The development of sustained attention in children: the effect of age and task load.

This study explored how children's sustained attention develops and the effect of manipulating task parameters on sustained attention. The sample comprised 57 children (5-12 years) who completed CogState and Score! (Test of Everyday Attention for Children). Novel variability and traditional indices indicated rapid development from 5-6 to 8-9 years on all measures and a developmental plateau from 8-9 to 11-12, with growth evident on some measures. Findings suggest that sustained attention improves to age 10, then plateaus with only minor improvements. Further, performance was generally poorer on high load tasks compared to low load, with the same developmental pattern uncovered.     

The contribution of anxiety and depression to fatigue among a sample of Australian university students: suggestions for university counsellors

Responses to the Zung Self-Rating Anxiety Scale (SAS: Zung, W. (1971). A rating instrument for anxiety disorders. Psychosomatics, 12, 371–379), the Self-Rating Depression Scale (SDS: Zung, W. (1973). From art to science: The diagnosis and treatment of depression. Archives of General Psychiatry, 29, 328–337) and the Fatigue Severity Scale (FSS) developed by Krupp and colleagues (Krupp, L.B., LaRocca, N.G., Muir-Nash, J., & Steinberg, A.D. (1989). The fatigue severity scale: Application to patients with multiple sclerosis and systemic lupus erythematosus. Archives of Neurology, 46, 1121–1123) were collected from 200 Australian university students to explore the links between these three disorders. Reliability data were satisfactory for all three scales and there were no significant gender or age-related differences between total scale scores. Factor analyses revealed a 5-factor solution for the SAS, a 6-factor solution for the SDS and a single factor for the FSS. There were 8 major and meaningful correlations found and these were entered into a regression of the SAS and SDS factor scores upon the single factor of the FSS. Fatigue factor scores were most powerfully predicted by psychomotor agitation, pain and resultant fatigue and cognitive and emotional arousal factor scores from the SAS and SDS. These data argue for an arousal/anxiety-fatigue-depression progression in disease that may be developmental or accumulative, with extreme levels of psychomotor arousal, resultant muscle fatigue and pain, plus concurrent elevated emotional state and cognitive arousal contributing to an eventual depletion of physical resources, leaving the individual in extreme fatigue. Implications for diagnosis and treatment by counsellors are discussed.     

Within-category discriminations in speech perception

The assumption that listeners are unaware of the highly encoded acoustic properties which lead to phoneme identification is questioned in the present study. It was found that some subjects can make use of small differences in voice onset time when making within-category discriminations. Subjects who can use these auditory features do so both implicitly (in a phonetic match task) and deliberately (in a physical match task). Results also indicate that some type of parallel process model is needed to account for the processing of auditory and phonetic information.     

Prototypes and dimensions of masculinity and femininity

Sex Roles - Researchers have criticized existing measures of masculinity and femininity, largely on the basis of their unidimensional nature. The purpose of the present research was twofold: first,...     

Resolving semantically induced tip-of-the-tongue states for proper nouns

Three experiments are reported in which tip-of-the-tongue states (TOTSs) were induced in subjects by reading them pieces of item-specific information. In Experiments 1 and 2, subjects attempted to name famous people. These experiments showed that, in a TOTS, seeing a picture of the face of the target person did not facilitate naming, whereas the initials of the person's name did. In Experiment 3, a similar result was obtained with a landmark-naming task. The results of the experiments are discussed with reference to current models of memory structure and name retrieval.     

Recall of order information by deaf signers: Phonetic coding in temporal order recall

To examine the claim that phonetic coding plays a special role in temporal order recall, deaf and hearing college students were tested on their recall of temporal and spatial order information at two delay intervals. The deaf subjects were all native signers of American Sign Language. The results indicated that both the deaf and hearing subjects used phonetic coding in short-term temporal recall, and visual coding in spatial recall. There was no evidence of manual or visual coding among either the hearing or the deaf subjects in the temporal order recall task. The use of phonetic coding for temporal recall is consistent with the hypothesis that recall of temporal order information is facilitated by a phonetic code.     

Is vocational assessment training in counseling psychology programs too restricted?

To gather information about vocational assessment training in counseling psychology programs, we surveyed the 64 programs that comprised the Council of Counseling Psychology Training Programs. A total of 56 (88%) directors returned their questionnaires. The survey data suggest that the Strong Interest Inventory (SII), in comparison to other vocational assessment methods, is taught in far more graduate programs and seemingly is accorded a relatively exclusive place in vocational assessment training. In discussing the results, we acknowledge the psychometric soundness and usability of the SII, lament the fact that students appear to receive limited exposure to other valuable vocational assessment tools during their training, and recommend that greater diversity be incorporated into the vocational assessment training of counseling psychology students.     

Mental rotation of faces

The effect of orientation upon face recognition was explored in two experiments, which used a procedure adapted from the mental rotation literature. In the first experiment, a linear increase in the RT of same-different judgments was found as the second of a pair of sequentially presented faces was rotated away from the vertical. Also, it was found that the effect of changing facial expression did not interact with orientation. In the second experiment, a linear relationship between RT and orientation was found in a task involving the recognition of famous faces. This recognition task was found to be more affected by inversion than was an expression classification task. These results are interpreted as evidence against the view that inverted faces are processed in a qualitatively different manner from upright faces, and are also inconsistent with the hypothesis that inversion makes faces difficult to recognize because facial expression cannot be extracted from an inverted face.     

Interference effects in tone memory

Memory for a standard tone in comparison to a subsequent test tone was examined in three experiments with three intervening tones between the standard and test tones. In each trial, the intervening tones were presented from one of seven frequency range and distance from the standard tone conditions. Experiment 1 tone patterns were played at four different presentation rates, and the subjects judged whether the test was higher or lower than the standard. Memory interference effects caused by the different intervening tone conditions could be accounted for by a directional shift in the standard tone memory toward the intervening tones and by a general decrease in the standard tone memory strength with more distant intervening tones. Interference effects were smaller for the rapid presentation rates because the intervening tones formed separate "perceptual streams." Two additional experiments presented the tone patterns in a task requiring the subjects to match a continuously variable tone to their memory of the standard (Experiment 2) and a task requiring them to judge whether the standard and test tones were the "same" or "different" (Experiment 3). These experiments showed large differences in interference effects as a function of the required judgment and the subjects' musical experience.     

Organizing factors in remembering and comprehending: A developmental analysis

This report describes an experiment that emphasizes: (a) the influence of organizing factors in remembering and comprehending and (b) the development of those skills that are related to the ability to organize. The analysis of the data was based on a theory of comprehension that emphasized a pair of interrelated processes, one providing for the construction of a schema or plan and the other for the semantic integration of items into the evolving plan. As predicted, adults perform more accurately with the paragraphs vs. the scrambled paragraphs and with the word lists as compared to the scrambled word lists. Accuracy with unrelated words is generally greater than with related words, a finding that is consistent with a reconstructive theory of remembering. The pattern of results for the 5th grade Ss is quite different: they perform more accurately with the scrambled paragraphs than with the paragraphs and somewhat more accurately with scrambled word lists rather than with word lists. These results were interpreted as evidence for a problem of control for the 5th grade Ss. We have assumed that the ability to process certain forms of information depends upon the ability to select and maintain an appropriate focus of attention. The results for these younger Ss suggest that their ability to file information into a schema as a filing system is compromised by the need to change or modify the filing system.
