (set at 50, 250, and 500) for each of three typical ROC curves. For the significance test involving only one ROC curve, rating scale data were generated from the chance diagonal of the ROC space also. Although test performance was found to be somewhat dependent on the number of trials and on the location of the ROC curve in the ROC space, comparisons of the obtained and expected fractions of (falsely) significant results at various α levels showed the proposed statistical significance tests to be reliable under practical experimental conditions.     

A technique for controlling speech disfluencies induced by delayed auditory feedback

On the basis of cybernetic models of speech it was hypothesized that “stuttering” induced by delayed auditory feedback could be significantly reduced if the Ss were provided with an alternate input to which they could attend. The results of the experiment supported the hypothesis. The possible implications for the treatment stuttering are discussed.     

Marital Processes Linking Gender Role Attitudes and Marital Satisfaction Among Mexican‐Origin Couples: Application of an Actor–Partner Interdependence Mediation Model

Informed by dyadic approaches and culturally informed, ecological perspectives of marriage, we applied an actor–partner interdependence mediation model (APIMeM) in a sample of 120 Mexican‐origin couples to examine (a) the associations linking Mexican immigrant husbands’ and wives’ gender role attitudes to marital satisfaction directly and indirectly through marital processes (i.e., warmth and negativity) and (b) whether the associations between spouses’ gender role attitudes and marital processes were moderated by wives’ employment. Although previous research has identified spouses’ gender role attitudes as potential predictors of spouses’ marital satisfaction, no study has examined these links in a dyadic model that elucidates how gender role attitudes may operate through processes to shape marital satisfaction and conditions under which associations may differ. We found that when spouses reported less sex‐typed attitudes, their partners reported feeling more connected to them and more satisfied with the marriage, regardless of whether wives were employed. Our results suggest that marital satisfaction was highest for those Mexican‐origin couples in which marital partners were less sex‐typed in their attitudes about marital roles to the extent that partners’ attitudinal role flexibility promoted spouses’ feelings of warmth and connection to their partner.     

Integrating Parents' Views on Sibling Relationships to Tailor an Evidence‐based Parenting Intervention for Sibling Conflict

Parents play a crucial role in the development of their children's relationships with their siblings. Despite this, relatively few evidence‐based parenting programs exist that specifically offer parents the strategies and techniques they desire and require for managing their children's sibling relationships. One way of bridging this gap is to design a tailored parenting intervention for sibling relationships that incorporates the parent voice in various aspects of program design. The current study recruited a convenience sample of 409 Australian parents to complete an online survey relating to their views on difficult sibling behaviors and what, if any, help they desire in dealing with the issue. The majority of respondents were Caucasian, middle‐ to upper‐class mothers. Respondents predominantly attributed the causes of sibling conflict to their child's internal traits, but expressed strong desire for assistance with managing behavioral problems, especially when sibling relationships were marked by physical aggression. Respondents reported high levels of acceptability for positive, rather than punitive, parenting strategies and showed a clear preference for parenting interventions delivered in easy‐to‐access formats. The findings are interpreted in the context of guiding the development of a tailored parenting intervention for enhancing sibling relationships and reducing conflict.     

Family Resource Allocation after Firstborns Leave Home: Implications for Secondborns' Academic Functioning

This study assessed secondborn adolescents' perceptions of changes in the allocation of family resources following their firstborn siblings' departure from home after high school, and whether perceived changes were related to changes over 1 year in secondborns' academic functioning. Participants were secondborn siblings (mean age = 16.58, SD = 0.91) from 115 families in which the older sibling had left the family home in the previous year. Allocation of resources was measured via coded qualitative interviews. Most (77%) secondborns reported increases in at least one type of family resource (i.e., parental companionship, attention, material goods), and many reported an increase in multiple types of resources in the year following their older sibling's departure. Consistent with resource dilution theory, perceptions of increases in fathers' companionship, fathers' attention, and mothers' companionship were related to improvements over time in secondborns' academic functioning.     

Marital Expectations in Strong African American Marriages

The current exploratory study utilized a family strengths framework to identify marital expectations in 39 strong African American heterosexual marriages. Couples reflected on their marital expectations over their 10 or more years of marriage. Three themes emerged through qualitative analysis and the participants' own words were used in the presentation of the themes. African Americans indicated that there was growth in marital expectations over time, with marital expectations often beginning with unrealistic expectations that grew into more realistic expectations as their marriages progressed. Participants also indicated that core expectations in strong African American marriages included open communication, congruent values, and positive treatment of spouse. Finally, participants explained there is an “I” in marriage as they discussed the importance of autonomy within their marital relationships. Results are discussed in association with existing research and theory.     

Child Characteristics,Parent Education and Depressive Symptoms,and Marital Conflict Predicting Trajectories of Parenting Behavior from Childhood Through Early Adolescence in Taiwan

The study examined how child and parent characteristics, and contextual sources of stress, such as marital conflict predict initial status and trajectories of parent involvement, support, and harsh control, over a 4‐year period in families in Taiwan (n = 4,754). Based on Belsky's (1984) ecological model of parenting, three domains predicting parenting were tested, child characteristics (age cohort and gender), father and mother characteristics (education and depressive symptoms), and contextual sources of stress (marital conflict). The study followed two cohorts of children; the younger cohort was followed from first to fourth grade and the older cohort from fourth to seventh grade. Initially, fourth graders reported more parental involvement, support, and harsh control than first graders. However, involvement, support, and harsh control decreased across the 4 years for the older cohort as they transitioned to early adolescence. In the first year, girls reported more parental involvement and support and less harsh control than boys. Across the 4 years, involvement and support increased, and harsh control decreased for boys; whereas involvement stayed the same, support slightly decreased, and harsh control slightly increased for girls. Children whose parents were more educated reported more parent involvement, support, and harsh control in the first year. Children whose fathers were chronically depressed and whose parents were experiencing marital conflict reported decreasing parent involvement and support over the years.
