Frequency and Nature of Rumination in Chronic Depression: A Preliminary Study

This study explores the phenomenological experience of rumination in a sample of 22 chronically depressed people and looks at the extent to which it is consistent with theoretical ideas. The findings indicate that, on average, depressed people ruminate about at least two different topics, and that there is wide variability in how long each episode lasts. Rumination is a complex process frequently involving imagery as well as verbal thoughts and is almost invariably associated with multiple emotions. Although there was some evidence for stop rules being involved, most individuals attributed ending a period of rumination to distraction, whether external or internally generated.     

Test anxiety,emotional responding under guided imagery,and self-talk during an academic examination

Abstract

This investigation examined the assumption that phenomenological responses created by guidedimagery procedures pertinent to test anxiety are topographically similar to emotional responses experienced during an actual examination. Participants were divided on facilitating versus debilitating test anxiety and exposed to subclinical doses of stimulus-response propositions that involved test-taking, fear, and physical activity using the induction technique employed by Lang et al. (1980). Patterns of emotional responses obtained after each induction were compared to the pattern elicited immediately prior to students' final course examination as well as self-talk during the examination. Results indicated that exposure to test-related imagery elicited a pattern of emotional responding that was different than exposure to fear or action imagery but was nearly identical to emotional responses found before examinations. Negative emotional states before the examination also were associated with higher frequencies of negative self-statements during the examination. Treatment implications of these findings were explored.     

In search of a surrogate for touch: The effect of haptic imagery on perceived ownership

Previous research has shown that individuals value objects more highly if they own them, a finding commonly known as the endowment effect. In fact, simply touching an object can create a perception of ownership that produces the endowment effect. In this paper, we extend this line of research in several ways. First, we show that haptic imagery, or imagining touching an object, can have the same effect on perceived ownership as physical touch. We then demonstrate that haptic imagery can lead to perceptions of physical control, which in turn increase feelings of ownership. Moreover, the more vivid the haptic imagery, the greater the perception of control and the feeling of ownership. Implications for theory and practice are discussed.     

See an object,hear an object file: Object correspondence transcends sensory modality

An important task of perceptual processing is to parse incoming information into distinct units and to keep track of those units over time as the same, persisting representations. Within the study of visual perception, maintaining such persisting object representations is helped by “object files”—episodic representations that store (and update) information about objects' properties and track objects over time and motion via spatiotemporal information. Although object files are typically discussed as visual, here we demonstrate that object–file correspondence can be computed across sensory modalities. An object file can be initially formed with visual input and later accessed with corresponding auditory information, suggesting that object files may be able to operate at a multimodal level of perceptual processing.     

Can the irrelevant speech effect turn into a stimulus suffix effect?

The irrelevant sound effect (ISE) and the stimulus suffix effect (SSE) are two qualitatively different phenomena, although in both paradigms irrelevant auditory material is played while a verbal serial recall task is being performed. Jones, Macken, and Nicholls (2004) Jones, D. M., Macken, W. J. and Nicholls, A. P. 2004. The phonological store of working memory: Is it phonological and is it a store?. Journal of Experimental Psychology: Learning, Memory, and Cognition, 30: 656–674. [Crossref], [PubMed], [Web of Science ®] , [Google Scholar] have proposed the effect of irrelevant speech on auditory serial recall to switch from an ISE to an SSE mechanism, if the auditory-perceptive similarity of relevant and irrelevant material is maximized. The experiment reported here (n = 36) tested this hypothesis by exploring auditory serial recall performance both under irrelevant speech and under speech suffix conditions. These speech materials were spoken either by the same voice as the auditory items to be recalled or by a different voice. The experimental conditions were such that the likelihood of obtaining an SSE was maximized. The results, however, show that irrelevant speech—in contrast to speech suffixes—affects auditory serial recall independently of its perceptive similarity to the items to be recalled and thus in terms of an ISE mechanism that crucially extends to recency. The ISE thus cannot turn into an SSE.     

Rhythmic sensorimotor coordination is resistant but not immune to auditory stream segregation

In a recent study of musicians' sensorimotor synchronization with auditory sequences composed either of beat and subdivision tones differing in pitch or of beat tones only, Repp (2009) found that the phase correction response (PCR) to perturbed beats was inhibited by the presence of subdivisions regardless of whether beats and subdivisions formed integrated or segregated perceptual streams. The present study used a different paradigm in which perturbed subdivisions triggered the PCR. At the slower of two sequence tempi, the PCR was equally large in integrated and segregated conditions, but at the faster tempo stream segregation reduced the PCR substantially. This new finding indicates that although the PCR is strongly resistant to auditory stream segregation, it is not totally immune to it.     

