Discrete emotions and persuasion: the role of emotion-induced expectancies

The authors argue that specific emotions can alter the persuasive impact of messages as a function of the emotional framing of persuasive appeals. Because specific emotions inflate expectancies for events possessing matching emotional overtones (D. DeSteno, R. E. Petty, D. T. Wegener, & D. D. Rucker, 2000), the authors predicted that attempts at persuasion would be more successful when messages were framed with emotional overtones matching the emotional state of the receiver and that these changes would be mediated by emotion-induced biases involving expectancies attached to arguments contained in the messages. Two studies manipulating discrete negative emotional states and message frames (i.e., sadness and anger) confirmed these predictions. The functioning of this emotion-matching bias in parallel with emotion-induced processing differences and the limitations of a valence-based approach to the study of attitude change are also considered.     

VIZ: The visualization assessment and training Web site

The VIZ Website(http:/viz.bd.psu.ech]/viz/) was developed as a free and open portal for assessment and training of spatial skills. Using Macromedia Authorware, it allows the collection of response times and accuracies from four spatial tasks: mental rotation, paper folding, water level judgments, and spatial working memory. Additional tasks are under development. The site has been used for a variety of teaching and research purposes. For example, incoming engineering students have completed the tasks to assess their spatial skills before beginning their graphics courses. Those with poorer skills can then receive the appropriate remedial instruction. The VIZ site has also been used to teach about spatial cognition and to do research outside the laboratory setting. Finally, we are using the site to conduct basic research on spatial cognition, including an examination of the factors that may reduce gender differences in performance.     

An evidential support accumulation model of subjective probability

A model of cue-based probability judgment is developed within the framework of support theory. Cue diagnosticity is evaluated from experience as represented by error-free frequency counts. When presented with a pattern of cues, the diagnostic implications of each cue are assessed independently and then summed to arrive at an assessment of the support for a hypothesis, with greater weight placed on present than on absent cues. The model can also accommodate adjustment of support in light of the baserate or prior probability of a hypothesis. Support for alternatives packed together in a "residual" hypothesis is discounted; fewer cues are consulted in assessing support for alternatives as support for the focal hypothesis increases. Results of fitting this and several alternative models to data from four new multiple-cue probability learning experiments are reported.     

Picture interpretation and Jungian typology

This study examined a Jungian picture interpretation schema, which utilizes a specific quadrant method. This proposed schema, which is used in training at the C. G. Jung Institute in Zürich, attaches significance to specific areas of a drawing. The upper left of a drawing is associated with the father; the lower left with the unconscious; the lower right with the mother; and the upper right with the future. Three questions served as the foci of this study: Is the schema valid? Do certain types within Jung's personality theory respond better than others to the schema? Does the schema work best when it elicits a strong affective response from the person who created the picture? Subjects took one of two tests: a space domain test, or a colour associative test. The results revealed only two significant effects: a positive association (in the space domain test) between unconscious material with the unconscious quadrant and a negative association (in the colour associative test) of mother material with the mother quadrant. These results suggest that the Jungian quadrant schema used to interpret drawings is invalid and of minimal practical utility. Other methods of picture interpretation are discussed as well as suggestions for future research that would be helpful to this field.     

When parallel processing in visual word recognition is not enough: new evidence from naming

Low-frequency irregular words are named more slowly and are more error prone than low-frequency regular words (the regularity effect). Rastle and Coltheart (1999) reported that this irregularity cost is modulated by the serial position of the irregular grapheme-phoneme correspondence, such that words with early irregularities exhibit a larger cost than words with late ones. They argued that these data implicate rule-based serial processing, and they also reported a successful simulation with a model that has a rule-based serial component—the DRC model of reading aloud (Coltheart, Rastle, Perry, Langdon, & Ziegler, 2001). However, Zorzi (2000) also simulated these data with a model that operates solely in parallel. Furthermore, Kwantes and Mewhort (1999) simulated these data with a serial processing model that has no rules for converting orthography to phonology. The human data reported by Rastle and Coltheart therefore neither require a serial processing account, nor successfully discriminate among a number of computational models of reading aloud. New data are presented wherein an interaction between the effects of regularity and serial position of irregularity is again reported for human readers. The DRC model simulated this interaction; no other implemented computational model does so. The present results are thus consistent with rule-based serial processing in reading aloud.     

