Auditory change detection: simple sounds are not memorized better than complex sounds

Previous research has shown that the detectability of a local change in a visual image is essentially independent of the complexity of the image when the interstimulus interval (ISI) is very short, but is limited by a low-capacity memory system when the ISI exceeds 100 ms. In the study reported here, listeners made same/different judgments on pairs of successive "chords" (sums of pure tones with random frequencies). The change to be detected was always a frequency shift in one of the tones, and which tone would change was unpredictable. Performance worsened as the number of tones increased, but this effect was not larger for 2-s ISIs than for 0-ms ISIs. Similar results were obtained when a chord was followed by a single tone that had to be judged as higher or lower than the closest component of the chord. Overall, our data suggest that change detection is based on different mechanisms in audition and vision.     

Evaluation of Peer Comforting Strategies by Children and Adolescents

Despite the importance of social support across the lifespan and extensive research on supportive communication between adults, little is known about how children or adolescents respond to the comforting efforts of their peers. The current study was designed to examine how 5th, 7th, and 9th graders evaluate six peer comforting strategies (sympathy, account giving, companionship, advice, optimism, and minimization) and to assess moderating effects of age, gender, and situation. Participants (N= 292) read scenarios involving a social rejection or academic failure and rated messages for affective improvement and perceived caring. Results indicated that companionship was the most positively evaluated strategy on both dependent variables, whereas minimization and account were least positively evaluated; sympathy, advice, and optimism received intermediate evaluations. These results were somewhat moderated by age, gender, and situation. Results are discussed with respect to potential differences between adult and tween evaluations and expectations in comforting interactions.     

Deliberative Discourse Idealized and Realized: Accountable Talk in the Classroom and in Civic Life

Classroom discussion practices that can lead to reasoned participation by all students are presented and described by the authors. Their research emphasizes the careful orchestration of talk and tasks in academic learning. Parallels are drawn to the philosophical work on deliberative discourse and the fundamental goal of equipping all students to participate in academically productive talk. These practices, termed Accountable Talk^SM, emphasize the forms and norms of discourse that support and promote equity and access to rigorous academic learning. They have been shown to result in academic achievement for diverse populations of students. The authors outline Accountable Talk as encompassing three broad dimensions: one, accountability to the learning community, in which participants listen to and build their contributions in response to those of others; two, accountability to accepted standards of reasoning, talk that emphasizes logical connections and the drawing of reasonable conclusions; and, three, accountability to knowledge, talk that is based explicitly on facts, written texts, or other public information. With more than fifteen years research into Accountable Talk applications across a wide range of classrooms and grade levels, the authors detail the challenges and limitations of contexts in which discourse norms are not shared by all members of the classroom community.

Passive tactile feedback facilitates mental rotation of handheld objects

Mental rotation of objects improves when passive tactile information for the rotating object accompanies the imagined rotation (Wraga, Creem, & Proffitt, 2000). We examined this phenomenon further using a within-subjects paradigm involving handheld objects. In Experiment 1, participants imagined rotating an unseen object placed on their upturned palms. The participants were faster at mental rotation when the object was rotated on their palm than when the object remained stationary. Experiment 2 tested whether the performance advantage would endure when the participants received tactile information for only the start- and endpoints of the rotation event. This manipulation did not improve performance, relative to a stationary control. Experiment 3 revealed that ambiguous tactile information, continuous with the rotation event but independent of object shape, actually degraded performance, relative to a stationary control. In Experiment 4, we found that continuous tactile rotation discrepant from imagined object movement also hindered performance, as compared with continuous tactile information aligned with imagined object movement. The findings suggest a tight coupling between tactile information specifying continuous object rotation and the corresponding internal representation of the rotating object.     

