A normative study of the Children’s Color Trails Test (CCTT) in the Cypriot population

Background: The Children’s Color Trails Test (CCTT) is a neuropsychological test that measures attention, divided attention, and speed of mental processing. It has been increasingly used in the assessment of children in cross-cultural environments for neurological and psychiatric disorders such as seizures and closed head injuries, learning and/or language disabilities, attention deficit/hyperactivity disorder, children with manganese exposure, and children diagnosed with HIV virus. However, there is a paucity of studies presenting normative data. The aim of the present study was to provide normative data for the CCTT in the Cypriot population. Methods: A total of 709 native Cypriot children aged 7–16 years, recruited from various public schools across the island, took part in the study. Exclusion criteria involved the existence of neurological, psychiatric, cardiological, and metabolic diseases, premature birth, history of maternal alcohol and drug abuse during pregnancy, low birth weight, hearing loss, visual problems, native language other than Greek, and abnormality in fine-motor movements. Results: Age and gender were found to be important factors for the interpretation of scores in all CCTT variables. Older children required less time and exhibited fewer errors, near misses, and prompts compared to younger children. There was a consistent pattern of a 3–4 seconds improvement (less time in seconds) in the CCTT completion time as age increased. Conclusions: CCTT is a promising tool for the measurement of attention in the native Cypriot population. Further research is needed in children diagnosed with various neurological and psychiatric diseases in order to estimate validity of the CCTT in clinical populations.     

Visual Perception and Memory Impairments in Children at Risk of Nonverbal Learning Disabilities

Visuospatial working memory (VSWM) and visual perception were examined in two groups aged 11–13, one with children displaying symptoms of nonverbal learning disability (NLD) (n = 18) and the other a control group without learning disabilities (n = 18). The two groups were matched for general verbal abilities, age, gender, and socioeconomic level. The children were presented with VSWM tests involving visual and spatial-simultaneous processes, and also with a classical visual illusion, a classical ambiguous figure, as well as visual perception tests specifically devised for the present study. Results revealed that performance of children at risk of NLD was worse than controls in some VSWM and in visual perception tests without memory involvement; these latter required comparisons of visual stimuli and locations in space with distractors. Moreover, the two groups differed in perceiving the classical ambiguous figure. Findings are discussed in the light of both theoretical and clinical implications.     

How semantic category modulates preschool children’s visual memory

The dynamic interplay between perception and memory has been explored in preschool children by presenting filtered stimuli regarding animals and artifacts. The identification of filtered images was markedly influenced by both prior exposure and the semantic nature of the stimuli. The identification of animals required less physical information than artifacts did. Our results corroborate the notion that the human attention system evolves to reliably develop definite category-specific selection criteria by which living entities are monitored in different ways.     

Charting the Developmental Trajectories of Attention and Executive Function in Chinese School-Aged Children

Attention is a complex domain that has reawakened research interest in recent years. There are relatively few studies that have examined age-related changes across different attention subcomponents, such as selection, maintenance, and control, using large samples covering a wide age range. The present study assessed performance in 466 participants in order to identify the ages at which mature performance was reached across differing attention subcomponents. Furthermore, we investigated whether the nature of the attentional demands or task difficulty predicted the age at which stable levels of performance were reached. The results supported the former rather than the latter alternative.     

An anxiety-induced bias in the perception of a bistable point-light walker

Human sensitivity for social cues is exquisite, as illustrated by the ease with which simplified point-light movements invoke social and emotional responses. Compared to faces, these biological motion stimuli only recently started to be used to explore questions regarding social cognition and anxiety. We presented human point-light walkers that could be perceived as facing towards or facing away from the observer, and tested whether participants with high social anxiety would perceive these bistable stimuli differently, because this type of stimuli has particular relevance for them. The results showed that observers with high social anxiety tended to see walkers as facing away more frequently than those with low social anxiety. This may mean that high socially anxious observers are biased towards the more positive perceptual alternative because they are motivated to protect themselves against threatening social experiences, but we also explore alternative explanations. The findings are in line with the evidence for a positivity bias in perception, also called wishful seeing, but in contrast with the attentional negativity bias often found in social anxiety. We discuss reasons for this divergence and possible limitations of the current study.     

