Eliciting donations to disaster victims: Psychological considerations

Predictors of monetary donations to victims of humanitarian disasters were examined. Participants (N = 219) chose between donating to different scenarios and justified their choices in an open response format. This was followed by a questionnaire. The perceived extent of the victims’ Need, the Impact of a potential donation, and the Amount donated by others all influenced donation decisions. There was a three‐way interaction between these factors: The perceived Need for help only mattered if the perceived Impact of a donation was high, and the perceived Amount donated by others was small. Implications for theory and practice are discussed.     

Emotional enhancement of immediate memory: Positive pictorial stimuli are better recognized than neutral or negative pictorial stimuli

We examined emotional memory enhancement (EEM) for negative and positive pictures while manipulating encoding and retrieval conditions. Two groups of 40 participants took part in this study. Both groups performed immediate implicit (categorization task) and explicit (recognition task) retrieval, but for one group the tasks were preceded by incidental encoding and for the other group by intentional encoding. As indicated by the sensitivity index (d'), after incidental encoding positive stimuli were easier to recognize than negative and neutral stimuli. Participants' response criterion was more liberal for negative stimuli than for both positive and neutral ones, independent of encoding condition. In the implicit retrieval task, participants were slower in categorizing positive than negative and neutral stimuli. However, the priming effect was larger for emotional than for neutral stimuli. These results are discussed in the context of the idea that the effect of emotion on immediate memory enhancement may depend on the intentionality to encode and retrieve information.     

Clinical tests of memory in dementia, depression, and healthy aging

In Study 1, carefully screened elderly adults with primary degenerative dementia or major depression were compared to healthy aged control subjects on three tests of learning and memory: the Benton Visual Retention Test, Inglis Paired-Associate Learning Test, and the Fuld Object-Memory Evaluation (OME). The sharpest distinction in performance among the groups was observed on the OME, and discriminant equations based on this test correctly classified a high percentage (greater than or equal to 90%) of participants. Study 2 applied the classification rules derived in the first investigation to an unselected series of geropsychiatry inpatients referred for neuropsychological evaluation. There was agreement between memory test classification and general categories of clinical discharge diagnosis (organic vs. functional) for 21 of 25 patients, and with status at follow-up approximately 18 months later. Predictive value computations suggested that the OME is more accurate in confirming true dementia than in detecting dementia syndromes associated with functional disorders.     

Production of narrative and procedural discourse in aphasia

The study described the abilities of a group of 10 aphasics and 10 normals to produce narrative and procedural discourse. The experimental tasks included telling stories, producing summaries, giving morals to the stories, and producing procedures. The variables examined in the investigation included features of sentential grammars, such as amount of embedding, and features of discourse grammars, such as occurrence of elements of superstructure in narrative. Additionally, raters assessed the content and clarity of the discourses. The results showed that aphasics produced well-structured narrative and procedural discourse. Aphasics' discourse errors differed only in degree, not qualitatively, from those of normals. The language of the aphasics' discourses was reduced in both complexity and amount. It was found that the aphasics had difficulties in producing summaries and giving morals for the stories when compared with the normals. Both the content and clarity of the discourses produced by the aphasics were rated lower than those produced by the normals.     

The Specter of Metaphysics in Counseling Research and Practice: The Qualitative Challenge

After decades of scientific research, the specter of metaphysics pervades and hinders virtually all aspects of counseling research, theory, and practice. Qualitative research is suggested as capable of coming to terms with such issues. This article notes that qualitative research will gain acceptance when it takes a significant step toward solving a major problem in the discipline. A tentative outline of an approach to metaphysical problems involving radical empiricism and phenomenology is provided. Along the way, some necessary cognitive shifts are delineated, involving dialectical and abductive reasoning processes.     

The importance of ‘mass’ in line drawings of faces

Previous research (Davies, Ellis and Shepherd, 1978; Rhodes, Brennan and Carey, 1987) has shown that accurate line drawings of familiar faces are identified rather poorly. However, artists can produce lifelike portraits with pen and ink, and Pearson and Robinson (1985) described an automatic method for producing computer-drawn sketches (‘cartoons’) of faces which appear very similar to those produced by a human artist. In this paper we show that subjects can identify famous faces depicted in such computer-drawn ‘cartoons’ almost as well as full grey-scale images. The cartoon algorithm comprises two components. One component draws lines at the locations of intensity changes corresponding to luminance valleys and edges (the ‘valledge’ detector). The other component applies a ‘threshold’ to the original intensity distribution, and replaces any area darker than threshold with black. Thus the full cartoon contains both ‘line’ and ‘mass’. Neither the valledges nor the threshold components alone were as well identified as full cartoons containing both components. The results suggest that the addition of the threshold component adds significantly to the identifiability of line drawings of faces.
