Anxious attachment and psychological distress in cardiac rehabilitation patients

This study investigated the relevance of anxious attachment to the differentiation of psychologically distressed and non-psychologically distressed cardiac patients. Attachment is a biologically based behavioral system in which proximity to a special other is sought or maintained to achieve a sense of safety and security. Anxious attachment, as the name denotes, fails to achieve the function of attachment in the sense of individuals having little or no confidence in the availability of their attachment figures. Empirically, three scales (feared loss of the attachment figure, proximity seeking and separation protest) capture the features of anxious attachment as elaborated by Bowlby. These scales were administered to 178 cardiac rehabilitation patients drawn from the cardiac rehabilitation program of the Calgary General Hospital. The results indicate that feared loss and proximity seeking differentiated psychologically distressed from non-psychologically distressed patients. The implications of this finding for the understanding of psychologically distressed cardiac patients are discussed.     

Ability to generate mental images in students of art

To evaluate the ability to generate mental images and its relations to artistic training, 44 undergraduates were presented with a list of selected fragments from 40 characters in the Roman alphabet. Subjects provided those letters suggested by the fragments for as many items as possible within a 90-second interval. It was hypothesized that students who had received college training in studio art would be able to produce a greater number of candidate images than students not trained in art, resulting in more correct answers and higher scores. Results confirmed the hypothesis. Trained subjects completed significantly more of the letters on the image-generation task than did those not trained in art (p=.0001). This suggests that superior ability to generate images is associated with artistic training. Further, these results imply that, to the degree to which artistic training reflects ability, image generation may also be related to artistic ability.     

Vocal frequency and person perception: Effects of perceptual salience and nonverbal sensitivity

Previous research has demonstrated that changes in vocal frequency (pitch) influence judgments made about a speaker, although there is some question as to the relative importance of frequency to message content in person perception. Moreover, these studies have failed to examine the possible joint effect of frequency and individual differences in nonverbal sensitivity on person perception. The purpose of the present investigation was to examine the independent and joint effects of vocal frequency, perceptual salience, and nonverbal sensitivity (assessed by the Profile of Nonverbal Sensitivity) on person perception. Participants were assigned to one of nine experimental conditions and were asked to rate two male and two female speakers on seven unipolar adjective scales. The nine conditions were produced by factorially combining three levels each of salience (content, voice, control) and vocal frequency (decreased, increased, unmanipulated). The results of hierarchical multiple regression analyses indicated that variations in frequency did influence evaluative judgments of the speakers (competent, honest, persuasive), but that the magnitude of the influence varied as a function of the participants' levels of nonverbal sensitivity. The analyses, however, yielded no significant effects for participants' affective judgments, nor any significant effects involving perceptual salience.     

Tooth color: effects on judgments of attractiveness and age

Tooth whitening has become a very popular procedure. Advertisements for whitening products imply that whiter teeth are more attractive than yellower teeth. We tested this idea empirically by manipulating the tooth color of pictures of male and female targets. Participants' ratings of attractiveness were not influenced by tooth color. Exp. 2 yielded a negative correlation between attractiveness and age ratings: targets judged to be older were rated as less attractive. Unless whiter teeth help in some other way, e.g., improved self-esteem or confidence, it seems that tooth whitening procedures or products are not associated with increased attractiveness to others.     

Deaf readers’ response to syntactic complexity: Evidence from self-paced reading

This study was designed to determine the feasibility of using self-paced reading methods to study deaf readers and to assess how deaf readers respond to two syntactic manipulations. Three groups of participants read the test sentences: deaf readers, hearing monolingual English readers, and hearing bilingual readers whose second language was English. In Experiment 1, the participants read sentences containing subject-relative or object-relative clauses. The test sentences contained semantic information that would influence online processing outcomes (Traxler, Morris, & Seely Journal of Memory and Language 47: 69–90, 2002; Traxler, Williams, Blozis, & Morris Journal of Memory and Language 53: 204–224, 2005). All of the participant groups had greater difficulty processing sentences containing object-relative clauses. This difficulty was reduced when helpful semantic cues were present. In Experiment 2, participants read active-voice and passive-voice sentences. The sentences were processed similarly by all three groups. Comprehension accuracy was higher in hearing readers than in deaf readers. Within deaf readers, native signers read the sentences faster and comprehended them to a higher degree than did nonnative signers. These results indicate that self-paced reading is a useful method for studying sentence interpretation among deaf readers.     

