Sex differences in communication with close friends: testing Tannen's claims

In 1990 Tannen reported that men have fewer close friends than women, men discuss less intimate topics with their friends than women, and men and women respond differently to close friends' problems. 168 students completed a three-page survey designed to examine Tannen's claims. Consistent with Tannen's observations, men discussed less intimate topics (politics and school or work) with their five closest friends and reportedly were less likely to comfort or listen to their friends' problems than women were. Inconsistent with Tannen's statements, these women and men did not differ in the number of close friends they reported having or in the likelihood of offering advice when presented with a friend's problem. Present self-reports corroborate other researchers who questioned Tannen's findings and concluded that sex differences in interpersonal communication are small.     

The time course of competition for attention: attention is initially labile

Competition for attention between 2 written words was investigated by presenting the words briefly in a single stream of distractors (Experiment 1) or in different streams (Experiment 2-6), using rapid serial visual presentation at 53 ms/item. Stimulus onset asynchrony (SOA) was varied from 0 to 213 ms. At all SOAs there was strong competition, but which word was more likely to be reported shifted markedly with SOA. At SOAs in the range of 13-53 ms the second word was more likely to be reported, but at 213 ms, the advantage switched to the first word, as in the attentional blink. A 2-stage competition model of attention is proposed in which attention to a detected target is labile in Stage 1. Stage 1 ends when one target is identified, initiating a serial Stage 2 process of consolidation of that target.     

Patterns of emotion-specific appraisal,coping, and cardiovascular reactivity during an ongoing emotional episode

The authors examined emotion-specific patterns of appraisal, coping, and cardiovascular reactivity during real ongoing emotional episodes. In this study, 109 participants performed a neutral opinion-expression task, where a confederate elicited anger, shame, or pride using verbal and nonverbal behavior. The authors assessed cognitive appraisals, emotional reactions, coping, outcomes (state self-esteem and outcome satisfaction), and cardiovascular reactivity. Results indicated substantial and theoretically consistent differences between the 3 emotions (and differences from a nonemotion condition) for cognitive appraisals, self-reported coping, behavioral coping, self-esteem, and cardiovascular reactivity. The results are discussed in relation to their implications for emotion theory and for psychological and physical health. Overall, the results suggest that researchers can study emotion-related issues using authentic emotional reactions.     

Perception and production of rise-fall intonation in American English

At the segmental level, the rate of speaking affects the degree of physical undershoot of articulatory targets and the resulting perception. Little is known regarding evidence of these effects at the suprasegmental level, particularly in intonation. In this study, the effect of rate of speaking on fundamental frequency and on perceptual judgments of peak pitch in a rise-fall intonation pattern was investigated. First, speakers produced rise-fall intonations in sentence contexts at slow, normal, and fast speaking rates. Peak fundamental frequencies (F0) of the slow productions were significantly lower than those of the normal or fast productions. The mean normal rate production of the word Miami was used as a model for the target word in a series of subsequent perceptual experiments. Altering the duration of the target word to represent slow, normal, and fast rates of speaking did not affect listener judgment of peak pitch. Finally, the pitch of the target word was measured in a sentence context. No differences between peak pitch in isolation or in sentence context were found. It was concluded that the production and perception of this form of intonation was not subject to the effects of rate that are seen at the segmental level.     

Exposure to violence and suicide risk in adolescents: a community study

The prevalence of violence exposure is relatively unexplored in adolescents in European communities, and reports on the association between exposure to community violence and suicidal behavior are rare. The aim of this study was to investigate (1) the prevalence of community violence in a European urban adolescent sample, (2) the relationship between exposure to community violence and suicidal ideation/deliberate self-harm, and (3) the influence of depressive symptoms and aggressive behavior on this relationship. Self-report surveys were administered to a representative school-based sample of 1509 adolescents in Antwerp (Belgium). The prevalence rate of violence exposure was still high but lower than that reported in U.S. communities. Suicidal ideation and deliberate self-harm were both related to violence exposure. The gender-specific influence of depressive symptomatology and aggressive behavior on the association between exposure to violence and suicidal behavior suggests the need for further research.     

