Identity Fusion,Extreme Pro‐Group Behavior,and the Path to Defusion

Identity fusion refers to a visceral sense of oneness with an ingroup. For fused individuals, group membership is not a means to an end (e.g., a positive social identity). Rather, membership is an all‐absorbing goal in itself; little other than the group matters. Group membership is also seen as enduring, sustained by chronically activated psychological structures as well as features of the context. Fellow group members are likewise seen as permanent members of the group, as they are members of the ingroup “family”. And just as family members are compelled to make extreme sacrifices for their family, so too are highly fused individuals – including even the ultimate sacrifice. These efforts to protect the ingroup can have negative consequences when, for example, people become strongly fused to groups that are devoted to extreme, anti‐social behaviors. In such instances, it may be prudent to encourage “defusion” from the group, but the emotional investment associated with fusion may thwart such efforts. We discuss the implications of these and related considerations.     

The impact of stress on mothers' memory of a natural disaster

The effects of stress on mothers' recall for a major hurricane were studied. Stress was objectively defined as low, moderate, or high according to the severity of home damage. This study of 96 mothers was conducted concurrently with L. E. Bahrick, J. F. Parker, R. Fivush, and M. Levitt (1998), allowing the authors to compare child and adult recall as a function of the same stressor. There was a quadratic relationship between storm severity and total recall for adults, similar to their children. Mothers' recall increased from low to moderate severity, but recall at moderate severity did not differ from high severity. These findings help clarify the effects of stress on the amount and type of information adults recall in retrospective accounts of naturalistic, temporally extended events.     

The relation between angle of display and performance in a prolonged visual task

An experiment is described to test the relation between angle of display and performance in prolonged visual tasks, using the Clock Test in three positions of display surface, vertical, at an angle of 45 degrees to the horizontal, and horizontal. In every case the line of regard was kept at right-angles to the display surface. The results indicate that significantly fewer stimuli are missed in the vertical position of the display surface than in the other two.

The deterioration observed in the second half-hour of the original Clock Test experiments was not found in the present experiment, and two possible reasons for this are discussed briefly.     

The relation of an environmental variable to performance in a prolonged visual task

In a previous paper (Fraser, 1950) on the relation between angle of display and performance in a prolonged visual task (Mackworth's Clock Test), it was suggested that the presence or absence of the experimenter might affect performance on vigilance tasks. In Mackworth's original experiments (Mackworth, 1950) the subject was in a closed cabinet by himself, and as far as possible all external noise and stimuli were excluded. In the angle of display experiment, the writer sat in the same room as the subject, out of his sight, and there was no particular attempt to exclude the ordinary external noises, etc. It seemed worth while to follow up the previous experiment with another to test the hypothesis that the presence or absence of the experimenter might influence performance in such a task. A new apparatus was devised for this purpose, which possesses some advantages over the Clock Test.     

Communicating power and resistance: exploring interactions between aboriginal youth and non-aboriginal staff members in a residential child welfare facility

Aboriginal youth are highly overrepresented within the child welfare system. High-risk youth are often placed in out-of-community residential placements. Such residential placements have been described by some as a continuation of colonial practices. Using communication theory as a conceptual model, we propose a qualitative analysis of micro-interactions that take place between Aboriginal youth and non-Aboriginal workers during the management of high-risk behaviors within a residential program. Three broad categories of interaction emerge from the data: complementary, symmetrical/complementary (where youth show a form of submission despite resistance), and symmetrical (characterized by a power struggle). Despite the diversity of interactions along this symmetrical to complementary continuum, interventions always start and finish in the same fashion. Moreover, the nature of interactions depended mostly on how quickly youth accepted the consequences of their behaviors. We also extracted five categories related to culture, race or context that are perceived as influencing the interactions that take place between staff and youth. The analysis of micro-interactions within clinical, organizational, social and historical contexts points to mechanisms by which asymmetrical power relations may be replicated on a day-to-day basis despite the best intentions of residential workers.     

The modified star graph and the petal diagram: two new visual aids for discrete alternative multicriteria decision making

Many studies have looked into the provisions of visual aids to multicriteria decision making. However, most of them have separated the display of alternative profiles and criteria weight information into two displays. This makes the analysis of the relationship between the criteria and alternatives and the effect of changing the criteria weights on the decision difficult. In this study, displays that can incorporate the display of both alternative profiles and criteria weight information for discrete alternative multicriteria decision-making problems are examined. The simple additive model is the multicriteria analysis method used. The result is two new visual aids for representing data of multicriteria decision-making problems, the modified star graph and the petal diagram. This paper discusses the two displays and compares their strengths and weaknesses. The results of a preliminary test conducted to evaluate the effectiveness of the displays are also included. © 1998 John Wiley & Sons, Ltd.     

African American Muslim Women: An Invisible Group

Little is written about Islam and African American women or men from a psychosocial perspective. Most of the literature is on the historical and political development of the Nation of Islam, and the differences among the male leaders. This focus obscures the fact that the majority of African Americans Muslims belong to traditional Islamic groups. Drawing upon a variety of literatures, this paper seeks to explore some background information about Islam and the African American community, and to understand the appeal of Islam to African American women.     

The extent of working memory deficits associated with Williams syndrome: exploration of verbal and spatial domains and executively controlled processes

The present study investigated verbal and spatial working memory (WM) functioning in individuals with the neuro-developmental disorder Williams syndrome (WS) using WM component tasks. While there is strong evidence of WM impairments in WS, previous research has focused on short-term memory and has neglected assessment of executive components of WM. There is a particular lack of consensus concerning the profile of verbal WM functioning in WS. Here, WS participants were compared to typically developing participants matched for (1) verbal ability and (2) spatial ability (N = 14 in each of the 3 groups). Individuals with WS were impaired on verbal WM tasks, both those involving short-term maintenance of information and executive manipulation, in comparison to verbal-matched controls. Surprisingly, individuals with WS were not impaired on a spatial task assessing short-term maintenance of information in memory (remembering spatial locations) compared to spatial-matched controls. They were, however, impaired on a spatial executive WM task requiring the manipulation of spatial information in memory. The present study suggests that individuals with WS show WM impairments that extend to both verbal and spatial domains, although spatial deficits are selective to executive aspects of WM function.     

Interpreting the effects of image manipulation on picture perception in pigeons (Columba livia) and humans (Homo sapiens)

The effects of picture manipulations on humans' and pigeons' performance were examined in a go/no-go discrimination of two perceptually similar categories, cat and dog faces. Four types of manipulation were used to modify the images. Mosaicization and scrambling were used to produce degraded versions of the training stimuli, while morphing and cell exchange were used to manipulate the relative contribution of positive and negative training stimuli to test stimuli. Mosaicization mainly removes information at high spatial frequencies, whereas scrambling removes information at low spatial frequencies to a greater degree. Morphing leads to complex transformations of the stimuli that are not concentrated at any particular spatial frequency band. Cell exchange preserves high spatial frequency details, but sometimes moves them into the "wrong" stimulus. The four manipulations also introduce high-frequency noise to differing degrees. Responses to test stimuli indicated that high and low spatial frequency information were both sufficient but not necessary to maintain discrimination performance in both species, but there were also species differences in relative sensitivity to higher and lower spatial frequency information.