Intentional attention switching in dichotic listening: Exploring the efficiency of nonspatial and spatial selection

Using an auditory variant of task switching, we examined the ability to intentionally switch attention in a dichotic-listening task. In our study, participants responded selectively to one of two simultaneously presented auditory number words (spoken by a female and a male, one for each ear) by categorizing its numerical magnitude. The mapping of gender (female vs. male) and ear (left vs. right) was unpredictable. The to-be-attended feature for gender or ear, respectively, was indicated by a visual selection cue prior to auditory stimulus onset. In Experiment 1, explicitly cued switches of the relevant feature dimension (e.g., from gender to ear) and switches of the relevant feature within a dimension (e.g., from male to female) occurred in an unpredictable manner. We found large performance costs when the relevant feature switched, but switches of the relevant feature dimension incurred only small additional costs. The feature-switch costs were larger in ear-relevant than in gender-relevant trials. In Experiment 2, we replicated these findings using a simplified design (i.e., only within-dimension switches with blocked dimensions). In Experiment 3, we examined preparation effects by manipulating the cueing interval and found a preparation benefit only when ear was cued. Together, our data suggest that the large part of attentional switch costs arises from reconfiguration at the level of relevant auditory features (e.g., left vs. right) rather than feature dimensions (ear vs. gender). Additionally, our findings suggest that ear-based target selection benefits more from preparation time (i.e., time to direct attention to one ear) than gender-based target selection.     

Encoding strategy affects false recall and recognition: Evidence from categorical study material

The present research investigated memory vulnerability to distortions. Different encoding strategies were used when categorized lists were studied. The authors assumed that an imagery strategy would be responsible for decreasing false memories more than a word-whispering strategy, which is consistent with the model of semantic access and previous research in the Deese-Roediger-McDermott paradigm (the DRM paradigm; Deese, 1959; Roediger & McDermott, 1995). A normative study of category lists and 4 experiments were conducted to verify the memory vulnerability to different encoding strategies (imagery, word-whispering, control). Half of subjects recalled and half recognized previously studied words. The results revealed a marked reduction in false recognition and recall after imagery encoding, relative to after word-whispering encoding.     

Attention and action: The role of response mappings in auditory attention switching

Switching auditory attention incurs a performance decrement (i.e. auditory attention-switch costs). Using an auditory attention-switching paradigm, we aimed to generalise these across different response mappings. In all three experiments, two number words, spoken by a female and male speaker, were presented dichotically via headphones. A visual cue indicated the gender of the to-be-attended speaker in each trial. The task was a magnitude judgement of the relevant number word (i.e. smaller vs. larger than 5). We additionally varied the interval between cue onset and auditory stimulus onset (cue-stimulus interval) to explore cue-based preparatory effects. In Experiment 1, attention switching was more costly with direct-verbal responses (e.g. ‘smaller’) than in the shadowing task (e.g. ‘three’). In Experiment 2, performance was largely similar for direct-verbal responses and abstract-verbal responses (e.g. ‘left’). In Experiment 3, performance was generally worse with abstract-verbal responses than with abstract-manual responses (e.g. left key press) and auditory attention-switch costs were similar for both response mappings. Overall, auditory switch costs occurred more or less invariably across response mappings in categorical (magnitude) judgements suggesting a minor role of the response mapping in auditory attention switching. Furthermore, verbal identity-based judgements (i.e. shadowing) generally seem to benefit from ideomotor compatibility.     

Increasing Behavioral Skills and Level of Understanding in Adults: A Brief Method Integrating Dennison's Brain Gym & #x00AE; Balance with Piaget's Reflective Processes

A single session intervention was given individually to 4 adults in order to assist them in achieving their personal goals by improving their behavioral skills for achieving the goals and their conceptual understanding of & #x201C;how to & #x201D; attain these goals. The method was based on a brain-ability analysis of understanding & #x201C;conservation & #x201D; on Jean Piaget's conservation tasks combined with Paul and Gail Dennison's Brain Gym & #x201C;balance & #x201D; procedure. My & #x201C;whole brain understanding & #x201D; model (C. A. Wolfsont, 1999, 2000) and M. L. Commons et al.'s Hierarchical Complexity Scoring System manual were used to analyze the verbal protocols (M. L. Commons et al., 1992; Commons, Danaher, & Meaney, 2000). Increases were found in the participants' conceptual understanding and in the complexity of their performance.
