Use of a statistical significance criterion in drawing inferences about hemispheric dominance for language function from dichotic listening data

A dichotic listening test (composed of VCV nonsense syllables) was administered to 31 right-handed subjects. A χ² statistical significance criterion was then applied to the resulting ear differences in subjects. Fifteen subjects had ear differences significant at the p < .10 levels. Of these, 14 had right-ear advantages, an incidence consistent with the incidence of left-hemisphere language dominance derived from neurological data. Incidence for the total group of 31 subjects, however, showed the overabundance of left-ear-superior protocols typical of studies that report ear-dominance scores with no statistical criterion.     

Organizational features of a young child's behaviors

The study was designed to investigate the nature of response-class phenomena and the possibility of indirect contingency control. A single subject was employed. Prior to the start of the study, the experimenter established the process of maintaining stimulus constancy during a preexperimental phase. Subsequent to the first baseline phase, a factor analysis was done to define the response class and the behavior categories constituting the class. Manipulating a single adult consequence to a response-class category over subsequent baseline and manipulation phases revealed frequency changes in all behavior categories in the response class. The data gave support to indirect behavior control. Search for possible explanations of frequency changes showed that the direction of the frequency changes were predictable from the results of the factor analysis.     

The effects of intrinsic and extrinsic rewards in a risk-taking situation

This study varied both the intrinsic and extrinsic rewards associated with performing a task in a risk taking situation. When the task performed to win a prize provided little if any intrinsic reward, subjects liked and tried for prizes that were easy to obtain. In contrast, when the task was intrinsically rewarding, subjects liked and tried for those prizes that were somewhat more difficult to obtain. In addition, subjects were more likely to like and try for prizes easier to obtain when the extrinsic reward was high.     

Age differences in memory span

Five-year-olds recalled fewer items than adults in memory-span tasks involving both familiar and unfamiliar faces. This occurred even though the use of rehearsal and recoding strategies was minimized for adults. This residual age difference may be partially accounted for by two further processing limitations in children. The five-year-olds needed more time than adults to name a face (Experiment 1) and to encode a face (Experiment 2). In order to test whether limitations in children's initial recognition and stimulus-identification processes could account for recall performance, Experiment 3 reduced adults' exposure duration in the memory-span task. This led to a drastic reduction in the age difference. Other factors contributing to remaining age differences included adults' adaptability in using various alternative encoding and retrieval strategies which elevated their recall performance.     

Effectiveness of Cognitive Behavioral Therapy for Anxiety and Depression Among Orthodox Jews

Several clinical papers have provided clinical recommendations for how to provide cognitive behavioral therapy (CBT) for obsessive-compulsive symptoms among Orthodox Jewish individuals. However, no published studies have described culturally adapted CBT for anxiety or depression in this population or quantified the effectiveness of such approaches. We evaluated the effectiveness of CBT for symptoms of generalized anxiety and depression in a sample of Orthodox Jews (n = 65) and a comparison sample (n = 42) presenting to the Center for Anxiety, a private outpatient clinic with three offices in the New York area (www.centerforanxiety.org). A chart review revealed that all patients received CBT-based interventions with appropriate religious-cultural adaptations of treatment, which we present in two case studies. We observed statistically and clinically significant treatment gains from pretreatment to midtreatment (anxiety: t = 8.56, p < .001; depression: t = 8.01, p < .001), and again from midtreatment through termination (anxiety: t = 3.68, p < .001; depression: t = 3.62, p < .001). No significant differences in anxiety or depression were observed between Orthodox Jewish patients and controls at any time point or for treatment effects (anxiety: Wilks’ Lambda = .950, F = 2.65, p = .076, η_p² = .050; depression: Wilks’ Lambda = .99, F = 2.00,p = .49, η_p² = .014). This paper offers clinical insight into delivery of CBT to Orthodox Jewish patients, as well as preliminary support for the effectiveness of CBT in treating symptoms of generalized anxiety and depression within this population.     

Sexual well-being and perceived stress in couples transitioning to parenthood: A dyadic analysis

Background/ObjectiveThe transition to parenthood encompasses several psychological and relational changes that might contribute to couples’ high levels of stress postpartum. Although common across the postpartum, couples’ sexual changes are frequently overlooked.MethodWe surveyed 255 mixed-sex new parent couples to examine the associations between sexual well-being—sexual satisfaction, desire, and postpartum sexual concerns—and perceived stress postpartum. Couples completed self-report questionnaires assessing perceived stress and sexual well-being.ResultsFor both mothers and fathers, greater sexual satisfaction was associated with their partners’ lower perceived stress and, for fathers, this was also associated with their own lower perceived stress. For mothers, greater partner-focused sexual desire was associated with their own lower perceived stress whereas, for fathers, greater partner-focused sexual desire was associated with their partners’ higher perceived stress. In addition, greater solitary sexual desire and postpartum sexual concerns were associated with both parents’ own higher perceived stress.ConclusionsThis study highlights the association between sexual well-being and couples’ postpartum stress, suggesting that more positive sexual experiences are linked to lower perceptions of stress across this vulnerable period. Couples’ sexual well-being may be an important target for interventions aimed at helping postpartum couples cope with stress.
