Lexical decision task performance in blood-fearful and spider-fearful individuals

University undergraduates were pre-screened for blood fearfulness (fear of blood, n = 25), spider fearfulness (fear of spiders, n = 30), or non-fearfulness (n = 23) and presented with blood, spider, neutral, positive, and pseudoword (pronouncable nonword, like flirp) stimuli in a lexical decision task (LDT). Use of the LDT in phobic individuals may provide insight about how these individuals process, store, and ultimately use information and, in turn, how processing this information affects their day-to-day activities. Words were responded to faster than pseudowords. No group main or interaction effects emerged, and all groups responded faster and more accurately to spider words then blood words and neutral words. Results suggest that the single-word lexical decision task may not be sensitive in detecting lexical processing biases toward threat in these groups. Results also suggest that paradigms that are based on high-level, semantic-conceptual information processing (like lexical decision) are not sensitive enough to detect group differences in blood and spider phobias. Any array of perceptual and conceptual tasks taken together may be needed to detect these differences.     

The Relationship Between Childhood Teasing and Later Interpersonal Functioning

The current study explored the relationship between recall of a form of bullying, specifically childhood teasing, and later interpersonal functioning in a sample of 414 college students. It was predicted that memories of frequent teasing during childhood would be associated with fewer close friends, a more anxious attachment style in the context of romantic relationships, and lower social self-esteem in early adulthood. Although recalled-teasing was not associated with number of friends later in life, it was related to other interpersonal difficulties. Specifically, frequent teasing was associated with less comfort with intimacy and closeness, less comfort in trusting and depending on others, a greater degree of worry about being unloved or abandoned in relationships, and poorer social self-esteem. The relationship of these difficulties to specific domains of teasing was also explored.

Global VOR gain adaptation during near fixation to foveal targets

Long-term rotational vestibulo-ocular (VOR) adaptation occurs during systematic dysmetria between visual and vestibular afferents, adjusting eye-rotation angular velocity to re-establish retinal stability of the visual field. Due to translational motion of the eyes during head rotation, VOR gain is higher when fixating near objects. The current study measures VOR in humans before and after 6 min of exposure to a foveal near-target during sinusoidal whole-body rotation at 0.45 Hz. All of six participants showed post-exposure increases in open-loop VOR gain after fixating near targets, demonstrating a mean modulation increase of open-loop VOR gain from 0.86 before adaptation to 1.2 after adaptation. We discuss a number of theoretical and applied implications.

Overcoming adolescents' resistance to anti-inhalant appeals.

This research was concerned with factors that affect adolescents' evaluations of persuasive anti-inhalant messages and the association of these evaluations with usage intentions. Sixth and 7th graders (N=894) received anti-inhalant messages that varied as a result of the factorial combination of message source (doctor or peer), suggested harm (social or physical), and target (message was addressed directly or indirectly to receivers). Manipulated variables were crossed with inhalant-user status (resolute nonuser, vulnerable nonuser, and user). Significant (p<.01) target and status effects on message evaluation were found. Significant interactions of status with each of the manipulated variables also emerged. Users were resistant to threatened physical harms, but suggested harms did not differentially affect resolute nonusers or vulnerable nonusers. Users and vulnerable nonusers evaluated the message more positively when targeted indirectly (p<.05). Vulnerable nonusers were more receptive to peer sources, whereas users preferred adult sources. Message evaluation was significantly associated with inhalant usage intentions (r=-.22), and this association held even after the contributions of sex, sensation seeking, acculturation, prior use, familism, and assumed peer usage were accounted for in a multiple regression analysis (overall R(2)=.24).     

Influence of expressed emotion and perceived criticism on cognitive-behavioral therapy for social phobia

This study examined significant others' expressed emotion (EE) and a closely related construct, perceived criticism, as predictors of cognitive-behavioral therapy outcome in a sample of 40 patients with social phobia (social anxiety disorder). Patients enrolled in group therapy for social phobia completed pre- and post-treatment questionnaire measures of perceived criticism and anxious and depressive symptoms. Designated significant others were assessed for the components of high EE (criticism, hostility and emotional overinvolvement) using the Camberwell Family Interview. It was hypothesized that these high-EE components and patients' perceived criticism would be associated with poorer treatment outcome, and results ran counter to these expectations. Controlling for initial social phobia severity, lower levels of perceived criticism predicted treatment dropout. There was also a nonsignificant trend for participants with a significant other rated as high in emotional overinvolvement to show less change on a composite symptom measure. Findings from this study suggest that close relationships impact the outcome of cognitive-behavioral interventions for social phobia.     

A comparison of momentary time sampling and partial-interval recording for evaluating functional relations

In the current study, momentary time sampling (MTS) and partial-interval recording (PIR) were compared to continuous-duration recording of stereotypy and to the frequency of self-injury during a treatment analysis to determine whether the recording method affected data interpretation. Five previously conducted treatment analysis data sets were analyzed by creating separate graphic displays for each measurement method (duration or frequency, MTS, and PIR). An expert panel interview and structured criterion visual inspection were used to evaluate treatment effects across measurement methods. Results showed that treatment analysis interpretations based on both discontinuous recording methods often matched those based on frequency or duration recording; however, interpretations based on MTS were slightly more likely to match those based on duration and those based on PIR were slightly more likely to match those based on frequency.     

Medicare's search for effective obesity treatments: diets are not the answer

The prevalence of obesity and its associated health problems have increased sharply in the past 2 decades. New revisions to Medicare policy will allow funding for obesity treatments of proven efficacy. The authors review studies of the long-term outcomes of calorie-restricting diets to assess whether dieting is an effective treatment for obesity. These studies show that one third to two thirds of dieters regain more weight than they lost on their diets, and these studies likely underestimate the extent to which dieting is counterproductive because of several methodological problems, all of which bias the studies toward showing successful weight loss maintenance. In addition, the studies do not provide consistent evidence that dieting results in significant health improvements, regardless of weight change. In sum, there is little support for the notion that diets lead to lasting weight loss or health benefits.
