The spatial distribution of attention within and across objects

Attention operates to select both spatial locations and perceptual objects. However, the specific mechanism by which attention is oriented to objects is not well understood. We examined the means by which object structure constrains the distribution of spatial attention (i.e., a "grouped array"). Using a modified version of the Egly et al. object cuing task, we systematically manipulated within-object distance and object boundaries. Four major findings are reported: 1) spatial attention forms a gradient across the attended object; 2) object boundaries limit the distribution of this gradient, with the spread of attention constrained by a boundary; 3) boundaries within an object operate similarly to across-object boundaries: we observed object-based effects across a discontinuity within a single object, without the demand to divide or switch attention between discrete object representations; and 4) the gradient of spatial attention across an object directly modulates perceptual sensitivity, implicating a relatively early locus for the grouped array representation.     

Experience-dependent attentional tuning of distractor rejection

Irrelevant salient distractors often capture attention, but given a sufficiently specific search template, these salient items no longer capture attention. In the present experiments, we investigated whether specific target templates are sufficient to resist capture, or whether experience with the salient distractors is also necessary. To test this hypothesis, observers completed four blocks of trials, each with a different-colored irrelevant singleton present on half of the trials. Color singletons captured attention early within a block, but after sufficient experience with the irrelevant singletons, those singletons no longer captured attention in the second halves of the blocks. This result suggests that to resist capture, a specific target template must be accompanied by experience-dependent attentional tuning to distractor properties.     

Reduced looming sensitivity in primary school children with Developmental Co-ordination Disorder

Almost all locomotor animals are sensitive to optical expansion (visual looming) and for most animals this sensitivity is evident very early in their development. In humans there is evidence that responses to looming stimuli begin in the first 6 weeks of life, but here we demonstrate that as children become independent their perceptual acuity needs to be 50 to 100 times better than has been demonstrated in infants in order to be skilful at collision avoidance at a roadside. We have recently established that sensitivity to the detection of visual looming in 6- to 11-year-old children is significantly below that of adults (Wann, Poulter & Purcell, 2011). Here, using comparable methods, we explore looming detection sensitivity in children with Developmental Co-ordination Disorder (DCD), who show broad patterns of impairment in visuo-motor control. We presented visual simulations of approaching vehicles, scaled to represent different approach rates, to children with DCD aged between 6 and 11 years (n = 11) and typically developing age and gender matched controls (n = 11). Looming detection thresholds were measured under foveal and perifoveal viewing conditions, for isotropic expansion and isotropic expansion with simulated viewpoint motion. Our results show that there are situations in which children with DCD may fail to detect vehicles approaching at speeds in excess of 22 km/h, suggesting a developmental immaturity in looming sensitivity. This provides one of the first clear demonstrations of low-level motion processing deficits in children with DCD. The decrement observed may give rise to potential errors in the road crossing behaviour of these children, whereby approaching vehicles could be perceived as stationary. These findings further contribute towards understanding the adverse statistic that children under 9 years of age are four times more likely than adults to be involved in a road accident as a pedestrian.     

Multiple identities and career development of GLB immigrants

There has been increasing interest in the study of career development and career counselling for the gay men, lesbian women and bisexual (GLB) people given the clear link between sexual orientation and career development in the past two decades. Yet, there is still a relatively dearth of literature in this area, especially, much is unknown about the career identity and other related identity development experiences of GLB immigrant adults whose acculturation process intersects with cultural identity, race and ethnicity and sexual identity as they rebuild their careers in the host country. This article aims to explore the connections between multiple cultural identities and their affect on career development. It builds upon the current literature, uses some career development theories, and proposes career development and career counselling interventions for the target group.     

Connecting confusions with painful realities: Group analytic psychotherapy for adults with learning disabilities

Developments in the psychodynamic understanding of individuals with learning disabilities (LD) ¹ This recently-adopted term is used here. Earlier authors have used other terms to refer to such clients, including ‘mental retardation’, ‘subnormality’, ‘handicap’, and ‘learning difficulties’. View all notes have included the exploration of the relationships between biological and psychosocial vulnerabilities, and emphasis on separation and individuation processes. While the normalisation movement encourages access to mainstream counselling and psychotherapy services, confusions persist about the suitability of people with LD for analytic psychotherapies. Given some recent positive accounts of group psychotherapy, in this paper we aim to explore the opportunities and challenges associated with an outpatient analytic group for adults with LD.

The group's background, members, material, and outcomes illustrate the emerging themes of confusions, connections, and painful realities for adults with LD. Attempts to understand individual and group transference and therapists' countertransference emphasised the primacy of dependence, handicap, and loss within the content and process of the group.

We encourage further consideration of the psychodynamics, service, and research issues involved in psychotherapy for adults with LD.     

Flashbulb Memories for September 11th can be Preserved in Older Adults

Flashbulb memories (FMs) are vivid, long-lasting memories for the source of surprising, arousing news. Laboratory studies have consistently found that older adults, especially those with below-average frontal lobe (FL) function, are impaired in source memory relative to young. We tested memory for the source of news concerning the September 11th terrorist attacks in older adults with high or low frontal lobe function and in young people. We found no age differences in source memory a year after the event and no differences related to FL function. Flashbulb memories may be different from usual cases of source memory because of their emotional content, personal importance, or social relevance.

Grandiosity,trauma and self

Distortions and inversions of Kohut's phase of grandiosity play a major role in multi-generational patterns of child-abuse and neglect. Such families are considered ‘upside down’ in their organization: parents enact unmet needs for mirroring and grandiose assertion, while the child experiences anxiety and endures a split between defensive compliance and a turbulent, trauma-ridden inner life. Within the space of this lonely inner life, the child fixates on atavistic power fantasies and dreams of possessing or controlling its objects. Hence, distortions of power and grandiosity replicate themselves from one generation to the next. The therapeutic play of children from upside down families typically passes through four phases: 1) re-enactment of trauma vignettes; 2) restoration of appropriate grandiose and mirroring themes; 3)restoration of rudimentary empathic abilities and empathy longing; 4) the search for an appropriate parenting object. Psycho-analytically based play therapy is effective when combined with other interventions to stabilize the child's milieu.     

A comparison of types of support for lower-skill workers: Evidence for the importance of family supportive supervisors

The work–family literature to date does not offer a clear picture in terms of the relative importance of different types of supports for balancing work and family demands. Grounded in conservation or resources theory, we develop an integrative model relating multiple forms of social support, both formal (i.e., work–life benefit use) and informal (supervisor work–family support and family support) to work-interference-with-family and family-interference-with-work and task and contextual performance. We chose to focus our study on lower-skill workers because, despite being a relatively large segment of the workforce, these workers are relatively understudied in the work–family literature. Results revealed that supervisor support is a key form of support in this sample. Supervisor support had negative same domain (work-interference-with-family) and cross domain (family-interference-with-work) effects with work–family conflict, as well as positive relationships with task and contextual performance. Family support was negatively related to family-interference-with-work; whereas use of work–life benefits was not significantly related to either form of work–family conflict or any of the performance variables. The implications of our results for conservation of resources theory and practical implications to employers of lower-skill workers are discussed.