A randomised controlled trial of cognitive-behaviour therapy for behavioural insomnia of childhood in school-aged children

Chronic sleep problems can lead to the development of Behavioural Insomnia of Childhood - a sleep disorder involving problematic sleep-onset associations (i.e., parental presence), and resulting in impairments for children and family members. The aim of the present paper was to perform a controlled evaluation of cognitive-behaviour therapy (CBT) for Behavioural Insomnia. 42 children (M = 9.3 ± 1.9 yrs, range 7-13 yrs, 18f, 24 m) were randomised to CBT (N = 21) or waitlist control (N = 21). CBT consisted of 6 sessions, and combined behavioural sleep medicine techniques (e.g., sleep restriction) with anxiety treatment techniques (e.g., cognitive restructuring). Compared to waitlist controls, children receiving CBT showed significant improvements in sleep latency, wake after sleep onset, and sleep efficiency (all p ≤ .003), but not total sleep time (p > .05). CBT was also associated with a reduction in problematic sleep associations (p ≤ .001), child-reported total and separation anxiety (both p ≤ .01), with all gains being maintained 6 months post-treatment. This is the first controlled study to demonstrate that multi-component CBT can be effective for the sleep, insomnia, and anxiety symptoms of Behavioural Insomnia of Childhood in school-aged children. Future research is needed to ascertain active treatment components.     

Individual difference influences on self-focused and other-focused counterproductive student behaviors

This paper extends previous research on counterproductive student behaviors by presenting an individual difference model of counterproductive student behaviors (CSBs) that includes four sets of antecedent variables: internal control variables; propensity variables; achievement striving; and severity perceptions of CSBs. Data from 276 undergraduate students shows that CSBs exhibit a two-factor solution (self-focused and other-focused CSBs), and that each of the four sets of antecedent variables explain unique variance in either self-focused CSBs or other-focused CSBs; with the influence of achievement striving being restricted to behaviors that harm the academic performance of students. The results are discussed in terms of their relationship with previous research on counterproductive behaviors and their implications for understanding of the broad domain of college student performance.     

Assessing the remedy: the case for contracts in clinical trials

Current orthodoxy in research ethics assumes that subjects of clinical trials reserve rights to withdraw at any time and without giving any reason. This view sees the right to withdraw as a simple extension of the right to refuse to participate all together. In this paper, however, I suggest that subjects should assume some responsibilities for the internal validity of the trial at consent and that these responsibilities should be captured by contract. This would allow the researcher to impose a penalty on the subject if he were to withdraw without good reason and on a whim. This proposal still leaves open the possibility of withdrawing without penalty when it is in the subject's best interests to do so. Giving researchers recourse to legal remedy may now be necessary to protect the science, as existing methods used to increase retention are inadequate for one reason or another.     

The effects of concurrent verbal and visual tasks on category learning

Current theories of category learning posit separate verbal and nonverbal learning systems. Past research suggests that the verbal system relies on verbal working memory and executive functioning and learns rule-defined categories; the nonverbal system does not rely on verbal working memory and learns non-rule-defined categories (E. M. Waldron & F. G. Ashby, 2001; D. Zeithamova & W. T. Maddox, 2006). However, relatively little research has explored the importance of visual working memory or visual processing for either system. The authors investigated the role of working memory (Experiment 1a and 1b), visual processing (Experiment 2), and executive functioning for each system, using a concurrent task methodology. It was found that visual tasks with high executive functioning demands and verbal tasks with high or low executive demands disrupted rule-defined learning, whereas any visual task, regardless of executive functioning demand, disrupted non-rule-defined learning. Taken together, these results confirm the importance of verbal working memory and executive functioning for the verbal system and provide new evidence for the importance of visual processing for the nonverbal system. These results help to clarify understanding of the nonverbal system and have implications for multiple systems theories of category learning (F. G. Ashby, L. A. Alfonso-Reese, A. U. Turken, & E. M. Waldron, 1998).     

What Influences Work-Family Conflict? The Function of Work Support and Working from Home

The current study examined how work support resources and working from home influenced forms of work-family conflict (WFC) in employees at a large corporation. Scales measuring employee’s general WFC, time-based WFC, and strain-based WFC were used to evaluate the extent to which employees experienced work-induced conflict at home. Two forms of working at home were assessed, days worked at home and extra hours worked at home, and five variables measured the extent of one’s support resources: work social support, organizational support, individual consideration from one’s manager, idealized influence from one’s manager and contingent reward from one’s manager. We predicted that days worked at home would be negatively related to the three forms of WFC, while the extra hours worked at home would be positively related. Moreover, we hypothesized that the five support variables would moderate the relationship between extra hours worked at home and the types of WFC. The data supported some of the predictions, and the implications of these findings are discussed.
