The internal clock: Electroencephalographic evidence for oscillatory processes underlying time perception

It has been proposed that temporal perception and performance depend on a biological source of temporal information. A model for a temporal oscillator put forward by Treisman, Faulkner, Naish, and Brogan (1990) predicted that if intense sensory pulses (such as auditory clicks) were presented to subjects at suitable rates they would perturb the frequency at which the temporal oscillator runs and so cause over- or underestimation of time. The resulting pattern of interference between sensory pulse rates and time judgments would depend on the frequency of the temporal oscillator and so might allow that frequency to be estimated. Such interference patterns were found using auditory clicks and visual flicker (Treisman & Brogan, 1992; Treisman et al., 1990). The present study examines time estimation together with the simultaneously recorded electroencephalogram to examine whether evidence of such an interference pattern can be found in the EEG.

Alternative models for the organization of a temporal system consisting of an oscillator or multiple oscillators are considered and predictions derived from them relating to the EEG. An experiment was run in which time intervals were presented for estimation, auditory clicks being given during those intervals, and the EEG was recorded concurrently. Analyses of the EEG revealed interactions between auditory click rates and certain EEG components which parallel the interference patterns previously found. The overall pattern of EEG results is interpreted as favouring a model for the organization of the temporal system in which sets of click-sensitive oscillators spaced at intervals of about 12.8 Hz contribute to the EEG spectrum. These are taken to represent a series of harmonically spaced distributions of oscillators involved in time-keeping.     

Attention to local form information can prevent access to semantic information.

Humphreys and Boucart (1997) have shown that when processing of local form is required for response, surrounding global information is automatically processed to a semantic level. The generality of this effect was investigated in two experiments in which the perceptual load of the relevant local form information was manipulated, as was uncertainty about perceptual load. Participants attended to a single line segment inside a picture of an animal or a vehicle and then decided which of two pictures in the target/distractor display that followed contained a line segment that matched the first in orientation. The perceptual load of the relevant local form information was either low (the matching line segment was one of the solitary line segments presented in the centre ofthe target and distractor pictures), or high (the matching line segment was part of one of the solitary letters presented in the centre of the target and distractor pictures). The semantic relations among the pictures were manipulated, and when perceptual load remained constant across trials, semantic relations affected performance in the low-load but not in the high-load condition. When perceptual load varied from trial to trial, there was no evidence of any semantic processing on either low- or high-load trials. The results suggest that in form-matching tasks, attentional priority can be given to local information, thus preventing access to semantic information derived from global shape. They further suggest that the distribution of attention is not dictated entirely by the actual perceptual demands of the relevant stimulus, indicating an important role for top-down processing.     

Does Mother Know Best? An Actor–Partner Model of College‐Age Women's Human Papillomavirus Vaccination Behavior

This study examined the associations of perceived threat, perceived efficacy, and parent–child communication with the extent to which college‐age women received the human papillomavirus (HPV) vaccine. Daughters and their mothers completed a survey about the HPV vaccine (N = 182 dyads). The results showed that mothers' perceived self‐efficacy to talk to their daughters and mothers' response efficacy of the vaccine were indirectly related to mother–daughter communication about HPV. Further, mother–daughter communication mediated the relation between mothers' intention to talk to their daughters and daughters' HPV vaccination behavior. This study demonstrates the importance of the social context of health behavior and the role of communication in understanding maternal influence on the HPV vaccination behavior of young adult women.     

The Effect of Image Pixelation on Unfamiliar‐Face Matching

Low‐resolution, pixelated images from closed‐circuit television (CCTV) can be used to compare the perpetrators of crime with high‐resolution photographs of potential suspects. The current study investigated the accuracy of person identification under these conditions, by comparing high‐resolution and pixelated photographs of unfamiliar faces in a series of matching tasks. Performance decreased gradually with different levels of pixelation and was close to chance with a horizontal image resolution of only 8 pixels per face (Experiment 1). Matching accuracy could be improved by reducing the size of pixelated faces (Experiment 2) or by varying the size of the to‐be‐compared‐with high‐resolution face image (Experiment 3). In addition, pixelation produced effects that appear to be separable from other factors that might affect matching performance, such as changes in face view (Experiment 4). These findings reaffirm that criminal identifications from CCTV must be treated with caution and provide some basic estimates for identification accuracy with different pixelation levels. This study also highlights potential methods for improving performance in this task. Copyright © 2013 John Wiley & Sons, Ltd.     

Faith and Mental Health in an Oncology Population

This study compares faith attitudes versus behaviors for their relationship to mental health in current cancer patients and survivors. This cross-sectional survey of ambulatory patients included Hodge’s intrinsic religious motivation scale, Benson & Spilka’s concept of God scale, frequency of prayer, and the mental health subscale of the MOS SF-36. One hundred and fifty-eighty patients, mostly women with breast cancer, completed questionnaires (92% return). Mental health was positively related to a concept of a loving God (P < .001) and negatively related to the concept of a stern God (P < .002). Mental health was unrelated to goal of treatment (cure vs. chemotherapy/palliation), frequency of prayer, intrinsic faith motivation, or physical pain. Viewing God as loving was strongly related to better mental health, even in the presence of a poor prognosis or pain.     

Examining the Impact of Training on the Homosexual Conduct Policy for Military Personnel

The impact of training related to the Don't Ask, Don't Tell, Don't Pursue policy on training outcomes of military personnel was examined with data from the Department of Defense Inspector General's Don't Ask, Don't Tell, Don't Pursue Policy Survey of military personnel (N = 71,570). We hypothesized that training related to the Don't Ask, Don't Tell, Don't Pursue policy would impact participant's reactions, learning and cognitive outcomes, and behavioral and organizational outcomes. Results indicate that individuals who reported having received training on the homosexual conduct policy perceived the policy to be more effective at preventing/reducing harassment; were more likely to feel free to report harassment complaints; reported greater levels of understating and were more knowledgeable of the policy; reported higher levels of intolerance of harassment; and reported that more actions had been take at their installation/ship to reduce and prevent harassment than individuals who had not received any training. Although the pattern of results was statistically significant, the magnitude of these effects were small (η ² = .001–.109). These findings highlight the continuing need to expand current efforts to reduce and curtail harassment based on perceived sexual orientation.
