Individual differences within and across attentional blink tasks revisited

When the second of two targets (T2) is presented in close temporal proximity (within 200–500 ms) to the first (T1), the accuracy for reporting T2 is reduced relative to when the targets are separated by longer durations; this effect is known as the attentional blink (AB). Two recent studies have shown that individual differences in the magnitudes of the AB are stable both within a single testing session and over time. While one study found a large positive correlation between AB magnitudes when there was an attentional-set/task switch between T1 and T2 and when there was not, the other study found no relationship between the switch and no-switch paradigms. The present study was conducted to clarify this discrepancy by examining the reliability of, and relationships among, individual differences in AB performance on five different versions of the standard dual-target RSVP paradigm, three of which involved an attentional-set/task switch between T1 and T2, and two of which did not. Participants completed all five paradigms, and then returned 7–10 days later to again complete the same paradigms. The performance on all five versions was reliable both within and across testing sessions, demonstrating again that individual differences in AB performance are stable over time. In addition, all five AB versions were significantly intercorrelated, although the strengths of the relationships differed depending on the extent to which the T1 and T2 attentional sets/tasks overlapped. These findings provide evidence that multiple distinct dual-target RSVP tasks do share underlying variability, providing support for the use of different versions of the paradigm in the literature.     

Recognition and retrieval of proper names: Age differences in the fan effect

Abstract

A spreading activation model was applied, to explain. some aspects of retrieval failure for proper names. The fact that retrieval failures occur more frequently for well-known names than for unfamiliar names, and the increased incidence of name blocking in the elderly, are both interpreted in terms of the fan effect. Fanning is created when multiple far are known about a single person and results in slower and more error-prone retrieval, but the fan effect can be counteracted if the facts form an integrated set. Three groups of subjects—young, middle-aged, and elderly—learned sets of name-attribute statements in three conditions. In the no-fan condition, each name was uniquely paired with a single attribute; in the fan condition, each name was linked with three different attributes; in the crossed-fan condition, different names shared some of the same attributes. Verification RTs and cued recall responses showed that all subjects found the crossed-fan condition most difficult, but, when name-attribute links were not crossed, young and middle-aged subjects were able to counteract the fan effect by integrating the facts into a unified representation. Elderly subjects were less able to integrate effectively and were more susceptible to the fan effect.     

Gender differences in children's divergent thinking

Block's theory (1984) of gender differences was examined to determine if it could explain inconsistencies in the reports of gender differences and the personality correlates of creativity in children. Additionally, an investigation of 244 gifted children in grades 4 to 8 is described. Two divergent thinking tests, each with a familiar and an unfamiliar item, were used to test cognitive style. The Dependency Proneness Test was used to measure independence, and the Fundamental Interpersonal Relations Orientation‐Behavior Children was used to measure social orientation. No gender differences were found on the measures of personality and cognitive style, and no significant association was found between cognitive style and personality. The results were discussed in light of the moderating influence of sex‐role flexibility and the relative freedom boys and girls experience in peer groups and play.     

A Look Beyond the Mirror—What He Saw and I Didn't: Reply to Commentary

Altman's commentary challenged this author on both a personal and a theoretical level. On a personal level, she was encouraged to explore her knowing at one moment but not knowing at another, her own self-interest in the position of beneficiary. Thus, the mechanism of disavowal that underpins liberal racism was revisited in a more clinically oriented manner.

On a theoretical level, Altman's response invited a more refined exploration of liberal racism as it differs from blatant racism. It also facilitated a more nuanced application of Lacanian and Kleinian theory to this matter.     

Correspondence: Mental health care in South Africa

Shame has been an insufficiently studied emotion in psycho-analytic literature until recently, mainly because it tended to be ‘absorbed’ under the concept of guilt. Now it is recognized as a powerful affect of pregenital origin, linked with narcissism and the ego ideal. Shame can be a motivation for achievements and social adaptation, it can protect an individual's integrity and can be a modulator of interpersonal relatedness; it can also function as a defence or initiate psychopathological states, such as depression, self-alienation, identity confusion or acting out. In adolescence shame is a ubiquitous phenomenon, as this developmental stage consists of all the parameters that can trigger feelings of shame. The emotional regression connected with the emergence of primitive impulses, conflicts and defences; the grandiose phantasies and the increased narcissism; the preoccupation with bodily functions and body image; the tendency to idealization and the need for social acceptance constitute the matrix within which shame and shame-derived feelings can develop. Shame is discussed as it is experienced by young patients and often by the therapist. Shame in the countertransference and during supervision is also considered. Stress is put on the importance of taking shame into account as a fundamental factor in psychotherapy with adolescents, particularly in relation to the establishment of the therapeutic relationship, understanding and interpretations. The thesis is illustrated with clinical vignettes.     

