Using image analysis techniques to analyze figure-copying performance of patients with visuospatial neglect and control groups.

Figure copying is often used to detect visuospatial neglect (VSN) in brain-damaged patients. We describe algorithms that enable the computation of parameters for describing figure-copying performance. The researcher can readily implement these algorithms on a computer using image analysis software, and they provide information on goodness-of-fit, relative to a standard model, as well as on dynamic aspects of subjects' performance in completing figure copies. To demonstrate the clinical utility of these algorithms, preliminary results from a group of right-hemisphere brain-damaged patients, some of whom have VSN, are compared with those for age-matched controls.     

The effects of cue modality on the quality of personal memories retrieved

We investigated the effect of cue modality on the specificity, speed, vividness, and age of autobiographical memory retrieval. Cues were presented as either an odour, a visual image, or a word label. Odour-cued memories were older, more likely to be categoric, and were slower to be retrieved. Few gender differences were found although females reported more vivid memories than males. We suggest that cue modality directly affects retrieval processes; odour cues are more likely to initiate a perceptual search strategy, in contrast to memories cued by visual images and words, which are usually conceptually/verbally mediated.     

The impact of adopting ethnic or civic conceptions of national belonging for others' treatment

National belonging is often defined in terms of "ethnic" ancestry and "civic" commitment (with the latter typically implying a more inclusive conception of belonging). The authors report three Scottish studies manipulating the prominence of these criteria. In Study 1 (N = 80), a Chinese-heritage target was judged more Scottish (and his criticisms of Scotland better received) when Scotland was defined in civic terms. In Study 2 (N = 40), a similar manipulation in a naturalistic setting showed a civic conception of belonging resulted in more help being given to a Chinese-heritage confederate. Study 3 (N = 71) replicated Study 2 and showed the effect was mediated by judgments of the confederate's Scottishness. These studies emphasize the importance of exploring how ingroup identity is defined.     

Judgments relative to patterns: how temporal sequence patterns affect judgments and memory

Six experiments studied relative frequency judgment and recall of sequentially presented items drawn from 2 distinct categories (i.e., city and animal). The experiments show that judged frequencies of categories of sequentially encountered stimuli are affected by certain properties of the sequence configuration. We found (a) a first-run effect whereby people overestimated the frequency of a given category when that category was the first repeated category to occur in the sequence and (b) a dissociation between judgments and recall; respondents may judge 1 event more likely than the other and yet recall more instances of the latter. Specifically, the distribution of recalled items does not correspond to the frequency estimates for the event categories, indicating that participants do not make frequency judgments by sampling their memory for individual items as implied by other accounts such as the availability heuristic (Tversky & Kahneman, 1973) and the availability process model (Hastie & Park, 1986). We interpret these findings as reflecting the operation of a judgment heuristic sensitive to sequential patterns and offer an account for the relationship between memory and judged frequencies of sequentially encountered stimuli.

Cognitive models of stereotype change (4): Motivational and cognitive influences

Three experiments investigating the effects of cognitive and motivational factors on stereotype change are reported. Trait ratings in all three experiments showed there to be greater stereotype-change when stereotype-inconsistent information was dispersed across many group members than when it was concentrated in only a few. A sorting task (Experiment 1) indicated that, in the concentrated conditions the stereotype disconfirmers were more strongly isolated from the rest of the group than in the dispersed conditions. Free recall protocols (Experiment 2) showed greater memory for the target exemplars when subjects anticipated interaction with a group member than when no interaction was anticipated. The questions subject chose to ask target group exemplars were also influenced by anticlpated future interaction. Subjects chose more stereotype-inconsistent questions when interactian was anticipated than when no interaction was anticipated. Experment 3 showed the impact of stereotype-inconsistent information to be greater when expectancies for the stereotyped group are weaker A cued-recall task yielded evidence of spontaneous subtyping. All these studies support the subtyping model, even in the presence of cognitive and motivational factors that might be expected to impede stereotype change.     

Process and content in a long-term PTSD therapy group for Vietnam veterans

Process and content were studied in four 16-session segments of a psychodynamically oriented therapy group for Vietnam veterans suffering from posttraumatic stress disorder (PTSD). On the Group Climate Questionnaire (GCQ-S), the group scored significantly higher in the Engaged dimension and significantly lower in the Avoiding and Conflict dimensions than contrasting samples of neurotic and psychotic groups. There was no evidence of group stages. Topics related to symptoms of PTSD were discussed most frequently (43.1%), followed by issues concerning relations with others (32.4%),general group therapy issues (13.7%), and other topics (10.8%). Clinical implications of these findings are discussed.The authors thank Tom Metzler, M.A., and Heidi Ronfeldt, B.S., for their assistance with the data analysis.Parts of this paper were presented at the American Group Psychotherapy Association Annual Meeting, February 15–20, 1993, San Diego, CA.     

School pupils' perceptions of the police that visit schools: Not all police are ‘pigs’

This paper presents data concerning young people's perceptions of the police taking part in a police—schools liaison programme. Eighty-one 14-year-old school pupils took part in 28 semi-structured group discussions concerning their perceptions of the ‘typicality’ of police officers working in their schools. Pupils clearly differentiated between these and those ‘on the street’. Central to this differentiation was the issue of police power; the perceived atypicality of the police in schools was intimately bound up with pupils' perceptions of the qualitatively different social relations that obtain between young people and the police ‘in the school’ and ‘on the street’. The implications of these data for the literatures concerning the ‘contact hypothesis’ and police—schools liaison are discussed.     

Beyond the qualitative paradigm: A framework for introducing diversity within qualitative psychology

The case for qualitative research in psychology is considered. We argue against the idea that qualitative research is merely a matter of technique or method, and question the utility of viewing it as a unitary paradigm. Rather, the links between epistemology, methodology, and method are explored within three theorized strands of qualitative inquiry, making reference to illustrative projects. Each strand is organized around a different approach to the issues of justifying and warranting psychological knowledge: (1) reliability and validity; (2) generativity and grounding; and (3) discourse and reflexivity. These are exemplified in Miles and Huberman's ‘data display’ model, Glaser and Strauss' method of ‘grounded theory’, and in various forms of ‘discourse’ analysis. Reflections upon points of contact between the three strands address two main issues: (1) rendering research publicly accountable; and (2) challenging relativism.