Inter-rater and test-retest reliability of the Revised Diagnostic Interview for Borderlines

The baseline inter-rater reliability, test-retest reliability, follow-up inter-rater reliability, and follow-up longitudinal reliability (interrater reliability between generations of raters) of borderline symptoms and the diagnosis of borderline personality disorder (BPD) were assessed using the Revised Diagnostic Interview for Borderlines (DIB-R). Excellent kappa s (> .75) were found in each of these reliability substudies for the diagnosis of BPD itself. Excellent kappa s were also found in each of the three inter-rater reliability substudies for the vast majority of borderline symptoms assessed by the DIB-R. Test-retest reliability for these symptoms was somewhat lower but still very good. More specifically, one-third of the BPD symptoms assessed had a kappa in the excellent range and the remaining two-thirds had a kappa in the fair-good range (.57-.73). The dimensional reliability of BPD symptom areas was somewhat higher than for categorical measures of the subsyndromal phenomenology of BPD. More specifically, all five dimensional measures of borderline psychopathology had intraclass correlation coefficients in the excellent range for all four reliability substudies. Taken together, the results of this study suggest that both the borderline diagnosis and the symptoms of BPD can be diagnosed reliably when using the DIB-R. They also suggest that excellent reliability, once achieved, can be maintained over time for both the syndromal and subsyndromal phenomenology of BPD.     

Extraretinal and retinal amplitude and phase errors during Filehne illusion and path perception

Pursuit eye movements give rise to retinal motion. To judge stimulus motion relative to the head, the visual system must correct for the eye movement by using an extraretinal, eye-velocity signal. Such correction is important in a variety of motion estimation tasks including judgments of object motion relative to the head and judgments of self-motion direction from optic flow. The Filehne illusion (where a stationary object appears to move opposite to the pursuit) results from a mismatch between retinal and extraretinal speed estimates. A mismatch in timing could also exist. Speed and timing errors were investigated using sinusoidal pursuit eye movements. We describe a new illusion--the slalom illusion--in which the perceived direction of self-motion oscillates left and right when the eyes move sinusoidally. A linear model is presented that determines the gain ratio and phase difference of extraretinal and retinal signals accompanying the Filehne and slalom illusions. The speed mismatch and timing differences were measured in the Filehne and self-motion situations using a motion-nulling procedure. Timing errors were very small for the Filehne and slalom illusions. However, the ratios of extraretinal to retinal gain were consistently less than 1, so both illusions are the consequence of a mismatch between estimates of retinal and extraretinal speed. The relevance of the results for recovering the direction of self-motion during pursuit eye movements is discussed.     

Effects of Stimulant Medication Treatment on Mothers' and Children's Attributions for the Behavior of Children with Attention Deficit Hyperactivity Disorder

Participants were 55 children with attention deficit hyperactivity disorder (ADHD) who were receiving ongoing treatment with stimulant medications and their mothers, and 31 children with ADHD who were beginning stimulant medication and their mothers. Mothers and children offered attributions for child behaviors that occurred when the child was medicated and not medicated. Mothers rated child compliance and prosocial behavior as more global and stable when the child was medicated and rated noncompliance, ADHD symptoms, and oppositional behavior as more externally caused, less global and stable, but more controllable by the child when the child was medicated. Children rated both their compliance and noncompliance as more controllable in the medicated condition. On a forced-choice measure, both mothers and children selected ability, effort, and task attributions for compliance more in the not-medicated condition, and pill-taking attributions more in the medicated condition. This was reversed for noncompliance, which was attributed more to effort, task, or ability in the medicated condition and more to not taking a pill in the not-medicated condition. The potential risks and benefits for parent–child interactions and children's self-perceptions of these medication-related differences in attributions are discussed.     

Positive behavior support: Expanding the application of applied behavior analysis

Positive behavior support (PBS) is an approach to providing services to individuals who exhibit challenging behavior. Since its inception in the early 1990s, PBS has received increasing attention from the behavior-analytic community. Some behavior analysts have embraced this approach, but others have voiced questions and concerns. In this paper we describe the framework of PBS and show that it is consistent with the tenets of behavior analysis. Also, we illustrate how the framework of PBS might be used to guide practitioners and researchers in the field of applied behavior analysis. We hope to demonstrate that PBS offers useful suggestions regarding how applied behavior analysts can design and evaluate effective programs for people with developmental disabilities or behavioral challenges.     

A short duration group treatment of smoking behavior by stimulus saturation

Two saturation procedures of different lengths were administered to Ss who desired to quit smoking. Ss chain-smoked for either 20 hr (group E₁) or 10 hr (E₂). Total abstinence was the main dependent measure. Both groups experienced relatively equal success on a short-term basis. Long-term abstinence was noted for group E₁ only. Sixty per cent of the E₁ Ss were not smoking 4 months after treatment.