Recalling taboo and nontaboo words

People remember emotional and taboo words better than neutral words. It is well known that words that are processed at a deep (i.e., semantic) level are recalled better than words processed at a shallow (i.e., purely visual) level. To determine how depth of processing influences recall of emotional and taboo words, a levels of processing paradigm was used. Whether this effect holds for emotional and taboo words has not been previously investigated. Two experiments demonstrated that taboo and emotional words benefit less from deep processing than do neutral words. This is consistent with the proposal that memories for taboo and emotional words are a function of the arousal level they evoke, even under shallow encoding conditions. Recall was higher for taboo words, even when taboo words were cued to be recalled after neutral and emotional words. The superiority of taboo word recall is consistent with cognitive neuroscience and brain imaging research.     

Children's working understanding of the knowledge gained from seeing and feeling

In three experiments (N = 48 3‐ to 4‐year olds; 100 3‐ to 5‐year olds; 54 4‐year‐olds), children who could see or feel a target toy, recognized when they had sufficient information to answer ‘Which one is it?’ and when they needed additional access. They were weaker at taking the informative modality of access when the choice was between seeing more of a partially visible toy and feeling it; at doing so when the target was completely hidden; and at reporting seeing or feeling as their source of knowledge of the target's identity having experienced both. Working understanding of the knowledge gained from seeing and feeling (identifying the target efficiently) was not necessarily in advance of explicit understanding (reporting the informative source).     

The manifestation of transference during early psychotherapy sessions

Despite the clinical use of therapeutic transference across various schools of psychotherapy, there have been relatively few empirical studies of this phenomenon, none of which has examined transference with a non‐pathological population. In this study, the core conflictual relationship theme (CCRT) method was used to examine the manifestation of therapeutic transference in the first three sessions of 22 counselling contracts with high‐functioning individuals. Factor analyses of the wish (W) and response of other (RO) components of the CCRT indicate a complementary pattern of relating in which the therapist is idealised and others are devalued. Within the response of self (RS) component, clients exhibited a concordant relational transfer whereby they had a negative response to both the therapist and others. Additionally, control issues emerged in the W component for significant others and in the RS component for the therapist.     

Can CORE assessment data identify those clients less likely to benefit from brief counselling in primary care?

Studies show that counsellors in primary care see many clients with difficulties of a severity similar to those found in secondary care services. Evidence from both RCTs and studies of routinely collected data indicates that many of these ‘clinical’ clients benefit from brief counselling intervention. However, little is known about why some benefit while others fail to do so despite completing their counselling contract. This paper considers client characteristics recorded at assessment and aims, using logistic regression analysis, to identify those characteristics predictive of a poor outcome. Results indicate that a number of characteristics are associated with poor outcome; the most important predictors are economic inactivity and aspects of the patient's condition, particularly continuous/recurrent depression, with some differences between genders. However, the models produced were not acceptable in their predictive power. This may be partly due to data quality issues or important characteristics not being available in the data. The paper concludes that being unemployed or on state benefits may be a proxy measure of severity that has an important impact on outcome for all patients, and particularly for males. Some reasons are suggested and areas of future research are identified.     

Locomotor experience and use of social information are posture specific

The authors examined the effects of locomotor experience on infants' perceptual judgments in a potentially risky situation--descending steep and shallow slopes--while manipulating social incentives to determine where perceptual judgments are most malleable. Twelve-month-old experienced crawlers and novice walkers were tested on an adjustable sloping walkway as their mothers encouraged and discouraged descent. A psychophysical procedure was used to estimate infants' ability to crawl/walk down slopes, followed by test trials in which mothers encouraged and discouraged infants to crawl/walk down. Both locomotor experience and social incentives affected perceptual judgments. In the encourage condition, crawlers only attempted safe slopes within their abilities, but walkers repeatedly attempted impossibly risky slopes, replicating previous work. The discourage condition showed where judgments are most malleable. When mothers provided negative social incentives, crawlers occasionally avoided safe slopes, and walkers occasionally avoided the most extreme 50 degrees increment, although they attempted to walk on more than half the trials. Findings indicate that both locomotor experience and social incentives play key roles in adaptive responding, but the benefits are specific to the posture that infants use for balance and locomotion.
