Exploring health care professionals views on alternative approaches to cancer follow-up and barriers and facilitators to implementation of a recovery package.

Purpose: To meet the long-term needs of cancer survivors the focus of recent cancer care reform in the United Kingdom (UK) has been the implementation of alternative follow-up strategies to relieve the growing pressures threatening to overwhelm cancer services. In 2013, the UK's National Cancer Survivorship Initiative recommended an integrated package of care called the Recovery Package to meet cancer survivors' psychosocial and information needs and supported self-management.

Method: We aimed to explore health care professionals' views of alternative strategies for follow-up care, and perceived barriers and facilitators to implementation of the Recovery Package for patients who had completed treatment for cancer.

I Don't See It Your Way: The Dot Perspective Task Does Not Gauge Spontaneous Perspective Taking.

Data from studies employing the dot-perspective task have been used to support the theory that humans are capable of automatically computing the visual perspective of other individuals. Recent work has challenged this interpretation, claiming instead that the results may arise through the automatic reorienting of attention triggered by observed head and gaze cues. The two experiments reported here offer a stronger test of the perspective taking account by replacing the computer-generated avatars used in previous research with, respectively, photo-realistic stimuli and socially co-present individuals in a "live", face-to-face version of the task.

Saccades and smooth pursuit eye movements trigger equivalent gaze-cued orienting effects.

Research has established that a perceived eye gaze produces a concomitant shift in a viewer's spatial attention in the direction of that gaze. The two experiments reported here investigate the extent to which the nature of the eye movement made by the gazer contributes to this orienting effect. On each trial in these experiments, participants were asked to make a speeded response to a target that could appear in a location toward which a centrally presented face had just gazed (a cued target) or in a location that was not the recipient of a gaze (an uncued target).

Holistic face processing can inhibit recognition of forensic facial composites.

Facial composite systems help eyewitnesses to show the appearance of criminals. However, likenesses created by unfamiliar witnesses will not be completely accurate, and people familiar with the target can find them difficult to identify. Faces are processed holistically; we explore whether this impairs identification of inaccurate composite images and whether recognition can be improved.

Working memory load disrupts gaze-cued orienting of attention.

A large body of work has shown that a perceived gaze shift produces a shift in a viewer's spatial attention in the direction of the seen gaze. A controversial issue surrounds the extent to which this gaze-cued orienting effect is stimulus-driven, or is under a degree of top-down control. In two experiments we show that the gaze-cued orienting effect is disrupted by a concurrent task that has been shown to place high demands on executive resources: random number generation (RNG).

Developmentally distinct gaze processing systems: luminance versus geometric cues.

Two experiments examined how the different cues to gaze direction contribute to children's abilities to follow and make explicit judgements about gaze. In each study participants were shown blurred images of faces containing only luminance cues to gaze direction, line-drawn images containing only fine-grained detail supporting a geometric analysis of gaze direction, and unmanipulated images. In Experiment 1a, 2- and 3-year olds showed gaze-cued orienting of attention in response to unmanipulated and blurred faces, but not line-drawn faces.

Looking back at the stare-in-the-crowd effect: staring eyes do not capture attention in visual search.

The stare-in-the crowd effect refers to the finding that a visual search for a target of staring eyes among averted-eyes distracters is more efficient than the search for an averted-eyes target among staring distracters. This finding could indicate that staring eyes are prioritized in the processing of the search array so that attention is more likely to be directed to their location than to any other. However, visual search is a complex process, which not only depends upon the properties of the target, but also the similarity between the target of the search and the distractor items and between the distractor items themselves.

The effect of facial expression and gaze direction on memory for unfamiliar faces.

We report data from an experiment that investigated the influence of gaze direction and facial expression on face memory. Participants were shown a set of unfamiliar faces with either happy or angry facial expressions, which were either gazing straight ahead or had their gaze averted to one side. Memory for faces that were initially shown with angry expressions was found to be poorer when these faces had averted as opposed to direct gaze, whereas memory for individuals shown with happy faces was unaffected by gaze direction.

Attention to faces in Williams syndrome.