Body Image Scores and Varieties of Consciousness

Dreams, depersonalization experiences, daydreams, and autobiographies were compared in regard to barrier, penetration, and neutral imagery and action scores. Significant differences were found between these varieties of consciousness on all three scores. Only barrier scores showed significant differences between males and females.     

Does number data entry rely on the phonological loop?

Two experiments investigated effects of articulatory processing on number data entry. Participants entered four‐digit numbers presented as either words or numerals on a keyboard, either under an articulatory condition or in silence. In Experiment 1, the articulatory condition was articulatory suppression; in Experiment 2, it was vocalisation. In Experiment 1, the articulatory suppression group typed initial digits faster than the silent group, but for subsequent digits, the opposite pattern occurred at least with word stimuli. In Experiment 2, the silent group typed initial digits faster but typed subsequent digits somewhat slower than the vocalisation group. Thus, articulation of numbers, which promotes entry into the phonological loop of working memory, retards processing of initial digits but enhances processing of subsequent digits.     

High perceptual load causes inattentional blindness and deafness in drivers

ABSTRACT

Perceptual load theory of attention predicts that the level of perceptual load in a primary task affects the processing of additional stimuli. Given the lack of ecologically valid evidence for the model, the current study assessed the effect of perceptual load on driver awareness during simulated driving tasks. The results showed that perceptual load dramatically affected driver awareness for visual and auditory stimuli, even those that were driving relevant and safety critical (e.g. pedestrians or the sound of a car horn). The results support load theory and suggest that perceptual load may be an important factor in driver safety.     

Atypical updating of face representations with experience in children with autism

Face identity aftereffects are significantly diminished in children with autism relative to typical children, which may reflect reduced perceptual updating with experience. Here, we investigated whether this atypicality also extends to non‐face stimulus categories, which might signal a pervasive visual processing difference in individuals with autism. We used a figural aftereffect task to measure directly perceptual updating following exposure to distorted upright faces, inverted faces and cars, in typical children and children with autism. A size‐change between study and test stimuli limited the likelihood that any processing atypicalities reflected group differences in adaptation to low‐level features of the stimuli. Results indicated that, relative to typical children, figural aftereffects for upright faces, but not inverted faces or cars, were significantly attenuated in children with autism. Moreover, the group difference was amplified when we isolated the ‘face‐selective’ component of the aftereffect, by partialling out the mid‐level shape adaptation common to upright and inverted face stimuli. Notably, the aftereffects of typical children were disproportionately larger for upright faces than for inverted faces and cars, but the magnitude of aftereffects of autistic children was not similarly modulated according to stimulus category. These findings are inconsistent with a pervasive adaptive coding atypicality relative to typical children, and suggest that reduced perceptual updating may constitute a high‐level, and possibly face‐selective, visual processing difference in children with autism.     

Black client,white therapist: Working with race in psychoanalytic psychotherapy in South Africa

In post‐apartheid South Africa we speak about race extensively. It permeates our workplace, weaves a thread through the fabric of our professional and personal lives, as well as our private conversations and public interactions with others. From within psychoanalytic theory, the thread weaves through the unknown content of our racialized unconscious. When there is a focus on race in the South African psychoanalytic context it largely takes the form of the struggle to articulate the complexities of working with difference, as Swartz notes, or the struggle to map out issues of race. Such struggles are not localized in South Africa, but strongly reflect a much broader struggle within the global psychoanalytic community, as mirrored in the expanding focus on race. Although the consulting rooms seem far removed from the ongoing political tensions that have recently emerged in South Africa, psychoanalytic psychotherapy remains a space of meaningful engagement with the other, and where the therapeutic dyad is one of racial difference it permits an encounter with our racialized unconscious. This article seeks to document the experience of my black client and my white response to her racial pain and struggle; in doing so, I describe the racial ‘contact’ between us and within us that triggers a racialized transference and countertransference dynamic, which contains the space for racial healing for both of us.