Predictors of Self-Reported Anxiety and Panic Symptoms: An Evaluation of Anxiety Sensitivity, Suffocation Fear, Heart-Focused Anxiety, and Breath-Holding Duration

The purpose of this study was to examine the extent to which anxiety-related individual difference variables predict anxious responding when individuals experience aversive bodily sensations. Thus, we explore several psychological and behavioral predictors of response to a single 25-sec inhalation of 20% carbon dioxide-enriched air in 70 nonclinical participants. Predictor variables included anxiety sensitivity, suffocation fear, heart-focused anxiety, and breath-holding duration. Multiple regression analyses indicated that only anxiety sensitivity significantly predicted postchallenge panic symptoms, whereas both anxiety sensitivity and suffocation fear predicted postchallenge anxiety. These data are in accord with current models of panic disorder that emphasize the role of fear of fear in producing heightened anxiety and panic symptoms and help clarify specific predictors of anxiety-related responding to biological challenge.     

Controlling for Prior Attainment Reduces the Positive Influence that Single-Gender Classroom Initiatives Exert on High School Students’ Scholastic Achievements

Research points to the positive impact that gender-segregated schooling and classroom initiatives exert on academic attainment. An evaluation of these studies which reveal positive effects highlights, however, that students are typically selectively assigned to single- or mixed-gender instructional settings, presenting a methodological confound. The current study controls for students’ prior attainment to appraise the efficacy of a single-gender classroom initiative implemented in a co-educational high school in the United Kingdom. Secondary data analysis (using archived data) was performed on 266 middle-ability, 11–12 year-old students’ standardized test scores in Languages (English, foreign language), STEM-related (Mathematics, Science, Information and Communication Technology), and Non-STEM subjects (art, music, drama). Ninety-eight students (54, 55% female) were taught in single-gender and 168 (69, 41% female) in mixed-gender classrooms. Students undertook identical tests irrespective of classroom type, which were graded in accordance with U.K national curriculum guidelines. Controlling for students’ prior attainment, findings indicate that students do not appear to benefit from being taught in single-gender relative to mixed-gender classrooms in Language and STEM-related subjects. Young women benefitted from being taught in mixed-gender relative to single-gender classes for Non-STEM subjects. However, when prior ability is not controlled for, the intervention appears to be effective for all school subjects, highlighting the confounding influence of selective admissions. These findings suggest that gender-segregated classroom initiatives may not bolster students’ grades. It is argued that studies that do not control for selection effects may tell us little about the effectiveness of such interventions on scholastic achievement.     

Reading aloud and the question of intent

Must readers intend to process a word to activate various levels of representation, or is such processing simply triggered by the presentation of a word (i.e., is it “automatic”)? This issue was addressed via the use of Besner and Care’s Task Set paradigm. On each trial a cue, which indicated which of two tasks to perform appeared either before the target, or at the same time as the target. If subjects can process the target while preparing a task set, then the effect of a manipulated psycholinguistic factor should be absorbed into the time taken to process the cue. Despite robust main effects of SOA and word frequency there was no interaction between these factors when the task was to read aloud. This result implies that target processing is delayed until the subject knows what task to perform, and therefore that intention plays an important role when reading words aloud.     

When less is more: Consumer aversion to unused utility

A series of experiments demonstrates that consumers exhibit aversion to waste during forward-looking purchase. These experiments further reveal that such behavior is driven by distaste for unused utility, a reaction that is shown to be distinct from an aversion to squandering money. Waste aversion is especially pronounced when consumers anticipate future consequences and deprivation is salient. In addition to demonstrating robustness across consumers and marketing contexts, the results also demonstrate how waste aversion can lead to self-defeating behavior in which consumers forego desired utility. Finally, the present research demonstrates and discusses the implications of waste aversion for a variety of marketing issues, including buy-rent markets, bundling, and the fundamental distinction between goods and services.     

A Rationale for Evidence-Based Clinical Supervision

Although modern mental health systems increasingly require evidence-based practice (EBP), clinicians continue to object to restrictions on their professional independence, which they may perceive as counterproductive, divisive and even demeaning. In the face of such deep-seated objections, do we really need to strive for an evidence-based approach to supervision? We believe so, and begin our argument by noting a colourful illustration of the problems that can exist in the absence of EBP, those of poor training, therapist drift and weak professional regulation. Next, we present EBP as a mechanism to reduce such unacceptable variability in the way that treatments are delivered. We then apply the lessons from this divisive situation to the practice of clinical supervision, outlining a rationale for an inclusive, synergistic way forward. A number of fundamental psychological motives for this integration are noted, including supervisor training that is informed by practice-based research, corrective feedback on supervision, and a supportive professional system. Illustrative examples are provided in each of these areas. It is concluded that the traditional gulf between research and practice can and should be bridged in relation to supervision.