Williams syndrome (WS) is associated with distinct social behaviours. One component of the WS social phenotype is atypically prolonged face fixation. This behaviour co-exists with attention difficulties.

Gaze perception: is seeing influenced by believing?

Gaze perception has been thought to be stimulus-driven. This view is challenged by a new demonstration that a gaze direction aftereffect can be influenced by beliefs about the gazer's ability to see.

Gaze perception requires focused attention: evidence from an interference task.

The direction of another person's gaze is difficult to ignore when presented at the center of attention. In 6 experiments, perception of unattended gaze was investigated. Participants made directional (left-right) judgments to gazing-face or pointing-hand targets, which were accompanied by a distractor face or hand.

Adaptation effects of highly familiar faces: immediate and long lasting.

A central problem of face identification is forming stable representations from entities that vary--both in a rigid and nonrigid manner--over time, under different viewing conditions, and with altering appearances. Three experiments investigated the underlying mechanism that is more flexible than has often been supposed. The experiments used highly familiar faces that were first inspected as configurally manipulated versions.

The control of attention to faces.

Humans attend to faces. This study examines the extent to which attention biases to faces are under top-down control. In a visual cueing paradigm, observers responded faster to a target probe appearing in the location of a face cue than of a competing object cue (Experiments 1a and 2a).

Attention capture by faces.

We report three experiments that investigate whether faces are capable of capturing attention when in competition with other non-face objects. In Experiment 1a participants took longer to decide that an array of objects contained a butterfly target when a face appeared as one of the distracting items than when the face did not appear in the array. This irrelevant face effect was eliminated when the items in the arrays were inverted in Experiment 1b ruling out an explanation based on some low-level image-based properties of the faces.

Gaze cues influence the allocation of attention in natural scene viewing.

In two experiments we examined whether the allocation of attention in natural scene viewing is influenced by the gaze cues (head and eye direction) of an individual appearing in the scene. Each experiment employed a variant of the flicker paradigm in which alternating versions of a scene and a modified version of that scene were separated by a brief blank field. In Experiment 1, participants were able to detect the change made to the scene sooner when an individual appearing in the scene was gazing at the changing object than when the individual was absent, gazing straight ahead, or gazing at a nonchanging object.

Attentional bias to angry faces using the dot-probe task? It depends when you look for it.

A number of studies using the dot-probe task now report the existence of an attentional bias to angry faces in participants who rate highly on scales of anxiety; however, no equivalent bias has been observed in non-anxious populations, despite evidence to the contrary from studies using other tasks. One reason for this discrepancy may be that researchers using the dot-probe task have rarely investigated any effects which might emerge earlier than 500 ms following presentation of the threat-related faces. Accordingly, in the current study we presented pairs of face stimuli with emotional and neutral expressions and probed the allocation of attention to these stimuli for presentation times of 100 and 500 ms.

The influence of head contour and nose angle on the perception of eye-gaze direction.

We report seven experiments that investigate the influence that head orientation exerts on the perception of eye-gaze direction. In each of these experiments, participants were asked to decide whether the eyes in a brief and masked presentation were looking directly at them or were averted. In each case, the eyes could be presented alone, or in the context of congruent or incongruent stimuli In Experiment 1A, the congruent and incongruent stimuli were provided by the orientation of face features and head outline.

Configural processing in the perception of eye-gaze direction.

Traditional accounts of gaze perception emphasise the geometric or configural cues present in the eye; the position of the iris in relation to the corner of the eye, for example. This kind of geometric account has been supported, in part, by findings that gaze judgments are impaired in faces rotated through 180 degrees, a manipulation known to disrupt the processing of relations between facial elements. However, studies involving this manipulation have confounded inversion of the face context with inversion of the eye region.

Unusual bony colorectal metastases in post-hepatometastasectomy patients.

Colorectal cancer metastases occur predominantly in the liver, with extrahepatic sites being far less common and equally distributed in the lung, brain, skin, and bone. We report two cases of unusual bony metastases of colorectal cancer. A 55-year-old man underwent an abdominoperineal resection for a Dukes B carcinoma of the rectum, followed 17 months later by a right hemihepatectomy for metachronous liver metastases.
