Attention to distinguishing features in object recognition

This study advances the hypothesis that, in the course of object recognition, attention is directed to distinguishing features: visual information that is diagnostic of object identity in a specific context. In five experiments, observers performed an object categorization task involving drawings of fish (Experiments 1–4) and photographs of natural sea animals (Experiment 5). Allocation of attention to distinguishing and non-distinguishing features was examined using primed-matching (Experiment 1) and visual probe (Experiments 2, 4, 5) methods, and manipulated by spatial precuing (Experiment 3). Converging results indicated that in performing the object categorization task, attention was allocated to the distinguishing features in a context-dependent manner, and that such allocation facilitated performance. Based on the view that object recognition, like categorization, is essentially a process of discrimination between probable alternatives, the implications of the findings for the role of attention to distinguishing features in object recognition are discussed.     

The role of illness perceptions in the attachment-related process of affect regulation

Abstract

Based on the predictions of the attachment theory and the Common Sense Model of illness perceptions, the current study focused on the role played by illness perceptions in explaining the path linking attachment orientations to negative affect during recovery from cardiac illness. We predicted two putative mechanisms: (1) illness perceptions would mediate the direct association between attachment-related insecurity (especially attachment anxiety) and levels of distress at follow-up and (2) illness perceptions would interact with attachment orientations (attachment avoidance in particular) in explaining patients' distress. The sample consisted of 111 male patients admitted to the Cardiac Care Unit of the Meir Medical Center, located in the central region of Israel. Patients completed a measure of attachment orientations during hospitalization (baseline). One month later, patients' illness perceptions were measured. Patients' depression and anxiety symptoms were measured at baseline and at the six-month follow-up. The associations between attachment-related anxiety and anxiety symptoms at follow-up were fully mediated by illness perceptions. Attachment-related avoidance was found to interact with illness perceptions in the prediction of depressive symptoms at follow-up. The findings shed light on the possible dynamics among personality, cognitive appraisals, and affect regulation efforts when coping with illness.     

Identity Thieves and Levels of Sophistication: Findings from a National Probability Sample of American Newspaper Articles 1995–2005

Identity theft continues to be a problem in the United States, yet research on identity thieves is limited. This study complements previous work by exploring the correlates of identity thieves (n = 257) and offense sophistication levels via a content analysis of a nationally representative probability sample of newspaper articles (1995–2005). Sample demographics are presented along with the results from bivariate correlations and a multinomial logit model focused on exploring variation in correlate influence on four levels of identity theft sophistication.     

THE EFFECT OF NOTE TAKING ON NINTH GRADE STUDENTS' COMPREHENSION

This study examined factors affecting motivation for reading, writing, and spelling in primary grade students using a new measure, the Early Literacy Motivation Survey (ELMS). First-graders (198) responded to questions measuring attributions, self-efficacy, and perceived competence. The ELMS uses scenarios and short tasks to contextualize the questions for young children. A confirmatory factor analysis validated the motivation constructs investigated. A structural equation model produced a good fit for the data and indicated that literacy attributions in young children mediated between achievement and self-efficacy and perceived competence. Findings showed that first-grade students differentiate among their self-efficacy for reading, writing, and spelling.     

Attention and Memory in Children with Brain Tumors

The Rey Auditory Verbal Learning Test was utilized to examine attention, learning, and memory abilities in 42 children with cerebellar (N?=?18) and third ventricle tumors (N?=?24). Children with cerebellar tumors exhibited significant auditory attentional impairments and displayed adequate encoding and retrieval across subsequent learning and memory trials. In contrast, children with third ventricle tumors exhibited average auditory attentional abilities, but they displayed mild encoding deficits across trials 2–5. Furthermore, the third ventricle group's compromised performance on the delayed recall trial and average performance on the delayed recognition trial is suggestive of underlying retrieval deficits.     

Correlates of Dispositional and State Flow in Tennis Competition

The purpose of this study was to investigate the relationship between psychological correlates and flow in tennis competition. Using a cross-sectional design, the sample of 261 junior tennis athletes showed moderate-to-strong correlations between flow (dispositional and state) and confidence (r _disp = .59; r _state = .35), imagery use (r _disp = .58; r _state = .32), and action control (r _disp = .41; r _state = .40), whereas absorption was orthogonal to flow. Commonality analysis revealed that imagery and confidence accounted for 34.2% of the variance in dispositional flow. The results are discussed for the development of intervention studies in order to enhance flow in competition.     

Transversus abdominis is part of a global not local muscle synergy during arm movement

The trunk muscle transversus abdominis (TrA) is thought to be controlled independently of the global trunk muscles. Methodological issues in the 1990s research such as unilateral electromyography and a limited range of arm movements justify a re-examination of this theory. The hypothesis tested is that TrA bilateral co-contraction is a typical muscle synergy during arm movement. The activity of 6 pairs of trunk and lower limb muscles was recorded using bilateral electromyography during anticipatory postural adjustments (APAs) associated with the arm movements. The integrated APA electromyographical signals were analyzed for muscle synergy using Principle Component Analysis. TrA does not typically bilaterally co-contract during arm movements (1 out of 6 participants did). APA muscle activity of all muscles during asymmetrical arm movements typically reflected a direction specific diagonal pattern incorporating a twisting motion to transfer energy from the ground up. This finding is not consistent with the hypothesis that TrA plays a unique role providing bilateral, feedforward, multidirectional stiffening of the spine. This has significant implications to the theories underlying the role of TrA in back pain and in the training of isolated bilateral co-contraction of TrA in the prophylaxis of back pain.     

A China–New Zealand comparison of forgiveness

The present study examined the practice of forgiveness among participants from China (N = 172) and New Zealand (N = 91). We tested a theoretical model describing the relationships between collectivism, individualism, and forgiveness. Participants from China were more collectivistic and less individualistic than were participants from New Zealand. Overall, participants from New Zealand were more forgiving than were participants from China. Collectivism was positively related to decisional forgiveness in Chinese participants. Decisional forgiveness independently predicted conciliatory behaviour among participants from China, but this was not the case for participants from New Zealand. Thus, the hypothesized model received qualified support.
