The acquisition of the label “stuttering” by primary level schoolchildren

Two groups of primary level schoolchildren were asked to listen to recordings of a familiar story. One recording was of fluent speech and the second of stuttered speech. Group I, composed of 30 children in the first and second grades, was able to differentiate between stuttered and fluent speech, but did not label disfluent behavior as “stuttering.” Group II, composed of 30 children in the third and fourth grades, not only differentiated the samples, but showed a tendency to label the disfluent behavior “stuttering.” Both groups indicated a preference for the fluent sample.     

The Effect of Size of Pupil on the Form and Color Fields

The construct validity of the Wallach-Kogan (W-K) creativity test was investigated through an hierarchical factor analysis of intercorrelations among intelligence, creativity, control, and criterion variables for 73 Ss enrolled in grades 3 and 4 of an inner-city parochial school. The results provided considerable support for W-K's theoretical formulations. Creativity and intelligence assessors defined separate domains and remained totally resilient to merger into a superordinate factor. The creativity domain, which was defined by W-K subtests and criterion ratings, included the following factors: general, visual, and verbal creativity plus a weak methods factor for crayon drawings. The intelligence domain, which was defined by WISC subtests, included a relatively strong g factor and the following four primary factors: verbal precision, freedom from distractibility, perceptual organization, and quasi-specific.     

The creative thinking,environmental frustration,and self‐concept of left‐ and right‐handers

Abstract:

Left‐ (n = 12) and right‐handed (n = 12) college students were compared on creative thinking, environmental frustration, and self‐concept. It was hypothesized that because left‐handers regularly encounter equipment designed for right hand use, these individuals must use creative thinking to successfully interact with the environment. Results indicated that on the Environmental Frustration Questionnaire, left‐handers indicated significantly greater frustration with two of the six categories of objects, namely household tools (p < .005) and classroom desks (p < .005). On the Verbal and Figural Forms of the Torrance Tests of Creative Thinking, lefthanders scored significantly higher on the figural elaboration measure (p < .05). Finally, the hypothesis that handedness plays a larger role in the self‐concept of left‐handers than right‐handers was confirmed. Left‐handers were significantly more likely than right‐handers to mention their handedness when asked to describe themselves (p < .05).     

Human–Robot Interaction in the Context of Simulated Route Reconnaissance Missions

The goal of this research was to examine the ways in which human operators interact with simulated semiautonomous unmanned ground vehicles (UGVs), semiautonomous unmanned aerial vehicles (UAVs), and teleoperated UGVs (Teleop). Robotic operators performed parallel route reconnaissance missions with each platform alone and with all three platforms. When given all three platforms, participants failed to detect more targets than when given only the UAV or UGV; they were also less likely to complete their mission in the allotted time. Target detection during missions was the poorest with the Teleop alone, likely because of the demands of remote driving. Spatial ability was found to be a good predictor of target-detection performance. However, slowing sensor feed video frame rate or the imposition of a short response latency (250 ms) between Teleop control and Teleop reaction failed to affect target-detection performance significantly. Nevertheless, these video image manipulations did influence assessment of system usability.     

Cognitive and Social Factors Associated with NSSI and Suicide Attempts in Psychiatrically Hospitalized Adolescents

Although non-suicidal self-injury (NSSI) and suicide attempts (SA) frequently co-occur among youth, there is increasing evidence that both the risk factors and the phenomenology of the behaviors are distinct. This study examined how individuals who engage in NSSI only, individuals who attempt suicide only, and those who have histories of both NSSI and at least one suicide attempt may differ in terms of cognitions and perceived social support. Participants were 185 adolescents (78.1 % female) between the ages of 13 and 18 recruited from a psychiatric inpatient facility in the northeastern United States. One hundred forty-eight teens were identified with a history of self-injurious behavior and divided into three groups: NSSI only (n?=?45), SA only (n?=?24) or both NSSI and SA (NSSI+SA; n?=?79). Analyses showed that the NSSI+SA group exhibited more cognitive errors, negative self-statements, and negative views of self, world, and future, as well as less perceived familial support than either the NSSI or SA only groups. There were no differences between groups on perceived support from teachers or peers. No significant demographic or diagnostic differences were found between the NSSI and SA groups. Limitations and clinical implications of the current research are discussed.     

Psychological impact of benign breast biopsy: a longitudinal, comparative study.

The impact of benign breast biopsy (BBB) on distress and perceptions of risk for breast cancer (BC) was examined. Interviews were conducted with 100 women shortly after notification of biopsy results and 4 and 8 months post-BBB. Compared with matched healthy comparison (HC) women without BBB, the BBB group evidenced greater BC-specific distress at baseline. BC-specific distress declined after BBB, remaining elevated relative to the HC group at the 8-month follow-up. Dispositional (optimism, informational coping style), demographic (education), clinical (family history of BC), and cognitive (BC risk perception) variables were associated with baseline levels of BC-specific distress or persistence of distress. Results support the monitoring process model (S. M. Miller, 1995) and the cognitive social health information processing model (S. M. Miller, Y. Shoda, & K. Hurley, 1996).     

Multilevel Selection Theory and Major Evolutionary Transitions: Implications for Psychological Science

ABSTRACT— The concept of a group as comparable to a single organism has had a long and turbulent history. Currently, methodological individualism dominates in many areas of psychology and evolution, but natural selection is now known to operate at multiple levels of the biological hierarchy. When between-group selection dominates within-group selection, a major evolutionary transition occurs and the group becomes a new, higher-level organism. It is likely that human evolution represents a major transition, and this has wide-ranging implications for the psychological study of group behavior, cognition, and culture.     

The effect of occlusion on the semantics of projective spatial terms: a case study in grounding language in perception

Although data-driven spatial template models provide a practical and cognitively motivated mechanism for characterizing spatial term meaning, the influence of perceptual rather than solely geometric and functional properties has yet to be systematically investigated. In the light of this, in this paper, we investigate the effects of the perceptual phenomenon of object occlusion on the semantics of projective terms. We did this by conducting a study to test whether object occlusion had a noticeable effect on the acceptance values assigned to projective terms with respect to a 2.5-dimensional visual stimulus. Based on the data collected, a regression model was constructed and presented. Subsequent analysis showed that the regression model that included the occlusion factor outperformed an adaptation of Regier & Carlson’s well-regarded AVS model for that same spatial configuration.