Simultaneous attentional guidance by working-memory and selection history reveals two distinct sources of attention

Recent theories of attention have proposed that selection history is a separate, dissociable source of information that influences attention. The current study sought to investigate the simultaneous involvement of selection history and working-memory on attention during visual search. Experiments 1 and 2 used target feature probability to manipulate selection history and found significant effects of both working-memory and selection history, although working-memory dominated selection history when they cued different locations. Experiment 3 eliminated the contribution of voluntary refreshing of working-memory and replicated the main effects, although selection history became dominant. Using the same methodology, but with reduced probability cue validity, both effects were present in Experiment 4 and did not significantly differ in their contribution to attention. Effects of selection history and working-memory never interacted. These results suggest that selection history and working-memory are separate influences on attention and have little impact on each other. Theoretical implications for models of attention are discussed.     

A laboratory analogue of mirrored-self misidentification delusion: The role of hypnosis,suggestion, and demand characteristics

Mirrored-self misidentification is the delusional belief that one’s own reflection in the mirror is a stranger. In two experiments, we tested the ability of hypnotic suggestion to model this condition. In Experiment 1, we compared two suggestions based on either the delusion’s surface features (seeing a stranger in the mirror) or underlying processes (impaired face processing). Fifty-two high hypnotisable participants received one of these suggestions either with hypnosis or without in a wake control. In Experiment 2, we examined the extent to which social cues and role-playing could account for participants’ behaviour by comparing the responses of 14 hypnotised participants to the suggestion for impaired face processing (reals) with those of 14 nonhypnotised participants instructed to fake their responses (simulators). Overall, results from both experiments confirm that we can use hypnotic suggestion to produce a compelling analogue of mirrored-self misidentification that cannot simply be attributed to social cues or role-playing.     

Test anxiety and metacognitive skillfulness: Availability versus production deficiencies

Abstract

This paper focuses on the role of metacognition in test anxiety. In two experiments, the metacognitive skillfulness of high vs. low test-anxious secondary school students was contrasted. Low test-anxious subjects exhibited a superior metacognitive skillfulness during math performance relative to high test-anxious subjects. Furthermore, differences in metacognitive skillfulness were performance related. In order to unravel causality in the relation between metacognition and test anxiety, two types of test-anxious students may be distinguished analogous to Naveh-Benjamin (1991). Type-1 students would lack metacognitive skills (availability deficiency), through which they experience failure and develop test anxiety. Type-2 students would experience task irrelevant thoughts, which causes cognitive interference with available metacognitive skills (production deficiency). Results of Study 1 reveal that metacognitive cueing may represent an adequate method for the identification of both types. Due to time-constraints, metacognitive cueing in Study 2 failed to do so.     

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.     

Traditional group therapy and computer-administered treatment for test anxiety

Abstract

Traditional group therapy for test anxiety, modelled after Weissberg (1976), was compared with the computer-administered treatment of Thoresen, Insel, Roth, Ross, and Seyler (1986). Both treatments contained cognitive and behavioral elements including systematic desensitization and Jacobsonian relaxation techniques. The participants were 36 test-anxious students seeking treatment within a university counseling center. Effectiveness of each treatment was assessed by studying changes in test anxiety (total, worry, emotionality), as measured by the Test Anxiety Inventory (Spielberger, 1980). and changes in grade point average (GPA). There was a statistically significant reduction in the three test anxiety measures for both treatments. No significant differences in GPA, as a result of the treatment, were found. There was no significant difference in reduction of test anxiety between the treatments. These findings support the efficacy of the computerized treatment which may be a suitable alternative to group therapy and, in some situations, may be the treatment of choice.
